I noticed that gcc.dg/vect/slp-multitypes-2.c is failing on Solaris 8/x86 with Sun as:
FAIL: gcc.dg/vect/slp-multitypes-2.c (test for excess errors) WARNING: gcc.dg/vect/slp-multitypes-2.c compilation failed to produce executable Excess errors: Assembler: slp-multitypes-2.c "/var/tmp//ccmA7WBi.s", line 16 : Illegal mnemonic "/var/tmp//ccmA7WBi.s", line 16 : Syntax error unpcklpd %xmm0,%xmm2 This should be dealt with by the explicit check_vect_support_and_set_flags in vect.exp, which does } elseif { [istarget "i?86-*-*"] || [istarget "x86_64-*-*"] } { lappend DEFAULT_VECTCFLAGS "-msse2" if { [check_effective_target_sse2_runtime] } { set dg-do-what-default run } else { set dg-do-what-default compile } Unfortunately, this gets overridden by the explicit /* { dg-do run { xfail { sparc*-*-* && ilp32 } } } PR rtl-opt /46603 */ To fix this, I've changed the testcase to use dg-xfail-run-if instead. Besides, I see the failure only with gas, not Sun as. The following patch has been tested with the appropriate runtest invocations on both i386-pc-solaris2.8 and sparc-sun-solaris2.10 (both as and gas). I'm about to commit this to mainline. The 4.5 branch is unaffected, but 4.6 is. Ok there, too, after testing? Thanks.
