| * TableGen: Refactor AsmWriterEmitter to keep AsmWriterInsts.Ahmed Bougacha2013-10-281-26/+26
| | | | | | | | | | | | | | | | These used to be referenced by the CGI->AWI map (in AsmWriterEmitter), but stored in a vector local to EmitPrintInstruction. Move the vector to AsmWriterEmitter too. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193525 91177308-0d34-0410-b5e6-96231b3b80d8
| * lit: multiprocessing platform fix attemptAlp Toker2013-10-281-1/+2
| | | | | | | | | | | | | | | | | | | | The error raised by Python varies by platform(!), so let's just catch any exception and fall back. Thanks to Sylvestre Ledru for noticing this on a Debian / Python 2.7 system running code coverage. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193516 91177308-0d34-0410-b5e6-96231b3b80d8

| * lit: Issue a note when multiprocessing fails to loadAlp Toker2013-10-261-0/+1
| | | | | | | | | | | | | | | | | | | | If multiprocessing was requested, detected as available and subsequently failed to initialize it's worth letting the user know about it before falling back to threads. This condition can arise in certain OpenBSD / FreeBSD Python versions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193465 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | This should be a better fix for lit multiprocessing failures, replacing the OpenBSD and FreeBSD workarounds in r193413 and r193457.

| * Windows: Add support for unicode command linesDavid Majnemer2013-10-063-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
