disassemble ( obj -- )
Factor handbook » Developer tools » Disassembling words

Vocabulary
tools.disassembler

Inputs

obj	a word or a pair of addresses

Outputs
None

Word description
Disassembles either a compiled word definition or an arbitrary memory range (in the case obj is a pair of integers).

Notes
In some cases the Factor compiler emits data inline with code, which can confuse the disassembler. This occurs in words which call dispatch, where the jump table addresses are compiled inline.
