Summary:

0000176: Undefined reference to '__builtin_*' functions with new gcc versions. |
|
Description:
|
Using 'isnan' from math.h results into a call to __builtin_isnan (isnan is a makro).
In new gcc versions (gcc 6.1.1 20160501) some __builtin_* functions are not available for linking any more, since gcc translates them directly into opcodes.
At least the following functions are affected:
__builtin_isnan
__builtin_isinf_sign
__builtin_isnormal
__builtin_signbit
...
Reproduce:
1. Create a file (test.c) containing
#include <math.h>
double g = 0;
int main() {
return isnan(g);
}
2. 'gcc test.c' works fine
3. 'cparser test.c' outputs a linker error:
/tmp/05a1m7/a-0-1.o: In function `main':
(.text+0x13): undefined reference to `__builtin_isnan'
collect2: error: ld returned 1 exit status
a.out: error: linker reported an error
