* [Thumb] Select a BIC instead of AND if the immediate can be encoded more ↵James Molloy2016-06-092-1/+55
| | | | | | | | | | | | | | | | | | | | | | optimally negated If an immediate is only used in an AND node, it is possible that the immediate can be more optimally materialized when negated. If this is the case, we can negate the immediate and use a BIC instead; int i(int a) { return a & 0xfffffeec; } Used to produce: ldr r1, [CONSTPOOL] ands r0, r1 CONSTPOOL: 0xfffffeec And now produces: movs r1, #255 adds r1, #20 ; Less costly immediate generation bics r0, r1 llvm-svn: 272251

* [Sema] Don't crash when a field w/ a mem-initializer clashes with a record nameDavid Majnemer2016-06-092-2/+11
| | | | | | | | | | | It is possible for a field and a class to have the same name. In such cases, performing lookup for the field might return a result set with more than one entry. An overzealous assertion fired, causing us to crash instead of using the non-class lookup result. This fixes PR28060. llvm-svn: 272247

* 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

| | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | 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.
