From 1aafd9091226a02b481298315f959f777294684e Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Wed, 25 Jul 2007 11:19:14 +0800 Subject: Blackfin arch: revise anomaly handling by basing things on the compiler not the kconfig defines revise anomaly handling by basing things on the compiler not the kconfig defines, so the header is stable and usable outside of the kernel. This also allows us to move some code from preprocessing to compiling (gcc culls dead code) which should help with code quality (readability, catch minor bugs, etc...).
