6 years ago[AST][1/4] Move the bit-fields from TagDecl, EnumDecl and RecordDecl into DeclContext
Erich Keane [Wed, 1 Aug 2018 20:48:16 +0000 (20:48 +0000)]
[AST][1/4] Move the bit-fields from TagDecl, EnumDecl and RecordDecl into DeclContext

DeclContext has a little less than 8 bytes free due to the alignment
requirements on 64 bits archs. This set of patches moves the
bit-fields from classes deriving from DeclContext into DeclContext.

On 32 bits archs this increases the size of DeclContext by 4 bytes
but this is balanced by an equal or larger reduction in the size
of the classes deriving from it.

On 64 bits archs the size of DeclContext stays the same but
most of the classes deriving from it shrink by 8/16 bytes.
(-print-stats diff here https://reviews.llvm.org/D49728)
When doing an -fsyntax-only on all of Boost this result
in a 3.6% reduction in the size of all Decls and
a 1% reduction in the run time due to the lower cache
miss rate.

For now CXXRecordDecl is not touched but there is
an easy 6 (if I count correctly) bytes gain available there
by moving some bits from DefinitionData into the free
space of DeclContext. This will be the subject of another patch.

This patch sequence also enable the possibility of refactoring
FunctionDecl: To save space some bits from classes deriving from
FunctionDecl were moved to FunctionDecl. This resulted in a
lot of stuff in FunctionDecl which do not belong logically to it.
After this set of patches however it is just a simple matter of
adding a SomethingDeclBitfields in DeclContext and moving the
bits to it from FunctionDecl.

This first patch introduces the anonymous union in DeclContext
and all the *DeclBitfields classes holding the bit-fields, and moves
the bits from TagDecl, EnumDecl and RecordDecl into DeclContext.

Previously, I thought that install-liblldb would fail because CMake had

semantics of `add_custom_target`: the DEPENDS option refers to specific files,
not targets. Therefore `install-liblldb` should rely on the actual liblldb
getting generated rather than the target.

This means that the previous patch I committed (to stop relying on CMake's
framework support) is no longer needed and has been reverted. Using CMake's
framework support greatly simplifies the implementation.

`install-lldb-framework` (and the stripped variant) is as simple as
depending on `install-liblldb` because CMake knows that liblldb was built as a
framework and will install the whole framework for you. The stripped variant
will depend on the stripped variants of individual tools only to ensure they

[dsymutil] Convert recursion in lookForDIEsToKeep into worklist.

The functions `lookForDIEsToKeep` and `keepDIEAndDependencies` can have
some very deep recursion. This tackles part of this problem by removing
the recursion from `lookForDIEsToKeep` by turning it into a worklist.

The difficulty in doing so is the computation of incompleteness, which
depends on the incompleteness of its children. To compute this, we
insert "continuation markers" into the worklist. This informs the work
loop to (re)compute the incompleteness property of the DIE associated
with it (i.e. the parent of the previously processed DIE).

This patch should generate byte-identical output. Unfortunately it also
has some impact of performance, regressing by about 4% when processing

[SystemZ, TableGen] Fix shift count handling

The DAG combiner logic to simplify AND masks in shift counts is invalid.
While it is true that the SystemZ shift instructions ignore all but the
low 6 bits of the shift count, it is still invalid to simplify the AND
masks while the DAG still uses the standard shift operators (which are
*not* defined to match the SystemZ instruction behavior).

Instead, this patch performs equivalent operations during instruction
selection. For completely removing the AND, this now happens via
additional DAG match patterns implemented by a multi-alternative
PatFrags. For simplifying a 32-bit AND to a 16-bit AND, the existing DAG
patterns were already mostly OK, they just needed an output XForm to
actually truncate the immediate value.

Unfortunately, the latter change also exposed a bug in TableGen: it
seems XForms are currently only handled correctly for direct operands of
the outermost operation node. This patch also fixes that bug by simply
recurring through the whole pattern. This should be NFC for all other

[clangd] Make SymbolLocation => bool conversion explicitly.

Summary:
The implicit bool conversion could happen superisingly, e.g. when
checking `if (Loc1 == Loc2)`, the compiler will convert SymbolLocation to
bool before comparing (because we don't define operator `==` for SymbolLocation).

6 years ago[DebugInfo] Have custom std::reverse_iterator<DWARFDie>
Jonas Devlieghere [Wed, 1 Aug 2018 10:24:17 +0000 (10:24 +0000)]
[DebugInfo] Have custom std::reverse_iterator<DWARFDie>

The DWARFDie is a lightweight utility wrapper that stores a pointer to a
compile unit and a debug info entry. Currently, its iterator (used for
walking over its children) stores a DWARFDie and returns a const
reference when dereferencing it.

When the iterator is modified (by incrementing or decrementing it), this
reference becomes invalid. This was happening when calling reverse on
it, because the std::reverse_iterator is keeping a temporary copy of the
iterator (see
https://en.cppreference.com/w/cpp/iterator/reverse_iterator for a good
illustration).

The relevant code in libcxx:

  reference operator*() const {_Iter __tmp = current; return *--__tmp;}

When dereferencing the reverse iterator, we decrement and return a
reference to a DWARFDie stored in the stack frame of this function,
resulting in UB at runtime.

This patch specifies the std::reverse_iterator for DWARFDie to do the
right thing.
