From: dann frazier <dann.frazier@canonical.com>
Some Linux distributions are experimenting with builds that target a
higher x86-64 psABI, such as x86-64-v3. To avoid inheriting these
compiler defaults in edk2 builds, and therefore breaking compatibility
with machines using older CPUs, explicitly target the generic x86-64
psABI. This is similar to how we explicitly specify the cpu type for
some other architectures (-march=i586 for IA32, -march=armv7-a for ARM).
Spot tested with OVMF builds using GCC5 and CLANG38.

-=-=-=-=-=-=-=-=-=-=-=-Ping on this. Would it be more palatable if I limited the change only to tested toolchains (gcc/clang)? Alternatively, is there a way to submit this code to CI to verify the !(gcc|clang) variants? -dann On Fri, Jun 10, 2022 at 12:09:18PM -0600, dann frazier wrote: > From: dann frazier <dann.frazier@canonical.com> > > Some Linux distributions are experimenting with builds that target a > higher x86-64 psABI, such as x86-64-v3.

This may be a strong opinion but I would consider toolchains that explicitly change the default -march from the well understood x86-64 (which all 64-bit processors support) to be totally broken. If a distro wants to switch the -march for the packages, override CFLAGS :) On Wed, Jun 29, 2022 at 10:57 PM dann frazier <dann.frazier@canonical.com> wrote: > Ping on this.

GCC 5.4 documentation ( https://gcc.gnu.org/onlinedocs/gcc-5.4.0/gcc/x86-Options.html#x86-Options) doesn't include x86-64. I assume that specific option was added somewhere in the last 2-3 years when this x86-64-v* concept was added? I went looking around in linux and they don't seem to specify anything of sorts either. I can't speak for ARM but for IA32 it's pretty logic: the Pentium 1 (i586) was the first processor with CPUID, RDTSC, RD/WRMSR, etc. Essentials for firmware code that will never really even run on a processor that old.

Hi Pedro, Yeah, apparently GCC didn't document it until 8.1.0: https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=c7cb6c178884 But it appears to have been introduced far earlier - best I can tell, in 4.1: https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=3fec9fa9b726 It seems to be unrelated to the introduction of x86-64-v*, which was in 11.1: https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=324bec558e95 I don't speak GCC source fluently, so it's possible I could've misinterpreted those commits, so I did some testing. Ubuntu 16.04 had compilers based on GCC 5.4.0 and clang 4.0.
