* tsan: fix signal handling in ignored librariesDmitry Vyukov2016-02-234-6/+145
| | | | | | | | | | | | | | The first issue is that we longjmp from ScopedInterceptor scope when called from an ignored lib. This leaves thr->in_ignored_lib set. This, in turn, disables handling of sigaction. This, in turn, corrupts tsan state since signals delivered asynchronously. Another issue is that we can ignore synchronization in asignal handler, if the signal is delivered into an IgnoreSync region. Since signals are generally asynchronous, they should ignore memory access/synchronization/interceptor ignores. This could lead to false positives in signal handlers. llvm-svn: 261658
* Remove an unnecessary workaround introduced in r259975. (NFC)Adrian Prantl2016-02-231-12/+9
| | | | | | | | | | | | | | | | Now that LLVM r259973 allows replacing a temporary type with another temporary we can rely on the original implementation. It is possible for enums to be created as part of their own declcontext. In this case a FwdDecl will be created twice. This doesn't cause a problem because both FwdDecls are entered into the ReplaceMap: finalize() will replace the first FwdDecl with the second and then replace the second with complete type. Thanks to echristo for pointing this out. llvm-svn: 261657
* [WinEH] Don't inline an 'unwinds to caller' cleanupret into funclets which ↵David Majnemer2016-02-232-0/+86
| | | | | | | | | | | | | | | | | | | | | locally unwind It is problematic if the inlinee has a cleanupret which unwinds to caller and we inline it into a call site which doesn't unwind. If the funclet unwinds anywhere other than to the caller, then we will give the funclet two unwind destinations. This will result in a verifier failure. Seeing as how the caller wasn't an invoke (which would locally unwind) and that the funclet cannot unwind to caller, we must conclude that an 'unwind to caller' cleanupret is dynamically unreachable. This fixes PR26698. Differential Revision: http://reviews.llvm.org/D17536 llvm-svn: 261656

* [lld] [ELF/AArch64] Fix R_AARCH64_ABS64 in Shared modeAdhemerval Zanella2016-02-235-11/+90
| | | | | | | | | | | | | | This patch fixes the R_AARCH64_ABS64 relocation when used in shared mode, where it requires a dynamic R_AARCH64_RELATIVE relocation. To correct set the addend on the dynamic relocation (since it will be used by the dynamic linker), a new TargetInfo specific hook was created (getDynRelativeAddend) to get the correct addend based on relocation type. The patch fixes the issues when creating shared library code against {init,fini}_array, where it issues R_AARCH64_ABS64 relocation against local symbols. llvm-svn: 261651

* Work around a stepping bug in arm64 android MPavel Labath2016-02-237-95/+354
| | | | | | | | | | | | | | | | | | | | | Summary: On arm64, linux<=4.4 and Android<=M there is a bug, which prevents single-stepping from working when the system comes back from suspend, because of incorrectly initialized CPUs. This did not really affect Android<M, because it did not use software suspend, but it is a problem for M, which uses suspend (doze) quite extensively. Fortunately, it seems that the first CPU is not affected by this bug, so this commit implements a workaround by forcing the inferior to execute on the first cpu whenever we are doing single stepping. While inside, I have moved the implementations of Resume() and SingleStep() to the thread class (instead of process).

* [PM] Remove an overly aggressive assert now that I can actually test theChandler Carruth2016-02-232-1/+32
| | | | | | | | | | | | | | | | | pattern that triggers it. This essentially requires an immutable function analysis, as that will survive anything we do to invalidate it. When we have such patterns, the function analysis manager will not get cleared between runs of the proxy. If we actually need an assert about how things are queried, we can add more elaborate machinery for computing it, but so far I'm not aware of significant value provided. Thanks to Justin Lebar for noticing this when he made a (seemingly innocuous) change to FunctionAttrs that is enough to trigger it in one test there. Now it is covered by a direct test of the pass manager code. llvm-svn: 261627
