compiler: mark generated struct/array types as incomparable

    The recent change to generate type functions for more types with
    identity comparisons caused us to generate some unnecessary functions,
    and even caused a compiler crash on Solaris due to phase ordering.
    Avoid this by marking all generated and uncompared struct and array

    for them.

7 years ago[arm] Replace command-line option .def files with single definition file
Richard Earnshaw [Wed, 11 Jan 2017 14:39:00 +0000 (14:39 +0000)]
[arm] Replace command-line option .def files with single definition file

The files arm-cores.def, arm-fpus.def and arm-arches.def are parsed and
used in several places and the format is slightly awkward to maintain
as they must be parsable in C and by certain scripts.  Furthermore,
changes to the content that affects every entry is particularly awkward for
dealing with merges.

This patch replaces all three files with a single file that specifies all
the command-line related definitions in a new format that allows for better
checking for consistency as well as (hopefully) easier to merge changes.

The awk script used to parse it is relatively complicated, but should be
pretty portable.  It works by parsing in all the data and then operating
one of a number of possible sub-commands to generate the desired output.

The new method picked up one error.  The CPU descriptions referred to an
architecture ARMv5tej which was not supported by -march.  This has been
fixed by adding the relevant entry to the architecture list.

* config.gcc: Use new awk script to check CPU, FPU and architecture
parameters for --with-... options.
