target-arm: Recognize UXTB, UXTH, LSR, LSL
These are all special case aliases of UBFM.

Backports commit 9924e85829fe21b5f38a5d267c9aea44c5d478ac from qemu
2018-02-11 01:34:11 -05:00

target-arm: Recognize SXTB, SXTH, SXTW, ASR
These are all special case aliases of SBFM.

Richard Henderson 53bd2b1d5c
target-arm: Implement ccmp branchless
This can allow much of a ccmp to be elided when particular
flags are subsequently dead.

Backports commit 7dd03d773e0dafae9271318fc8d6b2b14de74403 from qemu
2018-02-11 01:25:51 -05:00

target-arm: Use setcond and movcond for csel
Backports commit 259cb68491ab36427e7e5d820fe543d53b006ec6 from qemu

target-arm: Handle always condition codes within arm_test_cc
Handling this with TCG_COND_ALWAYS will allow these unlikely
cases to be handled without special cases in the rest of the
translator. The TCG optimizer ought to be able to reduce
these ALWAYS conditions completely.

Backports commit 9305eac09e61d857c9cc11e20db754dfc25a82db from qemu
2018-02-10 23:48:10 -05:00
Lioncash 94f1227f7a
target-arm: Introduce DisasCompare
Split arm_gen_test_cc into 3 functions, so that it can be reused
for non-branch TCG comparisons.

Backports commit 6c2c63d3a02c79e9035ca0370cc549d0f938a4dd from qemu
2018-02-10 23:45:47 -05:00

tcg: Remove tcg_gen_trunc_i64_i32
Replacing it with tcg_gen_extrl_i64_i32.

Backports commit ecc7b3aa71f5fdcf9ee87e74ca811d988282641d from qemu

Richard Henderson ac713c7034
tcg: Push merged memop+mmu_idx parameter to softmmu routines
The extra information is not yet used but it is now available.
This requires minor changes through all of the tcg backends.

Backports commit 3972ef6f830d65e9bacbd31257abedc055fd6dc8 from qemu

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.

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: 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.

Elton G 47150b6df3 reg_read and reg_write now work with registers W0 through W30 in Aarch64 (#716)
* reg_read and reg_write now work with registers W0 through W30 in Aarch64 emulaton

* Added a regress test for the ARM64 reg_read and reg_write on 32-bit registers (W0-W30)
Added a new macro in uc_priv.h (WRITE_DWORD_TO_QWORD), in order to write to the lower 32 bits of a 64 bit value without overwriting the whole value when using reg_write

* Fixed WRITE_DWORD macro

reg_write would zero out the high order bits when writing to 32 bit registers

e.g. uc.reg_write(UC_X86_REG_EAX, 0) would also set register RAX to zero
