Hi: I am working on gcc-4.3.0 and Redhat ES 4. When I uses the compiler to build specint-2006 benchmarks, none passes the make with compiler option: -msched-control-spec (enable control speculation on IA-64) Here is part of the error log: # Error 400.perlbench: Error with make! # # Error 401.bzip2: Error with make! # # Error 403.gcc: Error with make! # # Error 429.mcf: Error with make! # # Error 445.gobmk: Error with make! # # Error 456.hmmer: Error with make! # # Error 458.sjeng: Error with make! # # Error 462.libquantum: Error with make! # # Error 464.h264ref: Error with make! # # Error 471.omnetpp: Error with make! # # Error 473.astar: Error with make! # # Error 483.xalancbmk: Error with make! # So any help ? Thanks
