green the bots for now. I don't think this is a huge issue since the

up such a pipeline (ie N cc1's for N c files followed by another N cc1's

4 years ago[ORC] Add support for emulated TLS to ORCv2.

[ORC] Add support for emulated TLS to ORCv2.

This commit adds a ManglingOptions struct to IRMaterializationUnit, and replaces
IRCompileLayer::CompileFunction with a new IRCompileLayer::IRCompiler class. The
ManglingOptions struct defines the emulated-TLS state (via a bool member,
EmulatedTLS, which is true if emulated-TLS is enabled and false otherwise). The
IRCompileLayer::IRCompiler class wraps an IRCompiler (the same way that the
CompileFunction typedef used to), but adds a method to return the
IRCompileLayer::ManglingOptions that the compiler will use.

These changes allow us to correctly determine the symbols that will be produced
when a thread local global variable defined at the IR level is compiled with or
without emulated TLS. This is required for ORCv2, where MaterializationUnits
must declare their interface up-front.

Most ORCv2 clients should not require any changes. Clients writing custom IR
compilers will need to wrap their compiler in an IRCompileLayer::IRCompiler,
rather than an IRCompileLayer::CompileFunction, however this should be a
straightforward change (see modifications to CompileUtils.* in this patch for an
example).

- Expand AutoType to include optional type-constraint, reflecting the wording and easing the integration of constraints.
- Replace autos in parameter type specifiers with invented parameters in GetTypeSpecTypeForDeclarator, using the same logic

  - Tracking the template parameter depth before parsing function declarators (at which point we can match template
    parameters against scope specifiers to know if we have an explicit template parameter list to append invented parameters
    to or not).
- When encountering an AutoType in a parameter context we check a stack of InventedTemplateParameterInfo structures that
  contain the info required to create and accumulate invented template parameters (fields that were already present in

Fix an over-suspend bug with LaunchInNewTerminalWithAppleScript sessions

and the darwin-debug helper program, we could often end up with the
inferior process having a too-high suspend count, and it would never
resume execution.

lldb tries to wait until darwin-debug has finished its work and has
launched the inferior (WaitForProcessToSIGSTOP) but this wasn't
working correctly - and cannot be made to work.

This patch removes WaitForProcessToSIGSTOP, adds a special tiny
segment to the darwin-debug executable so it can be identified as
that binary (ExecExtraSuspend), and adds code to debugserver to
detect this segment.  When debugserver sees this segment, it notes
that the next exec will be done with a launch-suspended flag.  When
the next exec happens, debugserver forces an extra task_resume when
we resume the inferior.

An alternative approach would be if lldb could detect when the
inferior has been launched by darwin-debug unambiguously; monitoring
when the unix socket between darwin-debug and lldb was closed would
have been a reasonable way to do this too.

[lldb/DataFormatters] Fix the `$$deference$$` synthetic child

Summary:
The ValueObject code checks for a special `$$dereference$$` synthetic
child to allow formatter providers to implement a natural
dereferencing behavior in `frame variable` for objects like smart
pointers.

This support was broken when used directly throught the Python API and
not trhough `frame variable`. The reason is that
SBFrame.FindVariable() will return by default the synthetic variable
if it exists, while `frame variable` will not do this eagerly. The
code in `ValueObject::Dereference()` accounted for the latter but not
for the former. The fix is trivial. The test change includes
additional covergage for the already-working bahevior as it wasn't
covered by the testsuite before.

This commit also adds a short piece of documentatione explaining that
it is possible (even advisable) to provide this synthetic child
outstide of the range of the normal children.

Thomas Lively [Fri, 13 Dec 2019 18:41:25 +0000 (10:41 -0800)]
[WebAssembly][InstrEmitter] Foundation for multivalue call lowering

Summary:
WebAssembly is unique among upstream targets in that it does not at
any point use physical registers to store values. Instead, it uses
virtual registers to model positions in its value stack. This means
that some target-independent lowering activities that would use
physical registers need to use virtual registers instead for
WebAssembly and similar downstream targets. This CL generalizes the
existing `usesPhysRegsForPEI` lowering hook to
`usesPhysRegsForValues` in preparation for using it in more places.

One such place is in InstrEmitter for instructions that have variadic
defs. On register machines, it only makes sense for these defs to be
physical registers, but for WebAssembly they must be virtual registers
like any other values. This CL changes InstrEmitter to check the new
target lowering hook to determine whether variadic defs should be
physical or virtual registers.

These changes are necessary to support a generalized CALL instruction
for WebAssembly that is capable of returning an arbitrary number of
arguments. Fully implementing that instruction will require additional
changes that are described in comments here but left for a follow up
commit.

[ARM] Follow AACPS standard for volatile bit-fields access width

Summary:
This patch resumes the work of D16586.
According to the AAPCS, volatile bit-fields should
be accessed using containers of the widht of their
declarative type. In such case:
```
struct S1 {
  short a : 1;
}
```
should be accessed using load and stores of the width
(sizeof(short)), where now the compiler does only load
the minimum required width (char in this case).
However, as discussed in D16586,
that could overwrite non-volatile bit-fields, which
conflicted with C and C++ object models by creating
data race conditions that are not part of the bit-field,
e.g.
```
struct S2 {
  short a;
  int  b : 16;
}
```
Accessing `S2.b` would also access `S2.a`.

The AAPCS Release 2019Q1.1
(https://static.docs.arm.com/ihi0042/g/aapcs32.pdf)
section 8.1 Data Types, page 35, "Volatile bit-fields -
preserving number and width of container accesses" has been
updated to avoid conflict with the C++ Memory Model.
Now it reads in the note:
```
This ABI does not place any restrictions on the access widths
of bit-fields where the container overlaps with a non-bit-field member.
 This is because the C/C++ memory model defines these as being separate
memory locations, which can be accessed by two threads
 simultaneously. For this reason, compilers must be permitted to use a
narrower memory access width (including splitting the access
 into multiple instructions) to avoid writing to a different memory location.
```

I've updated the patch D16586 to follow such behavior by verifying that we
only change volatile bit-field access when:
 - it won't overlap with any other non-bit-field member
 - we only access memory inside the bounds of the record

Regarding the number of memory accesses, that should be preserved, that will
be implemented by D67399.
