New JIT implementation
======================
This branch provides a new JIT implementation based on [IR - Lightweight
JIT Compilation Framework](https://github.com/dstogov/ir).
As opposed to the PHP 8.* JIT approach that generates native code directly from
PHP byte-code, this implementation generates intermediate representation (IR)
and delegates all lower-level tasks to the IR Framework. IR for JIT is like an
AST for compiler.
Key benefits of the new JIT implementation:
- Usage of IR opens possibilities for better optimization and register
allocation (the resulting native code is more efficient)
- PHP doesn't have to care about most low-level details (different CPUs,
calling conventions, TLS details, etc)
- it's much easier to implement support for new targets (e.g. RISCV)
- IR framework is going to be developed separately from PHP and may accept
contributions from other projects (new optimizations, improvements, bug fixes)
Disadvantages:
- JIT compilation becomes slower (this is almost invisible for tracing
JIT, but function JIT compilation of Wordpress becomes 4 times slower)
The necessary part of the IR Framework is embedded into php-src. So, the PR
doesn't introduce new dependencies.
The new JIT implementation successfully passes all CI workflows, but it's still
not mature and may cause failures. To reduce risks, this patch doesn't remove
the old JIT implementation (that is the same as PHP-8.3 JIT). It's possible
to build PHP with the old JIT by configuring with **--disable-opcache-jit-ir**.
In the future the old implementation should be removed.

===========
This is the implementation of Opcache's JIT (Just-In-Time compiler),
This converts the PHP Virtual Machine's opcodes into x64/x86 assembly,
on POSIX platforms and Windows.
It generates native code directly from PHP byte-code and information collected
by the SSA static analysis framework (a part of the opcache optimizer).
Code is usually generated separately for each PHP byte-code instruction. Only
a few combinations are considered together (e.g. compare + conditional jump).
See [the JIT RFC](https://wiki.php.net/rfc/jit) for more details.
DynAsm
------
This uses [DynAsm](https://luajit.org/dynasm.html) (developed for LuaJIT project)
for the generation of native code. It's a very lightweight and advanced tool,
but does assume good, and very low-level development knowledge of target
assembler languages. In the past we tried LLVM, but its code generation speed
was almost 100 times slower, making it prohibitively expensive to use.
[The unofficial DynASM Documentation](https://corsix.github.io/dynasm-doc/tutorial.html)
has a tutorial, reference, and instruction listing.
In x86 builds, `zend_jit_x86.dasc` gets automatically converted to `zend_jit_x86.c` by the bundled
`dynasm` during `make`.
In arm64 builds, `zend_jit_arm64.dasc` gets automatically converted to `zend_jit_arm64.c` by the bundled
`dynasm` during `make`.
This converts the PHP Virtual Machine's opcodes into Intermediate
Representation and uses [IR - Lightweight JIT Compilation Framework](https://github.com/dstogov/ir)
to produce optimized native code. The necessary part of the IR
Framework is embedded into php-src.

### Checking dasc files for in a different architecture
The following command can be run to manually check if the modified `.dasc code` is at least transpilable
for an architecture you're not using, e.g.:
For arm64: `ext/opcache/minilua ext/opcache/jit/dynasm/dynasm.lua -D ARM64=1 -o ext/opcache/jit/zend_jit_arm64.ignored.c ext/opcache/jit/zend_jit_arm64.dasc`

For i386 (i.e. 32-bit): `ext/opcache/minilua ext/opcache/jit/dynasm/dynasm.lua -o ext/opcache/jit/zend_jit_x86.ignored.c ext/opcache/jit/zend_jit_x86.dasc`

