[llvm-readelf][llvm-readobj] - Fix the indentation when printing dynamic tags.

[grimar]

Summary

This change is similar to one made for llvm-objdump in D72838.

llvm-readelf/llvm-readobj tools do not align the "Name/Value" column properly.
This patch adds a logic to calculate the size of indentation on fly
to fix such issues.

In both cases, I'm struggling to follow why specific numbers are used, e.g. where does the "-1" "-3" etc come from?

llvm/test/tools/llvm-readobj/ELF/dynamic-tags.test

585

"this" would be more natural than "that" here.

589

IDENT -> INDENT here and below.

llvm/tools/llvm-readobj/ELFDumper.cpp

5804

Don't know if it really matters, but shouldn't one of these strings be converted to a Twine?

These numbers depends on a column names used.
Imagine we have two cases. In the first, column names are
"Type" and "Value" vs "FooType" and "Value" for the second case.

The number of indentation whitespaces would be different for these cases,
just because "FooType" is 3 characters longer.

In this patch, LLVM style-part uses
"Type" << std::string(MaxTagSize - 3, ' ') << "Name/Value\n";.

The indentation we want to print is MaxTagSize - 3 because it is ==
[MaxTagSize - the length of Type (4) + a single trailing whitespace (1)].

For the GNU style I've used -1 because it wraps tag names into '(`, ')', e.g:

Tag        Type                   Name/Value
0x00000001 (NEEDED)               Shared library: [D]

Hence the indentation length is increased by 2 because of 2 round brackets printed additionally.

Right, I figured it was something like that. Is there any chance of pulling the column header names into separate individual string literals, so that you can do things like sizeof(NameValueStr) or whatever. I'd recommend adding code comments where that is not practical.

• Addressed review comments.

It would be
(Twine("%-") + std::to_string(MaxTagSize) + "s ").str();
I think the complexity added does not worth it?

[jhenderson]

LGTM with a couple of nits.

llvm/tools/llvm-readobj/ELFDumper.cpp

4000

whitespaces -> spaces

4001

whitespace -> space
