If liveness analysis indicates it's good, this should improve the chances of being able to emit the short MAD form.

V2: clarify code, commit msgs, add comments. Drop code to was supposed to make register assignment prefer SDST == SRC2 (patch 2) for now, because it didn't quite do what I intended.

Hi group, I am trying to template a bash script with puppet. Unfortunately, this fails with a bang, and even more unfortunately I have no idea why. The script starts with the usual #!/bin/bash When I run puppet, I get this: info: Caching catalog for l1211022.sdst.sbaintern.de err: Failed to apply catalog: Parameter source failed: Could not understand source #!/bin/bash [... complete script dump ...] ... in neon pink. I tried encapsulating it in <%= "#!/bin/bash" %>, or even in <%= "!" %><%= "#/bin/bash" %>...

Add emission rules for negative and saturate flags for MAD 4-byte opcodes, and get rid of constraints. Short MAD has a very specific SDST == SSRC2 requirement, and since MAD IMM is short notation + 4-byte immediate, don't have the compiler create MAD IMM instructions yet.

Add emission rules for negative and saturate flags for MAD 4-byte opcodes, and get rid of some of the constraints. Obviously tested with a wide variety of shaders.

Add a specific optimisation pass for NV50 to check whether SRC0 or SRC1 is a MOV dst, IMM. If so: fold the IMM in and try to drop the MOV.

was "nv50/ir: PostRaConstantFolding improvements" before. nothing really changed from the last version, just minor things. Karol Herbst (5): nv50/ir: restructure and rename postraconstantfolding pass nv50/ir: implement mad post ra folding for nvc0+ gk110/ir: add LIMM form of mad gm107/ir: add LIMM form of mad nv50/ir: also do PostRaLoadPropagation for FMA

...#39;re allowing saturate/neg emission on the short form. Is this already in envytools? Also, what's the shortForm thing? This change is probably fine, but the changelog needs work.
