- Function calls on the SH look like this:
-
- movl L1,r0
- ...
- jsr @r0
- ...
- L1:
- .long function
-
- The compiler and assembler will cooperate to create R_SH_USES
- relocs on the jsr instructions. The r_offset field of the
- R_SH_USES reloc is the PC relative offset to the instruction which
- loads the register (the r_offset field is computed as though it
- were a jump instruction, so the offset value is actually from four
- bytes past the instruction). The linker can use this reloc to
- determine just which function is being called, and thus decide
- whether it is possible to replace the jsr with a bsr.
-
- If multiple function calls are all based on a single register load
- (i.e., the same function is called multiple times), the compiler
- guarantees that each function call will have an R_SH_USES reloc.
- Therefore, if the linker is able to convert each R_SH_USES reloc
- which refers to that address, it can safely eliminate the register
- load.
-
- When the assembler creates an R_SH_USES reloc, it examines it to
- determine which address is being loaded (L1 in the above example).
- It then counts the number of references to that address, and
- creates an R_SH_COUNT reloc at that address. The r_offset field of
- the R_SH_COUNT reloc will be the number of references. If the
- linker is able to eliminate a register load, it can use the
- R_SH_COUNT reloc to see whether it can also eliminate the function
- address.
-
- SH relaxing also handles another, unrelated, matter. On the SH, if
- a load or store instruction is not aligned on a four byte boundary,
- the memory cycle interferes with the 32 bit instruction fetch,
- causing a one cycle bubble in the pipeline. Therefore, we try to
- align load and store instructions on four byte boundaries if we
- can, by swapping them with one of the adjacent instructions. */

-@section Error reporting
-Most BFD functions return nonzero on success (check their
-individual documentation for precise semantics). On an error,
-they call @code{bfd_set_error} to set an error condition that callers
-can check by calling @code{bfd_get_error}.
-If that returns @code{bfd_error_system_call}, then check
-@code{errno}.
-
-The easiest way to report a BFD error to the user is to
-use @code{bfd_perror}.
-@*
-@subsection Type @code{bfd_error_type}
-The values returned by @code{bfd_get_error} are defined by the
-enumerated type @code{bfd_error_type}.
-@*

-the last BFD error was a system call failure. If @var{message}
-is non-NULL and non-empty, the error string printed is preceded
-by @var{message}, a colon, and a space. It is followed by a newline.
-@*
-@subsection BFD error handler
-Some BFD functions want to print messages describing the
-problem. They call a BFD error handler function. This
-function may be overriden by the program.
-
-The BFD error handler acts like printf.
-@*

-@example

-@example
-void bfd_set_error_program_name (const char *);
-@end example
-@strong{Description}@*
-Set the program name to use when printing a BFD error. This
-is printed before the error message followed by a colon and
-space. The string must not be changed after it is passed to
-this function.

-@strong{Description}@*
-Call the back end associated with the open BFD
-@var{abfd} and translate the external form of the relocation
-information attached to @var{sec} into the internal canonical
-form. Place the table into memory at @var{loc}, which has
-been preallocated, usually by a call to
-@code{bfd_get_reloc_upper_bound}. Returns the number of relocs, or
--1 on error.

-Set the flag word in the BFD @var{abfd} to the value @var{flags}.
-
-Possible errors are:
-@itemize @bullet
-
-@item
-@code{bfd_error_wrong_format} - The target bfd was not of object format.
-@item
-@code{bfd_error_invalid_operation} - The target bfd was open for reading.
-@item
-@code{bfd_error_invalid_operation} -
-The flag word contained a bit which was not applicable to the
-type of file. E.g., an attempt was made to set the @code{D_PAGED} bit
-on a BFD format which does not support demand paging.

-@subsubsection @code{bfd_set_start_address}
-@strong{Synopsis}
-@example
-boolean bfd_set_start_address(bfd *abfd, bfd_vma vma);

-@strong{Description}@*
-Make @var{vma} the entry point of output BFD @var{abfd}.

