is due to gccgo unable to understand FreeBSD `struct stat', and they
use bitfields at the end of the structure for padding:
struct stat {
[...]
#if __BSD_VISIBLE
struct timespec st_birthtimespec; /* time of file creation */
/*
* Explicitly pad st_birthtimespec to 16 bytes so that the size of
* struct stat is backwards compatible. We use bitfields instead
* of an array of chars so that this doesn't require a C99 compiler
* to compile if the size of the padding is 0. We use 2 bitfields
* to cover up to 64 bits on 32-bit machines. We assume that
* CHAR_BIT is 8...
*/
unsigned int :(8 / 2) * (16 - (int)sizeof(struct timespec));
unsigned int :(8 / 2) * (16 - (int)sizeof(struct timespec));
#else
time_t st_birthtime; /* time of file creation */
long st_birthtimensec; /* nsec of file creation */
unsigned int :(8 / 2) * (16 - (int)sizeof(struct __timespec));
unsigned int :(8 / 2) * (16 - (int)sizeof(struct __timespec));
#endif
};
Which result in:
% grep 'type _stat ' gen-sysinfo.go
// type _stat struct { st_dev uint32; st_ino uint32; st_mode uint16;
st_nlink uint16; st_uid uint32; st_gid uint32; st_rdev uint32;
st_atimespec _timespec; st_mtimespec _timespec; st_ctimespec
_timespec; st_size int64; st_blocks int64; st_blksize uint32; st_flags
uint32; st_gen uint32; st_lspare int32; st_birthtimespec _timespec;
_f0 INVALID-bit-field; _f1 INVALID-bit-field; }
However, gcc trunk' C fe is able to parse this definition.
continuing to dig for other errors.
