- I kept getting confused trying to read these instructions, so now their
disassembly looks more MIPS-like:
* All mnemonics have had 'b' prepended to them for "branch".
* The CMP_CHECK bit alters the displayed mnemonic for the inverted
versions. e.g. BEQ can be displayed as BNE.
* The following JMP instruction that encodes the branch destination has
been folded into the disassembly of the branch instruction. Unlike
MIPS, I chose to display it offset from the branch check with =>
instead of another comma.
- Fixed: Don't assume operator new will return a pointer with 16-byte
alignment when allocating a block for the VMFrameStack. Because it seems
it's actually guaranteed to be 8-byte aligned. Don't know where I got
the idea it would always be 16-byte aligned.
- Added versions of the trig operations supported by FLOP that can work
with degrees directly instead of radians.
- Reorder FLOPs into more sensible groupings.
running with the checked VM can be quite slow, since it has asserts everywhere. Some other
fixes were needed before the code actually worked:
- A_CallSpecial needs to have its arguments cast to ints.
- Some functions that set pnum/paramnum directly did not decrement it by 1. This also applies
to A_Jump, though it just uses the value of paramnum instead of changing it.
- Renamed pnum in the PARAM macros to paramnum, since pnum is already used in a few other
places for something different, so this makes searching for it easier.
This has not been tested especially thoroughly, but a first glance seems to indicate success.

Currently, they're only good for disassembly and pasting into a proper text editor
for viewing.
- Fixed some problems with the FxExpression emitters that were revealed by actually
using them on the standard actors.

it isn't even used anywhere yet. In retrospect, I probably should have targeted an intermediate
representation and done codegen with that instead, since that would be something I can reuse.

- Derive PClass from dobject.cpp. This has one major ramification: Since the PClass
is not allocated until runtime, you cannot initialize any static/global data
structures with pointers to PClasses using RUNTIME_CLASS. Attempting to do so
will just initialize with a NULL pointer. Instead, you can initialize using
the address of the pointer returned by RUNTIME_CLASS and dereference that. By
the time you have an opportunity to dereference it, it will no longer be NULL.
- Sync CmakeLists.txt.
- Random fixes for problems GCC spotted.
