Rangi a47da5f71f Deprecate __FILE__ and __LINE__ (#1072) 
Unlike C, these constants are not convenient for logging in macros,
since they always report the same data (their location in the macro).

RangiandISSOtm 11a6a81169 Implement -Wtruncation=level (#931) 
* Implement -Wtruncation=level

-Wtruncation=0 is the same as the current -Wno-truncation.
-Wtruncation=2 is the same as the current -Wtruncation.
-Wtruncation=1 is the new default; it's less strict, allowing
N-bit values to be between -2**N and 2**N (exclusive).

* Implement generic "parametrized warning" system

* Test more `Wtruncation` variants

is compatible with it.

Rangi 9923fa3eee Fix expansions that start from the end of another expansion (#839) 
Do not free an expansion until its offset is *past* its size.
This means potentially freeing a nested stack of expansions
all at once.

Fixes #696
 2021-04-17 13:14:40 -04:00
Rangi ee5da4468d Fix interpolation/STRFMT overflow issues (#838) 
Widths and fractional widths greater than 255 would overflow a
uint8_t and wrap around to smaller values.

Total formatted lengths greater than the avilable buffer size
would overflow it and potentially corrupt memory.

Fixes #830
Closes #831

Rangi 5c852c7651 Store the nested expansions starting from the deepest one (#829) 
This shortens the lexer by 100 lines and simplifies
access to expansion contents, since it usually needs the
deepest one, not the top-level one.

Fixes #813

Rangi e7d6ddf593 Fix linking tiny overlay files (#755) 
* Fix compatibility of rgblink -O and -t

The -t "tiny mode" option makes ROM0 cover 0x8000 bytes,
not 0x4000. The -O "overlay" option fills areas uncovered
by sections with data from an overlay file. These needed
to cooperate so that the calculated uncovered overlay size
does not exceed the actual size of the ROM.

Fixes #754

* Print link test names like asm tests do

* Make the three test.sh scripts more similar

Rangi a6d844a9a5 Add more test cases for IF, REPT, and MACRO (#748) 2021-02-19 19:34:21 -05:00
Rangi d049ffc0f0 Handle string literals within macro arguments (#685) 
Fixes #683 and #691

The lexer's raw mode for reading macro args already attempted
to handle semicolons inside string literals, versus outside ones
which start comments. This change reuses the same function for
reading string literals in normal and raw modes, also handling:

- Commas in strings versus between macro args
- Character escapes
- {Interpolations} and \1-\9 args inside vs. outside strings
- Multi-line string literals

Macro args now allow escaping '\', '"', and '\\'.

A consistent model for expanding macro args and interpolations,
within macro args, string literals, and normal context:

- "{S}" should always equal the contents of S
- "\1" should always act like quoting the value of \1
