RE: [r12-2640 Regression] FAIL: gcc.target/i386/dec-cmov-2.c scan-assembler-not test(l|q|w) on Linux/x86_64

[Committed] Tweak new test case gcc.target/i386/dec-cmov-2.c With -m32, this test case is sensitive to the instruction timings of the target (for ifcvt to normalize bar() to foo() during the ce1 pass, prior to the transformations actually being tested here). Specifying -march=core2 prevents

[PATCH] Optimize x ? bswap(x) : 0 in tree-ssa-phiopt

Many thanks again to Jakub Jelinek for a speedy fix for PR 101642. Interestingly, that test case "bswap16(x) ? : x" also reveals a missed optimization opportunity. The resulting "x ? bswap(x) : 0" can be further simplified to just bswap(x). Conveniently, tree-ssa-phiopt.c already

[committed] openmp: Handle OpenMP directives in attribute syntax in attribute-declaration

Hi! Now that we parse attribute-declaration (outside of functions), the following patch handles OpenMP directives in its attribute(s). What needs handling incrementally is diagnose mismatching begin/end pair like [[omp::directive (declare target)]]; int a; #pragma omp end declare target or
