7649 two patterns keeps CSE from performing this optimization).
7651 We now use even more call patterns as there was a subtle bug in
7652 attempting to restore the pic register after a call using a simple
7653 move insn. During reload, a instruction involving a pseudo register
7654 with no explicit dependence on the PIC register can be converted
7655 to an equivalent load from memory using the PIC register. If we
7656 emit a simple move to restore the PIC register in the initial rtl
7657 generation, then it can potentially be repositioned during scheduling.
7658 and an instruction that eventually uses the PIC register may end up
7659 between the call and the PIC register restore.
7661 This only worked because there is a post call group of instructions
7662 that are scheduled with the call. These instructions are included
7663 in the same basic block as the call. However, calls can throw in
7664 C++ code and a basic block has to terminate at the call if the call
7665 can throw. This results in the PIC register restore being scheduled
7666 independently from the call. So, we now hide the save and restore
7667 of the PIC register in the call pattern until after reload. Then,
7668 we split the moves out. A small side benefit is that we now don't
7669 need to have a use of the PIC register in the return pattern and
7670 the final save/restore operation is not needed.
7672 I elected to just clobber %r4 in the PIC patterns and use it instead
7673 of trying to force hppa_pic_save_rtx () to a callee saved register.
7674 This might have required a new register class and constraint. It
7675 was also simpler to just handle the restore from a register than a
7676 generic pseudo. */

7723 ;; The use of a function call hides the variable dependence of our calls
7724 ;; and millicode calls. The result is genattrtab doesn't treat the operation
7725 ;; as variable and it only generates code for the default case using our
7726 ;; function call. Because of this, calls and millicode calls have a fixed
7727 ;; length in the branch shortening pass, and some branches will use a longer
7728 ;; code sequence than necessary. However, the length of any given call

7732 ;; It's possible to trick genattrtab by adding an expression involving `pc'

7736 ;; calls to participate in branch shortening would be to make the call to
7737 ;; insn_default_length a target option. Then, we could massage unknown

8146 types of calls use different calling conventions, and CSE might try
8147 to change the named call into an indirect call in some cases (using
8148 two patterns keeps CSE from performing this optimization).
8150 We now use even more call patterns as there was a subtle bug in
8151 attempting to restore the pic register after a call using a simple
8152 move insn. During reload, a instruction involving a pseudo register
8153 with no explicit dependence on the PIC register can be converted
8154 to an equivalent load from memory using the PIC register. If we
8155 emit a simple move to restore the PIC register in the initial rtl
8156 generation, then it can potentially be repositioned during scheduling.
8157 and an instruction that eventually uses the PIC register may end up
8158 between the call and the PIC register restore.
8160 This only worked because there is a post call group of instructions
8161 that are scheduled with the call. These instructions are included
8162 in the same basic block as the call. However, calls can throw in
8163 C++ code and a basic block has to terminate at the call if the call
8164 can throw. This results in the PIC register restore being scheduled
8165 independently from the call. So, we now hide the save and restore
8166 of the PIC register in the call pattern until after reload. Then,
8167 we split the moves out. A small side benefit is that we now don't
8168 need to have a use of the PIC register in the return pattern and
8169 the final save/restore operation is not needed.
8171 I elected to just clobber %r4 in the PIC patterns and use it instead
8172 of trying to force hppa_pic_save_rtx () to a callee saved register.
8173 This might have required a new register class and constraint. It
8174 was also simpler to just handle the restore from a register than a
8175 generic pseudo. */
