Currently translate_sse puts two trivial wrappers in the translate vtable.
These slow it down and enlarge the source code for no gain, except perhaps
the ability to set a breakpoint there, so remove them.
Breakpoints can be set on the caller of the translate functions, with no
loss of functionality.
Changes in v3:
- If we can do a copy, don't try to get an emit func, as that can assert(0)
Changes in v2:
- Add comment regarding copy_size
When used in GPU drivers, translate can be used to simultaneously
perform a gather operation, and convert away from unsupported formats.
In this use case, input and output formats will often be identical: clearly
it would make sense to use a memcpy in this case.
Instead, translate will insist to convert to and from 32-bit floating point
numbers.
This is not only extremely expensive, but it also loses precision for
32/64-bit integers and 64-bit floating point numbers.
This patch changes translate_generic to just use memcpy if the formats are
identical, non-blocked, and with an integral number of bytes per pixel (note
that all sensible vertex formats are like this).
Triangle strip alternates the front/back orientation of its triangles.
max_vertices was made even so that varray never splitted a triangle
strip at the wrong positions.
It did not work with triangle strips with adjacencies. And it is no
longer relevant with vsplit.
vcache decomposes primitives while vsplit splits primitives. Splitting
is generally easier to do and is faster. More importantly, vcache
depends on flatshade_first to decompose. The outputs may have incorrect
vertex order which is significant to GS.
vsplit is based on varray. It sets the split flags when a primitive is
splitted. It also has support for indexed primitives.
For indexed primitives, unlike vcache, vsplit splits the primitives
instead of decomposes them.
A primitive may be splitted in frontends. The splitted primitives
should convey certain flag bits so that the decomposer can correctly
decide the stipple or edge flags.
This commit adds flags to draw_prim_info and updates the decomposer to
honor the flags. Frontends and middle ends will be updated later.
'struct dd_function_table' only conditionally contains
the function pointer NewFramebuffer and friends based on
FEATURE_EXT_framebuffer_* defines. (See src/mesa/main/dd.h)
Fixes the build when the features are disabled and the vfuncs
don't exist.

Remove slang_compile.h.
Include glheader.h for GL symbols.
Include slang_compile_function.h for slang_function_scope symbol.
Include slang_compile_struct.h for slang_struct_scope symbol.
Include slang_compile_variable.h for slang_variable_scope symbol.
Include slang_typeinfo.h for slang_type_specifier symbol.
Include slang_utility.h for slang_atom_pool symbol.
This changes r300_destroy_context() so it can be called
on a partially-initialized context, and uses it when
r300_create_context() hits a fatal error.
This makes sure r300_create_context() doesn't leak memory
or neglect to call r300_update_num_contexts() when it fails.

This fixes a potential bug if (has_hyperz) is false
(it would still init the atom as if has_hyperz were true).

For 16 and 64 pixel levels, calculate a mask which is linear in x and
y (ie not in the swizzle layout).
When iterating over full and partial masks, figure out position by
manipulating the bit number set in the mask, rather than relying on
postion arrays.
Similarly, calculate the lower-level c values from dcdx, dcdy and the
position rather than relying on the step array.
