flag as it was a Mach-O universal file.
The default as to which architecture slice that is dumped without an -arch flag
depends on the host architecture and the contents of the universal file. The
malformed archive 00000031.a file has both an x86_64 and i386 slice. So for
for x86_64 hosts only that slice is dumped, for non-x86_64 hosts, which is many
of the bots both slices are dumped.
The test is intended to only check that the malformation of the x86_64 which
has a non-decimal characters in the size field of the archive header so it no
longer crashes.
The problem turned out that the i388 slice of the malformed archive had a
different malformation which was causing the non-x86_64 bots to get this error:
llvm-objdump -macho -disassemble -arch i386 00000031.a
Archive : .00000031.a
00000031.a(c_start.o):
LLVM ERROR: Symbol name entry points before beginning or past end of file.
and causing the test as it was written to fail. So by adding ‘-arch x86_64’ it
should correct the test and the malformation on the i388 slice will not be
dumped.
Also the removal of the malformed-machos mem-crup-0261.macho was not causing
the issue so that is put back in.
Sorry for the churn on these tests, Kev

Summary:
Add an iterator that can walk across blocks and which visits the state
transitions rather than state ranges, with explicit transitions to -1
indicating the presence of top-level calls that may throw and cause the
current function to unwind to caller. This will simplify code that needs
to identify nested try regions.
Refactor SEH and C++EH table generation to use the new
InvokeStateChangeIterator, and remove the InvokeLabelIterator they were
using.

BSD's DSO files have undefined symbol "__progname" which is defined
in crt1.o. On that system, both user programs and system shared
libraries depend on each other.
In general, we need to put symbols defined by user programs which are
referenced by shared libraries to user program's .dynsym.

Summary:
/usr/lib/debug doesn't exist on Windows so there's no point even
attempting to look for symbol files in there.

What was done:
1) .got.plt section is created for functions that requires PLT. .got.plt has 3 predefined empty entries now that are required for dynamic linker.
Also other new items created are configured to have correct jump to PLT[N].
2) PLT section now has PLT[0] entry, also others ones are configured to support PLT->GOT(.got.plt) calls.
3) Implemented .rel[a].plt sections (based on patch http://reviews.llvm.org/D13569).
4) Fixed plt relocations types (based on patch http://reviews.llvm.org/D13589).
NOTES:
The .plt.got zero entry is still empty now. According to ELF specification it should hold the address of the dynamic structure, referenced with the symbol
_DYNAMIC. The _DYNAMIC entry points to the .dynamic section which contains information used by the ELF interpreter to setup the binary.

Now all Target<Arch> classes are used only in Target.cpp.
We can put them in an anonymous namespace. In order to avoid
merge conflict with other people's patches, I'll do that later.
llvm-svn: 250168
This is what most people want anyways. Clang -cc1's main() will override
this but for other tools this is the most sensible default and avoids
some work.

As discussed in D13348 - the INSERTQI range combining code is wrong in that it confuses the insertion bit index with an extraction bit index.
The remaining legal combines are very unlikely (especially once we've converted to shuffles in D13348) so I'm removing the optimization.

Now that all the known faults with GlobalsAA have been fixed, flip the big switch on -enable-non-lto-gmr again.
Feel free to pester me with any more bugs found, and don't hesitate to flip the switch back off.
llvm-svn: 250157
Weak linkage and friends allow a symbol to be overriden outside the
code generator's model, so GlobalsAA shouldn't assume that anything it
can compute about such a symbol is valid.

Summary:
This adds platform code without the cmake/gmake glue to the existing infrastructure.
The missing and incompatibility ptrace(2) bits (existing in FreeBSD) are under active research and development and will be submitted once verified to work.
This code was tested to build and run on NetBSD-current/amd64.
Proper build scripts will be integrated separately as a new commit.

Now LLVMBitWriter compiles without implicit ilist iterator conversions.
In these cases, the cleanest thing was to switch to range-based for
loops. Since there wasn't much noise I converted sub-loops and parent
loops as a drive-by.

In a later commit, `SplitBinaryAdd` will be used outside `IsConstDiff`,
so lift that out. And lift out `IsConstDiff` as
`computeConstantDifference` to keep things clean and to avoid playing
C++ access specifier games.

Continuing the work from last week to remove implicit ilist iterator
conversions. First related commit was probably r249767, with some more
motivation in r249925. This edition gets LLVMTransformUtils compiling
without the implicit conversions.
No functional change intended.

The comment says this was stopped because it was unlikely to be
profitable. This is not true if you want to combine vector loads
with multiple components.
For a simple case that looks like
t0 = load t0 ...
t1 = load t0 ...
t2 = load t0 ...
t3 = load t0 ...
t4 = store t0:1, t0:1
t5 = store t4, t1:0
t6 = store t5, t2:0
t7 = store t6, t3:0
We want to get all of these stores onto a chain
that is a TokenFactor of these N loads. This mostly
solves the AMDGPU merge-stores.ll regressions
with -combiner-alias-analysis for merging vector
stores of vector loads.

context (but otherwise at the top level) to be disabled, to support use of C++
standard library implementations that (legitimately) mark their <blah.h>
headers as being C++ headers from C libraries that wrap things in 'extern "C"'
a bit too enthusiastically.
