How to add Loongson ISA for Mips target?
Hi LLVM developers,
GCC[1] is able to use Loongson ISA[2] for instruction selection:
$ cat hello.c
#include <stdio.h>
int main(int argc, char *argv[]) {
printf("Hello World\n");
return 0;
}
$ gcc -O0 -S hello.c
$ cat hello.s
.file 1 "hello.c"
.section .mdebug.abi64
.previous
.nan legacy
.gnu_attribute 4, 1
.abicalls

How to add Loongson ISA for Mips target?
...think you do not have to add a new subtarget. Take a
