[swift-dev] problems building swift-3.0-RELEASE

[Jon Rafkind]

I am getting build errors in the clang/ directory when all of the 
swift-related components are checked out to the swift-3.0-RELEASE tag.

First I checked out apple/swift from github, ran utils/update-checkout, 
then checked out each component to use swift-3.0-RELEASE (which I had to 
do manually because update-checkout won't run git pull --tags..)

Anyway the first build error is

swift $ utils/build-script -r

/Users/jonrafkind/tmp/swift3/llvm/tools/clang/utils/TableGen/TableGen.cpp:244:37: 
error: too few arguments to function call, at least argument 'Argv0' 
must be specified
   sys::PrintStackTraceOnErrorSignal();
   ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ^
/Users/jonrafkind/tmp/swift3/llvm/include/llvm/Support/Signals.h:47:3: 
note: 'PrintStackTraceOnErrorSignal' declared here
   void PrintStackTraceOnErrorSignal(StringRef Argv0,


Which I solved by passing in argv[0] to PrintStackTraceOnErrorSignal(). 
Then I got some new errors that I have not attempted to solve.

Thats just a selection of the errors. Which branch of clang/llvm should 
I use to be able to build swift 3.0?
