[Qemu-devel] [PATCH] target/arm: Don't read r4 from v8M exception stackframe twice

2018-10-02 Thread Peter Maydell
A cut-and-paste error meant we were reading r4 from the v8M callee-saves exception stack frame twice. This is harmless since it just meant we did two memory accesses to the same location, but it's unnecessary. Delete it. Signed-off-by: Peter Maydell --- target/arm/helper.c | 1 - 1 file changed,
