tcg/optimize: Handle or r,a,a with constant a 
Backports commit 2374c4b8375072da1f401c6daccc68ae76c73e63 from qemu
 2018-02-09 14:56:12 -05:00

tcg: Complete handling of ALWAYS and NEVER 
Missing from movcond, and brcondi_i32 (but not brcondi_i64).

tcg: Use tcg_malloc to allocate TCGLabel 
Pre-allocating 512 of them per TB is a waste.

Backports commit 51e3972c41598adc91fe3f4767057f5198dcc15c from qemu

tcg: Change generator-side labels to a pointer 
This is less about improved type checking than enabling a
subsequent change to the representation of labels.

Backports commit bec1631100323fac0900aea71043d5c4e22fc2fa from qemu
 2018-02-09 14:40:59 -05:00

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.

Backports commit 42a268c241183877192c376d03bd9b6d527407c7 from qemu

Richard Henderson 255a160c66
tcg: Remove unused opcodes 
We no longer need INDEX_op_end to terminate the list, nor do we
need 5 forms of nop, since we just remove the TCGOp instead.

Backports commit 15fc7daa770764cc795158cbb525569f156f3659 from qemu
 2018-02-09 13:20:41 -05:00
Richard Henderson 70f28c8bd5
tcg: Implement insert_op_before 
Rather reserving space in the op stream for optimization,
let the optimizer add ops as necessary.

Backports commit a4ce099a7a4b4734c372f6bf28f3362e370f23c1 from qemu
 2018-02-09 13:11:50 -05:00
Richard Henderson 4fcaabf38c
tcg: Remove opcodes instead of noping them out 
With the linked list scheme we need not leave nops in the stream
that we need to process later.

Backports commit 0c627cdca20155753a536c51385abb73941a59a0 from qemu
 2018-02-09 13:03:58 -05:00
Lioncash 0273e6ae18
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.
 2018-02-09 12:54:05 -05:00
Richard Henderson a41b9acc0c
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: Move emit of INDEX_op_end into gen_tb_end

tcg: Reduce ifdefs in tcg-op.c 
Almost completely eliminates the ifdefs in this file, improving
confidence in the lesser used 32-bit builds.

 2018-02-09 08:35:52 -05:00

tcg: Move some opcode generation functions out of line 
Some of these functions are really quite large.  We have a number of
things that ought to be circularly dependent, but we duplicated code
to break that chain for the inlines.

This saved 25% of the code size of one of the translators I examined.

tcg: Change ts->mem_reg to ts->mem_base 
Chain the temporaries together via pointers intstead of indices.
The mem_reg value is now mem_base->reg.  This will be important later.

This does require that the frame pointer have a global temporary
allocated for it.  This is simple bar the existing reserved_regs check.

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.
