ISSOtm ed4a613473 Rename productions to "reloc" when not really constant 2020-02-11 19:04:35 +01:00
ISSOtm 112098514d Fix 1 s/r and 1 r/r conflict 
Implements the fix suggested [here](https://github.com/rednex/rgbds/issues/44#issuecomment-69360499), which performed better than expected!
I'm not \*too\* fond of this but this seems like the right way

ISSOtm 31aa1ea474 Improve arg-shift test 
New test case courtesy of @aaaaaa123456789
 2020-02-11 11:38:57 +01:00
ISSOtm 96b6e4a76e Add forgotten semicolon in grammar 2020-02-11 11:36:50 +01:00
ISSOtm 001b95d12a Add SHIFT with numeric argument 
Fixes #442.
 2020-02-11 11:25:38 +01:00
ISSOtm 3b2c862320 Make more RGBASM errors print their line number 
Fixes #379.
 2020-02-11 09:35:19 +01:00
ISSOtm 230f849229 Fix error output slightly broken on Windows 
Apparently, `perror` on Windows forces a newline before itself, which is
not the behavior intended. Instead, print the error message inline.

Eldred Habert c37253fe5a Merge pull request #480 from ISSOtm/section 
Improve section management
 2020-02-11 08:51:00 +01:00
Eldred Habert 0ed8d3859d Merge pull request #481 from rednex/revert-451-atomic_output

 2020-02-11 08:32:27 +01:00
ISSOtm 6963d77f8a Add documentation for LOAD blocks 2020-02-10 09:30:33 +01:00
ISSOtm 02ea52f453 Add test for LOAD 2020-02-10 03:39:09 +01:00
ISSOtm cdabc057a0 Allow unseekable files with INCBIN 
Go figure the use case, but the feature is there now
 2020-02-10 03:39:09 +01:00
ISSOtm eb0d75711a Implement LOAD/ENDL blocks 
Basically implements and closes rednex#274.
 2020-02-10 03:39:09 +01:00
ISSOtm f121119283 Use section's offset instead of general one 
That's more future-proof and makes more sense
 2020-02-10 03:37:44 +01:00
ISSOtm d9c1b66931 Deduplicate value output function code 2020-02-10 03:37:43 +01:00
ISSOtm 2f60e0a59e Use meaningful types for byte output functions 2020-02-10 03:36:51 +01:00
ISSOtm ffe9e92b48 Skip double-checking overflow in byte output 2020-02-10 03:36:51 +01:00
ISSOtm aa90a53f34 Move 1-byte overflow check to out_AbsByte 
This check is already performed in bulk by all functions calling it except
`out_AbsByte`, adding extra overhead to those.
 2020-02-10 03:36:51 +01:00
ISSOtm 598c923506 Use callback for PC's value 
This causes it to auto-update whenever the current section's attributes are
updated, simplifying the code and eliminating redundancy.
This should also overall reduce overhead (one extra function call on each
PC evaluation, but less bookkeeping for each byte output)
 2020-02-10 03:36:51 +01:00
ISSOtm 8c4b473d6f Add more checks to section creation in RGBASM 
Fixes rednex#471, but also backports a couple more checks from RGBLINK

ISSOtm 4e8b34f42e Improve error message when a symbol is not constant 2020-02-10 02:51:48 +01:00
ISSOtm 5014f55c48 Treat PC as a symbol as well 2020-02-10 02:51:48 +01:00
ISSOtm 1d78cd0f03 Axe the constexpr expression evaluator 
This avoids redundancy between them (and also having to port fixes and features)
The error messages have been preserved through a string reporting mechanism
 2020-02-10 02:51:48 +01:00
ISSOtm 52d62c6b21 Handle subtractions between labels 2020-02-10 02:47:50 +01:00
ISSOtm b4a73f33ce Avoid undefined behavior when shifting in RPN math 2020-02-10 02:47:50 +01:00
ISSOtm f9c25608e9 Ignore RPN strings when their value is known 2020-02-10 02:47:50 +01:00
ISSOtm 9fb9e63554 Reserve space for RPN expressions in a single call 
This should mean less overhead with some commands
 2020-02-10 02:47:12 +01:00
ISSOtm 9ce8a9f5f0 Add comments to RPN expr struct 2020-02-10 02:47:12 +01:00
ISSOtm cc59730c5b Cleanup the RPN evaluator somewhat 
Make the bool field an actual bool
Rename `iReloc` to a more exact `isKnown` (as was already pointed out by some
comments)
Make the value of `BANK(symbol)` consistent when the argument is invalid
 2020-02-10 02:47:12 +01:00
ISSOtm 0a04904b75 Refactor RPN binary expressions into a single func 
This mirrors what the constexpr evaluator is doing, and removes a lot of code shared
between all of them
 2020-02-10 02:47:12 +01:00
ISSOtm 9ed6e9af65 Make = a separate token from SET 
This does break backwards compat, but if anyone complains I'm gonna be mad
 2020-02-10 00:49:45 +01:00
ISSOtm c424a9bf5a Only output a single error with charmaps 2020-02-09 22:15:43 +01:00
ISSOtm 9d811e1267 Warn when truncating values in charmap 2020-02-09 22:13:16 +01:00
ISSOtm af6f62701c Remove ambiguous charmap syntax 
The syntax was `charmap "anything", "string"`; the second string was
already handled by `const`, but to the same effect... the ambiguous
declaration has been removed, leaving us at "only" two reduce/reduce
conflicts.
 2020-02-09 22:03:11 +01:00
ISSOtm 299574221e Truncate shift.out.bin 
Too large a size makes diff output (when tests fail) annoying
