Done. Bootstrapped on x86, amd64, ppc, alpha and ia64. Not all the
testsuites have finished running, but the ones that are done show no new
failures, with the exception of x86 and ia64. On x86 we are failing
gcc.dg/20020531-1.c and gcc.dg/tls/opt-6.c. I'll be looking at those
next.
On ia64 I'm getting failures on tests that use libunwind: "error while
loading shared libraries: libunwind-ia64.so.1: cannot open shared object
file: No such file or directory". This is not related to the patch. I
must have something misconfigured somewhere.
This patch is the last major piece needed for the base SSA framework.
Thank you Andrew! Now on to performance tweaking.
Diego.
