2019-08-05Rename F_{None,Text,Append} to OF_{None,Text,Append}. NFCFangrui Song1-2/+2
F_{None,Text,Append} are kept for compatibility since r334221. llvm-svn: 367800
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
2018-12-19Let TableGen write output only if it changed, instead of doing so in cmake, ↵Nico Weber1-8/+24
attempt 2 This relands r330742: """ Let TableGen write output only if it changed, instead of doing so in cmake. Removes one subprocess and one temp file from the build for each tablegen invocation. No intended behavior change. """ In particular, if you see rebuilds after this change that you didn't see before this change, that's unintended and it's fine to revert this change again (but let me know). r330742 got reverted because some people reported that llvm-tblgen ran on every build after it. This could happen if the depfile output got deleted without deleting the main .inc output. To fix, make TableGen always write the depfile, but keep writing the main .inc output only if it has changed. This matches what we did in cmake before.

2018-05-07Revert r330742: Let TableGen write output only if it changed, instead of ↵Chandler Carruth1-16/+5
doing so in cmake. This change causes us to re-run tablegen for every single target on every single build. This is much, much worse than the problem being fixed AFAICT. On my system, it makes a clean rebuild of `llc` with nothing changed go from .5s to over 8s. On systems with less parallelism, slower file systems, or high process startup overhead this will be even more extreme. The only way I see this could be a win is in clean builds where we churn the filesystem. But I think incremental rebuild is more important, and so if we want to re-instate this, it needs to be done in a way that doesn't trigger constant re-runs of tablegen. llvm-svn: 331702
2018-05-01Remove \brief commands from doxygen comments.Adrian Prantl1-1/+1
We've been running doxygen with the autobrief option for a couple of years now. This makes the \brief markers into our comments redundant. Since they are a visual distraction and we don't want to encourage more \brief markers in new code either, this patch removes them all.

2017-12-28Avoid int to string conversion in Twine or raw_ostream contexts.Benjamin Kramer1-1/+1
Some output changes from uppercase hex to lowercase hex, no other functionality change intended. llvm-svn: 321526
2017-09-23[Support] Rename tool_output_file to ToolOutputFile, NFCReid Kleckner1-2/+2
This class isn't similar to anything from the STL, so it shouldn't use the STL naming conventions. llvm-svn: 314050

2014-08-25Modernize raw_fd_ostream's constructor a bit.Rafael Espindola1-10/+10
Take a StringRef instead of a "const char *". Take a "std::error_code &" instead of a "std::string &" for error. A create static method would be even better, but this patch is already a bit too big. llvm-svn: 216393

This should make sure that most new uses use the std prefix. llvm-svn: 210835
2014-06-12Remove system_error.h.Rafael Espindola1-1/+1
This is a minimal change to remove the header. I will remove the occurrences of "using std::error_code" in a followup patch. llvm-svn: 210803

2014-03-06Replace OwningPtr<T> with std::unique_ptr<T>.Ahmed Charles1-2/+1
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

llvm-svn: 202957
2014-02-24Replace the F_Binary flag with a F_Text one.Rafael Espindola1-2/+2
After this I will set the default back to F_None. The advantage is that before this patch forgetting to set F_Binary would corrupt a file on windows. Forgetting to set F_Text produces one that cannot be read in notepad, which is a better failure mode :-) llvm-svn: 202052
2014-02-24Don't make F_None the default.Rafael Espindola1-2/+2
This will make it easier to switch the default to being binary files. llvm-svn: 202042

2013-03-20Make sure TableGen exits with an error code after printing errors.Jakob Stoklund Olesen1-2/+5
This makes it possible to report multiple errors in one invocation. There are already calls to PrintError in CodeGenDAGPatterns.cpp which previously would not cause TableGen to fail. <rdar://problem/13463339> llvm-svn: 177573
2013-02-07tblgen: Diagnose duplicate includes.Sean Silva1-4/+4
A double inclusion will pretty much always be an error in TableGen, so there's no point going on just to die with "def already defined" or whatnot. I'm not too thrilled about the "public: ... private: ..." to expose the DependenciesMapTy, but I really didn't see a better way to keep that type centralized. It's a smell that indicates that some refactoring is needed to make this code more loosely coupled. This should avoid all bugs of the same nature as PR15189. llvm-svn: 174582
2012-10-25Remove exception handling usage from tblgen.Joerg Sonnenberger1-49/+39
Most places can use PrintFatalError as the unwinding mechanism was not used for anything other than printing the error. The single exception was CodeGenDAGPatterns.cpp, where intermediate errors during type resolution were ignored to simplify incremental platform development. This use is replaced by an error flag in TreePattern and bailout earlier in various places if it is set. llvm-svn: 166712

2012-10-03tblgen: Put new TableGenMain API in place.Sean Silva1-0/+19
In order to avoid rev-lock with Clang when moving to the new API, also preserve the current API temporarily and insert a shim to implement the new API in terms of the old. llvm-svn: 165165

2011-10-04tblgen: add preprocessor as a separate modeChe-Liang Chiou1-0/+23
This patch adds a preprocessor that can expand nested for-loops for saving some copy-n-paste in *.td files. The preprocessor is not yet integrated with TGParser, and so it has no direct effect on *.td inputs. However, you may preprocess an td input (and only preprocess it). To test the proprecessor, type: tblgen -E -o $@ $< llvm-svn: 141079
