OK.
Please also update cpuinfo.c from libgcc and corresponding
gcc.target/i386/builtin_target.c testcase.
Thanks,
Uros.

I will take a look to see if we share the same CPU detection code between
libgcc and config/i386/driver-i386.c.

I don't think it will bring any benefit, this is mainly one huge
switch statement that maps to different stuff in libgcc and
driver-i386.

libgcc and config/i386/driver-i386.c differ even before my patch.
I think we can do better.

Move cpuinfo.h from libgcc to common/config/i386 so that get_intel_cpu
can be shared by libgcc, GCC driver, gcc.target/i386/builtin_target.c
and libgfortran to detect the specific type of Intel CPU. Update
libgfortran to use has_cpu_feature to detect x86 CPU features.
Tested on Linux/x86 and Linux/x86-64. OK for master?
Thanks.

Subject: [PATCH] x86: Move cpuinfo.h from libgcc to common/config/i386
Move cpuinfo.h from libgcc to common/config/i386 so that get_intel_cpu
can be shared by libgcc, GCC driver, gcc.target/i386/builtin_target.c
and libgfortran to detect the specific type of Intel CPU. Update
libgfortran to use has_cpu_feature to detect x86 CPU features.
gcc/
* common/config/i386/cpuinfo.h: Moved from libgcc/config/i386.
(CHECK___builtin_cpu_is): New. Defined as empty if not defined.
(get_intel_cpu): Moved from libgcc/config/i386/cpuinfo.c. Add
an argument for AVX512VNNI. Use CHECK___builtin_cpu_is. Return
Intel CPU name.
(has_cpu_feature): New function.
* config/i386/driver-i386.c: Include
"common/config/i386/cpuinfo.h".
(host_detect_local_cpu): Call get_intel_cpu to get Intel CPU
name.
gcc/testsuite/
* gcc.target/i386/builtin_target.c: Include <stddef.h> and
../../../common/config/i386/cpuinfo.h.
(CHECK___builtin_cpu_is): New.
(inline): New. Defined as empty.
(check_intel_cpu_model): Removed.
(check_detailed): Call get_intel_cpu instead of
check_intel_cpu_model.
libgcc/
* config/i386/cpuinfo.h: Moved to ... gcc/common/config/i386.
* config/i386/cpuinfo.c: Include "common/config/i386/cpuinfo.h".
(__cpu_features2): Make it static in libgcc_s.so.1.
(get_intel_cpu): Moved to ... gcc/common/config/i386/cpuinfo.h.
(get_available_features): Always set __cpu_features2.
(__cpu_indicator_init): Call get_available_features before
calling get_intel_cpu. Pass has_cpu_feature (FEATURE_AVX512VNNI)
to get_intel_cpu.
libgfortran/
* m4/matmul.m4: Include <common/config/i386/cpuinfo.h> instead
of <config/i386/cpuinfo.h>. Use has_cpu_feature.
* generated/matmul_c10.c: Regenerated.
* generated/matmul_c16.c: Likewise.
* generated/matmul_c4.c: Likewise.
* generated/matmul_c8.c: Likewise.
* generated/matmul_i1.c: Likewise.
* generated/matmul_i16.c: Likewise.

Handling only Intel targets and not others is a sure way for patch to
be ignored.

Subject: [PATCH] x86: Move cpuinfo.h from libgcc to common/config/i386
Move cpuinfo.h from libgcc to common/config/i386 so that get_intel_cpu
can be shared by libgcc, GCC driver, gcc.target/i386/builtin_target.c
and libgfortran to detect the specific type of Intel and AMD CPUs. Use
the same enum processor_features in libgcc and x86 backend. Add static
assert to x86 backend to verify that libgcc and x86 backend are in sync.
Update processor feature check in in libgcc:
1. Update FEATURE_GFNI check to support SSE, AVX and AVX512 versions of
GFNI.
2. Add missing FEATURE_AVX512VP2INTERSECT.
3. Add FEATURE_XSAVEOPT, FEATURE_CLWB and FEATURE_CLZERO for get_amd_cpu.
4. Always set __cpu_features2 for has_cpu_feature.
Update libgfortran to use has_cpu_feature to detect x86 CPU features.

Huh... I didn't think the solution will be this messy... I have to
rethink the approach a bit.
Can you in the meantime please prepare a simple patch to fix the above
mentioned PRs and eventually backport it to other release branches? It
should be simple enough to be committed under obvious rule.
Thanks,
Uros.

That is what will happen when we have the same info in more than one place
There should only one place for CPU info.

Looking at the patch, it is clear that cpuinfo.c and driver-i386.c
should stay apart. They are two different things, and they are
orthogonal to each other; one can be updated without affecting the
other one. driver-i386.c handles way more targets than cpuinfo.c and
your patch only handles a subset of them. The unification does not
bring any benefit, it even complicates things more.
I think that unifying libgcc and i386-builtins.c is the way to go.
libgfortran should benefit from this unification, too.

