Allocate the correct number of global registers
Fix fault formating and code for traps fix a couple of bugs in the decoder Cleanup/fix page table entry code Implement more mmaped iprs, fix numbered tlb insertion code, add function to dump tlb contents Don't panic if we differ from legion on a tcc instruction because of where legion prints its data and where we print our data src/arch/sparc/faults.cc: Fix fault formating and code for traps src/arch/sparc/intregfile.hh: allocate the correct number of global registers src/arch/sparc/isa/decoder.isa: fix a couple of bugs in the decoder: wrasi should write asi not ccr, done/retry should get hpstate from htstate src/arch/sparc/pagetable.hh: cleanup/fix page table code src/arch/sparc/tlb.cc: implement more mmaped iprs, fix numbered insertion code, add function to dump tlb contents src/arch/sparc/tlb.hh: add functions to write TagAccess register on tlb miss and to dump all tlb entries for debugging src/cpu/exetrace.cc: dump tlb entries on error, don't consider differences the cycle we take a trap to be bad. --HG-- extra : convert_revision : d7d771900f6f25219f3dc6a6e51986d342a32e03
