commit b65cdc57d9e51fa00e3c03539cfb7e045707d0f4 (HEAD, tag: 0.0.5, origin/master, master)
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Sun Mar 24 20:01:49 2013 -0500
Migrated 'bl2' prefix to 'bli'.
Details:
- Changed all filename and function prefixes from 'bl2' to 'bli'.
- Changed the "blis2.h" header filename to "blis.h" and changed all
corresponding #include statements accordingly.
- Fixed incorrect association for Fran in CREDITS file.
commit 132bffcef7441f32d02cc7485aef6a0648e0ef1e
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Sun Mar 24 18:49:36 2013 -0500
Removed several 'old' directories and files.
Details:
- Removed most of the 'old' directories scattered throughout the framework,
which includes alternate/half-baked/broken implementations.
commit 551ea4767a3ea6c263f12aaca94bc2642cee4cfa
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Sun Mar 24 18:00:10 2013 -0500
Removed #include "blis2.h" from low-level headers.
Details:
- Removed #include of "blis2.h" from various lower-level, operation-specific
header files throughout the framework. Given that these low-level headers
are included within #blis2.h in a very specific order, #include'ing blis2.h
within them directly is unnecessary.
commit bc7b318ed0960edeb4537797dd8c91de0d942ca9
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Fri Mar 22 17:18:58 2013 -0500
Added cpp guards to conflicting libflame typedefs.
Details:
- Added cpp guards around the definitions of dim_t, scomplex, and dcomplex.
This is a temporary hack to allow interoperability with libflame. (Similarly
temporary changes are being made to libflame's type definitions file.)
commit f469907503fcdc24dff0174c569170e6e756e045
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Fri Mar 22 15:20:15 2013 -0500
Renamed MAX_PREFETCH_BYTE_OFFSET to MAX_PRELOAD_.
Details:
- Renamed BLIS_MAX_PREFETCH_BYTE_OFFSET to
BLIS_MAX_PRELOAD_BYTE_OFFSET since "prefetch" is kind of a loaded word
(e.g. "prefetch" instructions, which are different than the particular
kind of prefetching/preloading referred to by this constant).
commit d1023bfbc6668a58a01ee4f82ded2319911e7b19
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Fri Mar 22 15:09:59 2013 -0500
Removed build/old directory.
commit 718888849c48d99f83eea6b8f83bc1998cffef7e
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Fri Mar 22 15:07:01 2013 -0500
Deprecated 'flame' configuration.
Details:
- Removed 'flame' configuration, as it was horribly out-of-date.
- Comment changes to bl2_blocksize.c and bl2_mem.c.
commit bba38cf4e9d28058c14483f44fa074a6d2852ad9
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Tue Mar 19 18:07:40 2013 -0500
Added missing conjbeta argument to scald.
commit 1f82b51d06d0279dded3f2b87ba59403f3ed0af6
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Mon Mar 18 15:37:20 2013 -0500
Relocated packed mem_t dimension fields to obj_t.
Details:
- Removed the m and n (and elem_size) fields from the mem_t object, and added
m_packed and n_packed fields to obj_t. These new fields track the same as
the old ones. From an abstraction standpoint, it seemed awkward to store
those dimensions inside the mem_t.
- Updated interfaces to bl2_mem_acquire_*() so that only a byte size argument
is passed in, instead of m, n, and elem_size.
- Updated bl2_packm_init_pack() and bl2_packv_init_pack() to inline the
functionality of bl2_mem_alloc_update_m() and bl2_mem_alloc_update_v(),
respectively.
- Updated packm variants to access the packed length and width fields from
their new locations.

Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Mon Mar 18 10:37:03 2013 -0500
CHANGELOG update.
commit e7d41229d3b1674e74f47d7f29fae004a745201a (tag: 0.0.4)
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Fri Mar 15 17:12:36 2013 -0500
Re-implemented contiguous memory allocator.
