[committed] Tighten some rtx-based variable and return types
- From: Richard Sandiford <rdsandiford at googlemail dot com>
- To: gcc-patches at gcc dot gnu dot org
- Date: Sat, 06 Jun 2015 14:15:35 +0100
- Subject: [committed] Tighten some rtx-based variable and return types
- Authentication-results: sourceware.org; auth=none
These are the main rtx-related changes found by the -Wupcast-* warnings
that I posted last week.
Bootstrapped & regression-tested on x86_64-linux-gnu. Also tested on
config-list.mk, checking that all build failures were unrelated.
Applied as obvious.
Thanks,
Richard
