Sorry about that, fixed in
r15-855-g4fcdc37e8856bde847d3b8dd2915b68d56ad1d62 . Just was a
testcase issue really.

RE: Regressions on native/master at commit r16-29 vs commit r16-21 on Linux/x86_64
I have a fix for the testcases. Just need to increase the size from 32 to 1024.
Basically with 32, vectors are used for the memcpy which allows to optimize it;
just differently and not what is being tested here. I am hoping 1024 is big
enough not to hit another target which does memcpy for 1024 bytes with one
register load/store.
I will push a fix tomorrow.
Thanks,
Andrew

I have a fix for this testcase and the other one already. Will commit it
tomorrow. It is just a testcase issue as the testcase gets optimized
correctly; just in a different way than what this patch expects.

This is already fixed with
r15-7898-gd71139982a364c5c9646737a7b9a407967ecd88c . Sorry for
forgetting to update these testcases too.

This is just an extra inlining which causes pcom to happen twice now.
Will look into fix that this coming week.

The coroutines failures might be a front-end issue or a testcase issue
dealing with operator new.

The specifics_1 failure is a front-end bug which is being fixed:
