25 | ;; ??? Add support for long double XFmode patterns. | |
26 | ||
27 | ;; ??? register_operand accepts (subreg:DI (mem:SI X)) which forces later | |
28 | ;; reload. This will be fixed once scheduling support is turned on. | |
29 | ||
30 | ;; ??? Optimize for post-increment addressing modes. | |
31 | ||
32 | ;; ??? fselect is not supported, because there is no integer register | |
33 | ;; equivalent. | |
34 | ||
35 | ;; ??? fp abs/min/max instructions may also work for integer values. | |
36 | ||
37 | ;; ??? Would a predicate_reg_operand predicate be useful? The HP one is buggy, | |
38 | ;; it assumes the operand is a register and takes REGNO of it without checking. | |

43 | ;; ??? Go through list of documented named patterns and look for more to | |

120 | ;; Each usage of a function units by a class of insns is specified with a | |

122 | ;; (define_function_unit NAME MULTIPLICITY SIMULTANEITY TEST READY-DELAY | |
123 | ;; ISSUE-DELAY [CONFLICT-LIST]) | |
124 | ||
125 | ;; This default scheduling info seeks to pack instructions into bundles | |
126 | ;; efficiently to reduce code size, so we just list how many of each | |
127 | ;; instruction type can go in a bundle. ISSUE_RATE is set to 3. | |
128 | ||
129 | ;; ??? Add scheduler ready-list hook (MD_SCHED_REORDER) that orders | |
130 | ;; instructions, so that the next instruction can fill the next bundle slot. | |
131 | ;; This really needs to know where the stop bits are though. | |
132 | ||
133 | ;; ??? Use MD_SCHED_REORDER to put alloc first instead of using an unspec | |
134 | ;; volatile. Use ADJUST_PRIORITY to set the priority of alloc very high to | |
135 | ;; make it schedule first. | |
136 | ||
137 | ;; ??? Modify the md_reorg code that emits stop bits so that instead of putting | |
138 | ;; them in the last possible place, we put them in places where bundles allow | |
139 | ;; them. This should reduce code size, but may decrease performance if we end | |
140 | ;; up with more stop bits than the minimum we need. | |
