-/* This pass does simple forward propagation and simplification when an
- operand of an insn can only come from a single def. This pass uses
- RTL SSA, so it is global. However, we only do limited analysis of
- available expressions.
-
- 1) The pass tries to propagate the source of the def into the use,
- and checks if the result is independent of the substituted value.
- For example, the high word of a (zero_extend:DI (reg:SI M)) is always
- zero, independent of the source register.
-
- In particular, we propagate constants into the use site. Sometimes
- RTL expansion did not put the constant in the same insn on purpose,
- to satisfy a predicate, and the result will fail to be recognized;
- but this happens rarely and in this case we can still create a
- REG_EQUAL note. For multi-word operations, this
-
- (set (subreg:SI (reg:DI 120) 0) (const_int 0))
- (set (subreg:SI (reg:DI 120) 4) (const_int -1))
- (set (subreg:SI (reg:DI 122) 0)
- (ior:SI (subreg:SI (reg:DI 119) 0) (subreg:SI (reg:DI 120) 0)))
- (set (subreg:SI (reg:DI 122) 4)
- (ior:SI (subreg:SI (reg:DI 119) 4) (subreg:SI (reg:DI 120) 4)))
-
- can be simplified to the much simpler
-
- (set (subreg:SI (reg:DI 122) 0) (subreg:SI (reg:DI 119)))
- (set (subreg:SI (reg:DI 122) 4) (const_int -1))
-
- This particular propagation is also effective at putting together
- complex addressing modes. We are more aggressive inside MEMs, in
- that all definitions are propagated if the use is in a MEM; if the
- result is a valid memory address we check address_cost to decide
- whether the substitution is worthwhile.
-
- 2) The pass propagates register copies. This is not as effective as
- the copy propagation done by CSE's canon_reg, which works by walking
- the instruction chain, it can help the other transformations.
-
- We should consider removing this optimization, and instead reorder the
- RTL passes, because GCSE does this transformation too. With some luck,
- the CSE pass at the end of rest_of_handle_gcse could also go away.
-
- 3) The pass looks for paradoxical subregs that are actually unnecessary.
- Things like this:
-
- (set (reg:QI 120) (subreg:QI (reg:SI 118) 0))
- (set (reg:QI 121) (subreg:QI (reg:SI 119) 0))
- (set (reg:SI 122) (plus:SI (subreg:SI (reg:QI 120) 0)
- (subreg:SI (reg:QI 121) 0)))
-
- are very common on machines that can only do word-sized operations.
- For each use of a paradoxical subreg (subreg:WIDER (reg:NARROW N) 0),
- if it has a single def and it is (subreg:NARROW (reg:WIDE M) 0),
- we can replace the paradoxical subreg with simply (reg:WIDE M). The
- above will simplify this to
-
- (set (reg:QI 120) (subreg:QI (reg:SI 118) 0))
- (set (reg:QI 121) (subreg:QI (reg:SI 119) 0))
- (set (reg:SI 122) (plus:SI (reg:SI 118) (reg:SI 119)))
-
- where the first two insns are now dead. */
