	Store the cache position data in jit_gencode struct.
	* jit/jit-rules.h, jit/jit-rules.c: (_jit_gen_check_space)
	(_jit_gen_alloc): add.
	* jit/jit-cache.h, jit/jit-cache.c (_jit_cache_get_function):
	rename from _jit_cache_get_method.

	* jit/jit-cache.h, jit/jit-cache.c (_jit_cache_end_method): add
	result argument that indicates if the code genration will need
	to be restarted.
	* jit/jit-cache.h, jit/jit-cache.c (jit_cache_mark_full): remove
	macro and replace it with direct jit_cache_posn access where
	appropriate.
	* jit/jit-cache.h, jit/jit-cache.c (jit_cache_get_posn): likewise.
	* jit/jit-cache.h, jit/jit-rules-interp.c (jit_cache_native): move
	macro to where it only used.
	* jit/jit-cache.h, jit/jit-cache.c: remove other unused stuff.

2012-01-22  Klaus Treichel  <ktreichel@web.de>

	* config/jit-opcodes.ops: Move declaration of obsolete opcodes to
	the separate include file jit-opcode-compat.h and include this new
	file instead.

	* include/jit/jit-opcode-compat.h: add new include file for
	obsolete opcodes.

	* include/jit/Makefile.am: add jit-opcode-compat.h to the include
	sources.

2012-01-21  Aleksey Demakov  <ademakov@gmail.com>

	* jit/jit-rules.h (struct jit_gencode): add offset_encoder field
	to encode bytecode offsets with jit_varints.

	* jit/jit-internal.h (struct _jit_function): move fields cookie,
	start, end here from jit_cache_method; add bytecode_offset field
	to encode bytecode offsets with jit_varints.

	* jit/jit-compile.c (mark_offset, _jit_function_get_bytecode): add
	functions that use jit_varints for bytecode offset compression.

	* jit/jit-cache.h, jit/jit-cache.c (_jit_cache_get_method):
	remove cookie argument.

	* jit/jit-cache.h, jit/jit-cache.c (_jit_cache_mark_bytecode)
	(_jit_cache_set_cookie, _jit_cache_get_start_method)
	(_jit_cache_get_end_method, _jit_cache_get_native)
	(_jit_cache_get_bytecode, _jit_cache_get_size): remove functions,
	get rid of bytecode offset compression and method region machinary.

	* jit/jit-dump.c, jit/jit-function.c, jit/jit-rules-interp.c
	* jit/jit-except.c, jit/jit-unwind.c: adjust where appropriate for
	cache API change.

	* jit/Makefile.am:
	* jit/jit-varint.h, jit/jit-varint.c: add new files for varaible
	length int encoding with algorithm similar but not identical to one
	currently used in jit-cache.c.  The new algorithm in certain cases
	better compresses unsigned ints.
