Introduce unify-loop-exits pass.

For each natural loop with multiple exit blocks, this pass creates a
new block N such that all exiting blocks now branch to N, and then
control flow is redistributed to all the original exit blocks.

The bulk of the tranformation is a new function introduced in
BasicBlockUtils that an redirect control flow from a set of incoming
blocks to a set of outgoing blocks via a common "hub".

This is a useful workaround for a limitation in the structurizer which
incorrectly orders blocks when processing a nest of loops. This pass
bypasses that issue by ensuring that each natural loop is recognized
as a separate region. Since the structurizer is a region pass, it no
longer sees a nest of loops in a single region, and instead processes
each "level" in the nesting as a separate region.

The AMDGPU backend provides a new option to enable this pass before
the structurizer, which may eventually be enabled by default.

[ELF] Allow SHF_LINK_ORDER and non-SHF_LINK_ORDER to be mixed

Currently, `error: incompatible section flags for .rodata` is reported
when we mix SHF_LINK_ORDER and non-SHF_LINK_ORDER sections in an output section.

This is overconstrained. This patch allows mixed flags with the
requirement that SHF_LINK_ORDER sections must be contiguous. Mixing
flags is used by Linux aarch64 (https://github.com/ClangBuiltLinux/linux/issues/953)

  .init.data : { ... KEEP(*(__patchable_function_entries)) ... }

When the integrated assembler is enabled, clang's -fpatchable-function-entry=N[,M]
implementation sets the SHF_LINK_ORDER flag (D72215) to fix a number of
garbage collection issues.

Strictly speaking, the ELF specification does not require contiguous
SHF_LINK_ORDER sections but for many current uses of SHF_LINK_ORDER like
.ARM.exidx/__patchable_function_entries there has been a requirement for
the sections to be contiguous on top of the requirements of the ELF
specification.

This patch also imposes one restriction: SHF_LINK_ORDER sections cannot
be separated by a symbol assignment or a BYTE command. Not allowing BYTE
is a natural extension that a non-SHF_LINK_ORDER cannot be a separator.
Symbol assignments can delimiter the contents of SHF_LINK_ORDER
sections.  Allowing SHF_LINK_ORDER sections across symbol assignments
(especially __start_/__stop_) can make things hard to explain. The
restriction should not be a problem for practical use cases.

Pavel Labath [Thu, 26 Mar 2020 12:23:51 +0000 (13:23 +0100)]
[lldb] Fix another crash in covariant type handling

Summary:
D73024 seems to have fixed one set crash, but it introduced another.
Namely, if a class contains a covariant method returning itself, the
logic in MaybeCompleteReturnType could cause us to attempt a recursive
import, which would result in an assertion failure in
clang::DeclContext::removeDecl.

For some reason, this only manifested itself if the class contained at
least two member variables, and the class itself was imported as a
result of a recursive covariant import.

This patch fixes the crash by not attempting to import classes which are
already completed in MaybeCompleteReturnType. However, it's not clear to
me if this is the right fix, or if this should be handled automatically
by functions lower in the stack.

[LangRef] Clarify the semantics of branch on undef

Summary:
This patch clarifies the semantics of branching on undef value.

Defining `br undef` as undefined behavior explains optimizations that use branch conditions, such as CVP (D76931) and GVN (propagateEquality).

For `switch cond`, it is defined to raise UB if cond is an expression containing undef && cond is not frozen &&
it may yield different values.
This allows that at the destination block the branch condition can be assumed to be frozen already (otherwise UB was already triggered).
This condition is slightly stricter than MemorySanitizer, which allows undef-y condition if it always leads to the same destination,
but it does not break MemorySanitizer because we are giving stricter constraint.

for several analyses/transforms. This patch introduces aligned_alloc
in target library info and memory builtins. Subsequent ones will
make other passes aware and fix https://bugs.llvm.org/show_bug.cgi?id=44062

This change will also be useful to LLVM generators that need to allocate
buffers of vector elements larger than 16 bytes (for eg. 256-bit ones),
element boundary alignment for which is not typically provided by glibc malloc.
