* Denested src folder to root, renamed testing to asmjit-testing
* Refactored how headers are included into <asmjit/...> form. This
is necessary as compilers would never simplify a path once a ..
appears in include directory - then paths such as ../core/../core
appeared in asserts, which was ugly
* Moved support utilities into asmjit/support/... (still included
by asmjit/core.h for convenience and compatibility)
* Added CMakePresets.json for making it easy to develop AsmJit
* Reworked CMakeLists to be shorter and use CMake option(),
etc... This simplifies it and makes it using more standard
features
* ASMJIT_EMBED now creates asmjit_embed INTERFACE library,
which is accessible via asmjit::asmjit target - this simplifies
embedding and makes it the same as library targets from a CMake
perspective
* Removed ASMJIT_DEPS - this is now provided by cmake target
aliases - 'asmjit::asmjit' so users should not need this variable
* Changed meaning of ASMJIT_LIBS - this now contains only AsmJit
dependencies without asmjit::asmjit target alias. Don't rely on
ASMJIT_LIBS anymore as it's only used internally
* Removed ASMJIT_NO_DEPRECATED option - AsmJit is not going
to provide controllable deprecations in the future
* Removed ASMJIT_NO_VALIDATION in favor of ASMJIT_NO_INTROSPECTION,
which now controls query, features, and validation API presence
* Removed ASMJIT_DIR option - it was never really needed
* Removed AMX_TRANSPOSE feature from instruction database (X86).
Intel has removed it as well, so it's a feature that won't
be siliconized
* Refactored the whole codebase to use snake_case convention to
name functions and variables, including member variables.
Class naming is unchanged and each starts with upper-case
character. The intention of this change is to make the source
code more readable and consistent across multiple projects
where AsmJit is currently used.
* Refactored support.h to make it more shareable across projects.
* x86::Vec now inherits from UniVec
* minor changes in JitAllocator and WriteScope in order to make
the size of WriteScope smaller
* added ZoneStatistics and Zone::statistics() getter
* improved x86::EmitHelper to use tables instead of choose() and
other mechanisms to pick between SSE and AVX instructions
* Refactored the whole codebase to use snake_case convention for
for functions names, function parameter names, struct members,
and variables
* Added a non-owning asmjit::Span<T> type and use into public API
to hide the usage of ZoneVector in CodeHolder, Builder, and
Compiler. Users now only get Span (with data and size), which
doesn't require users to know about ZoneVector
* Removed RAWorkId from RATiedReg in favor of RAWorkReg*
* Removed GEN from LiveInfo as it's not needed by CFG construction
to save memory (GEN was merged with LIVE-IN bits). The remaining
LIVE-IN, LIVE-OUT, and KILL bits are enough, however KILL bits may
be removed in the future as KILL bits are not needed after LIVE-IN
and LIVE-OUT converged
* Optimized the representation of LIVE-IN, LIVE-OUT, and KILL bits
per block. Now only registers that live across multiple basic
blocks are included here, which means that virtual registers that
only live in a single block are not included and won't be overhead
during liveness analysis. This optimization alone can make liveness
analysis 90% faster depending on the code generated (more virtual
registers that only live in a single basic block -> more gains)
* Optimized building liveness information bits per block. The new
code uses an optimized algorithm to prevent too many traversals
and uses a more optimized code for a case in which not too many
registers are used (it avoids array operations if the number of
all virtual registers within the function fits a single BitWord)
* Optimized code that computes which virtual register is only used
in a single basic block - this aims to optimize register allocator
in the future by using a designed code path for allocating regs
only used in a single basic block
* Reduced the information required for each live-span, which is used
by bin-packing. Now the struct is 8 bytes, which is good for a lot
of optimizations C++ compiler can do
* Added UniCompiler (ujit) which can be used to share code paths
between X86, X86_64, and AArch64 code generation (experimental).
