[PATCH] alias_invariant

[Devang Patel]

alias_invariant is GTY'ed so use ggc_realloc() instead of xrealloc().

2004-05-21  Devang Patel  <dpatel@apple.com>

         * alias.c (init_alias_analysis): Use ggc_realloc instead of
         xrealloc.
         (end_alias_analysis): Remove call to free().

Bootstrapped on powerpc-darwin. DejaGNU test run is in progress.
OK for mainline?
Thank you,
