startswith/endswith. NFC.
startswith/endswith wrap starts_with/ends_with and will eventually go away (to more closely match string_view)
|
|
Note that llvm::support::endianness has been renamed to
llvm::endianness while becoming an enum class as opposed to an
enum. This patch replaces support::{big,little,native} with
llvm::endianness::{big,little,native}.
|
|
In preparation for removing the `#include "llvm/ADT/StringExtras.h"`
from the header to source file of `llvm/Support/Error.h`, first add in
all the missing includes that were previously included transitively
through this header.

{starts,ends}_with_insensitive (NFC)
This patch migrates uses of StringRef::{starts,ends}with_insensitive
to StringRef::{starts,ends}_with_insensitive so that we can use names
similar to those used in std::string_view. I'm planning to deprecate
StringRef::{starts,ends}with_insensitive once the migration is
complete across the code base.

functions.
This patch replaces the uses of PointerUnion.is function by llvm::isa,
PointerUnion.get function by llvm::cast, and PointerUnion.dyn_cast by
llvm::dyn_cast_if_present. This is according to the FIXME in
the definition of the class PointerUnion.
This patch does not remove them as they are being used in other
subprojects.

and its parents or children with spcified depth.
Right now, if we want to dump symbol at specified offset, we need to use `grep`.
And it can only show surrounding symbols in layout (not in lexical scope sense).
This adds similar options to `dump` command as `llvm-dwarfdump` to allow users
to dump symbol record at specified offset and its parents or children with
spcified depth.
`--symbol-offset=` must be used with `--modi` to dump only one symbol at given
offset.
`--show-parents`/`--show-children` must be used with `--symbol-offset` to
dump all symbols that are parents/children of the symbol at given offset.
`--parent-recurse-depth`/`--children-recurse-depth` must be used with
`--show-parents`/`--show-children` to specify the max up/down depth.

The change described by:
https://reviews.llvm.org/D122226
Moved some llvm-pdbutil functionality to the debug PDB library.
This patch addresses a broken '-modi' argument handling, which
causes an assertion if its value is other than '0' or '1'.
In addition, it moves the assertion for the number of occurrences
of the '-modi' argument from the PDB library into the llvm-pdbutil
driver.

https://reviews.llvm.org/D122226
Moved some llvm-pdbutil functionality to the debug PDB library.
This patch addresses one outstanding issue concerning the global
state (Filters) created in the PDB library.
- Move 'Filters' inside the 'LinePrinter' class.
- Omit 'Optional' and just pass 'PrintScope &HeaderScope' everywhere.

At Sony we are developing llvm-dva
https://lists.llvm.org/pipermail/llvm-dev/2020-August/144174.html
For its PDB support, it requires functionality already present in
llvm-pdbutil.
We intend to move that functionaly into the PDB library to be
shared by both tools. That change will be done in 2 steps, that
will be submitted as 2 patches:
(1) Replace 'ExitOnError' with explicit error handling.
(2) Move the intended shared code to the PDB library.
Patch for step (1): https://reviews.llvm.org/D121801
This patch is for step (2).
Move InputFile.cpp[h], FormatUtil.cpp[h] and LinePrinter.cpp[h]
files to the debug PDB library.
It exposes the following functionality that can be used by tools:
- Open a PDB file.
- Get module debug stream.
- Traverse module sections.
- Traverse module subsections.
Most of the needed functionality is in InputFile, but there are
dependencies from LinePrinter and FormatUtil.
Some other functionality is in the following functions in
DumpOutputStyle.cpp file:
- iterateModuleSubsections
- getModuleDebugStream
- iterateOneModule
- iterateSymbolGroups
- iterateModuleSubsections
Only these specific functions from DumpOutputStyle are moved to
the PDB library.
