[committed] Fix pr69535

We stripped a paradoxical subreg, whose unspecified bits had been masked by an AND. Combine converted that into a ZERO_EXTRACT, but in the narrower mode. The end of make_compound_operation deals with mode mismatches by creating another paradoxical subreg. However, this time the unspecified bi

[PATCH] gcc: invoke: delete -mno-fma4 docs

We don't document the -mno-xxx variants for other flags here, and the paragraph here specifically says "Each has a corresponding -mno- option to disable use of these instructions". Drop the -mno-fma4 line. 2016-01-31 Mike Frysinger * doc/invoke.texi: Delete -mno-fma4. --- gcc/doc/inv

Jason, Do you have any further comments on the changes to the test or is it okay to check it? https://gcc.gnu.org/ml/gcc-patches/2016-01/msg02245.html In light of the powerpc64le behavior I did not make any changes to verify the no-op VLA initialization does not in fact write into the space a

[committed] Fix declaration of vsscanf on hpux

The attached hack fixes missing const from the first argument of the declararation for vsscanf on hpux. This has been present forever. sscanf is correctly declared, so I presume this is a typo. I limited the fix to hpux since stage3 is over. Tested on hppa2.0w-hp-hpux11.11. Committed to trunk

Re: [RS6000] ABI_V4 init of toc section

This is the more comprehensive fix for PR68662, the one I'm a little nervous about applying during stage4. OK for when stage1 opens? Applying this patch makes https://gcc.gnu.org/ml/gcc-patches/2016-01/msg02325.html redundant, but I'm inclined to leave it in: Not initializing the toc symbol at fi

[RS6000] lqarx and stqcx. registers

lqarx RT and stqcx. RS are valid only with even numbered gprs. The predicate to enforce this happens to allow a loophole, closed by this patch. This pattern created by combine: Trying 8 -> 9: Successfully matched this instruction: (set (subreg:PTI (reg:TI 155 [ D.2357 ]) 0) (unspec_volatile:P

The comment says this test is supposed to prevent "a narrower operation than requested", but it actually only allows a larger subreg, not one the same size. Fix that. Bootstrapped and regression tested powerpc64-linux. OK for stage1? Note that this bug was found when investigating why gcc-6 doe

C++ PATCH for c++/68763 (ICE in verify_unstripped_args)

The problem in this testcase is that the C++ front end modifies the TYPE_PURPOSE of TYPE_ARG_TYPES after a function type has been created and added to the hash table, so a later creation of an equivalent function type won't necessarily find the earlier type. Usually this just means extra copie

C++ PATCH for c++/69009 (ICE with partial specialization of variable template)

In this testcase, instantiate_decl was trying to look up an instantiation of a partial specialization using the arguments for the partial specialization on the primary template, which finds a different instance of the template. Fixed by reconstructing the arguments to the primary template. T

C++ PATCHes for abi_tag bugs

These patches fix a couple of abi_tag bugs that were reported to me recently. The first is an issue whereby all instantiations of a class template were sharing tags, so instantiating a template with a tagged type argument would apply the tag to another instantiation. Oops. The second is an
