* Harpy NEWS
** New in version 0.4
- New convenience top-level module "Harpy", which re-exports
Harpy.CodeGenMonad, Harpy.Call and Harpy.X86Assembler
- It is now possible to override Harpy's automatic code buffer
management. The new field 'customCodeBuffer' in the type
'CodeGenConfig' can be set to 'Just (buf, size)', where 'buf' is a
pointer to a memory region of 'size' bytes. Harpy will then use the
supplied code buffer and will not perform any automatic code buffer
allocation on overflow. Overflow checking is still performed and
will result in an exception in the CodeGen monad.
- When using the high-level assembler in X86Assembler, the code buffer
is automatically protected from overflow.
- Floating point operations added to X86Assembler (only for double
operands yet).
- Preliminary support for SSE instructions. Currently, only the
packed and scalar floating-point arithmetic operations are supported
(both in the low-level module Harpy.X86CodeGen and as methods in
Harpy.X86Assembler)
- Code buffer default size has been increased from 128 to 4096 bytes.
- The CodeGenMonad fails when a label is defined twice.
- It is now possible to associate names with labels, using the new
operation newNamedLabel. The given names will show up in the
disassembly, which makes debugging of generated code much easier.
- The doc directory contains a second, slightly larger tutorial now.
- The examples/evaluator directory contains a small example
interpreter for arithmetic expressions, which translates expressions
entered at the keayboard to machine code on the fly. This is the
demo program we presented at the Haskell Workshop 2007.
** New in version 0.2
- Everything is new! This is the first released version.
