i386: Mark Xeon Phi ISAs as deprecated
Checks
Commit Message
Since Knight Landing and Knight Mill microarchitectures are EOL, we
would like to remove its support in GCC 15. In GCC 14, we will first
emit a warning for the usage.
gcc/ChangeLog:
* config/i386/driver-i386.cc (host_detect_local_cpu):
Do not append "-mno-" for Xeon Phi ISAs.
* config/i386/i386-options.cc (ix86_option_override_internal):
Emit a warning for KNL/KNM targets.
* config/i386/i386.opt: Emit a warning for Xeon Phi ISAs.

I think it's better to keep supporting -mtune/arch=knl without diagnostics
but simply not enable the ISAs we don't support. The better question is
what to do about KNL specific intrinsics headers / intrinsics? Will we
simply remove those?

I see, it could be a choice and might be better. But if we take this, how should
we define -mtune=knl remains a question.

If there is no objection, The intrinsics are planned to be removed in GCC 15.
As far as concerned, almost nobody are using them with the latest GCC. And
there is no complaint when removing them in ICC/ICX.

I'd say mapping it to a "close" micro-architecture makes most sense, but
we could also simply keep the tuning entry for knl?

I see. Replacing the header contents with #error "XYZ is no longer supported"
might be nicer. OTOH x86intrin.h should simply no longer include them.

Actually I have written a removal test patch, one of the issue might be there is
something specific about knl in tuning for VZEROUPPER, which is also reflected in
PR82990.
/* X86_TUNE_EMIT_VZEROUPPER: This enables vzeroupper instruction insertion
before a transfer of control flow out of the function. */
DEF_TUNE (X86_TUNE_EMIT_VZEROUPPER, "emit_vzeroupper", ~m_KNL)
If we chose to keep them, this behavior will be changed.

That is nicer. I will take that in GCC 15 patch.

We usually promise backwards compatibility with respect to accepted options
which is why we have things like
ftree-vect-loop-version
Common Ignore
Does nothing. Preserved for backward compatibility.
the backend errors on unknown march/tune and that would be a regression
for build systems using that (even if that's indeed very unlikely). That's why
I suggested to make it still do something (doing "nothing", aka keeping generic
is probably worse than dropping). I guess having -march=knl behave differently
is also bad so I guess there's not a good solution for that.
So - just to have made the above point, I'm fine with what x86 maintainers
decide here.
