2020-12-15i386: Fix up -march=x86-64-v[234] vs. target attribute [PR98274]Jakub Jelinek2-7/+15
The following testcase fails to compile. The problem is that when ix86_option_override_internal is called the first time for command line, it sees -mtune= wasn't present on the command line and so as fallback sets ix86_tune_string to ix86_arch_string value ("x86-64-v2"), but ix86_tune_specified is false, so we don't find the tuning in the table but don't error on it. When processing the target attribute, ix86_tune_string is what it was earlier left with, but this time ix86_tune_specified is true and so we error on it. The following patch does what is done already e.g. for "x86-64" march, in particular default the tuning to "generic". 2020-12-15 Jakub Jelinek <jakub@redhat.com> PR target/98274 * config/i386/i386-options.c (ix86_option_override_internal): Set ix86_tune_string to "generic" even when it wasn't specified and ix86_arch_string is "x86-64-v2", "x86-64-v3" or "x86-64-v4".

2020-12-15i386: Make -march=x86-64-v[234] behave more like other -march= optionsJakub Jelinek12-23/+47
If somebody has -march=x86-64-v2 (or -v3 or -v4) in $CFLAGS, $CXXFLAGS etc., then -m32 or -mabi=ms stops working. What is worse, if one configures gcc --with-arch-64=x86-64-v2 (or -v3 or -v4), then -mabi=ms stops working. I think that is a nightmare user experience. It is ok that x86-64-v[234] behave slightly different from other -march= options (in that they imply unless overridden -mtune=generic rather then -mtune= equal to the -march argument), but the error when one mixes it with -mabi=ms, or -m32 doesn't improve anything. It is true that the exact option set is only defined in the x86-64 psABI (IMHO that is a mistake too, we should copy that into the GCC documentation like we document it for any other -march= option), but there is no reason why that exact set of CPU features can't be used for other ABIs, it is just a set of CPU features. If we add micro-architecture levels to the 32-bit ABI (I doubt anyone wants to do that, but just hypothetically), then those micro-architecture levels wouldn't certainly be called x86-64-v* but perhaps i386-v*. In the tests, __GCC_HAVE_SYNC_COMPARE_AND_SWAP_16 can't be expected on -m32 not because the CPU feature wouldn't be set, but because the instruction is 64-bit only and 32-bit code doesn't have __int128 etc. support. 2020-12-15 Jakub Jelinek <jakub@redhat.com> * config/i386/i386-options.c (ix86_option_override_internal): Don't error on -march=x86-64-v[234] with -m32 or -mabi=ms. * config.gcc: Don't reject --with-arch=x86-64-v[234] or --with-arch_32=x86-64-v[234]. * doc/invoke.texi (-march=x86-64-v[234]): Document what the option does for other ABIs. * gcc.target/i386/x86-64-v2.c: Don't expect __GCC_HAVE_SYNC_COMPARE_AND_SWAP_16 to be defined with -m32. * gcc.target/i386/x86-64-v2-other.c: New test. * gcc.target/i386/x86-64-v2-msabi.c: New test. * gcc.target/i386/x86-64-v3.c: Fix a comment pasto.

The validating code didn't allow --with-cpu=native, so explicitly allow that.
