annotate gen/optimizer.cpp @ 131:5825d48b27d1 trunk
[svn r135] * Merged DMD 1.025 *
* Fixed a minor linking order mishap *
* Added an command line option -annotate *
* Fixed some problems with running optimizations *
* Added std.stdio and dependencies to lphobos (still not 100% working, but compiles and links) *
* Fixed problems with passing aggregate types to variadic functions *
* Added initial code towards full GC support, currently based on malloc and friends, not all the runtime calls the GC yet for memory *
* Fixed problems with resolving nested function context pointers for some heavily nested cases *
* Redid function argument passing + other minor code cleanups, still lots to do on this end... *
