2022-01-26[NFC] Additional header dependency cleanup LLVMSupportserge-sans-paille
A few more forward-declarations, a few less headers. the impact on number of preprocessed lines for LLVMSupport is negligible (-3K lines) but it's always good to remove dependencies. Related discourse thread: https://llvm.discourse.group/t/include-what-you-use-include-cleanup
2022-01-21[llvm] Cleanup header dependencies in ADT and Supportserge-sans-paille
The cleanup was manual, but assisted by "include-what-you-use". It consists in 1. Removing unused forward declaration. No impact expected. 2. Removing unused headers in .cpp files. No impact expected. 3. Removing unused headers in .h files. This removes implicit dependencies and is generally considered a good thing, but this may break downstream builds. I've updated llvm, clang, lld, lldb and mlir deps, and included a list of the modification in the second part of the commit. 4. Replacing header inclusion by forward declaration. This has the same impact as 3. Notable changes: - llvm/Support/TargetParser.h no longer includes llvm/Support/AArch64TargetParser.h nor llvm/Support/ARMTargetParser.h - llvm/Support/TypeSize.h no longer includes llvm/Support/WithColor.h - llvm/Support/YAMLTraits.h no longer includes llvm/Support/Regex.h - llvm/ADT/SmallVector.h no longer includes llvm/Support/MemAlloc.h nor llvm/Support/ErrorHandling.h You may need to add some of these headers in your compilation units, if needs be. As an hint to the impact of the cleanup, running clang++ -E -Iinclude -I../llvm/include ../llvm/lib/Support/*.cpp -std=c++14 -fno-rtti -fno-exceptions | wc -l before: 8000919 lines after: 7917500 lines Reduced dependencies also helps incremental rebuilds and is more ccache friendly, something not shown by the above metric :-) Discourse thread on the topic: https://llvm.discourse.group/t/include-what-you-use-include-cleanup/5831

I've left out some cases where I wasn't totally sure this was right or whether the include was ok (compiler-rt) or idiomatic (flang).

2019-09-18[Support] Replace function with function_ref in writeFileAtomically. NFCIlya Biryukov
Summary: The latter is slightly more efficient and communicates the intent of the API: writeFileAtomically does not own or copy the callback, it merely calls it at some point.

2019-01-19Update the file headers across all of the LLVM projects in the monorepoChandler Carruth
to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636

This compiles with no changes to clang/lld/lldb with MSVC and includes overloads to various functions which are used by those projects and llvm which have OwningPtr's as parameters. This should allow out of tree projects some time to move. There are also no changes to libs/Target, which should help out of tree targets have time to move, if necessary. llvm-svn: 203083

2012-12-03Use the new script to sort the includes of every file under lib.Chandler Carruth
Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] llvm-svn: 169131
2012-02-09Change default error_code ctor to a 'named ctor' so it's more self-documenting.David Blaikie
Unify default construction of error_code uses on this idiom so that users don't feel compelled to make static globals for naming convenience. (unfortunately I couldn't make the original ctor private as some APIs don't return their result, instead using an out parameter (that makes sense to default construct) - which is a bit of a pity. I did, however, find/fix some cases of unnecessary default construction of error_code before I hit the unfixable cases) llvm-svn: 150197
