7e293a38e8
Check for double-chaining of types.
...
Chaining a type twice will form a loop in the type list, causing find_type
to go into an infinite loop.
2012-11-08 17:14:33 +09:00
a3a22f2a1b
Add the ability to dump qfo type encoding.
2012-11-08 17:06:38 +09:00
ed4018fd8d
Clear out the function overloading tables between compiles.
...
Fixes some issues with multiple compiles (especially mixed languages!).
2012-11-01 20:53:33 +09:00
f8bdd909cc
Separate out C and html quoting into separate functions.
...
Dot sometimes wants normal C quotes, othertimes html. Quite annoying,
really, but this is cleaner anyway.
2012-10-30 12:31:22 +09:00
034139b806
Move some code around so it's more accessible.
2012-10-27 11:43:29 +09:00
144387c3e3
Add shared.h to the dist files.
2012-10-26 16:16:46 +09:00
f14d8060e0
Merge qfpc into qfcc.
...
Since gnu bison and flex are required anyway, no harm in using their api
prefix options. Now, qfcc can compile both QC/Ruamoko and Pascal files
(Pascal is (currently?) NOT supported in progs.src mode), selecting the
language based on the extension: .r, .qc and .c select QC/Ruamoko, .pas and
.p select Pascal, while anything else is treated as an object file (as
before).
2012-10-26 16:01:41 +09:00
1364bff91b
Add an extended mode to qfcc.
...
Extended mode allows extra keywords (switch, for, etc) that are compatible
with v6 progs.
2012-07-14 17:16:33 +09:00
23a38738fc
Massive whitespace cleanup.
...
Lots of trailing whitespace and otherwise blank lines.
2012-05-22 08:23:22 +09:00
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).
2012-05-04 09:45:51 +09:00
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).
2012-05-03 13:24:24 +09:00
cb8fe4eb38
Correct a "spelling" error.
2012-05-03 11:54:36 +09:00
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.
2012-05-03 00:22:24 +09:00
bc1b483525
Nuke the rcsid stuff.
...
It's pretty useless in git.
2012-04-22 10:56:32 +09:00
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.
2012-01-04 13:53:04 +09:00
d910c14935
Clean up some doxygen warnings.
2011-07-10 19:12:07 +09:00
55cc0f9206
Bring back the unsigned type (PROGS version bump)
...
This is only low-level support (the unsigned keyword still does not work),
but sufficient to make switch statements using jump tables work.
2011-04-09 10:07:47 +09:00
c4a398850a
Fix defs as constants for vectors and quaternions.
2011-04-04 21:31:59 +09:00
8d3508cf20
Allocate space for temp defs using size rather than type.
...
Statement operands throw away the high level type information, so store
type size in the operand and use this size for allocating space for temps
rather than using the low-level type.
2011-03-23 21:32:14 +09:00
9b62c8c126
Rename ty_type_e to ty_meta_e and type_t.ty to type_t.meta
2011-03-22 16:06:47 +09:00
f1d9570dc8
Fix constant value type handling.
...
Rename immediate.[ch] to value.[ch] and clean up the mess.
Add convert_value() to convert the type of a value (only scalar types).
2011-03-22 12:24:39 +09:00

Close a potential buffer overflow.
2011-03-09 11:09:46 +09:00

Explicitly select between direct and indirect moves.
2011-03-09 10:30:57 +09:00
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.
2011-03-07 13:33:02 +09:00
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.
2011-03-07 10:21:40 +09:00
fe3d228658
Maintain a symbol table for entity fields.
2011-03-06 15:38:19 +09:00
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
85bffbcad0
Add is_integral() to check for integral types (integer, short, enum).
2011-03-06 11:25:12 +09:00

Implement think expressions.
2011-03-05 18:01:37 +09:00

Perform the relocations!!!
...
line numbers seem to be broken, but the code itself looks good.
2011-03-05 08:41:14 +09:00
7fb22bd1e4
Make D_STRING() more useful and add D_GETSTR()
2011-03-04 21:28:12 +09:00

Generate the debug symbol file.
2011-03-04 18:46:05 +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.
2011-03-04 08:25:50 +09:00
c99f3aba0e
Add the new header files for make dist.
2011-03-04 00:11:13 +09:00
c5ecc170b6
Give labels a usage count to detect unused labels.
2011-03-03 15:28:49 +09:00
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
45de7327dc
Implement alias expressions (finally).
...
Alias expressions are like cast expressions, but never do any conversions.
2011-03-03 11:06:10 +09:00
c12211d8bb
Support enum results for boolean expressions.
...
eg enum BOOL x = a && b;
2011-03-02 22:46:55 +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
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
ecb995a8f7
Rewrite qfo_to_progs() to go direct from qfo to progs.dat.

Encode the basic type for functions, fields and pointers.
...
Very important for distinguishing them from other types.

