-information is propagated through the compiler and the code generator can

-Many unsupported features are now supported, and inline asm support in the X86

+<p>As a step towards making LLVM's integer types signless, several new
+instructions have been added to LLVM. The DIV instruction has become UDIV, SDIV,
+and FDIV. The REM instruction has become UREM, SREM and FREM. The SHR
+instruction has become ASHR and LSHR. See the <a href="LangRef.html">Language
