* Finishing touch for the std::error_code transition.Rafael Espindola2014-06-13
| | | | | | | | | | | While std::error_code itself seems to work OK in all platforms, there are few annoying differences with regards to the std::errc enumeration. This patch adds a simple llvm enumeration, which will hopefully avoid build breakages in other platforms and surprises as we get more uses of std::error_code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210920 91177308-0d34-0410-b5e6-96231b3b80d8

* Use std::error_code instead of llvm::error_code.Rafael Espindola2014-06-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The idea of this patch is to turn llvm/Support/system_error.h into a transitional header that just brings in the erorr_code api to the llvm namespace. I will remove it shortly afterwards. The cases where the general idea needed some tweaking: * std::errc is a namespace in msvc, so we cannot use "using std::errc". I could add an #ifdef, but there were not that many uses, so I just added std:: to them in this patch. * Template specialization had to be moved to the std namespace in this patch set already. * The msvc implementation of default_error_condition doesn't seem to provide the same transformations as we need. Not too surprising since the standard doesn't actually say what "equivalent" means. I fixed the problem by keeping our old mapping and using it at error_code construction time. Despite these shortcomings I think this is still a good thing. Some reasons: * The different implementations of system_error might improve over time. * It removes 925 lines of code from llvm already. * It removes 6313 bytes from the text segment of the clang binary when it is built with gcc and 2816 bytes when building with clang and libstdc++. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210687 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix most of PR10367.Rafael Espindola2014-05-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the design of GlobalAlias so that it doesn't take a ConstantExpr anymore. It now points directly to a GlobalObject, but its type is independent of the aliasee type. To avoid changing all alias related tests in this patches, I kept the common syntax @foo = alias i32* @bar to mean the same as now. The cases that used to use cast now use the more general syntax @foo = alias i16, i32* @bar. Note that GlobalAlias now behaves a bit more like GlobalVariable. We know that its type is always a pointer, so we omit the '*'. For the bitcode, a nice surprise is that we were writing both identical types already, so the format change is minimal. Auto upgrade is handled by looking through the casts and no new fields are needed for now. New bitcode will simply have different types for Alias and Aliasee. One last interesting point in the patch is that replaceAllUsesWith becomes smart enough to avoid putting a ConstantExpr in the aliasee. This seems better than checking and updating every caller. A followup patch will delete getAliasedGlobal now that it is redundant. Another patch will add support for an explicit offset. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@209007 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | Before this patch they would take an boolean argument to say if the path already existed.

Instead, pass in a boolean flag to say if the previous (non-)existence should be an error or not. Callers of the of the old simple versions are not affected. They still ignore the previous (non-)existence as they did before. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201979 91177308-0d34-0410-b5e6-96231b3b80d8

* [asan] rewrite asan's stack frame layoutKostya Serebryany2013-12-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Rewrite asan's stack frame layout. First, most of the stack layout logic is moved into a separte file to make it more testable and (potentially) useful for other projects. Second, make the frames more compact by using adaptive redzones (smaller for small objects, larger for large objects). Third, try to minimized gaps due to large alignments (this is hypothetical since today we don't see many stack vars aligned by more than 32). The frames indeed become more compact, but I'll still need to run more benchmarks before committing, but I am sking for review now to get early feedback. This change will be accompanied by a trivial change in compiler-rt tests to match the new frame sizes.

* Implement categories for special case lists.Peter Collingbourne2013-07-09
| | | | | | | | | | | | | | | | | | | | | | | | A special case list can now specify categories for specific globals, which can be used to instruct an instrumentation pass to treat certain functions or global variables in a specific way, such as by omitting certain aspects of instrumentation while keeping others, or informing the instrumentation pass that a specific uninstrumentable function has certain semantics, thus allowing the pass to instrument callers according to those semantics. For example, AddressSanitizer now uses the "init" category instead of global-init prefixes for globals whose initializers should not be instrumented, but which in all other respects should be instrumented. The motivating use case is DataFlowSanitizer, which will have a number of different categories for uninstrumentable functions, such as "functional" which specifies that a function has pure functional semantics, or "discard" which indicates that a function's return value should not be labelled.

* Completely refactor the structuring of unittest CMake files to match theChandler Carruth2012-06-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Makefiles, the CMake files in every other part of the LLVM tree, and sanity. This should also restore the output tree structure of all the unit tests, sorry for breaking that, and thanks for letting me know. The fundamental change is to put a CMakeLists.txt file in the unittest directory, with a single test binary produced from it. This has several advantages: - No more weird directory stripping in the unittest macro, allowing it to be used more readily in other projects. - No more directory prefixes on all the source files. - Allows correct and precise use of LLVM's per-directory dependency system. - Allows use of the checking logic for source files that have not been added to the CMake build. This uncovered a file being skipped with CMake in LLVM and one in Clang's unit tests. - Makes Specifying conditional compilation or other custom logic for JIT tests easier. It did require adding the concept of an explicit 'optional' source file to the CMake build so that the missing-file check can skip cases where the file is *supposed* to be missing. =] This is another chunk of refactoring the CMake build in order to make it usable for other clients like CompilerRT / ASan / TSan.
