Update GMP-ECM to 6.3

[mabshoff]

Changes between ecm-6.2.1 and ecm-6.2.2:
* Updated build project files for Visual C by Brian Gladman, also adds
missing NTT_GFP_TWIDDLE_DI[FT]_BREAKOVER defines in VC parameter file
* Fixed uninitialised parameter to P-1 probability computation
* In tune.c : fixed generation of NTT_GFP_TWIDDLE_DI[FT]_BREAKOVER values,
avoid calling cputime() excessively often when timing short functions,
fixed access to uninitialised memory
* Fixed serious split infinitive in configure script (thanks Paul Leyland)
* Removed unnecessary carry propagation in x86_64 mulredc code, slight
speedup (thanks Philip McLaughlin)
* Fixed non-portable PIC code in x86_64/redc.asm
* Fixed problem with pattern matching host type names in configure.in
* Converted binary constants in spv.c and ntt_gfp.c to hexadecimal,
some assembler do not support binary constants

[was]

I think you may need the latest 6.3

 ./configure --with-gmp=/usr/local/
make -j
make -j check
and it passed
without specifing where gmp/mpir is , it got very confused , , they have their
search paths mixed up.

[mhansen]

There is a 6.3 spkg at ​http://sage.math.washington.edu/home/mhansen/ecm-6.3.spkg

I've checked that it works with MPIR 2.1.1 and all tests pass.

[leif]

Since Sage with MPIR 2.1.1 (#8664) requires updating to this package, I report at that ticket.

[leif]

Since MPIR 2.1.1 has a bug (see #9837), I've (successfully) built and tested Sage 4.6.prealpha3 (see #9343 and ​the NewPARI Wiki page) with GMP 5.0.1 and this new ECM 6.3 spkg on Ubuntu 10.04 x86_64 (Core2, gcc 4.4.3; parallel build from scratch with 32 jobs; native code with O3).

ptestlong passed all tests.

[leif]

It also passed ptestlong on the same machine with Sage 4.5.3.alpha2 and MPIR 2.1.1 (because the MPIR bug apparently only shows up in combination with the new PARI package, which isn't included in that Sage version).

Same for Fedora 13 x86 (Pentium 4 Prescott, gcc 4.4.4, parallel build with 6 jobs, rest dito).

[leif]

Suggested changes - NOT (yet) a Mercurial patch. (Minor fixes, some comments added, some clean-up.)

[leif]

I've added a reviewer patch (ordinary context diff) with some changes:

• Remove also the manual page of previous installations.
• Typo: rm -r -> rm -f (header file)
• Removed setting of CXXFLAGS, since we don't have C++ code.
• Don't overwrite CFLAGS if SAGE64=yes (instead, append). Removed -O2 -g in that case. Make use of CFLAG64 if set.
• Quote $SAGE_LOCAL in the parameters to configure, too.
• Use $MAKE in spkg-check, too.
• Some messages changed (e.g. all failures now starting with "Error"), some added.
• A few comments/notes added (SPKG.txt, spkg-install).

If you're ok with the changes, I can replace the diff with a Mercurial patch. Or simply merge them...

[leif]

New spkg: ​http://spkg-upload.googlecode.com/files/ecm-6.3.p0.spkg

md5sum: b9b1fcd5ebc2e3689fd379c1dba3a372 ecm-6.3.p0.spkg

New spkg based on Mike's with some more changes (than mentioned above).

Should be installed with the MPIR 2.1.3 spkg from #8664. See instructions there.

(Tested with Sage 4.6.1.alpha0 on Ubuntu 9.04 x86 and Ubuntu 10.04 x86_64.)

[leif]

SPKG "reviewer" patch, based on Mike's, i.e. ecm-6.3 vs. ecm-6.3.p0. For reference/review.

Well, I think these are the relevant parts:

...
checking whether we can link against GMP... yes
checking if gmp.h version and libgmp version are the same... (5.0.1/5.0.1) yes
checking for __gmpn_add_nc... yes
checking for __gmpn_mod_34lsub1... yes
checking for __gmpn_redc_1... no
...
configure: Using asm redc code from directory powerpc64
...

So it's probably an upstream problem, either MPIR or ECM.

Or should we pass -force_cpusubtype_ALL? (To the assembler?) I think rather not.

What happens on other PPCs?

Can you try installing it with GMP 5.0.1?

[leif]

Paul, perhaps you have an idea what's going wrong there (ECM trying to use "64-bit" instructions on MacOS X 10.4 PPC [G5], with MPIR 2.1.3).

[leif]

Jeroen, can you try configuring with --disable-asm-redc?

(The 64-bit PPC asm code is new in 6.3 btw.)

A remark about installing with GMP 5. On Gentoo I had to apply the following for it to compile

	# fixes for gmp-5
	sed -i "s:__GMP_BITS_PER_MP_LIMB:GMP_LIMB_BITS:g" bestd.c mpmod.c \
		schoen_strass.c sp.h || die "failed to patch files for gmp-5"

This is backward compatible with GMP 4.3. I am a bit surprised that with the stuff that mpir has deprecated, they didn't deprecate that as well.

Should I update the spkg / spkg patch to enable --disable-asm-redc (on MacOS X PPC 10.4 and perhaps 10.5, or simply PPC)?