Update the qfo access macros for the new format.
2011-02-25 09:38:22 +09:00

Add a field for loose relocation records.
...
Loose relocation records are those that are not bound to a def or a
function.
2011-02-24 15:21:06 +09:00

4c11304c8d
Documentation tweaks.
2011-02-21 08:41:03 +09:00
bffc1dd239
Clean up objective-qc type encoding.
...
Structures etc now never encode the fields as well (I might revert that
at some time). Type parsing has been removed: it has proven unnecessary
and overly complicated, and the new qfo encoding should be more useful.
2011-02-18 20:51:04 +09:00
7251bc91fa
Enhanced type encoding.
...
This creates a compact representation of types as seen by qfcc. This is
intended mainly for debuggers.
2011-02-18 09:06:05 +09:00
bceb98e5a4
Create structures for new qfo format.
...
This breaks a lot of existing code, so that code has been commented out
for now.
2011-02-17 15:02:09 +09:00
9c9a71f1af
Allow defs to specify use of offset relocations.
...
Access to struct fields in near data can be done using only one operand,
but offset relocs need to be used. However, as not all defs want offset
relocs, a flag has been added to the def struct.
2011-02-15 22:55:15 +09:00
4336fc2c73
Move method function defs into the far data space.
...
As they are never referenced directly by instructions, there's no need for
them to be in the near data space, taking precious def locations.
2011-02-15 15:33:18 +09:00
19f6faf0ad
Fix aggregate initializers.
...
Initializing arrays and structs seems to be working.
2011-02-15 09:30:37 +09:00
d162838299
Resurrect constant_expr().
2011-02-15 09:28:27 +09:00
0b5565396b
Add a class type to symbols and rework the CLASS_NAME handling.
...
This fixes the problem with [Array alloc] producing a warning about Class
not repsonding to -alloc.
2011-02-13 16:05:09 +09:00
c4f364fd37
Emit pointers properly.
...
Rename ReuseConstant to emit_value and use emit_value to emit any non-short
constant. This fixes the null pointer in the call to __obj_exec_class.
2011-02-13 10:09:42 +09:00
181596f5bf
Make relocation records store the space of the relocation.
...
The space is meaningless for op_* relocations as they are always in the
code space, but def_* relocations need to know which space holds the
location to be adjusted.
2011-02-12 22:34:38 +09:00
cfdc2e5d6b
Complete the documentation for relocations.
...
This covers only in-memory storage of relocation records, not object file
relocations.
2011-02-12 15:55:58 +09:00
e19f7e3521
Sort out the parameters for QC style functions :)
2011-02-11 22:29:57 +09:00
01a7af17e5
Beat __obj_exec_class into submission.
2011-02-10 00:15:19 +09:00
d66a441867
Write out the far data space as well as the near.
...
This causes the Objective-QC structs to be emitted now that they havve been
moved to the far data space. Relocs are broken, though.
2011-02-09 21:45:29 +09:00
2d5d8eda5a
Save the caller's address when creating new relocations.

Handle union access now that they're detected properly.
2011-02-08 14:45:48 +09:00

Convert complex types to a suitable low-level type.
...
This takes care of moving structures etc around.

Correct a comment.
2011-02-07 09:56:33 +09:00
76034861c9
Implement direct ivar access in methods.
...
A warning needs to be generated for access to ivars in a class method, but
it seems to work (unable to check due to other errors).
2011-02-07 08:32:52 +09:00
2860a8b28b
enum too is a scalar.
2011-02-06 20:01:55 +09:00
2f7b892452
Fix passing messages to classes.
...
Rename class_pointer_def() to class_pointer_symbol() and use it when a
class name is used as the receiver of a message.
2011-02-06 14:34:40 +09:00
67957a14df
Bring back convert_name(), but siimplified.
...
It is now mainly for converting __FILE__ etc, handling expression symbols,
and checking for undefined identifiers.
2011-02-06 14:29:14 +09:00
d9446c5eb0
Fix builtin methods.

Move the Objective-QC structs from type.c to class.c
2011-02-04 12:07:32 +09:00
d12cdca758
Functions and enums now seem to be working properly.
...
find_type now operates recursively (depth-first) so built up typechains
work as expected.
@overload is treated as a specifier (directly as a storage class, similaar
to typedef).
2011-02-03 10:48:12 +09:00
400abe7fce
Allow freeing of typechains.
2011-02-02 15:15:24 +09:00
1452da676d
Allow types to be built from the outside in.
...
This is required for C style decl processing.
2011-02-02 15:07:44 +09:00

Scan the param list for problems with void.
2011-02-01 21:18:08 +09:00
c53001800a
Create a struct for representing specifiers.
...
The specifiers are yet to come (next few commits), but this will be
necessary when they do.
2011-02-01 21:15:51 +09:00
917c5f08b0
Make a var representing the default type.
...
The default type for vars is integer for ruamoko and float for v6 qc.
2011-02-01 21:12:02 +09:00
834417b8c8
Add "debug" diagnotic printing, and use it.

Debug diagnostics are silent for verbosity levels less than 1.
2011-01-28 13:28:45 +09:00

Add the label to the block to which it refers.
2011-01-28 11:41:53 +09:00
c158b14286
Remove the labels list from the pr struct.
...
I'm not sure they were ever needed.
2011-01-28 11:40:25 +09:00
cdea1d07aa
Produce code for progs.src mode.
...
Separate compilation will take fixing object files.
The generated code is broken due to various relocation fixups being
broken, and float immediates seem to be badly broken.
Debug information is broken too.
2011-01-27 15:44:11 +09:00
a6e65488ec
Remove the "test" parameter from test_expr.
...
The parameter became redundant at some stage.
2011-01-27 08:31:51 +09:00
36c99a8da1
Get function def creation working again.
2011-01-26 14:48:22 +09:00
6ce3c5a59a
Get statments being emitted to the code segment.
...
The first function seems to work fine, but there's a problems with the
scope of params causing params to get their knickers in a twist (tangled
linked list).
2011-01-25 15:46:48 +09:00
fd3b594ca5
Move label relocs to the relevant statement block.
2011-01-25 15:45:31 +09:00
