2010-08-31Fix an infinite loop; merging two functions will create a new function (if theNick Lewycky
two are weak, we make them thunks to a new strong function) so don't iterate through the function list as we're modifying it. Also add back the outermost loop which got removed during the cleanups. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112595 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-31Switch to DenseSet, simplifying much more code. We now have a single iterationNick Lewycky
where we hash, compare and fold, instead of one iteration where we build up the hash buckets and a second one to fold. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112582 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-26Reapply r112091 and r111922, support for metadata linking, with aDan Gohman
fix: add a flag to MapValue and friends which indicates whether any module-level mappings are being made. In the common case of inlining, no module-level mappings are needed, so MapValue doesn't need to examine non-function-local metadata, which can be very expensive in the case of a large module with really deep metadata (e.g. a large C++ program compiled with -g). This flag is a little awkward; perhaps eventually it can be moved into the ClonedCodeInfo class. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112190 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-02Work in progress.Nick Lewycky
Start cleaning up MergeFunctions to look more like the rest of LLVM. The primary change here is to move the methods responsible for comparison into the new FunctionComparator object. Some comments added. There's more to do. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@110021 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-31The BlockExtractorPass() constructor was not reading the BlockFile and that wasRafael Espindola
exactly what bugpoint expected it to do. There was also only one user of BlockExtractorPass(const std::vector<BasicBlock*> &B), so just remove it and make BlockExtractorPass read BlockFile. This fixes bugpoint's block extraction. Nick, please review. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@109936 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-07Rename "Release" builds as "Release+Asserts"; rename "Release-Asserts"Duncan Sands
builds to "Release". The default build is unchanged (optimization on, assertions on), however it is now called Release+Asserts. The intent is that future LLVM releases released via llvm.org will be Release builds in the new sense, i.e. will have assertions disabled (currently they have assertions enabled, for a more than 20% slowdown). This will bring them in line with MacOS releases, which ship with assertions disabled. It also means that "Release" now means the same things in make and cmake builds: cmake already disables assertions for "Release" builds AFAICS. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107758 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-01Implement the "linker_private_weak" linkage type. This will be used forBill Wendling
Objective-C metadata types which should be marked as "weak", but which the linker will remove upon final linkage. However, this linkage isn't specific to Objective-C. 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". Currently only supported on Darwin platforms. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107433 91177308-0d34-0410-b5e6-96231b3b80d8
