* Finishing touch for the std::error_code transition.Rafael Espindola2014-06-13
| | | | | | | | | | | While std::error_code itself seems to work OK in all platforms, there are few annoying differences with regards to the std::errc enumeration. This patch adds a simple llvm enumeration, which will hopefully avoid build breakages in other platforms and surprises as we get more uses of std::error_code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210920 91177308-0d34-0410-b5e6-96231b3b80d8

* Use std::error_code instead of llvm::error_code.Rafael Espindola2014-06-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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++. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210687 91177308-0d34-0410-b5e6-96231b3b80d8

This also required making the TimeValue string much more useful. First, there is a standard format for writing out a date and time. Let's use that rather than strings that would have to be parsed. Second, actually output the nanosecond resolution that timevalue claims to have.

* Fix RWMutex to be thread-safe when pthread_rwlock is not availableMark Seaborn2014-03-01
| | | | | | | | | | | | | | lib/Support/RWMutex.cpp contains an implementation of RWMutex that uses pthread_rwlock, but when pthread_rwlock is not available (such as under NaCl, when using newlib), it silently falls back to using the no-op definition in lib/Support/Unix/RWMutex.inc, which is not thread-safe. Fix this case to be thread-safe by using a normal mutex.

| | | | | | | | | | | | | | | Before this patch they would take an boolean argument to say if the path already existed. This was redundant with the returned error_code which is able to represent that. This allowed for callers to incorrectly check only the existed flag instead of first checking the error code. Instead, pass in a boolean flag to say if the previous (non-)existence should be an error or not. Callers of the of the old simple versions are not affected. They still ignore the previous (non-)existence as they did before. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201979 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix configure to find arc4random via header files.Todd Fiala2014-02-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ISSUE: On Ubuntu 12.04 LTS, arc4random is provided by libbsd.so, which is a transitive dependency of libedit. If a system had libedit on it that was implemented in terms of libbsd.so, then the arc4random test, previously implemented as a linker test, would succeed with -ledit. However, on Ubuntu this would also require a #include <bsd/stdlib.h>. This caused a build breakage on configure-based Ubuntu 12.04 with libedit installed. FIX: This fix changes configure to test for arc4random by searching for it in the standard header files. On Ubuntu 12.04, this test now properly fails to find arc4random as it is not defined in the default header locations. It also tweaks the #define names to match the output of the header check command, which is slightly different than the linker function check #defines. I tested the following scenarios: (1) Ubuntu 12.04 without the libedit package [did not find arc4random, as expected] (2) Ubuntu 12.04 with libedit package [properly did not find arc4random, as expected] (3) Ubuntu 12.04 with most recent libedit, custom built, and not dependent on libbsd.so [properly did not find arc4random, as expected]. (4) FreeBSD 10.0B1 [properly found arc4random, as expected] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200819 91177308-0d34-0410-b5e6-96231b3b80d8

This patch makes that the case also for non-thread builds and adds a very basic unit test to check it. (This was causing PR18205 because PrettyStackTraceHead didn't get zero- initialized and we'd crash trying to read past the end of that list.

* Windows: Add support for unicode command linesDavid Majnemer2013-10-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: The MSVCRT deliberately sends main() code-page specific characters. This isn't too useful to LLVM as we end up converting the arguments to UTF-16 and subsequently attempt to use the result as, for example, a file name. Instead, we need to have the ability to access the Unicode command line and transform it to UTF-8. This has the distinct advantage over using the MSVC-specific wmain() function as our entry point because: - It doesn't work on cygwin. - It only work on MinGW with caveats and only then on certain versions. - We get to keep our entry point as main(). :) N.B. This patch includes fixes to other parts of lib/Support/Windows s.t. we would be able to take advantage of getting the Unicode paths. E.G. clang spawning clang -cc1 would want to give it Unicode arguments.

* Add getenv() wrapper that works on multibyte environment variable.Rui Ueyama2013-09-10
| | | | | | | | | | | | | | | | | | On Windows, character encoding of multibyte environment variable varies depending on settings. The only reliable way to handle it I think is to use GetEnvironmentVariableW(). GetEnvironmentVariableW() works on wchar_t string, which is on Windows UTF16 string. That's not ideal because we use UTF-8 as the internal encoding in LLVM. This patch defines a wrapper function which takes and returns UTF-8 string for GetEnvironmentVariableW(). The wrapper function does not do any conversion and just forwards the argument to getenv() on Unix.

* [conf] Add config variable to disable crash related overrides.Daniel Dunbar2013-08-30
| | | | | | | | | | | | | | | | | | | | | - We do some nasty things w.r.t. installing or overriding signal handlers in order to improve our crash recovery support or interaction with crash reporting software, and those things are not necessarily appropriate when LLVM is being linked into a client application that has its own ideas about how to do things. This gives those clients a way to disable that handling at build time. - Currently, the code this guards is all Apple specific, but other platforms might have the same concerns so I went for a more generic configure name. Someone who is more familiar with library embedding on Windows can handle choosing which of the Windows/Signals.inc behaviors might make sense to go under this flag. - This also fixes the proper autoconf'ing of ENABLE_BACKTRACES. The code expects it to be undefined when disabled, but the autoconf check was just defining it to 0. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189694 91177308-0d34-0410-b5e6-96231b3b80d8
