From 8c3f943410ccfd79bb24eaa816dc8d57200d7a4c Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Tue, 2 Oct 2012 16:42:36 +0200 Subject: kbuild: Fix gcc -x syntax The correct syntax for gcc -x is "gcc -x assembler", not "gcc -xassembler". Even though the latter happens to work, the former is what is documented in the manual page and thus what gcc wrappers such as icecream do expect. This isn't a cosmetic change. The missing space prevents icecream from recognizing compilation tasks it can't handle, leading to silent kernel miscompilations. Besides me, credits go to Michael Matz and Dirk Mueller for investigating the miscompilation issue and tracking it down to this incorrect -x parameter syntax.
