IDA Pro as a disassembler is capable of creating maps of their execution to show the binary instructions that are actually executed by the processor in a symbolic representation (assembly language). Advanced techniques have been implemented into IDA Pro so that it can generate assembly language source code from machine-executable code and make this complex code more human-readable.
If you're just looking to use a disassembler, then objdump is one choice. The disassembler that comes with the nasm assembler is ndisasm. You can also run "debug.exe" in DOS Box on Linux, provided you get a hold of a copy of the program. It also does disassembly, as well as controlled execution; i.e. simulation of the CPU, itself - which is also important, even when doing disassembly, for reasons I'm about to describe.
This gets to the other sense of your query: "I want to make a disassembler". The source for ndisasm is available, and it handles many of the descendants of 8086, not just 8086, itself (which seriously clutters it, if all you want is an 8086 or even 80386 disassembler), but it is not self-contained and has a heavy dependency on the rest of the distribution.
Its main talking point is that it uses octal digits for the opcodes - which better fits the 80x86 - as I pointed out on the USENET in 1995 in comp.lang.asm ... and (in fact) nasm's creation was a direct response to that. So, it's potentially more transparent and you may want to keep the source handy as a check and comparison, if you're making your own disassembler.
And then you've just disassembled a disassembler that also happens to do CPU emulation, like Fake86 does - but only for the 8086. You'll have to make the absolute addresses relative (using the original relocation table as a guide), to make is re-assemblable. Once you do that, you can work on the source. The opcode table is in clear view (if you display it as text) - both when seen in the packed and unpacked versions of debug.exe.
There's also DosDebug up on GitHub. It handles everything up to "80586" (or Pentium") and "80686": it flags a generation "6" for some instructions.; e.g. the conditional "cmov" operations are handled by it, as well as their "fcmov" floating point versions. DosDebug is in 8086 assembly and is best-suited to compile with jwasm. You might be able to run nasm on it, I don't know. I never tried.
I might port the DAS disassembler to the x86, since items (a)-(f) are already incorporated into DAS's design. I've only ever ported it to the 8051, 6800, 6809 and 8080/8085 (and Z80) up to now; but the transition from 8085 to 8086 is relatively small. To that end, I might hack something out of Fake86. That's mostly abandonware, now, since the author replaced it by XTulator, as Fake86 was written when the programmer was relatively new to C. You might also be able to hack something directly out of DosDebug's opcode tables (their "instr.*" files).
The rows in the mix output histograms come in two flavors. The rows that begin with "*" are meta-categories which sum up the data in different ways. Here are descriptions of some of the meta categories:*scalar-simd anything with the XED_ATTRIBUTE_SIMD_SCALAR including AVX and SSE operations. The instructions that operate on one vector element and whose iclass name ends with "SS" or "SD" have this attribute.*sse-scalar any SSE instruction with the XED_ATTRIBUTE_SIMD_SCALAR*sse-packed any SSE instruction without the XED_ATTRIBUTE_SIMD_SCALAR*avx-scalar Any AVX instruction with the attribute XED_ATTRIBUTE_SIMD_SCALAR*avx128 Any AVX instruction with a 128b vector length but without the XED_ATTRIBUTE_SIMD_SCALAR*avx256 Any AVX instruction with a 256b vector length*avx512 Any AVX instruction with a 512b vector length.*mem-atomic Atomic memory operations*stack-read Stack reads*stack-write Stack writes*iprel-read IP-relative memory reads*iprel-write IP-relative memory writes*mem-read-1 Memory read, 1 byte*mem-read-2 Memory read, 2 bytes*mem-read-4 Memory read, 4 bytes*mem-read-8 Memory read, 8 bytes*mem-write-1 Memory write, 1 byte*mem-write-2 Memory write, 2 bytes*mem-write-4 Memory write, 4 bytes*mem-write-8 Memory write, 8 bytes*isa-ext-BASE The "BASE" ISA-extension (generic group of instructions.

It's operationis controlled by a command file, which tells it what binary code imagefile(s) to load, the addresses for code entry points such as RST, NMI,etc. (optional), and the addresses for any code or subroutines whichmay not be explicitly called within the MC6800/6802 code. The programthen processes the code, tracing execution paths and identifying jumplocations, subroutines and data tables. The program output is normallyin "list" format, with an address column at the start of each line,however, this address column is omitted if the specified output filename ends in ".ASM".

Based on Intel's iammx.inc file, I managed to create a new set of macros using Ideal programming mode. I have also included an example on how to use them and how they are transparent. The example is MSDOS based and I did not include a pre-compiled version, instead, I included a makefile for easy creation. The example uses case-sensitivity compilation but the macros will work well without it. This is still a beta release. I expect to have some bugs even if I tested every instructions.
