a variable. The previous code would break the debug info changing code invariant. This will regress debug info for arguments where we elide the alloca created. Fixes rdar://11066468 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153074 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-19Fix two bugpoint bugs:Chris Lattner
1) opt is not usually in the same path as the target program. Even for the bugpoint as a standalone app, it should be more portable to search in PATH, isn't it? 2) bugpoint driver accounts opt plugins, but does not list them in the final output command.

fast-isel before emitting code.

2012-03-16Rip out support for 'llvm.noinline'. This thing has a strange history...Chandler Carruth
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152904 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-16Start removing the use of an ad-hoc 'never inline' set and insteadChandler Carruth
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152903 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-16Pull the implementation of the code metrics out of the inline costChandler Carruth
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152898 91177308-0d34-0410-b5e6-96231b3b80d8
