Summary: warning: assuming signed overflow does not occur
when simplifying conditional to constant
Description:
Cmake generates code which confuses gcc optimizer:
/home/mathieu/Perso/gdcm-gcc/Testing/Source/Common/Cxx/gdcmCommonTests.cxx: In
function ‘int main(int, char**)’:
/home/mathieu/Perso/gdcm-gcc/Testing/Source/Common/Cxx/gdcmCommonTests.cxx:218:
warning: assuming signed overflow does not occur when simplifying conditional to
constant [-Wstrict-overflow]
Code generated by cmake is:
...
/* If partial match is requested. */
if(testToRun == -1 && ac > 1)
{
partial_match = (strcmp(av[1], "-R") == 0) ? 1 : 0;
}
...
Looks like gcc thinks ac can be negative...
