ffc2fc06e3 x86: Update __CET__ check 
__CET__ has been changed by revision 259522:

commit d59cfa9a4064339cf2bd2da828c4c133f13e57f0
Author: hjl <hjl@138bc75d-0d04-0410-961f-82ee72b054a4>
Date:   Fri Apr 20 13:30:13 2018 +0000

    Define __CET__ for -fcf-protection and remove -mibt

to

    (__CET__ & 1) != 0: -fcf-protection=branch or -fcf-protection=full
    (__CET__ & 2) != 0: -fcf-protection=return or -fcf-protection=full

We should check (__CET__ & 2) != 0 for shadow stack.

	when including "config/i386/shadow-stack-unwind.h".

14e335edc8 CET shouldn't be enabled in 32-bit run-time libraries by defualt 
ENDBR32 and RDSSPD are multi-byte NOPs on x86-64 processors and
newer x86 processors, starting Pentium Pro.  They are UD on older
32-bit processors. Detect this at configure time and adjust the
default value for enable_cet. GCC will enable CET in 32-bit run-time
libraries in any case if --enable-cet is used to configure GCC.

cc03e55b5a Add extra field to gtm_jmpbuf on x86 only 
Expand the gtm_jmpbuf structure by one word field to add
Intel CET support further. The code in sjlj.S already
allocates more space on the stack then gtm_jmpbuf needs.
Use this extra space to absorb the new field.

The structure is allocated on the stack in such a way
that eip/rsp field is overlapped with return address on
the stack. Locate the new field right before eip/rsp so
code that accesses buffer fields relative to address of
gtm_jmpbuf has its offsets unchanged.

	* libitm/config/x86/target.h: Add new field (ssp).
	* libitm/config/x86/sjlj.S: Change offsets.

edcbda7e2c libitm: Introduce target macro TARGET_BEGIN_TRANSACTION_ATTRIBUTE. 
The attached patch adds the a target specific attribute via the
new target macro TARGET_BEGIN_TRANSACTION_ATTRIBUTE to the
function begin_transaction().  S/390 uses this to set the
soft-float target attribute which is needed to fix a crash with
-m31.

As there seems to be no place in libitm to document internal macros like
USE_HTM_FASTPATH or the new macro, I've put the documentation in a
comment where the macro is used.

9e531d3749 Testsuite: add dg-{begin|end}-multiline-output commands 
This patch adds an easy way to write tests for expected multiline
output.  For example we can test carets and underlines for
a particular diagnostic with:

/* { dg-begin-multiline-output "" }
 typedef struct _GMutex GMutex;
                ^~~~~~~
   { dg-end-multiline-output "" } */

multiline.exp is used by prune.exp; hence we need to load it before
prune.exp via *load_gcc_lib* for the testsuites of the various
non-"gcc" support libraries (e.g. boehm-gc).

gcc/testsuite/ChangeLog:
	* lib/multiline.exp: New file.
	* lib/prune.exp: Load multiline.exp.
	(prune_gcc_output): Call into multiline.exp to handle any
	multiline output directives.
	* lib/libgo.exp: Load multiline.exp before prune.exp, using
	load_gcc_lib.
