[Qemu-devel] [PATCH 0/6] Enable building and running tcg tests on i386

[Qemu-devel] [PATCH 0/6] Enable building and running tcg tests on i386

[Cleber Rosa]

The primary motivation of this patch series is to get "make -C
tests/tcg", on i386, to run.  Having all of the individual i386 tcg
tests passing is beyond the scope of this patch series, though.

The secondary motivation is to gather feedback on the status of the
tcg tests.  If you have strong opinions about it, be that they need to
be nourished and cared for, that they should be eliminated completely,
or anything in between, I'd love to hear about it.

[Qemu-devel] [PATCH 1/6] tests/tcg/test_path.c: include utils/bufferiszero.c

[Cleber Rosa]

Which contains one specific function used by iov.c.

Without this, "make -C tests/tcg test_path" (and consequently
"make -C tests/tcg" or simply "make test") fails quite early.

[Qemu-devel] [PATCH 2/6] tests/tcg/linux-test.c: remove unused include of "qemu/cutils.h"

[Cleber Rosa]

Building tests/tcg/linux-test is not currently possible because
$(QEMU_INCLUDES) is not being passed to $(CC_I386).  But, since
it's not really used, instead of adding the $(QEMU_INCLUDES),
let's remove the "qemu/ctuils.h" include instead.

getrusage() I presume, don't know if worth adding in commit message.

This fixes the build, however why not take this opportunity to fix it 
through the Makefile instead of including .c?

Phil.

Do you mean for all of the .c includes?  I just took a baby step, which
seemed more consistent with the mission (get it to build), without
changing a lot.
