Just Testing

Ok, I've got the stage3 build with RTS and Libs working with -fasm -O2. Did a full testsuite run last night, and it looks promising. However, a stack of the driver tests failed because the compiler or build system spews something about "/bin/sh: cygpath: not found". This line isn't in the file its testing against, which results in a failure.

.. the cygpath thing was easy enough to hack around. A full stage3 test run gives the following. I've sorted the failing tests by ways failed.

A good percentage of these are seg faulting, so there is still a bug or two lurking around.

Continued to split the native code generator into arch specific modules while waiting for test runs. I'm splitting into Alpha, X86, PPC, and SPARC subdirs. The Alpha code is long dead, but it seems a shame to just delete it, so I've made modules for it but commented it out in those modules.

Due to time constraints I'll have to leave some of the #ifdefs in, expecially for the difference between i386 and x86_64. There are also some #ifdefs to choose between Darwin and other OSs.

The way it setup now is that (almost) all code from all arches gets compiled, no matter what the host platform is. This means that potential validate problems are always exposed. It should also help reduce the rot-factor for seldom used platforms.

The top level modules like MachCodeGen still have an #ifdef to choose which one to import for the specific platform. However, it should be straight forward to go from this setup to having a data type representing the target platform, and being able to specify it on the command line.

On the SPARC front, I've just finished cleaning up the horror show that was nativeGen/MachRegs.hs. I'll spare you the details, but this source comment (not mine) sums it up nicely: "Gag me with a spoon, eh?"

It feels a lot simpler when all the SPARC code is isolated, and you don't have to expend mental effort to reject code for architectures you're not working on. It's also reassuring to know that if you change something you're not going to break something for another architecture that is in an #ifdef block that isn't being compiled on the current platform.

Also went through and fixed all the warnings in code from MachRegs, MachInstrs, RegsAllocInfo and PprMach. The world seems shiny and new.
