[PATCH], PR target/60876 -- fix build issue with powerpc

[Michael Meissner]

[-- Attachment #1: Type: text/plain, Size: 621 bytes --]

I committed the following patch as obvious to fix the PowerPC build issue that
came up with changes to machmode.h.  These changes allow the compiler to build
and bootstrap. Submitted as subversion id 209498.

2014-04-17  Michael Meissner  <meissner@linux.vnet.ibm.com>

	PR target/60876
	* config/rs6000/rs6000.c (rs6000_setup_reg_addr_masks): Make sure
	GET_MODE_SIZE gets passed an enum machine_mode type and not
	integer.
	(rs6000_init_hard_regno_mode_ok): Likewise.
