# Progress #

TCWG-845 Static linking missing linker defined symbols
- Now upstream

TCWG-829 Support for ifunc
- Patch sent upstream for review, no feedback yet. This is a bit messy
as ARM is different to other architectures so I expect this to need
reworking several times.

TCWG-828 Static linking and TLS
- Downstream patch implemented and tested, will send upstream after ifunc

TCWG-683 Support for branches to undefined weak references
- Downstream patch implemented and tested

Other:
- Downloaded and built Mozilla and Chromium so I can use them as
performance tests for lld (initially for x86_64).
- Wrote some scripts to make using lld in place of gnu ld a bit more convenient.

# Plan #
- Upstream static linking changes
- Work some infrastructure to test lld more widely on ARM.

Hello,

Is there any instruction / manual for compiling linaro tool chain under cygwin?

Is there any instruction / manual for compiling linaro tool chain under cygwin?

We do our windows mingw32 builds under Linux, using cross compilers.
We don't do builds on windows. In theory, a build should work under
cygwin as they work on linux, but we don't test that. In practice,
you might run into a few issues that will need to be worked around.

We use a tool called ABE for building toolchains. You can find info on ABE here
https://wiki.linaro.org/ABE
