[PATCH v2 0/1] Resync siteinfo.bbclass with oe.dev

[PATCH v2 0/1] Resync siteinfo.bbclass with oe.dev

[Tom Rini]

Hey all,

This is the second of two pull requests.  This doesn't depend on the first
request, it's just splitting changes up.  There's three changes here.  First,
site/ix86-common was setting the wrong value for unsigned int.  Second,
change perl to use SITEINFO variables rather than functions.  
We're down to one change now to re-sync siteinfo.bbclass with oe-core
and oe.dev.  This re-works the functions a bit inside siteinfo.bbclass
to be easier to add new platforms (and hopefully multilibs) to.

My next step is to work on merging and verifying as much as possible
the site files in oe-core and oe.dev.

v2: Rework based on Richard's comments to not be a generator and just
return a string list again.

The following changes since commit 0d03800caffc2341b74190d38f7a372223c89f4c:

[PATCH v2 1/1] siteinfo.bbclass: Port over oe.dev logic for site files

[Tom Rini]

In oe.dev we have a sets to pick out hostos/hostarch/etc site
files out of and include things like a common-linux site file.
This should also help out with adding multilib-specific site files
(ie x32).  In oe.dev we have an iterator but at Richard's request
we continue to return a list of files in siteinfo_get_files().

Not that it has been merged, can the siteinfo from meta-oe get deleted?

The class? yes.  It wasn't being used anyhow :)

Assigning SITEINFO_ENDIANESS in this way seems to break build of cross
packages (binutils, gcc).  E.g. for xscale (--> armv5te), these packages
will be build for armv5teb. This happens because tune-xscale.inc uses an
(unsafe)

| BASE_PACKAGE_ARCH = "${@['armv5teb', 'armv5te'][bb.data.getVar('SITEINFO_ENDIANESS', d, 1) == 'le']}"

statement. As there seems that something wents wrong when setting
SITEINFO_ENDIANESS in an anonymous python function, 'armv5teb' will be
assumed.

Using a more safe construct like

| BASE_PACKAGE_ARCH = "${@{'le' : 'armv5te', 'be' : 'armv5teb'}[ \
|                        bb.data.getVar('SITEINFO_ENDIANESS', d, 1)]}"

reveals that SITEINFO_ENDIANESS is undefined when expression is evaluated.

I am using bitbake master (5c8eeefc79455f058dda8f04cf4c12dc5418e00f).

since siteinfo determines endianness based on HOST_OS this will always
be wrong for cross packages to use endianness information since it will
give back the endianness of the host system but we want the endianness
of the target system. This particularly is a problem for builds where
host != target since we are trying to use this information to construct
PACKAGE_ARCH for the cross recipes which is target dependent.

So either we need to break this link in cross.bbclass and set
BASE_PACKAGE_ARCH and PACKAGE_ARCH appropriately there.

I hope the ongoing tune file overhaul addresses this issue.
