The code in the C grammar is generated by yacc and is not checked by
lint's strict bool mode, therefore the replacement was done manually.
No change to the resulting change.
My previous commit message was wrong in saying that the '%prec' was
necessary. It is not necessary.
Most probably I misspelled the name of the grammar rule as opt_comma
instead of comma_opt, which would lead to the same number of conflicts
in the grammar plus a warning, but no build failure.
The '%prec T_COMMA' is necessary to avoid lots of parse errors in the
lint1 unit tests. Curiously, further down in the grammar, for compound
literals, the '%prec T_COMMA' is not necessary, even though the context
looks very similar.
No functional change.
Previously, the grammar syntactically accepted the following code:
int var = .member = 12345;
The designation '.member =' can only be used with brace-enclosed
initializers.
In d_c99_init.c, the initialization of array_with_designator failed.
The designator '.member' from that initialization was not cleaned up
before starting the next initialization.
These two functions are supposed to model the designator that is used
for initializing structs and arrays. The implementation is still buggy
and does not work at all for C99 designators with multiple names, see
d_init_pop_member.c.
For now, just rename the functions to head in the right direction.
No functional change.
The operator NAME has the name 'name', therefore no special case is
needed.
Having the words 'with type' in the message makes the message easier to
find from the debug log. Given that the operator name is used unquoted,
the log message 'name: int value=111' was nearly impossible to find in
the code.
Replace the '()' with an actual word, to avoid any confusion about
whether the type name might be a function type without prototype.
Reduce the amount of '=' signs, instead use commas to separate the
properties of the node.
No functional change outside debug mode.
The previous name could be too easily confused with the type qualifier
'const'. The operator name is mainly used in the debug log, only
occasionally in the output. Since 'constant' is not a "real" operator,
it probably doesn't occur in messages at all.
