No tests are failing for me, and merging from the trunk only changed text files. Will push my updated tree soon.

Which version of llvm are you using? 3.0 has a known problem with 3-element vectors; I'm using a later version from the trunk.

Yep, I know 3.0 has problems but so far the tests haven't been affected by them. I'll test with llvm trunk.

Pekka Jääskeläinen (pekka-jaaskelainen) wrote :

One test fails also with llvm trunk (x86-64/Debian), but the test which uses the 3-size vecs (which are known to be broken in LLVM 3.0) seems to pass.

I'll add a warning to the configure when using LLVM 3.0 which advises to install LLVM trunk (or 3.1) for more robust OpenCL support.

This test case used to pass, but now breaks with a more recent version of llvm. It seems llvm has a regression in the vector shift operator. I will disable this test until llvm is correct again.
