- Reply-to: sje at cup dot hp dot com
This is a resubmission of a patch I sent out last month, I added some
documentation changes. This patch changes configure to require the use
of the gnu assembler on HP-UX (both IA64 and HPPA). Currently IA64
documents that that gnu assembler is required but does not enforce that
requirement. The change to configure.ac adds the enforcement. On HPPA
we currently say the gnu assembler is 'highly recommended'. This
changes it to a requirement and adds the enforcement of that requirement
to configure.ac. Dave Anglin has agreed that requiring the gnu
assembler on HPPA was reasonable.
OK for checkin on the main line?
Tested on HPPA and IA64 HP-UX.
