While preparing to argue persuasively that the conflict check was as
simple as it could reasonably be, I discovered that this was in fact
totally wrong. It's now (I hope) a lot clearer, and probably even
more efficient.
The following changes since commit b8dc9182ed8959ce5a6aa285c3c7f78df2432ac3:
Richard Purdie (1):
qt-4.8.1: Fix compile failures on qemux86
are available in the git repository at:
git://git.yoctoproject.org/poky-contrib seebs/toolchains
http://git.yoctoproject.org/cgit.cgi/poky-contrib/log/?h=seebs/toolchains
Peter Seebach (2):
tune-sh4.inc: Fix spelling of big-endian feature set

The TUNEVALID and TUNECONFLICT/TUNECONFLICTS settings were not implemented, and there were some loose ends (like not knowing how the conflict one was spelled). Listed one or two missing features in TUNEVALID, also (in a previous patch) fixed the references to features which didn't exist. This patch also provides a whitelisting mechanism (which is completely unused) to allow vendors providing prebuilt toolchain components to restrict tunings to those based on or compatible with a particular ABI.

I'm left wondering what TUNEABI is too... The big reason I'd advocate for having it in the base stuff is that otherwise, all the OSVs are going to do their own and do it incompatibly. The one thing worse than having one incomprehensible thing is having many incomprehensible things with subtly different semantics. > > + bb.warn("Got an unexpected '%s' in MULTILIBS." % > > pairs[0]) > Shouldn't this get added to the errors list? Good question! I was unable to find anything definite on the topic. My thought is, if everything has to be multilib:, there's no reason for the leading multilib: because it adds no information, so presumably there logically *could* be something else, but I haven't seen any and don't know about them. > > + else: > > + if pairs[1] == 'lib': > > + tune_error_set.append("The multilib 'lib' was > > specified, but that causes parse errors.") > Hmm, it does? Yeah, that was the thing I ran into when I tried a default config someone suggested; I thoughtfully corrected lib32 to lib, and libxcb exploded with two pages of Python stack traces and diagnostics. If that's not intentional, I can drop this check and we can treat it as a package bug. > What we really want to check here is that each pair[1] value is > unique. > Again, I'd just add this to the error list.

Ah, I see what's happened here. This variable is used to append to BBCLASSEXTEND where there are other values like "nativesdk" and "native". Looking at the code, I think you should process MULTILIB_VARIANTS. The naming of the various multilib variables could probably do with improvement in places :/. Another good sanity check might be to look at the BBCLASSEXTEND values and ensure they're in the list "native", "nativesdk", "multilib:xxx", "cross". > > > + else: > > > + if pairs[1] == 'lib': > > > + tune_error_set.append("The multilib 'lib' was > > > specified, but that causes parse errors.") > > > Hmm, it does? > > Yeah, that was the thing I ran into when I tried a default config > someone suggested; I thoughtfully corrected lib32 to lib, and libxcb > exploded with two pages of Python stack traces and diagnostics.

Adding that as a separate commit. > I think its a packaging bug. I'd be interested to see the error. I'll try to get it to show. I'm still getting the x86_64x86_64 thing first. :) Should have cleaned up versions of this "soon". -s -- Listen, get this.
