This series of patches adds the target stubs, a basic testboard and a softmmu for system mode emulation. Furthermore it adds all the 16 bit long instructions of the architecture grouped by opcode format. After this series of patches. Another one will follow, which adds a lot of the 32 bit long instructions. All the best Bastian v4 -> v5: - Change documentation of S, SV bits to use bit 31. - psw_read/_write now uses only bit 31 of S, SV bits. - gen_intermediate_code_internal: Move calculation of next_pc after the ifs for singlestep and long tbs. - gen_shaci: Change case of shift_count == 32 to shift_count == -32 and add the clear of V bit. - gen_shaci: Move creation and freeing of t_max, t_min to case shift_count > 0. - gen_shaci: Add cast to int32_t to the creation of t_min. - gen_shaci: Now msk is 1 bit longer and uses a positive value of shift_count in the else case. - gen_shaci: now computes V bit in bit 31. - gen_shaci: Move computation of shift after the computation of PSW bits to handle the case of ret = r1. - gen_shaci: Add clear of V bit for cases shift_count = 0 / = -32 / < 0. - gen_add_d now saves result of addition into tcg temp to handle ret = r1 cases. - gen_cond_add now sets SV, SAV bits conditionally. - gen_cond_add now writes result after PSW bit computations, to handle ret = r1 cases. - Change int cond to TCGCond on function gen_cond_add, gen_condi_add. - Switched source and destination register of SRC_ADD_A15 and SRC_ADD_15A insns. - Negate conditions of 16_SRC_CMOV and 16_SRC_CMOVN insns. - SRC_MOV_A loads const4 zero extended. (Googled alot to find a manual saying it should be sign extended, but couldn't. 1.3 and 1.6 manual state sign extension) - RSUB now computes V bit in bit 31. - gen_sub_d now saves result of substraction into tcg temp to handle ret = r1 cases. - gen_mul_i32s now calculates V, SV bits in bit 31. - SSOV makro now computes V, SV bits in bit 31. - Negate conditions of 16_SRR_CMOV and 16_SRR_CMOVN insns. - MOV_AA: Switch r1 and r2 arguments. - decode_16Bit_opc: Add if to handle ADDSC.A opcode being 6 bit instead of 7 bit long. - Change int cond to TCGCond in functions gen_branch_cond, gen_branch_condi. - gen_intermediate_code_internal: Add gen_goto_tb so qemu finds new tb on singlestep and after long tbs without branch. - Switched sat_neg and arg in first movcond in function gen_saturate. - SR_NOT: Remove if checking OP2.
