[LLVMdev] Optimising bit-flipping code
Hi,
I'm compiling a large code base that uses tagged data, with the tag in the
two lowest bits.
I.e. ints are shifted two steps to the left and have 2 in the tag bits,
pointers have 0 in the tag bits, etc.
When I compile the code, I notice that there are places where -O3 doesn't
remove
unnecessary tag bit tests and manipulations, when they are performed with
bitwise
manipulation (which

[LLVMdev] generate llvm.assume calls in GVN?
Would it be wrong to generate the llvm.assume IR suggested below? in GVN?
Given more info via the AssumptionCache, InstCombine can then do more
optimizing.

can''t start xend
Hi,
I''m running a recent fedora-compiled xen kernel and the libs that
come with it.
I''m unable to start xend. I''ve tracked down the problem to the fact
that
xen.lowlevel.xc seems to be unable to talk to xen via /proc/xen/
privcmd.
When I run the test program below, I get a "function not implemented"
which I think results from the fact that an ioctl
