--- Comment #3 from Vladimir Makarov <vmakarov at gcc dot gnu.org> --- (In reply to Andreas Krebbel from comment #0) > Created attachment 41383 [details] > Experimental patch Andreas, thank you for working on the issue. You are right. The hard reg in the clobber should be not be an earlyclobber one. But, unfortunately the patch is not fully correct. Static data exists in one examplar for insn with the same insn code and as consequence should not be dependent on other operands. I'll think about the correct solution. Do you have a test case? The patch might be ready soon after I get the test. Although it will take some time to test the patch.
