re PR middle-end/36578 (cast to long double not taken into account when result stored to a double)
PR middle-end/36578
* convert.c (convert_to_real): Do not optimize conversions of
binary arithmetic operations between binary and decimal
floating-point types. 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.
testsuite:
* 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.
