* Converting object's error_category to a ManagedStatic to avoid static ↵Chris Bieneman2014-09-191-2/+4

* LTO: introduce object file-based on-disk module format.Peter Collingbourne2014-09-181-0/+2
| | | | | | | | | | | | | | | | | | This format is simply a regular object file with the bitcode stored in a section named ".llvmbc", plus any number of other (non-allocated) sections. One immediate use case for this is to accommodate compilation processes which expect the object file to contain metadata in non-allocated sections, such as the ".go_export" section used by some Go compilers [1], although I imagine that in the future we could consider compiling parts of the module (such as large non-inlinable functions) directly into the object file to improve LTO efficiency.

* Added forgotten noexcept.Abramo Bagnara2014-08-181-1/+1

* Remove unused and odd code.Rafael Espindola2014-06-131-9/+0
| | | | | | | | This code was never being used and any use of it would look fairly strange. For example, it would try to map a object_error::parse_failed to std::errc::invalid_argument. llvm-svn: 210912
* Don't import error_category into the llvm namespace.Rafael Espindola2014-06-121-2/+2

* Use std::error_code instead of llvm::error_code.Rafael Espindola2014-06-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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++. llvm-svn: 210687
* Mark a few functions noexcept.Rafael Espindola2014-06-101-2/+2
| | | | | | This reduces the difference between std::error_code and llvm::error_code. llvm-svn: 210591
* Use an enum class.Rafael Espindola2014-06-031-4/+4

* There is no std::errc::success, remove the llvm one.Rafael Espindola2014-05-311-1/+1
| | | | llvm-svn: 209960
* Support: Make error_category's constructor publicJustin Bogner2014-03-151-4/+4
| | | | | | | | Since our error_category is based on the std one, we should have the same visibility for the constructor. This also allows us to avoid using the _do_message implementation detail in our own categories. llvm-svn: 203998

* Don't convert object_error's enum to and from int.Rafael Espindola2013-06-181-4/+4
| | | | | | | This allows the compiler to see the enum and warn about it. While in here, fix a switch to not use a default and fix style violations. llvm-svn: 184186
