* encoding/binary: document the new bool supportBrad Fitzpatrick2016-12-011-1/+4

* encoding/binary: add bool supportBlixt2016-09-281-3/+51
| | | | | | | | | | | | | This change adds support for decoding and encoding the bool type. The encoding is a single byte, with a zero value for false and a non-zero value for true. Closes #16856.

* all: remove unnecessary type conversionsMatthew Dempsky2016-04-151-1/+1
| | | | | | | | | | | | | cmd and runtime were handled separately, and I'm intentionally skipped syscall. This is the rest of the standard library. CL generated mechanically with github.com/mdempsky/unconvert.

* cmd/compile: extend prove pass to handle constant comparisonsKeith Randall2016-03-311-12/+12
| | | | | | | | | | | | | | | | Find comparisons to constants and propagate that information down the dominator tree. Use it to resolve other constant comparisons on the same variable. So if we know x >= 7, then a x > 4 condition must return true. This change allows us to use "_ = b[7]" hints to eliminate bounds checks.

| | | | | | | | | | The inserted early bound checks cause the slice to expand beyond the original length of the slice.

| | | | | | | | | | | | | | | * This the simplest solution I could came up with that doesn't required changing the compiler. * The bound checks become constants now so they are removed during opt phase.

* all: make copyright headers consistent with one space after periodBrad Fitzpatrick2016-03-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | This is a subset of https://golang.org/cl/20022 with only the copyright header lines, so the next CL will be smaller and more reviewable. Go policy has been single space after periods in comments for some time. The copyright header template at: https://golang.org/doc/contribute.html#copyright also uses a single space. Make them all consistent.
