Author: Thomas Preud'homme <robotux@celest.fr> Date: Tue Dec 31 23:51:20 2013 +0800 Move logic for if (int value) to tccgen.c Move the logic to do a test of an integer value (ex if (0)) out of arch-specific code to tccgen.c to avoid code duplication. This also fixes test of long long value which was only testing the bottom half of such values on 32 bits architectures. I don't understand why if () in gtst(i) was removed. This patch allows to compile a linux kernel v.2.4.26 W/o this patch a tcc simply crashes.
