126to the machine and operating system on which it is built. However, minor

412 This document, which is not Itanium specific, specifies a standard for name
413 mangling, class layout, v-table layout, RTTI formats, and other C++
414 representation issues. Because we use this API, code generated by the LLVM
415 compilers should be binary compatible with machine code generated by other
416 Itanium ABI C++ compilers (such as G++, the Intel and HP compilers, etc).
417 <i>However</i>, the exception handling mechanism used by LLVM is very
418 different from the model used in the Itanium ABI, so <b>exceptions will not
