Consider mode of target type in determining decimal type for arithmetic. Unless flag_unsafe_math_optimizations, do not optimize binary conversions where this may change rounding behavior. * real.c (real_can_shorten_arithmetic): New. * real.h (real_can_shorten_arithmetic): Declare. gcc/testsuite/ Backport from mainline: 2008-10-29 Joseph Myers <jos...@codesourcery.com> PR middle-end/36578 * gcc.dg/dfp/convert-bfp-13.c, gcc.dg/dfp/convert-bfp-14.c, gcc.dg/dfp/convert-dfp-fold-2.c, gcc.target/i386/pr36578-1.c, gcc.target/i386/pr36578-2.c: New tests.
