alpha

• MVP
• Better variable support
• Support for 64-bit ELF
• Support for 32-bit (protected) and 16-bit (real) modes; cr, dr, eflags and segments (cs, fs, etc.)
• Support for: SSE, SSE2, SSE3, SSSE3, SSE4_1, SSE4_2, MMX x86(-64) extensions
• Support for AVX and AVX2 extensions
• moving into beta phase (release of beta0)...

beta

betaf (beta foundation)

• Support for most of "normal" (to norm-part6) x86-64 instructions
• Transforming Mem enum into struct
• Parser support for closures () other than memory address
• Support for "modifiers" that is: base:mod1:mod2
• Support for comptime mathematical evaluations ($() closure)
• Support for constant user defined mathematical values (that aren't symbols, but inline immediates)
• Improved segmentation (allow prefixing with % and free up # prefix)
• Support for includes
• Support for label attributes (#() closure)
• Migration (from legacy *gen_ins) to new codegen API (GenAPI struct)
• Fix OSOP and ASOP prefixes (Operand/Address Size Override Prefix (for memory))
• Optimize Instruction struct

betao (beta obj)

• Variables overhaul (labels as variables)
• Switch ! prefix for keywords for .
• Relocation/Symbol overhaul (use of @() closure)
• Tests for relocations and other things
• Better target handling (ELF rewritten from zero)
• Support for custom sections (with .section keyword)

beta

• Create documentation (including better readme ;))
• Overall polish:
  • Allow for type in labels attributes.
  • Make sections also symbols.
  • Allow for use of PREFIX_VAL in ExtSymbolRef.
  • Move some of logic in src/main.rs to separate file.
  • Mem support for (R)IP (addresing like ($10))
  • Allow for different size relocations (relXX and absXX)
  • Fix in, lea, wrf/gsbase, loopXX and out instructions.
  • Add missing lgdt and lidt instructions.
  • Allow using lock, repXX mnemonics as prefix
  • Allow for using symbols/relocations in more than one place (as address or value under address; .deref/.ref directives)
  • Remove .assemble() from match statement in src/core/comp.rs:compile_instruction and move inside compile_label
  • Create .debug_assemble() (--debug)
  • Limit lifetimes, where they are unnecessary (use owned values)
  • Replace Strings with Arc<str>/Rc<str>.
  • Allow for usage of multi threads to compile labels/sections
  • Revamp AType and src/pre/chk.rs in favor of CheckAPI (like is with GenAPI)
  • Revamp errors (better readability) with explainations
  • Create src/docs/errors.md and --explain=[ECD]
• moving into beta-avx phase...

beta-avx

Goal: implement most of AVX based (E)VEX instructions

• Prepare pasm's syntax for AVX-512
• Prepare backend for AVX-512 (add IS_BCST flag to Mem, add support for masks, etc. in parser)
• implement EVEX support
• ISA implementation (divided in 15 parts):
  • avx-ext-0
  • avx-ext-1
  • avx-ext-2
  • avx-ext-3
  • avx-ext-4
  • avx-ext-5
  • avx-ext-6
  • avx-ext-7
  • avx-ext-8
  • avx-ext-9
  • avx-ext-a
  • avx-ext-b
  • avx-ext-c
  • avx-ext-d
  • avx-ext-e (vsib)
• Move to beta-intel-apx

beta-intel-apx

Goal: implement support for Intel APX

• cleanup Instruction in src/shr/ast.rs (it is barely readable) and prepare it for Intel APX
• Patch {sae} and {er} modifiers in CheckAPI (actually check if it's correct).
• implement support for APX in syntax
• implement checking for APX (in pre::chkn::CheckAPI) - partial migration to CheckAPI :D
• implement EEVEX (extended EVEX; all 3 variants without ones for ctestcc and ccmpcc) and REX2 prefixes support
• ISA implementantation (divided in 8 parts; legacy instructions included):
  • intel-apx-0 (legacy instructions without setcc)
  • intel-apx-1 (ctestcc + ccmpcc + EEVEX support for cond. test and cmp)
  • intel-apx-2 (cfcmovcc)
  • intel-apx-3 (setcc)
  • intel-apx-4 (push2/pop2)
• Move to beta-min

beta-min

Goal: support for smaller x86-64 ISA extensions (around 284 new mnemonics)

• missing x86-64 instructions
• move to rc

rc

Goal: extensive testing, polish and optimizations of assembler, less updates/commits

• Support for 16-bit addressing
• Add nobits directive for section's
• Allow for protected public function label_name:
• Allow for long jumps (jmp ptrXX:YY and jmp m16:XX)
• Move revitalization

revitalization

• move to stable

stable

• release of stable version
