--- Comment #1 from Keith Kriewall <keith.kriew...@attachmate.com> ---
I've run into this with Mesa 9.0.2 and LLVM 3.2. It appears that the bitfields
in the prog_src_register struct (/src/mesa/program/prog_instruction.h) do not
translate correctly to the src_register() parameter types. A workaround is to
remove the bitfield (:<size>) specifications in the prog_src_register struct.
In translate_src(), the following call ..
struct ureg_src src = src_register( t, SrcReg->File, SrcReg->Index );
.. with the following data ..
t 0x0458d958 {ureg=0x03c51258 temps=0x0458d95c constants=0x03c5c3a8
...} st_translate *
SrcReg 0x03c597bc {File=0x00000001 Index=0x00000400 Swizzle=0x00000249 ...}
const prog_src_register *
File 0x00000001 unsigned int
Index 0x00000400 int
.. results in the following parameters to src_register():
> opengl32.dll!src_register(st_translate * t=0x0458d958, gl_register_file
> file=0x03c7dd54, int index=0xf78cdac8) Line 227 + 0x11 bytes C
You can see that 't' is passed correctly, but the bitfields for SrcReg->File
and SrcReg->Index have not.
I tried compiling LLVM and Mesa with all optimizations turned off, with no
change. (The debug build does not fail in this way, only the release build.)
