Maciej W. Rozycki 88a7ef1689 MIPS16/GAS: Restore unsupported relocation diagnostics ... Correct a MIPS16 relocation handling regression in GAS introduced with: commit 177b4a6ad0 Author: Alexandre Oliva <aoliva@redhat.com> Date: Mon Mar 18 18:56:18 2002 +0000 discussed at <https://sourceware.org/ml/binutils/2002-03/msg00345.html>, which removed a preparatory call to `mips16_extended_frag' previously made from `md_estimate_size_before_relax'. As a result the function is never called with its `sec' parameter non-NULL and consequently all the unsupported relocation checks within are dead and never trigger, causing any unhandled relocations to silently resolve to 0. Unfortunately there was no sufficient test suite coverage back then to catch this. Remove all dead code then, and all the associated comments. Update the remaining call to `mips16_extended_frag' from `mips_relax_frag' to pass the relocation section as the `sec' parameter and use it to mark frags which require an external relocation, as extended. Finally handle any outstanding MIPS16 relocations in `md_convert_frag' and report an error since we don't support any except with percent operators. gas/ * config/tc-mips.c (append_insn): Use any `O_symbol' expression unchanged with relaxed MIPS16 instructions. (mips16_extended_frag): Adjust accordingly. Return 1 right away if a relocation will be required for the symbol requested. Remove dead first relaxation pass code. (mips_relax_frag): Pass `sec' down to `mips16_extended_frag'. (md_convert_frag): Adjust symbol value calculation. Raise an error if a relocation is required for the symbol requested. * testsuite/gas/mips/mips16@relax-swap3.d: Remove dump patterns, add error output. * testsuite/gas/mips/mips16@relax-swap3.l: New error output. * testsuite/gas/mips/mips16-pcrel-relax-0.d: New test. * testsuite/gas/mips/mips16-pcrel-relax-1.d: New test. * testsuite/gas/mips/mips16-pcrel-relax-2.d: New test. * testsuite/gas/mips/mips16-pcrel-relax-3.d: New test. * testsuite/gas/mips/mips16-pcrel-reloc-0.d: New test. * testsuite/gas/mips/mips16-pcrel-reloc-1.d: New test. * testsuite/gas/mips/mips16-pcrel-reloc-2.d: New test. * testsuite/gas/mips/mips16-pcrel-reloc-3.d: New test. * testsuite/gas/mips/mips16-pcrel-reloc-4.d: New test. * testsuite/gas/mips/mips16-pcrel-reloc-5.d: New test. * testsuite/gas/mips/mips16-pcrel-reloc-6.d: New test. * testsuite/gas/mips/mips16-pcrel-reloc-7.d: New test. * testsuite/gas/mips/mips16-pcrel-addend-0.d: New test. * testsuite/gas/mips/mips16-pcrel-addend-1.d: New test. * testsuite/gas/mips/mips16-pcrel-addend-2.d: New test. * testsuite/gas/mips/mips16-pcrel-addend-3.d: New test. * testsuite/gas/mips/mips16-pcrel-absolute.d: New test. * testsuite/gas/mips/mips16-branch-reloc-0.d: New test. * testsuite/gas/mips/mips16-branch-reloc-1.d: New test. * testsuite/gas/mips/mips16-branch-reloc-2.d: New test. * testsuite/gas/mips/mips16-branch-reloc-3.d: New test. * testsuite/gas/mips/mips16-branch-addend-0.d: New test. * testsuite/gas/mips/mips16-branch-addend-1.d: New test. * testsuite/gas/mips/mips16-branch-addend-2.d: New test. * testsuite/gas/mips/mips16-branch-addend-3.d: New test. * testsuite/gas/mips/mips16-branch-absolute.d: New test. * testsuite/gas/mips/mips16-absolute-reloc-0.d: New test. * testsuite/gas/mips/mips16-absolute-reloc-1.d: New test. * testsuite/gas/mips/mips16-absolute-reloc-2.d: New test. * testsuite/gas/mips/mips16-absolute-reloc-3.d: New test. * testsuite/gas/mips/mips16-pcrel-reloc-2.l: New error output. * testsuite/gas/mips/mips16-pcrel-reloc-3.l: New error output. * testsuite/gas/mips/mips16-pcrel-reloc-6.l: New error output. * testsuite/gas/mips/mips16-pcrel-reloc-7.l: New error output. * testsuite/gas/mips/mips16-pcrel-addend-2.l: New error output. * testsuite/gas/mips/mips16-pcrel-addend-3.l: New error output. * testsuite/gas/mips/mips16-pcrel-absolute.l: New error output. * testsuite/gas/mips/mips16-branch-reloc-2.l: New error output. * testsuite/gas/mips/mips16-branch-reloc-3.l: New error output. * testsuite/gas/mips/mips16-branch-addend-2.l: New error output. * testsuite/gas/mips/mips16-branch-addend-3.l: New error output. * testsuite/gas/mips/mips16-branch-absolute.l: New error output. * testsuite/gas/mips/mips16-absolute-reloc-2.l: New error output. * testsuite/gas/mips/mips16-absolute-reloc-3.l: New error output. * testsuite/gas/mips/mips16-pcrel-relax-0.s: New test source. * testsuite/gas/mips/mips16-pcrel-relax-2.s: New test source. * testsuite/gas/mips/mips16-pcrel-reloc-0.s: New test source. * testsuite/gas/mips/mips16-pcrel-reloc-1.s: New test source. * testsuite/gas/mips/mips16-pcrel-reloc-2.s: New test source. * testsuite/gas/mips/mips16-pcrel-reloc-3.s: New test source. * testsuite/gas/mips/mips16-pcrel-reloc-4.s: New test source. * testsuite/gas/mips/mips16-pcrel-reloc-5.s: New test source. * testsuite/gas/mips/mips16-pcrel-reloc-6.s: New test source. * testsuite/gas/mips/mips16-pcrel-reloc-7.s: New test source. * testsuite/gas/mips/mips16-pcrel-addend-0.s: New test source. * testsuite/gas/mips/mips16-pcrel-addend-1.s: New test source. * testsuite/gas/mips/mips16-pcrel-addend-2.s: New test source. * testsuite/gas/mips/mips16-pcrel-addend-3.s: New test source. * testsuite/gas/mips/mips16-pcrel-absolute.s: New test source. * testsuite/gas/mips/mips16-branch-reloc-0.s: New test source. * testsuite/gas/mips/mips16-branch-reloc-1.s: New test source. * testsuite/gas/mips/mips16-branch-reloc-2.s: New test source. * testsuite/gas/mips/mips16-branch-reloc-3.s: New test source. * testsuite/gas/mips/mips16-branch-addend-0.s: New test source. * testsuite/gas/mips/mips16-branch-addend-1.s: New test source. * testsuite/gas/mips/mips16-branch-addend-2.s: New test source. * testsuite/gas/mips/mips16-branch-addend-3.s: New test source. * testsuite/gas/mips/mips16-branch-absolute.s: New test source. * testsuite/gas/mips/mips16-absolute-reloc-0.s: New test source. * testsuite/gas/mips/mips16-absolute-reloc-1.s: New test source. * testsuite/gas/mips/mips16-absolute-reloc-2.s: New test source. * testsuite/gas/mips/mips16-absolute-reloc-3.s: New test source. * testsuite/gas/mips/mips.exp: Run the new tests.		2016-06-25 00:54:59 +01:00
