Bug ID: 104253 Summary: libgcc missing __floatdiif Product: gcc Version: 11.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: murphyp at linux dot vnet.ibm.com CC: bergner at gcc dot gnu.org, meissner at gcc dot gnu.org Target Milestone: --- When compiling something which uses the __ibm128 type, an instrinsic function call is generated which is not satisfied at link time. E.g foo.c: #include <stdio.h> #include <stdlib.h> int main(int a, char **v) { long d = strtol(v[1],0,0); __ibm128 i = d; printf("%a %a\n",__builtin_unpack_ibm128(i,0),__builtin_unpack_ibm128(i,1)); return 0; } gcc -O2 foo.c -o foo: /usr/bin/ld: /tmp/ccuWW1m0.o: in function `main': foo.c:(.text.startup+0x2c): undefined reference to `__floatdiif' collect2: error: ld returned 1 exit status This happens on a ppc64le machine running fedora rawhide, gcc -v: Using built-in specs.
