            Bug ID: 26711
           Summary: clang -Oz miscompiles gmp
           Product: new-bugs
           Version: 3.8
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: new bugs
          Assignee: unassignedbugs at nondot.org
          Reporter: bero at linaro.org
                CC: llvm-bugs at lists.llvm.org
    Classification: Unclassified

Building gmp 6.1.0 with clang -Oz results in failures (crashes) during "make
check".
clang -Os and clang -O2 are ok.

This is with clang 3.8 (branches/release_38 svn as of yesterday).
