2015-10-04Fix fortran common-related error recovery ICE.Mikael Morin5-7/+37
Upon reverting a symbol in a common block (after throwing an error), the compiler was ICEing because the symbol's common_block field was set, but the symbol was not in the common block's list of symbols. Fixed by both adding the symbol to the common block list and setting the symbol's common_block field at the same time. Furthermore, the gfc_add_in_common call is delayed and its result is ignored, so that its error messages are ignored and the compiler has the opportunity to give a better error message. Another gfc_add_in_common call is added later during resolution to emit again the missing errors.

2015-10-02[AArch64] Use default_elf_asm_named_section instead of special cased hookRamana Radhakrishnan2-74/+5
Hi, The hook for TARGET_ASM_NAMED_SECTION was defined separately in the backend around the time frame for GCC 4.7 under the assumption that '@' would be used as a comment character in the binutils port. This was indeed true in versions of the AArch64 port that never made it into the FSF tree. However this practice was killed before the binutils port made it upstream. Doing archaeology into various revisions including the first commit of upstream binutils, talking to Marcus about the history of this and actually testing the first commit of binutils, I can confidently say that the upstream binutils port never had any use of '@' as a comment character for AArch64 However we never got rid of the special cased handling in GCC and the duplication of code in the AArch64 backend. This was found when I was playing with Virtual Table verification on ARM and AArch64 and discovered ICEs which were similar but manifested in different places begging the obvious question. Tested on aarch64-none-elf with no regressions. Ok to apply ? Ramana 2015-10-02 Ramana Radhakrishnan <ramana.radhakrishnan@arm.com> * config/aarch64/aarch64.c (aarch64_elf_asm_named_section): Delete.

2015-10-02rs6000: Add "cannot_copy" attribute, use it (PR67788, PR67789)Segher Boessenkool5-2/+73
After the shrink-wrapping patches the prologue will often be pushed "deeper" into the function, which in turn means the software trace cache pass will more often want to duplicate the basic block containing the prologue. This caused failures for 32-bit SVR4 with -msecure-plt PIC. This configuration uses the load_toc_v4_PIC_1 instruction, which creates assembler labels without using the normal machinery for that. If now the compiler decides to duplicate the insn, it will emit the same label twice. Boom. It isn't so easy to fix this to use labels the compiler knows about (let alone test that properly). Instead, this patch wires up a "cannot_copy" attribute to be used by TARGET_CANNOT_COPY_P, and sets that attribute on these insns we do not want copied. 2015-10-01 Segher Boessenkool <segher@kernel.crashing.org> PR target/67788 PR target/67789 * config/rs6000/rs6000.c (TARGET_CANNOT_COPY_INSN_P): New.
