[Qemu-devel] [PATCH] bswap: fix compiler warning

[Qemu-devel] [PATCH] bswap: fix compiler warning

[Alexey Kardashevskiy]

The bswap functions use memcpy but the bswap.h header itself does not seem to
include it in some configuration such as cross compiling for powerpc64
on x86_64 machine (gcc 4.6.3 from ftp.kernel.org, headers/libs from FC18/ppc64),
the example warning is below.

The patch explicitly includes string.h.

Including string.h is certainly the right thing to do, but why do you
single it out first?

I have no idea :)
I just tried to do cross compilation and hit this one. And it is not the 
only problem, I hit another one but this is against gcc or libc, have not 
discovered it yet.

Yeah, it probably shouldn't go above the config header.  Otherwise
it's the right thing.

If string.h went directly after limits.h, we'd even preserve the
alphabetic order of the system headers :-)

Yes, please - I think that would be good. You can also cc your patch
to qemu-trivial@nongnu.org, so it will be committed as a trivial patch.

[Qemu-trivial] [PATCH v2] bswap: fix compiler warning

[Alexey Kardashevskiy]

The bswap functions use memcpy but the bswap.h header itself does not seem to
include it in some configuration such as cross compiling for powerpc64
on x86_64 machine.

The patch explicitly includes string.h.

v2:
* #include statement moved to the right place
