math-emu: Fix thinko in _FP_DIV

60b82673 · David S. Miller <[email protected]> · 2008-10-22 22:09:59 -07:00

In commit 48d6c64311ddb6417b901639530ccbc47bdc7635 ("math-emu: Add
support for reporting exact invalid exception") code was added to
set the new FP_EX_INVALID_{IDI,ZDZ} exception flag bits.

However there is a missing break statement for the
_FP_CLS_COMBINE(FP_CLS_INF,FP_CLS_INF) switch case, the
code just falls into _FP_CLS_COMBINE(FP_CLS_ZERO,FP_CLS_ZERO)
which then proceeds to overwrite all of the settings.

Fix by adding the missing break.
