This is the only legitimate use we currently have for modifying
a CompletionRequest. Add a utility function for this purpose
and remove the remaining setters which go against the idea of

This is a follow-up for D67757,
which allows to describe .stack_sizes sections with a new
YAML syntax.

Currently we can't use unique suffixes in section names to describe
stack sizes sections. E.g. '.stack_sizes [1]' will be treated as a regular section.
This happens because we recognize stack sizes section by name and
do not yet drop the suffix before the check.
The patch fixes it.

The cursor position is always at the end of the current argument (as the
argument cut off after the cursor position). So this code is a no-op and

ld64 in the macOS 10.15 SDK gives __DATA a maxprot of 3, meaning it
can't be made executable at runtime by default.
Change clear_cache_test.c to use mmap()ed data that's mapped as writable
and executable from the beginning, instead of trying to mprotect()ing a
__DATA variable as executable. This fixes the test on macOS with the
10.15 SDK.

This work-around was necessary to handle standard library headers in

During legalisation we can end up with some pretty strange nodes, like shifts
of 0. We need to make sure we don't try to make long shifts of these, ending up
with invalid assembly instructions. A long shift with a zero immediate actually
encodes a shift by 32.

The crash might happen when we have either a broken or unsupported object
and trying to resolve relocations when dumping the .stack_sizes section.
For the test case I used a 32-bits ELF header and a 64-bit relocation.
In this case a null pointer is returned by the code instead of the relocation
resolver function and then we crash.

Fix installing Python modules on systems that use /usr/lib for Python
while installing other libraries in /usr/lib64. Rewrite CMake logic
to query correct directories from Python, similarly to how
prepare_binding_Python.py does it. Furthermore, change the regex used
in get_relative_lib_dir.py to allow 'lib' without suffix.
I think that the code can be further improved but I'd like to take
this enterprise in smaller steps in case one of them breaks something.

That flag was introduced in Clang 6.0, so this made the test fail
with Clang <= 5.0. As it only influences linking builtin libraries
like -m which aren't relevant for this test, we can drop this flag.

I think we should be able to use shl instead of sshl and ushl for
positive constant shift values, unless I am missing something.
We already have the machinery in place to ensure we only replace
nodes, if the shift value is positive and <= the element width.
This is a generalization of an earlier patch rL372565.

D64906 allows PT_LOAD to have overlapping p_offset ranges. In the
default R RX RW RW layout + -z noseparate-code case, we do not tail pad
segments when transiting to another segment. This can save at most
3*maxPageSize bytes.
a) Before D64906, we tail pad R, RX and the first RW.
b) With -z separate-code, we tail pad R and RX, but not the first RW (RELRO).
In some cases, b) saves one file page. In some cases, b) wastes one
virtual memory page. The waste is a concern on Fuchsia. Because it uses
compressed binaries, it doesn't benefit from the saved file page.
This patch adds -z separate-loadable-segments to restore the behavior before
D64906. It can affect section addresses and can thus be used as a
debugging mechanism (see PR43214 and ld.so partition bug in
crbug.com/998712).

Summary:
When support for ThinLTO was first added to lld, the options that
control it were prefixed with --plugin-opt= for compatibility with
an existing implementation as a linker plugin. This change enables
shorter versions of the options to be used, as follows:
New Existing
-thinlto-emit-imports-files --plugin-opt=thinlto-emit-imports-files
-thinlto-index-only --plugin-opt=thinlto-index-only
-thinlto-index-only= --plugin-opt=thinlto-index-only=
-thinlto-object-suffix-replace= --plugin-opt=thinlto-object-suffix-replace=
-thinlto-prefix-replace= --plugin-opt=thinlto-prefix-replace=
-lto-obj-path= --plugin-opt=obj-path=
The options with the --plugin-opt= prefix have been retained as aliases
for the shorter variants so that they continue to be accepted.
