MIPS/BFD: Fix section symbol name fetching in relocation Symbol table entries for section symbols are different between IRIX and traditional MIPS ELF targets in that IRIX entries have their `st_name' member pointing at the section's name in the string table section, while traditional entries have 0 there and the section header string table has to be referred via the relevant section header's `shn_name' member instead. This is chosen with the `elf_backend_name_local_section_symbols' backend and can be observed with `readelf -s' output for an IRIX object: Symbol table '.symtab' contains 12 entries: Num: Value Size Type Bind Vis Ndx Name 0: 00000000 0 NOTYPE LOCAL DEFAULT UND 1: 00000000 0 SECTION LOCAL DEFAULT 1 .text 2: 00000000 0 SECTION LOCAL DEFAULT 3 .data 3: 00000000 0 SECTION LOCAL DEFAULT 4 .bss 4: 00000000 0 SECTION LOCAL DEFAULT 5 .reginfo 5: 00000000 0 SECTION LOCAL DEFAULT 6 .MIPS.abiflags 6: 00000000 0 SECTION LOCAL DEFAULT 7 .pdr 7: 00000000 0 SECTION LOCAL DEFAULT 9 .gnu.attributes 8: 00002000 16 FUNC GLOBAL DEFAULT 1 foo 9: 00004008 0 FUNC LOCAL DEFAULT 1 abar 10: 00002008 0 FUNC LOCAL DEFAULT 1 afoo 11: 00004000 16 FUNC GLOBAL DEFAULT 1 bar and a corresponding traditional object: Symbol table '.symtab' contains 12 entries: Num: Value Size Type Bind Vis Ndx Name 0: 00000000 0 NOTYPE LOCAL DEFAULT UND 1: 00000000 0 SECTION LOCAL DEFAULT 1 2: 00000000 0 SECTION LOCAL DEFAULT 3 3: 00000000 0 SECTION LOCAL DEFAULT 4 4: 00004008 0 FUNC LOCAL DEFAULT 1 abar 5: 00002008 0 FUNC LOCAL DEFAULT 1 afoo 6: 00000000 0 SECTION LOCAL DEFAULT 5 7: 00000000 0 SECTION LOCAL DEFAULT 6 8: 00000000 0 SECTION LOCAL DEFAULT 7 9: 00000000 0 SECTION LOCAL DEFAULT 9 10: 00002000 16 FUNC GLOBAL DEFAULT 1 foo 11: 00004000 16 FUNC GLOBAL DEFAULT 1 bar respectively. Consequently the right way to retrieve a section symbol's name has to be chosen in `mips_elf_calculate_relocation' for the purpose of error reporting. Originally we produced symbol tables in the traditional object format only and we handled it correctly until it was lost in a rewrite with: commit 7403cb6305f5660fccc8869d3333a731102ae978 Author: Mark Mitchell <mark@codesourcery.com> Date: Wed Jun 30 20:13:43 1999 +0000 probably because of the extra pointer indirection added which made the same expression have a different meaning. With the addition of IRIX symbol table format with: commit 174fd7f9556183397625dbfa99ef68ecd325c74b Author: Richard Sandiford <rdsandiford@googlemail.com> Date: Mon Feb 9 08:04:00 2004 +0000 the bug has been partially covered and now when a relocation error is triggered with an IRIX object the offending section symbol is correctly reported: tmpdir/dump0.o: In function `foo': (.text+0x2000): relocation truncated to fit: R_MIPS_26 against `.text' tmpdir/dump0.o: In function `bar': (.text+0x4000): relocation truncated to fit: R_MIPS_26 against `.text' because `bfd_elf_string_from_elf_section' retrieves the name from the string table section. With a traditional object however the function returns an empty string and consequently `no symbol' is printed instead: tmpdir/dump0.o: In function `foo': (.text+0x2000): relocation truncated to fit: R_MIPS_26 against `no symbol' tmpdir/dump0.o: In function `bar': (.text+0x4000): relocation truncated to fit: R_MIPS_26 against `no symbol' Restore the original semantics so that the section name is always correctly retrieved. bfd/ * elfxx-mips.c (mips_elf_calculate_relocation): Also use the section name if `bfd_elf_string_from_elf_section' returns an empty string. ld/ * testsuite/ld-mips-elf/reloc-local-overflow.d: New test. * testsuite/ld-mips-elf/reloc-local-overflow.s: Source for the new test. * testsuite/ld-mips-elf/mips-elf.exp: Run the new test.

MIPS/LD/testsuite: Correct mips-elf.exp test ABI/emul/endian arrangement Similarly to commit 86b24e15c45b ("MIPS/LD/testsuite: Correct comm-data.exp test ABI/emul/endian arrangement") update the mips-elf.exp test script to: - correctly select emulations for targets using non-traditional MIPS emulations, - correctly select ABIs for targets that do not support all of them, - use the default endianness selection where possible to benefit targets that support only one, - simplify test invocation by providing ABI-specific `run_dump_test' wrappers, specifically `run_dump_test_o32', `run_dump_test_n32', `run_dump_test_n64' and `run_dump_test_eabi', which remove the need to use conditionals across the Expect script or to repeat ABI-specific GAS and LD flags with each invocation, removing numerous test failures for `mips-sgi-irix6', `mips64-openbsd', `mips64el-openbsd' and `mips64el-ps2-elf' targets and broadening coverage for several MIPS targets. There are some new failures for the `mips64el-ps2-elf' target with tests that were not previously run for that target: FAIL: MIPS16 link branch to absolute expression (n32) FAIL: MIPS16 link branch to absolute expression 1 (n32) FAIL: MIPS16 link branch to absolute expression 2 (n32) FAIL: microMIPS link branch to absolute expression (n32) FAIL: MIPS ELF got reloc n32 FAIL: MIPS ELF xgot reloc n32 FAIL: undefined weak symbol overflow (n32) FAIL: R_MIPS16_HI16 and R_MIPS16_LO16 relocs n32 FAIL: ld-mips-elf/attr-gnu-4-0-n32-ph FAIL: ld-mips-elf/attr-gnu-4-1-n32-ph FAIL: ld-mips-elf/attr-gnu-4-2-n32-ph FAIL: ld-mips-elf/attr-gnu-4-3-n32-ph FAIL: MIPSr6 JALR reloc unaligned/cross-mode link test (n32) which are mostly due to dump discrepancies caused by mapping differences coming from the default linker scripts used by these test cases, or sometimes because of the specific MIPS processor architecture recorded in the ELF file taking precedence over the general MIPS ISA level also recorded. Finally, the R_MIPS16_HI16/R_MIPS16_LO16 relocation test failure is a preexisting issue with the IRIX style emulation. These failures will have to be addressed separately. ld/ * testsuite/ld-mips-elf/mips-elf.exp (run_dump_test_abi) (run_dump_test_o32, run_dump_test_n32, run_dump_test_n64) (run_dump_test_eabi): New procedures.
