# NOTE [ Linking AVX and non-AVX files ]
#
# Regardless of the CPU capabilities, we build some files with AVX2, and AVX512
# instruction set. If the host CPU doesn't support those, we simply ignore their
# functions at runtime during dispatch.
#
# We must make sure that those files are at the end of the input list when
# linking the torch_cpu library. Otherwise, the following error scenario might
# occur:
# 1. A non-AVX2 and an AVX2 file both call a function defined with the `inline`
# keyword
# 2. The compiler decides not to inline this function
# 3. Two different versions of the machine code are generated for this function:
# one without AVX2 instructions and one with AVX2.
# 4. When linking, the AVX2 version is found earlier in the input object files,
# so the linker makes the entire library use it, even in code not guarded by
# the dispatcher.
# 5. A CPU without AVX2 support executes this function, encounters an AVX2
# instruction and crashes.
#
# Thus we organize the input files in the following order:
# 1. All files with no AVX-n support
# 2. All files with AVX2 support ('*AVX2.cpp')
# 3. All files with AVX512 support ('*AVX512.cpp')
