Bug ID: 82626
Summary: -msse and -mfpmath=sse Causes __FLT_EVAL_METHOD__ to
be -1
Product: gcc
Version: 6.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: regression
Assignee: unassigned at gcc dot gnu.org
Reporter: gcc at grundis dot de
Target Milestone: ---
This was detected when compiling this:
echo "#include <cmath>" | g++ -x c++ - -msse -mfpmath=sse -o /dev/null
This combination of flags seems to cause a definition of __FLT_EVAL_METHOD__=-1
while it should be 2(?). This causes more issues later on code that relies on
that define. See https://sourceforge.net/p/mingw/bugs/2352/
