            Bug ID: 80199
           Summary: Wlogical-op inconsistent from int to float ?
           Product: gcc
           Version: 7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dcb314 at hotmail dot com
  Target Milestone: ---

For the following C++ code:

void g1( float );
void g2( int );

void
f1( float a)
{
        if (a < 0.0 && a > 1.0)
                g1( a);
}

void
f2( int a)
{
        if (a < 0 && a > 1)
                g2( a);
}

I get only one warning, not the expected two:

$ ~/gcc/results/bin/g++ -g -O2 -Wall -Wlogical-op -Wextra -c mar26e.cc
mar26e.cc: In function ‘void f2(int)’:
mar26e.cc:15:12: warning: logical ‘and’ of mutually exclusive tests is always
false [-Wlogical-op]
  if (a < 0 && a > 1)
      ~~~~~~^~~~~~~~
$ ~/gcc/results/bin/g++ -v
