The pass adds new kernel arguments for image attributes, and
resolves calls to dummy attribute and resource id getter functions.

This is unused after filtering checks was moved to the clients.
As a result, we can just return the number of the checks in the
precomputed set.
llvm-svn: 244369
This is the full set of checks that clients can further filter. IOW,
it's client-agnostic. This makes LAA complete in the sense that it now
provides the two main results of its analysis precomputed:
1. memory dependences via getDepChecker().getInsterestingDependences()
2. run-time checks via getRuntimePointerCheck().getChecks()
However, as a consequence we now compute this information pro-actively.
Thus if the client decides to skip the loop based on the dependences
we've computed the checks unnecessarily. In order to see whether this
was a significant overhead I checked compile time on SPEC2k6 LTO bitcode
files. The change was in the noise.
The checks are generated in canCheckPtrAtRT, at the same place where we
used to call groupChecks to merge checks.
llvm-svn: 244368
At this point the given Opc must be valid, otherwise we should
not look for a matching pair to form paired load or store.
Thanks to Chad to point out this piece of code!

Summary:
With InstAlias, we don't need to print the _e32 portion of the mnemonic
when we print the $dst operand. This change makes it possible to
include vcc in the asm string when we switch VOPC over to having
implicit vcc defs.

This commit extract the code that parses the 64-bit offset from the method
'parseOperandsOffset' to a new method 'parseOffset' so that we can reuse it
when parsing the offset for the machine memory operands.

Summary: llvm::ConstantFoldTerminator function can convert SwitchInst with single case (and default) to a conditional BranchInst. This patch adds support to preserve make.implicit metadata on this conversion.

This patch fixes the sse2/avx2 vector shift by constant instcombine call to correctly deal with the fact that the shift amount is formed from the entire lower 64-bit and not just the lowest element as it currently assumes.
e.g.
%1 = tail call <4 x i32> @llvm.x86.sse2.psrl.d(<4 x i32> %v, <4 x i32> <i32 15, i32 15, i32 15, i32 15>)
In this case, (V)PSRLD doesn't perform a lshr by 15 but in fact attempts to shift by 64424509455 ((15 << 32) | 15) - giving a zero result.
In addition, this review also recognizes shift-by-zero from a ConstantAggregateZero type (PR23821).

PrettyStackTraceHead is a LLVM_THREAD_LOCAL, which means it's just a global
in LLVM_ENABLE_THREADS=NO builds. If a CrashRecoveryContext is used with
code that uses PrettyStackEntries, and a crash happens, PrettyStackTraceHead is
currently not reset to its pre-crash value. These functions make it possible
to add a cleanup to such code that does this.
(Not reseting the value then causes the assert in ~PrettyStackTraceEntry() to
fire if the code outside of the CrashRecoveryContext also uses
PrettyStackEntries -- for example, clang when building a module.)
Part of PR11974.

llvm-dsymutil has to be able to process debug info produced by other compilers
which use different line table settings. The testcase wasn't generated by
another compiler, but by a modified clang.

Summary: WebAssembly's tablegen instructions have the names WebAssembly expects, but by LLVM convention they're uppercase and suffixed with their type after an underscore. Leave the C++ code that way, but print outt he names WebAssembly expects (lowercase, no type). We could teach tablegen to do this later, maybe by using `!cast<string>(node)` in the .td files.

As a follow-up to r244181, resolve uniquing cycles underneath distinct
nodes on the fly. This prevents uniquing cycles in early operands from
affecting later operands. It also removes an iteration through distinct
nodes' operands.
No real functional change here, just more prompt resolution of temporary
nodes.

The block address machine operands can reference IR blocks in other functions.

This commit removes the 'StringOffset' and 'HasStringValue' fields from the
MIToken struct and simplifies the 'stringValue' method which now returns
the new 'StringValue' field.
This commit also adopts a different way of initializing the lexed tokens -
instead of constructing a new MIToken instance, the lexer resets the old token
using the new 'reset' method and sets its attributes using the new
'setStringValue', 'setOwnedStringValue', and 'setIntegerValue' methods.
