  The patch series add loongarch32 and ilp32 abi support to gcc. One can
build libgcc, libatomic and glibc etc and generate a complete
loongarch32-unknown-linux-gnu-toolchain with minimal patches at:

- binutils: https://github.com/jiegec/binutils-gdb/tree/loongarch32
- glibc: https://github.com/jiegec/glibc/tree/loongarch32
- crosstool-ng: https://github.com/jiegec/crosstool-ng/tree/loongarch32

We will wait for folks at Loongson to complete abi documentation of
ilp32d abi.

Changes since v1:

- Can build a complete toolchain with glibc
- Fix sizeof(long double) in ilp32 abi
- Fix ftintrz generation for loongarch32
