[PATCH][4/n] Allow anonymous SSA names
- From: Richard Guenther <rguenther at suse dot de>
- To: gcc-patches at gcc dot gnu dot org
- Date: Wed, 8 Aug 2012 15:52:51 +0200 (CEST)
- Subject: [PATCH][4/n] Allow anonymous SSA names
This splits out more cleanups from the main patch to make that smaller.
The only bigger part of the patch is making tree-stdarg track
escapes/varargs for SSA names more precise by not globbing on
SSA_NAME_VAR but instead using the bits [0..num_ssa_names-1] for
SSA names and [num_ssa_names,max_decl_uid + num_ssa_names] for decls
in its bitmap. Eventually this pass will get rewritten by Micha anyway
who has pending patches to make va_arg survive until after inlining.
Bootstrapped on x86_64-unknown-linux-gnu, testing in progress.
Richard.
