This copies over a dummy builtin_functions.cpp and rebuilds a
bootstrapped version of the compiler, then uses that to generate the
proper list of builtins. Finally, it rebuilds the compiler with the new
list.
Unfortunately, it's no longer automatic, but at least it works.
|
|
Each language version/extension and target now has a "profile" containing
all of the available builtin function prototypes. These are written in
GLSL, and come directly out of the GLSL spec (except for expanding genType).
A new builtins/ir/ folder contains the hand-written IR for each builtin,
regardless of what version includes it. Only those definitions that have
prototypes in the profile will be included.
The autogenerated IR for texture builtins is no longer written to disk,
so there's no longer any confusion as to what's hand-written or
generated.
All scripts are now in python instead of perl.

This would have been included in commit 23f6017d, but make wisely did
not regenerate the file when the .lpp file did not change.

With the glsl2-965 branch, the optimization of glsl-algebraic-rcp-rcp
regressed due to noop swizzles hiding information from ir_algebraic.
This cleans up those noop swizzles for us.
|
|
This one is a little tricky because of the LHS handling.
|
|
I keep copy and pasting this code all over, so consolidate it in one
place.

This lets drivers override ir_to_mesa with their own codegen, or at
least have a native alternative.
|
|
|
|
These are passes that we expect all codegen to be happy with. The
other lowering passes for Mesa IR are moved to the Mesa IR generator.

In C++ you don't have to say 'struct' or 'class' if the declaration of
the type has been seen. Some compilers will complain if you use
'struct' when 'class' should have been used and vice versa.
Fixes bugzilla #29539.

This is the patch from Benjamin's Aug 11, 2010 email with minor fixes
(such as moving declarations before code)

Also remove the --never-interactive command line option for the
preprocessor lexer. This was already done for main compiler lexer.
|
|
If gl_Vertex is not used in the shader, then attribute location 0 is
available for use.
Fixes piglit test case glsl-getattriblocation (bugzilla #29540).

This is based on a patch by nobled <nobled@dreamwidth.org> and allows the TFP
extension to be enabled for DRISW also. This patch does not enable TFP for DRISW
though, because testing on xephyr segfaults here (for both classic and gallium):
Program received signal SIGSEGV, Segmentation fault.
0x00786a4a in _mesa_GenTextures (n=1, textures=0xbfffee4c) at main/texobj.c:788
788 ASSERT_OUTSIDE_BEGIN_END(ctx);
(gdb)
(gdb) where
\#0 0x00786a4a in _mesa_GenTextures (n=1, textures=0xbfffee4c) at main/texobj.c:788

\#2 0x08168498 in __glXDispatch ()
\#3 0x0808b6ce in Dispatch ()
\#4 0x08084435 in main ()
The TFP code is generic except for the teximage call. We need to verify that
DRISW correclty implements whatever hook teximage finally calls.

MAT2 and MAT2X2, for example, are treated identically by the parser.
The language version based error checking (becuase mat2x2 is not
available in GLSL 1.10) is already done in the lexer.

It doesn't work well with Hyper-Z, so put the burden on the state tracker.

This always restores the previous depth clear value after CBZB clear.

These values are what fglrx returns.

It breaks Regnum Online in that it renders random triangles

This patch fixes the MinGW build.

I noticed gears memory usage was heading skywards, some r600 "states"
aren't properly refcounted, and the ctx->state is never freed.
