2019-03-06test/bench/go1: add go.mod fileBryan C. Mills
cmd/dist executes 'go test' within this directory, so it needs a go.mod file to tell the compiler what package path to use in diagnostic and debug information.

2015-05-21all: retire architecture letter in file names, public APIRuss Cox
This CL removes the remaining visible uses of the "architecture letter" concept. (They are no longer in tool names nor in source directory names.) Because the architecture letter concept is now gone, delete GOCHAR from "go env" output, and change go/build.ArchChar to return an error always. The architecture letter is still used in the compiler and linker sources as a clumsy architecture enumeration, but that use is not visible to Go users and can be cleaned up separately.

Although it was not a primary motivation, this conversion does reduce the wall clock time and cpu time required for make.bash by about 10%.

2012-06-07test/bench/go1: add go/parser benchmarkDave Cheney
As discussed in https://groups.google.com/d/msg/golang-dev/Na9XE6mcQyY/zbeBI7R-vnoJ Here is a static copy of the go/parser benchmark. I ended up using fancy encodings because the original parser.go had a number of `s scattered throughout which made it hard to embed the source directly. Curiously on my laptop this benchmark always scores roughly 10% higher than the standalone benchmark. This may be down to the generation of the fasta data set triggering the cpu governor to raise the cpu speed. However the benchmark is consistent with itself across multiple runs.

We can't depend on init() order, and certainly we don't want to register all future benchmarks that use jsonbytes or jsondata to init() in json_test.go, so we use a more general solution: make generation of jsonbytes and jsondata their own function so that the compiler will take care of the order.
