How the ... is it using 1000 TEMPs ?
Wait, does it have large arrays and are they accessed indirectly ?

Can you implement* an INDEXABLE_TEMPORARY file instead so we can use
TGSI_FILE_TEMPORARY_ARRAY so that I can finally support this in nv50
without having to spill my whole GPR file to memory because I don't
know what part of TEMP can be accessed by the indirect load/store ?

Kthxbye :-)

* or wait for someone (possibly me, but unlikely) to implement ...
might be nicer, but, I'm not really objecting to the patch
