gmp 5.0.1 and gcc 4.5?

gmp 5.0.1 and gcc 4.5?

[Jack Howarth]

   I've not seen any discussion of testing gcc trunk
against the newer gmp 5.0 or 5.0.1 releases. Has anyone
done significant testing with the newer gmp releases
and are there any long term plans for bumping the
required gmp (assuming that any of the new features
or fixes are useful for gcc)? Thanks in advance for
any comments. I planning a gcc45 fink package once
gcc 4.5.0 is released and was considering whether
it made sense to try to depend on the newer gmp.

GMP is mainly used via MPFR.  Thus, I'd expect the required version to be 
bumped if a new MPFR version was required that in turn required newer GMP, 
but otherwise there would be little use to a bump.  New MPFR would be 
required if needed for folding some function of use to GCC to fold 
(erfc_scaled has been mentioned as one it would be useful to the Fortran 
front end to have MPFR support for, for example, but SVN MPFR doesn't yet 
support it; if it gains support, that might justify a future increase in 
the required MPFR version).

FYI, if someone is interested, anyone can contribute:

  http://www.mpfr.org/contrib.html

Otherwise, I fear that the implementation of most functions will not
happen before several years.

I use gcc 4.4.4 and 4.5.0 with gmp 5.0.1. I compile and use PostgreSQL
and other stuff, and have not noticed any misbehavior related to gmp or
mpfr. Although, I cannot say that I use gcc in a way that makes a lot
of gmp or mpfr testing.

The Arch Linux toolchain was built with gmp-5.0.1 about two weeks ago 
and all software linking to gmp-4 was rebuilt with gmp-5.  We have seen 
no gmp-5 related issues so far.
