It is at the end allowing for oddities like debug info and multiple branches. You might want to look at AnalyzeBranch.

Is there any way to tell where in the Instruction list, the branch to the other MachineBasicBlock happens? I know in the BasicBlock had a nice api for it.

...and emit it in ISel. But without -fast option ISD::DECLARE nodes are not created. How can i access the debug info for local variables in that case? Is it available directly somewhere in AsmPrinter like the debug info for global variables?

Hi, I ran Spec2006 with -O4. All integer benchmarks passed, but only 8 out 17 of floating point benchmarks passed. Is this normal or I made a mistake in my build?

Hi Folks, I'm having some difficulties getting LLVM to build and work correctly on CENTOS 5.3. This is basically tracked down easily enough to CENTOS using GCC 4.1.x by default, which is known-buggy and known not to work with LLVM -- I was getting the well-known problem with aborts due to a non-empty symbol table. I have installed the gcc43 package via yum (I'm trying to stick

Thanks. I could take a look at the lines and all of them have smull instruction like 'smull r0, r1, r0, r1'.

Works for me. Presumably #including <cassert> will fix it though?
