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{upper_case_GPR_name}` and any mask insn can get the proper width with: `{mask_insn_without_postfix}V` This commit does not change libc.so Tested build on x86-64 --- sysdeps/x86_64/multiarch/reg-macros.h | 358 ++++++++++++++++++ .../multiarch/scripts/gen-reg-macros.py | 124 ++++++ 2 files changed, 482 insertions(+) create mode 100644 sysdeps/x86_64/multiarch/reg-macros.h create mode 100644 sysdeps/x86_64/multiarch/scripts/gen-reg-macros.py