Details:
- Completely re-wrote the contiguous memory allocator (bl2_mem.c). The new
allocator instantiates and initializes three separate memory pool objects,
each one associated with a separate array of contiguous memory blocks, each
block of fixed and uniform size. (The three pools are for allocating mc-by-kc
blocks of A, kc-by-nc panels of B, and mc-by-nc panels of C.) The pool
objects use a stack structure internally to track which blocks in the region
have been "checked out" to a thread and which are still available. Critical
regions are now clearly marked and adaptable to parallel environments (e.g.
OpenMP). Memory pools are set up when bl2_init() is called.
- Added a new field to the packm control tree node, which indicates what kind
of packed buffer is being allocated. The enumerated type for this argument
is defined as packbuf_t in bl2_type_defs.h.
- Updated level-3 _cntl.c files to pass in the appropriate value for a new
packbuf_t argument to bl2_packm_cntl_obj_create().
- Moved some macros called by packm_init_pack() from bl2_obj_macro_defs.h to
bl2_mem_macro_defs.h.
- Added BLIS_MAX_NUM_THREADS to bl2_config.h, which we use as the default
number of blocks of A reserved for the memory allocator.
- Deprecated bl2_align_dim(). Replaced usage with that of
bl2_align_dim_to_mult(). Turns out that typically we don't need to align
a dimension to the system alignment, since that value has to do with
starting addresses, whereas the values we are dealing with are unitless
dimensions.
commit 1e76cae00cb0a04544aaae1ade878686b238d283
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Fri Mar 15 12:21:42 2013 -0500
Perform her2k var1 loops in sequence.
Details:
- Changed variant 1 of her2k so that the two rank-k products are computed
and accumulated in sequence rather than fused into one loop. This is
necessary if BLIS is to be configured to provide only enough contiguous
memory for one panel of B.
commit c95c270eba91ae4efc26603beddfd0292caa919b
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Thu Mar 7 14:42:15 2013 -0600
Enhanced tracking of dimensions for mem_t objects.
Details:
- Added new fields to mem_t struct definition to track the allocated (as
opposed to the currently used) dimensions of the memory region. This
allows packm_init() to be more robust in situations where memory is
already allocated but is more than needed for the current packing job.
- Updated logic in bl2_obj_set_buffer_with_cached_packm_mem() macro, used
in packm_init(), to update the "currently used" dimensions of the mem_t
object if the requested dimensions are smaller than the allocated
dimensions.
commit e99281a0f41d482fddeffa239bfc8e13e6d13d4b
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Thu Mar 7 14:00:10 2013 -0600
Fixed test suite flop formulas for ops with side.
Details:
- Fixed incorrect flop counts in test suite modules for hemm, symm, trmm,
trmm3, and trsm.
- Comment updates in herk macro-kernels.
commit ef8cbfc44dd620fdcbdb51cdb173217194bebe31
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Sat Mar 2 12:47:06 2013 -0600
Added "version" to .gitignore.
Details:
- Added "version" to .gitignore file so that the file does not show up when
running 'git status', or accidentally get pulled into the index when
running 'git add' or 'git add --all'.
commit e9e0747c2f6c178f53ac46ab794acbb7b8c4fea8
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Sat Mar 2 12:43:54 2013 -0600
Removed version file from version control.
Details:
- Removed version file from version control to prevent git errors that occur
when trying to pull new commits.
commit bb612f864e9c17dd9805e9446840f02259619469
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Fri Mar 1 12:55:42 2013 -0600
Updated behavior of bl2_obj_induce_trans() macro.
Details:
- Changed bl2_obj_induce_trans() so that the transposition bit is no longer
updated as part of the macro. All current uses of the macro have been
coupled with instances of bl2_obj_set_trans() to clear the bit.
- Added Jed to CREDITS file.
commit f24e29b789e7314764a818ceb3063126936c986f
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Fri Feb 22 18:15:41 2013 -0600
Replaced banded/packed BLAS2 stubs with f2c code.
Details:
- Retired the blas2blis wrappers that simply called abort with a "not yet
implemented" message. This includes all of the level-2 banded and packed
routines.
