Title:
[AArch64] - blr x30 is handled incorrectly
Status in QEMU:
Fix Committed
Bug description:
Whenever x30 is used as the operand for blr, the result will be
incorrect. There is no restriction on using x30 (LR) with the blr
instruction in the ARMv8 manual. There are two statically linked
64-bit executables in files.tar.gz: good and bad. The executable
"good" uses "blr x9", and the output is what is expected: "func". The
executable "bad" uses "blr x30" and nothing is printed out. It prints
"func" on the actual device.
