Currently, clang and +GCC's MinGW targets both only support DW2 (DWARF) or SJLJ (Set Jump Long +Jump) unwinding on 32-bit Windows. + +The default for GCC (and the way it is shipped on every major distro) is +to use SJLJ on Windows, as DWARF cannot traverse non-DWARF frames. This +would work fine, except for the fact that libgcc (our C runtime on the +MinGW platform) exports symbols under a different name when configured +to use SJLJ-style unwinding, and uses a preprocessor macro internally to +alias them. + +Because of this, we have to detect this scenario and link to the correct +symbols ourselves. Linking has been tested with a full bootstrap on both +x86_64-unknown-linux-gnu and i686-pc-windows-gnu, as well as +cross-compilation of some of my own projects. + +Obviously, the detection is a bit unrefined. Right now we +unconditionally use SJLJ when compiling Linux -> MinGW. I'd like to add +feature detection using compiler build flags or autotools-style +compilation and object analysis. Input on the best way to proceed here +is welcome. + +Also, currently there is copy-pasted/duplicated code in libunwind. +Ideally, this could be reduced, but this would likely require a +rethinking of how iOS is special-cased above, to avoid further +duplication.
