Adhemerval Zanella Netto May 20, 2015, 2:19 p.m. UTC
Hi

This patch is another of the required adjustments for the fix for bz12683
(Race conditions in pthread cancellation) and the idea is to get rid of
assembly implementation for socket function for ports which uses socketcall.

This patch removes the socket.S implementation for all ports and replace
it by a C implementation using socketcall where it is required.  For ports
that implement the syscall directly, there is no change.

The patch idea is to simplify the socket function implementation that
uses the socketcall to be based on C implemetation instead of a pseudo
assembly implementation with arch specific parts.  All the affect
architectures (i386, microblaze, mips, powerpc, and sparc) have support
for 6 argument syscalls.

I have cross-build GLIBC for afore-mentioned ports and tested on i386,
x86_64, powerpc64le, arm, and aarch64.

Indeed, this is the only missing cross-compiler I forgot to create.  I will
remove its socket implementation and check with a cross-build.

Yes, this comments is out of place here.

I will remove them as well, thanks for this out.
