Michael Kuperstein <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|RESOLVED |REOPENED Resolution|FIXED |--- --- Comment #8 from Michael Kuperstein <[email protected]> --- Some of the regressions in eembc were fixed, but others still remain. There are two remaining issues I can see: 1) Easy: isNonEscapingGlobalNoAlias(), for the "load from global variable" case, does not call GetUnderlyingObject() on the pointer operand. This means it misses cases where the load is from a GEP/BitCast ConstantExpr based on a GV. 2) Harder: this is tangentially related to PR22475. The canonicalization from r226781 produces inttoptr casts that isNonEscapingGlobalNoAlias() can't (and probably shouldn't try to) look through. I think the fix for this should be on the InstCombine end, not GMR. -- You are receiving this mail because: You are on the CC list for the bug.
