Even though the spec says that the limits should be -64/+63, proprietary
drivers support much larger relative offsets and some applications do
depend on this non-standard behavior.
Also program_parse.tab.c has been regenerated.
This fixes the parser error:
ARB_vp: error: relative address offset too large
See also: https://bugs.freedesktop.org/show_bug.cgi?id=28628
4096 * sizeof(vec4) is the maximum size of the constant buffer on NV50.
It is not supposed to be a definite hardware limit, it is for the parser
not to get in the way and let the underlying driver decide whether it can
run the shader or not.

mtypes.h does not use any symbols from compiler.h.
Also add the required headers for files that depended on symbols from
compiler.h but were indirectly including compiler.h through mtypes.h.

Now drivers, etc. can know which register files are accessed with
indirect addressing. Before we just checked gl_program::NumAddressRegs
but didn't know if that was the constant buffer, temp regs, or what.
The only user of this new field so far will be the gallium state tracker.
|
|
Don't rely on inclusion of other files that already include macros.h.

Based on the two recent changes to program_lexer.l.
|
|
This avoids two "function defined but not used" warnings. For the yyinput
function we define YY_NO_INPUT which tells flex to simply not generate this
function.
For unput, we add a call to this function, but inside a while(0) so
that it will quiet the warning without actually changing any
functionality.
|
|
Add declarations for two functions generated in the flex ouput. It
would be nicer if flex simply declared these generated functions as
static, but for now we can at least avoid the warning this way.

just like in Gallium it's a basic functionality needed by a lot
of modern graphcis extensions
|

laying down the foundation for everything and implementing most of the
stuff.
linking, gl_VerticesIn and multidimensional inputs are left.
