Subject: [fixincludes, v3] Don't define libstdc++-internal macros in Solaris 10+ <math.h>
Date: Thu, 03 Nov 2016 14:11:00 -0000 [thread overview]
Message-ID: <yddy410lkld.fsf@CeBiTec.Uni-Bielefeld.DE> (raw)
[-- Attachment #1: Type: text/plain, Size: 6750 bytes --]
As I've noticed some time ago, recent versions of Solaris <math.h>
include this little gem:
#if __cplusplus >= 201103L
#undef _GLIBCXX_USE_C99_MATH
#undef _GLIBCXX_USE_C99_MATH_TR1
#endif
This renders a couple of perfectly good libstdc++ tests as UNSUPPORTED
and is completely unsustainable. Agreement has now been reached with
the Solaris libm maintainers that this wasn't a good idea and the plan
is to do away with it at least in future Solaris 11.3 SRUs and Solaris 12.
Some digging discovered that we have 3 levels of support in <math.h> and
<iso/math_c99.h:
1) No C++11 math support at all.
2) Overloads for C++11 math functions, already handled by
[v3] Handle C++11 <math.h> overloads on Solaris 12
https://gcc.gnu.org/ml/gcc-patches/2015-11/msg02075.html
and the 4.9 backport
[v3, 4.9] Handle C++11 <math.h> overloads on Solaris 11, 12
https://gcc.gnu.org/ml/gcc-patches/2016-02/msg01477.html
They were introduced in Solaris 10 Patch 11996[67]-02, Solaris 11.3
SRU 3.6, and Solaris 12 Build 86.
3) Full C++11 math support, including the templates present in libstdc++
<cmath>, and the #undef's above.
Introduced in the same Solaris 10 Patch, Solaris 11.3 SRU 5.6, and
Solaris 12 Build 90.
To check for potential fallout, I've added a fixincludes fix to remove
the #undefs. As expected, there was quite a bit, e.g.
+FAIL: 25_algorithms/pop_heap/complexity.cc (test for excess errors)
+WARNING: 25_algorithms/pop_heap/complexity.cc compilation failed to produce executable

due to duplicate log2 templates in <iso/math_c99.h> and c_global/cmath,
and many more of the same kind.
Fortunately, this is all easily fixed by wrapping the affected templates
in a new macro. That's what this patch does. The new libstdc++
acinclude.m4 test may well need wording changes in comments etc. and can
perhaps be shortened a bit, bit it worked for me.
The fixincludes part passes make check.
The patch has been regtested (C++ only) on
* Solaris 11.2 SRU 13.6 (i.e. without both overloads and templates in
<iso/math_c99.h>),
* Solaris 11.3 SRU 3.6 (i.e. with overloads only), and
* Solaris 12 Build 110 (i.e. with both overloads and templates, and the
_GLIBCXX_USE_C99_MATH #undef's)
* Linux/x86_64
I've checked that __CORRECT_ISO_CPP11_MATH_H_PROTO[12] were defined in
config.h as expected, and there were no testsuite regressions. On the
contrary, a couple of tests that before showed up as UNSUPPORTED due to
the _GLIBCXX_USE_C99_MATH* #undef's now PASS as they should.
Ok for mainline now, and for backports to the gcc-6 and gcc-5 branches
after some soak time?
Thanks.
Rainer
