<br>
I could not find a list for swift-corelibs-xctest so I am posting it here.<br>
<br>
I am trying to run tests based on XCTest (<a href="https://github.com/apple/swift-corelibs-xctest" rel="noreferrer" target="_blank">https://github.com/apple/<wbr>swift-corelibs-xctest</a>) using LLVM's JIT.<br>
Everything is working good so far. However, I am getting a crash.<br>
Based on a shallow investigation I can see that this is somehow related to the way Swift treats the command line arguments. Or, to be more precise, to the way I pass the arguments to the swift's 'main' function.<br>
<br>
What I did so far is not different from what I do to run C or C++ using JIT:<br>
<br>
auto main = ((int (*)(int, const char **))(intptr_t)mainPointer);<br>
const int argc = 1;<br>
const char *argv[] = { "some-name", NULL };<br>
auto result = main(argc, argv);<br>
<br>
Based on what I see in the IR[1] the 'argv' has type "%Sp = type <{ i8* }>", which seems to be a struct with a pointer to something.<br>
<br>
So the question is: what is being passed as a second argument to the 'main' function of a swift program?<br>
<br>
Any other advice on JIT-ting Swift are more than welcome :)<br>
