4828934e50 Fix a equality check typo. 
Fixes bad code generation when assigning to vector.x in a function with no
parameters and the vector is the first local var.

f58c2fef5a Switch QF's quaterions from wxyz to xyzw. 
After messing with SIMD stuff for a little, I think I now understand why
the industry went with xyzw instead of the mathematical wxyz. Anyway, this
will make for less pain in the future (assuming I got everything).

b7aa5bb8fe Fix an oops messing up edict size. 2018-10-12 14:33:26 +09:00
Bill Currie
f8606ebab8 Fix a object file segfault when spaces have no data. 
ie, don't attempt to copy memory from a null pointer (just copy the null
pointer).

3bd9f96b07 Make internal error messages a little more helpful. 
They now include the file and line of the compiler as well.

a096babb1f Duplicate memory when creating a qfo from progs. 
Fixes some double-free bugs when linking after compiling.

82809eb856 Simplify the call to PR_LoadProgsFile. 
I've decided that setting pr.max_edicts and pr.zone_size as part of the
local progs initialization rather than in PR_LoadProgsFile makes more
sense. For one, it is unlikely for the limits to change every time progs is
reloaded. Also, they seem to be a property of the VM rather than the progs.
However, there is nothing stopping the caller from updating max_edicts and
zone_size every call.

673b45be05 Add diagnostic hooks. 2018-10-09 12:46:13 +09:00
Bill Currie
34bcf7faab Do a pure/const/noreturn/format attribute pass. 
I always wanted these, but as gcc now provides warnings for functions that
could do with such attributes, finding all the functions is much easier.
 2018-10-09 12:42:21 +09:00
Bill Currie
71569b45c9 Pre-format diagnostic messages. 
This will make it easier to hook diagnostics enabling unit tests.

113e0d82ba Fix a signed comparison error. 
Not sure how this fix got lost.
 2018-09-09 16:48:19 +09:00

59e85b7d5e Fix a pile of dead assignments. 
Some were actual bugs!

59b04dbcca Make many qfo int fields unsigned. 
I don't remember why I thought signed was a good idea, but unsigned does
make more sense for most fields.

8fd5be0ee0 Fix a pile of sizeof goofs. 
While scan-build wasn't what I was looking for, it has proven useful
anyway: many of the sizeof errors were just noise, but a few were actual
bugs (allocating too much or too little memory).
 2018-09-07 20:00:57 +09:00

2fcda44ab0 Kill dag leaf nodes on assignment. 
Fixes the failing swap test caused by a's original value being used (via t)
after being written.

cb366dd825 Better flow dot dump "scripting". 
Not sure I want to keep the statements in the live dump, but the system
is more flexible now.
 2018-08-23 20:07:11 +09:00

cdbdf3f0eb Make print_operand global. 2018-08-23 20:05:16 +09:00

0f279cd3f0 Add a comment about fake statement numbers. 
I had forgotten how they worked (not surprising after 6 years).

1b84ea747c Dump statements during flow analysis. 2018-08-21 15:56:39 +09:00

5ba13d759b Fix a FIXME. 
Set of everything got added shortly after that FIXME was added, but I
forgot to fix it.

fbdf560a7a Rename print_extra_live to print_flow_vars. 2018-08-21 15:55:11 +09:00

5dbb7b6d4d Handle all modelgen commands. 
Just in case someone ever adds models.qc to progs.src.
 2018-08-20 00:11:02 +09:00

027e76b4c9 Add a doc block to parse_cpp_line. 
It took me too long to figure it out :P
 2018-08-20 00:09:20 +09:00

b795beb520 Add support for \? to qc strings. 
And fix up the man page a bit.

932647bad3 Fix a segfault with switch on an undefined symbol. 
Forgot to check if the test expression was not an error.

bf40f0126e Convert vector expressions when passing parameters. 
Calling a function with [vector stuff] caused an ICE.

1061256c4f Add a missing expression type to dot_expr. 2016-01-08 21:15:47 +09:00
Bill Currie
431074d58f Update label destination when moving labels. 
This fixes a segfault when optimizing the empty-body test. The label was
getting moved, but the statement block to which it pointed was not updated
and thus it pointed to dead data.

d54ee6c8c3 Do not promote debug messages to warnings. 
I think I copied the notice code for debug and forgot to edit the
promotion. Oops.

2cd59c962c Rename qfcc's basename to file_basename. 
Avoids naming conflicts with JohnnyonFlame's toolchain.

f5501fbf24 Fix a pile of automake deprecation warnings. 
s/INCLUDES/AM_CPPFLAGS/g

I <3 sed :)

c88d1987a1 Add warnings for empty blocks in if/else/do. 
Saw a discussion of such in #qc and that gcc implemented it. I realized it
would be pretty easy to detect and very useful (I've made such mistakes at
times).

db460155e9 Fix multiple function calls in expressions. 2013-09-27 23:15:57 +09:00
Bill Currie
4bc40b3917 Rewrite binary_expr(). 
It is now in its own file and uses table lookups to check for valid type
and operator combinations, and also the resulting type of the expression.

This probably breaks multiple function calls in the one expression.
 2013-09-27 23:15:57 +09:00
Bill Currie
ec98954dfc Remove the small struct optimization. 
It might cause trouble for the binary_expr() cleanup.
 2013-09-27 23:15:57 +09:00
Bill Currie
3295370328 Expose and use field_expr(). 
This may cause problems later on, but it is needed for the binary_expr()
cleanup.
 2013-09-27 23:15:57 +09:00
Bill Currie
ca9693d9cd Expose convert_from_bool(). 2013-09-27 23:15:57 +09:00
Bill Currie
b66cbeeb57 Run fold_constants on comparison operands. 
This is a bit of a workaround to ensure the operands have their types
setup correctly. Really, binary_expr needs to handle expression types
properly.

This fixes the bogus error for comparing the result of pointer subtraction
with an integer.
