The master branch has been updated by Andrew Burgess <aburgess@sourceware.org>: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=b6c95c0cc5bd60e2de86d611120bf6191f99860a commit b6c95c0cc5bd60e2de86d611120bf6191f99860a Author: Andrew Burgess <andrew.burgess@embecosm.com> Date: Mon Dec 17 11:21:08 2018 +0000 gdb: Extend the comments in c-exp.y In an attempt to fix PR gdb/13368 this commit adds some comments to c-exp.y which hopefully makes the type parsing code a little clearer. There are no code changes here, so there should be no user visible changes after this commit. gdb/ChangeLog: PR gdb/13368 * c-exp.y (typebase): Extend the comment. (ident_tokens): Likewise.
I think the comment change adequately explained this.
