Does it mean we need to make sure GCC 13 released after binutils-2.40? binutils-2.39 release branch is already created and it's now explicitly "no new feature" so a backport seems impossible... > + </li> > + <li>The method for calling global functions changed from > + <code>la.global + jirl</code> to <code>bl</code> when complied add > + <code>-fplt</code>. "from la.global + jirl to bl with -fno-plt and -mexplicit-relocs"? With "-fplt" GCC 12 is already using bl, and with -mno-explicit-relocs la.global is still used (if I read func-call-3.c correctly). > + <li>Enable option <code>-fsection-anchors</code> when <code>-O1</code> and > + more advanced optimization.
