Bug #: 55292
Summary: libsanitizer doesn't support x32
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: hjl.to...@gmail.com
sanitizer_common/sanitizer_linux.cc has
void *internal_mmap(void *addr, uptr length, int prot, int flags,
int fd, u64 offset) {
#if __WORDSIZE == 64
return (void *)syscall(__NR_mmap, addr, length, prot, flags, fd, offset);
#else
return (void *)syscall(__NR_mmap2, addr, length, prot, flags, fd, offset);
#endif
}
uptr internal_filesize(fd_t fd) {
#if __WORDSIZE == 64
struct stat st;
if (syscall(__NR_fstat, fd, &st))
return -1;
#else
struct stat64 st;
if (syscall(__NR_fstat64, fd, &st))
return -1;
#endif
return (uptr)st.st_size;
}
They are incorrect for x32.
