[Mesa-dev] scons tnl bug, rfc on removing mesa rtasm.

[Alexander von Gluck]

So I've been digging through the assertion error I am getting under Haiku 
and have finally found the issue...

The Mesa tnl depends on the Mesa rtasm header (mesa/x86/rtasm/x86sse.h), 
however scons never compiles mesa/x86/rtasm/x86sse.c into libmesa.  As 
x86/rtasm/x86sse.c is never compiled in, libmesa tnl requires libgallium.a to 
link into the gallium rtasm code.

As the header in mesa/x86/rtasm/x86sse.h doesn't match the Gallium rtasm 
symbols (src/gallium/auxiliary/rtasm/rtasm_x86sse.h), we begin getting 
assertion errors as heap is corrupted (mostly when tnl is used)

I am playing with fixing this by making tnl rely on gallium's rtasm vs the 
Mesa one.  As tnl is the last thing I can find that uses the Mesa rtasm... 
mesa rtasm (http://cgit.freedesktop.org/mesa/mesa/tree/src/mesa/x86/rtasm) 
could even be removed if this works.

Does anyone know of any implementations of Mesa this may break?

  Thanks!
