Hi JZr,
how hard could it be to add support for tls-direct-seg-refs? It should allow
the compiler to generate more efficient code. I think I need to do more
staring into the TLS spec to understand why it doesn't work for us at the
moment...
Cheers,
Jiri

Předmět: [HelenOS-devel] Heads up: Changing crosscompiler target for amd64
"In order to fix clang build on amd64, I'm changing its target from
amd64-linux-gnu to amd64-unknown-elf. The reason for this is that
clang doesn't support "-mno-tls-direct-seg-refs", which is necessary
for HelenOS to work when using a Linux target. It's an OS-specific
optimization, so changing target to unknown fixes the issue.
There are no known regressions at this moment, but you'll need to
rebuild your amd64 crosscompiler. After this, build using clang should
produce a working system.
