Erik Pilkington e7e8772446 [ItaniumMangle] Undeduced auto type shouldn't be substitutable.
We still support the old mangling if we're trying to be ABI-compatible with
Clang 6.0, though.

Ben Hamilton 345f8739d8 [clang-format/ObjC] Use getIdentifierInfo() instead of tok::identifier
Summary:
Previously, we checked tokens for `tok::identifier` to see if they
were identifiers inside an Objective-C selector.

However, this missed C++ keywords like `new` and `delete`.

To fix this, this diff uses `getIdentifierInfo()` to find
identifiers or keywords inside Objective-C selectors.

Test Plan: New tests added. Ran tests with:
  % make -j16 FormatTests && ./tools/clang/unittests/Format/FormatTests

As discussed in the post-commit thread for:
rL330437 ( http://lists.llvm.org/pipermail/llvm-commits/Week-of-Mon-20180423/545906.html )

We need a way to opt-out of a float-to-int-to-float cast optimization because too much

Sven van Haastregt 4700faa28e [OpenCL] Add separate read_only and write_only pipe IR types
SPIR-V encodes the read_only and write_only access qualifiers of pipes,
so separate LLVM IR types are required to target SPIR-V.  Other backends
may also find this useful.

These new types are `opencl.pipe_ro_t` and `opencl.pipe_wo_t`, which
replace `opencl.pipe_t`.

This replaces __get_pipe_num_packets(...) and __get_pipe_max_packets(...)
which took a read_only pipe with separate versions for read_only and
write_only pipes, namely:

 * __get_pipe_num_packets_ro(...)
 * __get_pipe_num_packets_wo(...)
 * __get_pipe_max_packets_ro(...)
 * __get_pipe_max_packets_wo(...)

These separate versions exist to avoid needing a bitcast to one of the
two qualified pipe types.

Summary:
This patch moves the MultiplexASTDeserializationListener declaration into a public header.

We're currently using this multiplexer in the cling interpreter to attach another
ASTDeserializationListener during the execution (so, after the MultiplexConsumer is already
attached which prevents us from attaching more). So far we're doing this by patching clang
and making this class public, but it makes things easier if we make this instead just public in
upstream.

Akira Hatanaka ccda3d2970 [CodeGen] Avoid destructing a callee-destructued struct type in a
function if a function delegates to another function.

Fix a bug introduced in r328731, which caused a struct with ObjC __weak
fields that was passed to a function to be destructed twice, once in the
callee function and once in another function the callee function
delegates to. To prevent this, keep track of the callee-destructed
structs passed to a function and disable their cleanups at the point of
the call to the delegated function.

This reapplies r331016, which was reverted in r331019 because it caused
an assertion to fail in EmitDelegateCallArg on a windows bot. I made
changes to EmitDelegateCallArg so that it doesn't try to deactivate
cleanups for structs that have trivial destructors (cleanups for those
structs are never pushed to the cleanup stack in EmitParmDecl).

Ana Pazos c85505450a [RISCV] More validations on the input value of -march=
Supporting additional rules for parsing ISA string.

- RISC-V ISA strings must be lowercase.
E.g.: rv32IMC is not supported, rv32imc is correct.

- Multi-letter extensions are to be separated by a single
underscore '_'. The extension prefix counts as a letter.
This means extensions that start with 's', 'sx' and 'sx'
are all multi-letter.
E.g.:
xasb is a single non-standard extension named 'xasb'
xa_sb are two extensions, the non-standard user level extension
'xa', and the supervisor level extension 'sb'.

- Standard user-level extensions are specified following
a canonical order, according to Table 22.1 in
RISC-V User-Level ISA V2.2.

- Non-standard user-level 'x' extensions,
standard supervisor-level 's' extensions and
non-standard supervisor-level 'sx' extensions
are also specified following a canonical order according
to Table 22.1 in RISC-V User-Level ISA V2.2:
'x' extensions, follwed by 's' extensions and then 'sx' extensions.

- Extensions might have a version number.
Underscores may be used to separate ISA subset components to
improve readability and to provide disambiguation.
E.g.: rv32i2_m3_a1_f2_d2

- Version numbers are divided into major and minor numbers,
separated by a 'p'. If the minor version is 0, then 'p0' can
be omitted.

- Additional checks for dependent extensions and invalid
extensions combinations.
E.g.:
'e' requires rv32
'e' can't be combined with 'f' nor 'd'
'q' requires rv64

- TODO items have also been marked with comments in the code.

Artem Dergachev 516837f2a1 [analyzer] Enable analysis of WebKit "unified sources".
Normally the analyzer begins path-sensitive analysis from functions within
the main file, even though the path is allowed to go through any functions
within the translation unit.

When a recent version of WebKit is compiled, the "unified sources" technique
is used, that assumes #including multiple code files into a single main file.
Such file would have no functions defined in it, so the analyzer wouldn't be
able to find any entry points for path-sensitive analysis.

This patch pattern-matches unified file names that are similar to those
used by WebKit and allows the analyzer to find entry points in the included
code files. A more aggressive/generic approach is being planned as well.

Martin Storsjo 1fab23da1c [Driver] Fix implicit config files from prefixed symlinks
If -no-canonical-prefixes isn't used, the clang executable name used
is the one of the actual executable, not the name of the symlink that
the user invoked.

In these cases, the target prefix was overridden based on the clang
executable name. (On the other hand the implicit -target option
that such a symlink adds, is added as an actual command line parameter
in tools/driver/driver.cop, before resolving the symlink and finding
the actual clang executable.

Use the original ClangNameParts (set from argv[0] in
tools/driver/driver.cpp) if it seems to be initialized propery.

All existing tests of this feature used -no-canonical-prefixes
(possibly because it also makes the driver look in the directory
of the symlink instead of the directory of the executable); add
another one that uses --config-user-dir= to specify the directory
instead. (For actual users of such symlinks, outisde of the test
suite, the directory is probably the same for both.)

This makes this feature work more like what the documentation
describes.
