1) Copy so that backport will be easier. 2) Make section only define if there is not a previous definition 3) Add `VEC_lo` definition for proper reg-width but in the ymm/zmm0-15 range. 4) Add macros for accessing GPRs based on VEC_SIZE This is to make it easier to do think like: ``` vpcmpb %VEC(0), %VEC(1), %k0 kmov{d|q} %k0, %{eax|rax} test %{eax|rax} ``` It adds macro s.t any GPR can get the proper width with: `V{upcase_GPR_name}` and any mask insn can get the proper width with: `{upcase_mask_insn_without_postfix}` This commit does not change libc.so Tested build on x86-64 --- sysdeps/x86_64/multiarch/reg-macros.h | 168 ++++++++++++++++++ .../multiarch/scripts/gen-reg-macros.py | 133 ++++++++++++++ sysdeps/x86_64/multiarch/x86-avx-rtm-vecs.h | 35 ++++ sysdeps/x86_64/multiarch/x86-avx-vecs.h | 47 +++++ .../x86_64/multiarch/x86-evex-vecs-common.h | 39 ++++ sysdeps/x86_64/multiarch/x86-evex256-vecs.h | 38 ++++ sysdeps/x86_64/multiarch/x86-evex512-vecs.h | 38 ++++ sysdeps/x86_64/multiarch/x86-sse2-vecs.h | 47 +++++ sysdeps/x86_64/multiarch/x86-vec-macros.h | 90 ++++++++++ 9 files changed, 635 insertions(+) create mode 100644 sysdeps/x86_64/multiarch/reg-macros.h create mode 100644 sysdeps/x86_64/multiarch/scripts/gen-reg-macros.py create mode 100644 sysdeps/x86_64/multiarch/x86-avx-rtm-vecs.h create mode 100644 sysdeps/x86_64/multiarch/x86-avx-vecs.h create mode 100644 sysdeps/x86_64/multiarch/x86-evex-vecs-common.h create mode 100644 sysdeps/x86_64/multiarch/x86-evex256-vecs.h create mode 100644 sysdeps/x86_64/multiarch/x86-evex512-vecs.h create mode 100644 sysdeps/x86_64/multiarch/x86-sse2-vecs.h create mode 100644 sysdeps/x86_64/multiarch/x86-vec-macros.h
