aarch64 GCS preliminary patches | expand

Message

Szabolcs Nagy Nov. 3, 2023, 3:36 p.m. UTC

I'm working on Guarded Control Stack support for aarch64 and have a
set of patches that are needed for GCS but seem useful without it so
makes sense to review them separately from the rest of the GCS work.

previous version:
https://gcc.gnu.org/pipermail/gcc-patches/2023-August/628123.html

Szabolcs Nagy (7):
  aarch64: Use br instead of ret for eh_return
  aarch64: Do not force a stack frame for EH returns
  aarch64: Add eh_return compile tests
  aarch64: Disable branch-protection for pcs tests
  aarch64,arm: Remove accepted_branch_protection_string
  aarch64,arm: Fix branch-protection= parsing
  aarch64,arm: Move branch-protection data to targets
