<div>
<pre>Trying to compile:
"""
#include <cmath>
int Foo(float a) {
if (a / nan("")) return 0;
return 1;
}
"""
never terminates, with the given flags:
-mbig-endian
-mcpu=cortex-r4
-mthumb
-mfpu=vfpv3-d16
-mfloat-abi=hard
--target=armeb-none-eabihf
-ffp-model=strict
Changing the fp-model to precise or float-abi to soft allows compilation to
terminate. The issue appears to related to exceptions with hard-float.</pre>
