h8300-hms-gcc fails to build

[Kazu Hirata <kazu at hxi dot com>]

Hi,

The latest version of h8300-hms-gcc (right out of CVS) fails to build
on i686 with RedHat Linux 6.2.

The build process stops with the following message.

Command exited with non-zero status 2

The core of the problem seems to be compiling the following piece of code.

extern void start() __asm__("start");

void start() {}

With the same options as libgcc1-test.c, this gets compiled to:

;	GCC For the Hitachi H8/300
;	By Hitachi America Ltd and Cygnus Support
;	release F-1
; -O2


	.file	"ttt.c"
	.section .text
	.align 1
	.def	_*start
	.val	start
	.scl	2
	.type	041
	.endef
	.global start
start:
	.def	.bf
	.val	.
	.scl	101
	.line	3
	.endef
	push	r6
	mov.w	r7,r6
	.def	.ef
	.val	.
	.scl	101
	.line	1
	.endef
	pop	r6
	rts
	.def	_*start
	.val	.
	.scl	-1
	.endef
	.end

I don't know where '*' in _*start coms from.

Thanks,
