[Qemu-devel] [PULL 09/10] Revert "target/aarch64: optimize indirect branches"

[Richard Henderson]

This reverts commit e75449a346bf558296966a44277bfd93412c6da6.

This patch appears to induce lockups, or maybe livelocks, while
booting a Linux kernel.  The assumption is that there is a bug
elsewhere within QEMU, but reverting the patch allows normal work
to continue in the meantime.
