I ran the entire GCC testsuite with -mips16 and the only failure I saw that didn't look familiar to me was: FAIL: gcc.c-torture/execute/ieee/compare-fp-1.c compilation, -O2 -flto -fuse-linker-plugin -fno-fat-lto-objects This is a segfault coming from the linker, I haven't investigated it anymore then that yet, but in general the testing looks very good now.
