BUG (egcs-2.90.27): -fPIC and _syscallX ()

[Martin Baulig <norwegen at home-of-linux dot org>]

-----BEGIN PGP SIGNED MESSAGE-----

I have

        egcs-2.90.27 980315 (egcs-1.0.2 release)
        Linux voyager 2.0.32 #32 Sat Jun 13 19:52:48 CEST 1998 i686
        glibc-2.0.7-5

The following error occurs every time you try to compile a
function that uses _syscallX () with -fPIC; here's some sample
program than can reproduce the bug:

	#include <linux/unistd.h>

	#include <syscall.h>

	static inline _syscall1 (void, exit, int, code);

	int
	main (void)
	{
		exit (0);
	}

Compile this with

	$ gcc -o test -fPIC test.c

and you will get

	norwegen:~/bug - 2654 > gcc -o test -fPIC test.c
	test.c:5: warning: `exit' was declared `extern' and later
	`static'
	test.c: In function `exit':
	test.c:5: warning: `return' with a value, in function returning
	void
	test.c:12: fixed or forbidden register was spilled.
	This may be due to a compiler bug or to impossible asm
	statements or clauses.

The problem does not occur when you compile without '-fPIC'.
