This set of patches moves global variables to tcg_ctx:
gen_opc_ptr
gen_opparam_ptr
gen_opc_buf
gen_opparam_buf

Build tested for all targets.
Execution tested on ARM.

I didn't notice any slow-down of kernel boot after this set was applied.

Changelog:
v1->v2:
Introduced TCGContext *tcg_cur_ctx global to use in those places where we don't
have an interface to pass pointer to tcg_ctx.
Code style clean-up

Evgeny (2):
  tcg/tcg.h: Duplicate global TCG variables in TCGContext
  TCG: Remove unused global variables

Evgeny Voevodin (5):
  translate-all.c: Introduce TCGContext *tcg_cur_ctx
  TCG: Use gen_opc_ptr from context instead of global variable.
  TCG: Use gen_opparam_ptr from context instead of global variable.
  TCG: Use gen_opc_buf from context instead of global variable.
  TCG: Use gen_opparam_buf from context instead of global variable.

We will use this pointer from functions where we don't have an
interface to pass tcg_ctx as a parameter.

It seems that I cherry-picked commits that were made before I correctly
set a user name. Hope I don't need to generate v3 because of that.

I don't think this is worthwhile.  It'll just make the whole thing slower,
passing around unnecessary pointers.

1. I didn't noticed any slow-down of kernel boot process. Maybe it's 
worth to make more
tests with self modifying code but I don't think so, because
2. The most intensive usage of tcg_cur_ctx is in tcg/tcg-op.h functions. 
If we look carefully at
them then we will see that there are only few functions for which single 
excessive dereferencing
of a pointer leads to any significant slow-down. These functions are 
those which make just one
or two operations and exit. And we should keep in mind that there is 
only single dereference of
a pointer since it is stored in the register for further operations.

Of course some slow-down should present but I found it negligible 
(actually I didn't find it at all).
If there are some common tests for TCG generation speed I can try to run 
them and report results.

Also we can specify tcg_cur_ctx as const and in that case I guess that 
dereferencing of tcg_cur_ctx
should not lead to any slow-down.

Also I can drop tcg_cur_ctx and use tcg_ctx.xxx instead as was in the 
first series.

What about the rest patches?

Any other comments on the patches?
I didn't get the consensus. Do we need a pointer to tcg context?
As I said before, I didn't notice any slow-down with it.

  Would you like to try to run some benchmark after the kernel booting? Like
Yeongkyoon Lee done with his qemu_ld/qemu_st work [1], EEMBC, nbench
, or even SPEC. ;)

Here are the results of tests before and after this patch series was 
applied:

* EEMBC CoreMark (before -> after)
   - Guest: Exynos4210 ARMv7, Linux (Custom buildroot image)
   - Host: Intel(R) Core(TM) i5 CPU 750 @ 2.67GHz, 4GB RAM, Linux
   - Results: 1148.105626 -> 1161.440186 (+1.16%)

* nbench (before -> after)
   - Guest: Exynos4210 ARMv7, Linux (Custom buildroot image)
   - Host: Intel(R) Core(TM) i5 CPU 750 @ 2.67GHz, 4GB RAM, Linux
   - Results
     . MEMORY INDEX: 1.864 -> 1.862 (-0.11%)
     . INTEGER INDEX: 2.518 -> 2.523 (+0.2%)
     . FLOATING-POINT INDEX: 0.385 -> 0.394 (+2.34%)


Those tests show that it became even faster :))

But I'm quite sceptical about such results.
The thing is that in case of nbench it prints the warning if results are 
not 95% statistically accurate.
So we can be sure that nbench result is 95% accurate.
And it's obvious that result shown above are in the scope of this accuracy.
I don't know the accuracy of CoreMark.

So, the main decision we can make that this patch series didn't 
introduce any slow-down comparable to inaccuracy of the measurement.

Is this enough?

Today I made more precise testing with usage of --enable-profiler.

Here is the test procedure:
1. Boot Linux Kernel 5 times.
2. For each iteration wait while "JIT cycles" is stable for ~10 seconds
3. Write down the "cycles/op"

Here are the results:

Before clean-up:
min: 731.9
max: 735.8
avg: 734.3
standard deviation: ~2 = 0.3%
Avarage cycles/op = 734 +- 2

After clean-up:
min: 747.2
max: 751.7
avg: 750.5
standard deviation: ~2 = 0.3%
Avarage cycles/op = 750 +- 2
Slow-down of TCG code generation = 2.2%


After clean-up with TCGContext *const tcg_cur_ctx:
min: 730.6
max: 733.2
avg: 728.7
standard deviation: ~2 = 0.3%
Avarage cycles/op = 729 +- 2
Slow-down of TCG code generation = 0%

I suggest to define tcg_cur_ctx as TCGContext *const.
Then we will get rid of TCG code generation slow-down and also
will have no usage of global variables.

How does this compare with the original version without pointers? I
think that version may be safer to be assumed to be optimized by the
compiler.

I did more testing with different gcc versions and different patch series:

gcc verion   v1 clean-up, no pointer       v2 clean-up, const pointer   
    master
gcc-4.4        754.3                                   752.1 
                                   769.8
gcc-4.5        770.8                                   779.8 
                                   774.8
gcc-4.6        731.8                                   729.8 
                                   737

Conclusion:
  - First clean-up series without pointer operates faster than master in 
all cases. It's probably because
    data is cached more efficiently.
  - Second clean-up series with constant pointer operates faster than 
master in the case of gcc-4.4 and gcc-4.6.
    In the case of gcc-4.5 it seems that const pointer is not optimised 
as I assumed.

I think that it's worth to generate third series without pointer and 
with code clean-up included in second.

How do you think?
