所以我第一次进入集会。我有一个演示程序,只是设置一些值,然后移动它们之间的内存位置和寄存器。
太简单了。
问题是,当我试图分析gdb
中的程序时,会得到以下错误:Reading symbols from DataTypes... (no debugging symbols found)... done
。
GDB被配置为i686-linux-gnu
并在一个Windows 10托管的VMWare实例中的Kali Linux上运行。uname -a: Linux Kali 4.17.0-kali1-686-pae #1 SMP Debian 4.17.8-1kali1 (2018-07-04) i686 GNU Linux
。
我的代码。。。
# Demo program to show how to use Data types and MOVx instructions
.data
HelloWorld:
.ascii "Hello World!"
ByteLocation:
.byte 10
Int32:
.int 2
Int16:
.short 3
Float:
.float 10.23
IntegerArray:
.int 10,20,30,40,50
.bss
.comm LargeBuffer, 10000
.text
.globl _start
_start:
nop
# 1. MOV immediate value into register
movl $10, %eax
# 2. MOV immediate value into memory location
movw $50, Int16
# 3. MOV data between registers
movl %eax, %ebx
# 4. MOV data from memory to register
movl Int32, %eax
# 5. MOV data from register to memory
movb $3, %al
movb %al, ByteLocation
# 6. MOV data into an indexed memory location
# Location is decided by BaseAddress(Offset, Index, DataSize)
# Offset and Index must be registers, Datasize can be a numerical value
movl $0, %ecx
movl $2, %edi
movl $22, IntegerArray(%ecx,%edi , 4)
# 7. Indirect addressing using registers
movl $Int32, %eax
movl (%eax), %ebx
movl $9, (%eax)
# Exit syscall to exit the program
movl $1, %eax
movl $0, %ebx
int $0x80
最佳答案
根据Jester的建议
我使用as
标志用-g
重新运行编译。as -g -o DataTypes.o DataTypes.s
链接的ld -o DataTypes DataTypes.o
运行GDBgdb ./DataTypes
关于linux - 汇编程序在GDB中找不到调试符号,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/52872261/