- Replaced the aforementioned with the corresponding netlib implementations
having been run through f2c (with some customization).
- Added directories named 'attic' to build/gen-make-frags/ignore_list.
commit 1454c1a14207766dfed372b8e38b47fa384f5198
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Fri Feb 22 12:38:45 2013 -0600
Moved Fortran name-mangling macro to bl2_config.h.
Details:
- Moved the Fortran-77 name-mangling macros from bl2_blas_macro_defs.h to the
configuration directory (bl2_config.h, specifically) given that it can be
expected to be tweaked by some developers.
commit ede75693e5a36c6006087c4a7df834175b604504 (tag: 0.0.3)
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Fri Feb 22 12:11:24 2013 -0600
Implemented blas2blis compatibility layer.
Details:
- Added the blas2blis compatibility layer, located in frame/compat. This
includes virtually all of the BLAS, including banded and packed level-2
operations.
- Defined bl2_init_safe(), bl2_finalize_safe(). The former allows a conditional
initialization, which stores the "exit status" in an err_t, which is then
read by the latter function to determine whether finalization should actually
take place.
- Added calls to bl2_init_safe(), bl2_finalize_safe() to all level-2 and
level-3 BLAS-like wrappers.
- Added configuration option to instruct BLIS to remain initialized whenever
it automatically initializes itself (via bl2_init_safe()), until/unless the
application code explicitly calls bl2_finalize().
- Added INSERT_GENTFUNC* and INSERT_GENTPROT* macros to facilitate type
templatization of blas2blis wrappers.
- Defined level-0 scalar macro bl2_??swaps().
- Defined level-1v operation bl2_swapv().
- Defined some "Fortran" types to bl2_type_defs.h for use with BLAS
wrappers.
commit 995edf43e21c1868732dbdd7fee14b08730218bd
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Thu Feb 21 14:30:50 2013 -0600
Updated version file. (Forgot to in prev commit).
commit e823b08aaf7b65ecc6ddc30570709ea8a4b52aa7
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Thu Feb 21 12:00:17 2013 -0600
Fixed some scalar types in BLAS-like Herm APIs.
Details:
- Some of the scalars of Hermitian operations, such as alpha in her,
alpha and beta in herk, and beta in her2k, need to be real. These
arguments were typed incorrectly as the complex types. This has been
fixed. Note the issue was only present in the BLAS-like APIs for
these operations (not the native object-based interfaces).
commit 5ece050a669e74ba4a711d1d4669239d22d45642
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Wed Feb 20 15:50:54 2013 -0600
Updated version file. (Forgot to in prev commit).
commit f243034b8b430d4684680ea8eddfd246e73fefc0
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Wed Feb 20 14:11:36 2013 -0600
Changed API of packm_init_pack() to use blksz_t.
Details:
- Changed the interface of packm_init_pack() so that mult_m and mult_n
are passed in as type blksz_t* instead of dim_t.
- Make similar change for packv_init_pack().
commit da0c22f24107be9f33e0ea2dae52e5534b1fd0e5
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Fri Feb 15 09:59:48 2013 -0600
Minor changes to lower levels of scalm and setm.
Details:
- Removed diagx parameter from lower-level interfaces of scalm.
- Modified scalm_basic_check() to expect an object with a nonunit diagonal.
- Changed setm_unb_var1() so that having an implicit unit diagonal results
in only the strictly lower or upper triangle of the matrix being modified.
commit 2c836adadcd2a7d7f217033ac4d7fcad03d5bd55
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Thu Feb 14 10:42:56 2013 -0600
Updated beta == zero semantics of mulsc.
Details:
- Updated beta == zero semantics of mulsc. Hopefully this is the last
operation that needed updating.
- Added Devin to CREDITS file.
commit 722b66c7dcaaaa1b109e7c8b1d53fd71a9af8240
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Thu Feb 14 10:18:00 2013 -0600
Removed some calls to setv() in test modules.
