DEV ROM 16-11-20 build oddity.

A build of the TitaniumDev ROM, 2016-11-20, in a pre-existing build environment failed as follows :-

Debugger (castle.RiscOS.Sources.Programmer.Debugger)...
amu -E  rom_link ADDRESS=4229560812 LINKDIR=ADFS::Titan4.$._ROOL.ROOLlo.TitaniumDev.Install.ROOL.Titanium.Programmer COMPONENT=Debugger TARGET=Debugger
AMU: Don't know how to make 'Build:decgen.encodings.ARMv8_AArch32'
AMU: *** 'rom_link' not re-made because of errors ***

A take two in a new build environment worked but there was a delay long enough to look like a failure :-

Debugger (castle.RiscOS.Sources.Programmer.Debugger)...

Restarting tree generation with fresh cache file

There has been recent CVS activity in this area and the issue is new.

Building today’s, 2016-11-27, TitaniumDev ROM in new build environments and given this, Submit new decgen cache file; addition of ARMv8 encodings invalidated the old one. Should result in quicker build times, the cache file still gets rebuilt.

The ROM does build.

Take 2 has worked with today’s, 2016-11-28, ROM, there is now no “cache file corrupt” message in the log.

Many thanks.
