I’m looking at that pull request currently, thanks for the link.
Here is the output of readelf -r for libswiftcore, test.swift (as compiled) and test.swift.
Thanks for looking into this! - Will

Nick was correct in noting that __muloti4 wasn’t needed on 32-bit platforms. I added another case to the preprocessor conditional for __muloti4, and specified __arm__ and __linux__ for mulodi4. The __multi3 and __divti3 references went away.
Then, I went on to the module.map file for bringing in the Glibc headers. I’m trying to think of a way to either remove the architecture specific paths to many of those libraries (they’re now x86_64-linux-gnu, but need to be arm-linux-gnueabihf for arm). I read the modules documentation at http://clang.llvm.org/docs/Modules.html and it doesn’t look like it’s possible to have conditionals in there. I’m considering whether it’s a good idea to preprocess that file in some way to fill them out with the correct paths in the build scripts. I went ahead and changed them all (breaking x86_64 for the time being).
Did you try https://github.com/apple/swift/pull/282 ?
At this point, the compiler and standard library are all built, and I think I have one final issue. In the testing suite, the binaries generated by the swift compiler don’t run. They’re emitting unexpected reloc type errors. It appears that reolc type 0x03 is R_ARM_REL32 which is not permitted for use with shared libraries:
CollectionOfOne.swift.tmp/a.out: error while loading shared libraries: /home/wdillon/build/Ninja-ReleaseAssert/swift-linux-armv7/lib/swift/linux/libswiftCore.so: unexpected reloc type 0x03
This also happens with small example swift programs that I’ve written for testing.
+John for this error.
It would be also helpful if you could find which code contains theserelocations. Try 'objdump -R libswiftCore.so' or 'readelf -r'.Dmitri-- main(i,j){for(i=2;;i++){for(j=2;j<i;j++){if(!(i%j)){j=0;break;}}if(j){printf("%d\n",i);}}} /*Dmitri Gribenko <griboz...@gmail.com>*/