Details:
- Removed calls to setv() in test modules whose sole purpose was to
initialize vectors to zero to ensure that nan's and inf's would not
taint the computation. Now that beta == zero semantics have been
updated to clear the output operand (when beta is zero), rather than
multiply against it, these setv() calls are no longer needed.
commit e6ac623a902f776c42f85eadbf76996d9770a0db
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Wed Feb 13 18:44:59 2013 -0600
Properly implemented beta == 0 semantics.
Details:
- Changed name of set0 and set0_mxn macros to set0s and set0s_mxn,
respectively.
- Added code to the following operations that sets the output operand to
zero if the corresponding scalar is zero (rather than performing the
floating-point multiply, or in the case of setv, copying the value).
This will prevent nan's and inf's from creeping into results from
uninitialized memory.

commit aedccbc85d491e41711a0c6eb0d246d8700a199a
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Wed Feb 13 18:29:53 2013 -0600
Fixed stale interface to packm_unb_var1().
Details:
- Removed the control tree from the interface to packm_unb_var1(), which
I meant to do when it was un-deprecated.
commit c23135669f7a8a545e2e11ef559bf284be8bc65c
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Wed Feb 13 13:21:00 2013 -0600
Un-deprecated packm_unb_var1.c (needed by l2 ops).
Details:
- Added bl2_packm_unb_var1() back into the mix once I realized that level-2
operations still need this routine for packing matrices. Now, whether
level-2 operations should be packing matrices to begin with is another
matter. But this fixes the segmentation fault one would have gotten when
running bl2_gemv() on a general stride matrix.
commit cf49e35f9819f9d93ebdca4703ade5abab28f6f6
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Tue Feb 12 18:39:35 2013 -0600
Removed cntl tree usage from packm implementation.
Details:
- Added new fields to obj_t info field:
- invert_diag
- pack_order_if_upper
- pack_order_if_lower
These fields allow packm_init() to embed information that begins
in the control tree into the object so that the packm implementation
does not need to use control trees at all. This is being done to aid
Bryan's DxT code generation.
- Added macros that operate on above fields.
- Changed packm_init(), packm_blk_var2(), and packm_blk_var3() according
to above changes.
- Made similar (but much simpler) changes to packv.
- Deprecated packm_blk_var1(), packm_unb_var1(), and packm_densify().
These were part of prototype implementations and are no longer needed.

commit 474bac30c99928f9e87315972bcb45c632c0b7ec
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Tue Feb 12 12:23:48 2013 -0600
Removed level-0 macros projrs, grabis.
Details:
- Replaced instances of projrs and grabis macros with newer,
more general-purpose getris.

Restored executable permissions to scripts.
Details:
- Restored executable (0755) permissions to scripts that were touched by
the recursive sed script that updated the copyright headers in the
previous commit.

CHANGELOG update.
commit 768fcebaa8be0eb936a6e7a02cd8a19438c79d99 (tag: 0.0.2)
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Mon Feb 11 13:20:44 2013 -0600
Added unified test suite, and many fixes.
Details:
- Added a highly configurable, unified test suite.
- Removed DUPB configuration constant from bl2_kernel.h and macro-kernel
header files. Now, instead, DUPB is computed as (NDUP != 1) within each
macro-kernel. This fixes a bug in trmm/trsm whereby bp was indexed into
incorrectly when DUPB was set to FALSE but the NDUP was still non-unit.
By encoding both pieces of information into one constant in _kernel.h,
it seems somewhat less likely others will encounter this bug in the
future.
- Added level-2 cache blocksizes to _kernel.h for reference configuration,
and defined blocksizes in _cntl.c files to these default values.
- Changed semantics of her2k and syr2k such that these operations no longer
expect the B matrix to already be conjugate-transposed (or just transposed
for syr2k). However, these semantics are preserved for the internal
mechanics of the implementations, including the internal back-end and all
blocked variants.
- Inserted checks for real-valued alpha and beta for herk/her2k and herk,
respectively.
