+
+When developers use noinline attribute with a function, i.e., through use of
+``__attribute__((noinline))``, they are trying to communicate that the
+function should not be inlined by the compiler. These can be due to various
+number of reasons to mark a function noinline. If a function is small,
+not critical to the performance of your code and would be called less often,
+especially in cases of error handling, it makes sense to noinline a function.
+These annotations, however, can be incorrect for a variety of reasons:
+changes to the code base may make these functions hot, the developer
+mis-annotated them, or perhaps they assumed something incorrectly when they
+wrote the annotation. Regardless of why, it is useful to detect these
+situations so that the user can rethink and remove the attribute as necessary.
+
+MisNoInline diagnostics are intended to help developers identify and address
+these situations, by comparing function hotness of noinline function and
+checking if they indeed were candidates to become inline. Whenever percentile values
+are breached, a warning is emitted from backend. Details on how the flags operate
+in the LLVM backed can be found in LLVM's documentation.
+
+By default, MisNoInline checking is quite linient. It checks on default threshold percentile
+of 99%. Because this may emit a lot of warnings, MisNoInline diagnostics are not enabled by
+default, and support an additional flag to decrease the noinline percentile threshold and filter
+hotter functions. The ``-fdiagnostics-misnoinline-percentile-threshold=N`` accepts
+function entry percentile coldness upto N before emitting a warning. So passing
+``-fdiagnostics-misnoinline-percentile-threshold=50`` will not report diagnostic messages
+if the noinline function's hotness is greater than 50% as per PSI analysis.
+
+MisNoInline diagnostics are also available in the form of optimization remarks,
+which can be serialized and processed through the ``opt-viewer.py``
+scripts in LLVM.
+
+.. option:: -Rpass=misnoinline
+
+  Enables optimization remarks for misnoinline when profiling data conflicts with
+  use of ``noinline`` attribute.
+
+
+.. option:: -Wmisnoinline
+
+  Enables misnoinline warnings when profiling data conflicts with use of
+  ``noinline`` attribute.
+
+.. option:: -fdiagnostics-misnoinline-percentile-threshold=N
+
+  Relaxes misnoinline checking to not emit warning for functions colder than N%.
+
+LLVM supports 4 types of profile formats: Frontend, IR, CS-IR, and
+Sampling. MisNoInline Diagnostics are compatible with all Profiling formats.

+When developers use noinline attribute with a function, i.e., through use of
+``__attribute__((noinline))``, they are trying to communicate that the
+function should not be inlined by the compiler. These can be due to various
+number of reasons to mark a function noinline. If a function is small,
+not critical to the performance of your code and would be called less often,
+especially in cases of error handling, it makes sense to noinline a function.
+These annotations, however, can be incorrect for a variety of reasons:
+changes to the code base may make these functions hot, the developer
+mis-annotated them, or perhaps they assumed something incorrectly when they
+wrote the annotation. Regardless of why, it is useful to detect these
+situations so that the user can rethink and remove the attribute as necessary.
+
+The MisNoInline checks in the LLVM backend follow a simple procedure: if the function entry
+entry count exceeds a certain percentile threshold and the cost of inlining the noinline marked
+function indicates a success, the MisNoInline flags will emit a diagnostic to the user to reconsider
+their stance on the function marking.
+
+The most natural place to perform these checks is in the CGSCC Inliner pass specifically
+where we check the cost of inlining the function. The profile pass has also been run
+up to this point, so information about BFI/PSI is available for further analysis.
+
+
+Instead of stopping our analysis on whether a function needs to be inlined
+in InlinerCost, if we hit a noinline marked function we continue and see if by cost it is
+feasible to inline a function. If so, we do one more check if the function is percentile wise
+hotter than user provided value (If user doesn't provide the value it's 99% by default), and go
+ahead and emit the warning.
+
+The diagnostics are also available in the form of optimization remarks,
+which can be serialized and processed through the ``opt-viewer.py``
+scripts in LLVM.
+
+.. option:: -pass-remarks=misnoinline
+
+  Enables optimization remarks for misnoinline when profiling data conflicts with
+  use of ``noinline`` function attribute.
+
+
+.. option:: pgo-warn-misnoinline
+
+  Enables misnoinline warnings when profiling data conflicts with use of
+  ``noinline`` function attribute.
+
+.. option:: misnoinline-percent
+
+  Relaxes misnoinline checking to not emit warnings for functions colder than Nth percentile.
+
+LLVM supports 4 types of profile formats: Frontend, IR, CS-IR, and
+Sampling. MisNoInline Diagnostics are compatible with all profiling formats.
