1999-01-19  Markku Rossi  <[e-mail]>

	* jsint.h (struct js_vm_st): Implemented file descriptor limit.
	Now you can specify the maximum amount of file descriptors the
	interpreter can allocate.  Thanks to Indrek Mandre
	<[e-mail]>.

1999-01-11  Markku Rossi  <[e-mail]>

	* b_string.c (method): Fixed the append() method to accept also
	integer arguments.

1999-01-08  Markku Rossi  <[e-mail]>

	* js.c (iofunc_close): Fixed a memory leak by freeing the
	context.

1998-11-25  Markku Rossi  <[e-mail]>

	* js.c (js_create_interp): Added a sanity check to assure that the
	js.h and jsint.h APIs share a common view about the node size.

	* js.h (struct js_type_st): Changed the JSType to be compatible
	with the internal JSNode.

	* operands.def: Changed the with-chain to use a JSUIntAlign count
	instead of a JSUInt32 count.

	* jsint.h: New integer type JSUIntAlign that can be used to align
	structures on correct byte boundaries.
	(struct js_heap_memory_block_st): Changed to use JSUIntAlign
	integers instead of JSUInt32s.  Now the memory allocation seems to
	work on Alpha machines.

1998-10-26  Markku Rossi  <[e-mail]>

	* vmswt0.c (js_vm_switch0_exec): Added support for anonymous
	functions.

	* vmswitch.c (js_vm_switch_exec): Added support for anonymous
	functions.

	* vmjumps.c (js_vm_jumps_exec): Added support for anonymous
	functions.

	* vm.c (js_vm_execute): Added support for anonymous functions.

	* jsint.h: Added argument `anonymous_function_offset' to
	JSVMExecute.  All uses changed.

	* operands.def: Tagged all symbol and jump operands with
	comments.  Now these operands can be handled automatically.
	New operands `load_global_w' and `jsr_w'.
	Added support for function pointers.

	* js.c (js_create_interp): Pass the `options.warn_undef' to the
	virtual machine.

	* jsint.h (JS_OPERAND_CMP_EQ): Fixed to handle the `object _OP_
	string / number' cases.  Now the == and != is ECMA compatible.
	(JS_IS_PRIMITIVE_VALUE): New macro to check whether the argument
	is a primitive value or not.

	* utils.c (js_vm_to_primitive): Implement ToPrimitive() type
	conversion.

1998-10-20  Markku Rossi  <[e-mail]>

	* js.c (js_global_method_delete): New function to delete the user
	defined global method from the memory.

	* jsint.h (JS_SUBROUTINE_CALL): Fixed to check that we have
	enought stack space for yet another subroutine call.  The same
	thing is also checked in the `locals' operand, but some functions
	don't use any local variables, and therefore, the stack usage
	wasn't ever checked.

	* operands.def: Fixed `locals' to use the
	JS_RESERVE_STACK_FOR_FUNCTION preprocessor constant.

1998-10-16  Markku Rossi  <[e-mail]>

	* jsint.h (JS_IS_FINITE): New macro to determine whether a number
	node is a finite number.

	* b_date.c: Implemented MakeTime(), MakeDay(), MakeDate(), and
	TimeClip() operators.
	Implemented the global method invocation of the Date()
	constructor.

	* b_regexp.c (new_proc): Fixed to work with 0 arguments.

1998-10-12  Markku Rossi  <[e-mail]>

	* operands.def: Cleaned up namespace by fixing load_property's
	goto labels.
	Fixed call_method to lookup the methods also from the prototypes
	of string, array, and func built-in objects.

1998-10-07  Markku Rossi  <[e-mail]>

	* heap.c: Optimized the heap memory consumption by fixing the
	block headers and the freelist block handling.  The total savings
	in the memory usage (with the js_vm_make_function() fix) are about
	15 %.

	* jsint.h (js_vm_make_function): Fixed a typo that caused us to
	allocate one JSVirtualMachine for each function, instead of one
	JSFunction.
	(struct js_heap_memory_block_st): Optimized the header from 12
	bytes to 4 (on 32bit machines).
	(struct js_heap_freelist_block_st): Header for the memory block
	when it is on the freelist.

1998-10-05  Markku Rossi  <[e-mail]>

	byte-code operand execution.

	* b_object.c (method): Implemented toString() method.

	* alloc.c (js_strdup_i): Added const to the dupped string
	argument.

	* operands.def: Fixed the operand `call_method' to call the method
	from the object's constructor, if the object hasn't redefined the
	called method.

	* regex.c: Updated regex.{c,h} files from the glibc-2.0.96.  Added
	some re-entrancy fixed to regex.c.

1998-09-29  Markku Rossi  <[e-mail]>

	* heap.c (BLOCK_SIZE): Changed to 200 * 1024 bytes on 32 bit and
	bigger systems.
	(js_vm_alloc): Fixed the `alloc_size' calculation for cases when
	it is bigger than BLOCK_SIZE.  Now we can re-use those bigger
	blocks more efficiently.

1998-09-22  Markku Rossi  <[e-mail]>

	* js.c (js_create_interp): Added debug call for
	js_alloc_dump_blocks() to find out how much memory one interpreter
	takes.  Maybe the heap.c:BLOCK_SIZE should be an option in the
	JSInterpOptions.

1998-09-21  Markku Rossi  <[e-mail]>

	* b_regexp.c (js_builtin_RegExp): Removed the re_set_syntax()
	call, since the correct default is already present in the regex.c.

	* regex.c: Initialized the default syntax to RE_SYNTAX_GNU_AWK.
	This removes the re-entrancy problem from b_regexp.c.

	* operands.def: ECMA compliancy fixes for the `and', `or', `xor',

	string.

	* iostream.c (js_iostream_file): Added argument <do_close> that
	specifies whether the actual `FILE *' file pointer will be closed
	when the stream is destroyed.  Normally, we don't want to close
	stdin, stdout, or stderr when the interpreter is destoyed.

1998-08-25  Markku Rossi  <[e-mail]>

	* jsint.h (struct js_vm_st): New flag `verbose_stacktrace'.

	* operands.def: Added a new slot to the stack frame: args_fix.
	The args_fix holds the relocation information from the `min_args'
	operand.  The operand `return' needs that information when it is
	returning from a function that was called with too few arguments.
	All uses of STACKFRAME were changed.

1998-08-19  Markku Rossi  <[e-mail]>

	* b_system.c (property): New property `lineBreakSequence'.  The

	Changed the exec functions of different dispatchers to accept one
	extra parameter: the object that should be used as the `this'
	object.

1998-08-17  Markku Rossi  <[e-mail]>

	* js.h: Added DllExport's to all public API functions.  These must
	be exported explicitly on w32.

	* b_file.c (method): Ported to w32.  The member
	struct_st.st_blksize is not present there.
