ba13ba32a1 Fix some commonly made spelling errors in comments. 2022-07-21 03:18:13 +02:00

e35f4fb48f Invalid flagged errors if token is missing 
A missing factor in an expression causes an expected but missing token
to be skipped, leading to invalid flagged errors in the following line:

l = 3 +
lda     #$00

An error should be output for line 1, but not for line 2. Actually, both
are flagged as errors:

test.s(1): Error: Syntax error
test.s(2): Error: Unexpected trailing garbage characters

This patch (as proposed in issue #1634 by kugelfuhr) fixes this.

800568dd58 Added code that avoids infinite loops that were caused by circular references 
(a symbol that was defined by referring to itself directly or indirectly).  Patch by kugelfuhr.

ac2ecb0b2c 65816 now generate EXPR_NEARADDR instead of EXPR_WORD0 for default assumed address mode, which will be validated by the linker's range check rather than blindly truncated. Assuming the assembler correctly validated this, the linker is allowed to truncate. 2019-05-11 12:32:44 +02:00

a6b04f6e97 Changed most "backticks" (grave accents) into apostrophes. 
Quotations that are embraced by tick marks now look better, in most fonts.

67cd0c2197 Added .asize and .isize pseudo variables 
These pseudo variables will return the size of the accumulator/index
in bits.

For the 65816 instruction set .ASIZE/.ISIZE will return either 8 or 16,
depending on the current size of the operand in immediate addressing
mode.

For all other CPU instruction sets, .ASIZE/.ISIZE will always return 8.

For example:

	; Reverse Subtract with Accumulator
	; A = memory - A
	.macro rsb param
		.if .asize = 8
			eor	#$ff
		.else
			eor	#$ffff
		.endif
		sec
		adc	param
	.endmacro

43ea0e3df9 Move evaluation of the argument for .BANK into the linker. It is otherwise too
