;;- The '040 also implements a set of new floating-point instructions

;;- By default, GCC does not use these instructions, since such code will

-;; For PIC calls, in order to be able to support
-;; dynamic linker LAZY BINDING, all the procedure calls need to go
-;; through the PLT (Procedure Linkage Table) section in PIC mode.
-;;
-;; PIC calls are handled by loading the address of the function into a
-;; register (via movsi), then emitting a register indirect call using
-;; the "jsr" function call syntax.
-;;
-;; When outputting MIT syntax (e.g. on Suns), we add a bogus extra
-;; operand to the jbsr statement to indicate that this call should
-;; go through the PLT (why? because this is the way that Sun does it).
-;;
-;; We have different patterns for PIC calls and non-PIC calls. 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. This is done in
-;; m68k.c.