There should one place to check a CPU feature, not 2. It can
be done with a proper cpuinfo.h.

libgfortran shouldn't include cpuinfo.h. It should use __builtin_cpu_is
and __builtin_cpu_supports.

This updated patch does it. It removes duplicated codes and
simplifies the implementation. With this patch, we just to update
a single place to add the new ISA support.

Here is the updated patch to add common/config/i386/cpuinfo-builtins.h.
SIZE_OF_CPU_FEATURES is now defined with CPU_FEATURE_MAX
so that we can simply just add a new feature to enum processor_features
and __cpu_features2 will have the correct size to cover all features.
fold_builtin_cpu is changed to work with any SIZE_OF_CPU_FEATURES
values.
Tested on Linux/x86-64 and Linux/x86. OK for master?
Thanks.

Subject: [PATCH] x86: Move cpuinfo.h from libgcc to common/config/i386
Move cpuinfo.h from libgcc to common/config/i386 so that get_intel_cpu
can be shared by libgcc, GCC driver and gcc.target/i386/builtin_target.c
to detect the specific type of Intel and AMD CPUs:
1. Use the same enum processor_features in libgcc and x86 backend.
2. Add more processor features to enum processor_features.
3. Add M_VENDOR, M_CPU_TYPE and M_CPU_SUBTYPE in i386-builtins.c to
avoid duplication in.
4. Use cpu_indicator_init, has_cpu_feature, get_amd_cpu and get_intel_cpu
in driver-i386.c and builtin_target.c.

Can you please add comment about the '32 + 32' and '32 + i * 32', it's unclear from the patch.
2) Can we remove all the:
> + unsigned int has_lahf_lm, has_sse4a;

...
if (arch)
{
const char *mmx = has_mmx ? " -mmmx" : " -mno-mmx";
const char *mmx3dnow = has_3dnow ? " -m3dnow" : " -mno-3dnow";
const char *sse = has_sse ? " -msse" : " -mno-sse";
...
options = concat (options, mmx, mmx3dnow, sse, sse2, sse3, ssse3,
sse4a, cx16, sahf, movbe, aes, sha, pclmul,
popcnt, abm, lwp, fma, fma4, xop, bmi, sgx, bmi2,
pconfig, wbnoinvd,
tbm, avx, avx2, sse4_2, sse4_1, lzcnt, rtm,
hle, rdrnd, f16c, fsgsbase, rdseed, prfchw, adx,

waitpkg, cldemote, ptwrite, avx512bf16, enqcmd,
avx512vp2intersect, serialize, tsxldtrk, NULL);
and instead mark flags in 'isa_names_table' that should be used for -match=native option emission.
We know names of the flags, their value (has_feature) and so we can generate that automatically?
3) Similarly we can we do automatically all the:
+ if (has_feature (FEATURE_AVX512VBMI2))
+ assert (__builtin_cpu_supports ("avx512vbmi2"));
We should have both information in 'isa_names_table'.
Thanks,
Martin

Subject: [PATCH] x86: Move cpuinfo.h from libgcc to common/config/i386
Move cpuinfo.h from libgcc to common/config/i386 and move isa_names_table
to common/config/i386 so that get_intel_cpu can be shared by libgcc, GCC
driver and gcc.target/i386/builtin_target.c to detect the specific type
of Intel and AMD CPUs:
1. Use the same enum processor_features in libgcc and x86 backend.
2. Add more processor features to enum processor_features.
3. Use the same isa_names_table in i386-builtins.c, driver-i386.c and
gcc.target/i386/builtin_target.c.
4. Use isa_names_table to generate ISA command-line options.
5. Use isa_names_table to generate __builtin_cpu_supports tests.
6. Add M_VENDOR, M_CPU_TYPE and M_CPU_SUBTYPE in i386-builtins.c to
avoid duplication in.
7. Use cpu_indicator_init, has_cpu_feature, get_amd_cpu and get_intel_cpu
in driver-i386.c and builtin_target.c.

Thank you for the updated patch.
I have still few nits:
1) I would make all the:

a macro. The local variable seems to superfluous.
2) can we automatically deduce option name:

I mean "-m" + "rdrnd" == "-mrdrnd" ?

Done.

The new option field serves 2 purposes:
1. Not all features have a corresponding command-line option
ISA_NAMES_TABLE_ENTRY("cmov", FEATURE_CMOV, P_ZERO, NULL)
for (i = 0; i < ARRAY_SIZE (isa_names_table); i++)
if (isa_names_table[i].option)
2. Some feature has a different name in the command-line option.
ISA_NAMES_TABLE_ENTRY("fxsave", FEATURE_FXSAVE, P_ZERO, "-mfxsr")
Here is the updated patch. OK for master?
Thanks.

