This patch corresponds to r275511 for COFF.

Previously, it checked for the EC parameter and set HasError
only when there was an error. But in most places we called
error only when error had occurred, so this behavior was confusing.

ELF spec says that alignment of 0 is equivalent to 1.
Previously, we arbitrary set to 0 or 1, but always setting to 1
makes our program simpler.

r275301 made .got section be aligned on Target->GotEntrySize,
so GotEntrySize must have been initialized. We didn't initialize
it for AMDGPU.

Patch by H.J Lu.

For x86-64 psABI, the entry size of .got and .got.plt sections is 8
bytes for both LP64 and ILP32.  Add GotEntrySize and GotPltEntrySize
to ELF target instead of using size of ELFT::uint.  Now we can generate
a simple working x32 executable.

This patch renames VAStart ImageBase so that they are in line with

Minor cleanup.
Currently it looks wierd that having method addPredefinedSections()
we still add 2 sections outside it without real reasons.
Patch fixes that.

Patch implements 'extern' version script tag.
Currently only values in quotes(") are supported.

Matching of externs is performed in the same pass as exact match of globals.

* fixed compilation error under linux:

template <class ELFT> class OutputSectionFactory {

  typedef typename SectionKey<ELFT::Is64Bits> Key;

Creating sections on linkerscript side requires some methods
that can be reused if are exported from writer.

Patch implements that change.

Differential revision: http://reviews.llvm.org/D20104

llvm-svn: 275162

Since linkerscript should create sections by itself
(if SECTIONS command is present),
then we might want to reuse the OutputSectionFactory (D19976 already do that now),
so this patch moves it out from writer cpp file for that purpose.

That helps to avoid expressions like I + 2 in code
that assigns version number to symbols.

Only MipsThunk were using the function, and the way how it wrote
thunk contents was different from ARM thunks. This patch makes
them consistent.

Although they are in the same .cpp file, the way they were written
were slightly different, so they looked more different than they were.

Symbol's dtors are not called because they are allocated using
BumpPtrAllocators. So, members of std::unique_ptr type are not
freed when symbols are deallocated.

This patch is to allocate Thunks using BumpPtrAllocators.

llvm-svn: 274896

The TinyPtrVector of const Thunk<ELFT>* in InputSections.h can cause 
build failures on certain compiler/library combinations when Thunk<ELFT> 
is not a complete type or is an abstract class. Fixed by making Thunk<ELFT>
non Abstract.

    Generalise the Mips LA25 Thunk code and implement ARM and Thumb
    interworking Thunks.
    
    - Introduce a new module Thunks.cpp to store the Target Specific Thunk
      implementations.
    - DefinedRegular and Shared have a ThunkData field to record Thunk.
    - A Target can have more than one type of Thunk.
    - Support PC-relative calls to Thunks.
    - Support Thunks to PLT entries.
    - Existing Mips LA25 Thunk code integrated.
    - Support for ARMv7A interworking Thunks.
    
    Limitations:
    - Only one Thunk per SymbolBody, this is sufficient for all currently
      implemented Thunks.
    - ARM thunks assume presence of V6T2 MOVT and MOVW instructions.

  When building executable usually version script is absent.
Before this patch error was shown in the case when
symbol name contained version and there was no script to match it.
  Instead of error out patch allows
to create new version declaration in this case and use it.
gnu linkers do the same.

That is PR28359.
