The development-only VM option -XX:+VerifyOops is useful for more quickly
isolating oop-map and unhandleized oop related bugs. Currently on x86 this
option does not work, at least with the client compiler in -Xcomp mode, because
the verify_oop subroutine does not preserve condition codes as it does on other
platforms (at least SPARC). It would be helpful to have the fix for this problem
checked into the 1.5.0 tree so that it is available in case we need to build
this workspace with debugging options enabled for problems encountered in the
field.
