LLVMDisassembler

Pharo bindings to the LLVM disassembler.

Installation

EpMonitor disableDuring: [ 
        Metacello new
                baseline: 'LLVMDisassembler';
                repository: 'github://pharo-project/pharo-llvmDisassembler';
                load ].

To install including the Tests group:

EpMonitor disableDuring: [ 
	Metacello new
		baseline: 'LLVMDisassembler';
		repository: 'github://pharo-project/pharo-llvmDisassembler';
		load: #('Tests') ].

How to depend on it

If you want to add a dependency on LLVMDisassembler to your project, include the following lines into your baseline method:

spec
  baseline: 'LLVMDisassembler'
  with: [ spec repository: 'github://pharo-project/LLVMDisassembler/src' ].

Usage

To create a disassembler, you can use the #createDisassembler: method using a triple name as argument.

LLVMDisassembler createDisassembler: 'x86_64'.

Or use one of the predefined factory methods in the class side such as:

LLVMDisassembler i386.
LLVMDisassembler arm.

The main method of the disassembler is #disassembleInstructionIn:pc: which receives the bytes to disassemble and the current program counter. This method disassembles a single instructions and returns the disassembled text and the number of bytes of the instruction

x86_CODE32 := #[ 16r41 ]. "INC ecx"
llvmDisassembler disassembleInstructionIn: x86_CODE32 pc: 0.
   => #('incl	%ecx' 1)

Alternatively, the convenience method #disassembleNext:instructionsIn:pc: disassembles the next N instructions in the byte array.
