◆ addr_for_mem_ref() [1/2]
|
extern |
Returns address for TARGET_MEM_REF with parameters given by ADDR in address space AS. If REALLY_EXPAND is false, just make fake registers instead of really expanding the operands, and perform the expansion in-place by using one of the "templates".

◆ addr_for_mem_ref() [2/2]
|
extern |
implement addr_for_mem_ref() directly from a tree, which avoids exporting the mem_address structure.

◆ copy_ref_info()
Copies the reference information from OLD_REF to NEW_REF, where NEW_REF should be either a MEM_REF or a TARGET_MEM_REF.

Creates and returns a TARGET_MEM_REF for address ADDR. If necessary computations are emitted in front of GSI. TYPE is the mode of created memory reference. IV_CAND is the selected iv candidate in ADDR, and BASE_HINT is non NULL if IV_CAND comes from a base address object.

◆ maybe_fold_tmr()

◆ move_fixed_address_to_symbol()

extern |
If ADDR contains an address of object that is a link time constant, move it to PARTS->symbol.

◆ preferred_mem_scale_factor()
Return the preferred index scale factor for accessing memory of mode MEM_MODE in the address space of pointer BASE. Assume that we're optimizing for speed if SPEED is true and for size otherwise.
