+0.0.4 (8 August 2004)
+
+ * Pluggable object models.
+ * Problems with "gen-apply" on Win32 systems.
+ * Optimize "if true goto" into "goto".
+ * Peephole optimization on branches.
+ * Adjust ARM codegen macros to support branch elimination instructions.
+ * Redesign exception handling to use "setjmp" everywhere.
+ * Remove C++ code from "libjit.so" so that it is a pure C library.
+ * Use computed goto's in the interpreter if the compiler supports them.
+ * Don't allow conditional branches to jump out of exception contexts.
+ * Block movement to allow initialization code to be moved to the start
+ of a function, or loop condition code to be moved to the end.
+ * Rewrite the exception region routines to make them easier to use.
+ * Add the "gen-sel" program, for creating instruction selectors.
+ * Write instruction selectors for x86 and ARM (only x86 is enabled).
+ * Portability fixes for ARM, PPC, Alpha, IA64, and amd64.
+ * Clarify the description of LLVM, at the request of LLVM's author.
+ * Deferred argument popping after function calls.
+ * Add "--enable-interpreter" to force the interpreter to be used.
+ * Implement a simple global register allocator based on usage counts.
+ * Recognise increment and decrement idioms.
+ * Align cache flushes properly (Miroslaw Dobrzanski-Neumann).
+ * Querying of x86 cpuid where necessary.
+ * Add a constant pool for ARM, to make constant loads more efficient.
+ * Handle register pairs for 64-bit values properly.
+ * Support for parameter areas on the stack, to reduce push/pop overhead.
+ * Avoid unnecessary register spills if a value won't be used again.
+ * Implement tail calls from a function to itself.
+ * Optimize x86 prologs and epilogs to avoid doing unnecessry work.
+ * Centralise the code that handles parameter passing.
+ * Support for parallel builds.
+
0.0.2 (13 May 2004)
* Function and instruction building API basics in place, in C and C++.
