5 years agoChange lldb-test to use ParseAllDebugSymbols.
Zachary Turner [Wed, 9 Jan 2019 21:20:44 +0000 (21:20 +0000)]
Change lldb-test to use ParseAllDebugSymbols.

ParseDeclsForContext was originally created to serve the very specific
case where the context is a function block. It was never intended to be
used for arbitrary DeclContexts, however due to the generic name, the
DWARF and PDB plugins implemented it in this way "just in case". Then,
lldb-test came along and decided to use it in that way.

Related to this, there are a set of functions in the SymbolFile class
interface whose requirements and expectations are not documented. For
example, if you call ParseCompileUnitFunctions, there's an inherent
requirement that you create entries in the underlying clang AST for
these functions as well as their signature types, because in order to
create an lldb_private::Function object, you have to pass it a
CompilerType for the parameter representing the signature.

On the other hand, there is no similar requirement (either inherent or
documented) if one were to call ParseDeclsForContext. Specifically, if
one calls ParseDeclsForContext, and some variable declarations, types,
and other things are added to the clang AST, is it necessary to create
lldb::Variable, lldb::Type, etc objects representing them? Nobody knows.
There is, however, an accidental requirement, because since all of the
plugins implemented this just in case, lldb-test came along and used
ParsedDeclsForContext, and then wrote check lines that depended on this.

When I went to try and implemented the NativePDB reader, I did not
adhere to this (in fact, from a layering perspective I went out of my
way to avoid it), and as a result the existing DIA PDB tests don't work
when the native PDB reader is enabled, because they expect that calling
ParseDeclsForContext will modify the *module's* view of symbols, and not
just the internal AST.

All of this confusion, however, can be avoided if we simply stick to
using ParseDeclsForContext for its original intended use case (blocks),
and use a different function (ParseAllDebugSymbols) for its intended use
case which is, unsuprisingly, to parse all the debug symbols (which is
all lldb-test really wanted to do anyway).

In the future, I would like to change ParseDeclsForContext to
ParseDeclsForFunctionBlock, then delete all of the dead code inside that
handles other types of DeclContexts (and probably even assert if the
DeclContext is anything other than a block).

A few PDB tests needed to be fixed up as a result of this, and this also
exposed a couple of bugs in the DIA PDB reader (doesn't matter much
since it should be going away soon, but worth mentioning) where the
appropriate AST entries weren't being created always.

ELF: create "container" sections from PT_LOAD segments

Summary:
This is the result of the discussion in D55356, where it was suggested
as a solution to representing the addresses that logically belong to a
module in memory, but are not a part of any of its sections.

The ELF PT_LOAD segments are similar to the MachO "load commands",
except that the relationship between them and the object file sections
is a bit weaker. While in the MachO case, the sections belonging to a
specific segment are placed directly inside it in the object file
logical structur, in the ELF case, the sections and segments form two
separate hierarchies. This means that it is in theory possible to create
an elf file where only a part of a section would belong to some segment
(and another part to a different one). However, I am not aware of any
tool which would produce such a file (and most tools will have problems
ingesting them), so this means it is still possible to follow the MachO
model and make sections children of the PT_LOAD segments.

In case we run into (corrupt?) files with overlapping sections, I have
added code (and tests) which adjusts the sizes and/or drops the offending
sections in order to present a reasonable image to the upper layers of
LLDB. This is mostly done for completeness, as I don't anticipate
running into this situation in the real world. However, if we do run
into it, and the current behavior is not suitable for some reason, we
can implement this logic differently.

[AST] Move back BasePathSize to the bit-fields of CastExpr

The number of trailing CXXBaseSpecifiers in CastExpr was moved from
CastExprBitfields to a trailing object in r338489 (D50050). At this time these
bit-fields classes were only 32 bits wide. However later r345459 widened these
bit-field classes to 64 bits.

The reason for this change was that on 64 bit archs alignment requirements
caused 4 bytes of padding after the Stmt sub-object in nearly all expression
classes. Reusing this padding yielded an >10% reduction in the size used by all
statement/expressions when parsing all of Boost (on a 64 bit arch). This
increased the size of statement/expressions for 32 bits archs, but this can be
mitigated by moving more data to the bit-fields of Stmt (and moreover most
people now care about 64 bits archs as a host).

Therefore move back the number of CXXBaseSpecifiers in CastExpr to the
bit-fields of Stmt. This in effect mostly revert r338489 while keeping the
added test.

[DebugInfo] Omit location list entries with empty ranges

Summary:
This fixes PR39710. In that case we emitted a location list looking like
this:

.Ldebug_loc0:
        .quad   .Lfunc_begin0-.Lfunc_begin0
        .quad   .Lfunc_begin0-.Lfunc_begin0
        .short  1                       # Loc expr size

        .short  1                       # Loc expr size
        .byte   85                      # super-register DW_OP_reg5
        .quad   0
        .quad   0

As seen, the first entry's beginning and ending addresses evalute to 0,
which meant that the entry inadvertently became an "end of list" entry,
resulting in the location list ending sooner than expected.

To fix this, omit all entries with empty ranges. Location list entries
with empty ranges do not have any effect, as specified by DWARF, so we
might as well drop them:

"A location list entry (but not a base address selection or end of list
 entry) whose beginning and ending addresses are equal has no effect
 because the size of the range covered by such an entry is zero."

[IPT] Drop cache less eagerly in GVN and LoopSafetyInfo

Current strategy of dropping `InstructionPrecedenceTracking` cache is to
invalidate the entire basic block whenever we change its contents. In fact,
`InstructionPrecedenceTracking` has 2 internal strictures: `OrderedInstructions`
that is needed to be invalidated whenever the contents changes, and the map
with first special instructions in block. This second map does not need an
update if we add/remove a non-special instuction because it cannot
affect the contents of this map.

This patch changes API of `InstructionPrecedenceTracking` so that it now
accounts for reasons under which we invalidate blocks. This should lead
to much less recalculations of the map and should save us some compile time
because in practice we don't typically add/remove special instructions.

hwasan: Ignore loads and stores of size 0.

Now that memory intrinsics are instrumented, it's more likely that
CheckAddressSized will be called with size 0. (It was possible before
with IR like:

  %val = load [0 x i8], [0 x i8]* %ptr

but I don't think clang will generate IR like that and the optimizer
would normally remove it by the time it got anywhere near our pass
anyway). The right thing to do in both cases is to disable the
addressing checks (since the underlying memory intrinsic is a no-op),
so that's what we do.

[ARM][AArch64] Increase TLS alignment to reserve space for Android's TCB

ARM and AArch64 use TLS variant 1, where the first two words after the
thread pointer are reserved for the TCB, followed by the executable's TLS
segment. Both the thread pointer and the TLS segment are aligned to at
least the TLS segment's alignment.

Android/Bionic historically has not supported ELF TLS, and it has
allocated memory after the thread pointer for several Bionic TLS slots
(currently 9 but soon only 8). At least one of these allocations
(TLS_SLOT_STACK_GUARD == 5) is widespread throughout Android/AArch64
binaries and can't be changed.

To reconcile this disagreement about TLS memory layout, set the minimum
alignment for executable TLS segments to 8 words on ARM/AArch64, which
reserves at least 8 words of memory after the TP (2 for the ABI-specified
TCB and 6 for alignment padding). For simplicity, and because lld doesn't
know when it's targeting Android, increase the alignment regardless of
operating system.
