Yes, it sounds good. I can try tomorrow. Thank you for your advice !

I'm not very familiar with relocations but your fix looks the same as ARMTargetLowering::LowerCall, so from that perspective it lgtm (but I may be missing something).

The problem is that I want to pass only srsr which is an int. "marked" was just an example :) Thanks you!

Hello everyone, I have an integer and I want to convert it to StringRef in order to set metadata. setMetadata->(StringRef, MDNode*); It is there a native LLVM way to do it? 1. In the llvm::APSInt Class is toString() method, which seems it is not for this purpose 2. itoa and string are not part of LLVM 3. stringstream is not part of LLVM 4. to_string is not part of LLVM 5. any casting method?

...nt me to an example of how something like that is done? I’m used to working with the JIT machinery in memory but not writing object files out to disk. I’m have code to generate object files for AOT compilation - is it done the same way? Best, .Chris.

Hi, I found that http://llvm.org/doxygen seems to be out-of-date. The footer shows that the files are regenerated everyday. I guess that the input repository for doxygen has not been updated for a while. For example, http://llvm.org/doxygen/namespacellvm.html#adeb6bbe8b1bed333ee7608e1939153c0 It says llvm::ParseBitcodeFile() has following prototype: Module *ParseBitcodeFile(MemoryBuffer

Hi cschen, Here are the test scripts which I written when I was developing ARM exception handling support: https://github.com/loganchien/libcxx-scripts The script should work on Debian wheezy (cross-compiling from amd64 to armhf.) In general, here are the necessary steps: 1. Get a working arm-linux-gnueabihf gcc/g++ toolchain (for the headers and libraries) 2. Setup the include search path

Hi Anton, It seems that some release branches (e.g. release_30, release_35, and release_36) are missing from the Git mirror for libc++abi. May you help to fix the problem? Thanks.

Hi, I think you may try to use llvm::Twine(int). For example, to convert 30 to string, you can use: Twine(30).str() To convert the string back to integer, you can try the StringRef::getAsInteger(unsigned, APInt &). For example: APInt i; str.getAsInteger(/*radix=*/ 10, /*output=*/ i); Sincerely, Logan On Thu, May 2, 2013 at 9:53 PM, Alexandru Ionut Diaconescu <
