From: "cvs-commit at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug target/99783] relocation truncated to fit: R_OR1K_GOT16 on OpenRISC, building libgeos Date: Sat, 14 Aug 2021 22:23:23 +0000 [thread overview] Message-ID: <bug-99783-4-GRP0pChpw5@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-99783-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99783 --- Comment #3 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Stafford Horne <shorne@gcc.gnu.org>: https://gcc.gnu.org/g:eff8110674ef193481d3657456a262beeb9951ff commit r12-2909-geff8110674ef193481d3657456a262beeb9951ff Author: Stafford Horne <shorne@gmail.com> Date: Tue Apr 6 05:47:17 2021 +0900 or1k: Add mcmodel option to handle large GOTs When building libgeos we get an error with: linux-uclibc/9.3.0/crtbeginS.o: in function `__do_global_dtors_aux': crtstuff.c:(.text+0x118): relocation truncated to fit: R_OR1K_GOT16 against symbol `__cxa_finalize' defined in .text section in /home/shorne/work/openrisc/3eb9f9d0f6d8274b2d19753c006bd83f7d536e3c/output/host/or1k-buildroot-linux-uclibc/sysroot/lib/libc.so. This is caused by GOT code having a limit of 64k. In OpenRISC this looks to be the only relocation code pattern to be limited to 64k. This patch allows specifying a new option -mcmodel=large which can be used to generate 2 more instructions to construct 32-bit addresses for up to 4G GOTs. gcc/ChangeLog: PR target/99783 * config/or1k/or1k-opts.h: New file. * config/or1k/or1k.c (or1k_legitimize_address_1, print_reloc): Support generating gotha relocations if -mcmodel=large is specified. * config/or1k/or1k.h (TARGET_CMODEL_SMALL, TARGET_CMODEL_LARGE): New macros. * config/or1k/or1k.opt (mcmodel=): New option. * doc/invoke.texi (OpenRISC Options): Document mcmodel.
