2002-05-21  Martin Baulig  <martin@gnome.org>

	Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
	file for all assemblies.  Currently, the JIT doesn't put all methods
	from a single assembly into a continuous region of memory.  We were
	previously creating valid DWARF 2 files for this, but unfortunately
	GDB's symbol tables get messed up when it reads more than one such file.

	* debug-private.h (AssemblyDebugInfo): Moved `f', `producer_name',
	`next_idx', `methods', `type_hash', `source_files' and `format'

	numbers, we still need to generate the IL offsets here. Emit line numbers
	for `prologue_end_offset' (the first line of actual code) and 
	`epilogue_begin_offset' (the line of the method's closing brace).
	Don't crash if cfg->bblocks [i].forest is NULL.

	Initialize the newly added fields.

	* debug-stabs.c: Record first and last line, emit filename info at the

2002-03-23  Martin Baulig  <martin@gnome.org>

2002-03-14  Martin Baulig  <martin@gnome.org>

	* debug.c (MonoDebugFormat): New public enums specifying which debugging
	format to use.
	(mono_debug_open_file): Added MonoDebugFormat argument.
	(mono_debug_make_symbols): Don't take an argument to make it easier to call
	this function from GDB. It's now safe to call this function multiple times;
	it'll always write a complete debugging file.

	* debug.c: Splitted this file into a general part which remains in this file
	and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
	All public functions now call a corresponding format specific function.

	* debug.c: The following changes are private to debug.c:
	(AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
	(record_line_number, debug_generate_method_lines): New private functions.
	(mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
	calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
	mono_debug_open_assembly_dwarf2).
	(mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
	now safe to call this function multiple times.
	(mono_debug_get_type): New public function. This takes a `MonoClass *' and
	returns an unique index for this type. It's used to ensure that we only write
	each class once to the debugging file.
	(mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
	data structure, but don't directly write to the debugging file. This is done
	later from mono_debug_write_assembly().

	* jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
	debugging output. Call mono_debug_close() on cleanup if necessary.

2002-03-14  Martin Baulig  <martin@gnome.org>

	* debug-private.h: New private header file.

	* debug-stabs.c: Added the stabs type generation stuff which was

	change soon.

2002-03-13  Martin Baulig  <martin@gnome.org>

	* debug-stabs.c, debug-dwarf2.c: New files containing my new
	debugging code. They're now in CVS, but not yet used anywhere.

2002-03-10  Martin Baulig  <martin@gnome.org>

	* emit-x86.c (arch_compile_method): When emitting stabs debugging
	output, put a nop instruction at the start of all functions so that
	the adresses won't change when using --debug.

	* debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
	the bytecode area, stabs needs a line number in the .il file. Use the
	new info->moffsets to get the line number.
	(AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
	`moffsets' is an array of `total_lines' fields (total number of lines
	in the .il file); for each line in the .il field, this array contains
	the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
	of a method and 0 otherwise.
	(debug_load_method_lines): Read the whole .il file and initialize the

	* x86.brg: added some rules to optimize code

	* testjit.c (get_address): use a binary search to get the address
	(main): added an option to debug the jit (-d)

	* testjit.c: better/faster align code. Handle ldloc.s and stloc.s.

2001-09-17  Miguel de Icaza  <miguel@ximian.com>

	* testjit.c (mono_compile_method): Provide better error reporting.

2001-09-17  Dietmar Maurer  <dietmar@ximian.com>

	* testjit.c (tree_get_address): impl. to fix address bug
	(tree_get_address): make sure that we can only jump to the first
	instruction of a tree.

	* x86.brg: emit real code for calls

	* testjit.c (create_jit_trampoline): creates a function to trigger jit
	compilation.
	(mono_compile_method): reversed argument order

2001-09-15  Dietmar Maurer  <dietmar@ximian.com>

	* x86.brg (stmt): don't emit unnecessary register moves

	* testjit.c (tree_allocate_regs): free registers earlier

2001-09-14  Dietmar Maurer  <dietmar@ximian.com>

	* x86.brg: branch addresses are now resolved

	* testjit.c (compute_branches): compute address of branches

	* x86.brg: emit real x86 instructions

	* testjit.c: call objdump to disassemble the output

2001-09-13  Dietmar Maurer  <dietmar@ximian.com>

	* x86.brg: use the right offsets to access local variables
	and arguments.

	* emit-x86.c: only save/restore callee saved registers if they are
	really modified.

	* testjit.c (tree_allocate_regs): use the new MonoRegSet to
	allocate registers.
	(mono_compile_method): changed the tree for mothod calls

	* regset.h: impl.
	
	* regset.c: impl.
	

2001-09-10  Miguel de Icaza  <miguel@ximian.com>

	* x86.brg: Use Unix assembly syntax.

	* emit-x86.c: support code, should be moved

	* testjit.c: Use GPtrArrays instead of GLists, as those are very
	inefficient at appends.

	* Renamed `create_new_leave' to `create_new_leaf'
