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)
