There is a compelling need for it in Fedora 9, but only on sparc. I
didn't tag or request a build for any other architectures. This should
not affect the TCK certification.
Apologies for the confusion. I noticed that rawhide was significantly
different from Fedora 9, and I will rework these patches to that branch
as they are applicable. I didn't want these patches to get lost, so I
committed them.
As a breakdown, here is what these patches do (they should all be
applicable upstream):
java-1.6.0-openjdk-sparc-ptracefix.patch:
Rather than source asm-sparc/ptrace.h (on pure 32bit sparc userland,
asm-sparc/ doesn't exist, only asm/), I simply include the pt_regs
struct that sparc and sparc64 use. Only affects sparc and sparc64.
java-1.6.0-openjdk-sparc-trapsfix.patch:
On pure 32bit sparc userland (kernel-headers.sparc), asm-sparc/
doesn't exist, but asm/ does. On pure 64bit sparc64 userland
(kernel-headers.sparc64), asm-sparc and asm-sparc64 exist. Still with
me? :) We need the traps define from asm-sparc on both sparc and
sparc64 compiles (there is no traps.h in asm-sparc64), so this patch
fixes it such that we get the right header included in both scenarios.
Only affects sparc and sparc64.
java-1.6.0-openjdk-sparc64-INSTALL_ARCH_DIR.patch:
Sun uses the term "sparcv9" to describe a 64bit sparc environment.
This is ok on Solaris, but on Linux, we use "sparc64" to describe a
64bit sparc environment. For 99% of the uses inside openJDK this is
fine, but when bootstrapping off gcj, it makes symlinks to a
non-existent jvm dir called "sparcv9". This patch adds another
configure variable called "JRE_ARCH_DIR" which is the same as
"INSTALL_ARCH_DIR" for all other arches except sparcv9 (where
JRE_ARCH_DIR is set to sparc64). This patch might need to be
conditionalized for bootstrapping only, not sure yet as I haven't
done a non-bootstrap build for sparc64 yet. No behavior change for
non-sparc/sparc64 architectures.
java-1.6.0-openjdk-sparc64-linux.patch:
Adds a sparcv9.make makefile for 64bit (sparc64). Fixes two bugs
inside c1_LIRGenerator_sparc.cpp, one where int conversion wasn't
correct on sparc64 and one where it called non-existant functions on
sparc64. store_mem_reg and load_mem_reg might be defined for Solaris,
but I couldn't find them defined in the source tree at all, so I \
assumed they were not-yet-implemented. Fixed
hotspot/build/linux/makefiles/defs.make to more cleanly handle
sparc/sparc64 cases. Only affects sparc and sparc64.
With these four patches applied, and the minor spec file changes
(defining archbuild and archinstall for sparc/sparc64), I was able to
bootstrap basic functioning sparc and sparc64 openJDK for Linux. I used
that bootstrapped openJDK to build a clean sparc RPM and I've just
kicked off the sparc64 build. We really need these to finish building
the rest of the java stack for Fedora 9 on SPARC.
