* Windows: Use GetModuleHandleEx instead of LoadLibraryDavid Majnemer2013-10-131-2/+2
| | | | | | | | | | | | | | | | | | | | We were using an anti-pattern of: - LoadLibrary - GetProcAddress - FreeLibrary This is problematic because of several reasons: - We are holding on to pointers into a library we just unloaded. - Calling LoadLibrary results in an increase in the reference count of the library in question and any libraries that it depends on and so-on and so-forth. This is none too quick. Instead, use GetModuleHandleEx with GET_MODULE_HANDLE_EX_FLAG_PIN. This is done because because we didn't bring the reference for the library into existence and therefor shouldn't count on it being around later. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192550 91177308-0d34-0410-b5e6-96231b3b80d8

* Windows: Be more explicit with Win32 APIsDavid Majnemer2013-10-074-15/+33
| | | | | | | | | | | | | This addresses several issues in a similar vein: - Use the Unicode APIs when possible, running nm on clang shows that we only use Unicode APIs except for FormatMessage, CreateSemaphore, and GetModuleHandle. AFAICT, the latter two are coming from MinGW and not LLVM itself. - Make getMainExecutable more resilient. It previously considered return values of zero from ::GetModuleFileNameA to be acceptable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192096 91177308-0d34-0410-b5e6-96231b3b80d8

* Windows: Add support for unicode command linesDavid Majnemer2013-10-066-83/+148
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 non-blocking Wait() for launched processesTareq A. Siraj2013-10-011-61/+52
| | | | | | | | | | | | | | | | | | - New ProcessInfo class to encapsulate information about child processes. - Generalized the Wait() to support non-blocking wait on child processes. - ExecuteNoWait() now returns a ProcessInfo object with information about the launched child. Users will be able to use this object to perform non-blocking wait. - ExecuteNoWait() now accepts an ExecutionFailed param that tells if execution failed or not. These changes will allow users to implement basic process parallel tools.

* Support ANSI escape code on WindowsNico Rieck2013-09-111-1/+13
| | | | | | | | In some cases (e.g. when a build system pipes stderr) the Windows console API cannot be used to color output. For these, provide a way to switch to ANSI escape codes. This is required for Clang's -fansi-escape-codes option. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190460 91177308-0d34-0410-b5e6-96231b3b80d8
* Add getenv() wrapper that works on multibyte environment variable.Rui Ueyama2013-09-103-56/+104
| | | | | | | | | | | | | | | | | | 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.

* On Windows, autolink advapi32 from Path.inc for CryptAcquireContextWReid Kleckner2013-08-071-0/+4
| | | | | | | | | | | This allows llvm-tblgen to link successfully when compiling with clang. Both MSBuild and CMake will automatically add advapi32 as part of a set of other dlls comprising the win32 API to the link line, but CMake doesn't do that when compiling with clang. Until someone adds that info to cmake upstream, this seems like a reasonable work around. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187907 91177308-0d34-0410-b5e6-96231b3b80d8
