-Subject: [PATCH] better detection of broken -fzero-call-used-regs
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-gcc 13.2.0 on ppc64le refuses to compile some function, including
-cipher.c:compression_alg_list() with an error:
-
-> sorry, unimplemented: argument ‘used’ is not supportedcw
-> for ‘-fzero-call-used-regs’ on this target
-
-This extends the autoconf will-it-work test with a similarly-
-structured function that seems to catch this.
