The type of the immediates should not matter as long as the encoding is
equivalent to the encoding of one of the legal inline constants.

This instructions writes to an 32-bit SGPR.  This change required adding
the 32-bit VCC_LO and VCC_HI registers, because the full VCC register
is 64 bits.

This fixes verifier errors on several of the indirect addressing piglit
tests.

[C++11] Replacing Scope iterators using_directives_begin() and using_directives_end() with iterator_range using_directives(). Updating all of the usages of the iterators with range-based for loops, and removing the no-longer-needed iterator versions.

The "noduplicate" attribute of call instructions is sometimes queried directly
and sometimes through the cannotDuplicate() predicate. This patch streamlines
all queries to use the cannotDuplicate() predicate. It also adds this predicate
to InvokeInst, to mirror what CallInst has.

[sanitizer] reverse the order of the stack traces printed for every pair of locks in the deadlock report (first print the 'from' node, then print the 'to' node of the deadlock graph)

llvm-svn: 204043

[sanitizer] make the deadlock detector print 2*N stack traces on lock-order-inversion with N locks (i.e. print stack traces for both lock acquisitions in every edge in the graph). More improvements to follow

[sanitizer] allow to store the lock context (stack trace id) with all currently held locks in a thread. This will allow the deadlock detector to provide better warnings (more changes to go)

Make behavior introduced in r202820 conditional (under legacy_pthread_cond flag).
The new issue that we've hit with the satellite pthread_cond_t struct is
that pthread_condattr_getpshared does not work (satellite data is not shared between processes).
The idea is that most processes do not use pthread 2.2.5.
The rare ones that use (2.2.5 is dated by 2002) must specify legacy_pthread_cond=1
on their own risk.

This is really a consistency fix. Since given

a = b

we propagate the information, we should propagate it too given

a = b + (1 - 1)

The previous deduping strategy was woefully inadequate - it only
considered the most recent file used and avoided emitting a duplicate in
that case - never considering the a/b/a scenario.

It was also lacking when it came to directory paths as the previous
filename would never match the current if the filename had been split
into file and directory components.

This change builds caching functionality into the line table at the
lowest level in an optional form (a file number of 0 indicates that one
should be chosen and returned) and will eventually be reused by the
normal source level debugging DWARF emission.

- Adds support for inserting vzerouppers before tail-calls.
  This is enabled implicitly by having MachineInstr::copyImplicitOps preserve
  regmask operands, which allows VZeroUpperInserter to see where tail-calls use
  vector registers.

- Fixes a bug that caused the previous version of this optimization to miss some
  vzeroupper insertion points in loops. (Loops-with-vector-code that followed
  loops-without-vector-code were mistakenly overlooked by the previous version).

- New algorithm never revisits instructions.

The gain with multithreading is large, but turning it on requires
an environment variable and so is hard for users to discover.  This
gives users a way to discover the feature by printing out a message
when the environment variable is not set.
