Subject: [PATCH 00/11] aarch64 GCS preliminary patches
Date: Tue, 22 Aug 2023 11:38:05 +0100 [thread overview]
Message-ID: <cover.1692699125.git.szabolcs.nagy@arm.com> (raw)
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.
GCS support will depend on the linux ABI that is under discussion at
https://lore.kernel.org/lkml/20230807-arm64-gcs-v4-0-68cfa37f9069@kernel.org/
so it will come later.
Richard Sandiford (1):
Handle epilogues that contain jumps
Szabolcs Nagy (10):
aarch64: AARCH64_ISA_RCPC was defined twice
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: Fix pac-ret eh_return tests
aarch64: Disable branch-protection for pcs tests
aarch64,arm: Remove accepted_branch_protection_string
aarch64,arm: Fix branch-protection= parsing
aarch64: Fix branch-protection error message tests
aarch64,arm: Move branch-protection data to targets
