* Introduce `sanitizer_malloc_introspect_t` for Darwin which is a sub-class of ↵Dan Liew2018-11-081-1/+23
| | | | | | | | | | | | | | | | | | | | | | Darwin's `malloc_introspection_t` and use it when setting up the malloc zone. Summary: Currently `sanitizer_malloc_introspection_t` just adds a version field which is used to version the allocator ABI. The current allocator ABI version is returned by the new `GetMallocZoneAllocatorEnumerationVersion()` function. The motivation behind this change is to allow external processes to determine the allocator ABI of a sanitized process. rdar://problem/45284065 Reviewers: kubamracek, george.karpenkov, vitalybuka Subscribers: #sanitizers, llvm-commits Differential Revision: https://reviews.llvm.org/D54045 git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@346420 91177308-0d34-0410-b5e6-96231b3b80d8

* [CMake][ASan][HWASan] Set an explicit dependency on libc++ headersPetr Hosek2018-11-072-12/+32
| | | | | | | | | | | | | | We have seen failing builds due to a race condition between RTAsan_dynamic and libc++ headers builds, specifically libc++ headers depend on __config and if this header hasn't been copied into the final location, including other headers will typically result in failure. To avoid this race, we add an explicit dependency on libc++ headers which ensures that they've been copied into place before the sanitizer object library build starts.

* [XRay] Use TSC delta encoding for custom/typed eventsDean Michael Berris2018-11-073-69/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This change updates the version number for FDR logs to 5, and update the trace processing to support changes in the custom event records. In the runtime, since we're already writing down the record preamble to handle CPU migrations and TSC wraparound, we can use the same TSC delta encoding in the custom event and typed event records that we use in function event records. We do the same change to typed events (which were unsupported before this change in the trace processing) which now show up in the trace. Future changes should increase our testing coverage to make custom and typed events as first class entities in the FDR mode log processing tools. This change is also a good example of how we end up supporting new record types in the FDR mode implementation. This shows the places where new record types are added and supported. Depends on D54139.

* Adapt UBSan integer truncation tests to NetBSDKamil Rytarowski2018-11-0610-198/+198
| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: The NetBSD headers use internal indirect type for standard *int*_t definitions. The internal type is unrolled inside the sanitizer into e.g. __int32_t from int32_t. This symbol mangling causes pattern mismatch in the interger truncation tests as they expect exact types such as 'int32_t'. Change the pattern rules so every acceptable internal form of *int*_t will be accepted flawlessly.

| | | | | | | | | | | | | | | | | | | | | | | | | Summary: For platforms without preinit support (such as NetBSD/amd64) the initialization routine __xray_init() was called in non-deterministic order compared to other constructors. This caused breakage failures as xray routines attempted to execute code with assumption of being initialized, which was no always true. Use GCC/Clang extension to set maximal priority to the constructor calling __xray_init(). This code switches away from C++ lambda form, as it did not allow to specify this compiler extension.

* [XRay] Update XRayRecord to support Custom/Typed EventsDean Michael Berris2018-11-067-34/+41
| | | | | | | | | | | | | | | | | | | | | | | | | Summary: This change cuts across LLVM and compiler-rt to add support for rendering custom events in the XRayRecord type, to allow for including user-provided annotations in the output YAML (as raw bytes). This work enables us to add custom event and typed event records into the `llvm::xray::Trace` type for user-provided events. This can then be programmatically handled through the C++ API and can be included in some of the tooling as well. For now we support printing the raw data we encounter in the custom events in the converted output. Future work will allow us to start interpreting these custom and typed events through a yet-to-be-defined API for extending the trace analysis library.

* [Sanitizers] Disable SANITIZER_CAN_FAST_UNWIND on all SPARC targetsRainer Orth2018-11-052-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While testing my to-be-submitted Solaris sanitizer support on gcc mainline, I ran into an issue on Solaris/SPARC (sparc-sun-solaris2.11). Initially libasan.so failed to link: Undefined first referenced symbol in file __sanitizer::BufferedStackTrace::FastUnwindStack(unsigned long, unsigned long, unsigned long, unsigned long, unsigned int) /var/gcc/gcc-9.0.0-20181024/11.5-gcc-gas/sparc-sun-solaris2.11/./libsanitizer/asan/.libs/libasan.so This happens because SANITIZER_CAN_FAST_UNWIND is enabled on non-Linux SPARC targets (cf. sanitizer_stacktrace.h), but the guard around the SPARCv8-only definition in sanitizer_stacktrace_sparc.cc only works with clang: clang predefines __sparcv8__ on non-Solaris, and __sparcv8 only on Solaris gcc predefines __sparcv8 on Solaris, but __sparc_v8__ on non-Solaris The attached patch allows for all three variants. However, disabling SANITIZER_CAN_FAST_UNWIND on all SPARC targets fixes a couple of testsuite failures in the Solaris asan testsuite, so for now it's better to keep it disabled everywhere. This allowed the libsanitizer build to complete and gave reasonable (though slightly worse than on Solaris/x86) testsuite results.