- Relaxed general object structure constraints in _basic_check() for gemv, ger.
- Changed her front-end to NOT copy-cast to real projection; instead, this is
replaced by selecting either the real part or both parts within the unblocked
algorithm implementation, depending on the value of conjh.
- Added conjh to all _check routines for her so that the code knows when to
verify that alpha has an imaginary component equal to zero (for her, but
not syr).
- Changed control tree for her to forgo packing.
- Added unit diagonal support to fnormm.
- Redefined real versions of abval2s macros in terms of fabs(), fabsf().
- Redefined complex versions of sqrt2s macros using the actual "complex square
root" formula.
- Created new level-0 object-based routines, suffixed with "sc" (for "scalar").
- Defined new level-1v, -1d, and -1m versions of add and sub operations
(two-operand add and subtract).
- Added new scalar macros:
- getris: acquire real and imaginary components.
- setris: set real and imaginary components.
- addjs: addition with conjugated x.
- subjs: subtraction with conjugated x.
- Defined new utility operations:
- absumv: element-wise sum of absolute values for vector elements.
- absumm: element-wise sum of absolute values for matrix elements.
- mkherm: convert existing matrix to Hermitian.
- mksymm: convert existing matrix to symmetric.
- mktrim: convert existing matrix to triangular.
- Added various error checking routines.
- Added bl2_clock_min_diff(), which is used to more cleanly measure the
wall clock time of a code block.
- Added general stride support to bl2_obj_alloc_buffer().
- Added bl2_obj_init_scalar().
- Updated parameter mapping in bl2_param_map.c.
- Added support for queriable version string.
- Fixed a bug in the her2k macro-kernels (which currently are simply
implemented in terms of two invocations of herk) whereby beta was being
applied to both the first and second rank-k updates, rather than only
the first.
- Fixed a bug in trmm/trsm whereby transpose and right side cases were not
properly implemented due to erroneous assumptions regarding aliasing and
root objects.
- Fixed a bug in the upper triangular trsm macro-kernel in which the wrong
MR x NR block of B was being updated.
- Fixed a bug in the inverts macro in the double real case whereby the
value was typecast to float before inversion. This affected non-unit cases
of dtrsm.
- Fixed a bug in the reference kernels for gemmtrsm whereby the minus one
constant was being applied incorrectly.
- Fixed a bug in the overall treatment of non-unit alpha for trsm. The code
now mimics the rank-k strategy of gemm, whereby alpah is applied during
the first iteration of variant 3, with BLIS_ONE passed in instead for
subsequent iterations. This also required passing alpha into the macro-
kernels as well as the fused gemmtrsm micro-kernels.
- Fixed a bug in trsm_u_blk_var1 whereby the gemm macro-kernel was being
called for blocks strictly above the diagonal. While this sounds good in
theory, this cannot be done because gemm_ker_var2 expects row panels of
A to be packed from top to bottom, while for trsm_u, A is actually packed
from bottom to top due to the reverse (BR->TL) nature of the algorithm.
- Fixed a bug in packm_cxk() whereby panel packings with unit panel
dimensions were mishandled due to incorrect arguments to the copyv kernel.
Also changed the copyv kernel invocation to scal2v so that these edge
cases are properly handled when scaling is requested.
- Fixed a bug in packv_int() whereby an uninitialized object is passed in
instead of the source object.
- Fixed a bug whereby level-2 code could allocate memory dynamically via
bl2_malloc() and then attempt to free it via bl2_mm_release(). Also fixed
a potential future bug whereby a mem_t object that is actually no longer
"allocated" from the static pool is mistaken for being allocated due to
failure to NULLify the buffer when the block was most recently released.
- Fixed a bug in bl2_acquire_mpart_*() whreby the uplo field was mistakenly
toggled when the requested subpartition needed to be "reflected" due to it
residing in an unstored region.

Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Fri Jan 4 10:55:21 2013 -0600
Added missing 'd' to fused gemmtrsm function name.
commit 879a179e1dee36f0c56765f2ab91a26861019b34
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Fri Jan 4 10:37:27 2013 -0600
Added debug statements to bl2_mm_acquire_m().
Details:
- Added printf() statements to bl2_mm_acquire_m() to help debug issues
with prematurely exhausted memory pool.
- Removed 'd' from kernel names of reference kernels in clarksville
configuration's bl2_kernel.h
commit 806e74beb4eafeef620a555ffbb3f6779e29c7b6
Author: Field G. Van Zee <field@cs.utexas.edu>

Defined Frobenius norm operations.
Details:
- Added level-0 grabis macro operation to grab imaginary component of one
variable and copy it to the real component of another variable.
- Defined sumsqv operation, which computes the sum of the absolute squares
of the elements of a vector. This implementation is modeled after ?lassq
in netlib LAPACK.
- Defined fnormv and fnormm operations, which compute the Frobenius norm on
vectors and matrices, respectively. These operations are treated as one-
operand operations where the output norm value is the real projection of
the datatype of the input operand. Both operations are implemented in terms
of sumsqv.

Added GENT*R macros; tweaked bl2_machval defs.
Details:
- Added function and prototype macro-generating macros for GENTFUNCR and
GENTPROTR, which are one-operand macros with auxiliary real projection
types.
- Tweaked bl2_machval files to use new macros.
commit 2fecc88ca22142020573f168da715e8e9f3dd7de
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Thu Dec 20 11:35:14 2012 -0600
Fixed harmless macro bug in level-1m operations.
Details:
- Fixed some inconsistent usage of n_iter_max and n_iter in the two
bl2_set_dims_incs_uplo_[12]m macros. The right thing ended up happening
despite the bug, which is why I had not discovered it until now.
commit 8945db6ec9f82168cf72411ad408b4fdb44ae0d1
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Tue Dec 18 15:07:36 2012 -0600
Renamed x86,x86_64 kernels to indicate 'd' fusing.
Details:
- Renamed x86 and x86_64 kernels to contain a 'd' before the fusing shape
to emphasize that the fusing shape is not for all datatype instances, but
rather just for one (that of double-precision real). Other fusing shapes
would be proportional to their precision and domain "byte footprints".
- Corresponding changes to config/clarksville/bl2_kernel.h.
commit 6fbbdd4e194d06096ad08c5db61127be338067db
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Tue Dec 18 14:34:02 2012 -0600
More tweaks to _config.h, _kernel.h; smem tweaks.
Details:
- Moved kernel-related definitions form bl2_config.h to bl2_kernel.h.
- Replaced #define of _GNU_SOURCE with #define of _POSIX_C_SOURCE. This
accomplishes the same thing (enabling posix_memalign()) without enabling
all of the GNU extensions we don't need.
- Defined the size of the static memory pool in terms of MC, KC, and NC,
as well as two new constants that determine how many MCxKC blocks and
how many KCxNC blocks should be allocated (defined in bl2_config.h).
- In the case of static memory pool exhaustion, replaced the generic
bl2_abort() with a specific error code call.

Expanded reference packm/unpackm kernel set to 16.
Details:
- Added 10xk, 12xk, 14xk, and 16xk reference kernels for packm and
unpackm.
- Updated bl2_[un]packm_cxk() to silently use scal2m if "out of range"
kernel size is requested. (Thanks to Tyler for finding this bug.)
- Updated bl2_kernel.h to contain new _KERNEL definitions, according
to above changes, for 'reference' and 'clarksville' configurations.
- Updated CHANGELOG.
- Removed "output*.m" from .gitignore.

Added auto-detection of version string (via git).
Details:
- Added build/update-version-file.sh script for auto-detecting "version"
string and updating 'version' file accordingly. (If .git directory is
not present, then it is assumed this copy of BLIS is a downloaded
release, in which case 'version' file is left unchanged.)
- Added invocation of update-version-file.sh to configure script.
