http://llvm.org/bugs/show_bug.cgi?id=14792 Problem: In the i386 ABI Page 3-10, it said that the stack is aligned. However, the two example code show that does not handle the alignment correctly when using variadic function. For example, if the size of the first argument is 17, the overflow_arg_area in va_list will be set to "address of first argument + 16" instead of "address of

Thx again Evan for the review. Here's a new patch for the JIT in itself. The major changes are: 1) A JITMemoryManager now has a flag saying "I require to know the size of what you want to emit" 2) DwarfJITEmitter is augmented with GetSize* functions 3) JITEmitter::startFunction checks if the JITMemoryManager requires to know the size. If so, it computes it and gives it through the
