2018-03-01[ARM] Fix copysign_softfloat_1.c option directivesThomas Preud'homme2-2/+6
gcc.target/arm/copysign_softfloat_1.c's use of arm_arch_v6t2 in dg-add-option changes the architecture to -march=armv6t2. Since the test only requires Thumb-2 capable architecture, we just need to add -mthumb on the command line since arm_thumb2_ok guarantees by definition that doing that is enough to select Thumb-2. This fixes warning on the command line when having -mcpu=cortex-m3 in RUNTESTFLAGS for instance. 2018-03-01 Thomas Preud'homme <thomas.preudhomme@arm.com gcc/testsuite/ * gcc.target/arm/copysign_softfloat_1.c: Remove dg-add-options and add -mthumb to the command-line.

2018-03-01Tighten use of HARD_FRAME_POINTER_REGNUM in alias.c (PR 84538)Richard Sandiford4-1/+46
RTL code needs to be consistent about whether it uses the stack pointer, the frame pointer or the argument pointer to access a given part of the frame. alias.c used this to divide accesses into three independent areas. The problem in the PR is that we did this for HARD_FRAME_POINTER_REGNUM even when the register wasn't being used as a frame pointer. We can't do that because the frame pointer is then just any old allocatable register and could certainly point to info accessed through the argument pointer or stack pointer. 2018-03-01 Richard Sandiford <richard.sandiford@linaro.org> gcc/ PR rtl-optimization/84538 * alias.c (init_alias_target): Add commentary.
