           Summary: Fix the atomicIncrement implementation for MIPS GCC
           Product: WebKit

          Platform: Unspecified

          Severity: Normal
          Priority: P2

After https://trac.webkit.org/changeset/139514 we need 32 and 64 bit implementation 
for atomicIncrement(). I fixed it in http://trac.webkit.org/changeset/139553, but
it seems __sync_add_and_fetch isn't supported by the MIPS GCC version. As far as
I know it should be supported from GCC 4.1. Is it possible if the MIPS bot has
an older GCC or __sync_add_and_fetch isn't supported on MIPS platform?
