[Qemu-devel] [Bug 1328996] Re: [AArch64] - blr x30 is handled incorrectly

[Peter Maydell]

I think this should already be fixed in master by commit 1b505f93bcf60
(about a month ago). Can you try a newer QEMU build, please?

Title:
  [AArch64] - blr x30 is handled incorrectly

Status in QEMU:
  New

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.
