Bill Currie 564b7b9968 Use abstract_decl instead of type wherever a generic type is needed. 2011-02-03 10:53:59 +09:00
Bill Currie a208aed6ef Fix a segfault when encoding incomplete structs. 2011-02-03 10:52:42 +09:00
Bill Currie 22ccd41164 Give struct types a name.
Use the struct/union's name (minus "tag ") for the type name.

Bill Currie d12cdca758 Functions and enums now seem to be working properly.
find_type now operates recursively (depth-first) so built up typechains
work as expected.

@overload is treated as a specifier (directly as a storage class, similaar
to typedef).

Bill Currie 52799a4e1c Must merge specifiers :P 2011-02-02 22:59:08 +09:00
Bill Currie 4420a7125e Ensure structs get added to the symbol table. 2011-02-02 22:53:53 +09:00
Bill Currie a4eaa2a89b Allow typedefed types and classes in parameters. 2011-02-02 21:58:53 +09:00
Bill Currie aeecdc84dc Get typedef working. 2011-02-02 21:58:11 +09:00
Bill Currie cca829aa6b Remove a stray semicolon from the grammar. 2011-02-02 21:57:41 +09:00
Bill Currie 400abe7fce Allow freeing of typechains. 2011-02-02 15:15:24 +09:00
Bill Currie 1fe031e8cb Build C style var/func/abs decl types from the outside in.
QuakeC style are built from the inside out.

Bill Currie 7fb8c8247e Don't do a find_type on the parsed function.
This is needed for C style declarations, but breaks QuakeC style. The fix
is to do the find_type once the return type has been filled in.
2011-02-02 15:08:59 +09:00
Bill Currie 1452da676d Allow types to be built from the outside in.
This is required for C style decl processing.

Bill Currie ac91e9376b The big type-system rewrite. Horribly broken :)
While broken, it is good enough to compile modulo.r.

This gives qfcc C's type system with QC specifics bolted on top (rather
than trying to cram C's type system into QC's). Pointers and arrays now
use C syntax and semantics (though I think there's a lot of breakage in
there at the moment). Functions themselves are still dual mode: both QC
style and C style are available.

Bill Currie d11d128c96 Avoid segfaulting on errors. 2011-02-01 21:18:39 +09:00
Bill Currie 80ce179bc2 Scan the param list for problems with void. 2011-02-01 21:18:08 +09:00
Bill Currie c53001800a Create a struct for representing specifiers.
The specifiers are yet to come (next few commits), but this will be
necessary when they do.
2011-02-01 21:15:51 +09:00
Bill Currie 917c5f08b0 Make a var representing the default type.
The default type for vars is integer for ruamoko and float for v6 qc.
2011-02-01 21:12:02 +09:00
Bill Currie 54c14eb899 Add "return" to pascal.
I'm still not sure I'll keep it, but it's useful for testing.
2011-01-30 22:16:59 +09:00
Bill Currie e7424e1496 Don't segfault on bare return statements.
I will probably need to do something about the required operand for v6
progs, but this will do for now.
2011-01-30 21:43:56 +09:00
Bill Currie 440a13b649 Untwist params' knickers for pascal, too. 2011-01-30 21:42:10 +09:00
Bill Currie 861ab93274 Don't type-check against the wrong type :P 2011-01-29 09:56:08 +09:00
Bill Currie afc6605739 Don't set the space for external defs. 2011-01-29 09:55:14 +09:00
Bill Currie d80a3413e5 Fix a segfault when freeing locations.
When chasing linked lists with a double pointer, must check the first
dereference and not the pointer itself.

Bill Currie e1226bd3f1 Quaternions aren't vectors :P 2011-01-28 21:57:04 +09:00
Bill Currie 2cce903cc9 Set the default storage class for local vars. 2011-01-28 21:56:17 +09:00
Bill Currie bc7d42d176 Immediate constants now work, though still not shared. 2011-01-28 21:39:01 +09:00
Bill Currie 3c95667b79 Print data contents for most simple types. 2011-01-28 21:21:29 +09:00
Bill Currie 4476074021 Print more addresses as hex. 2011-01-28 18:03:26 +09:00
Bill Currie 4837e0bd18 Fix most of the FIXMEs in qfcc.c.
Functions and defs seem to be relocated correctly. Constants are very
broken, however.
2011-01-28 15:17:30 +09:00
Bill Currie 834417b8c8 Add "debug" diagnotic printing, and use it.
Debug diagnostics are silent for verbosity levels less than 1.
2011-01-28 13:28:45 +09:00
Bill Currie a37bdd9fb5 Free removed sblocks. 2011-01-28 13:23:20 +09:00
Bill Currie 80424f6ad5 Ensure functions are always properly terminated.
Control that reaches the end of a function must see a return statement.
2011-01-28 13:14:30 +09:00
Bill Currie 9159daf99d Do simple unreachable block analysis and dead block removal. 2011-01-28 11:45:04 +09:00
Bill Currie 90a2738459 Add the label to the block to which it refers. 2011-01-28 11:41:53 +09:00
Bill Currie c158b14286 Remove the labels list from the pr struct.
I'm not sure they were ever needed.
2011-01-28 11:40:25 +09:00
Bill Currie 4738c767a2 Fix branch label handling.
Conditional branches and goto now go to the correct location.
2011-01-27 21:11:32 +09:00
Bill Currie 95b17d9fd4 Rename add_statement_ref to add_statement_def_ref. 2011-01-27 21:10:37 +09:00
Bill Currie f72d6d6a27 Fix a typo in the opname for integer modulo. 2011-01-27 21:03:11 +09:00
Bill Currie bd78b8a7ee Enable more end-of-compilation code. 2011-01-27 15:44:12 +09:00
Bill Currie cdea1d07aa Produce code for progs.src mode.
Separate compilation will take fixing object files.

The generated code is broken due to various relocation fixups being
broken, and float immediates seem to be badly broken.

Debug information is broken too.
2011-01-27 15:44:11 +09:00
Bill Currie c7bbd40df6 Give special treatment to opcodes that have void operand types. 2011-01-27 15:44:11 +09:00
Bill Currie 71b5decbe8 Get assignments to .return working.
I really do not like the mechanism I currently use for handling pointer
derefences vs pointer assignments, but this will have to do for now until
I can get qfcc producing code again.
2011-01-27 15:44:11 +09:00
Bill Currie 56106892c8 The & operator produces a pointer, not void. 2011-01-27 15:44:10 +09:00
Bill Currie 1c3cc571f1 Pascal variables need defs too. 2011-01-27 15:44:10 +09:00
Bill Currie f532fbc6df Convert all integer operands to float for v6 progs.
Converting only opc is no longer enough.
2011-01-27 15:43:59 +09:00
Bill Currie 1ed1efbdfb Implement the ROTL macro correctly.
Bit rotation requires unsigned ints.
2011-01-27 15:43:50 +09:00
Bill Currie a6e65488ec Remove the "test" parameter from test_expr.
The parameter became redundant at some stage.
2011-01-27 08:31:51 +09:00
Bill Currie f7d60397fb Set the type for zer_def used by labels. 2011-01-26 22:43:59 +09:00
