This patch is exactly along the same lines as a previous one to check for SSE/SSE2 support in the assembler: http://gcc.gnu.org/ml/gcc-patches/2010-05/msg01276.html Why would one accept the former and reject the corresponding runtime tests of the latter? And where do you see actual complexity? The beef of the patch is concentrated in two files (sol2-check.h and fpu-387.h) and a single function call (sol2_check).

I originally meant to test in check_effective_target_sse{, 2} if the current test is an execution test and only then perform the sse runtime check. Unfortunately, it doesn't seem to be possible to do this check reliably (if at all). On the other hand, the only tests that need to be modified by adding the sse*_runtime effective-target keyword are those that don't use sse*-check.h. Rainer

This patch is OK, but please commit it without sse{,2}_runtime changes. Please prepare another incremental patch that includes sse{,2}_runtime stuff, we will discuss your approach separatelly.

Fine, thanks. > Please prepare another incremental patch that includes sse{,2}_runtime > stuff, we will discuss your approach separatelly. Ok. To be honest, H.J.'s suggestion to use sse*-check.h as far as possible, while more invasive, is certainly attractive since we need only a single mechanism everywhere (well, with the exception of the few *.exp files that decide whether or not to add -msse2 on x86). This way, nobody needs to worry about the sse*_runtime stuff in individual testcases. Rainer

Not on Solaris 8 or older Solaris 9. E.g. on S8, -march=native passes
-march=k8-sse3, which may break.
Will have a look, thanks.

"H.J. Lu" <hjl.tools@gmail.com> writes: > If your OS doesn't support SSE, but -march=native may generate SSE > instructions, then you get a big problem. Well, only if you use -march=native ;-) It's obviously the same problem addressed by this patch: the presence of SSE support in the CPU is not enough to decide if the insns can actually be used. Same solution, obviously. Rainer

I don't think this makes sense: by the same logic, gcc would forbid to create 64-bit code if the system running the compiler isn't capable of executing the resulting code. Rainer

My first attempts to build mainline for Solaris 8/9 x86 have just been using the Solaris 8 and 9 assemblers on Solaris 11. While a couple of problems could be sorted out this way, actually bootstrapping found a couple of others. The most pressing one is that before Solaris 9 4/04, the Solaris kernel doesn't save and restore SSE and SSE2 registers, so any attempt to execute SSE/SSE2 instructions causes the program to receive SIGILL, even if the CPU supports the insns: Solaris/IA32 should save/restore SSE/SSE2 register set on context switch http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=4783204 To avoid the problem, I globally default -march to pentiumpro on Solaris 8 and 9, not only for Solaris 8 with Sun as as in this patch: http://gcc.gnu.org/ml/gcc-patches/2010-05/msg01267.html but there are still two areas that must be fixed because they use SSE/SSE2 instructions regardless: * libgfortran determines if the CPU is capable of executing SSE instructions at runtime and uses them if so. This check is not enough and caused all Fortran exectution tests both in gcc/testsuite/gfortran.* and libgomp to fail. * Similarly, the SSE/SSE2/SSE3 testcases in gcc.target/i386 use the same technique (cf. gcc.target/sse{, 2, 3}-check.h), and fail the same way. Unfortunately, this problem cannot easily be detected at runtime, as would be possible on Solaris 10+ with getisax(2), but we need to set up a signal handler, try some instruction, and act accordingly. Unfortunately, this is more involved than it may seem at first: you cannot simply return from a SIGILL handler after setting some flag variable, since the faulting instruction will be executed again, leading to an infinite loop. My solution was inspired by the way GNU libsigsegv handles SEGV: they return from the signal handler with setcontext(2). I can do the same here, provided I set set PC to the next instruction after the faulting one. Therefore, I need to know exact insn lengths and preferably use insns with side effects that don't hurt. The meat of the patch which implements this can be found in libgfortran/config/fpu-387.h and gcc.target/i386/sol2-check.h. The former takes care of libgfortran, the latter of all tests using sse-check{, 2, 3}.h. For the few remaining testcases that hardcode -msse or -msse2, I need some new effective-target keywords: sse for the ability to compile/assemble sse insns, sse_runtime and sse2_runtime for the ability to execute them. With this in place, I've been able to reduce testsuite failures from ca. 13000 to just a handful. There will a few unrelated followup patches that bring Solaris 8/9 x86 testsuite results practically en par with Solaris 10 and 11. Bootstrapped without regressions on i386-pc-solaris2.{8, 9, 10, 11}, both with Sun as and GNU as. At the moment, the 4.5 branch is broken on Solaris 8/9 x86, since it won't even bootstrap without --with-arch=pentiumpro on Solaris 8 and 9, which is a regression from 4.4. Like this patch http://gcc.gnu.org/ml/gcc-patches/2010-05/msg01276.html I'd like to backport the current one to the 4.4 and 4.5 branches after some soak time on mainline. Ok for mainline now and the 4.4 and 4.5 branches later?
