I'm rewriting this patch for the stubs to not use outputing of raw text. Generating the instructions is very straightforward and that part is done. I'm translating the actual function now. How do you emit an .ent or .globl from asm printer? .type ? .end ?? .section ??? I'm studying the classes now but it should be simple to do so if you know, you can save me some time because this

...I've had included a EmitCOFFSymbolDef in MCStreamer to replace the EmitRawText that was handling this, seem to me it would be easier to have a single call given the restrictions on their use. Sure, whatever you guys think is best. It is also very reasonable to add new enums to MCSymbolAttr if EmitSymbolAttribute is the right callback for these. -Chris -------------- next part -------------- An HTML attachment was scrubbed...

This is just a cosmetic change in MCAsmStreamer.cpp/EmitSymbolAttribute: all attributes have now a \t before and after, as done for '.type'. This makes the output look consistent, as well as help some third party assemblers expecting the attributes to be in the second column. The patch applies cleanly on the svn head.

...y AsmPrinter::EmitLinkage(), to decide if special stuff needs to be done. As I just want "weak", I should leave WeakDefDirective as null. Is this right? It would be nice if there was a additional hasWeakDefDirective that a target could specify (default false). Also should MCAsmStreamer::EmitSymbolAttribute() emitted MAI->getWeakDefDirective() rather than "\t.weak_definition\t"?

I have a problem where my LLVM-generated code works on Linux but not on OS X, and the problem involves non_lazy_ptr. I have an external symbol named "@gc_safepoint_map", which is generated by the linker's GCStrategy plugin. Since it is not generated until link time, I declared it as an external symbol so that the modules that use it can compile without error. Here's what the

Attached is an example of how to reproduce the issue. It uses a C file that happens to has a bunch of switch statements which are encoded as jump tables, giving us data-in-code. Usage: To build object files with clang via the -integrated-as versus via GCC: $ export NDK_DIR=<my_ndk_dir> $ export LLVM_DIR=<my_llvm_bin_dir> $ make To test that the generated objects contain the same

Firstly, do you need "main.dsp" defined as an external symbol, or can all external references go via "main"? If the answer is the latter, that will make the solution simpler. If only the latter, you will need to make a change to LLVM here: http://llvm-cs.pcc.me.uk/lib/CodeGen/AsmPrinter/AsmPrinter.cpp#650 Basically you would need to add a hook to the TargetLoweringObjectFile
