From: Richard Earnshaw <rearnsha@arm.com> To: joel@OARcorp.com Cc: gcc-gnats@gcc.gnu.org, Richard.Earnshaw@arm.com Subject: Re: bootstrap/3147: arm-elf and arm-rtems unbuildable on 3.0 branch Date: Wed, 13 Jun 2001 12:35:42 +0100 This is a multipart MIME message. --==_Exmh_5568127680 Content-Type: text/plain; charset=us-ascii The problem is that some of the ARM files are forcibly defining __arm__ in CPP_PREDEFINES. This is wrong, since it causes longlong.h to define multiplication routines that are invalid for THUMB code.
