It is now (optionally) pure via the MonadThrow class. It also exposes a new
binary format repr, which currently only has constructors for ELF containers.
The generic binary loading interface is instantiated once for each
architecture/binary container pair. This isn't great, but there is enough
custom work in each setting to justify it.
The binary loading interface isn't finished yet, and needs to learn some
additional operations to support relocation. It already supports additional
information that is architecture specific and binary container format
specific (that operations will have to use on a per-format basis).
On the PowerPC side, the Table of Contents (TOC) is now architecture-specific
information constructed by the loader (currently from ELF binaries). The new
TOC data type is in place to support this more easily (the old format was just a
function).
This code was mostly architecture independent already, so this commit moves it
to the macaw-semmc module so that it can be shared with the ARM backend. I
still plan to move the main TH module with the SimpleBuilder to macaw
translation, but that requires a few other changes first.
