3c86660d4a [gamecode] Rename MAX_PARMS to PR_MAXPARAMS 2022-01-23 14:17:25 +09:00

2df64384c1 [gamecode] Clean up string_t and pointer_t
They are both gone, and pr_pointer_t is now pr_ptr_t (pointer may be a
little clearer than ptr, but ptr is consistent with things like intptr,
and keeps the type name short).

0bd05c71ac [gamecode] Use unsigned for entity values
I don't know why they were ever signed (oversight at id and just
propagated?). Anyway, this resulted in "unsigned" spreading a bit, but
all to reasonable places.

2b82533526 [gamecode] Add double time state instructions
This has been a long-held wishlist item, really, and I thought I might
as well take the opportunity to add the instructions. The double
versions of STATE require both the nextthink field and time global to be
double (but they're not resolved properly yet: marked with
"FIXME double time" comments).

Also, the frame number for double time state is integer rather than
float.

b544a052bf [gamecode] Bail if PR_SearchDefs is given 0 defs
Fixes the hang when searching for a field in progs that don't have any.

3d62a7f253 [gamecode] Use fuzzy bsearch to find defs by address
The idea is to find th def that contains the address. Had to write my
own bsearch (well... lifted from wikipedia) because libc's is exact. The
defs are assumed to be sorted (which qfcc now ensures when it writes
progs and sym files).

d60291a73e Clean up a lot of va usage
va is not thread-safe (it's not save even without threads), and I want
to be able to run progs in threads.

9bb68f2d8c Allow nested use of PR_SaveParams()
PR_SaveParams() is required for implementing the +initialize diversion
used by Objective-QuakeC because builtins do not have local def spaces
(of course, a normal stack calling convention would help). However, it
is entirely possible for a call to +initialize to trigger another call
to +initialize, thus the need for stacking parameter stashes. As a
bonus, this implementation cleans up some fields in progs_t.

81083698a8 Move to using an in-memory form of ddef_t
This allows the VM to work with extended ddefs transparently. It seems
to have uncovered a typedef alias relocation bug, though.

f5741a979e Implement parameter alignment in the engine
The engine now requires non-v6 progs to store the log2 alignment for the
param struct in .param_alignment.

PR_EnterFunction is clearer and possibly more efficient.

33cbc500e8 Fix a segfault when setting up the stack.
Yup, putting {}s around even single statements under flow control (if, etc)
is a good idea. Wonder if there's a gcc warning for that...

364c2d2c2b Add a stack and push and pop instructions.
The stack is for data, not return addresses.

bc1b483525 Nuke the rcsid stuff.
It's pretty useless in git.

b5019c8e33 Nuke the engine dicrectory from gamecode.
Not the contents, of course :) Anyway, finally, that totally useless
directory is gone.
