Display the contents of the symbol table(s)

objdump --syms -F elf_file > elf_file.symbol

objdump -h -S elf_file > elf_file.header

$(LD) $(CODE_LDFLAGS) -T $(CODE_LD_SCR) -Map $(CODE_LD_MAP) -o $@ $^ $(CODE_LIB_OPTS) $(GCC_LIB) $(CODE_DEC_LIB_OPTS) 
$(OD) -Mno-aliases,numeric -d $@ > $@.od
$(READELF) -a $@ > $@.elf.txt
$(OC) --only-section .text -O binary $@ $@.text.bin
$(OC) --only-section .data -O binary $@ $@.data.bin

 

ld  $(LDFLAG) -T ld_script -Map out_map -o out.exe LIBS
objcopy --only-section .data -O binary elf_file out.data.bin    ##输出文件可以用于.rodata初始化
objcopy --only-section .text -O binary elf_file out.text.bin
objdump -Mno-aliases,numeric -d elf_file > elf_file.od
readelf -a elf_file > elf_file.elf.txt
