-*-outline-*- * Harpy NEWS ** New in version 0.6.0.0 *** Re-licensed under BSD3 *** Updated to work with GHC 7.8.3 ** New in version 0.4.2 *** package structure - The disassembler is now in a separate package, and is re-exported for compatibility by Harpy. This allows us to give the more liberal BSD licence to the disassembler. *** New instructions - The "mov", "jcc" (jump on condition code), and "cmp" instructions support "Ptr a" as operand - Henning Thielemann provided some further floating point and SSE instructions. - The loop instruction supports labels now. *** Enhancements - The disassembly of Harpy's internal code buffers includes all labels now, even when multiple labels are defined for the same location. ** New in version 0.4.1 *** New Instances - Many of Harpy's types are now instances of Eq. *** New instructions - Added support for the prefetching instructions PREFETCH0, PREFETCH1, PREFETCH2 and PREFETCHNTA. *** Bug fixes - Harpy.X86Disassembler.disassembleBloc was too strict and caused stack overflows for large inputs. This was fixed. - Disassembler: The instruction prefix list was not cleared when beginning to parse a new instruction. This caused incorrect disassembly of SSE instructions. - Disassembler: A bug has been fixed in the parsing routine for the addressing mode "scaled index + 32 bit offset" without base register. ** 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.
