[msan] Instrument x86.pclmulqdq* intrinsics.

2020-01-27T14:17:30+00:00

Summary: These instructions ignore parts of the input vectors which makes the default MSan handling too strict and causes false positive reports.

Migrate function attribute "no-frame-pointer-elim"="false" to "frame-pointer"="none" as cleanups after D56351

[msan] Remove more attributes from sanitized functions.

2019-10-29T00:57:28+00:00

Summary: MSan instrumentation adds stores and loads even to pure readonly/writeonly functions. It is removing some of those attributes from instrumented functions and call targets, but apparently not enough. Remove writeonly, argmemonly and speculatable in addition to readonly / readnone.

Insert module constructors in a module pass

2019-10-11T08:47:03+00:00

Summary: If we insert them from function pass some analysis may be missing or invalid. Fixes PR42877.

Handle llvm.launder.invariant.group in msan.

2019-10-02T19:53:19+00:00

Summary: [MSan] handle llvm.launder.invariant.group Msan used to give false-positives in class Foo { public: virtual ~Foo() {}; }; // Return true iff *x is set. bool f1(void **x, bool flag); Foo* f() { void *p; bool found; found = f1(&p,flag); if (found) { // p is always set here. return static_cast(p); // False positive here. } return nullptr; } Patch by Ilya Tokar.

MSan: handle callbr instructions

2019-07-03T09:28:50+00:00

Summary: Handling callbr is very similar to handling an inline assembly call: MSan must checks the instruction's inputs. callbr doesn't (yet) have outputs, so there's nothing to unpoison, and conservative assembly handling doesn't apply either.

[IR] Disallow llvm.global_ctors and llvm.global_dtors of the 2-field form in textual format

2019-05-15T02:35:32+00:00

The 3-field form was introduced by D3499 in 2014 and the legacy 2-field form was planned to be removed in LLVM 4.0 For the textual format, this patch migrates the existing 2-field form to use the 3-field form and deletes the compatibility code. test/Verifier/global-ctors-2.ll checks we have a friendly error message. For bitcode, lib/IR/AutoUpgrade UpgradeGlobalVariables will upgrade the 2-field form (add i8* null as the third field).
