Hi Christophe,
Hmm, I'm not so sure I like this very much. I think it's important for these tests to fail when an arch tries to hook up the function to the vDSO, but it's still not exported for some reason. This also regresses the ARCH=x86_64 vs ARCH=x86 thing, which SRCARCH fixes.
What about, instead, something like below, replacing the other commit?
I need to look at it in more details and perfom a test, but after first look I can't figure out how it would work.
When I build selftests,
to build 32 bits selftests I do:
make ARCH=powerpc CROSS_COMPILE=ppc-linux-
to build a 64 bits BE selftests I do:
make ARCH=powerpc CROSS_COMPILE=powerpc64-linux-
to build a 64 bits LE selftests I do:
make ARCH=powerpc CROSS_COMPILE=powerpc64le-linux-
I addition, in case someone does the build on a native platform directly,
On 32 bits, uname -m returns 'ppc' On 64 bits, uname -m returns 'ppc64' On 64 bits little endian, uname -m returns 'ppc64le'
How would this fit in the logic where IIUC you just remove '_64' from 'x86_64' to get 'x86'
Huh? That's not what tools/scripts/Makefile.arch does.
