RE: [boehms-gc, libjava?] Update Boehm's GC to 6.8


The approximately equivalent code in the atomic_ops package, and hence
in 7.0, reads:

AO_INLINE AO_TS_VAL_t
AO_test_and_set_full(volatile AO_TS_t *addr) {
  int oldval;
  /* SWP on ARM is very similar to XCHG on x86.                 */
  /* The first operand is the result, the second the value      */
  /* to be stored.  Both registers must be different from addr. */
  /* Make the address operand an early clobber output so it     */
  /* doesn't overlap with the other operands.  The early clobber*/
  /* on oldval is neccessary to prevent the compiler allocating */
  /* them to the same register if they are both unused.         */
  __asm__ __volatile__("swp %0, %2, [%3]"
                        : "=&r"(oldval), "=&r"(addr)
                        : "r"(1), "1"(addr)
                        : "memory");
  return oldval;
} 

This looks far more convincing to me.  I think the __asm__ line could be
taken verbatim, though it would be great if someone could test.

The underlying problem is that this instruction has weird register
constraints, as documented here.  I'm not sure that this particular
encoding into gcc asm notation is in any sense optimal.

> +INSTALLATION:
> +Under UN*X, Linux:
> +Alternative 1 (the old way): type "make test" in this directory.
> +	Link against gc.a.
> +
> +Alternative 2 (the new way): type
> +	"./configure --prefix=<dir>; make; make check; make install".
> +	Link against <dir>/lib/libgc.a or <dir>/lib/libgc.so.
> +	See README.autoconf for details
> +
> +Under OS/2 or Windows 95, 98, Me, NT, or 2000:
> +copy the appropriate makefile to MAKEFILE, read it, and type 
> "nmake test".
> +(Under Windows, this assumes you have Microsoft command-line tools
> +installed, and have DOS configured with enough environment 
> space to run them.)
> +Read the machine specific README in the doc directory if one exists.
> +The only way to develop code with the collector for Windows 3.1 is
> +to develop under Windows NT or 95+, and then to use win32S.
> +
> +If you need thread support, you will need to either follow 
> the special
> +platform-dependent instructions (win32), or add a suitable define
> +option as described in Makefile.
> +
> +If you wish to use the cord (structured string) library, type
> +"make cords". (This requires an ANSI C compiler.  You may need
> +to redefine CC in the Makefile. The CORD_printf implementation in
> +cordprnt.c is known to be less than perfectly portable.  The rest
> +of the package should still work.)
> +
> +If you wish to use the collector from C++, type
> +"make c++".  These add further files to gc.a and to the include
> +subdirectory.  See cord/cord.h and include/gc_cpp.h.
> +
> +TYPICAL USE:
> +Include "gc.h" from the include subdirectory.  Link against the
> +appropriate library ("gc.a" under UN*X).  Replace calls to malloc
> +by calls to GC_MALLOC, and calls to realloc by calls to GC_REALLOC.
> +If the object is known to never contain pointers, use 
> GC_MALLOC_ATOMIC
> +instead of GC_MALLOC.
> +
> +Define GC_DEBUG before including gc.h for additional checking.
> +
> +More documentation on the collector interface can be found at
> +http://www.hpl.hp.com/personal/Hans_Boehm/gc/gcinterface.html,
> +in doc/README, and in include/gc.h .
> +
> +WARNINGS:
> +
> +Do not store the only pointer to an object in memory allocated
> +with system malloc, since the collector usually does not scan
> +memory allocated in this way.
> +
> +Use with threads may be supported on your system, but requires the
> +collector to be built with thread support.  See Makefile.  
> The collector
> +does not guarantee to scan thread-local storage (e.g. of the kind
> +accessed with pthread_getspecific()).  The collector does scan
> +thread stacks though, so generally the best solution is to 
> ensure that
> +any pointers stored in thread-local storage are also stored on the
> +thread's stack for the duration of their lifetime.
