Catch segfault caused by missing C statements 2021-11-16 22:01:35 -05:00
Andrius Štikonas 185ef7a7c2 Improve handling of compound assignment operators. 
Previously, compound assignment operators were replaced in preprocessor.
This only worked for simple cases where we only had 1-token variable.

This commit switches to proper implementation in the parser.

Andrius Štikonas 511601bcd9 Revert "Add support for pre-increment and pre-decrement operators." 
This reverts commit ab49bcafa4.
 2021-11-13 20:55:11 +00:00
Andrius Štikonas ab49bcafa4 Add support for pre-increment and pre-decrement operators. 
At the moment there is a limitation on only one unary operator,
so things like *++p wouldn't work but ++*p would work.

Add support for &global_variable 2021-01-28 22:22:08 -05:00
Sanne Wouda 0e3d5b609a Add support for global char foo[12]; definitions 
- only enabled in --bootstrap-mode

- allocates space for both the char array and the pointer to the start of
  the array
 2021-01-10 23:01:08 +00:00
Sanne Wouda 49fbe8942f Add error checking for unexpected #endif 2021-01-05 22:56:30 +00:00
Sanne Wouda cd96f65a23 Add macro directives to token_list 
- change the lexer to not remove preprocessor directives
- preprocess() removes any lines starting with a macro directive that it
  doesn't understand (which is currently all of them)
 2021-01-05 22:53:39 +00:00
Sanne Wouda 7b8a99db3c Add a preprocessor-only mode 
- Very useful for testing and debugging
- Add preprocess() stub and skip compilation in preprocessor mode
 2021-01-05 22:53:04 +00:00
Sanne Wouda a18e0c1782 Add newline tokens to parse stream 
- needed to determine start and end of macro directives
- the main parser doesn't need them, so strip out the newline tokens
  before parsing to avoid changing it
