They are helpers for the ZMMReg fields, so name them accordingly.
This is just a global search+replace, no other changes are being

The struct represents a 512-bit register, so name it accordingly.
This is just a global search+replace, no other changes are being

Backports commit fa4518741ed69aa7993f9c15bb52eacc375681fc from qemu
Rename the function so that the reason for its existence is
clearer: it does x86-specific initialization of TCG structures.
Backports commit 63618b4ed48f0fc2a7a3fd1117e2f0b512248dab from qemu
Detect the clflushopt and pcommit instructions and check their
corresponding feature flags, instead of checking CPUID_SSE and
CPUID_CLFLUSH.
Backports commit 891bc821a3ee462b09b1ec436f2891f00ab1f85b from qemu
Accept the clwb instruction (66 0F AE /6) if its corresponding feature
flag is enabled on CPUID[7].
Backports commit 5e1fac2dba7780e0cb2c022d4b39586af70bea0d from qemu
Some targets already had this within their logic, but make sure
it's present for all targets.
Backports commit 522a0d4e3c0d397ffb45ec400d8cbd426dad9d17 from qemu
Reduce the boilerplate required for each target. At the same time,
move the test for breakpoint after calling tcg_gen_insn_start.
Note that arm and aarch64 do not use cpu_breakpoint_test, but still
move the inline test down after tcg_gen_insn_start.
Backports commit b933066ae03d924a92b2616b4a24e7d91cd5b841 from qemu
Left shift of negative values is undefined behavior. Detected by clang:
qemu/target-i386/translate.c:2423:26: runtime error:
left shift of negative value -8
This changes the code to reverse the sign after the left shift.
Backports commit 712b4243c761cb6ab6a4367a160fd2a42e2d4b76 from qemu
Introduce helper_get_dr so that we don't have to put CR4[DE]
into the scarce HFLAGS resource. At the same time, rename
helper_movl_drN_T0 to helper_set_dr and set the helper flags.
Backports commit d0052339236072bbf08c1d600c0906126b1ab258 from qemu
It is no longer used, so tidy up everything reached by it.
This includes the gen_opc_* arrays, the search_pc parameter
and the inline gen_intermediate_code_internal functions.
Backports commit 4e5e1215156662b2b153255c49d4640d82c5568b from qemu
The gen_opc_* arrays are already redundant with the data stored in
the insn_start arguments. Transition restore_state_to_opc to use
data from the latter.
Backports commit bad729e272387de7dbfa3ec4319036552fc6c107 from qemu
This patch fixes exception handling for memory helpers
and removes obsolete PC update from translate.c.
Backports commit 2afbdf84807d673eb682cb78158e11cdacbf4673 from qemu
This patch fixes exception handling for div instructions
and removes obsolete PC update from translate.c.
Backports commit cc33c5d66bb315f77739f761a3f868a7d138c041 from qemu
This is set to true when the index is for an instruction fetch
translation.
The core get_page_addr_code() sets it, as do the SOFTMMU_CODE_ACCESS
acessors.
All targets ignore it for now, and all other callers pass "false".
This will allow targets who wish to split the mmu index between
instruction and data accesses to do so. A subsequent patch will
do just that for PowerPC.
Backports commit 97ed5ccdee95f0b98bedc601ff979e368583472c from qemu
This patch denies crossing the boundary of the pages in the replay mode,
because it can cause an exception. Do it only when boundary is
crossed by the first instruction in the block.
If current instruction already crossed the bound - it's ok,
because an exception hasn't stopped this code.
Backports commit 5b9efc39aee90bbd343793e942bf8f582a0c9e4f from qemu
TCG generates optimized code for i386 repz instructions in single step mode.
It means that when ecx becomes 0, execution of the string instruction breaks
immediately without an additional iteration for ecx==0 (which will only check
ecx and set the flags). Omitting this iteration leads to different
instructions counting in singlestep mode and in normal execution.
This patch disables optimization of this last iteration for icount mode
which should be deterministic.
Backport commit c4d4525c38cd93cc5d1a743976eb25ac571d435f from qemu
All of the core-code usages of this API have the cpu pointer handy so
pass it in. There are only 3 architecture specific usages (2 of which
are commented out) which can just use ENV_GET_CPU() locally to get the
cpu pointer. The reduces core code usage of the CPU env, which brings
us closer to common-obj'ing these core files.
Backports commit bbd77c180d7ff1b04a7661bb878939b2e1d23798 from qemu
In order to do this, stop using the cpu_in*/out* helpers, and instead
access address_space_io directly.
cpu_in* and cpu_out* remain for usage in the monitor, in qtest, and
in Xen.
Backports commit 3f7d84648607cc0fcb3812bb4b88978e2a7aa24f from qemu
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
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
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.
Thus, use cpu_env as the parameter, not TCG_AREG0 directly.
Update all uses in the translators.
Backports commit e1ccc05444676b92c63708096e36582be27fbee1 from qemu
helper_sysenter in qemu/target-i386/seg_helper.c didn't check properly if a call interrupt callback was registred.
It has been fixed by copying the helper_syscall behavior.
