/****************************************************************************

Explicit tracing
================

CYG_TRACE0( bool, msg );
CYG_TRACE1( bool, msg, arg1 );
CYG_TRACE2( bool, msg, arg1, arg2 );
....
CYG_TRACE8( bool, msg, .... [with 8 args] );

In general, the bool controls whether or not the tracing occurs for a
particular invocation of the macro.  The msg is a printf-style string,
though exactly which formats are supported depends on the underlying
implementation.  Typically, at least %d, %x, %08x, %c and %s will be
supported.  Of course a most compact implementation might print

  TRACE:z1dbuff.c[92]get_nextdata(): data pointer %x offset %d: 42BD8 1C

or some such, leaving you to work it out for yourself.

It is expected that the boolean would rarely actually be a complex
expression; it is more likely that it would either be "1", tracing being
controlled for the whole compilation unit or subsystem by means of the
CYGDBG_USE_TRACING symbol, or a local symbol for tracing over the whole
file, defined to 0 or to 1.  For runtime control of tracing in a debugging
session, it is typical to use symbols defined to expressions such as:

    static int xxx_trace = 0;
    #define TL1 (0 < xxx_trace)
    #define TL2 (1 < xxx_trace)

so you set xxx_trace to 1 to enable those messages conditioned by TL1
(trace level 1) and so on.

    CYG_TRACE1( TL1, "Major argument is %d", zz );
    CYG_TRACE4( TL2, "...minor details %d %d %d %d", m1, m2, m3 ,m4 );

To assist with the case where the same symbol or expression is used
throughout a compilation unit, the programmer can define the symbol
CYG_TRACE_USER_BOOL as they choose and then use convenience macros with the
suffix 'B' in the obvious manner:

    #define CYG_TRACE_USER_BOOL (xxx_trace > 0)
    CYG_TRACE2B( "Counters are %d, %d", countlo, counthi );

For the case where you just want to print a load of numbers in hex, or
decimal, convenience suffices X, D and Y are provided.  X uses %08x, D %d
and Y an unadorned %x for each argument.

    CYG_TRACE3D( TL2, m1, m2, d );
   
If you want to do something similar but with a little more comment, the
names (strictly spellings) of the variables you are printing can be used by
appending a V to the X, D or Y.

    CYG_TRACE3DV( TL2, m1, m2, d );

might output:

  TRACE:z1dbuff.c[92]get_nextdata(): m1=23 m2=-4 d=55

These conveniences can be combined, and they apply equally to tracing with
up to 8 variables; the B for Bool goes last:

     CYG_TRACE4DVB( i, i*i, i*i*i, i*i*i*i );

might output:

  TRACE:table.c[12]main(): i=3 i*i=9 i*i*i=27 i*i*i*i=81


Function Tracing
================

There are also facities for easily reporting function entry and exit,
printing the function arguments, and detecting returns without logging (or
without a value!).

The basic facility is

        CYG_REPORT_FUNCTION();

In C, place this between the local variable declarations and the first
statement or errors will ensue.  C++ is more flexible; place the macro as
the first line of all functions you wish to trace.  The following
variations are also provided:

  CYG_REPORT_FUNCTYPE( exitmsg )  provide a printf string for the type
                                  of the returned value
  CYG_REPORT_FUNCNAME( name )     supply a function name explicitly, for
                                  if __FUNCTION__ is not supported
  CYG_REPORT_FUNCNAMETYPE( name, exitmsg ) both of the above extensions

These are unconditional; the assumption is that if function reporting is
used at all it will be used for all functions within a compilation unit.
However, it is useful to be able to control function reporting at finer
grain without editing the source files concerned, at compile time or at
runtime.  To support this, conditioned versions (with suffix 'C') are
provided for the above four macros, which only procduce trace output if the
macro CYG_REPORT_USER_BOOL evaluates true.

  CYG_REPORT_FUNCTIONC()
  CYG_REPORT_FUNCNAMEC( name )
  CYG_REPORT_FUNCTYPEC( exitmsg )
  CYG_REPORT_FUNCNAMETYPEC( name, exitmsg )

You can define CYG_REPORT_USER_BOOL to anything you like before invoking
these macros; using a simple -DCYG_REPORT_USER_BOOL=0 or ...=1 on the
compiler command line would do the trick, but there is more flexibility to
be gained by something like:

  #define CYG_REPORT_USER_BOOL (reporting_bool_FOO)
  #ifdef TRACE_FOO
  int reporting_bool_FOO = 1;
  #else
  int reporting_bool_FOO = 0;
  #endif

where FOO relates to the module name.  Thus an external symbol sets the
default, but it can be overridden in a debugging session by setting the
variable reporting_bool_FOO.

Note that the condition applied to the initial CYG_REPORT_FUNC...() macro
controls all function-related reporting (not tracing) from that function;
the underlying mechanisms still operate even if no output is created.  Thus
no conditioned variants of CYG_REPORT_FUNCARG[s] nor of CYG_REPORT_RETURN
are needed.

