- Subject: [PATCH] boehm-gc: Fix mips64-linux n64 configuration.
I have been working on getting libgcj runninng on mips64-linux. The
boehm-gc configuration for the n64 ABI was incorrect causing SIGBUS in
GC initialization. This patch duplicates some of the logic used in the
Irix5 case.
With the patch applied I can successfully run a large majority of the
libgcj testsuite cases on mips64-linux with -mabi=64.
Hans, this patch should probably also be committed to the upstream sources.
Before committing I will test x86_64-pc-linux-gnu.
OK to commit if testing shows no regressions?
