target-*: Increment num_insns immediately after tcg_gen_insn_start 
This does tidy the icount test common to all targets.

Backports commit 959082fc4a93a016a6b697e1e0c2b373d8a3a373 from qemu
 2018-02-11 12:46:30 -05:00

target-*: Unconditionally emit tcg_gen_insn_start 
While we're at it, emit the opcode adjacent to where we currently
record data for search_pc. This puts gen_io_start et al on the
"correct" side of the marker.

Backports commit 667b8e29c5b1d8c5b4e6ad5f780ca60914eb6e96 from qemu

tcg: Rename debug_insn_start to insn_start 
With an eye toward making it mandatory.

target-i386: Make check_hw_breakpoints static 
The function is now only used from within a single file.

tcg: Change translator-side labels to a pointer 
This is improved type checking for the translators -- it's no longer
possible to accidentally swap arguments to the branch functions.

Note that the code generating backends still manipulate labels as int.

With notable exceptions, the scope of the change is just a few lines
for each target, so it's not worth building extra machinery to do this
change in per-target increments.

tcg: Put opcodes in a linked list 
The previous setup required ops and args to be completely sequential,
and was error prone when it came to both iteration and optimization.

tcg: Introduce tcg_op_buf_count and tcg_op_buf_full 
The method by which we count the number of ops emitted
is going to change. Abstract that away into some inlines.

Backports commit fe700adb3db5b028b504423b946d4ee5200a8f2f from qemu.

tcg: Change tcg_global_mem_new_* to take a TCGv_ptr 
Thus, use cpu_env as the parameter, not TCG_AREG0 directly.
Update all uses in the translators.

Ahmed Samy 02e6c14e12 x86: add MSR API via reg API (#755) 
Writing / reading to model specific registers should be as easy as
calling a function, it's a bit stupid to write shell code and run them
just to write/read to a MSR, and even worse, you need more than just a
shellcode to read...

So, add a special register ID called UC_X86_REG_MSR, which should be
passed to uc_reg_write()/uc_reg_read() as the register ID, and then a
data structure which is uc_x86_msr (12 bytes), as the value (always), where:
	Byte	Value		Size
	0	MSR ID		4
	4       MSR val		8