Examples:
    int myfunction()
    {
        CYG_REPORT_FUNCTYPE( "recode is %d" );

A function return is traced using

    CYG_REPORT_RETURN()         a void return
    CYG_REPORT_RETVAL( value )  returning a value

With the CYG_REPORT_FUNCTYPE example, the latter might produce a message
like:

  TRACE:myprog.c[40]fact(): enter
  TRACE:myprog.c[53]fact(): retcode is 24

It is also useful to trace the values of the arguments to a function:
        CYG_REPORT_FUNCARGVOID          confirms that the function is void
        CYG_REPORT_FUNCARG1( format, arg )              printf-style
                to
        CYG_REPORT_FUNCARG8( format, arg1...arg8 )      printf-style

The CYG_REPORT_FUNCARG[1-8] macros are also offered with the convenience
extensions: D, X, or Y, and V like the explicit tracing macros.  For
example:

    int fact( int number )
    {
        CYG_REPORT_FUNCTYPE( "recode is %d" );
        CYG_REPORT_FUNCARG1DV( number );
        int result = number;
        while ( --number > 1 )  result *= number
        CYG_REPORT_RETVAL( result );
        return result;
    }

might produce:

  TRACE:myprog.c[40]fact(): enter
  TRACE:myprog.c[40]fact(): number=4
  TRACE:myprog.c[53]fact(): retcode is 24

If no exit message is provided, a default of %08x is used.


General Configury
=================

If CYGDBG_INFRA_DEBUG_FUNCTION_PSEUDOMACRO is *not* defined, it is assumed
that __PRETTY_FUNCTION__ or equivalents do not exist, so no function name
tracing is possible; only file and line number.

If CYGDBG_INFRA_DEBUG_TRACE_MESSAGE is *not* defined, the message and
arguments to all tracing macros are not used; only "execution was here"
type information, by file, function and line number, is available.  This
can greatly reduce the size of an image with tracing disabled, which may be
crucial in debugging on actual shipped hardware with limited memory.

If configured for buffered tracing then CYG_TRACE_PRINT() can be used to
output the contents of the trace buffer on demand.

CYG_TRACE_DUMP() outputs a form of "core dump" containing info on the
scheduler and threads at the time. This information will be invalid if
the kernel is not running.

C/C++: in C++ the function reporting is implemented using a class object
with a destructor; this allows reporting of a return which has not been
explicitly reported, and detection of accidental multiple return reports.
This helps you write the function reporting correctly.  In C it is not
possible to be so sophisticated, so the implementation is not so helpful in
detecting errors in the use of the tracing system.

Note that for all of the above variations, the internal API to the
functions which are called in consequence of tracing remains the same, so
these variations can be mixed in the same executable, by configuring the
tracing macros differently in different compilation units or subsystems.

---------------------------------------------------------------------------

Internal Documentation
======================

The required functions which are used by the tracing macros are

    externC void
    cyg_tracenomsg( const char *psz_func, const char *psz_file, cyg_uint32 linenum );
    
    externC void
    cyg_tracemsg( cyg_uint32 what, 
                  const char *psz_func, const char *psz_file, cyg_uint32 linenum, 
                  const char *psz_msg );
    
    externC void
    cyg_tracemsg2( cyg_uint32 what, 
                   const char *psz_func, const char *psz_file, cyg_uint32 linenum, 
                   const char *psz_msg,
                   CYG_ADDRWORD arg0,  CYG_ADDRWORD arg1 );
    // extended in the obvious way for 4,6,8 arguments

These functions should expect psz_func and psz_file to possibly be NULL in
case those facilities are not available in the compilation environment, and
do something safe in such cases.  A NULL message should really be dealt
with safely also, just logging "execution here" info like cyg_tracenomsg().

Discussion of possible underlying implementations
-------------------------------------------------

It is intended that the functions that get called can simply print the info
they are given in as fancy a format as you like, or they could do the
printf-type formatting and log the resulting text in a buffer.  They get
told the type of event (function-entry, function-arguments, function-exit
or plain tracing info) and so can perform fancy indenting, for example, to
make call stack inspection more obvious to humans.  It is also intended
that a more compact logging arrangement be possible, for example one which
records, in 32-bit words (CYG_ADDRWORDs), the addresses of the file,
function and msg strings, the line number and the arguments.  This has the
implication that the msg string should not be constructed dynamically but
be static ie. a plain quoted C string.  The number of arguments also must
be recorded, and if it is chosen to save string arguments in the buffer
rather than just their addresses (which could be invalid by the time the
logged information is processed) some flagging of which arguments are
strings must be provided.  The system could also be extended to deal with
floats of whichever size fir in a CYG_ADDRWORD; these would probably
require special treatment also.  With these considerations in mind, the
maximum number of parameters in a single trace message has been set to 8,
so that a byte bitset could be used to indicate which arguments are
strings, another for those which are floats, and the count of arguments
also fits in a byte as number or a bitset.
