Bug ID: 63360
Summary: Does not retore f31 at -O0 across function calls
Product: gcc
Version: 4.9.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org

Created attachment 33551

invert.c, invert.cpp, and invert.gdb gdb session
Register variable stored in f31 is stored on the stack, but not restored and
thus clobbered, after a function call.
Compiled with
gcc -c -g -Wall -fsigned-char -Wno-unused-but-set-variable -pipe -g -mlongcall
