From 41947d9e38c4fd27b17843f328d58138193e4f19 Mon Sep 17 00:00:00 2001 From: "Maciej W. Rozycki" Date: Tue, 21 Jun 2016 21:22:39 +0100 Subject: [PATCH] MIPS/GAS: Handle resolved R6 PC-relative relocations Complement commit 7361da2c952e ("Add support for MIPS R6.") and fix internal errors like: foo.s: Assembler messages: foo.s: Internal error! Assertion failure in md_apply_fix at .../gas/config/tc-mips.c:15028. Please report this bug. triggered by resolved R6 PC-relative relocations in sources containing R6 code fragments wrapped into ISA override blocks embedded within code otherwise assembled for an older ISA. gas/ * config/tc-mips.c (calculate_reloc) : New switch cases. (md_apply_fix) : Move switch cases along `BFD_RELOC_MIPS_JMP'. : Handle the resolved case. * testsuite/gas/mips/pcrel-reloc-4.d: New test. * testsuite/gas/mips/pcrel-reloc-4-r6.d: New test. * testsuite/gas/mips/pcrel-reloc-5.d: New test. * testsuite/gas/mips/pcrel-reloc-5-r6.d: New test. * testsuite/gas/mips/pcrel-reloc-6.d: New test. * testsuite/gas/mips/pcrel-reloc-6.l: New list test. * testsuite/gas/mips/pcrel-reloc-4.s: New test source. * testsuite/gas/mips/pcrel-reloc-6.s: New test source. * testsuite/gas/mips/mips.exp: Run the new tests. --- gas/config/tc-mips.c | 62
