7c3ff2eb58 Only process commands in a ONLY_IF_RO if it matches.
This matches bfd behavior. It also makes future changes simpler as we
don't have to worry about ignoring these commands in multiple places

be394db376 [ELF] - Implemented --sort-section cmd line option and SORT_NONE script command.
This fixes Bug 30385 - SORT_NONE not implemented,

`SORT_NONE' disables section sorting by ignoring the command line
section sorting option.

That is why this patch also implements --sort-section option.

eb2246365b Install libLLVM if needed with LLVM_INSTALL_TOOLCHAIN_ONLY
Summary:
When LLVM_LINK_LLVM_DYLIB is set, the libLLVM shared
library needs to be installed in the toolchain.  Without
this chanage LLVM_INSTALL_TOOLCHAIN_ONLY combined with
LLVM_LINK_LLVM_DYLIB results in a broken install.

2364748a49 Defer asm errors to post-statement failure
Recommitting after fixing AsmParser initialization and X86 inline asm
error cleanup.

Allow errors to be deferred and emitted as part of clean up to simplify
and shorten Assembly parser code. This will allow error messages to be
emitted in helper functions and be modified by the caller which has
better context.

As part of this many minor cleanups to the Parser:

* Unify parser cleanup on error
* Add Workaround for incorrect return values in ParseDirective instances
* Tighten checks on error-signifying return values for parser functions
  and fix in-tree TargetParsers to be more consistent with the changes.
* Fix AArch64 test cases checking for spurious error messages that are
  now fixed.

These changes should be backwards compatible with current Target Parsers
so long as the error status are correctly returned in appropriate
functions.

395281cfc3 Recommit r281721 "[ELF] - Linkerscript: implement EXCLUDE_FILE in the middle of a input section description."
With fix for 2 bots. Details about the fix performed is on a review page.

Initial commit message:
This is PR30387:

From PR description:
We fail to parse

SECTIONS
{
  foo :
  {
    *(sec0 EXCLUDE_FILE (zed1.o) sec1  EXCLUDE_FILE (zed2.o) sec2 )
  }
}
The semantics according to bfd are:

Include sec1 from every file but zed1.o
Include sec2 from every file but zed2.o
Include sec0 from every file

Patch implements the support.

d31907957a Change how we compute offsets with linker scripts.
This fixes pr30367, but more importantly, it changes how we compute offsets.

Now offset computation in a walk over linker script commands, like the
rest of assignAddresses. IMHO this is simpler to understand and if we
ever have to create multiple outputsections or chunks to change how we
handle test/ELF/linkerscript/alternate-sections.s it should be easier
to do it.

830a8c1fbd Place the lowered phi instruction(s) before the DEBUG_VALUE entry
When a phi node is finally lowered to a machine instruction it is
important that the lowered "load" instruction is placed before the
associated DEBUG_VALUE entry describing the value loaded.

Renamed the existing SkipPHIsAndLabels to SkipPHIsLabelsAndDebug to
more fully describe that it also skips debug entries. Then used the
"new" function SkipPHIsAndLabels when the debug information should not
be skipped when placing the lowered "load" instructions so that it is
placed before the debug entries.

8dd61aee30 [LTO] Fix handling of mixed (regular and thin) mode LTO
Summary:
In runThinLTO we start the task numbering for ThinLTO backend
tasks depending on whether there was also a regular LTO object
(CombinedModule). However, the CombinedModule is moved at
the end of runRegularLTO, so we need to save this information and
pass it into runThinLTO. Otherwise the AddOutput callback to the client
will use the same task number for both the regular LTO object
and the first ThinLTO object, which in gold-plugin caused only
one to be end up in the output filename array and therefore passed
back to gold for the final native link.
