89ec86f77f [qfcc] Add option to promote of float through ...
The server code is not yet ready for doubles, especially in its varargs
builtins: they expect only floats. When float promotion is enabled
(default for advanced code, disabled for traditional or v6only),
"@float_promoted@" is written to the prog's strings.

11365024d2 Fix writing of frames files when not requested
I forgot to check for the option for separate compilation.

4df926e531 Write extended ddef information to progs far data
I was originally going to put it in the debug syms file, but I realized
that the data persistence code would need access to both def type and
certainly correct def offsets for defs in far data.

7a399c956b Encode function parameter alignment
The encoding is 3:5 giving 3 bits for alignment (log2) and 5 bits for
size, with alignment in the 3 most significant bits. This keeps the
format backwards compatible as until doubles were added, all types were
aligned to 1 word which gets encoded as 0, and the size is unaffected.

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.

027e76b4c9 Add a doc block to parse_cpp_line.
It took me too long to figure it out :P

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

0585471723 Make defspaces typed.
Simply "backed" and "virutal". Backed spaces have memory allocated to them
while virtual spaces do not. Virtual spaces are intended for local
variables and entity fields.

e3bf64262f Remove the "data" defspace from pr_info_t.
It's only usage would have caused a segfault if it had been hit. I suspect
it's a holdover from before the rewrite of 2011.

4c65d9f2a4 Fix up the definitely lost memory blocks.
qfcc isn't meant to be long running, so I'm not super worried about memory
usage, but definitely lost memory blocks when compiling just a single
function seems a tad sloppy.

1d34da26f7 Add an option to dump frame files.
After running across a question about lists of animation frames and states,
I decided giving qfcc the ability to generate such lists might be a nice
distraction from the optimizer :) Works for both progs.src and separate
compilation. No frame file is generated if no macros have been created.

9691b50f0f Make .type_encodings more useful.
Rather than just a pointer, it is now a struct with a pointer and size
indicating the extent of the type encodings block.

e05c12e16d Make linker_add_def take a pointer for the value.
While it looks like I might not use it for the type encodings, it should be
useful in the future.

fd8c639773 Initialize current_symtab early, with pr.symtab.
This (with the previous commit) fixes the problems with the tags for
builtin structs.

9fd8741b4f Move the state clearing into InitData.
Now, for each compilation, or before linking, only InitData needs to be
called. Fixes the double chaining internal error when compiling and linking
in the same command.

4ef4711c3b Make the type encodings findable.
The base of the type encodings block is given by the .type_encodings def.
The block begins with a "null" type (4 words of 0), followed by the first
type encoding.

At some stage, I will need to add information for extended def information
(32 bit offset, type encoding, other?), but this is good for initial
testing.

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.

7a25283beb Clear out the type encoding def from all types.
The encodings of static types were getting corrupted because their defs
were not necessarily in the same places between compilations when compiling
multiple files.

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).

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.

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).

line number info is now 1 based rather than 0 based (to better detect when

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.

c585a17db9 Give type data a null pointer.
Pointers to the void type descriptor looked just like null pointers and
that was terribly confusing. Avoid that confusion by pre-allocating a
small amount of data in order to reserve space for a null descriptor.

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.

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.
