This patch adds helper functions that say which of the two modes involved in a subreg is the larger, preferring the outer mode in the event of a tie. It also converts IRA and reload to track modes instead of byte sizes, since this is slightly more convenient when variable-sized modes are added later. 2017-10-26 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * rtl.h (wider_subreg_mode): New function. * ira.h (ira_sort_regnos_for_alter_reg): Take a machine_mode * rather than an unsigned int *. * ira-color.c (regno_max_ref_width): Replace with...

2017-10-26Introduce emit_frame_chainWilco Dijkstra3-12/+25
The current frame code combines the separate concepts of a frame chain (saving old FP,LR in a record and pointing new FP to it) and a frame pointer used to access locals. Add emit_frame_chain to the aarch64_frame descriptor and use it in the prolog and epilog code. For now just initialize it as before, so generated code is identical. Also correctly set EXIT_IGNORE_STACK. The current AArch64 epilog code restores SP from FP if alloca is used. If a frame pointer is used but there is no alloca, SP must remain valid for the epilog to work correctly. gcc/ * config/aarch64/aarch64.h (EXIT_IGNORE_STACK): Set if alloca is used. (aarch64_frame): Add emit_frame_chain boolean. * config/aarch64/aarch64.c (aarch64_frame_pointer_required) Move eh_return case to aarch64_layout_frame.

2017-10-26Simplify frame layout for stack probingWilco Dijkstra2-16/+17
This patch makes some changes to the frame layout in order to simplify stack probing. We want to use the save of LR as a probe in any non-leaf function. With shrinkwrapping we may only save LR before a call, so it is useful to define a fixed location in the callee-saves. So force LR at the bottom of the callee-saves even with -fomit-frame-pointer. Also remove a rarely used frame layout that saves the callee-saves first with -fomit-frame-pointer. Doing so allows the store of LR to be used as a valid stack probe in all frames. gcc/ * config/aarch64/aarch64.c (aarch64_layout_frame): Ensure LR is always stored at the bottom of the callee-saves. Remove rarely used frame layout which saves callee-saves at top of frame, so the store of LR can be used as a valid probe in all cases. From-SVN: r254112
2017-10-26Improve addressing of TI/TFmodeWilco Dijkstra4-4/+35
In https://gcc.gnu.org/ml/gcc-patches/2017-06/msg01125.html Jiong pointed out some addressing inefficiencies due to a recent change in regcprop (https://gcc.gnu.org/ml/gcc-patches/2017-04/msg00775.html). This patch improves aarch64_legitimize_address_displacement to split unaligned offsets of TImode and TFmode accesses. The resulting code is better and no longer relies on the original regcprop optimization. For the test we now produce: add x1, sp, 4 stp xzr, xzr, [x1, 24] rather than: mov x1, sp add x1, x1, 28 stp xzr, xzr, [x1] gcc/ * config/aarch64/aarch64.c (aarch64_legitimize_address_displacement): Improve unaligned TImode/TFmode base/offset split. testsuite/ * gcc.target/aarch64/ldp_stp_unaligned_2.c: New file.
