2019-06-20[llvm-objdump] Switch between ARM/Thumb based on mapping symbols.Eli Friedman1-29/+80
The ARMDisassembler changes allow changing between ARM and Thumb mode based on the MCSubtargetInfo, rather than the Target, which simplifies the other changes a bit. I'm not really happy with adding more target-specific logic to tools/llvm-objdump/, but there isn't any easy way around it: the logic in question specifically applies to disassembling an object file, and that code simply isn't located in lib/Target, at least at the moment.

with --section This fixes PR41886: llvm-objdump -d -r -j .text doesn't show inline relocations of .text While here, switch to stable_sort() because we don't want to change the order of relocations applied to the same location. gABI says consecutive relocation records are composed together and their order matters. In practise it is difficult to see relocations applied to the same location not consecutive, we just have to keep the relative order of relocations with the same offset.

This relands D60376/rL358405, with the difference: sed 'y/\t/ /' -> tr '\t' ' ' BSD sed doesn't support escape characters for the 'y' command. I didn't use it in rL358405 because it was not listed at https://llvm.org/docs/GettingStarted.html#software but it should be available. Original description: In GNU objdump, -w/--wide aligns instructions in the disassembly output. This patch does the same to llvm-objdump. However, we always use the wide format (-w/--wide is ignored), because the narrow format (instructions are misaligned) is probably not very useful. In llvm-readobj, we made a similar decision: always use the wide format, accept but ignore -W/--wide.

2019-02-27[DebugInfo] add SectionedAddress to DebugInfo interfaces.Alexey Lapshin1-23/+27
That patch is the fix for https://bugs.llvm.org/show_bug.cgi?id=40703 "wrong line number info for obj file compiled with -ffunction-sections" bug. The problem happened with only .o files. If object file contains several .text sections then line number information showed incorrectly. The reason for this is that DwarfLineTable could not detect section which corresponds to specified address(because address is the local to the section). And as the result it could not select proper sequence in the line table. The fix is to pass SectionIndex with the address. So that it would be possible to differentiate addresses from various sections. With this fix llvm-objdump shows correct line numbers for disassembled code.

The two implemented options allow selecting register names on ARM: * With -Mreg-names-raw, the disassembler uses rNN for all registers. * With -Mreg-names-std it prints sp, lr and pc for r13, r14 and r15, which is the default behavior of llvm-objdump.
