* 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
mach_vm_remap() allows to create a dual mapping without having to
use a file descriptor, which has to open a file or shm memory. The
problem is that the recent macos version started displaying a popup
message when such file is opened and that annoyed a lot of users.
Thus, the initial code-path is no longer used, and mach_vm_remap()
is used instead.
This change only applies for x86 macs. Apple silicon doesn't allow
dual mapping and instead uses MAP_JIT.
* Renamed all eq() methods to equals() (consistency) (ABI)
* Reorganized some X86 instructions in X86 database
* Properly detect RISC-V CPU at compile time (Environment)
* Removed CallConvId::kNone in favor of defaulting to kCDecl (ABI)
* CallConvId::kHost is now alias to CallConvId::kCDecl (ABI)
* Added FloatABI to Environment to disginguish between softfloat
and hardfloat
* Added more AArch64 CPU features and their detection (ABI)
* Because of CallConvId changes it's now possible to run
compiler tests on 32-bit ARM (fixes a bug in test cases)
* Added QEMU to CI build matrix to test different architectures
* Added more clang compilers on CI (CI)
* Added memory sanitizer to build matrix (CI)
* Use problem matcher in all builds (CI)
* Fixed the use of some constructs in tests
* Fixed warnings about unused functions in tests
* Fixed warnings about unused variables caused by some build options
* Fixed tests to be clean with MSAN (zeroing memory filled by JIT code)
* Removed -Wclass-memaccess (gcc) from ignored warnings
* Removed -Wconstant-logical-operand (clang) from ignored warnings
* Removed -Wunnamed-type-template-args (clang) from ignored warnings
* Reworked InstData and InstExData to not cause UB (ABI break)
Unfortunately the existing InstData and InstExData was not good for static
analysis and in general compilers emitted warnings regarding accessing
InstNode::_opArray. The reason was that InstExNode added one or two
more operands which extended InstData::_opArray, but there was no way to
tell the C++ compiler about this layout.
It has been changed to InstNode having no operands and InstNodeWithOperands
being templatized for the right number of operands. Nodes that need to
inherit InstNode would just inherit InstNodeWithOperands<N>. It works the
same way as before, just the class hierarchy changed a little.
* Refactored workflows to use a single workflow for both VM and non-VM builds
* Compiler tests are now able to test compilation of different architectures
[ABI] Added ABI version as an inline namespace, which forms asmjit::_abi_MAJOR_MINOR
[ABI] Added support for AVX512_FP16, 16-bit broadcast, and AVX512_FP16 tests
[ABI] Added initial support for consecutive registers into instruction database and register allocator
[ABI] Added a possibility to use temporary memory in CodeHolder's zone
[ABI] Compiler::setArg() is now deprecated, use FuncNode::setArg()
[Bug] Fixed correct RW information of instructions that only support implicit zeroing with {k}
[Bug] Fixed broadcast to be able to broadcast bcst16 operands
