    • Correct libgcc complex multiply excess precision handling (PR libgcc/77519). · d758aeb5 
      libgcc complex multiply is meant to eliminate excess
precision from certain internal values by forcing them to memory in
exactly those cases where the type has excess precision.  But in
https://gcc.gnu.org/ml/gcc-patches/2014-09/msg01894.html I
accidentally inverted the logic so that values get forced to memory in
exactly the cases where it's not needed.  (This is a pessimization in
the no-excess-precision case, in principle could lead to bad results
depending on code generation in the excess-precision case.  Note: I do
not have a test demonstrating bad results.)

Bootstrapped with no regressions on x86_64-pc-linux-gnu.  Code size
went down on x86_64 as expected; old sizes:

   text    data     bss     dec     hex filename
    887       0       0     887     377 _muldc3.o
    810       0       0     810     32a _mulsc3.o
   2032       0       0    2032     7f0 _multc3.o
    983       0       0     983     3d7 _mulxc3.o

New sizes:

    847       0       0     847     34f _muldc3.o
    770       0       0     770     302 _mulsc3.o

    • Improve aarch64_legitimize_address - avoid splitting the offset if it is supported. · ff0f3f1c 
      Improve aarch64_legitimize_address - avoid splitting the offset if it is
supported.  When we do split, take the mode size into account.  BLKmode
falls into the unaligned case but should be treated like LDP/STP.
This improves codesize slightly due to fewer base address calculations:

int f(int *p) { return p[5000] + p[7000]; }

Now generates:

f:
	add	x0, x0, 16384
	ldr	w1, [x0, 3616]
	ldr	w0, [x0, 11616]
	add	w0, w1, w0
	ret

instead of:

f:
	add	x1, x0, 16384
	add	x0, x0, 24576
	ldr	w1, [x1, 3616]
	ldr	w0, [x0, 3424]
	add	w0, w1, w0
	ret

    gcc/
	* config/aarch64/aarch64.c (aarch64_legitimize_address):
	Avoid use of base_offset if offset already in range.
