the compiler keeps returning these errors wheni try to compile my functions.s
file with my main c file
functions.s:

#include "r5900_regs.h"
        
.set noreorder

.text

	.global notarealfnc
	.ent	notarealfnc
notarealfnc&#58;
	lw	v0,	0x00&#40;t0&#41;
	addiu	v0, v0	4
	sw	v0, 	_addr
	jr	ra
	nop
	.end notarealfnc

ive defined my function in the c source as "extern void notarealfnc(void);" but the compiler throws out these errors, the only command it likes is a nop:

Code: Select all

	$ make
	ee-as -G0  functions.s -o functions.o
	functions.s&#58; Assembler messages&#58;
	functions.s&#58;0&#58; Warning&#58; end of file not at end of a line; newline inserted
	functions.s&#58;10&#58; Error&#58; illegal operands `lw v0,0x00&#40;t0&#41;'
	functions.s&#58;11&#58; Error&#58; illegal operands `addiu v0,v0 4'
	functions.s&#58;12&#58; Error&#58; illegal operands `sw v0,_addr'
	functions.s&#58;13&#58; Error&#58; illegal operands `jr ra'
	make&#58; *** &#91;functions.o&#93; Error 1

thnx in advance

Unless I'm forgetting something, gas (ee-as) can't use "#include", since it doesn't invoke the CPP (C Preprocessor), ".include" does work though.

You can of course use ee-gcc to compile a .S or .s file though, if you want to use CPP directives. (hint: r5900_regs.h probably requires you do this)

Hope this helps.

...and if that doesn't work (I'm not saying that it shouldn't)
you could try to put a "$" before the register names (i.e. "addiu $t0,$t0,1"), thats how I solved the problem ;)

Use gcc to preprocess the assembly, like so:

gcc -c foo.S

Both .S and .s are assembler. By convention, .S is assembly source that
needs to be preprocessed. Otherwise, gcc doesn't care.

http://sourceware.org/ml/crossgcc/1997/msg00002.html

There's also an include file in ps2sdk somewhere that maps the register numbers to register names.
