bddisasm is a fast, lightweight, x86/x64 instruction decoder. The project also features a fast, basic, x86/x64 instruction emulator, designed specifically to detect shellcode-like behavior.
Similar to #22 et al.: PCOMMIT was never introduced in any real x86 hardware. Intel specified it and made compiler changes, but every real x86 CPU will emit an #UD when given a PCOMMIT instruction sequence.
This should probably be either removed or feature-gated behind a flag.
