85bffbcad0 Add is_integral() to check for integral types (integer, short, enum). 2011-03-06 11:25:12 +09:00
Bill Currie
17a9dff769 Avoid freeing an operand twice. 
Due to the way operands are used, they can be freed twice in dead-statement
removal. Detect the double-free and ignore it.

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.

8cfa80b5d4 Implement think expressions. 2011-03-05 18:01:37 +09:00

7209c61912 Fix initializing local float variables with an integer constant. 
Run the assignment expression through fold_constants to handle any
necessary conversions and error checking.

a3c1f339fc Gracefully handle undefined symbols in entity field expressions. 2011-03-05 17:22:04 +09:00

fbea276ede Yet more tests. 2011-03-05 17:21:19 +09:00

7314b944d5 Bring back the offset alias support. 
Accidently nuked it when fixing .return etc.

e7e8220246 Dump code addresses as hex, too. 2011-03-05 16:25:56 +09:00
Bill Currie
2f74e6e4bf Nuke the old progs global. 
It is no longer needed thanks to the new qfo conversion functions.
 2011-03-05 16:24:53 +09:00
Bill Currie
fcb567fc98 Use the correct function number when updating the function def. 
Functions are 1 based in progs bug 0 based in qfo files.
 2011-03-05 16:00:39 +09:00
Bill Currie
535dfad305 Emit defs for far data. 
They will break when the offsets exceed 64k, but they are needed for
debugging.
 2011-03-05 15:59:14 +09:00
Bill Currie
97b1ceceb0 Fix line number info. 
line number info is now 1 based rather than 0 based (to better detect when
a function does not have line number info).
 2011-03-05 15:40:08 +09:00
Bill Currie
1dea86a3e4 Update debug info loading when dumping qfo files. 2011-03-05 14:53:41 +09:00

cfefd79e07 Fix the source of bogus string relocs. 
Nested aggregate initializers were corrupting themselves.
 2011-03-05 09:21:12 +09:00

7c95913c61 Avoid segfaulting with bad string relocs. 2011-03-05 09:07:16 +09:00
Bill Currie
8eb5fd653a Perform the relocations!!! 
line numbers seem to be broken, but the code itself looks good.
 2011-03-05 08:41:14 +09:00

fe7be543f8 Correctly update the offset of code relocs. 2011-03-05 08:39:47 +09:00
Bill Currie
7fd839a5ed Handle chains of alias defs so relocs will be emitted. 2011-03-05 08:39:16 +09:00
Bill Currie
bbedbf5c9c Add the .return etc symbols to the symbol table. 
This puts their defs into the object file.
 2011-03-05 08:37:51 +09:00

c3f1c186f8 Resolve types of .return etc. 2011-03-05 08:36:55 +09:00

Bill Currie
6d02555ca9 Reorganize the offset calculations. 
keep the offset calculations separate from the data transfers for better
clarity in what is happening.
 2011-03-04 23:31:09 +09:00

e62163e569 Nuke any invalidated relocs. 2011-03-04 21:46:19 +09:00
Bill Currie
2565e0db32 Update reloc targets when linking. 2011-03-04 21:29:47 +09:00

7fb22bd1e4 Make D_STRING() more useful and add D_GETSTR() 2011-03-04 21:28:12 +09:00
Bill Currie
e04f6266b1 Nuke def_list from defref_t. 
It didn't work :/.
 2011-03-04 20:40:01 +09:00

5a552d8841 Add the null function. 2011-03-04 20:29:40 +09:00
Bill Currie
368a3826be Redo the offset and size calculations for qfo_to_progs(). 2011-03-04 20:14:02 +09:00

cd12a78f93 Replace some accidentally deleted code. 
Forgot to commit it the first time round, then rebase messed me up and I
didn't notice until after pushing. *sigh*
 2011-03-04 19:02:47 +09:00

72fae608e5 Write the function start address to the progs file. 
Oops:P
 2011-03-04 18:46:28 +09:00

2211a807d4 Do not relocate builtin functions. 2011-03-04 18:46:25 +09:00
Bill Currie
d6d8b5b49d Generate the debug symbol file. 2011-03-04 18:46:05 +09:00

9a96febdf5 Fix the hordes of bogus defs. 
They were caused by unused external defs, so not processing unused externs
in the first place is the simplest solution.
 2011-03-04 14:51:09 +09:00
Bill Currie
7b7f4c70e0 Correct non-external def processing. 2011-03-04 14:33:03 +09:00

c5dac6d1d1 Transfer the type encoding. 
oops

d0b4546383 qfprogs isn't yet fully functional... 2011-03-04 13:54:29 +09:00
Bill Currie
2992d66f87 Simplify the tag used for anonymous structs etc. 
Hopefully two files with the same file name won't have anonymous stucts on
the same line.

e525727a24 Add a null type descriptor to the linker output. 2011-03-04 11:38:33 +09:00

3a828ca5c2 Ensure work spaces are always connected to their data. 2011-03-04 11:18:56 +09:00
Bill Currie
45c3dd67a8 Some test updates. 2011-03-04 08:27:26 +09:00
Bill Currie
4192ef835c Delay initialization of obj_module_t as long as possible. 
This keeps the type descriptor out of progs that never use any
Objective-QC features.
 2011-03-04 08:25:50 +09:00

c99f3aba0e Add the new header files for make dist. 2011-03-04 00:11:13 +09:00

fd24524e13 More tests. 
I really need to sort out some test automation.

ee9045c377 Emit code for jump tables. 
With this, the entirety of the ruamoko tree builds (though the progs will
be broken in various ways: mostly unrelocated references).
 2011-03-03 19:09:00 +09:00
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.

4324486ae6 Give - unary expressions special treatment. 
The progs engine has no neg instruction, so need to implement -val as
nil - val

f9e177efd6 Obtain the label to be removed from the correct place. 
This fixes the undetected dead block after "if return else return".
