FYI: Now that I got my .init section straightened out with a patch to
GCC I was able to use qemu to test mips16. 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.
