Bug ID: 88078
Summary: error: '__float128' was not declared in this scope on
PowerPC
Product: gcc
Version: 8.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: noloader at gmail dot com
Target Milestone: ---
I'm working on GCC112 from the compile farm. I'm having trouble compiling a
program with the C++ compiler.
$ cat test.cxx
#include <altivec.h>
#undef vector
#undef pixel
#undef bool
#include <string>
#include <vector>
typedef __vector unsigned char uint8x16_p;
uint8x16_p Foo(const unsigned char* ptr)
{
return vec_ld(0, ptr);
}
=========================
Compiling results in:
$ /opt/cfarm/gcc-latest/bin/g++ -mcpu=power4 -maltivec -c test.cxx
