Apparently Windows doesn't have strndup or index.

Don't use '-' in option string to getopt().
...
Using '-' might fail on platforms like FreeBSD. Commit 50a7031

'!' tracing is now always emitted; tracing goes to stderr.

Various bits of cleanup; we should almost be ready to try sending this to the

assembler soon...

Oops, forgot to add the output option spec to the string!

Refactored the way hops are rendered; add support for emitting code (although
...
with no prologue or epilogue yet).

Overhaul of everything phi related; critical edge splitting now happens before
...
anything SSA happens; liveness calculations now look like they might be
working.

Allowing an input filename on the command line makes debuggers happy. (Then we
...
don't need to redirect stdin.)

Fix the horror of the startup code; now uses getopt and stuff and the debug
...
flags can be set as an option.

Perform SSA conversion of locals. Much, *much* better code now, at least
...
inasmuch as it looks better before register allocation. Basic blocks now know
their own successors and predecessors (after a certain point in the IR
processing).

Move fatal(), warning() and aprintf() into the new data module (because they're

really useful).

Fleshed out hops and vregs. The result is almost looking like code now ---
...
uncanny.

Procedure compilation now happens after the entire EM file has been read in (so
...
that we can look inside data blocks which might be defined in the future...
sigh, csa and csb). csa and csb no longer generate invalid IR.

Replaced the block splicer with a trivial block eliminator (which rewrites
...
jumps to blocks which contain only a jump). Don't bother storing the bb graph
in the ir nodes; we can find it on demand by walking the tree instead ---
slower, but much easier to understand and more robust. Added a terrible map
library.

Add a bodged in algorithm for converting basic block communication from stacked

variables to SSA. Also add dead block removal and block splicing. IR code is
much better now.
