-/* This file contains code for a pass to change spilled pseudos into
- memory.
-
- The pass creates necessary stack slots and assigns spilled pseudos
- to the stack slots in following way:
-
- for all spilled pseudos P most frequently used first do
- for all stack slots S do
- if P doesn't conflict with pseudos assigned to S then
- assign S to P and goto to the next pseudo process
- end
- end
- create new stack slot S and assign P to S
- end
-
- The actual algorithm is bit more complicated because of different
- pseudo sizes.
-
- After that the code changes spilled pseudos (except ones created
- from scratches) by corresponding stack slot memory in RTL.
-
- If at least one stack slot was created, we need to run more passes
- because we have new addresses which should be checked and because
- the old address displacements might change and address constraints
- (or insn memory constraints) might not be satisfied any more.
-
- For some targets, the pass can spill some pseudos into hard
- registers of different class (usually into vector registers)
- instead of spilling them into memory if it is possible and
- profitable. Spilling GENERAL_REGS pseudo into SSE registers for
- Intel Corei7 is an example of such optimization. And this is
- actually recommended by Intel optimization guide.
-
- The file also contains code for final change of pseudos on hard
- regs correspondingly assigned to them. */
