2016-05-20Add -mgeneral-regs-only optionH.J. Lu15-2/+193
X86 Linux kernel is compiled only with integer instructions. Currently, -mno-sse -mno-mmx -mno-sse2 -mno-3dnow -mno-avx -mno-80387 -mno-fp-ret-in-387 -mskip-rax-setup is used to compile kernel. If we add another non-integer feature, it has to be turned off. We can add a -mgeneral-regs-only option, similar to AArch64, to disable all non-integer features so that kernel doesn't need a long list and the same option will work for future compilers. It can also be used to compile interrupt handler. gcc/ PR target/70738 * common/config/i386/i386-common.c (OPTION_MASK_ISA_GENERAL_REGS_ONLY_UNSET): New.

2016-05-20This patch adds support for the signed and unsigned int versions of the...Bill Seurer6-1/+330
This patch adds support for the signed and unsigned int versions of the vec_addec altivec builtins from the Power Architecture 64-Bit ELF V2 ABI OpenPOWER ABI for Linux Supplement (16 July 2015 Version 1.1). There are many of the builtins that are missing and this is part of a series of patches to add them. There aren't instructions for the int versions of vec_addec so the output code is built from other built-ins that do have instructions which in this case is the following. vec_addec (va, vb, carryv) == vec_or (vec_addc (va, vb), vec_addc(vec_add(va, vb), vec_and (carryv, 0x1))) The new test cases are executable tests which verify that the generated code produces expected values. C macros were used so that the same test case could be used for both the signed and unsigned versions. An extra executable test case is also included to ensure that the modified support for the __int128 versions of vec_addec is not broken. The same test case could not be used for both int and __int128 because of some differences in loading and storing the vectors. Bootstrapped and tested on powerpc64le-unknown-linux-gnu and powerpc64-unknown-linux-gnu with no regressions. Is this ok for trunk?

2016-05-19PR c/71171: Fix uninitialized source_range in c_parser_postfix_expressionDavid Malcolm4-37/+61
A common way for a c_expr to have an uninitialized src_range is in error-handling, where the "value" field is set to error_mark_node without touching the src_range, leading to complaints from valgrind. This patch introduces a new method c_expr::set_error which sets the value to error_mark_node whilst initializing the src_range to UNKNOWN_LOCATION. This fixes the valgrind issue seen in PR c/71171, along with various other related issues seen when running the testsuite using the checker patch I posted here: https://gcc.gnu.org/ml/gcc-patches/2015-12/msg00887.html (this checker still doesn't fully work yet, but it seems to be good for easily detecting these issues without needing Valgrind). gcc/c/ChangeLog: PR c/71171 * c-parser.c (c_parser_generic_selection): Use c_expr::set_error in error-handling.
