2019-12-05Fix g++.dg/torture/pr59226.CJan Hubicka2-1/+6
this patch fixes ICE in g++.dg/torture/pr59226.C which was triggered by new comdat_local sanity check. What happens here is that function gets inlined into its own thunk which makes it !comdat_local_p but the updating code does not notice since thunk calls comdat local alias of the function itself and we look at alias target rather than original callee. This also shows that we miss optimization here. Currently we will not inline thunk out of its comdat local group w/o inlining function it is associated with into it. We should teach inline_call to reoslve edges to aliases while inlining and relax calls_comdat_local flag. But this needs bit more work, so I fix the ICE first. * ipa-inline-transform.c (inline_call): Fix maintenatnce of comdat_local From-SVN: r279021

2019-12-04Fix C handling of use of lvalues of incomplete types (PR c/36941, PR c/88827).Joseph Myers14-35/+146
Bug 88827 points out that GCC should not be rejecting C code that dereferences a pointer to an incomplete type in the case that uses &* to take the address of the resulting lvalue, because no constraint is violated in that case (other than for C90 when the incomplete type is unqualified void, which we already handle correctly) and as the lvalue never gets converted to an rvalue there is no undefined behavior either. This means that the diagnostic for such a dereference is bogus and should be removed; if the lvalue gets converted to an rvalue, there should be an appropriate error later for the use of the incomplete type. In most cases, there is, but bug 36941 points out the lack of a diagnostic when the incomplete (non-void) type gets cast to void (where a diagnostic seems appropriate for this undefined behavior as a matter of quality of implementation). This patch removes the bogus diagnostic (and C_TYPE_ERROR_REPORTED which was only used in the code that is removed - only that one, bogus diagnostic had this duplicate suppression, not any of the other, more legitimate diagnostics for use of incomplete types) and makes convert_lvalue_to_rvalue call require_complete_type for arguments not of void types, so that all relevant code paths (possibly except some for ObjC) get incomplete types diagnosed. It's possible that this makes some other checks for incomplete types obsolete, but no attempt is made to remove any such checks. Bootstrapped with no regressions for x86_64-pc-linux-gnu.

2019-12-04[ARM] Improve max_cond_insns setting for Cortex coresWilco Dijkstra2-0/+10
To enable cores to use the correct max_cond_insns setting, use the core-specific tuning when a CPU/tune is selected unless -mrestrict-it is explicitly set. On Cortex-A57 this gives 1.1% performance gain on SPECINT2006 as well as a 0.4% codesize reduction. gcc/ * config/arm/arm.c (arm_option_override_internal): Use max_cond_insns from CPU tuning unless -mrestrict-it is used.

2019-12-04Fix VIEW_CONVERT_EXPRs for VECTOR_BOOLEAN_TYPE_PsRichard Sandiford4-69/+271
In r278410 I added code to handle VIEW_CONVERT_EXPRs between variable-length vectors. This included support for decoding a VECTOR_BOOLEAN_TYPE_P with subbyte elements. However, it turns out that we were already mishandling such bool vectors for fixed-length vectors: we treated each element as a stand-alone byte instead of putting multiple elements into the same byte. I think in principle this could have been an issue for AVX512 as well. This patch adds encoding support for boolean vectors and reuses a version of the new decode support for fixed-length vectors. 2019-12-04 Richard Sandiford <richard.sandiford@arm.com> gcc/ * fold-const.c (native_encode_vector_part): Handle VECTOR_BOOLEAN_TYPE_Ps that have subbyte precision.
