The parameter already requires the toolchain, sink the method into the class.
This also enables the use of the distro detection logic which will be needed to
support Exherbo's multiarch approach.

Convert the cascading if/else to a switch. This makes it easier to follow the
logic. Minor difference is that we no longer default to x86_64 but rather to
the architecture specified by the architecture.

This patch adds Size member to SectionPiece so that getRangeAndSize
can just return a SectionPiece instead of a std::pair<SectionPiece *, uint_t>.
Also renamed the function.
llvm-svn: 270346
We were using std::pair to represents pieces of splittable section
contents. It hurt readability because "first" and "second" are not
meaningful. This patch give them names.
One more thing is that piecewise liveness information is stored to
the second element of the pair as a special value of output section
offset. It was confusing, so I defiend a new bit, "Live", in the
new struct.

Ensure _mm256_extract_epi8 and _mm256_extract_epi16 zero extend their i8/i16 result to i32. This matches _mm_extract_epi8 and _mm_extract_epi16.

This fixes a potential bug when cross linking very large executables
on LLP64 machines such as Windows. On such platform, uintX_t is 64 bits
while unsigned is 32 bits.

Most functions take destination buffers as the first arguments
just like memcpy, so this order is easier to read.
Also simplified the function.

This fixes a bug introduced in:
r262115 - CodeGen: Take MachineInstr& in SlotIndexes and LiveIntervals, NFC
The iterator End here might == MBB->end(), and so we can't unconditionally
dereference it. This often goes unnoticed (I don't have a test case that always
crashes, and ASAN does not catch it either) because the function call arguments are
turned right back into iterators. MachineInstrBundleIterator's constructor,
however, does have an assert which might randomly fire.

Main problem here was that SHF_COMPRESSED has the same value with
XCORE_SHF_CP_SECTION, which was included as standart (common) flag.
As far I understand xCore is a family of controllers and it that
means it's constant should be processed separately,
only if e_machine == EM_XCORE, otherwise llvm-readobj would output
different constants twice for compressed section:
Flags [
..
SHF_COMPRESSED (0x800)
..
XCORE_SHF_CP_SECTION (0x800)
..
]
what probably does not make sence if you're not working with xcore file.

In one of the already existing apps that I'm testing TSan on, I really see a mutex path that is longer than 10 (but not by much, something like 11-13 actually). Let's raise this to 20 and weaken the assertion so we don't crash.

A cleanuppad is not cheap, they turn into many instructions and result
in additional spills and fills. It is not worth keeping a cleanuppad
around if all it does is hold a lifetime.end instruction.
N.B. We first try to merge the cleanuppad with another cleanuppad to
avoid dropping the lifetime and debug info markers.

Allocating larger register classes first should give better allocation
results (and more importantly for myself, make the lit tests more stable
with respect to scheduler changes).

The InductiveRangeCheck struct is only five words long; so passing these
around value is fine. The allocator makes the code look more complex
than it is.

I had used `std::remove_if` under the assumption that it moves the
predicate matching elements to the end, but actaully the elements
remaining towards the end (after the iterator returned by
`std::remove_if`) are indeterminate. Fix the bug (and make the code
more straightforward) by using a temporary SmallVector, and add a test
case demonstrating the issue.
