gcc 11.1.0 mpfr

gcc 11.1.0 mpfr

[Guy Harrison]

Hi,

(was advised to post here rather than gcc-help@)

$ egrep "mpfr\.h" log/cfg/cfg.gcc-11.1.0.log 
checking for the correct version of mpfr.h... buggy but acceptable

It appears "gcc-11.1.0/contrib/download_prerequisites"  
specifies "mpfr-3.1.4.tar.bz2" whereas top level 'configure' 
has "MPFR_VERSION_NUM(3,1,6)".

Is there a reason mpfr 3.1.6 isn't being used?

TIA

No good reason: that script was not updated with new versions. GCC-11 is
also known to work fine with the most recent mpfr version 4.1.0.

Yes, the update of the minimum version and the buggy check was
done by Janne w/o adjusting the download script.

Should I adjust download_prerequisites accordingly?

It looks like the adjustment was made but the file was not added uploaded:
[apinski@xeond2 gcc]$ ./contrib/download_prerequisites

Yes, indeed, and please do not forget to update also the hashes
in contrib/prerequisites.md5 and contrib/prerequisites.sha512 .

However, I wonder why we change only the default mpfr version to latest
available version but keep gmp and mpc versions from 2015?


Thanks
Bernd.

I've reverted the change and instead upped to 3.1.6 as I intended to suggest
to avoid printing the offending warning on configure time.  This can be picked
by branches that are similarly affected.

Any discussion on upping versions further needs to be accompanied by
actual testing on target/host combos where it's usually used (non-Linux).
