f174328efe i386: Avoid stack realignment if possible 
ix86_finalize_stack_frame_flags has been extended to eliminate frame
pointer when the new stack frame isn't needed with and without
-maccumulate-outgoing-args as well as -fomit-frame-pointer.  Since stack
access with larger alignment may be optimized out, to decide if stack
realignment is needed, we need to not only check for stack frame access,
but also verify the alignment of stack frame access.  Since alignment of
memory access via arg_pointer is set up by caller, not by callee, we
should find the maximum stack alignment from the stack frame access
instructions via stack pointer and frame pointrer to avoid stack
realignment when stack alignment needed is less than incoming stack
boundary.

ae85ad3a95 Improve alloca alignment 
This patch improves alloca alignment.  Currently alloca reserves
too much space as it aligns twice, and generates unnecessary stack
alignment code.

When the requested alignment is lower than the stack alignment, no
extra alignment is needed.  If the requested alignment is higher,
we need to increase the size by the difference of the requested 
alignment and the stack alignment.  As a result, the alloca alignment
is exactly as expected:

alloca (16):
	sub	sp, sp, #16
	mov	x1, sp

alloca (x):
	add	x0, x0, 15
	and	x0, x0, -16
	sub	sp, sp, x0
	mov	x0, sp

__builtin_alloca_with_align (x, 512):
	add	x0, x0, 63
	and	x0, x0, -16
	sub	sp, sp, x0
	add	x0, sp, 63
	and	x0, x0, -64

80ec73f4ee Turn HARD_REGNO_CALL_PART_CLOBBERED into a target hook 
The SVE patches change the size of a machine_mode from a compile-time
constant to a runtime invariant.  However, target-specific code can
continue to treat the modes as constant-sized if the target only has
constant-sized modes.

The main snag with this approach is that target-independent code still
uses macros from the target .h file.  This patch is one of several that
converts a target macro to a hook.

db69559bac PR82045: Avoid passing machine modes through "..." 
PR82045 is about a bootstrap failure on sparc-sun-solaris2.11.
The problem was that we were passing the new machine_mode wrapper
classes through "..."  to emit_library_call(_value), which then
read them back as ints instead.

The simplest fix seemed to be replace "..." with an array of
rtx_mode_ts, then provide wrappers for the common cases.  This
bulks out rtl.h a bit, but it does make things a bit more typesafe.

0c949f0a1c re PR libquadmath/81848 (Add PowerPC support to libquadmath) 
2017-09-01  Michael Meissner  <meissner@linux.vnet.ibm.com>

	PR libquadmath/81848
	* configure.ac (powerpc*-linux*): Use attribute mode KC to create
	complex __float128 on PowerPC instead of attribute mode TC.
	* quadmath.h (__complex128): Likewise.
	* configure: Regenerate.
	* math/cbrtq.c (CBRT2): Use __float128 not long double.
	(CBRT4): Likewise.
	(CBRT2I): Likewise.
	(CBRT4I): Likewise.
	* math/j0q.c (U0): Likewise.
	* math/sqrtq.c (sqrtq): Don't depend on implicit conversion
	between __float128, instead explicitly convert the __float128
	value to long double because the PowerPC does not allow __float128
	and long double in the same expression.
