Also changed all "if (this==NULL) return;"s.
Fixes some -Wtautological-undefined-compare warnings.
Quoting Clang:
"'this' pointer cannot be null in well-defined C++ code; comparison may
be assumed to always evaluate to false"
except for EntitiesMP/Fish.es which I'm not sure about, and in
Computer.cpp the weird "if (_iActiveMessage < _acmMessages.Count()==0)"
construct whichs intention I didn't fully grasp, either.
many unused functions and variables are now commented out
You'll still get tons of warnings, which should mostly fall in one of
the following categories:
1. Unnecessary variables or values generated from .es scripts
2. Pointers assigned to from functions with side-effects: DO NOT REMOVE!
Like CEntity *penNew = CreateEntity_t(...); - even if penNew isn't
used, CreateEntity() must be called there!
Fixed -Wreorder warnings (hopefully the last?), also several potentially
uninitialized variables.
In SetupPixelFormat_OGL() Assert if gap_iDepthBits ends up being 0.
Small adjustments to cmake warning settings for gcc/clang
The code used to store the world pointer as a console variable
"pwoCurrentWorld" of type INDEX (int32) - that won't work for 64bit, so
I added CShell::SetCurrentWorld() and CShell::GetCurrentWorld() and
store it as a pointer.
introduced PLATFORM_32BIT and PLATFORM_64BIT macros, so you can do
#ifdef PLATFORM_64BIT if you need to.
I needed that for CDrawPort::GetID() to properly CRC a pointer.
Also added a sanity check in Engine/Base/Types.h that makes sure that
uintprt_t and size_t have the same size, as the code uses size_t to
store pointers (or cast from pointer to int) all over the place.
Made some "tags" from Engine/Templates/BSP_internal.h size_t instead of
ULONG - they're used to store pointers to identify vertices and such,
so they'd better be big enough to actually store a pointer.
Some more are still missing.
Touches a lot of code to remove long constants like "1L", so this patch is
large and ugly, but I think it makes all those Clamp() calls look nicer in
the long run.
Most of the game is 64-bit clean, since we can build without assembly code
now. I've marked the things that are obviously still wrong with STUBBED lines.
That being said: a 64-bit build can already run the demos mostly correctly,
so we're actually almost there!
There are a few obvious things that are obviously wrong, to be fixed.
* Only use ENOSR and ENOPKG if defined
ENOSR and ENOPKG are part of the POSIX optional STREAMS extension, and
are not available on most other platforms than GNU/Linux.
* Support building on other GNU platforms than Linux
Build for other GNU platforms the same way as Linux: this includes
CMAKE_SYSTEM_NAME "GNU" (GNU/Hurd) and "GNU/kFreeBSD" (GNU/kFreeBSD).
This was a _ton_ of changes, made 15 years ago, so there are probably some
problems to work out still.
Among others: Engine/Base/Stream.* was mostly abandoned and will need to be
re-ported.
Still, this is a pretty good start, and probably holds a world record for
lines of changes or something. :)
