Added scalar compare VCMPSS, VCMPSD.
Implemented LowerSELECT for scalar FP operations.
I replaced FSETCCss, FSETCCsd with one node type FSETCCs.
Node extract_vector_elt(v16i1/v8i1, idx) returns an element of type i1.

*h_errno is written not on success, but on failure.
In fact, it seems like it can be written even when return value signals
success, so we just unpoison it in all cases.

FIXME: Host's llvm-config is not generated. It's for target's.
Host tools, aka "BuildTools", in utils, do not require llvm-config to build.
For example with --host=i686-pc-mingw32 --build=linux,
$ BuildTools/Release+Asserts/bin/llvm-config --libs support
-lLLVMSupport
-lpthread -lshell32 -lpsapi -limagehlp -lm
llvm-svn: 197382
LLVM libs are printed in the first line, and system libs are printed in the next line.
$ bin/llvm-config --libs object
-lLLVMObject -lLLVMSupport
-lrt -ldl -ltinfo -lpthread -lz
It is workaround for PR3347 and PR8449.

Summary:
-regex and -iregex both mimic options of the find utility.
Made the default list of extensions case-insensitive, so that it's not only C
and CPP extensions are accepted in upper case.

If NONAME option is given for an export, that symbol will be exported only by
its ordinal. LLD will not emit the symbol name to the export table.

Especially try to keep existing line breaks before raw string literals,
as the code author might have aligned content to it.
Thereby, clang-format now keeps things like:
parseStyle(R"(
BasedOnStyle: Google,
ColumnLimit: 100)");
parseStyle(
R"(BasedOnStyle: Google,
ColumnLimit: 100)");

OrdinalBase is an addend to the ordinals. We used to always set 1 to the field.
Although it produced a valid a DLL export table, it'd be a waste if the first
ordinal does not start with 1 -- we had to have NULL fields at the beginning of
the export address table. By setting the ordinal base, we can eliminate the
NULL fields.
llvm-svn: 197367
You can specify exported function's ordinal by /export:func,@<number> command
line option, but LLD ignored the option until now. This patch implements the
feature.
Ordinal is basically the index into the exported function address table. So,
for example, if /export:foo,@42 is specified, the linker writes foo's address
to 42th entry in the address table. Windows supports import-by-ordinal; you
can not only import a function by name, but by its ordinal. If you want to
allow your DLL users to import your functions by their ordinals, you need to
make sure that your functions are always exported with the same ordinals.
This is the feature for that situation.

An empty string for an ASM input constraint is invalid, and will crash
during clang CodeGen. Change TargetInfo::validateInputConstraint to
reject an empty string.

Currently we have such types as legal vector types. The DAG combiner may generate some DAG nodes having such types but we don't have patterns to match them.
E.g. a load i32 and a bitcast i32 to v1i32 will be combined into a load v1i32:
bitcast (load i32) to v1i32 -> load v1i32.
So this patch fixes such problems for load/dup instructions.
If v1i8/v1i16/v1i32 are not legal any more, the code in this patch can be deleted. So I also add some FIXME.

Some tiny cosmetic code changes to follow. Because of the wide
ranging nature of the patch a full 24 test cycle was needed to
check against regression. This was the smallest patch I could
make to progress from the earlier ones in the series.

These right now just test that the same string is present in two files, but will
become more useful as clang's handling of DataLayout is refactored.

The following are the most significant peculiarities of MIPS target:
- MIPS ABI requires some special tags in the dynamic table.
- GOT consists of two parts local and global. The local part contains
entries refer locally visible symbols. The global part contains entries
refer global symbols.
- Entries in the .dynsym section which have corresponded entries in the
GOT should be:
* Emitted at the end of .dynsym section
* Sorted accordingly to theirs GOT counterparts
- There are "paired" relocations. One or more R_MIPS_HI16 and R_MIPS_GOT16
relocations should be followed by R_MIPS_LO16 relocation. To calculate
result of R_MIPS_HI16 and R_MIPS_GOT16 relocations we need to combine
addends from these relocations and paired R_MIPS_LO16 relocation.
The patch reviewed by Michael Spencer, Shankar Easwaran, Rui Ueyama.

__builtin_va_list and friends have been showing up where they shouldn't for way
to long, making unwanted appearences in -ast-print, tooling and source level
visitors and even the hello world tutorial on the clang website.
This commit factors down the implicit typedef and record creation facilities to
ensure they're marked implicit.
Also fixes a unit test that was testing incorrect behaviour, and removes old
hacks in the DeclPrinter that tried to skip implicit declarations manually.

The warning for backslash and newline separated by whitespace was missed in
this code path.
backslash<whitespace><newline> is handled differently from compiler to compiler
so it's important to warn consistently where there's ambiguity.
Matches similar handling of block comments and non-comment lines.

This is a base implementation of the powerpc-apple-darwin asm parser dialect.
* Enables infrastructure (essentially isDarwin()) and fixes up the parsing of asm directives to separate out ELF and MachO/Darwin additions.
* Enables parsing of {r,f,v}XX as register identifiers.
* Enables parsing of lo16() hi16() and ha16() as modifiers.
The changes to the test case are from David Fang (fangism).

This optional register liveness analysis pass can be enabled with either
-enable-stackmap-liveness, -enable-patchpoint-liveness, or both. The pass
traverses each basic block in a machine function. For each basic block the
instructions are processed in reversed order and if a patchpoint or stackmap
instruction is encountered the current live-out register set is encoded as a
register mask and attached to the instruction.
Later on during stackmap generation the live-out register mask is processed and
also emitted as part of the stackmap.
This information is optional and intended for optimization purposes only. This
will enable a client of the stackmap to reason about the registers it can use
and which registers need to be preserved.

GCC does not support strong enum if -std=c++0x is not used.

_LIBCPP_HAS_NO_STRONG_ENUMS when we are compiling with
g++ without c++0x.