/**
* @brief JIT Profiling APIs
*
* The JIT Profiling API is used to report information about just-in-time
* generated code that can be used by performance tools. The user inserts
* calls in the code generator to report information before JIT-compiled
* code goes to execution. This information is collected at runtime and used
* by tools like Intel(R) VTune(TM) Amplifier to display performance metrics
* associated with JIT-compiled code.
*
* These APIs can be used to\n
* - **Profile trace-based and method-based JIT-compiled
* code**. Some examples of environments that you can profile with these APIs:
* dynamic JIT compilation of JavaScript code traces, JIT execution in OpenCL(TM)
* software technology, Java/.NET managed execution environments, and custom
* ISV JIT engines.
* @code
* #include <jitprofiling.h>
*
* if (iJIT_IsProfilingActive != iJIT_SAMPLING_ON) {
* return;
* }
*
* iJIT_Method_Load jmethod = {0};
* jmethod.method_id = iJIT_GetNewMethodID();
* jmethod.method_name = "method_name";
* jmethod.class_file_name = "class_name";
* jmethod.source_file_name = "source_file_name";
* jmethod.method_load_address = code_addr;
* jmethod.method_size = code_size;
*
* iJIT_NotifyEvent(iJVM_EVENT_TYPE_METHOD_LOAD_FINISHED, (void*)&jmethod);
* iJIT_NotifyEvent(iJVM_EVENT_TYPE_SHUTDOWN, NULL);
* @endcode
*
* * Expected behavior:
* * If any iJVM_EVENT_TYPE_METHOD_LOAD_FINISHED event overwrites an
* already reported method, then such a method becomes invalid and its
* memory region is treated as unloaded. VTune Amplifier displays the metrics
* collected by the method until it is overwritten.
* * If supplied line number information contains multiple source lines for
* the same assembly instruction (code location), then VTune Amplifier picks up
* the first line number.
* * Dynamically generated code can be associated with a module name.
* Use the iJIT_Method_Load_V2 structure.\n
* Clarification of some cases:
* * If you register a function with the same method ID multiple times,
* specifying different module names, then the VTune Amplifier picks up
* the module name registered first. If you want to distinguish the same
* function between different JIT engines, supply different method IDs for
* each function. Other symbolic information (for example, source file)
* can be identical.
*
* - **Analyze split functions** (multiple joint or disjoint code regions
* belonging to the same function) **including re-JIT**
* with potential overlapping of code regions in time, which is common in
* resource-limited environments.
* @code
* #include <jitprofiling.h>
*
* unsigned int method_id = iJIT_GetNewMethodID();
*
* iJIT_Method_Load a = {0};
* a.method_id = method_id;
* a.method_load_address = 0x100;
* a.method_size = 0x20;
*
* iJIT_Method_Load b = {0};
* b.method_id = method_id;
* b.method_load_address = 0x200;
* b.method_size = 0x30;
*
* iJIT_NotifyEvent(iJVM_EVENT_TYPE_METHOD_LOAD_FINISHED, (void*)&a);
* iJIT_NotifyEvent(iJVM_EVENT_TYPE_METHOD_LOAD_FINISHED, (void*)&b);
* @endcode
*
* * Expected behaviour:
* * If a iJVM_EVENT_TYPE_METHOD_LOAD_FINISHED event overwrites an
* already reported method, then such a method becomes invalid and
* its memory region is treated as unloaded.
* * All code regions reported with the same method ID are considered as
* belonging to the same method. Symbolic information (method name,
* source file name) will be taken from the first notification, and all
* subsequent notifications with the same method ID will be processed
* only for line number table information. So, the VTune Amplifier will map
* samples to a source line using the line number table from the current
* notification while taking the source file name from the very first one.\n
* Clarification of some cases:\n
* * If you register a second code region with a different source file
* name and the same method ID, then this information will be saved and
* will not be considered as an extension of the first code region, but
* VTune Amplifier will use the source file of the first code region and map
* performance metrics incorrectly.
* * If you register a second code region with the same source file as
* for the first region and the same method ID, then the source file will be
* discarded but VTune Amplifier will map metrics to the source file correctly.
* * If you register a second code region with a null source file and
* the same method ID, then provided line number info will be associated
* with the source file of the first code region.
*
* - **Explore inline functions** including multi-level hierarchy of
* nested inline methods which shows how performance metrics are distributed through them.
* @code
* #include <jitprofiling.h>
*
* // method_id parent_id
* // [-- c --] 3000 2000
* // [---- d -----] 2001 1000
* // [---- b ----] 2000 1000
* // [------------ a ----------------] 1000 n/a
*
* iJIT_Method_Load a = {0};
* a.method_id = 1000;
*
* iJIT_Method_Inline_Load b = {0};
* b.method_id = 2000;
* b.parent_method_id = 1000;
*
* iJIT_Method_Inline_Load c = {0};
* c.method_id = 3000;
* c.parent_method_id = 2000;
*
* iJIT_Method_Inline_Load d = {0};
* d.method_id = 2001;
* d.parent_method_id = 1000;
*
* iJIT_NotifyEvent(iJVM_EVENT_TYPE_METHOD_LOAD_FINISHED, (void*)&a);
* iJIT_NotifyEvent(iJVM_EVENT_TYPE_METHOD_INLINE_LOAD_FINISHED, (void*)&b);
* iJIT_NotifyEvent(iJVM_EVENT_TYPE_METHOD_INLINE_LOAD_FINISHED, (void*)&c);
* iJIT_NotifyEvent(iJVM_EVENT_TYPE_METHOD_INLINE_LOAD_FINISHED, (void*)&d);
* @endcode
*
* * Requirements:
* * Each inline (iJIT_Method_Inline_Load) method should be associated
* with two method IDs: one for itself; one for its immediate parent.
* * Address regions of inline methods of the same parent method cannot
* overlap each other.
* * Execution of the parent method must not be started until it and all
* its inline methods are reported.
* * Expected behaviour:
* * In case of nested inline methods an order of
* iJVM_EVENT_TYPE_METHOD_INLINE_LOAD_FINISHED events is not important.
* * If any event overwrites either inline method or top parent method,
* then the parent, including inline methods, becomes invalid and its memory
* region is treated as unloaded.
*
* **Life time of allocated data**\n
* The client sends an event notification to the agent with event-specific
* data, which is a structure. The pointers in the structure refer to memory
* allocated by the client, which responsible for releasing it. The pointers are
* used by the iJIT_NotifyEvent method to copy client's data in a trace file,
* and they are not used after the iJIT_NotifyEvent method returns.
