: [PATCH] Disable -fuse-caller-save when -pg is active
Patch has been tested with DejaGnu gcc test suite on mips32r2 cross
compiler and bootstrapped and tested on
x86_64 native compiler.
Thanks for finishing up the testing. Would you like me to check this in for
you?
Please do. My recollection

I have managed to reproduce the problem on the small test case on mips32, but
the test is architecture independent and should probably fail on many other
ports without

Right, but we can test the existence of the expander via the HAVE_xxx
interface.
What that can't test is the expander failing (via FAIL;). But the

Which ones, HAVE_prologue?

A problem is detected with building Linux kernel on MIPS platform when
both -fuse-caller-save and -pg options are present. The reason for this
is that -fuse-caller-save relies on the analysis of RTL code, but when
profiling is active (with -pg option) the code is instrumented
by adding a call to

I use prologue/epilogue to emit rtl in my port. I’d like this optimization to
kick on in my port, as we do explain everything

We don’t support fprintf prologues anymore, they were removed years ago.
Did we ever get all the ports converted?
Ah… sorry, I was wrong. We merely hookized it and the tm.h interface is gone.
