To: gcc-patches
This patch introduces const_basic_block and const_edge typedefs, and I
constified a bunch of places. I also managed to zap one of the
remaining -Wcast-qual warnings:
> cfgloop.c:800: warning: cast discards qualifiers from pointer target type
Bootstrapped on sparc-sun-solaris2.10, no regresions. Installed.
