...your answer... I tried that without any luck: static void handleOBF(Sema &S, Decl *D, const AttributeList &Attr) { D->addAttr(::new (S.Context)NoFLAAttr(Attr.getRange(), S.Context, Attr.getAttributeSpellingListIndex())); // ??????????? llvm::AttrBuilder FuncAttrs; FuncAttrs.addAttribute(); } In CodeGenModule::ConstructAttributeList it uses a AttrBuilder, I tried there to add a random attribute and it works. But I’m not understanding how to do that in SemaDeclAttr.cpp. Cheers

...// 2". in "lib/AsmParser/LLParser.cpp" appears inaccurate, the "alignment" is later parsed as the alignment of the function itself, both when directly placed on the function: 02975 // If the alignment was parsed as an attribute, move to the alignment field. 02976 if (FuncAttrs.hasAlignmentAttr()) { 02977 Alignment = FuncAttrs.getAlignment(); 02978 FuncAttrs.removeAttribute(Attribute::Alignment); 02979 } and through an attribute group: 00088 // If the alignment was parsed as an attribute, move to the alignment 00089 // field. 00090 if (FnAttr...

Thanks for the suggestions Hal, So if I understand correctly, you're recommending we add a module flag <https://llvm.org/docs/LangRef.html#module-flags-metadata> to LLVM, something like: !llvm.module.flags = !{..., !123} !123 = !{i32 1, !"memeq_lib_function", !"user_memeq"} I've given it a try in the following patch: https://reviews.llvm.org/D56311 If this

Hi, I want to *tag* some functions with some *flags*. I was using annotate((“myFlag”)) and everything was working fine until I tried on ObjC method. It seems that clang just ignore it. So, to be able to *flag* my functions I’m trying to add a *real* attribute to clang. I’ve added a new attribute to clang in tools/clang/include/clang/Basic/Attr.td: def NoFLA : Attr { let Spellings =

I've been investigating what is needed to ensure command line options are passed to the backend codegen passes during LTO and enable compiling different functions in a module with different command line options (see the links below for previous discussions). http://thread.gmane.org/gmane.comp.compilers.llvm.devel/78855 http://thread.gmane.org/gmane.comp.compilers.llvm.devel/80456 The command
