2007-09-04  Juan Cespedes  <cespedes@debian.org>

	* ltrace.h: Take arg_num out of arg_type_info
	* linux-gnu/*/trace.c: gimme_arg(): Add arg_num as argument
	* ltrace.c: check for existence of $HOME before using it
	* General: Small fixes (indentation)

2007-08-31  Juan Cespedes  <cespedes@debian.org>

	* General: Small fixes (indentation, typos, clean-up of code)
	* ltrace.c: Close output file on exit
	* ltrace.c: use getenv("HOME") instead of getpwuid(geteuid())->pw_dir
	* read_config_file.c, display_args.c: remove "ignore" argtype;
	  that's what "void" is for
	* packaging/debian/: misc fixes, sync with version 0.5-2
	* etc/ltrace.conf: added more system calls
	* testsuite/ltrace.minor/trace-clone.c: sleep(1) to avoid earlier
	  termination of process
	* sysdeps/linux-gnu/trace.c: trace_pid(): reverted Petr's patch
	  to wait for child to stop, as it stopped following clone()
	* process_event.c: Disable breakpoints before doing fork() (again!),
	  to make children work as expected

2007-05-10  Petr Machata  <pmachata@redhat.com>

	* Based on work of Supriya Kannery <supriyak@in.ibm.com>
	* wait_for_something.c, process_event.c: Tracing across exec.
	* sysdeps/linux-gnu/trace.c, ltrace.h: New interface was_exec.
 	* testsuite/ltrace.minor/trace-exec.c,
	testsuite/ltrace.minor/trace-exec.exp,
	testsuite/ltrace.minor/trace-exec1.c: Testcase for same.

2007-05-09  Petr Machata  <pmachata@redhat.com>

	* wait_for_something.c (wait_for_something): Interpret SIGILL,
	SIGEMT and SIGSEGV as valid breakpoint signals, if instruction
	pointer referes to breakpoint.
	* testsuite/ltrace.torture/ia64-sigill.s,
	* testsuite/ltrace.torture/ia64-sigill.exp: Testcase for same.
	IA64-centric, because the only reproducer is there.

2007-01-19  Petr Machata  <pmachata@redhat.com>

	* sysdeps/linux-gnu/trace.c (trace_pid): wait for child to stop,
	as indicated by ptrace documentation.
	* proc.c (open_pid): start the traced child again, it will have
	been stopped after trace_pid.  Fixes tracing with -p.
	* breakpoints.c: initialize proc->breakpoints always, don't wait
	untill it might be needed.  This renders a check in insert_breakpoint
	superfluous.  Fixes a sigsegvs experienced with -L.

2006-12-28  Eric Vaitl  <evaitl@cisco.com>

	* sysdeps/linux-gnu/mipsel/* Added mipsel support
	* debug.h Added printf format attribute to debug_
	* elf.h Added mips relocation data to struct ltelf
	* elf.c (do_init_elf) Read mips relocation data
	* elf.c (read_elf) On the mips loop through mips_gotsym 
	instead of relplt_count.
	* process_event.c (process_breakpoint) For the mips, 
	conditionally add a new breakpoint if the address of the 
	function changes because of lazy relocation. 
	* breakpoints.c (enable_all_breakpoints) For the mips, 
	reinsert breakpoints after the child has been started. 
	

2006-11-30  Petr Machata  <pmachata@redhat.com>

	* elf.c (elf_gnu_hash): renamed to private_elf_gnu_hash to avoid
	conflicts with non-static version from libelf.

2006-11-30  Petr Machata  <pmachata@redhat.com>

	* elf.c (in_load_libraries): removed unused variables
	bitmask_idxbits and shift.
	* elf.c (do_init_elf, opd2addr): use ARCH_SUPPORTS_OPD to
	determine whether to load/use .opd section
	* sysdeps/linux-gnu/*/arch.h: define ARCH_SUPPORTS_OPD accordingly
	* breakpoints.c (insert_breakpoint): rewrite loop to canonical for

	* read_config_file.c: count floating-point parameters to support ia64
	float parameter passing

	arg_type_info to gimme_arg rather than just the arg_num (necessary
	for float params on some architectures)
	* sysdeps/linux-gnu/ia64/trace.c: accommodate register renaming when
	fetching the parameters of a function after it has returned
	* sysdeps/linux-gnu/ia64/trace.c: support floating point parameters
