jyu2 updated this revision to Diff 309067.
jyu2 retitled this revision from "Fix missing error for use of 128-bit integer
inside SPIR64 device code." to "[CLANG] Fix missing error for use of 128-bit
integer inside SPIR64 device code.".
jyu2 added a comment.
Fix problem with @jdoerfert pointed where using bool hasInt128Type() const
override { return false; } instead.
