- Compiler no longer works on its own, it requires Assembler. - Labels created by Assembler and Compiler now share their IDs, so they can be used nearly interchangeably without weird side-effects and hacks. - Renamed getError() and setError() to getLastError() and setLastError(). - Renamed compiler nodes to "HL" nodes (preparation for HLStream). - Renamed FuncConv to CallConv. - Function calling convention is now part of FuncPrototype. - Added a possibility to align by inserting zeros (kAlignZero) - Fixed assertion in X86Compiler that didn't like unhandled function argument(s). - Added Compiler::embedConstPool() helper, which can be handy if you use your own ConstPool. - Code refactorization and other minor changes. - CpuTicks::now() renamed to Utils::getTickCount(). - error.h merged with globals.h - Documentation updates related to recent API changes.

Compiler now attaches to Assembler. This change was required to create resource sharing where Assembler is the central part and Compiler is a "high-level" part that serializes to it. It's an incremental work to implement sections and to allow code generators to create executables and libraries.
Also, Compiler has no longer Logger interface, it uses Assembler's one after it's attached to it.
JitRuntime runtime;
X86Compiler c(&runtime);
// ... code generation ...
void* p = c.make();
to
JitRuntime runtime;
X86Assembler a(&runtime);
X86Compiler c(&a);
// ... code generation ...
c.finalize();
void* p = a.make();
All nodes were prefixed with HL, except for platform-specific nodes, change:
Node -> HLNode
FuncNode -> HLFunc
X86FuncNode -> X86Func
X86CallNode -> X86Call
FuncConv renamed to CallConv and is now part of a function prototype, change:
compiler.addFunc(kFuncConvHost, FuncBuilder0<Void>());
to
compiler.addFunc(FuncBuilder0<Void>(kCallConvHost));
Operand constructors that accept Assembler or Compiler are deprecated. Variables can now be created by using handy shortcuts like newInt32(), newIntPtr(), newXmmPd(), etc... Change:
X86Compiler c(...);
Label L(c);
X86GpVar x(c, kVarTypeIntPtr, "x");
to
X86Compiler c(...);
Label L = c.newLabel();
X86GpVar x = c.newIntPtr("x");
