  /* Use two different patterns for calls to explicitly named functions
     and calls through function pointers.  This is necessary as these two
     types of calls use different calling conventions, and CSE might try
     to change the named call into an indirect call in some cases (using
     two patterns keeps CSE from performing this optimization).
     
     We now use even more call patterns as there was a subtle bug in
     attempting to restore the pic register after a call using a simple
     move insn.  During reload, a instruction involving a pseudo register
     with no explicit dependence on the PIC register can be converted
     to an equivalent load from memory using the PIC register.  If we
     emit a simple move to restore the PIC register in the initial rtl
     generation, then it can potentially be repositioned during scheduling.
     and an instruction that eventually uses the PIC register may end up
     between the call and the PIC register restore.
     
     This only worked because there is a post call group of instructions
     that are scheduled with the call.  These instructions are included
     in the same basic block as the call.  However, calls can throw in
     C++ code and a basic block has to terminate at the call if the call
     can throw.  This results in the PIC register restore being scheduled
     independently from the call.  So, we now hide the save and restore
     of the PIC register in the call pattern until after reload.  Then,
     we split the moves out.  A small side benefit is that we now don't
     need to have a use of the PIC register in the return pattern and
     the final save/restore operation is not needed.
     
     I elected to just clobber %r4 in the PIC patterns and use it instead
     of trying to force hppa_pic_save_rtx () to a callee saved register.
     This might have required a new register class and constraint.  It
     was also simpler to just handle the restore from a register than a
     generic pseudo.  */

;; We use function calls to set the attribute length of calls and millicode
;; calls.  This is necessary because of the large variety of call sequences.
;; Implementing the calculation in rtl is difficult as well as ugly.  As
;; we need the same calculation in several places, maintenance becomes a
;; nightmare.
;;
;; However, this has a subtle impact on branch shortening.  When the
;; expression used to set the length attribute of an instruction depends
;; on a relative address (e.g., pc or a branch address), genattrtab
;; notes that the insn's length is variable, and attempts to determine a
;; worst-case default length and code to compute an insn's current length.

;; The use of a function call hides the variable dependence of our calls
;; and millicode calls.  The result is genattrtab doesn't treat the operation
;; as variable and it only generates code for the default case using our
;; function call.  Because of this, calls and millicode calls have a fixed
;; length in the branch shortening pass, and some branches will use a longer
;; code sequence than necessary.  However, the length of any given call
;; will still reflect its final code location and it may be shorter than
;; the initial length estimate.

;; It's possible to trick genattrtab by adding an expression involving `pc'
;; in the set.  However, when genattrtab hits a function call in its attempt
;; to compute the default length, it marks the result as unknown and sets
;; the default result to MAX_INT ;-(  One possible fix that would allow
;; calls to participate in branch shortening would be to make the call to
;; insn_default_length a target option.  Then, we could massage unknown
;; results.  Another fix might be to change genattrtab so that it just does
;; the call in the variable case as it already does for the fixed case.

  /* Use two different patterns for calls to explicitly named functions
     and calls through function pointers.  This is necessary as these two
     types of calls use different calling conventions, and CSE might try
     to change the named call into an indirect call in some cases (using
     two patterns keeps CSE from performing this optimization).

     We now use even more call patterns as there was a subtle bug in
     attempting to restore the pic register after a call using a simple
     move insn.  During reload, a instruction involving a pseudo register
     with no explicit dependence on the PIC register can be converted
     to an equivalent load from memory using the PIC register.  If we
     emit a simple move to restore the PIC register in the initial rtl
     generation, then it can potentially be repositioned during scheduling.
     and an instruction that eventually uses the PIC register may end up
     between the call and the PIC register restore.
     
     This only worked because there is a post call group of instructions
     that are scheduled with the call.  These instructions are included
     in the same basic block as the call.  However, calls can throw in
     C++ code and a basic block has to terminate at the call if the call
     can throw.  This results in the PIC register restore being scheduled
     independently from the call.  So, we now hide the save and restore
     of the PIC register in the call pattern until after reload.  Then,
     we split the moves out.  A small side benefit is that we now don't
     need to have a use of the PIC register in the return pattern and
     the final save/restore operation is not needed.
     
     I elected to just clobber %r4 in the PIC patterns and use it instead
     of trying to force hppa_pic_save_rtx () to a callee saved register.
     This might have required a new register class and constraint.  It
     was also simpler to just handle the restore from a register than a
     generic pseudo.  */
