This patchset fixes some bugs in our SME-related signal frame handling for linux-user:
* we need to make the equivalent change to a recent kernel bugfix/ABI change: TPIDR2_EL0 should be cleared when delivering a signal * we forgot the TPIDR2_MAGIC signal frame record (which is necessary for SME v1) * we forgot the ZT_MAGIC signal frame record when implementing SME2 These bugs generally only surface when guest code attempts to unwind an exception from inside a signal handler and SME is involved. Discovered (and the fixes tested) by some new gcc test cases which implement their part of the bugfix/ABI change https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=b5ffc8e75a8 thanks -- PMM Peter Maydell (3): linux-user/aarch64: Clear TPIDR2_EL0 when delivering signals linux-user/aarch64: Support TPIDR2_MAGIC signal frame record linux-user/aarch64: Support ZT_MAGIC signal frame record linux-user/aarch64/signal.c | 142 +++++++++++++++++++++++++++++++++++- 1 file changed, 140 insertions(+), 2 deletions(-) -- 2.43.0
