[ECOS] Problem compiling newnet with timing stats

[Paul Randall <prandall at delta-info dot com>]

Hi all,

I am having problems compiling the newnet (FreeBSD) template with
CYGDBG_NET_TIMING_STATS turned on in eCos 2.0.  I can compile and run
the original TCP/IP stack (OpenBSD) with timing stats with no problem.
During the make for newnet, I get the following errors:

It looks like the compile errors are coming from the START_STATS() and
FINISH_STATS() macros in param.h:

#ifdef CYGDBG_NET_TIMING_STATS
#define START_STATS()                                   \
    cyg_uint32 start_time, end_time, elapsed_time;      \
    HAL_CLOCK_READ(&start_time);
#define
FINISH_STATS(stats)
\

HAL_CLOCK_READ(&end_time);
\
    if (end_time < start_time)
{                                                        \
        elapsed_time = (end_time+CYGNUM_KERNEL_COUNTERS_RTC_PERIOD) -
start_time;       \
    } else
{
\
        elapsed_time = end_time -
start_time;                                           \

}
\
    if (stats.min_time == 0)
{                                                          \
        stats.min_time =
0x7FFFFFFF;                                                    \

}
\
    if (elapsed_time <
stats.min_time)                                                  \
        stats.min_time =
elapsed_time;                                                  \
    if (elapsed_time >
stats.max_time)                                                  \
        stats.max_time =
elapsed_time;                                                  \
    stats.total_time +=
elapsed_time;                                                   \
    stats.count++;
#else
#define START_STATS()
#define FINISH_STATS(X)
#endif

I tried moving the "cyg_uint32 start_time, end_time, elapsed_time;" line
before the "#define START_STATS()" and the template compiled ok, but
when I went to run a test, my viper locked up during the ethernet
initialization.

Any suggestions?
