With the patch, the MC-generated code works fine in combination with a recent GNU as (2.23.51.20120920 here). Patch by David Nadlinger!

This value is truncated or zero-extended as the false boolean value to be returned. Boolean simplification needs to skip this 'zext' or 'trunc' node. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178312 91177308-0d34-0410-b5e6-96231b3b80d8 Skip moving call address loading into callseq when targets prefer register indirect call. 2013-03-28T23:13:21Z Michael Liao michael.liao@intel.com 2013-03-28T23:13:21Z urn:sha1:816f6d0ac76c0ffb2ea9ecb72349d5d7d0fa8d1a To enable a load of a call address to be folded with that call, this load is moved from outside of callseq into callseq. Such a moving adds a non-glued node (that load) into a glued sequence. This non-glue load is only removed when DAG selection folds them into a memory form call instruction. When such instruction selection is disabled, it breaks DAG schedule. To prevent that, such moving is disabled when target favors register indirect call. Previous workaround disabling CALL32m/CALL64m insn selection is removed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178308 91177308-0d34-0410-b5e6-96231b3b80d8 Add the X86 FMAs to the scheduling model. 2013-03-28T22:54:45Z Nadav Rotem nrotem@apple.com 2013-03-28T22:54:45Z urn:sha1:bad24f757d430ed9ef5348da58aa20d03409d6a0 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178303 91177308-0d34-0410-b5e6-96231b3b80d8 Add the Haswell machine model. 2013-03-28T22:34:46Z Nadav Rotem nrotem@apple.com 2013-03-28T22:34:46Z urn:sha1:59af9d0bf4601276d03c52cc22865bbeba03e375 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178301 91177308-0d34-0410-b5e6-96231b3b80d8 Remove the unused port from the SandyBridge machine model 2013-03-28T22:32:41Z Nadav Rotem nrotem@apple.com 2013-03-28T22:32:41Z urn:sha1:0b6a69d4a191b40923deceffc0bfff94be851569 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178300 91177308-0d34-0410-b5e6-96231b3b80d8
