Although C++ reference types, denoted by DW_TAG_reference_type in

[PR49366] emit loc exprs for C++ non-virtual pmf template value parms
We used to emit, in debug information, the values bound to pointer to
member function template parameters only when they were NULL or
virtual member functions, because those can be represented with
DW_AT_const_value.
In order to represent the symbolic pointer to member function
constants for non-virtual member functions, we'd need to be able to
emit relocations for part of DW_AT_const_value, which we don't. The
more viable alternative is to use DW_AT_location to represent such
values, as slated for inclusion in DWARFv5, according to
<URL:http://www.dwarfstd.org/ShowIssue.php?issue=130412.1>.
With this patch, when we can't emit a DW_AT_const_value, we emit each
"member" of the pointer to member function "record" as a
DW_OP_stack_value DW_OP_piece, as long as the referenced member
function is output in the same translation unit, otherwise we'd get
relocations to external symbols, something to avoid in debug sections.

Insn 26 requires that reg 159 be of class FLOAT_REGS.
first lra action:
deleting insn with uid = 7.
Changing pseudo 159 in operand 1 of insn 26 on equiv [r158:DI]
Creating newreg=164, assigning class ALL_REGS to subreg reg r164
26: r162:DI=unspec[fix(r164:SI#0)] 7
REG_DEAD r159:SI
Inserting subreg reload before:
30: r164:SI=[r158:DI]
[snip]
Change to class FLOAT_REGS for r164
Well, that didn't do much. lra tried the equiv mem, found that didn't
work, and had to reload. Effectively getting back to the two original
insns but r159 replaced with r164. simplify_operand_subreg did not do
anything in this case because SLOW_UNALIGNED_ACCESS was true (wrongly
for power8, but that's beside the point). So now we have, using
abbreviated rtl notation:
r164:SI=[r158:DI]
r162:DI=unspec[fix(r164:SI)]
The problem here is that the first insn isn't valid, due to the rs6000
backend not supporting SImode in fprs, and r164 must be an fpr to make
the second insn valid.
next lra action:
Creating newreg=165 from oldreg=164, assigning class GENERAL_REGS to r165
30: r165:SI=[r158:DI]
Inserting insn reload after:
31: r164:SI=r165:SI
so now we have
r165:SI=[r158:DI]
r164:SI=r165:SI
r162:DI=unspec[fix(r164:SI)]
This ought to be good on power8, except for one little thing.
r165 is GENERAL_REGS so the first insn is good, a gpr load from mem.
r164 is FLOAT_REGS, making the last insn good, a fctiwz.
The second insn ought to be a sldi, mtvsrd, xscvspdpn combination, but
that is only supported for SFmode. So lra continue on reloading the
second insn, but in vain because it never tries anything other than
SImode and as noted above, SImode is not valid in fprs.
What this patch does is arrange to emit the two reloads needed for the
SLOW_UNALIGNED_ACCESS case at once, moving the subreg to the second
insn in order to switch modes, producing:
I've also tidied a couple of other things:
1) "old" is unnecessary as it duplicated "operand".
2) Rejecting mem subregs due to SLOW_UNALIGNED_ACCESS only makes sense
if the original mode was not slow.

[RS6000] e500 part of pr71680
The fallback part of HARD_REGNO_CALLER_SAVE_MODE, choose_hard_reg_mode,
returns DFmode for SImode when TARGET_E500_DOUBLE. This confuses
lra when attempting to save ctr around a call.

compiler: rewrite compiler directive support
Rewrite the compiler directive support to recognize all the compiler
directives implemented by the current gc compiler. The directives other
than go:linkname are now turned into GOPRAGMA flags attached to a
function or function declaration. The go:linkname directive is turned
into a map attached to the Lex object. No new directives are actually
implemented yet, they are just recognized.
This patch fixes an bootstrap error with autoprofiledbootstrap
due to uninitiliazed variables, because the compiler cannot
figure out they don't need to be initialized in an error path.
Just always initialize them.

There were some reports that the autofdo tests are non deterministic

- Don't print file names in the test log because the directories
can vary (suggested by Jeff Law)

text/template: reduce maxExecDepth for gccgo further
We already lowered the limit of recursive template invocations from
100,000 to 10,000, but the tests still fail occasionally on
x86_64-pc-linux-gnu when using GNU ld (so that split stacks are not
fully functional). Reduce the limit further, to 1000, enough so that
the test passes consistently.
Permitting 1000 recursive template invocations still seems capacious
enough for real world use.

c-format.c: suggest the correct format string to use (PR c/64955)
This adds fix-it hints to c-format.c so that it can (sometimes) suggest
the format string the user should have used.
The patch adds selftests for the new code in c-format.c. These
selftests are thus lang-specific. This is the first time we've had
lang-specific selftests, and hence the patch also adds a langhook for
running them. (Note that currently the Makefile only invokes the
selftests for cc1).
