* Resubmit "[pdb] Allow zero-copy read support for symbol streams.""Zachary Turner2016-05-275-11/+18
| | | | | | | | | Due to differences in template instantiation rules, it is not portable to static_assert(false) inside of an invalid specialization of a template. Instead I just =delete the method so that it can't be used, and leave a comment that it must be explicitly specialized. llvm-svn: 271027

* Don't generate unnecessary signed ConstantRange during multiply. NFCPete Cooper2016-05-271-0/+7
| | | | | | | | | | | | | | r231483 taught ConstantRange::multiply to be clever about signed vs unsigned ranges. For example, an unsigned range could be full-set while the signed range is more specific than that. In looking at the allocations trace for LTO'ing verify-uselistorder (see r236629 for details), millions of allocations are from APInt, many of which come from ConstantRange's. This change tries to avoid some (3.2 million) allocations by returning the unsigned range if its suitable. The checks here are that it should not be a wrapping range, and should be positive. That should be enough to check for ranges such as [1, 10) which the signed range will be equal to, if we were to calculate it.

* [RewriteStatepointsForGC] All constant should have null base pointerIgor Laevsky2016-05-271-8/+16
| | | | | | | | | | | | | | | | | | Currently we consider that each constant has itself as a base value. I.e "base(const) = const". This introduces couple of problems when we are trying to avoid reporting constants in statepoint live sets: 1. When querying "base( phi(const1, const2) )" we will get "phi(const1, const2)" as a base pointer. Since it's not a constant we will record it in a stack map. However on practice we don't want this to happen (constant are never relocated). 2. base( phi(const, gc ptr) ) = phi( const, base(gc ptr) ). This particular case imposes challenge on our runtime - we don't expect to see constant base pointers other than null. This problems can be avoided by treating all constant as if they were derived from null pointer base. I.e in a first case we will not include constant pointer in a stack map at all. In a second case we will get "phi(null, base(gc ptr))" as a base pointer which is a lot more convenient. Differential Revision: http://reviews.llvm.org/D20584 llvm-svn: 270993
* [AMDGPU][llvm-mc] Square-braced-syntax for registers - make ":expr2" optional.Artem Tamazov2016-05-271-6/+10
| | | | | | | | | | | | | | | | | Register numbers may be specified as assembly-time expressions. This feature can be useful in macros and alike. However, expressions are supported within sqare braces only. Sqare braces were initially intended to support specifying of multiple (pairs/quads...) registers. Syntax like v[8:8] which specifies single register is also supported. That allows expressions but looks a bit unnatural. This change supports syntax REG[EXPR]. Tests added.
