From 046957830e176ad16fdef39bc7f1cd44d8fbc3b7 Mon Sep 17 00:00:00 2001 From: Jim Meyering Date: Wed, 20 Apr 2011 18:19:03 +0000 Subject: remove useless if-before-free tests Change "if (E) free (E);" to "free (E);" everywhere except in the libgo/, intl/, zlib/ and classpath/ directories. Also transform equivalent variants like "if (E != NULL) free (E);" and allow an extra cast on the argument to free. Otherwise, the tested and freed "E" expressions must be identical, modulo white space.
