WebMay 20, 2012 · 2 Answers Sorted by: 16 To (greatly) simplify, LLVM is a C++ library for writing compilers. Its C++ API is the external interface users of the library employ to implement their compiler. There's a degree of symmetry between LLVM IR and part of the LLVM C++ API - the part used to build IR. WebFor gcc, the manual explains what -O3, -Os, etc. translate to in terms of specific optimisation arguments (-funswitch-loops, -fcompare-elim, etc.) I'm looking for the same info for clang.. I've looked online and in man clang which only gives general information (-O2 optimises more aggressively than -O1, -Os optimises for size, ...) and also looked here on Stack …

However, the former loop is in LCSSA (loop closed SSA) form. This form provides some very useful guarantees which simplify many loop optimisations. This isn't specific to LLVM, GCC does this as well.