* [Sanitizers] Solaris largefile fixesRainer Orth2018-11-054-19/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While testing the Solaris libsanitizer port on GCC mainline, I found that I'd messed up the largefile checks in various ways, some of which showed as compile failures (wrong structure sizes and member offsets), others at runtime, some of those only on sparc as a big-endian target. This patch fixes all of them: - OFF_T is now correctly defined for 32-bit largefile and traditional environments, and 64-bit. - The definition of __sanitizer_dirent now checks the correct conditionals. - sanitizer_procmaps_solaris.cc undefines _FILE_OFFSET_BITS: before Solaris 11.4 <procfs.h> doesn't even compile with largefile support enabled, but the use at hand doesn't need it anyway while g++ 9 will define _FILE_OFFSET_BITS=64 out of the box. - With full largefile support enabled, one needs to use e.g. mmap64 instead of mmap; this is hidden behind macros. With this patch I could bootstrap gcc mainline on both sparc-sun-solaris2.11 and i386-pc-solaris2.11. In addition, I've successfully built llvm on i386-pc-solaris2.11.

* [XRay] Update TSC math to handle wraparoundDean Michael Berris2018-11-054-81/+132
| | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Prior to this change, we can run into situations where the TSC we're getting when exiting a function is less than the TSC we got when entering it. This would sometimes cause the counter for cumulative call times overflow, which was erroneously also being stored as a signed 64-bit integer. This change addresses both these issues while adding provisions for tracking CPU migrations. We do this because moving from one CPU to another doesn't guarantee that the timestamp counter for some architectures aren't guaranteed to be synchronised. For the moment, we leave the provisions there until we can update the data format to include the counting of CPU migrations we can catch. We update the necessary tests as well, ensuring that our expectations for the cycle accounting to be met in case of counter wraparound.

Summary: The motivation here is to be able support initialisation of the malloc zone on other code paths. rdar://problem/45284065 Reviewers: kubamracek, george.karpenkov Subscribers: llvm-commits, #sanitizers Differential Revision: https://reviews.llvm.org/D54037 git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@345983 91177308-0d34-0410-b5e6-96231b3b80d8
* [XRay] Update delta computations in runtimeDean Michael Berris2018-11-022-5/+39
| | | | | | | | | | | | | | | | | | Summary: Fix some issues discovered from mostly manual inspection of outputs from the `llvm-xray fdr-dump` tool. It turns out we haven't been writing the deltas properly, and have been writing down zeros for deltas of some records. This change fixes this oversight born by the recent refactoring.

* [XRay] Fix TSC and atomic custom/typed event accountingDean Michael Berris2018-11-016-12/+134
| | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This is a follow-on change to D53858 which turns out to have had a TSC accounting bug when writing out function exit records in FDR mode. This change adds a number of tests to ensure that: - We are handling the delta between the exit TSC and the last TSC we've seen. - We are writing the custom event and typed event records as a single update to the buffer extents. - We are able to catch boundary conditions when loading FDR logs. We introduce a TSC matcher to the test helpers, which we use in the testing/verification of the TSC accounting change.

* [XRay] Add CPU ID in Custom Event FDR RecordsDean Michael Berris2018-11-013-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This change cuts across compiler-rt and llvm, to increment the FDR log version number to 4, and include the CPU ID in the custom event records. This is a step towards allowing us to change the `llvm::xray::Trace` object to start representing both custom and typed events in the stream of records. Follow-on changes will allow us to change the kinds of records we're presenting in the stream of traces, to incorporate the data in custom/typed events. A follow-on change will handle the typed event case, where it may not fit within the 15-byte buffer for metadata records. This work is part of the larger effort to enable writing analysis and processing tools using a common in-memory representation of the events found in traces. The work will focus on porting existing tools in LLVM to use the common representation and informing the design of a library/framework for expressing trace event analysis as C++ programs.

* Compile and test i128 math builtins for Win64Reid Kleckner2018-11-0139-48/+104
| | | | | | | | | | | | | | | | | | | | | Summary: Windows has always been LLP64, not LP64, so the macros were incorrect. Check for _WIN64, since AArch64 sets that too. The tests have to be fixed up in two main ways: 1. Use 'ULL' suffixes to avoid sign extension when passing hex literals with the sign bit set to signed 128 arguments. Clang -fms-compatibility makes such hex literals signed, not unsigned. 2. Disable various tests for 80-bit long double interoperation with i128 values.
