Hi,
RTL-based forward propagation pass shouldn't propagate hard register.
OK for trunk?
Thanks.

Ok.
Hi,
the attached patch fixes the remaining cases of handling input that
ends in EOF instead of a normal separator for list formatted read of
the primitive types. Ok for trunk and 4.6?

The patch reduces the difference between the cfi-asm and non-cfi-asm

done producing the CFI insns we need, another pass ove

Hi,
PR 49495 is actually a bug in the verifier that does not look through
aliases at one point. Fixed wit the patch below (created a special
function, otherwise I just wasn't able to fit the 80 column limit).
Bootstrapped and tested on x86_64-linux. OK for trunk?
Thanks,
Martin
