Hi Kyrill,
PR rtl-optimization/67481 is a testsuite regression on sparc-solaris that
Rainer reported. I haven't tested
that this patch fixes that, but I suspect that the root cause is the
same. Rainer, could you please
check that this fixes the regression for you?
I've now checked that with your patch the regression went away indeed,
using a limited non-bootstrap build on sparc-sun-solaris2.10. Next I'll
run a full bootstrap to check there are no other issues.
After some more benchmarking I've noticed that this patch is overly restrictive
in some cases. I have a prototype patch that fixes the regressions and does not
restrict if-conversion too much.
I need to do some more testing, and hope to post it in due time.
Sorry for the noise.
Kyrill
Thanks.
Rainer
