Unfortunately, this restriction means that if we want to\nunion two environment sets, we may need to multiply factors out in\norder to normalize the result into this restricted representation. In\nsome cases, this can result in exponential blowup. For example, if\nthere are nested sums, then the environment will contain bindings of\nvariables that don\u0027t matter for whole branches of the value\nexpression, but that still participate when constructing the union of\nenvironment sets. These dead variables wind up expanding the\nenvironment representation exponentially, even though they have no\neffect.\n\nTo fix this, we lift this restriction. Now, a nonDetEnv is an\narbitrary algebraic expression of unions and cross-products. This is\nactually much simpler, implementation-wise, and addresses this\nexponential blowup problem.\n\nWe add a stress test demonstrated nested sums that prior to this\nchange required 12 GB of RAM and took 20 seconds to unify.

"message": "internal/simdgen: introduce instruction variants and use for masked ops\n\nIn AVX-512, nearly all operations take a mask, but it\u0027s optional.\n\nCurrently, the XED loader produces only the masked form of these\ninstructions. Since this mask is one of the input operands, the Go\ndefinitions YAML needs a separate entry to match the masked form. To\ngenerate both the masked and unmasked forms, we unify only the masked\nform and then when generating the Go API we recognize this and\nduplicate the operation in unmasked form. Unfortunately, since\npre-AVX-512 operations never have this mask input, we wind up\nduplicating many unifier definitions to match both the pre-AVX-512 and\nAVX-512 forms, even though the unmasked operation produced during API\ngeneration looks like a pre-AVX-512 definition.\n\nTo fix all this, we flip things around. Instead of generating the\nmasked and unmasked variants at API generation, we generate them much\nearlier, during XED loading. The XED data already contains a clear\nmarker for which masks are optional (it\u0027s wrong in a few cases, which\nwe work around). For instructions with an optional mask, the XED\nloader now generates both the masked and unmasked forms.\n\nThen, to make both easy to match, we put the mask operand into a new\ntop-level tuple called \"inVariant\". This way, a single unifier def can\nmatch the pre-AVX-512 instruction, and the masked and unmasked AVX-512\ninstructions.\n\nWhen we load the results of unification for generating the API, we do\nsome light canonicalization of the operation. We append any inVariant\noperands to the input operands list; and if there\u0027s a mask in\ninVariant, we append \"Masked\" to the Go method name.\n\nWith all of this done, we can delete all of the \"*Masked\" forms of\noperations from the YAML. In a few cases, we have to merge some\ninformation from the masked form into the unmasked form. For\noperations that were introduced in AVX-512, we currently *only* have\nthe Masked form; so for these we keep the definition but strip out the\nmasking.\n\nThis ultimately has very little effect on the generated API. In a few\ncases it fills in holes that let us pick a better instruction. It\nfixes some doc strings that got duplicated incorrectly between masked\nand unmasked forms.\n\nThis change makes it much easier to write other tools besides the Go\nAPI generator because it moves nearly all masking logic out of\nwriteGoDefs. It also eliminates some fragile Operation duplication\nlogic from writeGoDefs. I plan to move a few more things out of the Go\nAPI generator, but this is definitely the big one.\n\nChange-Id: I17ee70cff15a80e8025eec96a7286266233546d9\nReviewed-on: https://go-review.googlesource.com/c/arch/+/691341\nAuto-Submit: Austin Clements \u003caustin@google.com\u003e\nReviewed-by: David Chase \u003cdrchase@google.com\u003e\nReviewed-by: Junyang Shao \u003cshaojunyang@google.com\u003e\nLUCI-TryBot-Result: Go LUCI \u003cgolang-scoped@luci-project-accounts.iam.gserviceaccount.com\u003e\n" }, { "commit": "ce2e40c7d7dfb66cde2d1e77ce2ed27b1714d1b1", "tree": "2b85b1dbe08d0730ee27a012026067e549e42fd5", "parents": [ "63d3a519a5d6f506b1593ca7a2aa980362a0bc44" ], "author": { "name": "Austin Clements", "email": "austin@google.com", "time": "Fri Jul 25 17:31:06 2025 -0400" }, "committer": { "name": "Gopher Robot", "email": "gobot@golang.org", "time": "Tue Jul 29 12:23:21 2025 -0700" }, "message": "internal/simdgen: use \"NAME\" for method names in doc strings\n\nThis will let us merge operations that differ only in their method\nnames.
