[Qemu-devel] [PATCH v2 0/5] configure: TARGET_ARCH cleanups

[Qemu-devel] [PATCH v2 0/5] configure: TARGET_ARCH cleanups

[Paolo Bonzini]

We have three variables currently in config-target.h:

- TARGET_ARCH is used to create a unique per-arch symbol, used in #ifdefs.
  It is also used as a string through config-target.h, but this is almost
  always wrong.

- TARGET_ARCH2 is the name of the executable (minus the qemu-/qemu-system-
  prefix); it is not available in config-target.h.

- TARGET_TYPE is an enum but is otherwise the same as TARGET_ARCH2

This series changes all uses of TARGET_ARCH to refer to TARGET_ARCH2
instead (which is renamed to TARGET_NAME).  The TARGET_ARCH #define
is dropped, only the per-arch symbol remains.  TARGET_TYPE is then also
removed since it is serialized to the same string if TARGET_NAME is
used directly.

I included Alon's patch because of a nasty semantic conflict between it
and patch "build: do not use TARGET_ARCH".

Alon Levy (1):
  Add a stp file for usage from build directory

Paolo Bonzini (4):
  build: rename TARGET_ARCH2 to TARGET_NAME
  build: do not use TARGET_ARCH
  main: use TARGET_ARCH only for the target-specific #define
  build: drop TARGET_TYPE

[Qemu-devel] [PATCH v2 1/5] Add a stp file for usage from build directory

[Paolo Bonzini]

From: Alon Levy <alevy@redhat.com>

For systemtap the location of the process being tapped is crucial, as a
result the existing stp file requires installation for use.

There are now two files:
$(TARGET_DIR)/$(QEMU_PROG).stp-installed: copied to $(tapdir)/$(QEMU_PROG).stp
$(TARGET_DIR)/$(QEMU_PROG).stp: pointing to the built binary, usable
                                without installation

To use:
stap -I $(TARGET_DIR) ...

[Qemu-devel] [PATCH v2 3/5] build: do not use TARGET_ARCH

[Paolo Bonzini]

TARGET_ARCH is generally wrong to use, there are better variables
provided in config-target.mak.  The right one is usually TARGET_NAME
(previously TARGET_ARCH2), but for bsd-user we can also use TARGET_ABI_DIR
for consistency with linux-user.

[Qemu-devel] [PATCH v2 4/5] main: use TARGET_ARCH only for the target-specific #define

[Paolo Bonzini]

Everything else needs to match the executable name, which is
TARGET_NAME.

Before:
    $ sh4eb-linux-user/qemu-sh4eb --help
    usage: qemu-sh4 [options] program [arguments...]
    Linux CPU emulator (compiled for sh4 emulation)

After:
    $ sh4eb-linux-user/qemu-sh4eb --help
    usage: qemu-sh4eb [options] program [arguments...]
    Linux CPU emulator (compiled for sh4eb emulation)
