Robert Griesemer 2a5cf48f91 cmd/compile: print columns (not just lines) in error messages ... Compiler errors now show the exact line and line byte offset (sometimes called "column") of where an error occured. For `go tool compile x.go`: package p const c int = false //line foo.go:123 type t intg reports x.go:2:7: cannot convert false to type int foo.go:123[x.go:4:8]: undefined: intg (Some errors use the "wrong" position for the error message; arguably the byte offset for the first error should be 15, the position of 'false', rathen than 7, the position of 'c'. But that is an indepedent issue.) The byte offset (column) values are measured in bytes; they start at 1, matching the convention used by editors and IDEs. Positions modified by //line directives show the line offset only for the actual source location (in square brackets), not for the "virtual" file and line number because that code is likely generated and the //line directive only provides line information. Because the new format might break existing tools or scripts, printing of line offsets can be disabled with the new compiler flag -C. We plan to remove this flag eventually. Fixes #10324.
