There are two spots I could find in ifcvt.c: /* Convert "if (test) foo++" into "foo += (test != 0)", and similarly for "foo--". */ and /* Convert "if (test) x = 0;" to "x &= -(test == 0);" */ Would a patch such as the following be acceptable? http://article.gmane.org/gmane.comp.gcc.patches/151261 Sam -- Samuel Tardieu -- [EMAIL PROTECTED] -- http://www.rfc1149.net/
