Add Disassembly Source Code Highlighting for ARM Assembler Output

[PrzemekWirkus]

Introduction

We propose adding a new feature to the WindowsPerf VS-extension that provides syntax highlighting for ARM assembler output in the disassembly view.

DOD:

• Improve general assembly formatting e.g. make sure all mnemonics and instruction arguments are evenly spread.

OK:

AND    r0, r1, r2 ; r0 := r1 and r2
ORR    r0, r1, r2 ; r0 := r1 or r2
EOR    r0, r1, r2 ; r0 := r1 xor r2
BIC    r0, r1, r2 ; r0 := r1 and not r2

NOK:

AND   r0,   r1, r2 ; r0 := r1 and r2
ORR  r0, r1, r2 ; r0 := r1 or r2
EOR   r0, r1, r2    ; r0 := r1 xor r2
BIC r0, r1, r2    ; r0 := r1 and not r2

• Implement syntax highlighting rules specific to Arm assembler syntax provided with WindowsPerf JSON output (LLVM objdump based output).
• Provide customization options for users to adjust the highlighting colors and styles according to their preferences.
  • in Extension options users should be able to turn on/off syntax highlighting.
• No performance degradation in the disassembly view with the new highlighting feature enabled.
  • We should make sure syntax highlighting is "instant" and do not influence extension performance.
• Highlighting rules correctly identify and color-code ARM instructions, registers (, and comments).

@Alaaeddine-chakroun Here's a example output from llvm-objdump for few ARM64 executables:

• branch_direct_workload.txt
• fpsqrt_workload.txt
• int2double_workload.txt
• wperf.txt.zip

@Alaaeddine-chakroun Also added you Python3.dll, one we use in examples :)

• python312_d.dll.txt.zip
