Dear Maintainer,
The gnat patches applied to gcc-14 to support building with -D_TIME_BITS=64
-D_FILE_OFFSET_BITS=64 broke numerous tests in the gnat testsuite.
Analysis of the array39 test showed that the ada timespec record was
not correctly layed out. See:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114065
In s-c_time.ads, we have
type timespec is record
tv_sec : time_t range 0 .. OS_Constants.MAX_tv_sec; -- seconds
tv_nsec : nsec_t range 0 .. 999_999_999; -- nanoseconds
end record
but the struct __timespec64 is defined as follows:
#if __TIMESIZE == 64
# define __timespec64 timespec
#else
#include <endian.h>
/* The glibc Y2038-proof struct __timespec64 structure for a time value.
To keep things Posix-ish, we keep the nanoseconds field a 32-bit
signed long, but since the Linux field is a 64-bit signed int, we
pad our tv_nsec with a 32-bit unnamed bit-field padding.
As a general rule the Linux kernel is ignoring upper 32 bits of
tv_nsec field. */
struct __timespec64
{
__time64_t tv_sec; /* Seconds */
# if BYTE_ORDER == BIG_ENDIAN
__int32_t :32; /* Padding */
__int32_t tv_nsec; /* Nanoseconds */
# else
__int32_t tv_nsec; /* Nanoseconds */
__int32_t :32; /* Padding */
# endif
};
#endif
The nsec_t is currently defined using the size of the tv_nsec in
the __timespec 64 struct but this ignores the padding on big-endian
targets.
The attached patch fixes this issue.
Regards,
Dave Anglin
