* Be wary of abnormal exits from loop when exploiting UBSanjoy Das2016-06-093-5/+28
| | | | | | | | | | | | | | We can safely rely on a NoWrap add recurrence causing UB down the road only if we know the loop does not have a exit expressed in a way that is opaque to ScalarEvolution (e.g. by a function call that conditionally calls exit(0)). I believe with this change PR28012 is fixed. Note: I had to change some llvm-lit tests in LoopReroll, since it looks like they were depending on this incorrect behavior. llvm-svn: 272237

* [pdbdump] Verify part of TPI hash streams.Rui Ueyama2016-06-091-0/+28
| | | | | | | | | | | | | | | | | TPI hash table contains a parallel array for the type records. For each type record R, a hash value is calculated by `H(R) % NumBuckets` where H is a hash function, and the result is stored to a bucket element. H is TPI1::hashPrec function in microsoft-pdb repository. Our hash function does not support all type record types yet. Currently it supports only records for line number. I'll extend it in a follow up patch. The aim of verify the hash table is not only detect corrupted files. It ensures that our understanding of how the hash values are calculated is correct. llvm-svn: 272229

| | | | | | | | Without that check it was possible to write test cases where the size was not specified and we ended up with weird asserts down the road, because the default value (1) would not make sense. llvm-svn: 272226

* [RegisterBankInfo] Avoid code duplication in OperandsMapper for the ↵Quentin Colombet2016-06-082-6/+25
| | | | | | | | | | | | | computation of the end of range. Refactor the code so that we do not compute in two different places the end iterator for the range of new virtual registers for a given operand. Although this refactoring was intended as NFC, this is not the case because it actually fixes a bug where we were returning a range off by 1 (too long). Right now, this could not result in an actual bug because we were accessing this range via the BreakDown size of the related operand. llvm-svn: 272208

The patch includes a simple relaxation of the assert to allow constants being of different types, along with a regression test that will provoke the unrelaxed assert.

| | | | | | | | | | | | | | | | | | | | | | | backward-hot-prob consistently. Summary: Consider the following diamond CFG: A / \ B C \/ D Suppose A->B and A->C have probabilities 81% and 19%. In block-placement, A->B is called a hot edge and the final placement should be ABDC. However, the current implementation outputs ABCD. This is because when choosing the next block of B, it checks if Freq(C->D) > Freq(B->D) * 20%, which is true (if Freq(A) = 100, then Freq(B->D) = 81, Freq(C->D) = 19, and 19 > 81*20%=16.2). Actually, we should use 25% instead of 20% as the probability here, so that we have 19 < 81*25%=20.25, and the desired ABDC layout will be generated.

* [DebugInfo] Add calling conventions to DISubroutineTypeReid Kleckner2016-06-083-15/+83
| | | | | | | | | | | | | | | | | | | | | | | Summary: This should have been a very simple change, but it was greatly complicated by the construction of new Decls during IR generation. In particular, we reconstruct the AST function type in order to get the implicit 'this' parameter into C++ method types. We also have to worry about FunctionDecls whose types are not FunctionTypes because CGBlocks.cpp constructs some dummy FunctionDecls with 'void' type.

* [DebugInfo] Add calling convention support for DWARF and CodeViewReid Kleckner2016-06-0821-70/+469
| | | | | | | | | | | | | | | | | | | | | Summary: Now DISubroutineType has a 'cc' field which should be a DW_CC_ enum. If it is present and non-zero, the backend will emit it as a DW_AT_calling_convention attribute. On the CodeView side, we translate it to the appropriate enum for the LF_PROCEDURE record. I added a new LLVM vendor specific enum to the list of DWARF calling conventions. DWARF does not appear to attempt to standardize these, so I assume it's OK to do this until we coordinate with GCC on how to emit vectorcall convention functions.
