2023-04-03target/arm: Fix generated code for cpreg reads when HSTR is activePeter Maydell
In commit 049edada we added some code to handle HSTR_EL2 traps, which we did as an inline "conditionally branch over a gen_exception_insn()". Unfortunately this fails to take account of the fact that gen_exception_insn() will set s->base.is_jmp to DISAS_NORETURN. That means that at the end of the TB we won't generate the necessary code to handle the "branched over the trap and continued normal execution" codepath. The result is that the TCG main loop thinks that we stopped execution of the TB due to a situation that only happens when icount is enabled, and hits an assertion. Explicitly set is_jmp back to DISAS_NEXT so we generate the correct code for when execution continues past this insn. Note that this only happens for cpreg reads; writes will call gen_lookup_tb() which generates a valid end-of-TB.

2023-04-03target/arm: Fix non-TCG build failure by inlining pauth_ptr_mask()Philippe Mathieu-Daudé
aarch64_gdb_get_pauth_reg() -- although disabled since commit 5787d17a42 ("target/arm: Don't advertise aarch64-pauth.xml to gdb") is still compiled in. It calls pauth_ptr_mask() which is located in target/arm/tcg/pauth_helper.c, a TCG specific helper.

2023-03-21target/arm: Don't advertise aarch64-pauth.xml to gdbPeter Maydell
Unfortunately a bug in older versions of gdb means that they will crash if QEMU sends them the aarch64-pauth.xml. This bug is fixed in gdb commit 1ba3a3222039eb25, and there are plans to backport that to affected gdb release branches, but since the bug affects gdb 9 through 12 it is very widely deployed (for instance by distros). It is not currently clear what the best way to deal with this is; it has been proposed to define a new XML feature name that old gdb will ignore but newer gdb can handle. Since QEMU's 8.0 release is imminent and at least one of our CI runners is now falling over this, disable the pauth XML for the moment. We can follow up with a more considered fix either in time for 8.0 or else for the 8.1 release. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
