2020-05-06c++: QT overload regression with attribute [PR94946]Nathan Sidwell3-3/+18

2020-05-06x86: Fix vextract* masked patterns [PR93069]Jakub Jelinek3-213/+256
The AVX512F documentation clearly states that in instructions where the destination is a memory only merging-masking is possible, not zero-masking, and the assembler enforces that. The testcase in this patch fails to assemble because of Error: unsupported masking for `vextracti32x8' on vextracti32x8 $0x0, %zmm1, -64(%rsp){%k1}{z} For the vector extraction patterns, we apparently have 7 *_maskm patterns that only accept memory destinations and rtx_equal_p merge-masking source for it, 7 *<mask_name> corresponding patterns that allow memory destination only for the non-masked cases (through <store_mask_constraint>), then 2 *<mask_name> patterns (lo ssehalf V16FI and lo ssehalf VI8F_256 ones) which do allow memory destination even for masked cases and are the cause of the testsuite failure, because we must not allow C constraint if the destination is m, and finally one pair of patterns (separate * and *_mask, hi ssehalf VI4F_256), which has another issue (for which I don't have a testcase though), where if it would match zero-masking with register destination, it wouldn't emit the needed {z} into assembly. The attached patch fixes those 3 issues only, perhaps more suitable for backporting. But, even with that fixed, we are missing 3 further *_maskm patterns and more importantly, I find the split into 3 separate patterns after subst, *_maskm for masking with memory destination, *_mask for masking with register destination and * for non-masking unnecessarily complex and harder for reload, so the included patch below (non-attached) instead kills all *_maskm patterns and splits the *<mask_name> patterns into * and *_mask by hand instead of subst, where the *_mask ones make sure that with v destination they use 0C, while with m destination they use 0 and as condition enforce that either destination is not MEM, or rtx_equal_p between the destination and corresponding merging-masking operand source. If we had those 3 missing *_maskm patterns, this patch would actually result in both shorter sse.md and shorter machine description after subst (e.g. length of tmp-mddump.md), as we don't have them, the patch is actually 16 lines longer sse.md, but still shorter tmp-mddump.md. 2020-05-06 Jakub Jelinek <jakub@redhat.com> PR target/93069 * config/i386/subst.md (store_mask_constraint, store_mask_predicate): Remove.

This version of the fix uses __getauxval instead of getauxval. The whole thing is guarded simply on __gnu_linux__. __getauxval was introduced in 2.16 but the aarch64 port was added in 2.17 so in practice I expect all aarch64 glibcs to support __getauxval.

2020-05-06tree-optimization/94963 - avoid bogus uninit warning with store-motionRichard Biener4-7/+59
Eliding the load for store-motion causes an uninitialized variable flowing into the loop, conditionally initialized and used. The uninit warning cannot relate the flag used to guard the initialization and use with the actual initialization so the following robustifies the previous approach of marking the conditional store as not to be warned on by instead initializing the variable on loop entry from an uninitialized variable we mark as not to be warned for. 2020-05-06 Richard Biener <rguenther@suse.de> PR tree-optimization/94963 * tree-ssa-loop-im.c (execute_sm_if_changed): Remove no-warning marking of the conditional store.

2020-05-06doc: Update install.texi for GCC 10 on SolarisRainer Orth2-35/+68
This patch updates install.texi for GCC 10 on Solaris. It includes some general cleanup and updates and includes a couple of caveats, some of them found when testing GCC 10.1.0 RC1 with only the bundled tools. The reference to TGCware on the binaries page is gone because they only provide binaries up to Solaris 9. The note about configuring 64-bit Solaris/SPARC compilers with --build=sparcv9-sun-solaris2.11 became necessary because upstream config.guess silently reverted my patch to automatically detect this. We already had a bug report about a comparison failure caused by this issue.

Per clarification in [1], macro is supposed to check for partial clobbering of single HW registers. Since PRU declares only 8-bit HW registers, and ABI does not define individual bit clobbering, it is safe to remove the implementation.

2020-05-05PRU: Fix R3.w0 register classDimitar Dimitrov5-9/+27
TI has clarified [1] that R3.w0 is caller saved, so allow compiler to use it. This is safe change because older GCC versions treat R3.w0 as fixed register and never use it.
