2010-06-29Introducing the "linker_weak" linkage type. This will be used for Objective-CBill Wendling
metadata types which should be marked as "weak", but which the linker will remove upon final linkage. For example, the "objc_msgSend_fixup_alloc" symbol is defined like this: .globl l_objc_msgSend_fixup_alloc .weak_definition l_objc_msgSend_fixup_alloc .section __DATA, __objc_msgrefs, coalesced .align 3 l_objc_msgSend_fixup_alloc: .quad _objc_msgSend_fixup .quad L_OBJC_METH_VAR_NAME_1 This is different from the "linker_private" linkage type, because it can't have the metadata defined with ".weak_definition". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107205 91177308-0d34-0410-b5e6-96231b3b80d8
2010-06-29Return Changed. This required setting Changed if dbg metadataDuncan Sands

2010-05-15Teach the always inliner to release its inline cost estimates, like the basicNick Lewycky
inliner did in r103653. Why does the always inliner even bother with cost estimates anyways? git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103858 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-13Replace the core comparison login in merge functions. We can now mergeNick Lewycky
vector<>::push_back() in: int foo(vector<int> &a, vector<unsigned> &b) { a.push_back(10); b.push_back(11); } to two calls to the same push_back function, or fold away the two copies of push_back() in: struct T { int; }; struct S { char; }; vector<T*> t; vector<S*> s; void f(T *x) { t.push_back(x); } void g(S *x) { s.push_back(x); } but leave f() and g() separate, since they refer to two different global variables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103698 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-12Clear CachedFunctionInfo upon Pass::releaseMemory. Because ValueMap will abortNick Lewycky
on RAUW of functions, this is a correctness issue instead of a mere memory usage problem. No testcase until the new MergeFunctions can land. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103653 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-01revert r102831. We already delete dead readonly calls inChris Lattner
other places, killing a valid transformation is not the right answer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102850 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-01Disable the call-deletion transformation introduced in r86975. WithoutOwen Anderson
halting analysis, it is illegal to delete a call to a read-only function. The correct solution is almost certainly to add a "must halt" attribute and only allow deletions in its presence. XFAIL the relevant testcase for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102831 91177308-0d34-0410-b5e6-96231b3b80d8
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
2010-05-01The inliner has traditionally not considered call sitesChris Lattner
that appear due to inlining a callee as candidates for futher inlining, but a recent patch made it do this if those call sites were indirect and became direct. Unfortunately, in bizarre cases (see testcase) doing this can cause us to infinitely inline mutually recursive functions into callers not in the cycle. Fix this by keeping track of the inline history from which callsite inline candidates got inlined from. This shouldn't affect any "real world" code, but is required for a follow on patch that is coming up next. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102822 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-23enable my inliner change: add newly devirtualized call sites toChris Lattner
the worklist, making them inline candidates. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102213 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
2010-04-23disable my previous inliner patch, it appears to be busting self-host.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102153 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

2010-04-20Fix rdar://7879828 - crash in CallGraph, a self host issue.Chris Lattner
Arg promotion was deleting call graph nodes that still had references from the 'indirect' CGN. Like the inliner, it should only delete the function if all references are gone. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101845 91177308-0d34-0410-b5e6-96231b3b80d8
