[LLVMdev] floating point exceptions in compare instructions
Looking at the llvm code I have the impression that ordered fp
comparisons should use exception throwing instructions. Is it true?
Thanks,
Rafael

Nope, you want non-trapping instructions. If you use trapping
instructions, C99 functions like isgreater will not work correctly with
NAN's.

How do I know when to use a trapping instruction? For example consider
this C function:
------------------------
int f(float a, float b) {
return a <= b;
}
------------------------
gcc uses fcmpes instead of fcmps...

chmod sftp command and setgid/setuid bit
...and we recently hit some sftp unexpected behavior:
https://savannah.gnu.org/support/?105838
when using chmod sftp client command
it appears that setuid / setgid bits are not handled on the server-side.
that when I
sftp> chmod 2775 afile
I would expect afile to show:
-rwxrwsr-x 1 openssh isgreat 0 2007-04-25 00:19 afile
but I get:
-rwxrwxr-x 1 openssh isgreat 0 2007-04-25 00:19 afile
just as if I had typed: "chmod 775 afile " on server-side.
As far as I understand sftp-server.c code is seems that
chmod(name, a->perm & 0777);
is responsible for this behavior...

LLVM-3.8.0 libcxx in-tree build fails with cmath error ::signbit has not been declared
Greetings!
I have been building llvm-3.6.x, 3.7.1 and 3.7.2 with (glibc-2.12.1, binutils-2.24, gcc-4.9.2) almost same set if CMake flags.
However while building LLVM-3.8.0 using same CMake flags I am observing projects/libcxx/include/cmath errors...
