2010-06-25The hasMemory argument is irrelevant to how the argumentDale Johannesen

2010-05-01rename InlineInfo.DevirtualizedCalls -> InlinedCalls toChris Lattner
reflect that it includes all inlined calls now, not just devirtualized ones. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102824 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-01Implement rdar://6295824 and PR6724 with two tiny changesChris Lattner
that can have a big effect :). The first is to enable the iterative SCC passmanager juice that kicks in when the scc passmgr detects that a function pass has devirtualized a call. In this case, it will rerun all the passes it manages on the SCC, up to the iteration count limit (4). This is useful because a function pass may devirualize a call, and we want the inliner to inline it, or pruneeh to infer stuff about it, etc. The second patch is to add *all* call sites to the DevirtualizedCalls list the inliner uses. This list is about to get renamed, but the jist of this is that the inliner now reconsiders *all* inlined call sites as candidates for further inlining. The intuition is this that in cases like this: f() { g(1); } g(int x) { h(x); } We analyze this bottom up, and may decide that it isn't profitable to inline H into G. Next step, we decide that it is profitable to inline G into F, and do so, which means that F now calls H. Even though the call from G -> H may not have been profitable to inline, the call from F -> H may be (in this case because a constant allows folding etc). In my spot checks, this doesn't have a big impact on code. For example, the LLC output for 252.eon grew from 0.02% (from 317252 to 317308) and 176.gcc actually shrunk by .3% (from 1525612 to 1520964 bytes). 252.eon never iterated in the SCC Passmgr, 176.gcc iterated at most 1 time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102823 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-26Fix a problem that lower invoke has with allocas (PR6694), and Chris Lattner
add a version of createLowerInvokePass that allows the client to specify whether it wants "expensive" or "cheap" lowering. Patch by Alex Mac! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102402 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-23switch InlineInfo.DevirtualizedCalls's list to be of WeakVH.Chris Lattner
This fixes a bug where calls inlined into an invoke would get changed into an invoke but the array would keep pointing to the (now dead) call. The improved inliner behavior is still disabled for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102196 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-22The inliner was choosing to not consider call sitesChris Lattner
that appear in the SCC as a result of inlining as candidates for inlining. Change this so that it *does* consider call sites that change from being indirect to being direct as a result of inlining. This allows it to completely "devirtualize" the testcase. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102146 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-22refactor the interface to InlineFunction so that most of the in/outChris Lattner
arguments are handled with a new InlineFunctionInfo class. This makes it easier to extend InlineFunction to return more info in the future. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102137 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-22when inlining something like this:Chris Lattner
define void @f3(void (i8*)* %__f) ssp { entry: call void %__f(i8* undef) unreachable } define void @f4(i8* %this) ssp align 2 { entry: call void @f3(void (i8*)* @f2) ssp ret void } The inliner is turning the indirect call to %__f into a direct call to F2. Make the call graph more precise when this happens. The inliner doesn't revisit call sites introduced by inlining, so there isn't an easy way to test for this, but a more precise callgraph is a good thing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102131 91177308-0d34-0410-b5e6-96231b3b80d8
