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.

MIPS16/GAS: Fix absolute references with PC-relative synthetic instructions
...
Complement commit 88a7ef168927 ("MIPS16/GAS: Restore unsupported
relocation diagnostics") and also propagate constant expressions, either
already reduced from absolute symbol references or created from literals
in the first place, used as a PC-relative operand with the MIPS16 LA,
LW, DLA and LD synthetic instructions to relaxation, matching the way
forward absolute symbol references have been handled as from the commit
referred and letting relaxation produce any necessary relocations, if
possible, for the absolute value requested to be reproduced at the run
time.
Call `symbol_append' for any expression symbol created for the purpose
of MIPS16 relaxation as with constant expressions now propagated from
earlier on such symbols may make it through and have R_MIPS16_PC16_S1
relocations emitted against, and therefore need to appear in the symbol
table produced.
