If -fprofile-update=atomic is used, then the target must provide atomic operations for the counters of the type returned by get_gcov_type(). This is a 64-bit type for targets which have a 64-bit long long type. On 32-bit targets this could be an issue since they may not provide 64-bit atomic operations. Allow targets to override the default type size with the new GCOV_TYPE_SIZE target macro.gcc/ * config/sparc/rtemself.h (GCOV_TYPE_SIZE): Define. * coverage.c (get_gcov_type): Use GCOV_TYPE_SIZE. * defaults.h (GCOV_TYPE_SIZE): Define default. * tree-profile.c (gimple_gen_edge_profiler): Use precision of gcov_type_node.

The patch is incorrect. With this patch the compiler view of the gcov type doesn't match the libgcov view. I have to do some changes in libgcov.h in this area:
#if LONG_LONG_TYPE_SIZE > 32 typedef signed gcov_type __attribute__ ((mode (DI))); typedef unsigned gcov_type_unsigned __attribute__ ((mode (DI))); #else typedef signed gcov_type __attribute__ ((mode (SI))); typedef unsigned gcov_type_unsigned __attribute__ ((mode (SI))); #endif -- embedded brains GmbH Herr Sebastian HUBER Dornierstr. 4 82178 Puchheim Germany email: sebastian.hu...@embedded-brains.de phone: +49-89-18 94 741 - 16 fax: +49-89-18 94 741 - 08 Registergericht: Amtsgericht München Registernummer: HRB 157899 Vertretungsberechtigte Geschäftsführer: Peter Rasmussen, Thomas Dörfler Unsere Datenschutzerklärung finden Sie hier: https://embedded-brains.de/datenschutzerklaerung/
