MakePos creates a new Pos value with the given base, and (file-absolute) line and column.

NewFileBase returns a new *PosBase for a file with the given (relative and absolute) filenames.

NewInliningBase returns a copy of the old PosBase with the given inlining index.

NewLinePragmaBase returns a new *PosBase for a line directive of the form //line filename:line:col /*line filename:line:col*/ at position pos.

Default; position is not a statement boundary, but might be if optimization removes the designated statement boundary.

Position is a statement boundary; if optimization removes the corresponding instruction, it should attempt to find a new instruction to be the boundary.

Position should not be a statement boundary, but line should be preserved for profiling and low-level debugging purposes.

NoPos is a valid unknown position.

NoXPos is a valid unknown position.

A Pos encodes a source position consisting of a (line, column) number pair and a position base.

A PosBase encodes a filename and base position.

A PosTable tracks Pos -> XPos conversions and vice versa.

XPos is a more compact representation of Pos.
