Commit Message

David Malcolm Sept. 5, 2014, 1:15 a.m. UTC 
The attached patch strengthens both params of fixup_args_size_notes from
rtx to rtx_insn * (eliminating a checked cast), and thus falls under the
pre-approval granted by Jeff here:
  https://gcc.gnu.org/ml/gcc-patches/2014-08/msg01310.html

Bootstrapped on x86_64-unknown-linux-gnu (Fedora 20), and has been
rebuilt as part of a config-list.mk build for all working configurations
(albeit with other patches for the latter case).

Committed to trunk as r214930.
