2011-01-02softfloat: Rename float*_is_nan() functions to float*_is_quiet_nan()Peter Maydell
The softfloat functions float*_is_nan() were badly misnamed, because they return true only for quiet NaNs, not for all NaNs. Rename them to float*_is_quiet_nan() to more accurately reflect what they do. This change was produced by: perl -p -i -e 's/_is_nan/_is_quiet_nan/g' $(git grep -l is_nan) (with the results manually checked.)

2009-10-01Revert "Get rid of _t suffix"Anthony Liguori
In the very least, a change like this requires discussion on the list. The naming convention is goofy and it causes a massive merge problem. Something like this _must_ be presented on the list first so people can provide input and cope with it. This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.
