Yippee! Looks like I'm back in business on 10.6. -- John
With the current bsd-port plus unrelated MLVM patches I got a clean
Snow Leopard build. It passed the MLVM regression tests.
I had to use GCC 4.0 as Michael suggested.
The 4.2 compiler is offering some porting resistance. I put a patch
into MLVM which copes with the new "printf" warnings it generates:
http://hg.openjdk.java.net/mlvm/mlvm/hotspot/raw-file/f9a6cda5b465/snowleopard.patch
This patch is a bunch of lint-type fixes, and works fine on GCC 4.0.
(Haven't tested on Solaris, etc, but s.b. OK.) It's probably not
worth the effort of pushing this patch upstream until we have a
working GCC 4.2 build.
The current problem with GCC 4.2 is that when I build on x86_32, the
JVM crashes in at least two places: Under -Xint mode, the JVMG mode
throws an assert on exit, and otherwise it throws asserts or crashes
in compiler-related code. The 64-bit version of the JVM appears to
work, but I haven't exercised it much.
Since I'm chasing other problems, I'm going to leave GCC 4.2 alone for
now. If anyone wants to pick up this issue, help yourself to
snowleopard.patch above.
