Date: Fri, 02 Feb 2024 18:21:44 +0000 From: Jiaxun Yang <jiaxun.yang@...goat.com> To: Thomas Bogendoerfer <tsbogend@...ha.franken.de>, Nathan Chancellor <nathan@...nel.org>, Nick Desaulniers <ndesaulniers@...gle.com>, Bill Wendling <morbo@...gle.com>, Justin Stitt <justinstitt@...gle.com> Cc: linux-mips@...r.kernel.org, linux-kernel@...r.kernel.org, llvm@...ts.linux.dev, Jiaxun Yang <jiaxun.yang@...goat.com> Subject: [PATCH 5/8] MIPS: Loongson64: test for -march=loongson3a cflag Currently march flag is hardcoded to loongson3a for GCC and mips64r2 for clang. We can actually test it to simplify the code.
