[abi] AsmJit v1.17 - cumulative & breaking changes

Browse Source

* Reworked register operands - all vector registers are now
    platform::Vec deriving from UniVec (universal vector operand),
    additionally, there is no platform::Reg, instead asmjit::Reg
    provides all necessary features to make it a base register for
    each target architecture
  * Reworked casting between registers - now architecture agnostic
    names are preferred - use Gp32 instead of Gpd or GpW, Gp64
    instead of Gpq and GpX, etc...
  * Reworked vector registers and their names - architecture
    agnostic naming is now preferred Vec32, Vec64, Vec128, etc...
  * Reworked naming conventions used across AsmJit - for clarity
    Identifiers are now prefixed with the type, like sectionId(),
    labelId(), etc...
  * Reworked how Zone and ZoneAllocator are used across AsmJit,
    prefering Zone in most cases and ZoneAllocator only for
    containers - this change alone achieves around 5% better
    performance of Builder and Compiler
  * Reworked LabelEntry - decreased the size of the base entry
    to 16 bytes for anonymous and unnamed labels. Avoided an
    indirection when using labelEntries() - LabelEntry is now
    a value and not a pointer
  * Renamed LabelLink to Fixup
  * Added a new header <asmjit/host.h> which would include
    <asmjit/core.h> + target tools for the host architecture,
    if enabled and supported
  * Added new AArch64 instructions (BTI, CSSC, CHKFEAT)
  * Added a mvn_ alternative of mvn instruction (fix for Windows
    ARM64 SDK)
  * Added more AArch64 CPU features to CpuInfo
  * Added better support for Apple CPU detection (Apple M3, M4)
  * Added a new benchmarking tool asmjit_bench_overhead, which
    benchmarks the overhead of CodeHolder::init()/reset() and
    creating/attaching emitters to it. Thanks to the benchmark the
    most common code-paths were optimized
  * Added a new benchmarking tool asmjit_bench_regalloc, which
    aims to benchmark the cost and complexity of register allocation.
  * Renamed asmjit_test_perf to asmjit_bench_codegen to make it
    clear what is a test and what is a benchmark
