2018-04-11[ARM] Fix PR85261: ICE with FPSCR setter builtinThomas Preud'homme4-4/+19
Instruction pattern for setting the FPSCR expects the input value to be in a register. However, __builtin_arm_set_fpscr expander does not ensure that this is the case and as a result GCC ICEs when the builtin is called with a constant literal. This commit fixes the builtin to force the input value into a register. It also remove the unneeded volatile in the existing fpscr test and fixes the function prototype. 2018-04-11 Thomas Preud'homme <thomas.preudhomme@arm.com> gcc/ PR target/85261 * config/arm/arm-builtins.c (arm_expand_builtin): Force input operand into register. gcc/testsuite/ PR target/85261 * config/arm/arm-builtins.c (arm_expand_builtin): Force input operand into register.

It also tidies some surrounding code.

2018-04-10rs6000: Enable -fasynchronous-unwind-tables by defaultSegher Boessenkool7-4/+25
To find out where on-entry register values live at any point in a program, GDB currently tries to parse to parse the executable code. This does not work very well, for example it gets confused if some accesses to the stack use the frame pointer (r31) and some use the stack pointer (r1). A symptom is that backtraces can be cut short. This patch enables -fasynchronous-unwind-tables by default for rs6000, which causes us to emit DWARF unwind tables for all functions, solving these problems. This not do anything for sub-targets without DWARF, and only for ELF sub-targets for now. It increases executable size, but only modestly, and does not change memory use, only the disk image. * common/config/rs6000/rs6000-common.c (rs6000_option_init_struct): Enable -fasynchronous-unwind-tables by default if OBJECT_FORMAT_ELF. gcc/testsuite/ * gcc.target/powerpc/dfmode_off.c: Add -fno-asynchronous-unwind-tables. * gcc.target/powerpc/dimode_off.c: Ditto. * gcc.target/powerpc/tfmode_off.c: Ditto. * gcc.target/powerpc/timode_off.c: Ditto.
