| | | | | | | | | | | | datatypes on a given CPU. This is intended to allow instcombine and other transformations to avoid converting big sequences of operations to an inconvenient width, and will help clean up after SRoA. See also "Adding legal integer sizes to TargetData" on Feb 1, 2009 on llvmdev, and PR3451. Comments welcome. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@86370 91177308-0d34-0410-b5e6-96231b3b80d8

* Revert 85678/85680. The decision is to stay with the current form of Chris Lattner2009-11-011-4/+2
| | | | | | | | indirectbr, thus we don't need "blockaddr(@func, null)". Eliminate it for simplicity. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85699 91177308-0d34-0410-b5e6-96231b3b80d8
* Make blockaddress(@func, null) be valid, and make 'deleting a basic Chris Lattner2009-10-311-2/+4
| | | | | | | | | | | | | 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). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85678 91177308-0d34-0410-b5e6-96231b3b80d8
