[SimplifyLibCalls] Add dereferenceable bytes from known callsites
...
Summary:
int mm(char *a, char *b) {
return memcmp(a,b,16);
}
Currently:
define dso_local i32 @mm(i8* nocapture readonly %a, i8* nocapture readonly %b) local_unnamed_addr #1 {
entry:
%call = tail call i32 @memcmp(i8* %a, i8* %b, i64 16)
ret i32 %call
}
After patch:
define dso_local i32 @mm(i8* nocapture readonly %a, i8* nocapture readonly %b) local_unnamed_addr #1 {
entry:
%call = tail call i32 @memcmp(i8* dereferenceable(16) %a, i8* dereferenceable(16) %b, i64 16)
ret i32 %call
}

...
The reversion apparently deleted the test/Transforms directory.
Will be re-reverting again.

Temporarily Revert "Add basic loop fusion pass."
...
As it's causing some bot failures (and per request from kbarton).
This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda.

Enable simplify libcalls for ARM PCS
...
Teach SimplifyLibcalls that in can treat functions annotated with
apcs, aapcs or aapcs_vfp like normal C functions if they only take
and return integer or pointer values, and the target is not iOS.
