--- Comment #8 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-14 branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:326b6bac1f61302daf285e45baf39a6a30511272 commit r14-11149-g326b6bac1f61302daf285e45baf39a6a30511272 Author: Jakub Jelinek <ja...@redhat.com> Date: Sat Nov 30 11:19:12 2024 +0100 openmp: Add crtoffloadtableS.o and use it [PR117851] Unlike crtoffload{begin,end}.o which just define some symbols at the start/end of the various .gnu.offload* sections, crtoffloadtable.o contains const void *const __OFFLOAD_TABLE__[] __attribute__ ((__visibility__ ("hidden"))) = { &__offload_func_table, &__offload_funcs_end, &__offload_var_table, &__offload_vars_end, &__offload_ind_func_table, &__offload_ind_funcs_end, }; The problem is that linking this into PIEs or shared libraries doesn't work when it is compiled without -fpic/-fpie - __OFFLOAD_TABLE__ for non-PIC code is put into .rodata section, but it really needs relocations, so for PIC it should go into .data.rel.ro/.data.rel.ro.local. As I think we don't want .data.rel.ro section in non-PIE binaries, this patch follows the path of e.g. crtbegin.o vs. crtbeginS.o and adds crtoffloadtableS.o next to crtoffloadtable.o, where crtoffloadtableS.o is compiled with -fpic. 2024-11-30 Jakub Jelinek <ja...@redhat.com> PR libgomp/117851 gcc/ * lto-wrapper.cc (find_crtoffloadtable): Add PIE_OR_SHARED argument, search for crtoffloadtableS.o rather than crtoffloadtable.o if true. (run_gcc): Add pie_or_shared variable. If OPT_pie or OPT_shared or OPT_static_pie is seen, set pie_or_shared to true, if OPT_no_pie is seen, set pie_or_shared to false. Pass it to find_crtoffloadtable. libgcc/ * configure.ac (extra_parts): Add crtoffloadtableS.o. * Makefile.in (crtoffloadtableS$(objext)): New goal. * configure: Regenerated.
