[Qemu-devel] [PATCH] target-ppc: Fix compilation error with --enable-debug

[Peter Maydell]

The PPC helper functions booke206_tlbflush and booke_setpid both
take an i32 argument, so we need to use TCGv_i32 rather than TCGv,
to avoid a compilation failure when compiling in debug mode.

See http://patchwork.ozlabs.org/patch/96665/

It's a waste of time if build fixes take more than 3 days to get committed.

The typical process - several days until the maintainer accepts it, more
days until there is a pull request, even more days until it is pulled -
is good enough for new features, but too slow for bug fixes, especially
when they fix broken builds.

Cheers,
Stefan W.

Oops; I did try searching my mail for a fix, but obviously failed
to use the right search term.

I agree, but I think the solution to the problem is to not break builds. I'm currently spending all day setting up kvm-autotest for automated regression testing and am eagerly waiting on Stefan to get the buildbot stuff rolling on submaintainer trees.

With those two things in place, we should be a lot safer.
