1 2SparcV8 backend skeleton 3------------------------ 4 5This directory houses a 32-bit SPARC V8 backend employing an expander-based 6instruction selector. It is not yet functionally complete. Watch 7this space for more news coming soon! 8 9Current expected test failures 10------------------------------ 11 12Here are the currently-expected SingleSource failures for V8 13(Some C++ programs are crashing in libstdc++ at the moment; 14I'm not sure why.) 15 16 (llc) SingleSource/Regression/C++/EH/exception_spec_test 17 (llc) SingleSource/Regression/C++/EH/throw_rethrow_test 18 19Here are the currently-expected MultiSource failures for V8: 20 21 (llc,cbe) MultiSource/Applications/d/make_dparser 22 (llc,cbe) MultiSource/Applications/hexxagon 23 (llc) MultiSource/Benchmarks/Fhourstones 24 (llc,cbe) MultiSource/Benchmarks/McCat/03-testtrie 25 (llc) MultiSource/Benchmarks/McCat/18-imp 26 (llc,cbe) MultiSource/Benchmarks/Prolangs-C/bison/mybison 27 (llc,cbe) MultiSource/Benchmarks/Prolangs-C/fixoutput 28 (llc,cbe) MultiSource/Benchmarks/Prolangs-C/gnugo 29 (llc,cbe) MultiSource/Benchmarks/Prolangs-C/plot2fig 30 (llc,cbe) MultiSource/Benchmarks/Ptrdist/anagram 31 (llc,cbe) MultiSource/Benchmarks/FreeBench/analyzer 32 * DANGER * analyzer will run the machine out of VM 33 (I don't know whether the following fail in cbe:) 34 (llc) MultiSource/Benchmarks/FreeBench/distray 35 (llc) MultiSource/Benchmarks/FreeBench/fourinarow 36 (llc) MultiSource/Benchmarks/FreeBench/pifft 37 (llc) MultiSource/Benchmarks/MallocBench/gs 38 (llc) MultiSource/Benchmarks/Prolangs-C++/deriv1 39 (llc) MultiSource/Benchmarks/Prolangs-C++/deriv2 40 41Known SPEC failures for V8 (probably not an exhaustive list): 42 43 (llc) 134.perl 44 (llc) 177.mesa 45 (llc) 188.ammp -- FPMover bug? 46 (llc) 256.bzip2 47 (llc,cbe) 130.li 48 (native,llc,cbe) 126.gcc 49 (native,llc,cbe) 255.vortex 50 51To-do 52----- 53 54* support shl on longs (fourinarow needs this) 55* support casting 64-bit integers to FP types (fhourstones needs this) 56* support FP rem 57 58$Date$ 59 60
