* [dev.inline] cmd/compile/internal/syntax: clean up error and pragma handlingRobert Griesemer2016-12-091-27/+23
| | | | | | | | | | | | | | | | | | | | | | | | | Reviewed in and cherry-picked from https://go-review.googlesource.com/#/c/33873/. - simplify error handling in source.go (move handling of first error into parser, where it belongs) - clean up error handling in scanner.go - move pragma and position base handling from scanner to parser where it belongs - have separate error methods in parser to avoid confusion with handlers from scanner.go and source.go - (source.go) and (scanner.go, source.go, tokens.go) may be stand-alone packages if so desired, which means these files are now less entangled and easier to maintain Change-Id: I81510fc7ef943b78eaa49092c0eab2075a05878c Reviewed-on: https://go-review.googlesource.com/34235 Reviewed-by: Matthew Dempsky <mdempsky@google.com> Run-TryBot: Robert Griesemer <gri@golang.org> TryBot-Result: Gobot Gobot <gobot@golang.org>

| | | | | | | | | | | | | | | - define syntax.Error for cleaner error reporting - abort parsing after first error if no error handler is installed - make sure to always report the first error, if any - document behavior of API calls - while at it: rename ReadXXX -> ParseXXX (clearer) - adjust cmd/compile noder.go accordingly Fixes #17774.
