- Authentication-results: sourceware.org; auth=none
Hello,
this patch adds a new powerpc64le.inc file appropriate for the
ELFv2 ABI and uses it to support the asm-source.exp test case
on powerpc64le (which previously resulted in UNTESTED).
Tested on powerpc64le-linux.
Pushed to mainline.
Bye,
Ulrich
ChangeLog:
* gdb.asm/asm-source.exp: Handle powerpc64le-* targets.
* gdb.asm/powerpc64le.inc: New file.
