--- Comment #1 from David Binderman <dcb314 at hotmail dot com> ---
Same thing a few lines further down in the same file:
trunk/libgcc/soft-fp/op-common.h:913:10: warning: this statement may fall
through [-Wimplicit-fallthrough=]
Source code is
case _FP_CLS_COMBINE (FP_CLS_INF, FP_CLS_NAN): \
case _FP_CLS_COMBINE (FP_CLS_ZERO, FP_CLS_NAN): \
R##_s = Y##_s; \
\
case _FP_CLS_COMBINE (FP_CLS_NORMAL, FP_CLS_INF): \
case _FP_CLS_COMBINE (FP_CLS_NORMAL, FP_CLS_ZERO): \
And a third case in the same file, line 1200:
case _FP_CLS_COMBINE (FP_CLS_NORMAL, FP_CLS_ZERO): \
FP_SET_EXCEPTION (FP_EX_DIVZERO); \
case _FP_CLS_COMBINE (FP_CLS_INF, FP_CLS_ZERO): \
