* [esan|wset] EfficiencySanitizer working set tool fastpathDerek Bruening2016-05-251-0/+104
| | | | | | | | | | | | | | | | | Summary: Adds fastpath instrumentation for esan's working set tool. The instrumentation for an intra-cache-line load or store consists of an inlined write to shadow memory bits for the corresponding cache line. Adds a basic test for this instrumentation.

* [PGO] Add flags to control IRPGO warnings.Rong Xu2016-05-131-3/+18
| | | | | | | | | | | | | Currently there is no reasonable way to control the warnings in the 'use' phase of the IRPGO pass. This is problematic because the output can be somewhat spammy. This patch adds some flags which allow us to optionally disable these warnings. The current upstream behavior will remain the default.

| | | | | | | | | | | | | instrumentation generates a COMDAT symbol __llvm_profile_raw_version to overwrite the same symbol in profile run-time to distinguish IR profiles from Clang generated profiles.

They had target specific test in generic directories without the correct specifiers and made it hard for us to come up with a good solution by rapidly committing untested changes.

* [PGO] Fix __llvm_profile_raw_version linkage in MACHORong Xu2016-05-091-1/+1
| | | | | | | | | | | | | | | | | | | IR instrumentation generates a COMDAT symbol __llvm_profile_raw_version to overwrite the same symbol in profile run-time to distinguish IR profiles from Clang generated profiles. In MACHO, LinkOnceODR linkage is used due to the lack of COMDAT support. But LinkOnceODR linkage might have .weak_def_can_be_hidden assembly directive, while the weak variable in run-time has a .weak_definition directive. Linker will not merge these two symbols even they have the same name. The end result is IR profiles are not properly flagged in MACHO. This patch changes the linkage for __llvm_profile_raw_version in each module to LinkOnceAny so that it has same .weak_definition directive as in the run-time.

* [MSan] [AArch64] Fix vararg helper for >1 or non-int fixed arguments.Marcin Koscielnicki2016-05-091-3/+13
| | | | | | | | | | | | | | | | | | This fixes http://llvm.org/PR27646 on AArch64. There are three issues here: - The GR save area is 7 words in size, instead of 8. This is not enough if none of the fixed arguments is passed in GRs (they're all floats or aggregates). - The first argument is ignored (which counteracts the above if it's passed in GR). - Like x86_64, fixed arguments landing in the overflow area are wrongly counted towards the overflow offset.

* [ASan] Add shadow offset for SystemZ.Marcin Koscielnicki2016-04-301-2/+8
| | | | | | | | | | | | | | | | | | | | | | SystemZ on Linux currently has 53-bit address space. In theory, the hardware could support a full 64-bit address space, but that's not supported due to kernel limitations (it'd require 5-level page tables), and there are no plans for that. The default process layout stays within first 4TB of address space (to avoid creating 4-level page tables), so any offset >= (1 << 42) is fine. Let's use 1 << 52 here, ie. exactly half the address space. I've originally used 7 << 50 (uses top 1/8th of the address space), but ASan runtime assumes there's some space after the shadow area. While this is fixable, it's simpler to avoid the issue entirely. Also, I've originally wanted to have the shadow aligned to 1/8th the address space, so that we can use OR like X86 to assemble the offset. I no longer think it's a good idea, since using ADD enables us to load the constant just once and use it with register + register indexed addressing.
