Jan, This patch is causing a bootstrap failure on AIX. It generates linker errors that TOC symbols are not emitted:
ld: 0711-317 ERROR: Undefined symbol: LC..0 ld: 0711-317 ERROR: Undefined symbol: LC..1 ld: 0711-317 ERROR: Undefined symbol: LC..2 ld: 0711-317 ERROR: Undefined symbol: LC..3 ld: 0711-317 ERROR: Undefined symbol: LC..4 Although pLinux uses the same code, GCC is able to bootstrap on Linux. The function in question is gcc/config/rs6000/rs6000.c:output_toc() Do you have any suggestions on what is missing in the label allocation that causes your cgraph change to believe the symbols are unreferenced? I have opened PR bootstrap/53300. Thanks, David
