Bill Currie 55cc0f9206 Bring back the unsigned type (PROGS version bump)
This is only low-level support (the unsigned keyword still does not work),
but sufficient to make switch statements using jump tables work.
2011-04-09 10:07:47 +09:00
Bill Currie 8e18c76bde Make initialized variables defs rather than immediate constants. 2011-03-30 19:58:09 +09:00
Bill Currie dc7a78b2ff Fix case label type conversions.
The previous method made too many assumptions.
2011-03-06 11:41:01 +09:00
Bill Currie 28f4de94d2 Fix switch statements so the work in the new scheme.
Convert case labels to be the same type as the switch expression.
Use alias expressions for the various test expressions.

Bill Currie a281033920 Alais the jump table's array to an integer.
As per the previous commit, I'm not sure this is the right thing to do, but
it works for now.

Bill Currie b5e7e666e9 Fix some missed branch/goto expression changes. 2011-03-03 17:33:53 +09:00
Bill Currie c5ecc170b6 Give labels a usage count to detect unused labels. 2011-03-03 15:28:49 +09:00
Bill Currie fff4fc693e Fix value hashing and comparison in switch expressions. 2011-03-03 14:02:18 +09:00
Bill Currie 181596f5bf Make relocation records store the space of the relocation.
The space is meaningless for op_* relocations as they are always in the
code space, but def_* relocations need to know which space holds the
location to be adjusted.
2011-02-12 22:34:38 +09:00
Bill Currie 67957a14df Bring back convert_name(), but siimplified.
It is now mainly for converting __FILE__ etc, handling expression symbols,
and checking for undefined identifiers.
2011-02-06 14:29:14 +09:00
Bill Currie a6e65488ec Remove the "test" parameter from test_expr.
The parameter became redundant at some stage.

Bill Currie 0624408317 Move the diagnostic functions into their own file. 2011-01-24 21:54:57 +09:00
Bill Currie 483cbeba03 Fix a few FIXMEs. 2011-01-24 21:13:37 +09:00
Bill Currie afc5b2827d Simplify def handling, use far data.
Since there is now a proper symbol table, defs are now just references to
memory locations and the symbol table takes care of duplicates.

Also, start using far data for ObjQC structures.

The qfo functions have been stubbed out until I figure out what to do with
object files in the new scheme.

Bill Currie 52b561f7cb Nuke bind expressions.
Since I'm planning on implementing CSE and other optimizations, they're
rather redundant (and I'm having trouble getting them to work).

Bill Currie 5deda9c9b9 Clean out ex_def as ex_symbol replaces it. 2011-01-19 22:25:04 +09:00
Bill Currie f2ef24d0cc Make symbols use the new value struct for constants. 2011-01-19 11:09:54 +09:00
Bill Currie e08efe036b Move the constant expression values into their own struct. 2011-01-19 08:43:24 +09:00
Bill Currie ea3895805b Rewrite much to use symbols and symtabs. Gut emit.c. Massive breakage.
That which isn't rewritten is horribly broken. However, this does include a
nice mechanism for building QC structs for emitting data.

emit.c has been gutted in the spirit of "throw one away".

There is much work to be done to get even variables emitted, let alone
code. Things should be a little more fun from here on.
2011-01-17 22:34:41 +09:00
Bill Currie 75ec6bf244 Clean out some unnecessary types from the progs engine and clean up the mess.
This is a nasty commit, sorry, but 99% of the commit is interdependent.

Bill Currie 67beaf4487 Nil is a constant, so allow it in global initializers. 2010-11-24 17:01:18 +09:00

Bill Currie 3fb03fc2be hah, should have been using __attribute__((used)) all that time (rather
than __attribute__((unused))). fixes the missing console in -x11
2005-08-04 15:27:09 +00:00
Bill Currie 8c10e2e355 this should fix the string case errors on sparc64 2004-05-15 01:00:47 +00:00
Bill Currie 51b0a66ac7 better constant folding with auto-conversion between scalar types (might
make that optional for non-constants)
2004-01-25 08:55:03 +00:00
Bill Currie f10829206a use a cast expression rather than and bind expression to do the unsigned
comparison for switches. clears the notice (bind seems to be correct in
general) and is more correct conceptually anyway.

Bill Currie a45223da6c d'oh, forgot about "default" 2003-02-28 05:18:49 +00:00
Bill Currie ef762e21eb allow initialized globals (since they're constant) to be used in most places
constants are required (switch, initializing globals, enums)
2003-02-28 04:54:07 +00:00
Bill Currie 761a7546dd re-arrange things so __attribute__ and __builtin_expect are properly
autoconfiscated so rcsid will continue to work with gcc 3.3

Bill Currie 46bad45c7a move s_file, pr_source_line and pr_error_count into pr, make the linker
errors more meaningful, and fix a blasted string.h issue (damn old gcc;P)

Bill Currie e17604f9c2 remove all arbitrary limits except for globals. they'll need a little more
work. Once they're done, it should take quite a big mod to crash qfcc due
to too many strings/statements/etc :)
