Re: [PATCH] match.pd: Implement missed optimization (~X | Y) ^ X -> ~(X & Y) [PR109986]

[David Edelsohn via Gcc-patches]

Hi, Drew

Thanks for addressing this missed optimization.

The testcase includes an incorrect assumption: signed char, which
causes the testcase to fail on PowerPC.

Should the testcase be updated to specify signed char in the function
signatures or should -fsigned-char be added to the command line
options?

Thanks, David
