[LLVMdev] running test-suite in cross compilation/execution

[reed kotler]

Currently, if you are on Mips hardware running linux, you can basically 
just run test suite the same way you would run it on an x86 box.

You can just do a "make report TEST=simple" for example.

We also run it on an x86 box, generating MIPS code and then use either 
qemu as a simulator or connect to a mips linux box to just execute the 
tests.

To do this cross compilation and testing, we have made our own 
TEST.xxx... scripts that are heavily customized. We have made other 
modifications to various files in test-suite. I'm not sure the total 
extent but it takes some work each time we resynch it all to the tip of 
tree.

I want to push all of this into the LLVM trunk in some intelligent way 
so that it's consistent with what is already there and so that people 
that are outside of Mips can just check out an LLVM/Clang tree and build 
the compiler and run test-suite.

Is Apple already doing this for compiling test-suite on x86 for ARM/IOS 
and then running it on an iphone or ipad?

If so, how is this setup up. I.e.
make TEST=..................

?????

What is the intention here?

To me, no files should need to be customized as long as the 
functionality matches one the ones already in test-suite.

If we do need to put back target specific TEST.xxx files, then maybe 
there should be target subdirectories for those.
