75aa28cfac Mark all subsequent blocks as reachable after if/goto merge. 
If an if/goto merge is done in the first dead block pass, no blocks after
the merge have their rechable flag set because they've never been tested.

8ddd58f951 Fix the dropping of the block after the merged if/goto. 
The naive implementation of the if/goto merging was letting the old target
of the if get dropped because the block would lose its label and thus be
judged unreachable because the preceeding goto block was still in the list.
Instead, when the if/goto are "merged", mark the goto block as unreachable,
the following block as reachable, and break out of the analysis loop to
force the removal of the goto block. Since the dead block removal function
loops until no action is taken, all other dead blocks will be removed.

e866619de6 Output basic block flow diagrams to files. 
The output can be controlled via --block-dot (not yet documented). The
files a named <sourcefile>.<function>.<stage>.dot. Currently, stage will be
one of "initial" (after expression to statement conversion), "thread"
(after jump threading), "dead" (after dead block removal), "final" (final
state before actual code emission).

The relative block number and the label user count are printed now.

6900907129 Remove dead labels when jump threading. 
This lets the dead block removal do a better job.
 2012-05-03 19:32:44 +09:00
Bill Currie
ab73a267cd Do not unconditionally remove labels from blocks. 
Labels can be shared between multiple flow-control instructions, so use the
label's used counter to determine when to remove the label. This was
causing problems with the jump threading.

78a9ba2557 Make expression alias chains not-a-bug. 
The common cause seems to be casting a cast (very common, and I'm not sure
just realiasing the expression would be right). It does't cause any harm
(particularly, it doesn't trigger alias def chains), so I won't worry about
it.
 2012-05-03 13:57:31 +09:00
Bill Currie
006882407d Fix the source of alias def chains. 
The actual bug might still be elsewhere, but at least now I know the alias
chains were coming from accessing .return and .param_N, which are unions
(not directly usable by the progs engine). Emitting a reference to a union
(or struct) would create an alias def, but an alias expression was created
in the expression tree to simplify return/param access. The double layer
(sometimes 3 or 4) alias isn't really neaded, so rather than layering the
aliases, just re-alias the alaised def.
 2012-05-03 13:28:16 +09:00

Bill Currie
5f676c367f Add a non-error diagnostic that can't be silenced. 
It is inteded for flagging buggy conditions in the compiler, particularly
after having fixed the original bug (in case something comes back from the
dead).

e267e0a664 Allow control of progdefs.h CRC writing. 
CRC writing defaults to off for non-v6 progs, but on for v6 progs. The
--progdefs option forces CRC writing.

ce278b2fbf Ensure .zero does not get a vector field for v6 progs. 
v6 progs expects .zero to be only 1 word. The code actually tried to keep
vector out of .zero, but it seems I'd rearranged the structure defintion
without updating the code that kills the vector field. Problem spotted by
divVerent.
 2012-05-02 22:29:17 +09:00
Bill Currie
4fe7efbed8 Add a test for end of function conditional return. 
divVerent was telling Spike about such a bug in fteqcc and I though I'd
better get in an explicit test for qfcc.

The order is high (unscaled) low (scaled by 1/256) rather than low

99c58cca73 Make exporting md16 files possible. 
Not sure if it actually works as the clients don't render the result
properly (can't see anything where the model should be), but the output
model does import back into blender properly.

 2012-04-19 22:16:30 +09:00
Bill Currie
6bae99d66c Create an animation script for imported models. 
The animation script is just a plist of relevant frame and skin
information. Documentation is included in the generated script.

ff05074e70 Set the fcurve interpolation to linear. 
Since qf does linear interpolation of verts, this seems to be reasonable.
Certaintly better than the rose-thorns I got because I haven't figured out
how to kick the auto-clamp.
 2012-04-19 18:49:53 +09:00

d500940983 Add support for writing plists. 
For now, only dictionariess, lists/tuples, bytes and strings are
supported.

Bill Currie
68bf0108fb Create a python version of qfplist. 
I've decided to use property lists to define mdl control scripts. Some
names will probably get changed, and I still need to write code for writing
a plist, but the hard part is pretty much done :)

196f2da585 Remove the fallback for missing image pack support. 
It's been in blender since 2.59 or so.

e25024c131 Build a single NLA track with strips for all actions. 
This removes the need for fakeuser :).

