Bug ID: 26369
Summary: Link with libatomic for targets that don't support
atomic ops for all required sizes natively.
Product: libc++
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: All Bugs
Assignee: unassignedclangb...@nondot.org
Reporter: vasileios.kalinti...@imgtec.com
CC: llvm-bugs@lists.llvm.org, mclow.li...@gmail.com
Classification: Unclassified
There is a review request that fixes this at: http://reviews.llvm.org/D16613.
Without the patch that fixes the problem, the following regressions occur on
MIPS for the atomic tests:
