6598 which relies on rounding behavior like `(x + 2**52) - 2**52)'.
6655 floating point rounding behavior. This is round-to-zero for all
6658 for programs that change the FP rounding mode dynamically, or that
6659 may be executed with a non-default rounding mode. This option
6661 compile-time (which may be affected by rounding mode) and
6663 sign-dependent rounding modes.
6665 The default is `-fno-rounding-math'.
6668 disable all GCC optimizations that are affected by rounding mode.
10227 `-mfp-rounding-mode=ROUNDING-MODE'
10228 Selects the IEEE rounding mode. Other Alpha compilers call this
10229 option `-fprm ROUNDING-MODE'. The ROUNDING-MODE can be one of:
10232 Normal IEEE rounding mode. Floating point numbers are
10240 Chopped rounding mode. Floating point numbers are rounded
10244 Dynamic rounding mode. A field in the floating point control
10246 controls the rounding mode in effect. The C library
10247 initializes this register for rounding towards plus infinity.
