This book describes the operations of the Solaris Operating System (Solaris OS) link-editor and runtime linker, and the objects on which these link-editors operate. The book covers the Link-Editor: ld(1), the Runtime Linker: ld.so.1(1), Shared Objects (s

In both examples, it can be seen that PIC on x64 requires less instructions than on x86. On x86, the GOT address is loaded into some base register (ebx by convention) in two steps – first the address of the instruction is obtained with a special function call, and then the offset to...
Key insight #2 – making an IP-relative offset work on x86 The above is only useful if we can actually put the relative offset to work. But data references (i.e. in the mov instruction) on x86 require absolute addresses. So, what can we do?
I'm also working on the CAN bootloader and using AN12323 as a base code for that. i want to make my application position independent for that I want to implement PIC. i was reading this space for some support, can you either share the code or guide me through it to achie...
aThe -fPIC flag directs the compiler to generate position independent code (more on this in the next section). The -shared flag directs the linker to create a shared object file. - fPIC旗子在此指挥编译器更引起 (位置独立代码在下个部分)。 -共有的旗子指挥连接器创造一份共有的目标文件。 [...
using "-fPIC" (position independent code) is the use in shared dynamic libraries. This makes the overall footprint of all dynamically linked ELF executables on the system as small as possible, while it also prevents possible code duplication and actively reduces requirements on memory and file ...
The address of a call sequence instruction using the memory offset pointer value is determined based on the register 66 and the value stored in the memory offset pointer. When an image file 28 is loaded to the memory 14, the address of a procedure 24 is sent to the register 66, and ...
So PIC on x64 still requires extra instructions when compared to non-PIC code, but the additional cost is smaller. The indirect cost of tying down a register to use as the GOT pointer (which is painful on x86) is also gone, since no such register is needed with RIP-relative addressing...
