PR164: Get rid of mysterious 10 trailing bytes in literal strings.
This actually caused page faults in memcpy, when they happened to straddle a
page boundary and the adjacent page was not mapped.

PR163: descriptor_params_from_paramtypes is protected by a mutex now (per descriptor pool).
By careful use of StoreStore and ReadRead memory barriers, we could also use a
kind of double-checked locking on the params field, but the potential
performance gain is definitely not worth the trouble (and risk).

Removed return value from descriptor_params_from_paramtypes.
It always returned true. Propagated change along all call paths.

* src/native/vm/reflection.cpp: Propagated conditional removal.
* src/vm/descriptor.cpp: Removed return value.
* src/vm/descriptor.hpp: Likewise.

abc_optimization: Fixed the most obvious typos;
I refrained from fixing most of the grammar errors though

Makes --disable-gc work again

* src/threads/thread.cpp : attach_custom_finalizer(..) depends on an enabled boehm gc

Documentation for the ABC Analysis

Regression test driver now can read different expected output files
depending on classlibrary used (classpath vs. openjdk).

Provided expected results for openjdk builds (to be discussed).

Small fix in extest.java preventing an NegativeArrayIndexException to be thrown.

* src/native/jni.cpp: [OPENJDK] Fix FindClass called from JNI_OnLoad.
Triggered by lwjgl.

* src/native/jni.cpp: [OPENJDK] Implemented jni_GetDirectBufferCapacity.
* src/vm/javaobjects.hpp: Added java_nio_Buffer::get_capacity.

* src/vm/jit/arm/emit.c (emit_verbosecall_enter): Remove broken support for
float argument passing in registers

The removed code was not prepared for handling register numbers constructed by
PACK_REGS and would produce illegal instructions.

* src/vm/jit/arm/codegen.c: Remove hack for return value in float registers.

This would only be relevant for -mfloat-abi=hard (armhf). At the moment,
support for armhf is rather pointless and can never have worked because all
arguments are passed in integer registers unconditionally. This applies to both
the internal and the system ABI.

* src/vm/jit/arm/codegen.c: Fixed use of uninitialized variable.

* src/vm/jit/arm/codegen.c: removed unused ICMD_GETSTATIC branch

* src/vm/jit/arm/asmpart.S: Designate function labels as such; required for
thumb interworking.

Fixed some testcases

* tests/regression/jasmin/* : jasmin changed and couldn't handle " anymore in declarations

PR149: Used wrong class loader.
* src/vm/globals.cpp: Added two new classes: sun/reflect/MethodAccessorImpl and
sun/reflect/ConstructorAccessorImpl.
* src/vm/globals.hpp: Likewise.
* src/vm/jit/stacktrace.cpp: Skip stack frames belonging to these classes when
looking for a class loader.
* src/vm/linker.cpp: Link these classes.
* src/vm/loader.cpp: Load these classes.

* src/vm/javaobjects.cpp (java_lang_reflect_Method::invoke): [OPENJDK] stack
index of caller was off by one, causing many apt (Annotation Processing Tool)
failures.

PR159: Exception handler blocks / register mixup
* src/vm/jit/codegen-common.cpp: Fix register allocation at exception handler
block boundaries.
The concept of a block type is flawed because an exception handler block can
also be reached via normal control flow. I guess subroutine blocks are safe
because they expect a different type on the stack (returnAddress), and any
attempt at reaching them normally would not get past the verifier, although I
don't know how this is handled in CACAO.

The conditional branches should be handled as well, but as there is a lot of
platform-specific code involved as well as lots of register clobbering
potential, I'll leave it at that for now.

* src/threads/thread.cpp: Set thread to RUNNABLE during Thread.start.
* src/threads/posix/thread-posix.cpp: Removed state-setting function call that
would be done by the thread itself, creating a nasty race.

merged threadlist & threadobject improvements

* src/threads/threadlist.cpp: Fixed strategy for giving out thread indexes.

* src/threads/thread-classpath.cpp, src/threads/thread-classpath.hpp,

(clear_heap_reference): Added.
* src/vm/javaobjects.cpp, src/vm/javaobjects.hpp [OpenJDK]:

* src/threads/thread.hpp: Likewise.
* src/threads/posix/thread-posix.hpp: Added flag is_in_active_list.
* src/threads/threadlist.cpp, src/threads/threadlist.hpp: Take thread list lock
for all thread list operations.
(deactivate_thread): Added.
* src/threads/thread-classpath.cpp: Adapted to lock change.

* src/threads/thread.cpp: thread_new no longer adds to active list.
* src/threads/threadlist.hpp (add_to_active_thread_list): Take the thread list
lock when changing the thread list.

* src/threads/posix/thread-posix.cpp, src/vm/jit/stacktrace.cpp: Sanitize
the usage of condition variables.

* src/threads/posix/thread-posix.cpp: Take care not to signal threads after
they have stopped existing.

PR157: ARM memory barrier
* src/vm/jit/arm/md-atomic.hpp: Add memory barriers, use gcc intrinsic for CAS.
Obsoletes icedtea patches arm-arch-defines.patch and arm-memory-barrier.patch.
Thanks Xerxes Ranby.

* src/vm/vm.cpp: Ignore all unknown options, but report them.
Obsoletes icedtea6 patch ignore-unknown-options.patch.
Thanks Xerxes Ranby.

* src/mm/boehm-gc/Makefile.am, src/mm/boehm-gc/libatomic_ops/Makefile.am:
Repair make distcheck.

* tests/regression/bugzilla/Makefile.am: Added missing files to EXTRA_DIST.

Fixes build for newer gcc (at least 4.4), breaks older gcc. We don't care.

This only changes the build process slightly, the code is left as-is.

boehm-gc: revert all CACAO-specific modifications; this is now an exact copy of the bdwgc CVS repository as of 2009/09/09 22:31:20

* src/vm/linker.cpp, src/vm/linker.hpp: Added linker_create_string_later,

* src/threads/thread.cpp (thread_set_state_*): Don't take the ThreadList
lock, most of the time.

We need the lock only when changing the state to terminated. This prevents
other threads from using a stale threadobject * (they have to take the lock,
of course). This changeset removes a nasty deadlock:

Thread 1 locks ThreadList::_mutex -> waitmutex (via thread_handle_interrupt
-> threads_thread_interrupt)
Thread 2 locks waitmutex -> ThreadList::_mutex (via
threads_wait_with_timeout -> thread_set_state_runnable)

The deadlock is provoked by running tests/threads/waitAndInterrupt.java (in
the CACAO source tree). The bug was introduced in changeset a62d7ef60606 (PR
120).
