| | | | | | | | | | | As on other hosts, the CPU identification instruction is priveleged, so we need to look through /proc/cpuinfo. I copied the PowerPC way of handling "generic".

* Expose install_fatal_error_handler() through the C API.Filip Pizlo2013-10-17
| | | | | | | | | | | | | | | | | | | I expose the API with some caveats: - The C++ API involves a traditional void* opaque pointer for the fatal error callback. The C API doesn’t do this. I don’t think that the void* opaque pointer makes any sense since this is a global callback - there will only be one of them. So if you need to pass some data to your callback, just put it in a global variable. - The bindings will ignore the gen_crash_diag boolean. I ignore it because (1) I don’t know what it does, (2) it’s not documented AFAIK, and (3) I couldn’t imagine any use for it. I made the gut call that it probably wasn’t important enough to expose through the C API. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192864 91177308-0d34-0410-b5e6-96231b3b80d8

* Path: Recognize Windows compiled resource file.Rui Ueyama2013-10-15
| | | | | | | | | | | | | | Some background: One can pass compiled resource files (.res files) directly to the linker on Windows. If a resource file is given, the linker will run "cvtres" command in background to convert the resource file to a COFF file to link it. What I'm trying to do with this patch is to make the linker to recognize the resource file by file magic, so that it can run cvtres command.

* Windows: Use GetModuleHandleEx instead of LoadLibraryDavid Majnemer2013-10-13
| | | | | | | | | | | | | | | | | | | | 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 Majnemer2013-10-07
| | | | | | | | | | | | | 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 Majnemer2013-10-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 non-blocking Wait() for launched processesTareq A. Siraj2013-10-01
| | | | | | | | | | | | | | | | | | - 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.

| | | | | | | | | | | | Based on code review feedback from Eric Christopher, unshifting these constants as they can appear in the gdb_index itself, shifted a further 24 bits.
