It seems the code expected octal escapes to always start with 0. This is
not the case. Also, octal escapes are limited to 3 digits (and hex to 2).
This fixes the garbled bold text in ITS.
It was properly cleared after drawing water chains and sky chains, but I
had missed normal surfaces. It took the use of the same texture for both
normal surfaces and water surfaces to trigger the bug. Thanks go to Simon
'Sock' O'Callaghan and his In The Shadows mod.
This fixes the infinite loop in Sock's shadows mode. Thanks to Spike for
helping me with what should be happening. However, we're still uncertain
about just how the thinktime/sv.time logic should behave.
vidmode is starting to show its age. Modern X doesn't need a config file,
and when one is not available, the list of available resolutions is quite
strange. Time to look into randr support.
It turns out gcc on little endian machines didn't guarantee the type of
ShortNoSwap due to it being a macro that just returned its parameter. At
the same time, LongNoSwap and FloatNoSwap have been fixed.
The bsp2 header is not necessarily correct (or even present), but the bsp29
header is: it was setup via set_bsp32_write. This fixes the bsp corruption
when vising a map (and, I expect, any problems with qfbsp on a big-endian
machine).
Since the hull depth needs to be set for the hull to be useful, it makes
sense to move the code into the same place that allocates new hulls (to me,
anyway).
MOVEP's opc itself is always known and used, whether it's a constant
pointer or variable doesn't matter. This fixes the lost pointer calculation
for va_list.list[j] = object_from_plist (item);
Dead nodes are those that generate unused values (unassigned leaf nodes,
expressions or destinationless move(p) nodes). The revoval is done by the
flow analysis code (via the dags code) so that any pre and post removal
flow analysis and manipulation may be done (eg, available expressions).
assign_expr mangles the destination expression for dereferenced
assignments into something that is invalid as an lvalue, so simply use
new_binary_expr with the same opcode.
It turns out expression trees are (mostly?) valid DAGs, so all edges being
constrained works, though the graphs get a little tall (but easier to read).
This fixes the infinite loop in if ((x = self.heat && x))
Really, I think I need to revisit the whole expression tree code. It's
proving to be rather fragile.
The source of the assignment is used as the value to test, and the
assignment itself is inserted into the boolean expressions's block. This
fixes the inernal error for "if ((x = 0))".
Normally, it will happen only as a follow-on error, but I can think of a
way to force it without other errors, so treating it as an internal error
is a bit harsh.
