Summary: Assert in TargetLowering::SimplifySetCC when using
intergers >= 256 bits
Product: libraries
Version: trunk
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: P2
Component: Common Code Generator Code
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
TargetLowering::SimplifySetCC seems to assume that operands can fit inside an
uint64_t. If you write a program that has large integer types (256 or larger
in my case) this causes an assertion. I don't see any reason why APInt can't
be used instead of uint64_t in this situation. I wrote a patch that appears to
work, but I haven't put it through extensive testing.
