How to add Loongson ISA for Mips target?
...ad to for MIPS32r6 to deal with the instruction removals).
I would recommend the ASE_* classes which are intended for application specific extensions. These are used for optional extensions to the MIPS ISA such as MSA or DSP, but are also used for vendor specific extensions to the MIPS ISA such as cnMIPS. The ASE_CNMIPS class and the Proc<"octeon", ...> record are good examples that show how Cavium's extensions to the MIPS ISA were included.

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
