The Capstone disassembler has its own big-endian fixup.
Doing this twice does not work, of course. Move our current
fixup from target/arm/cpu.c to disas/arm.c.
This makes read_memory_inner_func unused and can be removed.

Now that every target is using the disas_set_info hook,
the flags argument is unused. Remove it.

If configured, prefer this over our rather dated copy of the
GPLv2-only binutils. This will be especially apparent with
the proposed vector extensions to TCG, as disas/i386.c does
not handle AVX.

Even though there is only one monitor, and thus no race on this
global data object, there is also no point in having it. We can
just as well record the decision in the read_memory_function that
we select.

Do not require the submodule, but use it if present. Allow the
command-line to override system or git submodule either way.

Hi. This failed to build for Windows:
make[1]: *** No rule to make target
'/home/petmay01/linaro/qemu-for-merges/build/w32-new/capstone/libcapstone.a'.
Stop.
Makefile:399: recipe for target 'subdir-capstone' failed
FreeBSD ar also prints a warning:
AR libcapstone.a
ar: warning: creating /root/qemu/build/all/capstone/libcapstone.a
though the build otherwise succeeds. Is it possible to silence this?
(Otherwise it shows up in my build output scripts; I could silence it
there but it would be neater if it just wasn't emitted.)
thanks

That's bad, because it suggests that bisection is going to break
across this merge commit.
Dan, is this going to be a generic problem with the new submodule
stuff, or is it specific to something with how the capstone
submodule is being handled in this patchset?

If you make your checkout go back in time to before the submodule
existed, git won't delete your checked out submodule - in case you
have commits there you still care about. So it'll print that warning
about unable to 'rmdir'. This should be harmless to the build process
in general though.
I'm not sure what's giving you the 'pathspec' message though ? I would
expect anything to ignore the capstone dir - its just like any other
untracked file once you go back in time before it was committed.
Regards,
Daniel

Sorry, just realized that was the output of my filtering of the
log. Here's what I should have quoted:

It looks like the git update script thinks that there ought to
be a 'capstone' submodule, which of course there isn't any more,
so it barfs trying to update it.

Looks like we need to make git-submodule-update depend on config-host.mak, so
that we have already re-run configure, so that vanishing modules will have been
de-selected.
Forcing a configure re-run by hand would have masked this problem. I think all
of the testing that I have been doing has been builds from empty build directories.

Yeah, ok that makes more sense. The 'config-host.mak' rules have the
list of desired submodules and those correspond to the state when you
ran configure with the patches applied.
Do we really expect make/configure todo the right thing when going
backwards in time ? I've always assumed that if you go back in time
when you need to do a 'git clean -f -x d' and re-run configure from
scratch. Certainly in the past various makefile changes in QEMU would
break, or silently not correctly recompile stuff when going backwards
in time.
Regards,
Daniel

"Yes"? Ideally at least :)

I certainly don't do that and would rather not have to think about it.
I also don't think about calling it when bisecting, however looking at
the man page, this is somehow suggested in the example:
· Automatically bisect with temporary modifications (hot-fix):
[...]
# undo the tweak to allow clean flipping to the next commit
git reset --hard
This could be a warning displayed via a post-checkout hook, for this
particular merge hash, or if you go way too back in time...

Travis is already taking too long, but we could add a such test
(merge/build/checkout backward/configure/quick build), not sure if we
gain much.

Yes. Occasionally we accidentally break this, as you note, and then
git bisection across that kind of boundary requires a painful build
from clean. But almost always bisection (across small spans of history)
works without having to do that, as do things like "check out this
branch I was working on a month ago and do a build without bothering
to clean first".
In this case you broke my standard workflow for rolling back from
an attempted merge that didn't actually build, which IME is a pretty
rare thing to have go wrong.
thanks

Ug. Ok, capstone is forcing the use of .lib for windows.

Feh. Capstone has no ARFLAGS variable. So, no, I can't fix this without
actually modifying the sub-makefile.

I think (but haven't bisected) that this series is now making 'make' noisy:
$ make -j3 qemu-nbd
make[1]: '/home/eblake/qemu-tmp/capstone/libcapstone.a' is up to date.
make: 'qemu-nbd' is up to date.
Can we figure out how to shut up make when libcapstone.a has nothing needed?
