[PATCH] D134859: [clang][Interp] Implement basic support for floating point values

[Timm Bäder via Phabricator via cfe-commits]

tbaeder updated this revision to Diff 469166.
tbaeder added a comment.

Another (and even longer) version.

Introduce special opcodes for floating point operations and pass the rounding mode to them. Also create special int->float and float->int casts so we can handle that properly.

This makes `clang/tests/SemaCXX/rouding-math.cpp` work. I've only enabled one of the two RUN lines though. The other one fails because we don't handle `CXXNewExpr`s yet.
