Help with identifing all cost models in GCC to make it adaptable ?..

[David Edelsohn]

Grigori,

	Many of the costs now are handled by GCC parameters.  See
gcc/params.def accessed in the source code using PARAM_VALUE.

	Many other cost models use macros with "COST in their name, such as

TARGET_RTX_COSTS / rtx_cost
BRANCH_COST (and LOGICAL_OP_NON_SHORT_CIRCUIT)
MEMORY_MOVE_COST
REGISTER_MOVE_COST
MAX_CONDITIONAL_EXECUTE