IIRC we don't support 64-bit builds (SAGE64=yes) on PowerPC (and MacOS X < 10.6) anyway, and Apple doesn't support MacOS X 10.6 on PPCs.

Setting ABI=32 would perhaps also work.

[leif]

Any objections to enable (also) building a shared library?

(And also enabling the build of a static MPIR library, which is better for ECM?)

The build (outside of Sage) works.

Well, I'm a bit unsure what to do now. I can of course include the patch, but that does not what we actually want (it's just a work-around).

I think passing -Wa,-force_cpusubtype_ALL on MacOS PPCs should also work (which does not disable the assembly code, but avoids the odd assembler error, such that we get better performance).

Note that this worked on Dima's G4 with MPIR, so I expect it to work with a G5, too.

Don't know if G3s run into the same problem, or support these instructions. We then might have to really disable the code on PPCs < G4.

We could of course just test this in spkg-install, i.e. feed some extended instruction set assembly code to the assembler with -force_cpusubtype_ALL and see if we get an error before we disable the redc asm code. (I'd have to look what option gas takes on Linux PPC.)

Objections against adding yet another environment variable (ECM_EXTRA_OPTS, to add to ECM's configure, analoguous to PARI_EXTRA_OPTS), to ease working around potential problems showing up later?

[leif]

From my gas manpage (relevant for Linux PPC only):

...
       Target PowerPC options:
          [-mpwrx|-mpwr2|-mpwr|-m601|-mppc|-mppc32|-m603|-m604|
           -m403|-m405|-mppc64|-m620|-mppc64bridge|-mbooke]

          [-mregnames|-mno-regnames]
          [-mrelocatable|-mrelocatable-lib]
          [-mlittle|-mlittle-endian|-mbig|-mbig-endian]
          [-msolaris|-mno-solaris]
...

The options for other architectures in addition have more detailed descriptions, but unfortunately not the ones for PPC as the target. But it seems gas enables instruction set extensions by default.

---

P.S.: That the build works with -force_cpusubtype_ALL (without SAGE_CHECK=yes) doesn't necessarily mean we couldn't get illegal instruction exceptions when actually running the code.

Hmmm, we have to upgrade ECM because of the upgrade of MPIR / GMP:

Changes between ecm-6.2.3 and ecm-6.3:

• New assembly code for 64-bit PowerPC (thanks to Philip McLaughlin)
• Allow several processes to write to the same -save file
• More routines in new P+-1 stage 2 use multi-threading in OpenMP build
• Fixed incompatibility with GMP 5.0.0
• Fixed several bugs, and now check return value from malloc() calls
• Fixed linking of GMP which prevented successful builds under Darwin (and presumably other systems)
• Allow use of x86_64 asm code under MinGW

}}} I'll have to check my inbox for the details. I imported it on the 7th of July because it said it was compatible with GMP-5 and one of our user was using that. The user then reported that he still couldn't get ECM to build and I introduced the fix above the next day which solved the problem. A possibility is interference with by a patch to GMP Gentoo side.

On a positive note ECM 6.3 is the default in sage-on-gentoo since the 3rd of August so it has been extensively tested on x86, amd64 and ppc. However assembler code is at the user's discretion.

So, one (not me :-( )needs to explain this to the autoconf, I suppose

I went ahead and tweaked configure with the extra asm command in conftes2.s above. It passes, but then I get it misconfigured to ppc64, and then make does not work, as it wants to build ppc64-specific asm code. The following does it better:

$ ./configure --disable-asm-redc

with this, both make and make check work OK. This is all so far out of Sage tree. I'll attach config.log, just in case.

[I write here as a developer of GMP-ECM]

the configure error reported in comment 32 seems to be a ld problem. User "dimpase", do you manage to configure GMP successfully?

Also, which version of GMP-ECM did you use in comment 32? The svn version (see comment 24) should fix the fact that 64-bit assembly is used on 32-bit machines. If not, please report the problem upstream on ​http://ecm.gforge.inria.fr/.

Yes, I do. MPIR, to be more precise. The version on #8664.

Also, which version of GMP-ECM did you use in comment 32?

the one packed in the spkg on this ticket.

Subsequent experiments were made on the same version (without whatever patches in the spkg, however).

I then packaged the configure fix and the extra config flag into Sage spkg and am building Sage using it and the MPIR spkg on #8664. (it's not done yet, this machine is slooooow...)

The svn version (see comment 24) should fix the fact that 64-bit assembly is used on 32-bit machines. If not, please report the problem upstream on ​http://ecm.gforge.inria.fr/.

do you want me to test the svn version on this machine?

yes, as upstream developer I cannot help unless you report a problem with the (vanilla) upstream version.

Of course you are also free to solve the problem within Sage, but if it is not due to the Sage packaging, it would be useful to report it upstream.

Jeroen, can you try configuring with --disable-asm-redc?

The build (outside of Sage) works.

Well, I'm a bit unsure what to do now. I can of course include the patch, but that does not what we actually want (it's just a work-around).

Well, since the patch comes from upstream and fixes the problem is all known cases, I think it makes sense to make a new ecm spkg with this patch included. Leif, what do you think (and could you make the spkg? YES/NO)
