Notes added by Tim Davis, Jan 6, 2021
cpu_features added to GraphBLAS, with changes suggested by
https://github.com/google/cpu_features/pull/211 , which renames
./src/impl_aarch64_linux_or_android.c to ./src/impl_aarch64.c renamed; and
modifies it:
18c18
< #if defined(CPU_FEATURES_OS_LINUX) || defined(CPU_FEATURES_OS_ANDROID)
---
> #if defined(CPU_FEATURES_OS_LINUX) || defined(CPU_FEATURES_OS_ANDROID) || defined(CPU_FEATURES_OS_MACOS)
149c149
< #endif // defined(CPU_FEATURES_OS_LINUX) || defined(CPU_FEATURES_OS_ANDROID)
---
> #endif // defined(CPU_FEATURES_OS_LINUX) || defined(CPU_FEATURES_OS_ANDROID) || defined(CPU_FEATURES_OS_MACOS)
cpu_features/test/CMakeLists.txt is also modified:
diff -ar ../../cpu_features/test/CMakeLists.txt ./test/CMakeLists.txt
74c74
< add_executable(cpuinfo_aarch64_test cpuinfo_aarch64_test.cc ../src/impl_aarch64_linux_or_android.c)
---
> add_executable(cpuinfo_aarch64_test cpuinfo_aarch64_test.cc ../src/impl_aarch64.c)
Makefile added by Tim Davis (no longer needed however)
GraphBLAS does not use the cpu_features/CMakeLists.txt to build a separate
library for cpu_features. Instead, in #include's all the source files and
include files from cpu_features into these files:
../Source/GB_cpu_features.h
../Source/GB_cpu_features_impl.c
../Source/GB_cpu_features_support.c
the cpu_features code is embedded in libgraphblas.so and libgraphblas.a
directly
