--- Comment #23 from Iain Sandoe <iains at gcc dot gnu.org> --- Created attachment 33741 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=33741&action=edit asm and .i I built 216304+removing the two sections in i386.md. A stage 1 compiler built with -O0 -g is suffient to show the issue - so it's possible to debug without needing a Darwin box. Attached the .i and .s files for the first file to fail from doing make all-target-libquadmath at stage #1. As you will see there is no picbase being output for the function (there should be a call to a thunk and a label L1$pb0). Will sort out the tree dumps tomorrow ..
