...or' is a really nice pass, and can infer more precise and useful attributes, which may give more opportunities for optimization. But we shouldn't depend on 'attributor' to correct wrong function attributes, because we cannot run 'attributor' after every pass, right?

...****************************************** So if function attribute 'argmemonly' on function @foo is correct, then there's a bug in pass 'ipsccp'. When it replaces the function local value with global variable, then it shoud remember to remove this function attribute.

Hi Fangqing, llvm::itaniumDemangle() doesn't yet provide this functionality, but I'm working on adding it in now for the LLDB folks (http://lists.llvm.org/pipermail/lldb-dev/2018-January/013186.html). I should have a patch up Very Soon! If you would like I can CC you to it. Thanks, Erik On 2018-03-...

Hi all, We know that 'ItaniumDemangle' has been added into llvm lib to resolve demangling related issues. And if we dump mangled function name '_Z3duti' into 'char *llvm::itaniumDemangle(const char *mangled_name, char *buf, size_t *n, int *status)', we will get 'dut(int)'. So my question is: How can I just get the function name 'dut' without parameters,

Hi all, Recently I do some jobs based on llvm-link tool. I wonder why link '@llvm.global_ctors' into dest file, even it's not used in dest file? And how can I remove it? Thank you all in advance!
