8dab504799 [Support/Unix] Unconditionally include time.h.
When building LLVM on Linux with libc++ with CMake TIME_WITH_SYS_TIME is
undefined, and HAVE_SYS_TIME_H is defined. This ends up including
sys/time.h but not time.h. Unix/TimeValue.inc requires time.h for asctime_r
and localtime. libstdc++ seems to include time.h anyway, but libc++ does
not.

Fix this by always including time.h

9dc06bd431 Conflict with st_dev/st_ino identifiers under Debian GNU/Hurd
The problem is that the struct file_status on UNIX systems has two
members called st_dev and st_ino; those are also members of the
struct stat, and they are reserved identifiers which can also be
provided as #define (and this is the case for st_dev on Hurd).
The solution (attached) is to rename them, for example adding a
"fs_" prefix (= file status) to them.

4bb87cbac5 SmallPtrSet: Reuse DenseMapInfo's pointer hash function instead of inventing a bad one ourselves.
DenseMap's hash function uses slightly more entropy and reduces hash collisions
significantly.  I also experimented with Hashing.h, but it didn't gave a lot of
improvement while being much more expensive to compute.

541b2a4aa3 In MemoryBuffer::getOpenFile() make sure that the buffer is null-terminated if
the caller requested a null-terminated one.

When mapping the file there could be a racing issue that resulted in the file being larger
than the FileSize passed by the caller. We already have an assertion
for this in MemoryBuffer::init() but have a runtime guarantee that
the buffer will be null-terminated, so do a copy that adds a null-terminator.

Protects against crash of rdar://11161822.

ed7692a136 Replace the hashing functions on APInt and APFloat with overloads of the
new hash_value infrastructure, and replace their implementations using
hash_combine. This removes a complete copy of Jenkin's lookup3 hash
function (which is both significantly slower and lower quality than the
one implemented in hash_combine) along with a somewhat scary xor-only
hash function.

Now that APInt and APFloat can be passed directly to hash_combine,
simplify the rest of the LLVMContextImpl hashing to use the new
infrastructure.

0b66c6fca2 Rewrite LLVM's generalized support library for hashing to follow the API
of the proposed standard hashing interfaces (N3333), and to use
a modified and tuned version of the CityHash algorithm.

Some of the highlights of this change:
 -- Significantly higher quality hashing algorithm with very well
    distributed results, and extremely few collisions. Should be close to
    a checksum for up to 64-bit keys. Very little clustering or clumping of
    hash codes, to better distribute load on probed hash tables.
 -- Built-in support for reserved values.
 -- Simplified API that composes cleanly with other C++ idioms and APIs.
 -- Better scaling performance as keys grow. This is the fastest
    algorithm I've found and measured for moderately sized keys (such as
    show up in some of the uniquing and folding use cases)
 -- Support for enabling per-execution seeds to prevent table ordering
    or other artifacts of hashing algorithms to impact the output of
    LLVM. The seeding would make each run different and highlight these
    problems during bootstrap.

This implementation was tested extensively using the SMHasher test
suite, and pased with flying colors, doing better than the original
CityHash algorithm even.

I've included a unittest, although it is somewhat minimal at the moment.
I've also added (or refactored into the proper location) type traits
necessary to implement this, and converted users of GeneralHash over.

My only immediate concerns with this implementation is the performance
of hashing small keys. I've already started working to improve this, and
will continue to do so. Currently, the only algorithms faster produce
lower quality results, but it is likely there is a better compromise
than the current one.

Many thanks to Jeffrey Yasskin who did most of the work on the N3333
paper, pair-programmed some of this code, and reviewed much of it. Many
thanks also go to Geoff Pike Pike and Jyrki Alakuijala, the original
authors of CityHash on which this is heavily based, and Austin Appleby
who created MurmurHash and the SMHasher test suite.

Also thanks to Nadav, Tobias, Howard, Jay, Nick, Ahmed, and Duncan for
all of the review comments! If there are further comments or concerns,
please let me know and I'll jump on 'em.

fdf0dc9e0b Support was removed from LLVM's MIPS backend for the PSP variant of that
chip in r139383, and the PSP components of the triple are really
annoying to parse. Let's leave this chapter behind. There is no reason
to expect LLVM to see a PSP-related triple these days, and so no
reasonable motivation to support them.

It might be reasonable to prune a few of the older MIPS triple forms in
general, but as those at least cause no burden on parsing (they aren't
both a chip and an OS!), I'm happy to leave them in for now.

They're private static methods but we can just make them static

conventions.

58604cd944 Change default error_code ctor to a 'named ctor' so it's more self-documenting.
Unify default construction of error_code uses on this idiom so that users don't
feel compelled to make static globals for naming convenience. (unfortunately I
couldn't make the original ctor private as some APIs don't return their result,
instead using an out parameter (that makes sense to default construct) - which
is a bit of a pity. I did, however, find/fix some cases of unnecessary default
construction of error_code before I hit the unfixable cases)

If someone would prefer a clear name for the 'success' error_value we could
come up with one - potentially just a 'named constructor' style
'error_value::success()' to make this expression more self-documenting. If
I see this come up in other cases I'll certainly consider it.

8a86887ba3 use getHostTriple instead of getDefaultTargetTriple in getClosestTargetForJIT
Get back getHostTriple.

