2015-11-26[PR67753] adjust for padding when bypassing memory in assign_parm_setup_blockAlexandre Oliva2-3/+48
Storing a register in memory as a full word and then accessing the same memory address under a smaller-than-word mode amounts to right-shifting of the register word on big endian machines. So, if BLOCK_REG_PADDING chooses upward padding for BYTES_BIG_ENDIAN, and we're copying from the entry_parm REG directly to a pseudo, bypassing any stack slot, perform the shifting explicitly. This fixes the miscompile of function_return_val_10 in gcc.target/aarch64/aapcs64/func-ret-4.c for target aarch64_be-elf introduced in the first patch for 67753. for gcc/ChangeLog PR rtl-optimization/67753 PR rtl-optimization/64164 * function.c (assign_parm_setup_block): Right-shift upward-padded big-endian args when bypassing the stack slot.
