Joe Komlodi 2016a6a765 target/microblaze: Fix FPU2 instruction check
The check to see if we can use FPU2 instructions would return 0 if
cfg.use_fpu == 2, rather than returning the PVR2_USE_FPU2_MASK.

This would cause all FPU2 instructions (fsqrt, flt, fint) to not be used.

Tong Ho 7cdae31d3a target/microblaze: Add MFS Rd,EDR translation
This is to fix cpu-abort with 'qemu: fatal: unknown mfs reg d'
(in the default case) when microblaze guest issues 'MFS Rd,EDR'
instruction.

Since embeddedsw release 2019.2, XPlm_ExceptionHandler() issues
the instruction on exception, and microblaze model aborts when
PLM firmware guest encounters an exception.

Philippe Mathieu-Daudé dcb32f1d8f tcg: Search includes from the project root source directory
We currently search both the root and the tcg/ directories for tcg
files:

  $ git grep '#include "tcg/' | wc -l
  28

  $ git grep '#include "tcg[^/]' | wc -l
  94

To simplify the preprocessor search path, unify by expliciting the
tcg/ directory.

Patch created mechanically by running:

  $ for x in \
      tcg.h tcg-mo.h tcg-op.h tcg-opc.h \
      tcg-op-gvec.h tcg-gvec-desc.h; do \

      $(git grep -l "#include \"$x\""); \

Robert Foley fc59d2d870 qemu_log_lock/unlock now preserves the qemu_logfile handle.
qemu_log_lock() now returns a handle and qemu_log_unlock() receives a
handle to unlock.  This allows for changing the handle during logging
and ensures the lock() and unlock() are for the same file.

Also in target/tilegx/translate.c removed the qemu_log_lock()/unlock()
calls (and the log("\n")), since the translator can longjmp out of the
loop if it attempts to translate an instruction in an inaccessible page.

Markus Armbruster 90c84c5600 qom/cpu: Simplify how CPUClass:cpu_dump_state() prints
CPUClass method dump_statistics() takes an fprintf()-like callback and
a FILE * to pass to it.  Most callers pass fprintf() and stderr.
log_cpu_state() passes fprintf() and qemu_log_file.
hmp_info_registers() passes monitor_fprintf() and the current monitor
cast to FILE *.  monitor_fprintf() casts it right back, and is
otherwise identical to monitor_printf().

The callback gets passed around a lot, which is tiresome.  The
type-punning around monitor_fprintf() is ugly.

Drop the callback, and call qemu_fprintf() instead.  Also gets rid of
the type-punning, since qemu_fprintf() takes NULL instead of the
current monitor cast to FILE *.

Richard Henderson 1d48474d8e disas: Remove unused flags arguments
Now that every target is using the disas_set_info hook,
the flags argument is unused.  Remove it.

Richard Henderson 1c2adb958f tcg: Initialize cpu_env generically
This is identical for each target.  So, move the initialization to
common code.  Move the variable itself out of tcg_ctx and name it
cpu_env to minimize changes within targets.

This also means we can remove tcg_global_reg_new_{ptr,i32,i64},
since there are no longer global-register temps created by targets.
