Subject: LoongArch: define preprocessing macros "__loongarch_{arch,tune}"
X-Git-Tag: basepoints/gcc-15~6473
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f095da2c5a452df7a7e184e0dcb5bb1538dd9086;p=thirdparty%2Fgcc.git

LoongArch: define preprocessing macros "__loongarch_{arch,tune}"

These are exported according to the LoongArch Toolchain Conventions[1]
as a replacement of the obsolete "_LOONGARCH_{ARCH,TUNE}" macros,
which are expanded to strings representing the actual architecture
and microarchitecture of the target.

	"__loongarch_{arch,tune}" in the preprocessor.
