From 3234282f33b29d349bcada40204fc7c8fda7fe72 Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Tue, 19 Oct 2010 14:52:26 +0100 Subject: x86, asm: Fix CFI macro invocations to deal with shortcomings in gas gas prior to (perhaps) 2.16.90 has problems with passing non- parenthesized expressions containing spaces to macros. Spaces, however, get inserted by cpp between any macro expanding to a number and a subsequent + or -. For the +, current x86 gas then removes the space again (future gas may not do so), but for the - the space gets retained and is then considered a separator between macro arguments. Fix the respective definitions for both the - and + cases, so that they neither contain spaces nor make cpp insert any (the latter by adding seemingly redundant parentheses).
