ones.

Precisely one stack hreg gets allocated for each vreg/congruence group for
...
eviction; this prevents us from having to worry about moving values from stack
slot to stack slot, which is hard.

MIPS appears to hate converting unsigneds to floats and vice versa.

The MIPS backend is still full of holes, and cut-and-pasted PowerPC code, but

is beginning to look like an actual code generator.

Change stdio to use atexit() rather than the internal __clean variable; this
...
breaks the dependency between exit/atexit and stdio. Buffers are no longer
flushed on abort() (because it's pretty risky). Move the relevant functions
into sys/core.

All the opendir()/readdir() stuff is obsolete because it's all implemented in
