Pass vector as multiple parameters (as in python f(*x))
Hi, I want to know if it's possible to pass a vector v=c(x,y,...) to a function f(x,y,...) so that each vector element corresponds to a formal argument of the function. For python programmers: f(*v). Specifically, what I'm trying to achieve is: given a list of coordinates l=list(c(x1,y1,z1), c(x2,y2,z2),...) I would like to obtain the corresponding elements in some array A (3-dim in this

...else here can help. Hm, please could we also have the %V asm constraint modifier? That allows us to emit calls to the thunks from inline asm using the register that the compiler chose for us: asm volatile ("call __x86_indirect_thunk_%V[thunk_target]" : : [thunk_target] "r" (the_function)); Other than that, I get the following errors with LLVM+Clang master, and my tree at http://git.infradead.org/users/dwmw2/linux-retpoline.git/shortlog/refs/heads/ibpb I haven't paid much attention to llvmlinux for a while; are these expected? I'll try turning off config options until...

retpoline mitigation and 6.0
I've landed the patch in r324449. Before we merge this into two different Clang release branches and almost immediately release one of them, I would really like someone to confirm that this patch works well with the Linux kernel. David, if you're up for that, it would be great. Alternatively, Guenter or someone else here can help. On Tue, Feb 6, 2018 at 5:59 PM Chandler Carruth
