S/390: Fix mtune default.

When building with --with-tune=zEC12 and calling the resulting gcc
with --march=z13 (no extra -mtune), the binary would unexpectedly be compiled
with -march=z13 -mtune=zEC12.  This patch avoids using the default tune
parameter if -march is specified as argument but the user can still
explicitly state -march=z13 -mtune=zEC12.

Jonathan Wakely [Thu, 21 Jun 2018 23:29:01 +0000 (00:29 +0100)]
PR libstdc++/86138 prevent implicit instantiation of COW empty rep

The explicit instantiation declarations for std::basic_string are
disabled for C++17 (and later) so that basic_string symbols get
implicitly instantiated in every translation unit that needs them.  On
targets that don't support STB_GNU_UNIQUE this leads to multiple copies
of the empty rep symbol for COW strings. In order to detect whether a
COW string needs to deallocate its storage it compares the address with
the empty rep.  When there are multiple copies of the empty rep object
the address is not unique, and so string destructors try to delete the
empty rep, which crashes.

In order to guarantee uniqueness of the _S_empty_rep_storage symbol this
patch adds an explicit instantiation declaration for just that symbol.
This means the other symbols are still implicitly instantiated in C++17
code, but for the empty rep the definition in the library gets used.

Separately, there is no need for C++17 code to implicitly instantiate
the I/O functions for strings, so this also restores the explicit
instantiation declarations for those functions.

The SSO basic_string has a non-standard insert(iterator, initializer_list)

6 years ago[testsuite] Fix guality/pr45882.c for flto
Tom de Vries [Thu, 21 Jun 2018 13:37:59 +0000 (13:37 +0000)]
[testsuite] Fix guality/pr45882.c for flto

Atm this test in pr45882.c fails:
...
  int d = a[i];  /* { dg-final { gdb-test 16 "d" "112" } } */
...
as follows:
...
FAIL: gcc.dg/guality/pr45882.c   -O2 -flto -fuse-linker-plugin \
      -fno-fat-lto-objects  line 16 d == 112
...

In more detail, gdb fails to print the value of d:
...
Breakpoint 1, foo (i=i@entry=7, j=j@entry=7) at pr45882.c:16
16        ++v;
$1 = <optimized out>
$2 = 112
<optimized out> != 112
...

Variable d is a local variable in function foo, initialized from global array a.
When compiling, first cddce1 removes the initialization of d in foo, given
that d is not used afterwards.  Then ipa marks array a as write-only, and
removes the stores to array a in main.  This invalidates the location
expression for d, which points to a[i], so it is removed, which is why gdb
ends up printing <optimized out> for d.

This patches fixes the fail by adding attribute used to array a, preventing
array a from being marked as write-only.

Tested on x86_64.

2018-06-21  Tom de Vries  <tdevries@suse.de>

* gcc.dg/guality/pr45882.c (a): Add used attribute.
