1246fd9e30 Use the correct size when growing a data space. 2011-03-07 13:36:00 +09:00
Bill Currie
02a70ebe1c Remove the auxfunction manipulation from the compiler proper.
It was broken code in the first place (realloc and pointers), and is
redundant with the new linking process.

16103f9018 Fix param mangling for qc style functions. 2011-03-07 10:43:38 +09:00
Bill Currie
29cac0fe3a Optionally create *_[xyz] symbols for accessing vector components.
"vector-components" in code options controls this feature. The default is
off for advanced code and on for traditional code. Disabling
vector-components prevents the comonent names polluting the namespace and
reduces the number of globals needed for vector fields if the components
of that field are never used.

66447df6b3 Undo the offset relocation of local defs.
The debug info expects local defs to be 0 based, so once relocations in
the progs data have been completed, undo the local def offset relocation
so that the correct offsets will be written to the debug info.
2011-03-06 21:05:25 +09:00
Bill Currie
b2f0c9a127 Dump the local defs for functions when debug info is available. 2011-03-06 21:03:12 +09:00

Bill Currie
993d05b3d3 Support taking the address of alias expressions.
Taking the address of an alias expression undoes the alias but uses the
aliased type.

8712d30d1a Make entity field defs static.
Entity field defs need to be static in order to avoid clashing with their
field variables.

The previous method made too many assumptions.

fe4df03896 Add is_float ().
For now, it checks just floats, but I might one day add doubles.
2011-03-06 11:35:15 +09:00
Bill Currie
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.
2011-03-06 11:19:09 +09:00

28f4de94d2 Fix switch statements so the work in the new scheme.

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).

cd12a78f93 Replace some accidentally deleted code.
Forgot to commit it the first time round, then rebase messed me up and I

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

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.

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".
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.

d937172243 Create and use alias operands for alias expressions.
This avoids the alias expression modifying the operand used in other
expressions.

022fde666f Implement unary expression statements. 2011-03-03 13:10:07 +09:00

4a99f8dcbd Write the linker output to progs.dat.
There is much breakage, but qfcc now produces a progs.dat from either
progs.src or object files. Better yet, the progs.src result is passed
through the linker, removing much duplicate code.
2011-03-02 20:51:00 +09:00
Bill Currie
29985efcef Expose some linker functions to the rest of the compiler.
They proved to be useful for cleaning up the final compilation stages.
2011-03-02 20:48:55 +09:00
Bill Currie
8cdd28f534 Use qfo_to_progs() for dumping qfo data.
Yay, less duplicate code, and better yet, qfo_to_progs gets some much
needed testing :).
2011-03-02 19:08:11 +09:00
Bill Currie
ecb995a8f7 Rewrite qfo_to_progs() to go direct from qfo to progs.dat.
