No, it doesn't have any effect on the results, but it produces slightly less optimized code. The main problem there is that it fails to build when enforcing type checking, though less and less targets are compiling when it is enabled. > Can we have the usual "ok under softfloat 2a or 2b license" > confirmation, please? Yes, I am fine to license this patch under softfloat 2a or 2b license. Aurelien

The roundAndPackFloat16 function should return a float16 value, not a float32 one. Fix that. Cc: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> --- fpu/softfloat.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
