- Subject: [PATCH] Names of heap vars in alias analyzer
Hi,
This is a small fix for the alias analyzer, to use alias_get_name() to
set the name field when creating the varinfo for heap variables. This
lets constraints be printed with full variable names in the dump file.
(e.g. HEAP.12 instead of just 'HEAP')
C.L.

* tree-ssa-structalias.c (make_constraint_from_heapvar): Use
alias_get_name() to set varinfo name field.
