re PR c/53001 (-Wfloat-conversion should be available to warn about floating point errors)
2013-11-19 Joshua J Cogliati <jrincayc@yahoo.com>
PR c/53001
Splitting out a -Wfloat-conversion from -Wconversion for
conversions that lower floating point number precision
or conversion from floating point numbers to integers.
gcc/c-family/
* c-common.c (unsafe_conversion_p): Make this function
return an enumeration with more detail.
(conversion_warning): Use the new return type of
unsafe_conversion_p to separately warn either about conversions
that lower floating point number precision or about the other
kinds of conversions.
* c-common.h (enum conversion_safety): New enumeration.
(unsafe_conversion_p): switching return type to
conversion_safety enumeration.
* c.opt: Adding new warning -Wfloat-conversion and
enabling it with -Wconversion.
gcc/
* doc/invoke.texi: Adding documentation about
-Wfloat-conversion.
gcc/testsuite/
* c-c++-common/Wfloat-conversion.c: Copies relevant
tests from c-c++-common/Wconversion-real.c,
gcc.dg/Wconversion-real-integer.c and gcc.dg/pr35635.c into
new testcase for conversions that are warned about by
-Wfloat-conversion.
