2017-11-17[ARM] Rework expectation for call to Armv8-M nonsecure functionThomas Preud'homme2-1/+6
Testcase gcc.target/arm/cmse/cmse-14.c checks whether bar is called via __gnu_cmse_nonsecure_call libcall and not via a direct call. However the pattern is a bit surprising in that it needs to explicitely allow "by" due to allowing anything before the 'b'. This patch rewrites the logic to look for b as a first non-whitespace letter followed iby anything (to match bl and conditional branches) followed by some spaces and then bar. 2017-11-17 Thomas Preud'homme <thomas.preudhomme@arm.com> gcc/testsuite/ * gcc.target/arm/cmse/cmse-14.c: Change logic to match branch instruction to bar.

2017-11-17[ARM] Fix selection of effective target for cmse testsThomas Preud'homme26-55/+39
Some of the tests in the gcc.target/arm/cmse directory (eg. gcc.target/arm/cmse/mainline/bitfield-4.c) are failing when run without an architecture specified in RUNTESTFLAGS due to them not adding the option to select an Armv8-M architecture. This patch fixes the issue by adding the right option from the exp file so that no architecture fiddling is necessary in the individual tests. 2017-11-17 Thomas Preud'homme <thomas.preudhomme@arm.com> gcc/testsuite/ * gcc.target/arm/cmse/cmse.exp: Add option to select Armv8-M Baseline or Armv8-M Mainline when running the respective tests. * gcc.target/arm/cmse/baseline/cmse-11.c: Remove architecture check and selection. * gcc.target/arm/cmse/baseline/cmse-13.c: Likewise. * gcc.target/arm/cmse/baseline/cmse-2.c: Likewise. * gcc.target/arm/cmse/baseline/cmse-6.c: Likewise. * gcc.target/arm/cmse/baseline/softfp.c: Likewise. * gcc.target/arm/cmse/mainline/hard-sp/cmse-13.c: Likewise. * gcc.target/arm/cmse/mainline/hard-sp/cmse-5.c: Likewise. * gcc.target/arm/cmse/mainline/hard-sp/cmse-7.c: Likewise. * gcc.target/arm/cmse/mainline/hard-sp/cmse-8.c: Likewise. * gcc.target/arm/cmse/mainline/hard/cmse-13.c: Likewise. * gcc.target/arm/cmse/mainline/hard/cmse-5.c: Likewise. * gcc.target/arm/cmse/mainline/hard/cmse-7.c: Likewise. * gcc.target/arm/cmse/mainline/hard/cmse-8.c: Likewise. * gcc.target/arm/cmse/mainline/soft/cmse-13.c: Likewise. * gcc.target/arm/cmse/mainline/soft/cmse-5.c: Likewise. * gcc.target/arm/cmse/mainline/soft/cmse-7.c: Likewise. * gcc.target/arm/cmse/mainline/soft/cmse-8.c: Likewise. * gcc.target/arm/cmse/mainline/softfp-sp/cmse-5.c: Likewise. * gcc.target/arm/cmse/mainline/softfp-sp/cmse-7.c: Likewise. * gcc.target/arm/cmse/mainline/softfp-sp/cmse-8.c: Likewise. * gcc.target/arm/cmse/mainline/softfp/cmse-13.c: Likewise. * gcc.target/arm/cmse/mainline/softfp/cmse-5.c: Likewise. * gcc.target/arm/cmse/mainline/softfp/cmse-7.c: Likewise. * gcc.target/arm/cmse/mainline/softfp/cmse-8.c: Likewise.

2017-11-17[ARM] Fix ICE in Armv8-M Security Extensions codeThomas Preud'homme2-1/+7
Commit r253825 which introduced some sanity checks for sbitmap revealed a bug in the conversion of cmse_nonsecure_entry_clear_before_return () to using bitmap structure. bitmap_and expects that the two bitmaps have the same length, yet the code in cmse_nonsecure_entry_clear_before_return () have different size for to_clear_bitmap and to_clear_arg_regs_bitmap, with the assumption that bitmap_and would behave has if the bits not allocated were in fact zero. This commit makes sure both bitmap are equally sized. 2017-11-17 Thomas Preud'homme <thomas.preudhomme@arm.com> gcc/ * config/arm/arm.c (cmse_nonsecure_entry_clear_before_return): Allocate to_clear_arg_regs_bitmap to the same size as to_clear_bitmap.

