2015-10-05Remove REAL_VALUE_FROM_CONST_DOUBLERichard Sandiford55-443/+294
To maintain symmetry after the previous removal of CONST_DOUBLE_FROM_REAL_VALUE, this patch also gets rid of REAL_VALUE_FROM_CONST_DOUBLE. All the macro did was copy the contents of CONST_DOUBLE_REAL_VALUE into a temporary real_value structure. In many cases there was no need for this temporary and we could simply use the CONST_DOUBLE_REAL_VALUE directly. For that reason this patch is less automatic than the others. Bootstrapped & regression-tested on x86_64-linux-gnu. Also tested by building one target per CPU directory and checking that there were no new warnings and no changes in testsuite output at -O2. gcc/ * real.h (REAL_VALUE_FROM_CONST_DOUBLE): Delete. * config/aarch64/aarch64.c (aarch64_float_const_zero_rtx_p) (aarch64_print_operand, aarch64_float_const_representable_p) (aarch64_output_simd_mov_immediate): Use CONST_DOUBLE_REAL_VALUE instead of REAL_VALUE_FROM_CONST_DOUBLE. * config/arc/arc.c (arc_print_operand): Likewise. * config/arm/arm.c (arm_const_double_rtx, vfp3_const_double_index) (neon_valid_immediate, arm_print_operand, arm_emit_fp16_const) (vfp3_const_double_for_fract_bits, vfp3_const_double_for_bits): Likewise. * config/arm/arm.md (*arm32_movhf, consttable_4, consttable_8) (consttable_16): Likewise. * config/arm/vfp.md (*movhf_vfp_neon, *movhf_vfp): Likewise. * config/avr/avr.c (avr_print_operand): Likewise. * config/bfin/bfin.md: Likewise (in a define_split). * config/c6x/c6x.md: Likewise (in a define_split). * config/cr16/cr16.c (cr16_const_double_ok): Likewise.

2015-10-05Replace REAL_VALUES_EQUAL with real_equalRichard Sandiford30-72/+146
Richard B suggested we should replace dconsthalf etc. with dconst<1, 2> (). When I tried that, the extra comma caused problems with some lingering uses of the old target macros for handling reals (e.g. REAL_ARITHMETIC instead of real_arithmetic), since the constant was then treated as two macro parameters. It would have been possible to add an extra level of brackets to avoid this, but I thought I might as well take the opportunity to remove the macros instead. (Note that I'm only removing macros that caused a problem directly, or are closely related to ones that did.) This first patch replaces REAL_VALUES_EQUAL with a real_equal function. The prototype is the same as for real_identical, which has already undergone a half-transition in this direction. Bootstrapped & regression-tested on x86_64-linux-gnu.

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.
