  "message": "cmd/compile: fix misscompile in rewrite generic rules\n\nWe canonicalize *sh*x(32|16|8) x (Const*) to *sh*x64 x (Const64)\nhowever for the shift type we were using the shift\u0027s type.\n\nThis is wrong since if we have let\u0027s say Rsh32x32 \u003cuint32\u003e\nwe would generate a Const64 with a type size of 4 (given it\ntakes the uint32 type).\n\nThis causes me confirmed crashes, maybe misscompilations too but\nI didn\u0027t tried coming up with one.\n\nChange-Id: Idcef7a371836524aa6649e13424431d716497860\nReviewed-on: https://go-review.googlesource.com/c/go/+/795240\nAuto-Submit: Jorropo \u003cjorropo.pgm@gmail.com\u003e\nAuto-Submit: Junyang Shao \u003cshaojunyang@google.com\u003e\nReviewed-by: Keith Randall \u003ckhr@golang.org\u003e\nLUCI-TryBot-Result: golang-scoped@luci-project-accounts.iam.gserviceaccount.com \u003cgolang-scoped@luci-project-accounts.iam.gserviceaccount.com\u003e\nReviewed-by: Keith Randall \u003ckhr@google.com\u003e\nReviewed-by: Junyang Shao \u003cshaojunyang@google.com\u003e\n",
