This is a first patchset in removing target_ulong from non-target/
directories. As use of target_ulong is spread accross the codebase we
are attempting to target as few maintainers as possible with each
patchset in order to ease reviewing.
The following instances of target_ulong remain in accel/ and tcg/
- atomic helpers (atomic_common.c.inc), cpu_atomic_*()
(atomic_template.h,) and cpu_[st|ld]*()
(cputlb.c/ldst_common.c.inc) are only used in target/ and can
be pulled out into a separate target-specific file;
- walk_memory_regions() is used in user-exec.c and
linux-user/elfload.c;
- kvm_find_sw_breakpoint() in kvm-all.c used in target/;
Changes in v2:
- addr argument in tb_invalidate_phys_addr() changed from vaddr
to hwaddr;
- Removed previous patch:
"[PATCH 4/8] accel/tcg: Replace target_ulong with vaddr in
helper_unaligned_*()"
as these functions are removed by Richard's patches;
- First patch:
"[PATCH 1/8] accel: Replace `target_ulong` with `vaddr` in TB/TLB"
has been split into patches 1-7 to ease reviewing;
- Pulled in target/ changes to cpu_get_tb_cpu_state() into this
patchset. This was done to avoid pointer casts to target_ulong *
which would break for 32-bit targets on a 64-bit BE host;
Note the small target/ changes are collected in a single
patch to not break bisection. If it's still desirable to split
based on maintainer, let me know;
- `last` argument of pageflags_[find|next] changed from target_long
to vaddr. This change was left out of the last patchset due to
triggering a "Bad ram pointer" error (softmmu/physmem.c:2273)
when running make check for a i386-softmmu target.
I was not able to recreate this on master or post rebase on
Richard's tcg-once branch.
Changes in v3:
- Rebased on master
Finally, the grand goal is to allow for heterogeneous QEMU binaries
consisting of multiple frontends.
