- Added some missing strp variants as well
- Fixed comment typo

In preparation for a follow on patch that improves DWARF parsing speed, clean up DWARFFormValue so that we have can get the fixed byte size of a form value given a DWARFUnit or given the version, address byte size and dwarf32/64.
This patch cleans up code so that everyone is using one of the new DWARFFormValue functions:
static Optional<uint8_t> DWARFFormValue::getFixedByteSize(dwarf::Form Form, const DWARFUnit *U = nullptr);
static Optional<uint8_t> DWARFFormValue::getFixedByteSize(dwarf::Form Form, uint16_t Version, uint8_t AddrSize, bool Dwarf32);
This patch changes DWARFFormValue::skipValue() to rely on the output of DWARFFormValue::getFixedByteSize(...) instead of duplicating the code in each function. This will reduce the number of changes we need to make to DWARF to fewer places in DWARFFormValue when we add support for new form.
This patch also starts to support DWARF64 so that we can get correct byte sizes for forms that vary according the DWARF 32/64.
To reduce the code duplication a new FormSizeHelper pure virtual class was created that can be created as a FormSizeHelperDWARFUnit when you have a DWARFUnit, or FormSizeHelperManual where you manually specify the DWARF version, address byte size and DWARF32/DWARF64. There is now a single implementation of a function that gets the fixed byte size (instead of two where one took a DWARFUnit and one took the DWARF version, address byte size and DWARFFormat enum) and one function to skip the form values.

Adds all the intrinsics used for various conversion builtins that will
be added to altivec.h. These are type conversions between various types of
vectors.

This adds support for the compare logical and trap (memory)
instructions that were added as part of the miscellaneous
instruction extensions feature with zEC12.
llvm-svn: 286587
This adds support for the LZRF/LZRG/LLZRGF instructions that were
added on z13, and uses them for code generation were appropriate.
SystemZDAGToDAGISel::tryRISBGZero is updated again to prefer LLZRGF
over RISBG where both would be possible.
llvm-svn: 286586
This adds support for the 31-to-64-bit zero extension instructions
LLGT and LLGTR and uses them for code generation where appropriate.
Since this operation can also be performed via RISBG, we have to
update SystemZDAGToDAGISel::tryRISBGZero so that we prefer LLGT
over RISBG in case both are possible. The patch includes some
simplification to the tryRISBGZero code; this is not intended
to cause any (further) functional change in codegen.

Fails with all versions of arm/aarch64 gcc available on ubuntu 16.04/14.04.
Passes with Linaro GCC version >= 4.8 but fails with >= 5.0. But There are other regressions when we use Linaro GCC.

The change in D26502 splits ReaderWriter.h, which contains the APIs
into both the BitReader and BitWriter libraries, into BitcodeReader.h
and BitcodeWriter.h.
Change lld uses to the appropriate split header, removing it
completely in one case where it wasn't needed.

The change in D26502 splits ReaderWriter.h, which contains the APIs

Change clang uses to the appropriate split header(s).
llvm-svn: 286567
Summary:
Split ReaderWriter.h which contains the APIs into both the BitReader and
BitWriter libraries into BitcodeReader.h and BitcodeWriter.h.
This is to address Chandler's concern about sharing the same API header
between multiple libraries (BitReader and BitWriter). That concern is
why we create a single bitcode library in our downstream build of clang,
which led to r286297 being reverted as it added a dependency that
created a cycle only when there is a single bitcode library (not two as
in upstream).

My script updated lldb::Errors, and I failed to fix it entirely
before pushing. This restore everything in lldb as it was before
r286561.

This is forcing to use Error::success(), which is in a wide majority
of cases a lot more readable.
