Feature is used for producing static-linked PIE executables
(https://gcc.gnu.org/ml/gcc/2015-06/msg00008.html)
And was implemented in GNU ld https://gcc.gnu.org/ml/gcc/2015-08/msg00099.html

I also found it in linux kernel build system,
though I think that x86/x64 bootloader does not really rely on it.
Seems it used for PPC though.

Looks like it is not allowed to have an .rst file in this directory
that does not belong to a document tree. I don't know why. This patch
adds a file back to fix a bot.

C++11.rst is removed because LLD now follows the usual coding style
of the LLVM project.

__ehdr_start should be pointing to ELF file headers, not program
headers.

This is a reland of D30319.

With this we complete the transition out of special output sections,
and with the previous patches it should be possible to merge
OutputSectionBase and OuputSection.

llvm-svn: 296023

With the current design an InputSection is basically anything that
goes directly in a OutputSection. That includes plain input section
but also synthetic sections, so this should probably not be a
template.

For functions the linker uses a related hack: creating a plt in the
main executable that preempts the function.

Like bfd and gold, we don't disable it with nocopyreloc.

If -z stack-size is given, we need to add PT_GNU_STACK even if
-z execstack is not given.

We have InputSection, MergeInputSection and EhInputSection, so
isa<MergeInputSection> is equivalent to !isa<InputSection> && !isa<
EhInputSection>.

We shouldn't report an error for R_*_NONE relocs since we're emitting
them when writing relocations to discarded sections.

Now that InputSectionBase is not a template there is no reason to have
the two.

llvm-svn: 295924

Removing this template is not a big win by itself, but opens the way
for removing more templates.

Previously, bitcode files in library paths were passed to the MSVC linker.
This patch strips them.

* Added comment.
* Pass std::string copy instead using move semantic.

I really do not understand what is going on on some Windows buildbots,
but FileCheck command on some buildbot behaves like long lines were
truncated. I'll try to find a cause of the issue, but let me relax the
test so that they'll succeed on all buildbots.
