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 Add boolean simplification support from CMOV 2012-09-10T16:36:16Z Michael Liao michael.liao@intel.com 2012-09-10T16:36:16Z urn:sha1:7fdc66bf73150a33c4e7558be89126a30a63f3b6 - If a boolean value is generated from CMOV and tested as boolean value, simplify the use of test result by referencing the original condition. RDRAND intrinisc is one of such cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163516 91177308-0d34-0410-b5e6-96231b3b80d8 add X86-specific DAG optimization to simplify boolean test 2012-08-10T19:58:13Z Michael Liao michael.liao@intel.com 2012-08-10T19:58:13Z urn:sha1:2a33cec66a5d1b755e2bb045bdac1690fdcff19e - if a boolean test (X86ISD::CMP or X86ISD:SUB) checks a boolean value generated from X86ISD::SETCC, try to simplify the boolean value generation and checking by reusing the original EFLAGS with proper condition code - add hooks to X86 specific SETCC/BRCOND/CMOV, the major 3 places consuming EFLAGS part of patches fixing PR12312 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161687 91177308-0d34-0410-b5e6-96231b3b80d8
