The commit "arm: Split BE/LE abilist"
(1673ba87fefe019c834c09d33673d1d453ea698d) changed the soft-fp order for
ARM selection when __SOFTFP__ is defined by the compiler.
On 2.30 the sysdeps order is:
2.30
sysdeps/unix/sysv/linux/arm
sysdeps/arm/nptl
sysdeps/unix/sysv/linux
sysdeps/nptl
sysdeps/pthread
sysdeps/gnu
sysdeps/unix/inet
sysdeps/unix/sysv
sysdeps/unix/arm
sysdeps/unix
sysdeps/posix
sysdeps/arm/nofpu
sysdeps/ieee754/soft-fp
sysdeps/arm
sysdeps/wordsize-32
sysdeps/ieee754/flt-32
sysdeps/ieee754/dbl-64
sysdeps/ieee754
sysdeps/generic
While on master is:
sysdeps/unix/sysv/linux/arm/le
sysdeps/unix/sysv/linux/arm
sysdeps/arm/nptl
sysdeps/unix/sysv/linux
sysdeps/nptl
sysdeps/pthread
sysdeps/gnu
sysdeps/unix/inet
sysdeps/unix/sysv
sysdeps/unix/arm
sysdeps/unix
sysdeps/posix
sysdeps/arm/le
sysdeps/arm
sysdeps/wordsize-32
sysdeps/ieee754/flt-32
sysdeps/ieee754/dbl-64
sysdeps/arm/nofpu
sysdeps/ieee754/soft-fp
sysdeps/ieee754
sysdeps/generic
It make the build select some routines (fadd, fdiv, fmul, fsub, and fma)
on ieee754/flt-32 and ieee754/dbl-64 that requires fenv support to be
correctly rounded which in turns lead to math failures since the
__SOFTFP__ does not have fenv support.
With this patch the order is now:
sysdeps/unix/sysv/linux/arm/le
sysdeps/unix/sysv/linux/arm
sysdeps/arm/nptl
sysdeps/unix/sysv/linux
sysdeps/nptlsysdeps/pthread
sysdeps/gnu
sysdeps/unix/inet
sysdeps/unix/sysv
sysdeps/unix/arm
sysdeps/unix
sysdeps/posix
sysdeps/arm/le/nofpu
sysdeps/arm/nofpu
sysdeps/ieee754/soft-fp
sysdeps/arm/le
sysdeps/arm
sysdeps/wordsize-32
sysdeps/ieee754/flt-32
sysdeps/ieee754/dbl-64
sysdeps/ieee754
sysdeps/generic
Checked on arm-linux-gnuaebi.

It adds the missing Implies for armv7, armv6, armv6t2 after the
commit 1673ba87fefe019c. Without the Implies a build with the
compiler targeting the aforementioned architecture does not select
the arch-specific optimization including the ifunc selectors.
I checked with a build against armv5, armv6, armv6t2, armv7, and
armv7-neon for both LE and BE. For armv6 and armv7 I also checked
that both sysdeps selection and the resulting implementation built
is the expected ones.

The fix for BZ#18231 requires new symbols only for armeb. This patch
adds the required folder and files for both BE and LE abilist. No
semantic changes are expected.
Checked with check-abi for arm-linux-gnueabihf and armeb-linux-gnueabihf.
* sysdeps/arm/preconfigure.ac: Set machine based on endianness.
* sysdeps/arm/preconfigure: Regenerate.
* sysdeps/arm/be/Implies: New file.
* sysdeps/arm/be/armv6/Implies: Likewise.
* sysdeps/arm/be/armv6t2/Implies: Likewise.
