5ba4d043e5 merlin linker truncates opcodes to 3-characters. 
This allows for things like `TYPe` and `LINk`

QLink IIgs - inappropriate interseg OMF records
 2020-05-26 21:38:18 -07:00
Kelvin Sherlock
ca29613395 external, shifted references were always generating an interseg OMF relocation record even when in the same OMF segment (in which case they would reference segment 0 which is wrong). 2020-05-26 22:48:47 -04:00

b4bf2c1611 fix to macro operand parsing for quoted strings 
macro operand parsing code was a little too clever and had problems if both ' and " delimiters were present.

new code uses separate loops for handing delimited strings and raw strings, to keep things simpler and more correct.

```
xx	mac
	asc ]1
	eom

	xx '"hello"'
	xx "'hello'"
	xx 'hello'
	xx "hello"
	xx 'abc',00
	xx ff

 ```

89b7308c15 Update labels/symbol size from 15 to 31. 
Magic number offsets are also replaced with named constants.

Merlin 16+ increased the label size from 12 to 26 at some point and the 15-char limit causes duplicate label errors on some Merlin source code.

da1c2e8222 adds back error checking which was previously disabled due to the illegal relative value bug.

 2020-01-13 22:13:16 -05:00
Kelvin Sherlock
861bb44d32 only add .S extension as necessary 
modifies the asm command line, linker command line, and linker ASM/PUT/IF opcodes to only append a .S suffix if it's not already present.

this is more consistent with Merlin 16+ and less surprising for people who use the command-line asm or link commands.

7336daffbf fix y2k overflow. 
_ReadTimeHex returns the year as an offset from 1900, so 2020 is 120, which overflows ('0' + 12 is ascii '<')

subtract 100, repeatedly, until it fits in 2 digits.  Should last into 2100.

(IIgs qasm) Add system 6.0 / System 6.0.1 macros 
I regenerated the pre-compiled toolmacs file based on GSBug's toolcall list (plus Marinetti toolcalls).

This includes new tools from system 6.0/6.01 and a a few name updates. The _DU is gone I don't know what that is offhand and I dare say nobody used it since it doesn't exist.
