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
Bill Currie 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
Bill Currie 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
Bill Currie 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
Bill Currie bc78b84869 Set the target of string relocs to the string index. 2011-03-04 21:29:10 +09:00
Bill Currie 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
Bill Currie 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
Bill Currie 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
Bill Currie 72fae608e5 Write the function start address to the progs file. 
Oops:P
 2011-03-04 18:46:28 +09:00
Bill Currie 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
Bill Currie 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
Bill Currie c5dac6d1d1 Transfer the type encoding. 
oops
 2011-03-04 14:29:22 +09:00
Bill Currie 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.
 2011-03-04 13:52:32 +09:00
Bill Currie e525727a24 Add a null type descriptor to the linker output. 2011-03-04 11:38:33 +09:00
Bill Currie 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
Bill Currie c99f3aba0e Add the new header files for make dist. 2011-03-04 00:11:13 +09:00
Bill Currie fd24524e13 More tests. 
I really need to sort out some test automation.
 2011-03-03 22:32:22 +09:00
Bill Currie 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.
 2011-03-03 19:07:37 +09:00
Bill Currie 4794d66f42 Change jumpb's opa type to integer. 
I'm not 100% certain this is correct...
 2011-03-03 19:06:17 +09:00
Bill Currie 4324486ae6 Give - unary expressions special treatment. 
The progs engine has no neg instruction, so need to implement -val as
nil - val
 2011-03-03 18:13:30 +09:00
Bill Currie f9e177efd6 Obtain the label to be removed from the correct place. 
This fixes the undetected dead block after "if return else return".
 2011-03-03 17:50:46 +09:00
Bill Currie ed901bd48f Drop unused labels rather than adding them to the statement block. 
However, even unused labels create a new statement block if necessary.
 2011-03-03 17:35:06 +09:00
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 90640614ef Compare symbols using the right method. 
That fixme was right :)
 2011-03-03 15:02:26 +09:00
Bill Currie 610d775bd1 Treat void values as the largest type. 
This fixes passing nil through a structure return value.
 2011-03-03 14:56:21 +09:00
Bill Currie bad5fddec4 Fix overloaded function resolution. 
Update the expression symbol pointer, not just the symbol name.
 2011-03-03 14:44:48 +09:00
Bill Currie fff4fc693e Fix value hashing and comparison in switch expressions. 2011-03-03 14:02:18 +09:00
Bill Currie 74e6b13aee Use alias expressions where possible when testing an expression. 2011-03-03 13:47:28 +09:00
Bill Currie d937172243 Create and use alias operands for alias expressions. 
This avoids the alias expression modifying the operand used in other
expressions.
 2011-03-03 13:46:07 +09:00
Bill Currie 022fde666f Implement unary expression statements. 2011-03-03 13:10:07 +09:00
Bill Currie 45de7327dc Implement alias expressions (finally). 
Alias expressions are like cast expressions, but never do any conversions.
 2011-03-03 11:06:10 +09:00
Bill Currie 59f520f4e7 Fix some parse errors that were lost in the noise. 2011-03-03 10:39:21 +09:00
Bill Currie 848994323e Support enums in expressions that support scalar types. 2011-03-03 10:36:43 +09:00
Bill Currie c12211d8bb Support enum results for boolean expressions. 
eg enum BOOL x = a && b;
 2011-03-02 22:46:55 +09:00
Bill Currie c06dd776d2 Fix expression initializers for arrays and structs. 2011-03-02 22:28:17 +09:00
