hooks.c (hook_rtx_rtx_identity): Generic hook function that takes a single rtx and returns it unmodified.
* hooks.c (hook_rtx_rtx_identity): Generic hook function that
takes a single rtx and returns it unmodified.
* hooks.h (hook_rtx_rtx_identity): Prototype here.
* target.h (struct gcc_target): Add "delegitimize_address"
field to target structure.
* target-def.h (TARGET_DELEGITIMIZE_ADDRESS): Provide default
for delegitimize_address target using hook_rtx_rtx_identity.
(TARGET_INITIALIZER): Initialize delegitimize_address field
using TARGET_DELEGITIMIZE_ADDRESS macro.
* simplify-rtx.c (avoid_constant_pool_reference): Handle float
extensions of constant pool references. Use delegitimize_address
to undo the obfuscation of "-fpic".
* Makefile.in (simplify-rtx.o): Add dependency on target.h.
* config/i386/i386.c (TARGET_DELEGITIMIZE_ADDRESS): Define as
i386_simplify_dwarf_addr.
(ix86_find_base_term): Simplify using i386_simplify_dwarf_addr.
(maybe_get_pool_constant): Likewise.
