2017-05-09Enable TLS support but default to the emulatated TLS model. Enable theMark Kettenis
runtime support code libcompiler_rt for this. This code uses functions that live in libpthread, so code that uses TLS support will need to be linked with -lpthread. This should allow more ports to build with base clang. ok espie@

Requested by deraadt@
2017-03-24Add "supported targets" in lld --help output to be compatible with whatJonathan Gray
libtool generated configure scripts expect. Otherwise they might assume shared libraries aren't supported. From lld svn revisions 298568 and 298571. Discussed with kettenis@
2017-03-24Add "(compatible with GNU linkers)" to the lld version output to avoidJonathan Gray
problems with configure scripts generated with libtool.m4 that would otherwise have to be regenerated with a patched libtool. Among other things this fixes the build of Mesa on arm64 with lld. From lld svn revision 298532. ok kettenis@
2017-03-19Work around a problem where linker-generated symbols are not properlyMark Kettenis
versioned and end up as local symbols despite being explicitly listed as global in the version script. This breaks out brk()/sbrk() implementation. The diff is only a partial solution and unlikely to be accepted as-is upstream. We'll keep it as a local diff until a better solution is found. ok guenther@

From Brad Smith.
2017-02-25Make sure the .eh_frame ends with a terminator. This avoids creating aMark Kettenis
zero-sized .eh_frame section, which confuses the strip from our frankenbinutils. With this diff lld seems to be usable as the arm64 system linker. ok patrick@, jsg@

2017-01-24Handle the OpenBSD-style major/minor shared library version scheme.Mark Kettenis
Don't try to upstream this; we are considering moving to a more standard way that uses symbolic links to point the linker at the right version of shared libraries.

Only having ELF is perfectly fine for us. ok kettenis@
2017-01-21Make LLVM create strict aligned code for OpenBSD/arm64. We currentlyPatrick Wildt
don't enforce it yet, but we want to go down that road. Additionally the Pine64 seems to boot up with strict alignment on by default, so this also implicitly fixes efiboot on that hardware. ok kettenis@ phessler@ visa@

2016-09-05libunwind relies on the EH frame header. Our OpenBSD frontend codePatrick Wildt
does not tell our linker to produce that header for statically linked binaries. Just create that header for all binaries and we are fine. ok guenther@
