all: go 1.17 (#197) Bump CI Go versions to 1.16 and 1.17. Update build tags with `go:build` equivalents. Upgrade asmfmt tool for new `go:build` support. Updates #183 2021-10-29 01:18:34 -07:00			`//go:build ignore`
reg: support for register casting Adds methods for referencing sub- or super-registers. For example, for general purpose registers you can now reference As8(), As16(), ... and for vector AsX(), AsY(), AsZ(). Closes #1 2018-12-30 18:40:45 -08:00			`// +build ignore`

build: add attributes argument to TEXT Brings the TEXT() function signature closer to how the directive works in assembly. Also update almost all examples to use NOSPLIT. Closes #11 2019-01-06 20:04:51 -08:00			`TEXT("Split", NOSPLIT, "func(x uint64) (q uint64, l uint32, w uint16, b uint8)")`
