[PATCH] powerpc: Cleanup LOADADDR etc. asm macros

2006-01-13T10:16:23+00:00

This patch consolidates the variety of macros used for loading 32 or
64-bit constants in assembler (LOADADDR, LOADBASE, SET_REG_TO_*).  The
idea is to make the set of macros consistent across 32 and 64 bit and
to make it more obvious which is the appropriate one to use in a given
situation.  The new macros and their semantics are described in the
comments in ppc_asm.h.

In the process, we change several places that were unnecessarily using
immediate loads on ppc64 to use the GOT/TOC.  Likewise we cleanup a
couple of places where we were clumsily subtracting PAGE_OFFSET with
asm instructions to use assemble-time arithmetic or the toreal() macro
instead.

[PATCH] powerpc: Fix use of LOADBASE in merge tree

2005-10-17T11:43:12+00:00

The merge-tree version of LOADBASE actually loads the whole given
address from the toc for ppc64.  The matching OFF macro adjust for
this, using an offset of 0 for ppc64, but we weren't using that in
power4_idle.

powerpc: merge idle_power4.S and trapc.s

2005-10-01T08:43:42+00:00

Use idle_power4.S from ppc64 as we are not going to support
32 bit power4 in the merged tree.

Merge ppc64 traps.c into powerpc traps.c:
	use ppc64 versions of exception routine names
		(as they don't have StudlyCaps)
	make all the versions if die() have the same
		prototype
