Bug ID: 25917
Summary: findNeededSubprograms segfaults on compile units
without subprograms
Product: libraries
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Linker
Assignee: unassignedb...@nondot.org
Reporter: andrew.b.ad...@gmail.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
findNeededSubprograms in IRMover.cpp assumes that the CU->getSubprograms() is
not null and dereferences it, but it is null sometimes in my experience. This
probably happens when the compile unit has no subprograms.
Inserting:
if (!CU->getSubprograms()) continue;
just before the IRMover.cpp line 1196 fixes it for me
