* [WebAssembly] Add -fwasm-exceptions for wasm EHHeejin Ahn2019-09-121-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This adds `-fwasm-exceptions` (in similar fashion with `-fdwarf-exceptions` or `-fsjlj-exceptions`) that turns on everything with wasm exception handling from the frontend to the backend. We currently have `-mexception-handling` in clang frontend, but this is only about the architecture capability and does not turn on other necessary options such as the exception model in the backend. (This can be turned on with `llc -exception-model=wasm`, but llc is not invoked separately as a command line tool, so this option has to be transferred from clang.) Turning on `-fwasm-exceptions` in clang also turns on `-mexception-handling` if not specified, and will error out if `-mno-exception-handling` is specified.

* [NewPM][Sancov] Create the Sancov Pass after building the pipelinesLeonard Chan2019-09-081-17/+7
| | | | | | | | | | | | | | | | | | | | We're running into linker errors from missing sancov sections: ``` ld.lld: error: relocation refers to a discarded section: __sancov_guards >>> defined in user-arm64-ubsan-sancov-full.shlib/obj/third_party/ulib/scudo/scudo.wrappers_c.cc.o >>> referenced by common.h:26 (../../zircon/third_party/ulib/scudo/common.h:26) ... many other references ``` I believe this is due to a pass in the default pipeline that somehow discards these sections. The ModuleSanitizerCoveragePass was initially added at the start of the pipeline. This now adds it to the end of the pipeline for optimized and unoptimized builds.

* [NewPM][Sancov] Make Sancov a Module Pass instead of 2 PassesLeonard Chan2019-09-041-8/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch merges the sancov module and funciton passes into one module pass. The reason for this is because we ran into an out of memory error when attempting to run asan fuzzer on some protobufs (pc.cc files). I traced the OOM error to the destructor of SanitizerCoverage where we only call appendTo[Compiler]Used which calls appendToUsedList. I'm not sure where precisely in appendToUsedList causes the OOM, but I am able to confirm that it's calling this function *repeatedly* that causes the OOM. (I hacked sancov a bit such that I can still create and destroy a new sancov on every function run, but only call appendToUsedList after all functions in the module have finished. This passes, but when I make it such that appendToUsedList is called on every sancov destruction, we hit OOM.) I don't think the OOM is from just adding to the SmallSet and SmallVector inside appendToUsedList since in either case for a given module, they'll have the same max size. I suspect that when the existing llvm.compiler.used global is erased, the memory behind it isn't freed. I could be wrong on this though. This patch works around the OOM issue by just calling appendToUsedList at the end of every module run instead of function run. The same amount of constants still get added to llvm.compiler.used, abd we make the pass usage and logic simpler by not having any inter-pass dependencies.

* [LTO] Always mark regular LTO units with EnableSplitLTOUnit=1Teresa Johnson2019-07-191-1/+1

In order to avoid spurious errors from LTO when combining with split ThinLTO modules, always set this flag for regular LTO modules.

* [sanitizers] Use covering ObjectFormatType switchesHubert Tong2019-07-191-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This patch removes the `default` case from some switches on `llvm::Triple::ObjectFormatType`, and cases for the missing enumerators (`UnknownObjectFormat`, `Wasm`, and `XCOFF`) are then added. For `UnknownObjectFormat`, the effect of the action for the `default` case is maintained; otherwise, where `llvm_unreachable` is called, `report_fatal_error` is used instead. Where the `default` case returns a default value, `report_fatal_error` is used for XCOFF as a placeholder. For `Wasm`, the effect of the action for the `default` case in maintained. The code is structured to avoid strongly implying that the `Wasm` case is present for any reason other than to make the switch cover all `ObjectFormatType` enumerator values.

* [Clang] Remove unused -split-dwarf and obsolete -enable-split-dwarfAaron Puchert2019-06-261-6/+3
| | | | | | | | | | | | | | | | | | | | | | Summary: The changes in D59673 made the choice redundant, since we can achieve single-file split DWARF just by not setting an output file name. Like llc we can also derive whether to enable Split DWARF from whether -split-dwarf-file is set, so we don't need the flag at all anymore. The test CodeGen/split-debug-filename.c distinguished between having set or not set -enable-split-dwarf with -split-dwarf-file, but we can probably just always emit the metadata into the IR. The flag -split-dwarf wasn't used at all anymore. Reviewers: dblaikie, echristo Reviewed By: dblaikie Differential Revision: https://reviews.llvm.org/D63167 llvm-svn: 364479

* [Clang] Harmonize Split DWARF options with llcAaron Puchert2019-06-151-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: With Split DWARF the resulting object file (then called skeleton CU) contains the file name of another ("DWO") file with the debug info. This can be a problem for remote compilation, as it will contain the name of the file on the compilation server, not on the client. To use Split DWARF with remote compilation, one needs to either * make sure only relative paths are used, and mirror the build directory structure of the client on the server, * inject the desired file name on the client directly. Since llc already supports the latter solution, we're just copying that over. We allow setting the actual output filename separately from the value of the DW_AT_[GNU_]dwo_name attribute in the skeleton CU. Fixes PR40276.

* Initial support for vectorization using MASSV (IBM MASS vector library)Nemanja Ivanovic2019-06-051-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | Part 2 (the Clang portion) of D59881. This patch (first of two patches) enables the vectorizer to recognize the IBM MASS vector library routines. This patch specifically adds support for recognizing the -vector-library=MASSV option, and defines mappings from IEEE standard scalar math functions to generic PowerPC MASS vector counterparts. For instance, the generic PowerPC MASS vector entry for double-precision cbrt function is __cbrtd2_massv. The second patch will further lower the generic PowerPC vector entries to PowerPC subtarget-specific entries. For instance, the PowerPC generic entry cbrtd2_massv is lowered to cbrtd2_P9 for Power9 subtarget. The overall support for MASS vector library is presented as such in two patches for ease of review.

Changes: - Split AddressSanitizer into 2 passes: 1 for the instrumentation on the function, and 1 for the pass itself which creates an instance of the first during it's run. The same is done for AddressSanitizerModule. - Add new PM AddressSanitizer and AddressSanitizerModule. - Add legacy and new PM analyses for reading data needed to initialize ASan with. - Removed DominatorTree dependency from ASan since it was unused. - Move GlobalsMetadata and ShadowMapping out of anonymous namespace since the new PM analysis holds these 2 classes and will need to expose them.
