21b5ea8075 Remove unreachable nodes. 
Any nodes still marked as unreachable (dfn < 0) need to be removed so
graph->dfo is valid (only one node 0).

3270bb3f5e Make node numbering int rather than unsigned. 
(unsigned) -1 is not what I wanted :P

927335a29c Break out the successors and edges code. 
This will make for nicer code when everything is looped for unreachable
node removal.

c7ae58d7a3 Allow flownodes and sblocks to be numbered independently. 
The numbering will need to be independent when unreachable nodes are
removed.

9d35ca607f Mark all nodes as unreachable. 
flow_build_dfst() marks a reacable node as such by setting the node's dfn
to a value >= 0.

32556b7210 Initialize the graph's depth first order array. 
Unreachable nodes will cause the first elements of the array to remain
unwritten by df_search. This fixes the segfaults caused by unreachable
nodes (the reason they were an internal error before).

a7e9defebd Remove the non-initial parentless node check. 
Its purpose was to catch when the old dead block remover failed to remove
unreachable blocks, but that code is now gone.
 2012-12-19 15:31:32 +09:00
Bill Currie
83ead0842f Remove the dead block removal code. 
It has proven to be too naive as it is unable to remove unreachable loops.

b9c5769e6d Allow messages to nil. 
That is, [nil message];. I just found out this is "perfectly legal"
(http://www.otierney.net/objective-c.html).

f1b1822528 Add the sound builtins to qwaq. 
All one of them :P
 2012-12-17 15:41:56 +09:00
Bill Currie
bf141a7d66 Enable sound in qwaq-x11 :) 
If qwaq-sdl ever gets done (anybody know where some round twits are?), it
too will have sound. :)

7b38b0b339 Make S_Init safe to use with a null viewentity. 
Current work in qwaq doesn't need 3d spacialization, so it wants to pass
null for the viewentity pointer.

463e41082a Support struct style initializers for vectors and quaternions. 
The current implementation probably needs more work, but for the case where
I needed it, it does the job.
grid.r💯     vector      size = {range, range, 0};
0115 store.f range, size
0116 store.f range, [$2ac]
0117 store.f .zero, [$2ad]

e17d8ac9db Add ruamoko wrappers for the set api. 
This includes both normal functions and a Set class (and SetIterator
class). Most of the methods are implemented as builtins.

3a9fe196b6 Get the return param right for messages to nil. 
R_INT(pr) = R_(INT)(pr); is not exactly what I had intended :P

7ed490c434 Allow nil when replacing objects in an array. 
I want this in a little project, but I also want to consult with Deek about
it, so I've only commented out the code.

f631f514e9 Fix the obj_error family of functions. 
It seems they were written before quaternion support was added and were not
updated to take into account the variable size of parameters. Now at least
Object's -error: works.
 2012-12-16 13:19:31 +09:00
Bill Currie
11b991cf9d Print the error message before the state dump. 
Normally, the order doesn't matter, but when tracing code, it becomes very
difficult to tell where the trace ends and the dump begins. Printing the
message first puts the message between the trace and the dump: much easier
:)

d6ec944e5f Set a builtin methods func pointer. 
Forgetting to set the func pointer is what caused the bogus "does not
respond to" message for -error:.

aa14271764 Make param/format specifier mapping easier to read. 
Just a bit of white space.

2317811f2b Don't allocate space for locals for builtin functions. 
While the symtab is needed for debug info, there is no need for any actual
data to be allocated for a builtin function's locals.

f3e2e239b8 Use the class name in type encodings. 
After all that effort getting the class def initialized early enough for
type encodings to work, it proved to be a problem: just including a header
with an interface in it would cause linker errors if there was no
implementation available (even if the class is never used).

101ca22b5a Fix a couple of warnings found by the mxe gcc. 
Finally, a recent gcc for our mingw builds :)
 2012-12-14 17:07:53 +09:00

fb00391749 Update the mingw cross scripts for MXE. 
I got MXE to build (took only an envvar and a couple packages, yay doc
reading), so I thought it time to update the scripts to use it (they assume
/opt/mxe).

