            Bug ID: 58692
           Summary: aarch64 arm_neon.h functions are not documented
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: lennox at cs dot columbia.edu

The GCC manual documents all the intrinsic functions supported by arm_neon.h on
the arm architecture, in terms of the assembly code each function is expected
to generate.

The aarch64 architecture extends arm_neon.h with over a thousand new intrinsic
functions.  However, these additional functions are not documented.  While the
meaning of many of them can be inferred from their names and function
arguments, they should actually be documented.
