Bug ID: 84654
Summary: libstdc++ tries to use __float128 when compiling with
-mno-float128
Product: gcc
Version: 8.0.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: tuliom at linux dot vnet.ibm.com
Target Milestone: ---
Using the following test program:
$ cat test1.cpp
#include <math.h>
int main() {
return 0;
}
$ g++-8 -mno-float128 test.cpp
In file included from /usr/include/c++/8/cmath:47,
from /usr/include/c++/8/math.h:36,
from test.cpp:1:
/usr/include/c++/8/bits/std_abs.h:101:3: error: ‘__float128’ does not name a
type; did you mean ‘__floorl’?
__float128
^~~~~~~~~~
__floorl
I reproduced this problem on powerpc64le.
I have a patch to fix this.
