------- Comment #2 from aph at gcc dot gnu dot org 2006-03-08 14:35 -------
I've started some experimental work on this at
svn+ssh://gcc.gnu.org/svn/gcc/branches/gcj/gcj-abi-experimental-branch.
Initial improvements in grabage collection time are encouraging, but there are
some problems with poor code quality. (In particular, accesses to items in the
constant pool are now doubly-indirect: class$->constants[n].) Before merging
this work to trunk I intend to do some benchmarking and and fix any performance
regressions I find.