2017-11-16Add -std=c18 etc. option aliases.Joseph Myers7-4/+55
ISO C17 won't go to ballot until December, meaning publication of the standard won't be until 2018, leaving ambiguity as to whether people will end up referring to the standard as C17, as it's currently known and which corresponds to the __STDC_VERSION__ value, or C18 based on the publication date. In case people end up referring to this standard as C18, this patch adds corresponding option aliases -std=c18, -std=iso9899:2018, -std=gnu18 so people can use those names based on publication date if they wish. The "expected to be" explanations in help texts and the manual can be removed as and when the standard is published, hopefully before GCC 8 is out. Bootstrapped with no regressions on x86_64-pc-linux-gnu. gcc: * doc/invoke.texi (-std=c17): Refer to 2018 expected publication date of C17.

2017-11-16Canonicalize constant multiplies in divisionWilco Dijkstra4-11/+34
This patch implements some of the optimizations discussed in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71026. Canonicalize x / (C1 * y) into (x * C2) / y. This moves constant multiplies out of the RHS of a division in order to allow further simplifications (such as (C1 * x) / (C2 * y) -> (C3 * x) / y) and to enable more reciprocal CSEs. 2017-11-16 Wilco Dijkstra <wdijkstr@arm.com> Jackson Woodruff <jackson.woodruff@arm.com> gcc/ PR tree-optimization/71026 * match.pd: Canonicalize constant multiplies in division. gcc/testsuite/ PR tree-optimization/71026 * gcc.dg/cse_recip.c: New test.

2017-11-16Set default to -fomit-frame-pointerWilco Dijkstra38-196/+55
Almost all targets add an explict -fomit-frame-pointer in the target specific options. Rather than doing this in a target-specific way, do this in the generic options so it works identically across all targets. In many cases the target no longer needs to define TARGET_OPTION_OPTIMIZATION_TABLE, reducing the amount of target code. gcc/ * opts.c (default_options_table): Add OPT_fomit_frame_pointer entry. * common/config/alpha/alpha-common.c (TARGET_OPTION_OPTIMIZATION_TABLE): Remove OPT_fomit_frame_pointer entry. * common/config/arc/arc-common.c: Likewise. * common/config/arm/arm-common.c: Likewise. * common/config/avr/avr-common.c: Likewise. * common/config/c6x/c6x-common.c: Likewise. * common/config/cr16/cr16-common.c: Likewise. * common/config/cris/cris-common.c: Likewise. * common/config/epiphany/epiphany-common.c: Likewise. * common/config/fr30/fr30-common.c: Likewise. * common/config/frv/frv-common.c: Likewise. * common/config/ia64/ia64-common.c: Likewise. * common/config/iq2000/iq2000-common.c: Likewise. * common/config/lm32/lm32-common.c: Likewise. * common/config/m32r/m32r-common.c: Likewise. * common/config/mcore/mcore-common.c: Likewise. * common/config/microblaze/microblaze-common.c: Likewise. * common/config/mips/mips-common.c: Likewise. * common/config/mmix/mmix-common.c: Likewise. * common/config/mn10300/mn10300-common.c: Likewise. * common/config/nios2/nios2-common.c: Likewise. * common/config/pa/pa-common.c: Likewise. * common/config/pdp11/pdp11-common.c: Likewise. * common/config/powerpcspe/powerpcspe-common.c: Likewise. * common/config/riscv/riscv-common.c: Likewise. * common/config/rs6000/rs6000-common.c: Likewise. * common/config/rx/rx-common.c: Likewise. * common/config/s390/s390-common.c: Likewise. * common/config/sh/sh-common.c: Likewise. * common/config/sparc/sparc-common.c: Likewise. * common/config/tilegx/tilegx-common.c: Likewise. * common/config/tilepro/tilepro-common.c: Likewise. * common/config/v850/v850-common.c: Likewise. * common/config/visium/visium-common.c: Likewise. * common/config/xstormy16/xstormy16-common.c: Likewise. * common/config/xtensa/xtensa-common.c: Likewise. doc/ * invoke.texi (-fomit-frame-pointer): Update documentation.
