#ifdef CRT_GET_RFIB_DATA
nios2: Support for GOT-relative DW_EH_PE_datarel encoding. On nios2-linux-gnu, there has been a long-standing bug in C++ exception handling that sometimes resulted in link errors like ../nios2-linux-gnu/bin/ld: FDE encoding in /tmp/cccfpQ2l.o(.eh_frame) prevents .eh_frame_hdr table being created when building some shared libraries or PIE executables. The root of the problem is that GCC was incorrectly emitting an absolute encoding in EH tables for PIC. This patch changes it to use either DW_EH_PE_indirect (for global) or DW_EH_PE_datarel (for local), and fixes libgcc so it can find the address of the GOT as the base address for DW_EH_PE_datarel. Complicating matters somewhat, GAS was missing support for %gotoff(symbol) relocation syntax. I have just pushed a fix for that, but I've added a configure check to test for presence of the binutils support and fall back to the current absolute encoding (which works most of the time) if it is not available. Once the fix makes it into an official binutils release it might be appropriate to make this error out instead. Since this is a wrong-code bug and affects only nios2 target, I think this is appropriate for Stage 4. I regression-tested on both nios2-linux-gnu and nios2-elf, with and without the binutils support present, before committing this. 2020-01-31 Sandra Loosemore <sandra@codesourcery.com> gcc/ * configure.ac [nios2-*-*]: Check HAVE_AS_NIOS2_GOTOFF_RELOCATION. * config.in: Regenerated. * configure: Regenerated. * config/nios2/nios2.h (ASM_PREFERRED_EH_DATA_FORMAT): Fix handling for PIC when HAVE_AS_NIOS2_GOTOFF_RELOCATION.

(init_spec): If LINK_EH_SPEC is defined, prepend it to link_spec. * mklibgcc.in: Don't include LIB2ADDEH objects into libgcc.a if creating libgcc_s.so, put them into separate libgcc_eh.a instead. * unwind-dw2-fde.c: Don't include any headers if this file is included from other .c file. * unwind-dw2-fde-glibc.c: New file. * crtstuff.c (USE_PT_GNU_EH_FRAME, USE_EH_FRAME_REGISTRY): Define. Use it instead of EH_FRAME_SECTION_NAME where appropriate. From-SVN: r48039
