memory: switch loop condition around in blas_memory_free
...
Before this commit, the "position < NUM_BUFFERS" loop condition from
blas_memory_free will be completely optimized away by GCC. This is
because the condition can only be false after undefined behavior has
already been invoked (reading past the end of an array). As a
consequence of this bug, GCC also removes the subsequent if statement
and all the code after the error label because all of it is dead.
This commit switches the loop condition around so it works as intended.

Added COMMONOBJS to driver/others CMakeLists.txt.

Moved functions into util cmake file.

Added paramater to GenerateObjects for defines that affect all sources.

Added empty set to the combinations generated by AllCombinations.

8d9b196e0d
Moved loop over define combos into a function.
...
This function takes a set of sources and a set of preprocessor
definitions. It will iterate over the sources and build an object
file for each combination of preprocessor definitions for each
source file.

Updated level3/CMakeLists with correct defines using all combos.
2015-01-30 11:21:50 -06:00
dbdca7bf0c
Added first pass at driver/level3 Makefile conversion.
...
Added a rather convoluted CMake function to find all combinations
of a given list. This will be useful for the object files that are
compiled multiple times with different combinations of preprocessor
definitions.

prebuild.cmake now reads the output from getarch into CMake vars.

getarch now compiles and sets config.h defines properly.
...
Still isn't parsed into CMake variables, and getarch_2 needs to
get the same treatment.

Added CORE define to config.h in prebuild.cmake (temporarily).

Fix link error on Linux/musl.
...
get_nprocs() is a GNU convenience function equivalent to POSIX2008
sysconf(_SC_NPROCESSORS_ONLN); the latter should be available in unistd.h
on any current *nix. (OS X supports this call since 10.5, and FreeBSD
currently supports it. But this commit does not change FreeBSD or OS X
versions.)

added experimental support for big numa machines
