This patch series adds support for the CMPBR extension. It includes the new `+cmpbr` option and rules to generate the new instructions when lowering conditional branches.
Testing done: `make bootstrap; make check` Karl Meakin (10): AArch64: place branch instruction rules together AArch64: reformat branch instruction rules AArch64: rename branch instruction rules AArch64: add constants for branch displacements AArch64: make `far_branch` attribute a boolean AArch64: recognize `+cmpbr` option AArch64: precommit test for CMPBR instructions AArch64: rules for CMPBR instructions AArch64: make rules for CBZ/TBZ higher priority Use HS/LO instead of CS/CC .../aarch64/aarch64-option-extensions.def | 2 + gcc/config/aarch64/aarch64-simd.md | 2 +- gcc/config/aarch64/aarch64-sme.md | 2 +- gcc/config/aarch64/aarch64.cc | 39 +- gcc/config/aarch64/aarch64.h | 3 + gcc/config/aarch64/aarch64.md | 564 ++++--- gcc/config/aarch64/iterators.md | 5 + gcc/config/aarch64/predicates.md | 15 + gcc/doc/invoke.texi | 3 + gcc/testsuite/gcc.target/aarch64/cmpbr.c | 1481 +++++++++++++++++ gcc/testsuite/lib/target-supports.exp | 14 +- 11 files changed, 1898 insertions(+), 232 deletions(-) create mode 100644 gcc/testsuite/gcc.target/aarch64/cmpbr.c -- 2.45.2
