When a virtual register is live across a call, limit the search space to
call-preserved registers.

parser now at least tries to generate IR for the

Creating the isPredicated TSFlag enables the code
to use the property defined in the instruction format
instead of using a large switch statement.

llvm-svn: 150078

Build an ordered vector of register mask operands (i.e., calls) when
computing live intervals. Provide a checkRegMaskInterference() function
that computes a bit mask of usable registers for a live range.

This is a quick way of determining of a live range crosses any calls,
and restricting it to the callee saved registers if it does.
Previously, we had to discover call clobbers for each candidate register
independently.

I added the full testing for all possible pseudo-ops of cmp.
I extended X86AsmPrinter.cpp and X86IntelInstPrinter.cpp.

You'l also see lines alignments (unrelated to this fix) in X86IselLowering.cpp from my previous check-in.

not a constant expression, because we can't tell whether the complete class type
will have an overloaded operator&.

Clarify that contributors are agreeing to license their code under the 
license corresponding to the subproject that they are contributing to,
as requested by a potential contributor.

Also, as a drive-by, update the llvm-gcc/GPL section to mention dragonegg
and say that GPL code is all in its own repo's.

Remove GCC builtins for vpermilp* intrinsics as clang no longer needs them. Custom lower the intrinsics to the vpermilp target specific node and remove intrinsic patterns.

the sign bit doesn't have undefined behavior, but a signed left shift of a 1 bit
out of the sign bit still does. As promised to Howard :)

The suppression of the potential constant expression checking in system headers
is also removed, since the problem it was working around is gone.

Also, provide and use accessors for the thread options on breakpoints so we
can control sending the appropriate events.

This is a great warning, but it was observed that a ton of real world code violates
it all the time for (semi-)legitimate reasons.  This warnings is fairly pedantic, which is good,
but not for everyone.  For example, there is a fair amount of idiomatic code out there
that does "default: abort()", and similar idioms.

information about the current frame rather than
the debug information about "this" and "self"
when determining the types of those pointers.
This allows expressions to work in frames that
don't have valid "this" and "self" pointers,
working around poor debug information.
