2017-10-12C/C++: add fix-it hints for various missing symbolsDavid Malcolm29-57/+528
The patch improves our C/C++ frontends' handling of missing symbols, by making c_parser_require and cp_parser_require use "better" locations for the diagnostic, and insert fix-it hints, under certain circumstances (see the comments in the patch for full details). For example, for this code with a missing semicolon: $ cat test.c int missing_semicolon (void) { return 42 } trunk currently emits: test.c:4:1: error: expected ';' before '}' token } ^ This patch adds a fix-it hint for the missing semicolon, and puts the error at the location of the missing semicolon, printing the followup token as a secondary location: test.c:3:12: error: expected ';' before '}' token return 42 ^ ; } ~ More examples can be seen in the test cases. gcc/c-family/ChangeLog: * c-common.c (enum missing_token_insertion_kind): New enum.

2017-10-12C++: avoid partial duplicate implementation of cp_parser_errorDavid Malcolm4-76/+112
In r251026 (aka 3fe34694f0990d1d649711ede0326497f8a849dc, "C/C++: show pertinent open token when missing a close token") I copied part of cp_parser_error into cp_parser_required_error, leading to duplication of code. This patch eliminates this duplication by merging the two copies of the code into a new cp_parser_error_1 subroutine. Doing so removes an indentation level, making the patch appear to have more churn than it really does. The patch also undoes the change to g++.dg/parse/pragma2.C, as the old behavior is restored.
