            Bug ID: 106036
           Summary: Missing stdint.h include in libgcc/libgcov.h
           Product: gcc
           Version: 12.1.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: gcov-profile
          Assignee: unassigned at gcc dot gnu.org
          Reporter: kacper.slominski72 at gmail dot com
                CC: marxin at gcc dot gnu.org
  Target Milestone: ---

The libgcc/libgcov.h header (and users of it) do not include stdint.h before
using int64_t and uint64_t (via typedefs in gcc/gcov-io.h).

Looking a bit deeper, gcc/tsystem.h includes a bunch of libc headers but omits
stdint.h, which, on glibc, gets inadvertently brought in by stdlib.h and
sys/types.h, but POSIX does not specify that it needs to.

Well, where exactly do you see an error? In the building of libgcc?

Okay, this seems to have been a false alarm, sorry for that! Our C library was
missing the typedef for intptr_t in unistd.h, which POSIX does specify. After
adding that, libgcc compiled without problems. It appears that the typedefs in
gcc/gcov-io.h are either not compiled in at all, or are only compiled in when
stdint.h has been included before (I haven't looked into which of the two
happens exactly).

Feel free to close this as RESOLVED INVALID and disregard the patch I sent to
gcc-patches, and again, sorry for the false alarm.

Thanks for clarification, closing as invalid.
