/var/tmp//ccGMk41W.s: Assembler messages:
/var/tmp//ccGMk41W.s:201: Warning: Use of 'mov' may violate WAW dependency
'GR%, % in 1 - 127' (impliedf), specific resource number is 18
/var/tmp//ccGMk41W.s:201: Warning: Only the first path encountering the
conflict is reported
/var/tmp//ccGMk41W.s:200: Warning: This is the location of the conflicting
usage
It looks like this is PR 36898. The warning is bogus in the sense that there
is no real WAW dependency conflict but the assembler isn't able to figure that
out on it's own without some help with better .pred.rel.mutex lines from the
compiler.
