In reply to the thread ending with: http://gcc.gnu.org/ml/gcc-patches/2013-11/msg02069.html
and bugs: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54040 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=59346 Changing s-osinte-posix.adb - tv_nsec => long (Long_Long_Integer (F * 10#1#E9))); + tv_nsec => time_t (Long_Long_Integer (F * 10#1#E9))); breaks the build for kFreeBSD and Hurd too (in addition to hpux and solaris). Note that POSIX specified tv_nsec to be long (i.e. 64 bit), see: http://pubs.opengroup.org/onlinepubs/009695299/basedefs/time.h.html The <time.h> header shall declare the structure timespec, which has at least the following members: time_t tv_sec Seconds. long tv_nsec Nanoseconds. Additionally Linux/kFreeBSD/Hurd all defines struct timespec in time.h as follows: /* POSIX.1b structure for a time value. This is like a `struct timeval' but has nanoseconds instead of microseconds. */ struct timespec { __time_t tv_sec; /* Seconds. */ __syscall_slong_t tv_nsec; /* Nanoseconds. */ }; So defining tv_nsec to be time_t is completely wrong. The problem seems to be present only for the x32 architecture, so why not make a special-case solution for that arch. Obviously x32 is non-POSIX compliant since long is 32 bits, resulting in tv_nsec being 32 bits where it needs to be 64 bits. Isn't it possible to handle the differences for x32 with a s-osinte-linux-x32.ads file, even with s-osinte-posix.adb stays intact? Then ther changes would be limited to: * s-linux-x32.ads: New file. * s-osprim-x32.adb: Likewise. * gcc-interface/Makefile.in (LIBGNAT_TARGET_PAIRS): Replace s-linux.ads with s-linux-x32.ads, s-osprim-posix.adb with s-osprim-x32.adb for x32. and the rest would be obsolete: * s-linux.ads (time_t): New type. * s-linux-alpha.ads (time_t): Likewise. * s-linux-hppa.ads (time_t): Likewise. * s-linux-mipsel.ads (time_t): Likewise. * s-linux-sparc.ads (time_t): Likewise. * s-osinte-linux.ads (time_t): Mark it private. Replace long with System.Linux.time_t. (timespec): Replace long with time_t. * s-osinte-posix.adb (To_Timespec): Likewise. * s-taprop-linux.adb (timeval): Replace C.long with System.OS_Interface.time_t. and * s-osinte-hpux.ads (timespec): Change type of tv_nsec field to time_t. * s-osinte-kfreebsd-gnu.ads (timespec): Likewise. * s-osinte-solaris-posix.ads (timespec): Likewise. Possible content in s-osinte-linux-x32.ads would be: type tv_nsec_t is private; type tv_nsec_t is new Long_Long_Integer; type timespec is record tv_sec : time_t; tv_nsec : tv_nsec_t; end record; pragma Convention (C, timespec);
