Description
Harpy is a library for run-time x86 code generation in Haskell programs. Harpy requires several Haskell extensions and GHC-specific features (the Haskell FFI, Template Haskell, multi-parameter type classes and monad transformers).
Limitations
- 64-bit mode is not supported
- MMX, SSE, SSE2 and SSE3 instructions and registers are not supported.
- The disassembler supports (in principle) 64-bit mode and SSE instructions, but this has not been tested.
- Buffer overflow checks have to be done manually with checkBufferSize or ensureBufferSize
Tutorials
