Petr Hosek d56b171ee9 [lld][ELF] Support for R_ARM_THM_JUMP8 
This change implements support for R_ARM_THM_JUMP8 relocation in
addition to R_ARM_THM_JUMP11 which is already supported by LLD.

Igor Kudrin 657e067bb5 [ARMInstPrinter] Print the target address of a branch instruction 
This follows other patches that changed printing immediate values of
branch instructions to target addresses, see D76580 (x86), D76591 (PPC),
D77853 (AArch64).

As observing immediate values might sometimes be useful, they are
printed as comments for branch instructions.

Fangrui Song f0374e7db2 [test] lld/test/: change llvm-objdump single-dash long options to double-dash options 2020-03-15 17:48:36 -07:00
Georgii Rymar e4ceb8f421 [lib/ObjectYAML] - Make `ELFYAML::Relocation::Offset` optional. 
Currently `yaml2obj` require `Offset` field in a relocation description.
There are many cases when `Offset` is insignificant in a context of a test case.

Making `Offset` optional allows to simplify our test cases.
This is what this patch does.

Also, with this patch `obj2yaml` does not dump a zero offset of a relocation.

Fangrui Song 71e2ca6e32 [llvm-objdump] -d: print `00000000 <foo>:` instead of `00000000 foo:` 
The new behavior matches GNU objdump. A pair of angle brackets makes tests slightly easier.

`.foo:` is not unique and thus cannot be used in a `CHECK-LABEL:` directive.
Without `-LABEL`, the CHECK line can match the `Disassembly of section`
line and causes the next `CHECK-NEXT:` to fail.

```
Disassembly of section .foo:

0000000000001634 .foo:
```

Bdragon: <> has metalinguistic connotation. it just "feels right"

Fangrui Song 5387c2cd17 [llvm-objdump] Print newlines before and after "Disassembly of section ...:" 
This improves readability and the behavior is consistent with GNU objdump.

The new test test/tools/llvm-objdump/X86/disassemble-section-name.s
checks we print newlines before and after "Disassembly of section ...:"

Peter Smith 23a116f39e [ELF] Test undefined weak symbol for Thumb narrow branch 
Add a test for the R_ARM_THM_JUMP11 relocation to an undefined symbol. We
have to use yaml2obj as llvm-mc relaxes the narrow branch to a b.w which
uses the R_ARM_THM_JUMP24 relocation instead.
