stdin/stdout on Windows; so add a new system function called
sys_setbinarymode which does it instead. Then find lots more binary mode
flags which need setting.
Our build enables assertions in some other ACK tools (like assemblers
and LLgen), but disabled them in ego until now. Bug #203 becomes a
failed assertion in ego's SR phase:
sr: util/ego/sr/sr_reduce.c:483: fix_header: Assertion
`INSTR(e) == ps_end' failed.
Comment out 2 assertions in util/ego/share, because they fail on
systems with 4-byte int, 8-byte long.
- In share/debug.c, undo my mistake in commit 9037d13 by changing
vfprintf back to fprintf in OUTTRACE.
- In ud/ud.c, move the trace output from stdout to stderr, because
stdout has ego's output file, which becomes opt2's input file. If
trace output goes to stdout, it gets prepended to the output file,
and opt2 errors with "wrong input file".
I also edit both build.lua files so ego depends on its header files;
this part isn't needed for -DTRACE.
One can now use -DTRACE by adding it to the cflags in both build.lua
files.
This needed lots of refactoring to ego --- not all platforms have ego descr
files, and ego will just crash if you invoke it without one. I think originally
it was never intended that these platforms would be used at -O2 or above.
Plats now only specify the ego descr file if they have one.