Subject: [PATCH] x86: Move cpuinfo.h from libgcc to common/config/i386
Move cpuinfo.h from libgcc to common/config/i386 and move isa_names_table
to common/config/i386 so that get_intel_cpu can be shared by libgcc, GCC
driver and gcc.target/i386/builtin_target.c to detect the specific type
of Intel and AMD CPUs:
1. Use the same enum processor_features in libgcc and x86 backend.
2. Add more processor features to enum processor_features.
3. Use the same isa_names_table in i386-builtins.c, driver-i386.c and
gcc.target/i386/builtin_target.c.
4. Use isa_names_table to generate ISA command-line options.
5. Use isa_names_table to generate __builtin_cpu_supports tests.
6. Add M_VENDOR, M_CPU_TYPE and M_CPU_SUBTYPE in i386-builtins.c to
avoid duplication in.
7. Use cpu_indicator_init, has_cpu_feature, get_amd_cpu and get_intel_cpu
in driver-i386.c and builtin_target.c.

Yes, there are my objections.
As explained before, I support unifying libgcc and core gcc handling,
but _NOT_ unifying with driver-i386.c. Unifying libgcc and core gcc
handling would have benefit to avoid desynchronisation between the two
(which happened multiple times in the past, resulting in various API
issues). OTOH, unifying with driver-i386.c would result in quite messy
approach, because driver-i386 handles more targets beside relatively
recent 64bit Intel and AMD targets, not to mention heuristics to
determine the most appropriate target when standard detection fails
(e.g. emulators).

Only the duplicated parts of driver-i386.c should be unified. The only impact
should be removing code duplications. If it isn't the case, it is a bug in my
implementation.

Here is the updated patch to remove FEATURE_OSPKE and use bit_OSPKE
for FEATURE_PKU. It uses the same get_amd_cpu and get_intel_cpu in
libgcc and driver-i386.c:
a. Detect the processor name for newer Intel and AMD processors.
Since the older processor names are only supported by driver-i386.c,
not by libgcc, detection for the older processors remains in
driver-i386.c.
b. Detect available ISAs for all Intel and AMD processors.

Subject: [PATCH] x86: Move cpuinfo.h from libgcc to common/config/i386
There are x86 code duplications:
1. Both driver-i386.c and libgcc use CPUID to detect the processor name
as well as available ISAs. To detect the same processor or ISAs, the
same detection logic is duplicated in 2 places. Sometimes only one place
was up to date or got it right. Sometimes both places got it wrong.
2. Both x86 backend and libgcc define enum processor_features. libgcc
sets enum processor_feature and x86 backend checks enum processor_feature.
They are very easy out of sync and it has happened multiple times in the
past.
Move cpuinfo.h from libgcc to common/config/i386 and move isa_names_table
to common/config/i386 so that we can
1. Use the same get_amd_cpu and get_intel_cpu in libgcc and driver-i386.c:
a. Detect the processor name for newer Intel and AMD processors.
Since the older processor names are only supported by driver-i386.c,
not by libgcc, detection for the older processors remains in
driver-i386.c.
b. Detect available ISAs for all Intel and AMD processors.
2. Share the same enum processor_features and isa_names_table in x86
backend and libgcc.
This patch contains the following changes:
1. Use the same enum processor_features in libgcc and x86 backend.
2. Add more processor features to enum processor_features.
3. Use the same isa_names_table in i386-builtins.c, driver-i386.c and
gcc.target/i386/builtin_target.c.
4. Use isa_names_table to auto-generate ISA command-line options.
5. Use isa_names_table to auto-generate __builtin_cpu_supports tests.
6. Add M_VENDOR, M_CPU_TYPE and M_CPU_SUBTYPE in i386-builtins.c to
avoid duplication.
7. Use cpu_indicator_init, has_cpu_feature, get_amd_cpu and get_intel_cpu
in driver-i386.c and builtin_target.c.

Here is the updated patch for x86 backend and libgcc. driver-i386.c
is unchanged.
OK for master?
Thannks.
H.J.

Both x86 backend and libgcc define enum processor_features. libgcc sets
enum processor_feature and x86 backend checks enum processor_feature.
They are very easy out of sync and it has happened multiple times in the
past.
1. Move cpuinfo.h from libgcc to common/config/i386 so that we can share
the same enum processor_features in x86 backend and libgcc.
2. Change __cpu_features2 to an array to support more processor features.
3. Add more processor features to enum processor_features.

Thanks. We should change driver-i386.c very carefully and in an
independent way from this patch. It is a complex and interwoven web of
name, model and features check. I propose that we first convert
various has_xxx checks to a new interface, in as trivial way as
possible.

Yes, this part looks OK to me.