461572e6ad Fix constant folding for vectors and quaternions with floats. 2012-12-14 12:48:09 +09:00
Bill Currie
732d6a1520 Provide emulation for vector / float and quaternion / float. 
The VM doesn't have such instructions, so emulate them via
vector * (1 / float) and quaternion * (1 / float).

dc55034708 Mark aliases as live when a label is attached to a leaf node. 
This fixes the lost return values in the menus.
 2012-12-13 21:20:21 +09:00
Bill Currie
a7b7a114bc Don't kill the node to which an alias is being assigned. 
This does not fix the lost return value the menus as that is caused by the
alias not being marked live when it should be.

3e38c4aa48 Merge branch 'qfcc-cse' 
qfcc now does local common subexpression elimination. It seems to work, but
is optional (default off): use -O to enable. Also, uninitialized variable
detection is finally back :)

The progs engine now has very basic valgrind-like functionality for
checking pointer accesses. Enable with pr_boundscheck 2

47c721b32e Clear the dstring in test-harness's printf builtin. 
PR_Sprintf always appends to the result dstring. I'm not sure if this is by
design or a bug, so I'll leave it be for now.

decc3845c5 Kill any aliases when assigning to an aliased def. 
Temps aren't supported yet :P

The alias defs themselves aren't killed (still want any assignments to
occur) but rather, their nodes are. Also, edges to the alias defs' nodes
are added to the assigning node. Fixes structlive.r :)
 2012-12-13 14:43:43 +09:00
Bill Currie
2dc60d4f9a Allow tests for full overlap of defs. 
Not actually used yet, but I imagine I'll want it.

821081c9c8 Use the desination type for moves in assign_expr. 
for <struct> = nil; the source type is void and thus probably the wrong
size.

503154257c Fix an uninitialized variable. 
Yay valgrind, boo taniwha.

3665a0566a Add a test for struct writes. 
This tests local kills via aliases.

0ff6e8a471 Correct some spaces in the type dump output. 2012-12-13 13:33:13 +09:00

cf05f65596 Add int_val and uint_val to @param and @zero. 
I got fed up with using "int" types, but the members being "integer"
(hold-over from before the int rename).
Also, correct the names of those types and @va_list (error reporting was
chopping off part of the name).

5681e0fd42 Treat certain move instructions as assignments. 
MOVE (static move) and MOVEP to a pointer constant know exactly where their
data is going, so treat them similarly to assignments: save their
distination operands (the addressed def for MOVEP) and mark them as
defined.
 2012-12-13 12:50:00 +09:00

c61e03a0b9 Clean up operand creation. 
Rather than having the creation scattered through the code, use helper
functions. Makes exposing operand creating saner.

d990a956c0 More label count paranoia. 
MOVEP can generate 4 daglabels.
 2012-12-13 12:48:07 +09:00

c295a0473e Add edges from call nodes to their param nodes. 
Assinments to .param_N (0-7 for call, 2-7 for rcall) must occur before the
call, or weird things will happen.
 2012-12-13 09:55:28 +09:00
Bill Currie
c477191488 Be a little more paranoid about daglabel counts. 
I'm still a little worried about the number of labels needed with heavy
alias usage.

204a0b3f72 Make def_visit_all return the actual result of visit. 
This way, def_visit_all is a little more useful (though I think I might
redo the one case that's using this feature).

028b19888f Check aliases for liveness when removing dead vars. 
The live var flow analysis doesn't check for aliases. Rather than changing
it to check for aliases (which might break uninitialized var analysis, as
it uses "use" from the live var analysis), make dag_remove_dead_vars do the
check. Fixes the misplaced text in the menus.

2ce65d931e Use exact texture coords for 2d pics in glsl. 
Moving the texture coordinates in 1/4 pixel made a mess of the 2d pics
(very noticable on the round crosshair).

Also, fix the offset for pic based crosshairs in glsl, and use just one
