Hi TGSI guys mostly :-)
So I'm wondering how circular and perfect tgsi->text->tgsi roundabouts
should be,
Ideally, they should be consistent.
currently the TGSI dump code uses .4f in one place, which makes things
like 1e6 not make it across the divide, I was thinking of dumping
immediates in 32-bit hex format so we know for definite what happens
on the other side,
Yeah, I think we'd have to dump floats as hex to always preserve their
value.
However, I'd like to maintain the readability of float immediates in
dumps. Maybe they could be displayed as a comment. Something like:
IMM[0] FLT32 { 0x...., 0x...., 0x...., 0x.... } # 1.0, 3.0, 2.0, 4.0
I've been thinking of maybe adding a debug option to softpipe to dump
to text and read it back, to see what other regression lie in wait.
Sounds OK to me but it could be a TGSI debug option that would test
dumping + reassembling a shader whenever tgsi_dump() is called.
