I think there's an alternative to this fix: /* The HP-UX linker has a bug that causes calls from functions in .text.unlikely to functions in .text to cause a segfault. Until it is fixed, prevent code from being put into .text.unlikely or .text.hot. */ #define TARGET_ASM_FUNCTION_SECTION ia64_hpux_function_section In pa.c, we have the following to suppress hot and cold partitioning: /* Disable -freorder-blocks-and-partition as we don't support hot and cold partitioning. */ if (flag_reorder_blocks_and_partition) { inform (input_location, "%<-freorder-blocks-and-partition%> does not work " "on this architecture"); flag_reorder_blocks_and_partition = 0; flag_reorder_blocks = 1; }
