gcc.dg/tree-ssa/sra-12.c is skipped on a bunch of targets, including AArch64, because the default max-scalarization-size depends on MOVE_RATIO, and on those targets thus ends up being too small for SRA to optimize the testcase. Recently I noticed that the test has been failing for some time on ARM too. This patch fixes the test on ARM, AArch64, avr, and sh, and by extension I believe also on nds32, although I haven't managed to build a nds32 compiler to check.There is an argument that instead we should skip the test on ARM too; or rather, since at least ARM and AArch64 would like the test to pass, we should xfail it on those platforms until we have time to experiment with the threshold/param for SRA. I hope to do some more investigation on that front as part of (or followup to) PR/63679. Is this OK for trunk? Cheers, Alan gcc/testsuite/ChangeLog: * gcc.dg/tree-ssa/sra-12.c: Enable test on all targets; add --param sra-max-scalarization-size-Ospeed.
OK. jeff
