b2d523acde rgbasm: Evaluate BANK() arguments to verify they exist. 
Symbols are created when using a label in the wild, even if they aren't defined. Solely using a symbol as an argument to BANK() skips this, so the symbol is never created.

This evaluates the argument instead of trying to find a symbol. This way, symbols that don't exist are created when passed into BANK().

1f9fd0f060 This fixes an error with using long label names in macros. If the label name you're using is longer than the string length of the literal macro text, a syntax error would occur. This fix makes sure it at least allocates enough bytes for the largest allowed label name. 2013-12-22 20:56:31 -05:00

de269987f7 Add "jp hl" as a valid instruction. 
"jp [hl]" has been around for decades even though it makes no sense.

Prevent lexer from reading beyond the end of the buffer

2dfd937d7f Prevent lexer from reading beyond the end of the buffer 
On Linux, valgrind complains about the overflow like this:

  Pass 1...
  ==20054== Invalid read of size 1
  ==20054==    at 0x406CDA: yylex (lexer.c:396)
  ==20054==    by 0x40207C: yyparse (asmy.c:2921)
  ==20054==    by 0x4086AF: main (main.c:351)
  ==20054==  Address 0x503a102 is 0 bytes after a block of size 23,538 alloc'd
  ==20054==    at 0x402994D: malloc (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so)
  ==20054==    by 0x406411: yy_create_buffer (lexer.c:147)
  ==20054==    by 0x404FE3: fstk_RunInclude (fstack.c:243)
  ==20054==    by 0x4025F5: yyparse (asmy.y:744)
  ==20054==    by 0x4086AF: main (main.c:351)
  ==20054==

This is a bit of a crude fix which simply exits the hashing loop when
we reach the end of the string. We should probably do some kind of
length calculation on the buffer instead.
