# Determine the host CPU feature set and determine the best set of compiler
|
||||
# flags to enable all supported SIMD relevant features. Alternatively, the
|
||||
# target CPU can be explicitly selected (for generating more generic binaries
|
||||
# or for targeting a different system).
|
||||
# Compilers provide e.g. the -march=native flag to achieve a similar result.
|
||||
# This fails to address the need for building for a different microarchitecture
|
||||
# than the current host.
|
||||
# The script tries to deduce all settings from the model and family numbers of
|
||||
# the CPU instead of reading the CPUID flags from e.g. /proc/cpuinfo. This makes
|
||||
# the detection more independent from the CPUID code in the kernel (e.g. avx2 is
|
||||
# not listed on older kernels).
|
||||
#
|
||||
# Usage:
|
||||
# OptimizeForArchitecture()
|
||||
# If either of Vc_SSE_INTRINSICS_BROKEN, Vc_AVX_INTRINSICS_BROKEN,
|
||||
# Vc_AVX2_INTRINSICS_BROKEN is defined and set, the OptimizeForArchitecture
|
||||
# macro will consequently disable the relevant features via compiler flags.
