From 4afb7fb761ee49595f25de66093bc021cbdfae16 Mon Sep 17 00:00:00 2001 From: Carl-Daniel Hailfinger Date: Fri, 4 Apr 2008 15:02:45 +0000 Subject: Add a workaround for a bug in some binutils version which strictly interpret whitespace as macro argument delimiter. Since the code is preprocessed by gcc and the tokenizer may insert whitespace, that can fail. http://sourceware.org/bugzilla/show_bug.cgi?id=669 The same change was committed in r3044 to the AMD CAR code.
