- fixed a bug which caused a segmentation fault when writing to a file via the -P switch

• added four encodings for {vmovdqu, vmovupd} xmmN {xmmN,m/128}
  and two for {vmovdqu, vmovupd} m/128, xmmN

• added encoding for movq mv
• added support for rdpmc

- added support for push instruction with M and I operand encoding

- implemented thread safe design for global variables

- fixed missing SIB byte for jmp instruction 

- fixed a bug which can lead to SIGSEGV's on certain systems using
  `strtok_r`. (Thanks to @hugsy for pointing that out)

  it too small and assemblyline is compiled for non-Linux systems

- CI: Using GitHub Actions to validate Code Formatting

- CI: Using GitHub Actions to build and run checks

- Repo: Introducing badges to show current stats for the repository

- Tests: run.c now checks for cpu-flags to run the code. (Sometimes it
  fails because of missing CPU capabilities on GHActions)

- added support for neg: Two's Complement Negation

- fixed a bug where shift and rotate instruction produce the wrong opcode 
  when immediate is zero 

- fixed a bug when using sib addressing with no base and a single operand

- asmline can now count the number of instructions that breaks a chunk boundary

- the number of instructions that break a chunk boundary can be counted when 
  assembling a file. 

- adding `cpuid`-instruction

version 1.2.1-release (2022-02-23)

- Fixed bugs regarding `-imm/8`

version 1.2.0-release (2022-02-19)

• binary file can now be generated from libassemblyline with asm_create_bin_file()

• reformatted man page for wide screen

• added support for all operand encodings for and, or, xor, sub, and add instructions

• added support for all setcc instructions - set byte on condition

• added a command-line option in asmline for setting assembly mode to NASM $ asmline --nasm-sib-no-base where:
  in SIB addressing if there is no base register present and scale is equal to 2;
  the base register will be set to the index register and the scale will be reduced to 1.
  That is: "lea r15, [2rax]" -> "lea r15, [rax+1rax]" -> 4c 8d 3c 00

• added a command-line option in asmline for setting assembly mode to STRICT $ asmline --strict-sib-no-base where:
  in SIB addressing when there is no base register present the index and scale would
  not change regardless of scale value.
  That is: "lea r15, [2rax]" -> "lea r15, [2rax]" -> 4c 8d 3c 45 00 00 00 00

version 1.1.0-release (2022-01-21)

• added support for scaled index addressing mode with syntax [base + scaleindex + offset] or [base + indexscale + offset] ex: "add rax, [rcx+4rbp+0x8]" or "add rax, [rcx+rbp4+0x8]"

• added support for MMX, SSE2, AVX, and AVX2 instruction sets

• added support for pointers: byte, word, dword, and qword

• added support for mov [MEM], IMM such as mov [rsi], "0xADE1A1DE"

• added different modes of register size handling for "mov register, immediate" instruction: NASM, STRICT, SMART

• improved 32-bit register supportability: using eax-r15b for memory addressing in vector extension now produces the correct prefix (67H)

• improved intel x86_64 instruction supportability: source code is now more inline with the intel manual, therefore more instructions can be supported in the near future

• added a command-line option in asmline for setting assembly mode to NASM '$ asmline -n' where: if immediate size for mov is less than or equal to max signed 32-bit asmline will emit code to mov to 32-bit register rather than 64-bit. That is: "mov rax, 0x7fffffff" as "mov eax, 0x7fffffff" -> b8 ff ff ff 7f note: rax got optimized to eax for faster immediate to register transfer and produces a shorter instruction.

• added a command-line option in asmline for setting assembly mode to STRICT '$ asmline -t' where: ex: even if immediate size for mov is less than or equal to max signed 32-bit pad the immediate to fit 64bit. That is: "mov rax,0x7fffffff" as "mov rax,0x000000007fffffff" -> 48 b8 ff ff ff 7f 00 00 00 00

• added a command-line option in asmline for setting assembly mode to SMART '$ asmline -s' where: asmline will check the immediate value for leading 0's and thus allows manual optimizations. Immediate must be zero padded to 64-bits exactly to ensure it will not optimize. This is currently set as default. ex: "mov rax, 0x000000007fffffff" -> 48 b8 ff ff ff 7f 00 00 00 00 "mov rax, 0x7fffffff" -> b8 ff ff ff 7f

• assemblyline functions without asm_ prefix are now deprecated

• simplified the process for adding new instructions

• improvements to autotools, including use of pkg-config. That enables other autotools-based projects to include assemblyline as such: add to their configure.ac:

AC_SUBST([LIBASSEMBLYLINE_CFLAGS]) 
AC_SUBST([LIBASSEMBLYLINE_LIBS]) 
PKG_CHECK_MODULES([LIBASSEMBLYLINE], [assemblyline >= 1.1.0]) 

• tools/asmline dynamically links to libassemblyline.so

• tools/asmline's -r[=LEN] option now runs with six arguments, which point to heap-memory. Each argumenty points to LEN (defaults to ten) 64-bit elements. It also features now --rand, which initializes those pointers to random data.

• added asmline 1 and libassemblyline 3 man-page

• added man-pages for all the functions from libassemblyline (same content)
