From: Benjamin Gray Date: Tue, 26 Mar 2024 04:44:20 +0000 (+1100) Subject: powerpc: Error on assembly warnings X-Git-Tag: v6.10-rc1~129^2~73 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=608d4a5ca56302181e669cea0aa571cbec6680eb;p=thirdparty%2Fkernel%2Flinux.git powerpc: Error on assembly warnings We currently enable -Werror on the arch/powerpc subtree. However this only catches C warnings. Assembly warnings are logged, but the make invocation will still succeed. This can allow incorrect syntax such as ori r3, r4, r5 to be compiled without catching that the assembler is treating r5 as the immediate value 5. To prevent this in assembly files and inline assembly, add the -fatal-warnings option to assembler invocations.
