# 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.
