Clear the statement line buffer
...
The problem with moving to a cached buffer is it needs to be cleared.
Fixes the weird output of qfprogs and tracing (not missing local defs,
though).

[gamecode] Remove all use of va
...
With this, the VA is very close to being safe to use in a threaded
environment (so long as each VM is used by only one thread). Just the
debug file hash and source paths to sort out.

Add a breakpoint flag to opcodes
...
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.

Relocate local def type encodings in debug load
...
For technical reasons (programmer laziness), qfcc does not fix up local
def type encodings when writing the debug symbols file (type encoding
location not readily accessible).
2020-02-25 20:46:01 +09:00
Bill Currie
89e83d7d73
Move the debug info out of progs_t
...
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.

Improve handling of pr_argc
...
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.

Allow progs num_edicts and reserved_edicts to be null

probably not be in the VM itself.

Ensure edict_parse is reset on progs load

A server switching from a game that sets edict_parse to one that does

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.

Strangely enough, using the progs resources system. This is a step
towards having progs that can be reset properly, or even dynamically
created VMs.

Implement parameter alignment in the engine

The engine now requires non-v6 progs to store the log2 alignment for the

PR_EnterFunction is clearer and possibly more efficient.
