Bug ID: 28995
Summary: ARM SjLj exception handling assumes frame pointer is
r7
Product: libraries
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Backend: ARM
Assignee: unassignedb...@nondot.org
Reporter: oliver.stann...@arm.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
The ARM setjmp/longjmp exception handling assumes that the frame pointer
register is r7. This is not true for all targets, some use r11 instead.
It also assumes that a frame pointer is being used, but doesn't guarantee this.
We should probably emit a frame pointer for any function using the SjLj
intrinsics.
