This PR adds the following capability : each time a field is accessed with GET accessors functions, Field API prints a checksum. In addition, a backtrace of where the field was accessed from can be printed.
These two features are controlled with the following global variables (field_defaults_module.F90) :
GET_DEBUG_PRINT_CRC
GET_DEBUG_PRINT_LOCATION
Addresses are printed in hexadecimal, but can be converted to real code locations using addr2line.
An example of listing (taken from an ARPEGE run), after post-processing with addr2line :
Furthermore, this PR enables the calculation of CRC64 checksums without altering the field status (ie host/device freshness).
Please note that the backtrace feature (field_backtrace.c) is available only on Linux platforms; some help is required here to detect (with cmake) whether we are running on Linux.
You can test CRC/backtrace printing with the test_gang case :
