[SelectionDAG] Fix PR23603.

Summary:
LLVM's MI level notion of invariant_load is different from LLVM's IR
level notion of invariant_load with respect to dereferenceability.  The
IR notion of invariant_load only guarantees that all *non-faulting*
invariant loads result in the same value.  The MI notion of invariant
load guarantees that the load can be legally moved to any location
within its containing function.  The MI notion of invariant_load is
stronger than the IR notion of invariant_load -- an MI invariant_load is
an IR invariant_load + a guarantee that the location being loaded from
is dereferenceable throughout the function's lifetime.

9 years ago[x86-64 ABI] Fix for PR23082: an assertion failure when passing/returning a wrapper...
Andrea Di Biagio [Tue, 2 Jun 2015 19:34:40 +0000 (19:34 +0000)]
[x86-64 ABI] Fix for PR23082: an assertion failure when passing/returning a wrapper union in a full YMM register.

This patch fixes an assertion failure in method
'X86_64ABIInfo::GetByteVectorType'.

Method 'GetByteVectorType' (in TargetInfo.cpp) is responsible
for mapping a QualType 'Ty' (for an argument or return value) to an LLVM IR
type that, according to the ABI, must be passed in a XMM/YMM vector register.

When selecting the IR vector type, method 'GetByteVectorType' always tries to
choose the "best" IR vector type for the 'Ty' in input. In particular, if Ty
is a wrapper structure, it keeps unwrapping it until it finds a vector type VTy.
That VTy is the "preferred IR type".

However, function 'isSingleElementStructure' (used to unwrap structures) does
not know how to look through union types. So, before this patch, if Ty was in
a nest of wrapper structures with at least two union types, we would have
triggered an assertion failure (added at revision 230971).

With this patch, if method 'GetByteVectorType' fails to find the preferred
vector type, we just return a valid (although potentially 'less friendly')
vector type based on the type size. So, rather than asserting on an 'unexpected'
'Ty' in input, we conservatively return vector type <2 x double> if Ty is 16
bytes, or <4 x double> if Ty is 32 bytes.

contains objects with alignment requirements that are larger than the
alignment specified from the given ABI.

We have to use the $fp register as the frame pointer when we perform
dynamic stack realignment. In complex stack frames, with variably-sized
objects, we reserve additionally the callee-saved register $s7 as the
base pointer in order to reference locals.

Fix a race condition where 2 threads might try to call Process::SetExitStatus() at the same time.

The problem was the mutex was only protecting the setting of m_exit_string and m_exit_string, but this function relies on the m_private_state being set to eStateExited in order to prevent more than 1 client setting the exit status. We want to only allow the first caller to succeed.

On MacOSX we have a thread that reaps the process we are debugging, and we also have a thread that monitors the debugserver process. When a process exists, the ProcessGDBRemote::AsyncThread() would set the exit status to the correct value and then another thread would reap the debugserver process and they would often both end up in Process::SetExitStatus() at the same time. With the mutex at the top we allow all variables to be set and the m_private_state to be set to eStateExited _before_ the other thread (debugserver reaped) can try to set th exist status to -1 and "lost connection to debugserver" being set as the exit status.

This was probably an issue for lldb-server as well and could very well cleanup some tests that might have been expecting a specific exit status from the process being debugged.
