rs6000.h (read_only_data_section, [...]): Align CSECT on doubleword boundary for 64-bit target.

Browse Source 
* rs6000.h (read_only_data_section, private_data_section,
	read_only_private_data_section, toc_section): Align CSECT on
	doubleword boundary for 64-bit target.
	(DATA_SECTION_ASM_OP): Likewise.
	* rs6000.c (rs6000_stack_info): Leaf procedure stack limit is 288.
