[GNU Tools Cauldron 2014] GNU C library BOF

[Prathamesh Kulkarni]

Hi,
    I have written notes for "GNU C library" BOF presented at
Cauldron. I would be grateful if you would review it for me.

GNU C library BOF

Author: Carlos O'Donell

    glibc (GNU C library) is available on most GNU systems
with the Linux kernel. It follows all relevant standards including
ISO C11 and POSIX.1-2008. It's designed to be a portable
and high performance library.

Highlights of BOF:

- Planning for glibc 2.21 and what work needs to be done
between the August -> January 2015 timeframe

- Discussions on issues regarding fmemopen, fd locking,
Wundef.

Alternate libm implementations:
- Red Hat is working on supporting alternate libm
implementation, with support for low precision and high precision.
- Intel is looking to add math functions that work on small vectors.

Address Sanitizer:
- glibc has been built with address sanitizer. Efforts are being
made to integrate it with the build system.

- Mentor Graphics planning to port glibc to NIOS II.
  It shall have to wait until Linux kernel patches are in a
  kernel release.

- AArch64 ILP32 ABI: Kernel patches currently in review.
  Work related to compiler is done.

- Port to OpenRISC.

- Port to NaCl (nptl)

Thanks,
Prathamesh
