Cleanup fipa-pta constraint dumping
2015-10-30 Tom de Vries <tom@codesourcery.com>
* tree-ssa-structalias.c (ipa_pta_execute): Declare variable from as
unsigned, and initialize, and use initial value instead of hardcoded
constant. Add generic constraints dumping section. Don't dump global
initializers constraints dumping section if empty. Don't update
variable from if unused.
