Stephen Heumann fe62f70d51 Add lint option to check for unused variables. 2022-12-12 21:47:32 -06:00
Stephen Heumann 06e17cd8f5 Give an error if file names or command-line parameters are too long.
The source file name, keep name, NAMES= string, and cc= string are all restricted to 255 characters, but these limits were not previously enforced, and exceeding them could lead to strange behavior.

Stephen Heumann 7322428e1d Add an option to print file names in error messages.
This can help identify if an error is in the main source file or an include file.

Stephen Heumann dbe330a7b1 Use centrally-defined token sets to recognize the beginning of declarations. 2020-01-18 15:21:27 -06:00
Stephen Heumann 08b4f8da3e Remove some unnecessary parameters and code.
These are not needed after the refactoring of declaration specifier processing.

Stephen Heumann 6f2eb301e5 Implement C11 _Static_assert mechanism.
This allows code to contain static assertions (checked at compile time).

Stephen Heumann caabb5addf Allow declarations in first clause of for loop (C99). 2018-04-01 16:48:11 -05:00
Stephen Heumann 4cff395745 Move some code from the blank segment to named load segments.
This frees up some space in the blank segment for more static data.

Stephen Heumann 227731a1a8 Allow "static inline" function declarations.
This should give C99-compatible behavior, as far as it goes. The functions aren't actually inlined, but that's just a quality-of-implementation issue. No C standard requires actual inlining.

Non-static inline functions are still not supported. The C99 semantics for them are more complicated, and they're less widely used, so they're a lower priority for now.

The "inline" function specifier can currently only come after the "static" storage class specifier. This relates to a broader issue where not all legal orderings of declaration specifiers are supported.

Since "inline" was already treated as a keyword in ORCA/C, this shouldn't create any extra compatibility issues for C89 code.

Stephen Heumann 90c291808a Always report a non-zero error level when there is an error.
This is necessary to make the "compile" command halt and not process additional source files, as well as to make occ stop and not run the linker.

Previously, this was not happening when the #error directive was used, or when an undefined label was used in a goto.

This addressed the issue with the compco07.c test case.
