Correct issues with INSN2_ALIAS annotation for branch instructions: - regular MIPS BEQZ/L and BNEZ/L assembly instructions are idioms for BEQ/L and BNE/L respectively with the `rs' operand equal to $0, - microMIPS 32-bit BEQZ and BNEZ assembly instructions are idioms for BEQ and BNE respectively with the `rt' operand equal to $0, - regular MIPS BAL assembly instruction is an idiom for architecture levels of up to the MIPSr5 ISA and a machine instruction on its own from the MIPSr6 ISA up. Add missing annotation to BEQZ/L and BNEZ/L accordingly then and add a new entry for BAL for the MIPSr6 ISA, correcting a disassembly bug: $ mips-linux-gnu-objdump -m mips:isa64r6 -M no-aliases -d bal.o bal.o: file format elf32-tradlittlemips Disassembly of section .text: 00000000 <foo>: 0: 04110000 0x4110000 ... $ Add test cases accordingly. Parts for regular MIPS BEQZ/L and BNEZ/L instructions from Sagar Patel. 2022-03-06 Maciej W.
