Remove ARM old-ABI glibc ports support, part 1
- From: "Joseph S. Myers" <joseph at codesourcery dot com>

- Subject: Remove ARM old-ABI glibc ports support, part 1
I've applied this patch with the first part of removing support for ARM
old-ABI from glibc ports. The preconfigure script is made to give an
error for old-ABI targets; files that are not used for EABI are removed;
the EABI check_pf.c, which just included the generic Linux version to
override a special old-ABI version, is also removed.
There's still more to do to complete the removal: various __ARM_EABI__
conditionals can go, and the directory structure should be flattened so
that there are no longer /eabi/ directories (merging files where multiple
versions of the same file still exists; in particular, merging
sysdeps/unix/sysv/linux/arm/sysdep.h and the /eabi/ version, so removing
the old-ABI version of the syscall macros (one of the various sources of
confusion where people look at old-ABI code and wrongly think that's how
to do things for ARM; this patch at least helps eliminate the confusion
where people configure for arm-*-linux-gnu, thinking that's the target
triplet to use for ARM).

- * 31-24 23-16 15-8 7-0

- * 1000 FPPC hardware
- * 0001 FPE 400
- * 1001 FPA hardware

- *
- * 7 - 5 4 3 2 1 0
- * | reserved | INX | UFL | OFL | DVZ | IVO |
- *
- * where a `1' bit in the enable byte means that the trap can occur, and
- * a `1' bit in the flags byte means the exception has occurred.
- *
- * The exceptions are:
- *
- * IVO - invalid operation
- * DVZ - divide by zero
- * OFL - overflow
- * UFL - underflow
- * INX - inexact (do not use; implementations differ)
- *
- * The system control byte looks like this:
- *
- * 7-5 4 3 2 1 0
- * | reserved | AC | EP | SO | NE | ND |
- *
- * where the bits mean
- *
- * ND - no denormalised numbers (force them all to zero)
- * NE - enable NaN exceptions
- * SO - synchronous operation
- * EP - use expanded packed-decimal format