For JIT compilation, use the host triple instead of the default
target: this fixes some JIT testcases that used to fail when the
compiler has been configured as a cross compiler.

These annotations are disabled entirely when either ENABLE_THREADS is off, or

initialization is actually benign. Thanks to Kostya Serebryany for helping
write this patch!

d8b7aa2613 Enhance llvm::SourceMgr to support diagnostic ranges, the same way clang does. Enhance
the X86 asmparser to produce ranges in the one case that was annoying me, for example:

test.s:10:15: error: invalid operand for instruction
movl 0(%rax), 0(%edx)
              ^~~~~~~

It should be straight-forward to enhance filecheck, tblgen, and/or the .ll parser to use 
ranges where appropriate if someone is interested.

6e6a558ebc Add a bad char heuristic to StringRef::find.
Based on Horspool's simplified version of Boyer-Moore. We use a constant-sized table of
uint8_ts to keep cache thrashing low, needles bigger than 255 bytes are uncommon anyways.

The worst case is still O(n*m) but we do a lot better on the average case now.

It extremely breaks builds when optimization is enabled. Twine should not hold temporary objects.

By the way, I might feel sad if I saw "i786-" "i1586-" or "iF86-".

aabc6a9b79 Remove the hack to check UNAME_RELEASE when identifying the Darwin version.
This was only needed to locate llvm-gcc's installation directory when clang
falls back to run llvm-gcc for i386 kexts.  As of clang svn r140187, we're
now just searching paths with several different Darwin versions on either
side of the current version, so this is no longer needed.

(sizeof(off_t) == 32 on i686) which corrupts the stack.

c4cc40c001 One more patch towards JIT support for Mips.
- Add TSFlags for the instruction formats. The idea here is to use
  as much encoding as possible from getBinaryCodeForInstr, and having
  TSFLags formats for that would make it easier to encode most part
  of the instructions (since Mips encodings are pretty straightforward)
- Improve the mips mechanism for compilation callback
- Add Mips specific code for invalidating the instruction cache
- Next patch will address wrong tablegen encoding

fb23462889 Add NativeClient operating system support.
This patch adds support of NativeClient (*-*-nacl) OS support to LLVM.
It's already supported in autoconf/config.sub.

The motivation for this change is to start upstreaming PNaCl work. The
whole set of patches include llvm backends (i686, x86_64, ARM),
llvm-gcc (probably, would not be upstreamed because it's deprecated)
and clang (the work has been just started, the amount of changes is
going to be low and the most of the work is expected to be done close
to the mainline).

3c036e520e Teach Path::GetCurrentDirectory to use $PWD, to support users who like to do
screwy things by setting PWD != getcwd(). For example, some developers I know
will use this to control the value in gcc's DW_AT_comp_dir value in debug
output. With this patch, that trick will now work on clang too.

The only other effect of this change is that the static analysis will now
respect $PWD when reporting the directory of the files in its HTML output. I
think that's fine.

48ac8e9be7 Move TargetRegistry.cpp from lib/Support to lib/Target where it belongs.
The header file was already properly located. The previous need for it
in Support had to do with the version string printing which was fixed in
r135757.

Also update build dependencies where libraries that needed the
functionality of the Target library (in the form of the TargetRegistry)
were picking it up via Support. This is pretty pervasive, essentially
every TargetInfo library (ARMInfo, etc) uses TargetRegistry, making it
depend on Target. All of these were previously just sneaking by.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135760 91177308-0d34-0410-b5e6-96231b3b80d8

4039313b4c Move the registered target printing in version strings completely out of
the Support library. Now its part of the TargetRegistry, and the three
commands that care about this explicitly register this extra bit of
version information.

The set of commands which care was computed by intersecting those which
use the Support library's version string printing and those that
initialize all the registered targets in a way that produces
a meaningful list. The only odd ball out is that 'clang -cc1as -version'
no longer prints the registered targets. I don't think anyone is really
interested in that (especially as the fact that llvm-mc does so is under
a FIXME), but if someone really does want this back I'll happily apply
the same patch there.

6d51d26a24 Add an extension point to the CommandLine library where clients can
register extra version information to be printed. This is designed to
allow those tools which link in various targets to also print those
registered targets under --version.

Currently this printing logic is embedded into the Support library
directly; a huge layering violation. This is the first step to hoisting
it out into the tools without adding lots of duplicated code.

7c863eb8cc Bugpoint support for miscompilations that result in a crash.
This change allows bugpoint to pinpoint the "opt" pass and bitcode
segment responsible for a crash caused by miscompilation. At least it
works well for me now, without having to create any custom execution
wrappers.

95d206a9c7 In option typo correction, consider -foo=VALUE flags as two distinct parts. The
comments claimed it did this, but the LHS value was actually an unused variable.

The new system considers only the '-foo' part when comparing it for typos
against flags that have values, but still look at the whole string for flags
that don't. That way, we'll still correct '-inst=combine' to '-instcombine'.

e1fee48cd0 PTX: Add intrinsics to list of built-in intrinsics, which allows them to be
used by Clang.  To help Clang integration, the PTX target has been split
     into two targets: ptx32 and ptx64, depending on the desired pointer size.

- Add GCCBuiltin class to all intrinsics
- Split PTX target into ptx32 and ptx64
