Description Chris Lattner 2006-12-18 23:55:43 PST 
-x86-asm-syntax=intel yields:

$BB1_2451:	;bb740
	mov EAX, <unknown operand type>
	mov ECX, DWORD PTR [ESP + 1372]
	jmp DWORD PTR [EAX + 4*ECX]

AT&T yields:

LBB1_2451:	#bb740
	movl $LJTI1_3, %eax
	movl 1372(%esp), %ecx
	jmpl *(%eax,%ecx,4)

Chris, could you please attach failed bytecode. All examples I've tried to
construct by myself lead to assertion (for intel syntax). Need to investigate
more, but it's somehow different task :)

Quick'n'-dirty patch

I don't have bytecode to play with (see prev. comment), so this is just some
possible way to fix. Let me know thhe results.

The example in bug 1061 now demonstrates this issue.
