The;; different patterns are only used to choose the right syntax.;;;; The svr4 m68k assembler recognizes this syntax: `bsr FUNC@PLTPC' and it;; will create the correct relocation entry (R_68K_PLT32) for `FUNC',;; that tells the linker editor to create an entry for `FUNC' in PLT;; section at link time. However, all global objects reference are still;; done by using `OBJ@GOT'. So, the goal here is to output the function;; call operand as `FUNC@PLTPC', but output object operand as `OBJ@GOT'.;; We need to have a way to differentiate these two different operands.;;;; The strategy I use here is to use SYMBOL_REF_FLAG to differentiate;; these two different operands. The macro LEGITIMATE_PIC_OPERAND_P needs;; to be changed to recognize function calls symbol_ref operand as a valid;; PIC operand (by checking whether SYMBOL_REF_FLAG is set). This will;; avoid the compiler to load this symbol_ref operand into a register.;; Remember, the operand "foo@PLTPC" cannot be called via jsr directly;; since the value is a PC relative offset, not a real address.;;;; All global objects are treated in the similar way as in SUN3. The only;; difference is: on m68k svr4, the reference of such global object needs;; to end with a suffix "@GOT" so the assembler and linker know to create;; an entry for it in GOT (Global Offset Table) section.
