This patch removes real_sqrt. (I rather hope that in general little if any floating-point constant folding is happening on RTL - it doesn't seem like the sort of thing for which RTL expansion should be expected to introduce new folding opportunities, and if it does I'd tend to think that indicates a deficiency in the GIMPLE optimizers.)Bootstrapped with no regressions on x86_64-unknown-linux-gnu. OK to commit? 2013-11-20 Joseph Myers <jos...@codesourcery.com> * real.c (real_sqrt): Remove function. * real.h (real_sqrt): Remove prototype. * simplify-rtx.c (simplify_const_unary_operation): Do not fold SQRT using real_sqrt.
I think you can close PR 55950 with that one. -- Marc Glisse
