2022-12-07Add support for a backdoor driver option that enables emitting headerAkira Hatanaka1-10/+126
usage information in JSON to a file Each line in the file is a JSON object that has the name of the main source file followed by the list of system header files included directly or indirectly from that file. For example: {"source":"/tmp/foo.c", "includes":["/usr/include/stdio.h", "/usr/include/stdlib.h"]} To reduce the amount of data written to the file, only the system headers that are directly included from a non-system header file are recorded. In order to emit the header information in JSON, it is necessary to set the following environment variables: CC_PRINT_HEADERS_FORMAT=json CC_PRINT_HEADERS_FILTERING=only-direct-system The following combination is equivalent to setting CC_PRINT_HEADERS=1: CC_PRINT_HEADERS_FORMAT=textual CC_PRINT_HEADERS_FILTERING=none Differential Revision: https://reviews.llvm.org/D137996

2021-04-14Add flag for showing skipped headers in -H / --show-includes outputHans Wennborg1-0/+16
Consider the following set of files: a.cc: #include "a.h" a.h: #ifndef A_H #define A_H #include "b.h" #include "c.h" // This gets "skipped". #endif b.h: #ifndef B_H #define B_H #include "c.h" #endif c.h: #ifndef C_H #define C_H void c(); #endif And the output of the -H option: $ clang -c -H a.cc . ./a.h .. ./b.h ... ./c.h Note that the include of c.h in a.h is not shown in the output (GCC does the same). This is because of the include guard optimization: clang knows c.h is covered by an include guard which is already defined, so when it sees the include in a.h, it skips it. The same would have happened if #pragma once were used instead of include guards. However, a.h *does* include c.h, and it may be useful to show that in the -H output. This patch adds a flag for doing that. Differential revision: https://reviews.llvm.org/D100480
2021-04-06[SystemZ][z/OS][Windows] Add new OF_TextWithCRLF flag and use this flag ↵Abhina Sreeskantharajan1-1/+1
instead of OF_Text Problem: On SystemZ we need to open text files in text mode. On Windows, files opened in text mode adds a CRLF '\r\n' which may not be desirable. Solution: This patch adds two new flags - OF_CRLF which indicates that CRLF translation is used. - OF_TextWithCRLF = OF_Text | OF_CRLF indicates that the file is text and uses CRLF translation. Developers should now use either the OF_Text or OF_TextWithCRLF for text files and OF_None for binary files. If the developer doesn't want carriage returns on Windows, they should use OF_Text, if they do want carriage returns on Windows, they should use OF_TextWithCRLF. So this is the behaviour per platform with my patch: z/OS: OF_None: open in binary mode OF_Text : open in text mode OF_TextWithCRLF: open in text mode Windows: OF_None: open file with no carriage return OF_Text: open file with no carriage return OF_TextWithCRLF: open file with carriage return The Major change is in llvm/lib/Support/Windows/Path.inc to only set text mode if the OF_CRLF is set. ``` if (Flags & OF_CRLF) CrtOpenFlags |= _O_TEXT; ``` These following files are the ones that still use OF_Text which I left unchanged. I modified all these except raw_ostream.cpp in recent patches so I know these were previously in Binary mode on Windows. ./llvm/lib/Support/raw_ostream.cpp ./llvm/lib/TableGen/Main.cpp ./llvm/tools/dsymutil/DwarfLinkerForBinary.cpp ./llvm/unittests/Support/Path.cpp ./clang/lib/StaticAnalyzer/Core/HTMLDiagnostics.cpp ./clang/lib/Frontend/CompilerInstance.cpp ./clang/lib/Driver/Driver.cpp ./clang/lib/Driver/ToolChains/Clang.cpp Reviewed By: MaskRay Differential Revision: https://reviews.llvm.org/D99426

2020-02-25clang-cl: Add a `/showIncludes:user` flag.Nico Weber1-2/+5
This flag is like /showIncludes, but it only includes user headers and omits system headers (similar to MD and MMD). The motivation is that projects that already track system includes though other means can use this flag to get consistent behavior on Windows and non-Windows, and it saves tools that output /showIncludes output (e.g. ninja) some work. implementation-wise, this makes `HeaderIncludesCallback` honor the existing `IncludeSystemHeaders` bit, and changes the three clients of `HeaderIncludesCallback` (`/showIncludes`, `-H`, `CC_PRINT_HEADERS=1`) to pass `-sys-header-deps` to set that bit -- except for `/showIncludes:user`, which doesn't pass it.

2019-01-19Update the file headers across all of the LLVM projects in the monorepoChandler Carruth1-4/+3
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
2018-05-04[clang-cl] Print /showIncludes to stderr, if used in combination with /E, ↵Erich Keane1-1/+15
/EP or /P This replicates 'cl.exe' behavior and allows for both preprocessor output and dependency information to be extraced with a single compiler invocation. This is especially useful for compiler caching with tools like Mozilla's sccache.

2016-03-23clang-cl: Fix remaining bugs in interaction of /Yc and /FI /showIncludes.Nico Weber1-26/+27
Instead of putting the /Yc header into ExtraDeps, give DependencyOutputOptions a dedicated field for /Yc mode, and let HeaderIncludesCallback hang on to the full DependencyOutputOptions object, not just ExtraDeps. Reverts parts of r263352 that are now no longer needed. llvm-svn: 264182
2016-03-23clang-cl: Include /FI headers in /showIncludes output.Nico Weber1-4/+11
-H in gcc mode doesn't print -include headers, but they are included in depfiles written by MMD and friends. Since /showIncludes is what's used instead of depfiles, printing /FI there seems important (and matches cl.exe). Instead of giving HeaderIncludeGen more options, just switch on ShowAllHeaders in clang-cl mode and let clang::InitializePreprocessor() not put -include flags in the <command line> block. This changes the behavior of -E slightly, and it removes the <command line> flag from the output triggered by setting the obscure CC_PRINT_HEADERS=1 env var to true while running clang. Both of these seem ok to change. http://reviews.llvm.org/D18401 llvm-svn: 264174
2016-03-13clang-cl: Add /Yc argument to /showIncludes output.Nico Weber1-20/+24
To make this work, delay printing of ExtraDeps in HeaderIncludesCallback a bit, so that it happens after CompilerInstance::InitializeSourceManager() has run. General /FI arguments are still missing from /showIncludes output, this still needs to be fixed. llvm-svn: 263352

2015-08-13Add sanitizer blacklists to the rules generated with -M/-MM/-MD/-MMD.Ivan Krasin1-23/+40
Summary: Clang sanitizers, such as AddressSanitizer, ThreadSanitizer, MemorySanitizer, Control Flow Integrity and others, use blacklists to specify which types / functions should not be instrumented to avoid false positives or suppress known failures. This change adds the blacklist filenames to the list of dependencies of the rules, generated with -M/-MM/-MD/-MMD. This lets CMake/Ninja recognize that certain C/C++/ObjC files need to be recompiled (if a blacklist is updated).

2014-07-17clang-cl: Flush stdout after writing the /showIncludes outputEhsan Akhgari1-0/+1
Summary: Before this patch, you could get lines in the output such as: Note: including file: ../../dist/include/js/Tc:/path/to/foo.cpp(1,1) : error(clang): static_assert failed... This patch ensures that the stdout output from showIncludes won't be garbled in the terminal like this, and it also helps applications that use the output to generate dependency information if they happen to capture both stdout and stderr. Test Plan: Tested locally, it's hard to write an automated test for this as the behavior depends on the buffering of the ostreams.
