This allows for the four combinations of shift and control. Not
bothering with alt because alt-f4 closes my xterm (bbkeys from the looks
of it: it grabs a bunch of Mod1-* keys).
I left the ones below 256 alone (some were necessary anyway), but above
256 they were almost entirely sequential, which rather defeats the
purpose of using an enum, especially since it makes it difficult to
expand sections.
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).
Type encodings are used whenever they are available. For now, if they
are not, then everything is treated as void (which prints <void>, not
very useful). Most return statements and references to .return are now
very readable (excluding structs), and only params going through "..."
are a messy union.
The memset instructions now match the move* instructions other than the
first operand (always int). Probably breaks much, but fixed in next few
commits.
This "pushes" a temp string onto the callee's stack frame after removing
it from the caller's stack frame. This is so builtins can pass
auto-freed memory to called progs code. No checking is done, but mayhem
is likely to ensue if a string is pushed that was allocated in an
earlier frame.
PR_AllocTempBlock() works the same way as PR_SetTempString(), except
that it takes a size parameter and always allocates (never tries to
merge). This is, in a way, abusing the string system, but I needed a way
to allocate a block of progs memory that would be automatically freed
when the current frame ended. The biggest abuse is the need to cast away
the const of PR_GetString()'s return value.
This should speed up ruamoko code somewhat as hash table lookups have
been replaced with direct array indexing. As a bonus, support for
message forwarding has been added (though not tested).
As well as $prefix/include, of course. This fixes the problem with
external ruamoko builds failing due to keys.h and qfcc's "lockdown" on
system headers.
It proved to be too fragile in its current implementation. It broke
pointers to incomplete structs and switch enum checking, and getting it
to work for other things was overly invasive. I still want the encoding,
but need to come up with something more robust.a
Other than consistency with printf(), I'm not sure why we went with the
printed size as the return value; returning the resultant strings makes
much more sense as dsprintf() (etc) can then be used as a safe va()
Other than its blocking of access to certain files, it really wasn't
that useful compared to the functions in qfs, and pointless with access
to qfs anyway.
The progs execution code will call a breakpoint handler just before
executing an instruction with the flag set. This means there's no need
for the breakpoint handler to mess with execution state or even the
instruction in order to continue past the breakpoint.
The flag being set in a progs file is invalid.
The debug subsystem now uses the resources system to ensure it cleans
up, and its data is now semi-private. Unfortunately, PR_LoadDebug had to
remain public for qfprogs because using PR_RunLoadFuncs would cause
builtin resolution to complain.
It is now set to 0 when progs are loaded and every time
PR_ExecuteProgram() returns. This takes care of the default case, but
when setting parameters, pr_argc needs to be set correctly in case a
vararg function is called.
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.
