Hi, the ARM backend lacks some stuff like support for atomic intrinsics. I learned the hard way (crash). Lately I was told that the ARM backend of LLVM is generally in its early stages of development. I would like to know more about this. Which stuff is missing, known to be unstable and the like. Thanks in advance for taking the time. Regards Robert -------------- next part -------------- A

I want to use llvm inside OpenJDK's runtime hotspot for which a variant exists that uses llvm as a JIT compiler backend.

Hi, I have reworked my previous example and got something which is accepted by tblgen: let isCall = 1, Defs = [R0, R1, R2, R3, R12, LR, D0, D1, D2, D3, D4, D5, D6, D7, CPSR] in { def ARM_ATOMIC_CMP_SWAP : ABXI<0b1011, (outs GPR:$dst), (ins i32imm:$ptr, i32imm:$old, i32imm:$new), "do_something", [(set GPR:$dst, (atomic_cmp_swap_32

Hi, I am missing atomic operations support for the ARM backend (see PR #3887) and started trying to implement them. Since this is the first time that I work on such stuff (and llvm) I am going to take the supposedly easy route and provide an implementation that will work on Linux systems. This involves calling a special function which the kernel handles itself. Details here:
