similar to: [PATCH 1/3] nv50/ir: Add support for MAD short+IMM notation

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.

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.

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

OK, so there's a bunch of stuff in here. The geometry stuff is based on the work started by Bryan Cain and Christoph Bumiller. Patches 01-12: Add support for geometry shaders and fix related issues Patches 13-14: Make it possible for fb clears to operate on texture attachments with an explicit layer set (as is allowed in gl 3.2). Patches 15-17: Make ARB_texture_multisample work

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

And you'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.

tgsi_default_instruction_memory / tgsi_build_instruction_memory were returning uninitialized memory for tgsi_instruction_memory.Texture and tgsi_instruction_memory.Format. Note 0 means not set, and thus is a correct default initializer for these.

Could you please get rid of the cosmetic changes (eg. the switch ones)? Because this doesn't really improve readability and in my opinion these changes should be eventually done in a separate patch. Other than that, this patch is : Reviewed-by: Samuel Pitoiset <samuel.pitoiset at gmail.com> Yes, this probably won't work as is for atomic operations but the lowering pass is

This approach leads to the emitters needing to know about both global and buffer, even though at that point, they are identical. I was thinking that in the lowering logic, buffer would just get rewritten as global (with the offset added), thus not needing any change to the emitters. What do you think about such an approach?

Gracias, Carlos. Habia pensado en algo similar usando sapply(): sapply(seq(1, ncol(vtmp), by = 2), function(i) c(rbind(as.character(vtmp[, i]), as.character(vtmp[, i+1])))) Dependiendo de la dimension de los datos, quizas mapply() sea mas eficiente que sapply().

Excelente! Ahora corre muy rápido. No conocía ese método, creo que me va a resultar muy útil. Muchas gracias y saludos. Fernando Macedo El 24/02/15 a las 10:51, Jorge I Velez escribió: Fernando, Podrias intentar R> a <- rep('a', 5) R> b <- rep('b', 5) R> a [1] "a" "a" "a" "a" "a" R> b [1] "b"

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.
