Duncan P. N. Exon Smith 117cf2bd1f InstrProf: Write the __llvm_profile_write_buffer()
Write __llvm_profile_write_buffer(), which uses the same logic as
__llvm_profile_write_file(), but writes directly to a provided `char*`
buffer instead.

Duncan P. N. Exon Smith cf4bb960bd InstrProf: If libc is available, use it; no functionality change
It was misguided to plan to rely on __llvm_profile_write_buffer() in
__llvm_profile_write_file().  It's less complex to duplicate the writing
logic than to mmap the file.

Since it's here to stay, move `FILE*`-based writing logic into
InstrProfilingFile.c.

Duncan P. N. Exon Smith be0a5e176b InstrProf: Reorganize files; no functionality change
Move functions around to prepare for some other changes.

  - Merge InstrProfilingExtras.h with InstrProfiling.h.  There's no
    benefit to having these split.

  - Rename InstrProfilingExtras.c to InstrProfilingFile.c.

  - Split actual buffer writing code out of InstrProfiling.c into
    InstrProfilingBuffer.c.

  - Drive-by corrections of a couple of header comments.

Duncan P. N. Exon Smith 24b4b65339 InstrProf: Read raw binary profile in llvm-profdata
Read a raw binary profile that corresponds to a memory dump from the
runtime profile.

The test is a binary file generated from
cfe/trunk/test/Profile/c-general.c with the new compiler-rt runtime and
the matching text version of the input.  It includes instructions on how
to regenerate.

Justin Bogner b9bd7f85a7 ProfileData: Introduce InstrProfWriter using the naive text format
This isn't a format we'll want to write out in practice, but moving it
to the writer library simplifies llvm-profdata and isolates it from
further changes to the format.

This also allows us to update the tests to not rely on the text output
format.

Justin Bogner f8d791983c ProfileData: Introduce the InstrProfReader interface and a text reader
This introduces the ProfileData library and updates llvm-profdata to
use this library for reading profiles. InstrProfReader is an abstract
base class that will be subclassed for both the raw instrprof data
from compiler-rt and the efficient instrprof format that will be used
for PGO.

Daniel Sanders f88a29e66a [mips] Correct lowering of VECTOR_SHUFFLE to VSHF.
Summary:
VECTOR_SHUFFLE concatenates the vectors in an vectorwise fashion.
  <0b00, 0b01> + <0b10, 0b11> -> <0b00, 0b01, 0b10, 0b11>
VSHF concatenates the vectors in a bitwise fashion:
  <0b00, 0b01> + <0b10, 0b11> ->
  0b0100       + 0b1110       -> 0b01001110
                                 <0b10, 0b11, 0b00, 0b01>
We must therefore swap the operands to get the correct result.

The test case that discovered the issue was MultiSource/Benchmarks/nbench.

Tom Stellard def38c567d R600/SI: Use SGPR_(32|64) reg clases when lowering SI_ADDR64_RSRC
The SReg_(32|64) register classes contain special registers in addition
to the numbered SGPRs.  This can lead to machine verifier errors when
these register classes are used as sub-registers for SReg_128, since
SReg_128 only uses the numbered SGPRs.

Replacing SReg_(32|64) with SGPR_(32|64) fixes this problem, since
the SGPR_(32|64) register classes contain only numbered SGPRs.

Tests cases for this are comming in a later commit.

Alexey Samsonov 089d130568 [CMake] Propagate top-level targets for compiler-rt runtimes and test-suites
from (external) compiler-rt build tree into LLVM/Clang build tree in
LLVM_BUILD_EXTERNAL_COMPILER_RT mode.

For instance, running
  make asan -j12
in LLVM/Clang build tree will now build Clang, use it to configure
compiler-rt build tree, and invoke "make asan -j12" there. ASan runtime will
be built in the proper location, where Clang driver expects to find it.

Running
  make check-asan
will build Clang, use it to configure compiler-rt build tree, build everything
there, and then run "make check-asan" in compiler-rt build tree using just-built
Clang and ASan runtime.
