Uh-oh. :)
So, I don't think the ABI should matter much to the native register context. What matters here is the registers and their sizes. I'm guessing the N32 thing is something like the x32 intel abi, wher all registers are 64-bit, but sizeof(void*) is 32-bit. In that case this function will not work correctly, as it will detect it as 32-bit (but the NT_PRSTATUS-based one would, I guess). Does N32 work on pre-3.13 kernels? (Grepping the source seems to find mentions of it, but i don't know how well it actually worked). I guess is back to drawing board with this one again. Could you please send me the contents of the N32 auxiliary vector (LD_SHOW_AUXV as well as the actual binary contents). I presume the one you sent me earlier was O32. cheers, pl http://reviews.llvm.org/D20368 _______________________________________________ lldb-commits mailing list lldb-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-commits
