This fixes some EH failures for the medany code model in the g++ testsuite. The problem is that the assembler is computing some values in the eh_frame section as constants, that instead should have had relocs to be resolved by the linker. This happens in output_cfi_insn in the DW_CFA_advance_loc case where it compares label frags and immediately simplifies if they are the same. We can fix that by forcing a new frag after every instruction that the linker can reduce in size. I've also added a testcase to verify the fix. This was tested with binutils make check, and gcc/g++ make checks on qemu for medlow and medany code models. gas/ * config/tc-riscv.c (append_insn): Call frag_wane and frag_new at end for linker optimizable relocs. * testsuite/gas/riscv/eh-relocs.d: New. * testsuite/gas/riscv/eh-relocs.s: New. * testsuite/gas/riscv/riscv.exp: Run eh-relocs test. |