Anyway, with this, the model's animations can be viewed all in sequence
just by hitting alt-a.
 2012-04-16 15:42:49 +09:00
Bill Currie
4b29510bfd Set the name of the shape-key datablock to the model name. 
Note that this is the data block that holds the list of actual shape-keys,
rather than the shape-keys themselves. I'm not sure what it's correct name
is (it's just "Key" in RNA).

I really dislike this method of setting the name, but the use of "Key" as
the datablock name is actually hard-coded into blender's C code :/
 2012-04-16 13:33:45 +09:00
Bill Currie
0952e918dd Set fakeuser on actions. 
Without fakeuser set, blender will toss out the actions on save and reload.
Converting to an nla strip might take care of that, but I haven't figured
out how to do that yet, so avoid any nasty surprised for the user.
 2012-04-16 13:30:58 +09:00
Bill Currie
70f500a087 Use custom properties for model flags etc. 
Eye position, auto rotation, sync type and particle effects can now all be
edited in blender: both import and export do the right thing. The settings
can be found in the "QF MDL" panel of the "Object" tab of the properties
view.

eefa89e72e Remove the AM_CONDITIONALs from tools. 
Now that the tools directories aren't entered when those tools aren't being

9fbff2f4d5 Do an audit of the Makefile.am files. 
o All instances of LIBADD/LDADD have a corresponding DEPENDENCIES
    specificatiion.
  o libraries now use a lib_ldflags macro to keep things consistent
  o duplication of source/lib names has been minimized (particularly in
    the libraries; more work needs to be done for the executables)
  o automake spec blocks have been organized (again, more work needs to be
    done for the executables)

c8163fc0de Add an option to prevent the use of default paths. 
Despair has things locked down such that running qfcc during a build fails
due to lack of read access to /usr/local/lib. This is actually a good
thing as accidentally hitting old includes/libs (when a file gets deleted
in the tree) hides bugs. Thus, --no-default-paths to turn off default
search paths.

6ead583195 Ruamoko: Implement infinity. 
The special token __INFINITY__, like __FILE__ and friends, will expand to
a floating-point expression containing a value the C compiler considers
infinite. Obviously, this assumes that the system has relatively modern
float hardware -- but if it doesn't, having Ruamoko be able to represent
float infinity is the least of your problems. :)

91e65b6c80 Rename mplane_t to plane_t and clean up the mess. 
I got rather tired of there being multiple definitions of mostly compatible

now because I want to be careful when messing with the actual bsp format.

3b8ab404a0 Add the ability to save the extra model parameters. 
The params are eye position, flags and synctype. Provision is made for

1277c17cd9 Give the 24-8 bit converter a massive speedup. 
The biggest part of the speedup is reading from blender's image only once

cache the results for each color.

50795b8239 Calculate the model "size". 
The size is actually the average area in quake units of the mesh's
triangles. Again, my results are slightly smaller (0.025).

With this, all calculable fields are set. Only eye position, flags and
synctype remain.
 2011-09-24 13:18:23 +09:00
Bill Currie
07b5db64c6 Calculate the bounding radius. 
The calculated radius is a smidge (0.05) smaller than the original
(invisibl.mdl), but I think that's due to the difference in source data: id
used the original models, I'm using their output.
 2011-09-24 13:03:18 +09:00
Bill Currie
3b33d8dade Make the basis shape key active on import. 
Blender must have an active shape key before shape key animation will work.
This fixes the models being locked to the first frame until a shape key is
selected via the UI.

Bill Currie
bd840726c2 Fix the mangled faces. 
I /did/ see the warning about vertex index 0 in the obj importer script,
but I didn't take it seriously enough. This fixes both the twisted texture
on a couple of faces, and the truly mangled tris when exporting (using
invisibl.mdl for testing).

a80eef8bc4 Get the exporter mostly working. 
There seems to be some problems with the UVs, only one frame is exported,
and various model params don't get set (eye position, size, bounding

40f46f2ea3 Complete mdl writing. 
Except for the normal index in the frame bounds (and potentially frame
names with junk after the terminating nul), the output is identical to the
input for:

	mdl.write("test.mdl")
 2011-09-22 11:44:08 +09:00

some of the frame group code.
