[MIPS] When calculating a relocation using an undefined weak symbol don't check for overflow. In MIPS the relocation calculation only ignores the overflow checks for undefined weak symbols on relocations associated with j/jal. This patch extends this to the relocations used by the: b* instructions; pc/gp relative symbol offsets; and the lwpc/ldpc MIPS r6 instructions. bfd/ * elfxx-mips.c (mips_elf_calculate_relocation): Only check for overflow on non-weak undefined symbols. ld/testsuite/ * ld-mips-elf/mips-elf.exp: Add in undefined weak overflow tests for o32, n32 and n64. * ld-mips-elf/undefweak-overflow.s: New test. * ld-mips-elf/undefweak-overflow.d: New test. * ld-mips-elf/undefweak-overflow-n32.d: New test. * ld-mips-elf/undefweak-overflow-n64.d: New test.

#name: undefined weak symbol overflow
#source: undefweak-overflow.s
Fix undefined weak symbol reloc tests ld/testsuite/ * ld-mips-elf/mips-elf.exp: Update undefweak-overflow tests. * ld-mips-elf/undefweak-overflow-n32.d: Remove. * ld-mips-elf/undefweak-overflow-n64.d: Likewise. * ld-mips-elf/undefweak-overflow.s: Set mips64r6, noreorder and add a label to mark the micromips region. * ld-mips-elf/undefweak-overflow.d: Update expected output.
