From: Thomas Petazzoni Date: Wed, 28 Jul 2010 10:02:30 +0000 (+0200) Subject: gcc: remove option on SJLJ exceptions X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6d4a992e2b817cc14276c68e0321edaf66450cf3;p=buildroot.git gcc: remove option on SJLJ exceptions This is a very advanced option, and it seems, according to http://choices.cs.uiuc.edu/exceptions.pdf that SJLJ exceptions aren't really interesting. Users really interested by this can always use the BR2_EXTRA_GCC_CONFIG_OPTIONS is they want.
