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
Reporter: camm at debian dot org
Created attachment 33551
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=33551&action=edit
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
