MIPS/BFD: Correctly report unsupported `.reginfo' section size
Report an error when an unsupported `.reginfo' section size is found in
`_bfd_mips_elf_section_processing', removing an assertion that triggers
at elfxx-mips.c:7105 in GAS when assembling input like:
.section .reginfo
.word 0xdeadbeef
and in `objcopy --rename-section' when renaming an incorrectly sized
section to `.reginfo'.
bfd/
* elfxx-mips.c (_bfd_mips_elf_section_processing): For
SHT_MIPS_REGINFO sections don't assert the correct size and
report an error instead.
binutils/
* testsuite/binutils-all/mips/mips-reginfo.d: New test.
* testsuite/binutils-all/mips/mips-reginfo-n32.d: New test.
* testsuite/binutils-all/mips/mips-reginfo.s: New test source.
* testsuite/binutils-all/mips/mips.exp: Run the new tests.
gas/
* testsuite/gas/mips/reginfo-2.d: New test.
* testsuite/gas/mips/reginfo-2-n32.d: New test.
* testsuite/gas/mips/reginfo-2.l: New test stderr output.
* testsuite/gas/mips/reginfo-2.s: New test source.
* testsuite/gas/mips/mips.exp: Run the new tests.
