- ;; * Try using define_insn instead of some peepholes in more places.
- ;; * Set REG_NOTES:REG_EQUIV for cvt[bh]w loads. This would make the
- ;; backward scan in sign_extend needless.
- ;; * Match (pc) (label_ref) case in peephole patterns.
- ;; * Should optimize
- ;; "cmpX op1,op2; b{eq,ne} LY; ucmpX op1.op2; b{lt,le,gt,ge} LZ"
- ;; to
- ;; "ucmpX op1,op2; b{eq,ne} LY; b{lt,le,gt,ge} LZ"
- ;; by pre-scanning insn and running notice_update_cc for them.
- ;; * Is it necessary to do copy_rtx in the test and compare patterns?
- ;; * Fix true frame pointer omission.
- ;; * Make the jump tables contain branches, not addresses! This would
- ;; save us one instruction.
- ;; * Could the complicated scheme for compares be simplified, if we had
- ;; no named cmpqi or cmphi patterns, and instead anonymous patterns for
- ;; the less-than-word compare cases pyr can handle???
- ;; * The jump insn seems to accept more than just IR addressing. Would
- ;; we win by telling GCC? Or can we use movw into the global reg which
- ;; is a synonym for pc?
- ;; * More DImode patterns.
- ;; * Scan backwards in "zero_extendhisi2", "zero_extendqisi2" to find out
- ;; if the extension can be omitted.
- ;; * "divmodsi" with Pyramid "ediv" insn. Is it possible in rtl??
- ;; * Would "rcsp tmpreg; u?cmp[bh] op1_regdispl(tmpreg),op2" win in
- ;; comparison with the two extensions and single test generated now?
- ;; The rcsp insn could be expanded, and moved out of loops by the
- ;; optimizer, making 1 (64 bit) insn of 3 (32 bit) insns in loops.
- ;; The rcsp insn could be followed by an add insn, making non-displacement
- ;; IR addressing sufficient.

- ; The argument for the rather complicated test and compare expansion
- ; scheme, is the irregular pyramid instructions for these operations.
- ; 1) Pyramid has different signed and unsigned compares. 2) HImode
- ; and QImode integers are memory-memory and immediate-memory only. 3)
- ; Unsigned HImode compares doesn't exist. 4) Only certain
- ; combinations of addresses are allowed for memory-memory compares.
- ; Whenever necessary, in order to fulfill these addressing
- ; constraints, the compare operands are swapped.
