The same code is generated, and readers and static analyzers are
happier.

|
Gets rid of one of the worst strict-aliasing offenders, and actually
produces faster code (at least in some cases, when compiler can use
for instance 64bit moves for memcpy).
(note _mesa_memcpy should get inlined)

The values 2147483648.0 and 4294967294.0 are too larget to be stored in single
precision floats. Forcing these to be singles causes bits to be lost, which
results in errors in some pixel transfer tests.
This fixes bug #22344.

This is a (partial) backport of the signed texture format support in OGL 3.1.
Since it wasn't promoted from an existing extension roll our own.
|
|
add new entrypoints, new texture format, etc
translate in texenvprogram.c for drivers using the mesa-generated tex env
fragment program
also handled in swrast, but not tested (cannot work due to negative texel
results not handled correctly)

Replace use of FLOAT_TO_USHORT with either CLAMPED_FLOAT_TO_USHORT or
UNCLAMPED_FLOAT_TO_USHORT. Same should be done for UBYTE, UINT, etc.
|
|
Rewrite COPY_4FV() macro to not use COPY_FLOAT(), and use integer moves as
originally intended.
|
|
Minor updates/fixes to the source documentation.

stubs with the Open Watcom compiler.

explicit casts and/or tweaking constant and variable definitions.

Moved type conversion and interpolation macros into macros.h
Updated all the files that used to include mmath.h

indicates the read AND draw color buffer for all software rasterization.
Lots of related clean-ups. See RELNOTES-4.1 for details.

Define either MESA_BIG_ENDIAN or MESA_LITTLE_ENDIAN.

FetchTexel routines).
- Initial hooks for GL_EXT_texture_filter_anisotropic.

Added GLvector4us datatype in math/m_vector.[ch]
Added _math_trans_4us() in math/m_translate.[ch]
Choose GLvector4ub, GLvector4us, GLvector4f at compile time based on CHAN_BITS.
Made Driver.ClearColor() and Driver.ClearIndex() optional driver functions.
Changed args to Driver.ClearColor(), updated drivers.
Reordered files in Makefile.X11

that used to require a 'ReducedPrimitiveChange' callback.
Various compilation fixes for XFree86.
Reverted to the older version of glcore.h used internally in XFree86, and
moved it to 'Mesa/include/GL/internal/glcore.h', for compatibility with
XFree86.

New array_cache module
Support 8 texture units in core mesa (now support 8 everywhere)
Rework core mesa statechange operations to avoid flushing on many
noop statechanges.

driver (enable with FX_ALLOW_VTXFMT=t).
|
|
math: Provides basic matrix and vector functionality that
might be useful to multiple software t&l
implementations, and is used by core mesa to
manage the Model, Project, etc matrices.
tnl: The real transform & lighting code from core mesa,
including everything from glVertex3f through vertex
buffer handling, transformation, clipping, lighting
and handoff to a driver for rasterization.
The interfaces of these can be further tightened up, but the basic
splitting up of state and code move is done.
|
|
- Remove support for choosing software fallbacks from core code
- Remove partial fallback code from vbrender.c -- drivers are now
expected to be able to find a triangle/quad function for every state,
even if they have to use _swsetup_Triangle or _swsetup_Quad.
- Marked derived variables in the GLcontext struct with a leading
underscore '_'.
