There have been a number of tickets related to dll-split on armhf. I have verified that the linker is being invoked. The fixes introduced in #9873 also seem to be present.

More investigation needed.

dll-split crashing usually just means the stage2 compiler is broken somehow, it may be good to start by running the test suite.

comment:2 Changed 3 years ago by erikd

@rwbarton : With this failure to build dll-split the stage2 compiler isn't complete, so how do I run the test suite?

comment:3 Changed 3 years ago by rwbarton

If dll-split was built then the stage2 compiler has also been built, since dll-split is built with the stage2 compiler. It's just the dll-split check and perhaps some libraries that did not get built yet, but you can run the test suite without those.

A checkout of the ghc-7.10 branch (commit f6c690ba64) with these cherry-picked commits:

5d5abdca31     llvmGen: move to LLVM 3.6 exclusively
56fbc18e13     Commit missing T10148 files and ignore the built executable.

and commit that fixes some, aclocal.m4 and distrib/ issues does not suffer from this ddl-split issue.

This is also reminiscent of #9920 where the fix was to either patch the llvm-3.5 sources or move to llvm-3.6.

comment:6 Changed 3 years ago by erikd

Its seems to that @bgamari is is using llvm-3.5.1 where I have been using the llvm-3.5 package from Debian (which seems to be llvm-3.5.0 with about 30 patches applied). Since ticket #9920 actually has the arm-lower-tail-calls.patch patch as an attachment, that patch could probably be added the Debian's llvm package, but that doesn't solve the problem on non-Debian systems.

What we need now is a way to detect this llvm bug at configure time. I'm working on that.

Resolution: duplicate
Status: newclosed

The patch to detect this at configure time is in #10329 and Phab:D856 .
