* Revert 85678/85680. The decision is to stay with the current form of Chris Lattner2009-11-011-3/+5
| | | | | | | indirectbr, thus we don't need "blockaddr(@func, null)". Eliminate it for simplicity. llvm-svn: 85699
* Make blockaddress(@func, null) be valid, and make 'deleting a basic Chris Lattner2009-10-311-5/+3
| | | | | | | | | | | | block with a blockaddress still referring to it' replace the invalid blockaddress with a new blockaddress(@func, null) instead of a inttoptr(1). This changes the bitcode encoding format, and still needs codegen support (this should produce a non-zero value, referring to the entry block of the function would also be quite reasonable). llvm-svn: 85678
* if basic blocks are destroyed while there are *just* BlockAddress' hanging Chris Lattner2009-10-301-0/+18

* Introduce a new technique for merging BasicBlock with Instruction sentinel ↵Gabor Greif2009-02-271-34/+0
| | | | | | | | | by superposition. This looks dangerous, but isn't because the sentinel is accessed in special way only, namely the Next and Prev fields of it, and these are guaranteed to exist. llvm-svn: 65626

| | | | | | | | | | | | | | | | a new ilist_node class, and remove them. Unlike alist_node, ilist_node doesn't attempt to manage storage itself, so it avoids the associated problems, including being opaque in gdb. Adjust the Recycler class so that it doesn't depend on alist_node. Also, change it to use explicit Size and Align parameters, allowing it to work when the largest-sized node doesn't have the greatest alignment requirement. Change MachineInstr's MachineMemOperand list from a pool-backed alist to a std::list for now. llvm-svn: 54146

* Two things. Preserve the unwind_to when splitting a BB.Nick Lewycky2008-03-091-6/+13
| | | | | | | Add the ability to remove just one instance of a BB from a phi node. This fixes the compile error in the tree now. llvm-svn: 48085
* Add an unwind_to field to basic blocks, making them Users instead of Values.Nick Lewycky2008-03-021-2/+21

* The (negative) offset from a SymbolTableListTraits-using ilist to its containerChris Lattner2007-04-171-2/+0
| | | | | | | | | object is always constant. As such, evaluate it at compile time instead of storing it as an ivar in SymbolTableListTraits. This shrinks every SymbolTableListTraits ilist by a word, shrinking BasicBlock from 44->40 bytes, Function from 96->88 bytes, and Module from 60->52 bytes. llvm-svn: 36189
* Refactor SymbolTableListTraits to only have a single pointer in it, insteadChris Lattner2007-04-171-9/+19
| | | | | | | | of two. This shrinkifies Function by 8 bytes (104->96) and Module by 8 bytes (68->60). On a testcase of mine, this reduces the memory used to read a module header from 565680b to 561024, a little over 4K. llvm-svn: 36188
* Switch ValueSymbolTable to use StringMap<Value*> instead of ↵Chris Lattner2007-02-121-1/+3
| | | | | | | | | std::map<std::string, Value*> as its main datastructure. There are many improvements yet to be made, but this speeds up opt --std-compile-opts on 447.dealII by 7.3%. llvm-svn: 34193
