Hi,
The stack-1.c testcase fails when being compiled for micromips with the -O0
optimization level. The reason is the testcase is expecting the following
sequence at the end of the function:
addiu $sp,$sp,16
jrc $31
But for micromips it generates the following:
jraddiusp 16
As the failure only happens at one optimization level I have decided to just
change the expected output rather than creating a separate micromips testcase.
I have tested this on the mips-mti-elf target using
mips32r2/{-mno-micromips/-mmicromips}
test options and there are no new regressions.
The patch and ChangeLog are below.
Ok to commit?
Many thanks,
Andrew

* gcc.target/mips/stack-1.c: Allow testcase to match jraddiusp
instruction.
