f2f8e096f3 qfcc.h:
o	add a "freed" marker to def_t to prevent double freeing of
		temp def offsets

0a18c1256a Fix configure for zlib and static compiling. static compiling is still broken
But I'm sure taniwha is going to fix that shortly anyway :)

cb4ce6a634 remove the default label from the switch label table while fetching it. 2001-11-06 20:39:42 +00:00

ccbb1c3f04 document all those weird opcodes :) 2001-11-05 19:32:50 +00:00

13a177f217 use 'b' (bind) instead of '=' (assign) for switch's test temp def so simple
expressions (ie, just a def) don't generated wasted assignments and clean up
switch's debug info so you get the switch line rather than the line for the
closing }

9b784e331b remove '(' (never used, don't remember what it was intended for) and add
'b' (bind), 's' (state) and 'c' (call) to get_op_string.

5f5060cbf0 move the users and used setting code from emit_statement to
PR_AddStatementRef. This removes essentially duplicate code and 3 ifs :)

b499d7e1e8 I've decided that shuffling the `sections' like that doesn't really gain
anything, so I'm reverting that change.
2001-10-31 17:55:35 +00:00
Bill Currie
3b2d2a1c88 re-arrange the order of the `sections' of a .dat file to match the header
order. this also `happens' to put the strings section just before the globals
section (both at the end) which will make pointer bounds checking easier.

901a8ec9c5 qfcc: update man page. It's pretty useful, so I'll probably be setting
it up as part of the install for qfcc.

274ff6e59a Add getopt.h to the dist, just in case. 2001-10-26 23:54:20 +00:00
Jeff Teunissen
b07d60f6d6 add getopt.c and getopt1.c to the makefile. There is preprocessor
stuff in these files to detect when they need to be compiled, so they
don't need anything in configure.

5cbd50d835 count the number of digits needed rather than relying on -lm (now it's not
needed:)

f8a41cb1bc completely nuke the concept of "priority" from opcodes and use get_op_string
in emit_sub_expr instead of a redundant switch.

133ce647fb implement break and continue. only loops covered for now, but that's because
switch isn't implemented yet

237d238a65 beginnings of "if" uninitialized variable support. doesn't make any
difference yet

5ca785e7e8 uninitialized variable detection. not perfect (lots of false negatives, but
fewer than before;) but prozac isn't giving any false positives.
2001-10-18 20:05:26 +00:00

96e4e1a232 the beginning of unititialized var detection. first victim: functions.
--undefined-function-warning is now --no-undefined-function-warning and
the default is to detect called but undefined functions.
