mpn/sh/*.s: Transform to m4-ccas format.

Hello,

In version 4.2.1,
cofigure script which seeks PROLOGUE() or so failes to
detect that sh(SuperH)
has native code, because files under mpn/sh/ are plain
assembler file.

I changed some files to make them processed via m4-ccas.
All "make check" tests passed at least on sh3(=a
variant of sh)linux platform.

Copyright notice has left untouched, because this is only
formatting change.
The new file, mpn/sh/sh-defs.m4, carries FSF's copyright
notice as other m4
files which are used as a reference do.

Plese notify me if my copyright notice or explicit
assignment is needed.
I don't think there is my own property, though.

Best regards,
/yoshii

Re: mpn/sh/*.s: Transform to m4-ccas format.

It seems odd that the configure script doesn't detect the .s
files.  I
tested "configure --host=sh2-unknown-linux-gnu"
and it worked as it
should.  (Admittedly, I did that on a non-SH non-Linux
system.)

What is your evidence for that configure really fails to
detect the
SH assembly code?

Thank you for your reply.

Yes it detects .s files, but doesn't detect that
mpn_{add,sub}_n functions
are defined.

> What is your evidence for that configure really fails

Please try this.
 $ ./configure --host=sh2-unknown-linux-gnu
 $ grep "define HAVE_NATIVE" config.h
This should produce following output.
 #define HAVE_NATIVE_mpn_add_n 1
 #define HAVE_NATIVE_mpn_sub_n 1
But, nothing cames out without the patch.

And, this results a problem in addsub_n.c.
# Sorry, I should have explained this first.

The file mpn/addsub_n.c have lines like following.
| #if HAVE_NATIVE_mpn_add_nc || !HAVE_NATIVE_mpn_add_n
|           acyo = mpn_add_nc (r1p + off, s1p + off, s2p +
off, this_n, acyo);
| #else
|           acyn = mpn_add_n (r1p + off, s1p + off, s2p +
off, this_n);
|           acyo = acyn + mpn_add_1 (r1p + off, r1p + off,
this_n, acyo);
| #endif

Without the fix, "then clause(?)" is selected
instead of "else clause"
because HAVE_NATIVE_mpn_add_n is not defined, 
But because mpn_add_nc() is also not defined, this symbol is
left in the
library as an unresolved symbol. This makes the library
useless.

Hope I could explain the issue this time....

Best regards,
/yoshii

The fix for that is http://gmplib
.org/patches/x86-fat.diff.

(The patch name might be confusing, it should be named
"gnulinux-linker-silliness.diff", perhaps.)
