C: detect more missing semicolons (PR c/7356)
c_parser_declaration_or_fndef has logic for parsing what might be
either a declaration or a function definition.
This patch adds a test to detect cases where a semicolon would have
terminated the decls as a declaration, where the token that follows
would start a new declaration specifier, and updates the error message
accordingly, with a fix-it hint.
This addresses PR c/7356, fixing the case of a stray token before a
#include that previously gave inscrutable output, and improving e.g.:
int i
int j;
from:
t.c:2:1: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'int'
int j;
^~~
to:
t.c:1:6: error: expected ';' before 'int'
int i
^
;
int j;
~~~
gcc.dg/noncompile/920923-1.c needs a slight update, as the output for
the first line changes from:
920923-1.c:2:14: error: expected '=', ',', ';', 'asm' or
'__attribute__' before 'unsigned'
typedef BYTE unsigned char; /* { dg-error "expected" } */
^~~~~~~~
to:
920923-1.c:2:13: error: expected ';' before 'unsigned'
typedef BYTE unsigned char; /* { dg-error "expected" } */
^~~~~~~~~
;
920923-1.c:2:1: warning: useless type name in empty declaration
typedef BYTE unsigned char; /* { dg-error "expected" } */
^~~~~~~
The patch also adds a test for PR c/44515 as a baseline.
