From e49d021e574c3ee8e443bcc84d1fb7dfb4c87c42 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Fri, 7 Dec 2012 15:39:13 +0000 Subject: [PATCH] configure: Default to 'cc', not 'gcc' Default to 'cc' as our compiler, rather than 'gcc'. We used to have to insist on gcc when we still kept the CPU env in a fixed global register, but this is no longer necessary and we will now compile OK on clang as well as gcc. Using 'cc' should generally result in us using the most standard and maintained system compiler for the platform. (For instance on newer MacOS X 'gcc' exists but is an elderly compiler provided mostly for legacy reasons, and 'cc' (which is clang) is definitely the better choice.) On Linux there will generally be no user-visible change since cc will be gcc. This changeover necessitates a slight reworking of how we set the 'cc' variable, because GNU cross toolchains generally provide a '${cross_prefix}gcc' but not a '${cross_prefix}cc'.
