Clang -O3 compile+run core kernel, Clang functional for almost all features, assorted bug fixes #15

Closed PeterDinda closed 5 years ago

PeterDinda commented 5 years ago

This sequence of commits do the following

  1. They make the core kernel compile and run successfully with Clang 3.7/8 and Clang 6.0, as we well as GCC (5.4). Basically, on all the default ("apt get") environments in Ubuntu 16. On Clang, -O2 now works, as does -O3. The biggest fixes are more boot code to avoid using SSE until the FPU is initialized.

  2. They make almost everything successfully build on Clang 6.0 and GCC 5.4. The exceptions are Legion (not tried), OpenMP tests (work in progress), and LUA tests (I think).

  3. They make the build environment configurable without tweaking the Makefile.

Nice. I was using clang 7 when doing the initial port. I'll have to give this a try on my version.

@PeterDinda it looks like 664c78d is a duplicate of 61b1dcf

Updated the debug test config to include the compiler stuff (gcc). Plus some wonky Makefile crud to get the config targets to work correctly if .config doesn't exist.
