If we're after type legalize, we should make sure we won't create
a store with an illegal type when we separate the AVG pattern
from the truncating store.
I don't know of a way to fail for this today. Just noticed while
I was in the vicinity.
llvm-svn: 368608
Summary:
This bug occurred when a plug-in requested that a binary not be
symbolized while the script is trying to symbolize a stack frame. In
this case `self.frame_no` would not be incremented. This would cause
subsequent stack frames that are symbolized to be incorrectly numbered.
To fix this `get_symbolized_lines()` has been modified to take an
argument that indicates whether the stack frame counter should
incremented. In `process_line_posix()` `get_symbolized_lines(None, ...)`
is now used in in the case where we don't want to symbolize a line so
that we can keep the frame counter increment in a single function.
A test case is included. The test uses a dummy plugin that always asks
`asan_symbolize.py` script to not symbolize the first binary that the
script asks about. Prior to the patch this would cause the output to
script to look something like
```
#0 0x0
#0 0x0 in do_access
#1 0x0 in main
```
This is the second attempt at landing this patch. The first (r368373)
failed due to failing some android bots and so was reverted in r368472.
The new test is now disabled for Android. It turns out that the patch
also fails for iOS too so it is also disabled for that family of
platforms too.

Path is now stored in the references to the child while serializing,
then this path is used to generate the relative path in the HTML
generator.
Now some references have paths and some don't so in the reducing phase,
references are now properly merged checking for empty attributes.
Tests added for HTML and YAML generators, merging and serializing.
computeRelativePath function had a bug when the filepath is part of the
given directory; it returned a path that starts with a separator. This
has been fixed.

Summary:
We were using implicit deduction guides instead of explicit ones,
however the implicit ones don't do work anymore when changing the
constructors.
This commit adds the actual guides specified in the Standard to make
libc++ (1) closer to the Standard and (2) more resistent to changes
in std::tuple's constructors.

llvm-svn: 368599
Summary:
This commit fixed a race condition from multi-threaded thinLTO backends that causes non-deterministic memory corruption for a data structure used only by AutoFDO with compact binary profile.
GUIDToFuncNameMap, a static data member of type DenseMap in FunctionSamples is used as a per-module mapping from function name MD5 to name string when input AutoFDO profile is in compact binary format. However with ThinLTO, we can have parallel backends modifying and accessing the class static map concurrently. The fix is to make GUIDToFuncNameMap a member of SampleProfileLoader instead of a file static data.

Summary:
This takes this logic out of the Tweak class, and simplifies the signature of
the function where the main logic is.
The goal is to make it easier to turn into a loop like:
for (current = N; current and current->parent are both expr; current = current->parent)
if (suitable(current))
return current;
return null;

Summary:
Few corrections with no functional change:
- replacing `%zd` with `%zu` all around: the values are unsigned
- prefer `MAP_ANONYMOUS` to `MAP_ANON` (it's deprecated)
- remove the unused `enum LinkerInitialized`
- mark a parameter as `UNUSED` in Fuchsia's `getRandom`
- correct the casing of a variable and use `nullptr` instead of 0 for
pointers in `list.h`
- reorder some `typedef` to be consistent between `signed` and
`unsigned`

> Patch https://reviews.llvm.org/D43256 introduced more aggressive loop layout optimization which depends on profile information. If profile information is not available, the statically estimated profile information(generated by BranchProbabilityInfo.cpp) is used. If user program doesn't behave as BranchProbabilityInfo.cpp expected, the layout may be worse.
>
> To be conservative this patch restores the original layout algorithm in plain mode. But user can still try the aggressive layout optimization with -force-precise-rotation-cost=true.

The returned value is currently unused. It also seems to imply that
it somehow represents 'printf-style' the number of characters/bytes
written to some output stream (which is incorrect, as we only know
the actual size of the written message when we have rendered it,
e.g. via GetString and DiagnosticManagers have no associated
output stream).

The internal representation of llvm-ar archives uses linux style slashes
for paths, no matter the OS. In the case of windows this meant file
paths input intending to match existing members would only match if
linux style slashes where used. This change allows either slash
direction to be input by the user.
This change includes removing an unnecessary call to normalisePath and
moving the call of another.

Summary:
Ana Pazos reported a bug where we were not checking that an APInt would
fit into 64-bits before calling `getSExtValue()`. This caused asserts when
compiling large constants, such as i128s, as happens when compiling compiler-rt.
This patch adds a testcase and makes the callback less error-prone.
