Re: RFA: PR target/53120, constraint modifier "+" on operand tied by matching-constraint, "0".


Hi DJ,
Make sure a match_dup will still match the generated pattern later,
I've had problems with match_dup not matching two rtx that
rtx_equals() says are "the same" but not physically the same.

I have tried, but failed, to find a way to trigger the use of the bset_qi pattern. :-( I tried rebuilding the toolchain and running the GCC testsuite, but neither of these worked. Do you have a test case that triggers it ?


Cheers
  Nick
