Totally broken tag operator

[Y-Less]

Issue description:

Somehow having a custom assignment operator it is seen as unused and prevents all code generation. The code below gives:

(17) : warning 203: symbol is never used: "_:operator=(Tag:)"

And the assembly output is:

CODE 0	; 0
;program exit point
	halt 0


STKSIZE 1000

Literally nothing...

Minimal complete verifiable example (MCVE):

#pragma option -a

native printf(const str[], ...);

operator=(Tag:x)
{
	return _:x:
}

main()
{
	new a = Tag:5;
	printf("%d", a);
}

Workspace Information:

• Compiler version:
• Command line arguments provided (or sampctl version):
• Operating System:

This issue is not specific to the assignment operator; it can be reproduced with any operator.

Code which appears after the operator declaration is ignored by the compiler. The code which comes above the operator declaration appears in the assembly.

#pragma option -a

native printf(const str[], ...);

operator=(Tag:x)
{
	return _:x:
}

Hi, you can add junk code here and the compiler stays happy.


main () {
	f();
		new a = Tag:5;
	printf("%d", a);
}

but looking at some debug printfs, it appears like the compiler actually processes these

gives just

warning 203: symbol is never used: "_:operator=(Tag:)"

[YashasSamaga]

Removing return _:x somehow fixes it.

[YashasSamaga]

Oh @Y-Less, you had a typo in your code. You have return _:x: instead of return _:x; (colon instead of semicolon). This somehow caused the compiler to go nuts.

The compiler should've triggered an error about the :.

[Y-Less]

Well that's insane that that typo caused that (at least it wasn't a Greek question mark), but that still seems like a bug, even if a slightly different one.
