If the program bails after code was emitted, then it could lead to the stack being adjusted more than once (two CALLSEQ_BEGINs emitted) but being adjuste back only once after the call.

* Rip out support for 'llvm.noinline'. This thing has a strange history...Chandler Carruth2012-03-161-45/+0
| | | | | | | | | | | | | | | | | | | | | It was added in 2007 as the first cut at supporting no-inline attributes, but we didn't have function attributes of any form at the time. However, it was added without any mention in the LangRef or other documentation. Later on, in 2008, Devang added function notes for 'inline=never' and then turned them into proper function attributes. From that point onward, as far as I can tell, the world moved on, and no one has touched 'llvm.noinline' in any meaningful way since. It's time has now come. We have had better mechanisms for doing this for a long time, all the frontends I'm aware of use them, and this is just holding back progress. Given that it was never a documented feature of the IR, I've provided no auto-upgrade support. If people know of real, in-the-wild bitcode that relies on this, yell at me and I'll add it, but I *seriously* doubt anyone cares. llvm-svn: 152904
* Start removing the use of an ad-hoc 'never inline' set and insteadChandler Carruth2012-03-164-42/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | directly query the function information which this set was representing. This simplifies the interface of the inline cost analysis, and makes the always-inline pass significantly more efficient. Previously, always-inline would first make a single set of every function in the module *except* those marked with the always-inline attribute. It would then query this set at every call site to see if the function was a member of the set, and if so, refuse to inline it. This is quite wasteful. Instead, simply check the function attribute directly when looking at the callsite. The normal inliner also had similar redundancy. It added every function in the module with the noinline attribute to its set to ignore, even though inside the cost analysis function we *already tested* the noinline attribute and produced the same result. The only tricky part of removing this is that we have to be able to correctly remove only the functions inlined by the always-inline pass when finalizing, which requires a bit of a hack. Still, much less of a hack than the set of all non-always-inline functions was. While I was touching this function, I switched a heavy-weight set to a vector with sort+unique. The algorithm already had a two-phase insert and removal pattern, we were just needlessly paying the uniquing cost on every insert. This probably speeds up some compiles by a small amount (-O0 compiles with lots of always-inline, so potentially heavy libc++ users), but I've not tried to measure it. I believe there is no functional change here, but yell if you spot one. None are intended. Finally, the direction this is going in is to greatly simplify the inline cost query interface so that we can replace its implementation with a much more clever one. Along the way, all the APIs get simplified, so it seems incrementally good. llvm-svn: 152903
* Pull the implementation of the code metrics out of the inline costChandler Carruth2012-03-163-158/+177
| | | | | | | | | | | analysis implementation. The header was already separated. Also cleanup all the comments in the header to follow a nice modern doxygen form. There is still plenty of cruft here, but some of that will fall out in subsequent refactorings and this was an easy step in the right direction. No functionality changed here. llvm-svn: 152898
* misched: add DAG edges from vreg defs to ExitSU.Andrew Trick2012-03-161-1/+3
| | | | | | | | | | These edges are not really necessary, but it is consistent with the way we currently create physreg edges. Scheduler heuristics that expect a DAG edge to the block terminator could benefit from this change. Although in the future I hope we have a better mechanism for modeling latency across scheduling regions. llvm-svn: 152895
* LSR fix: Add isSimplifiedLoopNest to IVUsers analysis.Andrew Trick2012-03-164-17/+63
| | | | | | | | | | | | | | Only record IVUsers that are dominated by simplified loop headers. Otherwise SCEVExpander will crash while looking for a preheader. I previously tried to work around this in LSR itself, but that was insufficient. This way, LSR can continue to run if some uses are not in simple loops, as long as we don't attempt to analyze those users.
