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 b587ca93be [test] Replace `yaml2obj >` with `yaml2obj -o` and remove unneeded input redirection 2020-08-20 15:01:09 -07:00
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
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 ...:"

Martin Storsjo e2e8e08ec3 Update tests for ARMNT/ARM64 reloc names 
After ObjectYAML learnt the proper enum names for ARMNT/ARM64
relocations, it no longer accepts the numerical values.

This fixes LLD tests after SVN r317459 in LLVM.
