Error was:

Alternative approach can be remove templated method
either, like D31028 do.

llvm-svn: 298065

Was fixed, details on review page.

Original commit message:

That removes CopyRelSection class completely, making
Bss/BssRelRo to be just regular synthetics.

This is splitted from D30541 and polished.
Difference from D30541 that all logic of SharedSymbol
converting to DefinedRegular was removed for now and
probably will be posted as separate patch.

That opens road to detemplate PltSection<ELFT>,
what allows then to detemplate all methods of SymbolBody.

Being passed -z notext is a pretty strong indication that the user is
OK with text relocations. This is not the same behavior as bfd, but
bfd defaults to -z notext, so it has to try to avoid text relocations
and use them as a last resort.

llvm-svn: 297789

gold linker manual describes them as:

-z text	Do not permit relocations in read-only segments
-z notext Permit relocations in read-only segments (default)

In LLD default is to not permit them. Patch implements -z notext.

This reverts commit r297008 because it's reported that that
change broke AArch64 bots.

This change moves the calls to finalizeContent() for each synthetic section
before createThunks(). This will allow us to assign addresses prior to
calling createThunks(). As addition of thunks may add to the static
symbol table and may affect the size of the mips got section we introduce a
couple of additional member functions to update these values.

This change fixes a bug in which the Mips LA25 Thunks are always assigned
to the same Output section as the caller and not the callee as expected.

In compare with D30458, this makes Bss/BssRelRo to be pure
synthetic sections.

That removes CopyRelSection class completely, making
Bss/BssRelRo to be just regular synthetics.

SharedSymbols involved in creating copy relocations are
converted to DefinedRegular, what also simplifies things.

In many places we reset Size to 0 before calling assignOffsets()
manually. Sometimes we don't do that. 
It looks we can just always do that inside.

Previous code had:
template <class ELFT> void OutputSection::assignOffsets() {
  uint64_t Off = Size;

And tests feels fine with Off = 0. 
I think Off = Size make no sence.

Now that all special sections are SyntheticSections, we only need one
OutputSection class.

llvm-svn: 296127

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.

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

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

have the same option.

The previous name caused a little confusion because the function not
only returns aliases but a given symbol itself too.

This patch removes NeedsCopyOrPltAddr and instead add two variables,
NeedsCopy and NeedsPltAddr. This uses one more bit in Symbol class,
but the actual size doesn't increase because we had unused bits.
This should improve code readability.

llvm-svn: 295287

This is slightly inefficient than the previous code, but that is really
negligible as this function is usually called at most only a few times.

llvm-svn: 295282

Previously, space in a BSS section for copy relocations are reserved
in a special way. We directly manipulated size of the BSS section.
r294577 changed the way of doing it. Now, we create an instance of
CopyRelSection (which is a synthetic input section) for each copy
relocation.

This patch removes the remains of the old way and add CopyRelSections
to BSS sections using `addSections` function, which is the usual
way to add an input section to an output section.

llvm-svn: 295278

In the target dependent code we already always return a int64_t. In
the target independent code we carefully use uintX_t, which has the
same result given 2 complement rules.

This just simplifies the code to use int64_t everywhere.
