[PATCH 0/4] tests/qtest: Introduce qtest_get_base_arch() and qtest_get_arch_bits()

[Philippe Mathieu-Daudé]

When unifying some 32/64 architectures as a single binary
(for example i386 & x86_64 -> x86), some qtests fail because
we lose some information (the arch bits).

This series introduce the tuple qtest_get_base_arch() /
qtest_get_arch_bits() to allow the tests to keep passing.

Eventually we should remove qtest_get_arch() entirely
and rename qtest_get_base_arch() -> qtest_get_arch().

So far these changes are sufficient to keep me progressing,
so posting up to this point.

[PATCH 3/4] tests/libqtest: Introduce qtest_get_base_arch()

[Philippe Mathieu-Daudé]

While qtest_get_arch() returns the target architecture name,
such "i386" or "x86_64", qtest_get_base_arch() return the
"base" (or real underlying) architecture, in this example
that is "x86".

Just a matter of taste, but I prefer g_str_equal(), that's easier to read.

Since this function might get called multiple times, would it make sense to 
cache the value? I.e.:

   static const unsigned bits;

   if (!bits) {
       ... do all the magic to find out the right bits ...
   }

   return bits;

?

... this change looks more cumbersome now (doing two checks now instead of 
one), at least at the current point in time. Do you urgently need this for 
your refactoring? If not, I'd maybe postpone such changes that make the 
checks more compilcated to a later point in time.

I wanted to replace qtest_get_arch() completely, but not that simple :(
