This is the initial straight rename commit. It will probably break the
docs build, but it has to be a separate PR for blame preservation
purposes.

[docs] Finish MyST migration for BOLT docs (#210199)

Tracking issue: #201242
See the [migration guide] for more information.

This is a stacked PR based on #210198, which will be a standalone commit
that
renames *.rst -> *.md before this PR lands for history preservation
purposes.

This was prepared with rst2myst plus LLM-assisted cleanup. I paged
through all the generated HTML looking for migration artifacts, and all
of the differences I could find appear to be formatting error
corrections. Please spot check my work and approve if it looks good. You
can use the HTML links below to confirm it renders properly.

Git commit 611d015f0030e0d4f1b3bd2270205f6f6b6e20eb by GitHub (on behalf of Peter Collingbourne) on 17/07/2026 at 00:03..
gn build: Support building debug binaries from a release build directory.

This change makes it so that all binaries in `bin` have a corresponding
debug binary target `$TARGET.dbg` that will build a debug binary in
`bin.dbg/$TARGET`. This is implemented using a separate toolchain for
the debug builds. This has the following advantages over a separate
debug build directory:

1. Can use release mode tblgen to generate code for the debug build
   binaries, which speeds up the build because it can run tblgen faster as
   well as being able to reuse the tblgen binary from the release build.

2. Can reuse runtimes built in the release mode clang's resource
   directory, avoiding the need to build them again with a slow debug
   build of clang.

[libc][math] Fix double-rounding errors with denormal inputs for hypot function. (#208247)

The issue was reported by Paul Zimmermann.

Solution: for denormal inputs, we use 1.0 + x trick after proper scaling
to mimick rounding at denormal scale.

[orc-rt] Add asCCallback utility -- C callbacks for methods. (#210048)

Adds orc_rt::asCCallback<&Class::method>, which produces a C-ABI
function pointer that forwards to the given member function. The first
parameter of the generated trampoline is an opaque context pointer (
void * for non-const methods, const void * for const methods) that is
cast back to the class type and used as the receiver:

  struct Counter {
    void inc(int N) { Count += N; }
    int Count = 0;
  };

  Counter C;
  void (*CB)(void *, int) = asCCallback<&Counter::inc>;
  CB(asCCallbackContext<&Counter::inc>(C), 2); // C.Count == 2

asCCallbackContext produces the matching context pointer via
static_cast, so any base-class offset is applied and const-ness is
preserved; pairing it with asCCallback by the same method keeps things
correct under inheritance and const-qualification. (A raw cast of &C
would give the trampoline the wrong `this` when method's class is a base
at a non-zero offset.)

Specializations cover the const x noexcept combinations. The trampoline
is always noexcept -- a C caller cannot unwind a C++ exception, so an
escaping one terminates -- and return/argument types are restricted to
C-compatible (non-reference, trivially copyable) types via
static_assert.

[BOLT] Add fdata symbols mode (#209932)

Add a new fdata profile mode accepting symbol names as-is.

It addresses the UX gap surfaced by #208313 that all methods of selecting
functions to process (symbolized profile types, `-funcs*` options) expect
disambiguated local symbols. 

Introduce fdata mode activated by a `symbols` header line, where each subsequent
line is a (mangled) symbol name. The names are matched against restored function
names (with disambiguation suffix stripped), and every matching function gets an
execution count of 1. 

This can be used to drive selective instrumentation (`--instrument-hot-only`) or
basic linker-script style optimizations.

Symbols are stored as branch entry data so matching reuses the existing default
branch profile path.

Test Plan:
Update docs/profiles.md and add profile-symbols-mode.s

[clang][ssaf] Add static-library create subcommand (#208799)

This change adds `clang-ssaf-linker static-library create` for bundling
TU summaries into a StaticLibrary archive. The linker has been
refactored to dispatch on `cl::SubCommand`; invocations without a
subcommand still run the existing linker pipeline unchanged for backward
compatibility.

[lldb/script] Migrate frame recognizers onto ScriptedPythonInterface  (#209805)

Give `frame recognizer add -l` a formal
ScriptedStackFrameRecognizerInterface, matching the architecture already
used by ScriptedProcess, ScriptedBreakpoint, etc.: a C++ interface
header, a Python-backed implementation built on
ScriptedPythonInterface's CreatePluginObject/Dispatch machinery,
PluginManager registration, and a generatable Python ABC template
(scripted_stackframe_recognizer.py).

get_recognized_arguments' documented contract returns a plain list of
lldb.SBValue (not an lldb.SBValueList), so it bypasses the generic
Dispatch<ValueObjectListSP>() extractor and calls the SWIG bridge
directly, matching the legacy behavior exactly.

ScriptedStackFrameRecognizer now holds a single interface object created
once in its constructor and reused across every RecognizeFrame() call,
same lifecycle as before.

Add expression validation tests for DW_OP_swap (#210184)

Add DIExpression validation tests for DW_OP_swap that we noticed were
missing. The tests are based on the existing expression tests for
DW_OP_stack_value.

Tested via make check.
