      target-arm: Drop success/fail return from cpreg read and write functions · c4241c7d
      由 Peter Maydell 提交于 
      All cpreg read and write functions now return 0, so we can clean up
their prototypes:
 * write functions return void
 * read functions return the value rather than taking a pointer
   to write the value to

This is a fairly mechanical change which makes only the bare
minimum set of changes to the callers of read and write functions.

      target-arm: Split cpreg access checks out from read/write functions · f59df3f2
      由 Peter Maydell 提交于 
      Several of the system registers handled via the ARMCPRegInfo
mechanism have access trap control bits controlling whether the
registers are accessible to lower privilege levels. Replace
the existing mechanism (allowing the read and write functions
to return EXCP_UDEF if access is denied) with a dedicated
"check access rights" function pointer in the ARMCPRegInfo.
This will allow us to simplify some of the register definitions,
which no longer need read/write functions purely to handle
the access checks.

We take the opportunity to define the return value from the
access checking function in a way that allows us to set the
correct exception syndrome information for exceptions taken
to AArch64 (which may need to distinguish access failures due
to a configurable trap or enable from other kinds of access
failure).

This commit defines the new mechanism but does not move any
of the registers across to use it.

      exec.h cleanup · 3e457172
      由 Blue Swirl 提交于 
      Move softmmu_exec.h include directives from target-*/exec.h to
target-*/op_helper.c. Move also various other stuff only used in
op_helper.c there.

Define global env in dyngen-exec.h.

For i386, move wrappers for segment and FPU helpers from user-exec.c
to op_helper.c. Implement raise_exception_err_env() to handle dynamic
CPUState. Move the function declarations to cpu.h since they can be
used outside of op_helper.c context.

LM32, s390x, UniCore32: remove unused cpu_halted(), regs_to_env() and
env_to_regs().

ARM: make raise_exception() static.

Convert
#include "exec.h"
to
#include "cpu.h"
#include "dyngen-exec.h"
and remove now unused target-*/exec.h.
