Ian Lance Taylor 0d3dd8fb65 runtime: copy cgo support from Go 1.7 runtime
Remove support for _cgo_allocate.  It was removed from the gc
    toolchain in Go 1.5, so it is unlikely that anybody is trying to use it.

Janne Blomqvist 7e294024ad Remove unused libgfortran functions
Now that the libgfortran ABI major version has been bumped, we can
remove functions for which the frontend nowadays generates inline
code.

This removes the malloc, free, exponent, fraction, nearest, rrspacing,
spacing, set_exponent and transpose intrinsics. Also the unused
store_exe_path function is removed.

This is another micro-optimisation in change_zero_ext.  If an

Than McIntosh 8220e3f9bd compiler: add containing Bfunction to some backend interfaces.
Change the interfaces for backend methods that create statements to
    always pass in the enclosing Bfunction for the statement.  Having the
    function available simplifies things if a temporary variable has to be
    created during the construction of a statement.
    
    This also includes a change to the Mark_lvalue_varexprs helper
    class to handle indirections on the left hand side of assignments
    (e.g. "*x.y = ...").

The negdi2 patterns for ARM and Thumb-2 are duplicated because Thumb-2
doesn't support RSC with an immediate.  We can however emulate RSC with
zero using a shifted SBC.  If we add this to subsi3_carryin the negdi
patterns can be merged, simplifying things a bit.  This should generate
identical code in all cases.

Wilco Dijkstra c67b6f2683 Thumb uses a special register allocation order to increase the use of low registers.
Thumb uses a special register allocation order to increase the use of low
registers.  Oddly enough, LR appears before R12, which means that LR must
be saved and restored even if R12 is available.  Swapping R12 and LR means
this simple example now uses R12 as a temporary (just like ARM):

int f(long long a, long long b)
{
  if (a < b) return 1;
  return a + b;
}

    gcc/
	* config/arm/arm.c (thumb_core_reg_alloc_order): Swap R12 and R14.

Claudiu Zissulescu d476b53c36 [ARC] Rework ARC600 64-bit multiplication patterns.
Previously users of mulsidi_600 and umulsidi_600 had to take care of
moving the multiplication result into the final destination themselves
(from the MUL64_OUT_REG register).  This commit converts these two
instruction patterns into insn_and_split patterns that now take the
final destination as an extra operand.  The insn_and_split patterns
generate the multiplication using two new multiplication instruction
patterns, then generate the move of the result from the MUL64_OUT_REG
register into the final destination.

This is a clean up commit, there should be no user visible changes
after this commit.

2016-12-16  Claudiu Zissulescu  <claziss@synopsys.com>

	* config/arc/arc.md (mulsidi_600): Change to insn_and_split,
