Bug #: 14371
Summary: Regression: InstCombine alloca->global optimization
crashes on opaque types
Product: libraries
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW
Severity: release blocker
Priority: P
Component: Scalar Optimizations
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
Classification: Unclassified
Created attachment 9561
--> http://llvm.org/bugs/attachment.cgi?id=9561
test case
Please see the attached test case: In getPointeeAlignment(), InstCombine
assumes that DataLayout::getABITypeAlignment always works on
PT->getElementType(). However, if the type is opaque, this is not the case.
I marked the report as »release blocker« since this is a regression from 3.1
and breaks the LDC compiler. Sorry if this is not the intended use case.
