Asmc Macro Assembler Reference
Position Independent Code (PIC)
Generate position-independent code for ELF.
These options (-fpic and -fPIC) instruct the assembler to generate position-independent code suitable for use in shared libraries. When either of these options is used, the assembler defines the corresponding preprocessor macros with the specified value.
The difference between -fpic and -fPIC is that -fPIC generates GOTX relocations for global data accesses. In contrast, -fpic generates GOT relocations. Additionally, the option -fno-plt can also be used in conjunction with -fpic or -fPIC to avoid using the Procedure Linkage Table (PLT) for function calls. Option -fplt enables the use of the PLT for function calls.
The -fno-pic option can be used to disable position-independent code generation. This is the default behavior for Asmc.
