Remove zone allocator.
This patch removes the GC zone allocator. It is not used and it
produces several regressions in the testsuite. Furthermore, it
complicates things for the plan to implement manual GC markers
(http://gcc.gnu.org/wiki/cxx-conversion/gc-alternatives#Do_GC_marking_manually).
Tested on x86_64 with standard checking, --enable-checking=gc and
--enable-checking=release.

If not see garbage collector. Similar results have been seen on a wider variety of tests (such as the compiler itself). - We could also use a zone allocator for these objects since they have - a very well defined lifetime. If someone wants to experiment with that - this is the place to try it. - PHI nodes have different sizes, so we can't have a single list of all the PHI nodes as it would be too expensive to walk down that list to find a PHI of a suitable size. |
