Hello, I wrote a c++ file, and compile it by using riscv-g++ with -std=c++11 This program involves file stream. While running by gem5, the process will pause. I check insts with debug flags, finding that output paused at somewhere like this below:
34489000: system.cpu T0 : @_read : c_addi sp, sp, -16 : IntAlu : D=0x7ffffffffffffa30 34489500: system.cpu T0 : @_read+2 : c_sdsp ra, 8(sp) : MemWrite : D=0x0000000000077726 A=0x7ffffffffffffa38 34490000: system.cpu T0 : @_read+4 : c_sdsp s0, 0(sp) : MemWrite : D=0x00000000000b6000 A=0x7ffffffffffffa30 34490500: system.cpu T0 : @_read+6 : c_li a3, zero, 0 : IntAlu : D=0x0000000000000000 34491000: system.cpu T0 : @_read+8 : c_li a4, zero, 0 : IntAlu : D=0x0000000000000000 34491500: system.cpu T0 : @_read+10 : c_li a5, zero, 0 : IntAlu : D=0x0000000000000000 34492500: system.cpu T0 : @_read+12 : addi a7, zero, 63 : IntAlu : D=0x000000000000003f 34493500: system.cpu T0 : @_read+16 : ecall : No_OpClass : Type enter and it will run agian, but stop at the same instruction: ecall Have anyone ever met this situation? Could you tell me how to solve this problem? Thanks.