-@findex bfd_get_mtime
-@subsubsection @code{bfd_get_mtime}
-@strong{Synopsis}
-@example
-long bfd_get_mtime(bfd *abfd);
-@end example
-@strong{Description}@*
-Return the file modification time (as read from the file system, or
-from the archive header for archive members).
-@*
-@findex bfd_get_size
-@subsubsection @code{bfd_get_size}
-@strong{Synopsis}
-@example
-long bfd_get_size(bfd *abfd);
-@end example
-@strong{Description}@*
-Return the file size (as read from file system) for the file
-associated with BFD @var{abfd}.
-
-The initial motivation for, and use of, this routine is not
-so we can get the exact size of the object the BFD applies to, since
-that might not be generally possible (archive members for example).
-It would be ideal if someone could eventually modify
-it so that such results were guaranteed.
-
-Instead, we want to ask questions like "is this NNN byte sized
-object I'm about to try read from file offset YYY reasonable?"
-As as example of where we might do this, some object formats
-use string tables for which the first @code{sizeof(long)} bytes of the
-table contain the size of the table itself, including the size bytes.
-If an application tries to read what it thinks is one of these
-string tables, without some way to validate the size, and for
-some reason the size is wrong (byte swapping error, wrong location
-for the string table, etc.), the only clue is likely to be a read
-error when it tries to read the table, or a "virtual memory
-exhausted" error when it tries to allocate 15 bazillon bytes
-of space for the 15 bazillon byte table it is about to read.
-This function at least allows us to answer the quesion, "is the
-size reasonable?".

-Convert, like @code{strtoul}, a numerical expression

-(Though without as many bells and whistles as @code{strtoul}.)
-The expression is assumed to be unsigned (i.e., positive).
-If given a @var{base}, it is used as the base for conversion.

-
- When producing a relocateable object file, R_MIPS16_26 is
- handled mostly like R_MIPS_26. In particular, the addend is
- stored as a straight 26-bit value in a 32-bit instruction.
- (gas makes life simpler for itself by never adjusting a
- R_MIPS16_26 reloc to be against a section, so the addend is
- always zero). However, the 32 bit instruction is stored as 2
- 16-bit values, rather than a single 32-bit value. In a
- big-endian file, the result is the same; in a little-endian
- file, the two 16-bit halves of the 32 bit value are swapped.
- This is so that a disassembler can recognize the jal
- instruction.
-
- When doing a final link, R_MIPS16_26 is treated as a 32 bit
- instruction stored as two 16-bit values. The addend A is the
- contents of the targ26 field. The calculation is the same as
- R_MIPS_26. When storing the calculated value, reorder the
- immediate value as shown above, and don't forget to store the
- value as two 16-bit values.
-
- To put it in MIPS ABI terms, the relocation field is T-targ26-16,
- defined as
-
- big-endian:
- +--------+----------------------+
- | | |
- | | targ26-16 |
- |31 26|25 0|
- +--------+----------------------+
-
- little-endian:
- +----------+------+-------------+
- | | | |
- | sub1 | | sub2 |
- |0 9|10 15|16 31|
- +----------+--------------------+
- where targ26-16 is sub1 followed by sub2 (i.e., the addend field A is
- ((sub1 << 16) | sub2)).
-
- When producing a relocateable object file, the calculation is
- (((A < 2) | (P & 0xf0000000) + S) >> 2)
- When producing a fully linked file, the calculation is
- let R = (((A < 2) | (P & 0xf0000000) + S) >> 2)
- ((R & 0x1f0000) << 5) | ((R & 0x3e00000) >> 5) | (R & 0xffff) */

- +--------------+--------------------------------+
- ! Major ! rx ! ry ! Imm 4:0 !
- +--------------+--------------------------------+
-
- EXTEND is the five bit value 11110. Major is the instruction

-
