2017-12-13Remove redundant includes from various places.Michael Zolotukhin

2017-10-02Move the stripping of invalid debug info from the Verifier to AutoUpgrade.Adrian Prantl
This came out of a recent discussion on llvm-dev (https://reviews.llvm.org/D38042). Currently the Verifier will strip the debug info metadata from a module if it finds the dbeug info to be malformed. This feature is very valuable since it allows us to improve the Verifier by making it stricter without breaking bcompatibility, but arguable the Verifier pass should not be modifying the IR. This patch moves the stripping of broken debug info into AutoUpgrade (UpgradeDebugInfo to be precise), which is a much better location for this since the stripping of malformed (i.e., produced by older, buggy versions of Clang) is a (harsh) form of AutoUpgrade. This change is mostly NFC in nature, the one big difference is the behavior when LLVM module passes are introducing malformed debug info. Prior to this patch, a NoAsserts build would have printed a warning and stripped the debug info, after this patch the Verifier will report a fatal error. I believe this behavior is actually more desirable anyway.

2016-11-18Timer: Track name and description.Matthias Braun
The previously used "names" are rather descriptions (they use multiple words and contain spaces), use short programming language identifier like strings for the "names" which should be used when exporting to machine parseable formats. Also removed a unused TimerGroup from Hexxagon.

2016-11-11Split Bitcode/ReaderWriter.h into separate reader and writer headersTeresa Johnson
Summary: Split ReaderWriter.h which contains the APIs into both the BitReader and BitWriter libraries into BitcodeReader.h and BitcodeWriter.h. This is to address Chandler's concern about sharing the same API header between multiple libraries (BitReader and BitWriter). That concern is why we create a single bitcode library in our downstream build of clang, which led to r286297 being reverted as it added a dependency that created a cycle only when there is a single bitcode library (not two as in upstream).

2016-11-08IR, Bitcode: Change bitcode reader to no longer own its memory buffer.Peter Collingbourne
Unique ownership is just one possible ownership pattern for the memory buffer underlying the bitcode reader. In practice, as this patch shows, ownership can often reside at a higher level. With the upcoming change to allow multiple modules in a single bitcode file, it will no longer be appropriate for modules to generally have unique ownership of their memory buffer. The C API exposes the ownership relation via the LLVMGetBitcodeModuleInContext and LLVMGetBitcodeModuleInContext2 functions, so we still need some way for the module to own the memory buffer. This patch does so by adding an owned memory buffer field to Module, and using it in a few other places where it is convenient.

2015-12-17[ThinLTO] Metadata linking for imported functionsTeresa Johnson
Summary: Second patch split out from http://reviews.llvm.org/D14752. Maps metadata as a post-pass from each module when importing complete, suturing up final metadata to the temporary metadata left on the imported instructions. This entails saving the mapping from bitcode value id to temporary metadata in the importing pass, and from bitcode value id to final metadata during the metadata linking postpass. Depends on D14825.

2014-09-03Pass a && to getLazyBitcodeModule.Rafael Espindola

2014-08-26Pass a MemoryBufferRef when we can avoid taking ownership.Rafael Espindola
The attached patch simplifies a few interfaces that don't need to take ownership of a buffer. For example, both parseAssembly and parseBitcodeFile will parse the entire buffer before returning. There is no need to take ownership. Using a MemoryBufferRef makes it obvious in the type signature that there is no ownership transfer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@216488 91177308-0d34-0410-b5e6-96231b3b80d8

2014-06-26Introduce a string_ostream string builder faciltyAlp Toker
string_ostream is a safe and efficient string builder that combines opaque stack storage with a built-in ostream interface. small_string_ostream<bytes> additionally permits an explicit stack storage size other than the default 128 bytes to be provided. Beyond that, storage is transferred to the heap. This convenient class can be used in most places an std::string+raw_string_ostream pair or SmallString<>+raw_svector_ostream pair would previously have been used, in order to guarantee consistent access without byte truncation. The patch also converts much of LLVM to use the new facility. These changes include several probable bug fixes for truncated output, a programming error that's no longer possible with the new interface. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211749 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-26Split out the IRReader header and the utility functions it provides intoChandler Carruth
its own library. These functions are bridging between the bitcode reader and the ll parser which are in different libraries. Previously we didn't have any good library to do this, and instead played fast and loose with a "header only" set of interfaces in the Support library. This really doesn't work well as evidenced by the recent attempt to add timing logic to the these routines. As part of this, make them normal functions rather than weird inline functions, and sink the implementation into the library. Also clean up the header to be nice and minimal. This requires updating lots of build system dependencies to specify that the IRReader library is needed, and several source files to not implicitly rely upon the header file to transitively include all manner of other headers. If you are using IRReader.h, this commit will break you (the header moved) and you'll need to also update your library usage to include 'irreader'. I will commit the corresponding change to Clang momentarily. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177971 91177308-0d34-0410-b5e6-96231b3b80d8
