[PATCH] D39074: [libunwind][MIPS]: Add support for unwinding in N32 processes.

sdardis added a comment.

Um, I now appear to be getting different results for running under QEMU doing it the proper way. I was previously rebuilding the failing test by hand and running under qemu. I don't believe I changed anything important, I'll have to take a longer look.

If you define an Executor for libunwind you can run the testsuite under QEMU, automagically.

I have:

  LIBUNWIND_EXECUTOR               PrefixExecutor(['/home/sdardis/bin/qemu-mipsn32.sh'],LocalExecutor())

/home/sdardis/bin/qemu-mips32.sh for is a simple bash script:

  #!/bin/bash
  ~/mips-mti-linux-gnu/2016.05-06/bin/qemu-mipsn32 -L /home/snd-local/mips-mti-linux-gnu/2016.05-06/sysroot/mips-r2-hard/ -E LD_LIBRARY_PATH=/home/snd-local/mips-mti-linux-gnu/2016.05-06/mips-mti-linux-gnu/lib/mips-r2-hard/lib32/ "$@"

Hope this helps.

Thanks for all the work you're putting into this.
