John, I have added your microsecond clock changes (Mantis 7458) to VMMaker
on SqueakSource, and also added #primitiveUtdWithOffset as per earlier
thread on vm-dev.
Can you please follow up with the following:
1) Check in the new sq.h into Subversion (attached, and also on Mantis). This
is your updated sq.h plus one additional declaration for ioUtcWithOffset().
2) In your config.h for OS X and iPhone, add the following macro to override
the default VMMaker definition and point to your actual platform function:
#define ioMicroSecondClock ioMicroSeconds
3) Add the implementation for primitiveUtdWithOffset in OS X platform source
by adding the following macro in your config.h:
#define ioUtcWithOffset(clock, offset) setMicroSecondsandOffset(clock, offset)
And then implement the function as:
sqInt ioUtcWithOffset(sqLong *microSeconds, int *offset)
struct timeval timeval;
if (gettimeofday(&timeval, NULL) == -1) return -1;
long long seconds = timeval.tv_sec;
suseconds_t usec = timeval.tv_usec;
*microSeconds = seconds * 1000000 + usec;
*offset = localtime(&seconds)->tm_gmtoff;
Note, the above ioUtcWithOffset is tested only on Linux but should be
the same for OS X. I don't know if it would work for iPhone. If it does
not work, just skip step 3 above and #primitiveUtcWithOffset will give
a primitive failure at runtime.
