...n and the pass constructor. Then clang (or whatever is setting up the pass manager) can query the appropriate target info to pass down this flag. Longer term, I'd like to introduce a simple interface (via TargetRegistry) for exposing target libcall info. This would be useful to eliminate the HAVE_FLOORF etc #defines in simplifylibcalls, which break cross compilation. -Chris

The newlib C library provides iprintf(), a restricted version of printf without support for floating-point formatting. I'd like to add an optimization which turns calls to printf() into calls to iprintf() if the format string has no floating point specifiers. At the moment I've got this working locally by adding code to the simplify-libcalls pass. However this will break on targets

This would be useful to eliminate the HAVE_FLOORF etc #defines in simplifylibcalls, which break cross compilation. Hi Richard, Just to close the loop on this, I went ahead and added a new llvm/Target/TargetLibraryInfo.h and added it to simplifylibcalls. TargetLibraryInfo doesn't handle all the libcalls that SimplifyLibCalls handles yet, but...
