Summary: opt crash - Illegal Instruction
Product: libraries
Version: trunk
Platform: Macintosh
OS/Version: MacOS X
Status: NEW
Severity: normal
Priority: P2
Component: Scalar Optimizations
AssignedTo: unassignedbugs at nondot.org
ReportedBy: dpatel at apple.com
Bugpoint produced this while trying to reduce test case for
Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_PROTECTION_FAILURE at address: 0x00000010
0x035ce798 in llvm::isInstructionTriviallyDead (I=0xcb0e0e0) at Local.cpp:328
328 if (!I->mayWriteToMemory()) return true;
I am not sure this smaller test cause produces same crash or not. But in any case it causes Illegal
Instruction
