Hi, I encountered an issue with inline assembly in my c files compiled with llvmc. When I have a push instruction in the inline assembly like: __asm__ volatile ( "push {r4}\n\t" ); the compiler will drop the curly braces and leave it in the generated assembly file as: push r4 And this is non-conformant with the ARM

Moshe, You're more than likely going to get a better response from https://devforums.apple.com/community/tools/xcode llvmdev is a mailing list for the LLVM project which is separate from Xcode development.

Hi Moshe, Tim just did tell you what to do :) "Reporting it at llvm.org/bugs (and/or bugreporter.apple.com since that seems to be your platform) would make sure it doesn't get lost." So filing a bug report would be best. -eric On Wed, Jun 12, 2013 at 12:18 PM, Moshe Kravchik <mkravchik at hotmail.com> wrote: > So probably it is a LLVM issue - can anyone from the team look at it and let > me know if there is anything to do. > > Moshe > >> Date: Wed, 12 Jun 2013 10:53:56 -0700 >> Subject: Re: [LLVMdev] Apple clang 4.2 based on llvm 3.2 pr...

Hi, I've got an assembly file which used to compile with previous clang versions. However with 4.2 I get the following error: admin$ /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang -arch armv7 ./src/asm.s -o asm.o ./src/asm.s:30:5: error: instruction requires a CPU feature not currently enabled add r2, pc, r2 According to ARM

Hi, I'm looking for a pragma to insert in my source that will turn the optimization off for that file. Could not find one, it is possible?

Hi, I have encountered an issue which seems to be a serious reproducible bug in LLVM-GCC 4.2. It can be reproduced by compiling the following C++ file that uses boost:#include "boost/statechart/event.hpp" using namespace std; class EvActivate : public boost::statechart::event< EvActivate > { public: EvActivate(){} private: }; extern "C" const void*
