    • compiler: show readable names in escape analysis messages · cc24ff0d 
          
    Call message_name when printing a variable for an escape analysis
    message.  This implies changing the AST dumps, which is fine.

    • rs6000: Fix safe-indirect-jump-[18].c · b5d0b3d2 
      This patch merges the safe-indirect-jump-1.c and -8.c testcases,
since they do the same thing.  On the 64-bit and AIX ABIs the indirect
call is not a sibcall, since there is code generated after the call
(the restore of r2).  On the 32-bit non-AIX ABIs it is a sibcall.


	* gcc.target/powerpc/safe-indirect-jump-1.c: Build on all targets.
	Make expected output depend on whether we expect sibcalls or not.
	* gcc.target/powerpc/safe-indirect-jump-8.c: Delete (merged into
	safe-indirect-jump-1.c).

    • [AArch64] Fix gcc.target/aarch64/subs_compare_[12].c · de47f61f 
      This patch fixes the testsuite failures gcc.target/aarch64/subs_compare_1.c and subs_compare_2.c
The tests check that we combine a sequence like:
        sub     w2, w0, w1
        cmp     w0, w1

into
        subs    w2, w0, w1

This is done by a couple of peepholes in aarch64.md.

Unfortunately due to scheduling and other optimisations the SUB and CMP
can come in a different order:
        cmp     w0, w1
        sub     w0, w0, w1

And the existing peepholes cannot catch that and we fail to combine the two.
This patch adds a peephole that matches the CMP as the first insn and the SUB as the second
and outputs a SUBS.  This is almost equivalent to the existing peephole that matches SUB first and CMP second
except that it doesn't have the restriction that the output register of the SUB has to not be one of the input registers.
Remember "sub w0, w0, w1 ; cmp w0, w1" is *not* equivalent to: "subs  w0, w0, w1"
but "cmp w0, w1 ; sub w0, w0, w1" is.

So this is what this patch does. It adds a peephole for the case above and one for the SUB-immediate variant
(because the SUB-immediate is represented as PLUS-of-negated-immediate and thus has different RTL structure).

Bootstrapped and tested on aarch64-none-linux-gnu.

    * config/aarch64/aarch64.md: Add peepholes for CMP + SUB -> SUBS
    and CMP + SUB-immediate -> SUBS.
