Makefile.in (expr.o): Depend on $(TARGET_H).
* Makefile.in (expr.o): Depend on $(TARGET_H).
* target.h (return_in_msb): New target hook.
* target-def.h (TARGET_RETURN_IN_MSB): New macro.
(TARGET_CALLS): Include it.
* calls.c (shift_returned_value): New function.
(expand_call): Use it.
* expr.c: Include target.h.
(copy_blkmode_from_reg): Check targetm.calls.return_in_msb when
deciding what padding is needed. Change the name of the local
padding variable from big_endian_correction to padding_correction.
* stmt.c (shift_return_value): New function.
(expand_return): Use it. Adjust memory->register copy in the same
way as copy_blkmode_from_reg. Only change the return register's
mode if it was originally BLKmode.
* doc/tm.texi (TARGET_RETURN_IN_MSB): Document.
* config/mips/mips.c (TARGET_RETURN_IN_MSB): Define.
(mips_fpr_return_fields): New, split out from mips_function_value.
(mips_return_in_msb, mips_return_fpr_pair): New functions.
(mips_function_value): Rework to use the functions above.
* config/mips/irix6-libc-compat.c: Delete.
* config/mips/t-iris6 (LIB2FUNCS_STATIC_EXTRA): Undefine.
