Ping... Hi, when the free-standing libstdc++-headers are installed, the C++ header file <new> does not always compile, because it includes <exception> and this includes under certain conditions (__cplusplus >= 201103L && ATOMIC_INT_LOCK_FREE > 1) the header file <bits/nested_exception.h> but that fails to compile because it needs <bits/move.h> which is not installed. This condition depends on the target, and for instance an arm-eabi eCos compiler fails to compile <new> with -mcpu=cortex-a9 and the default C++ standard option, while it is OK with ARMv4 CPUs. Therefore this patch adds move.h and concept_check.h to the installed headers, unconditionally. I've verified that the <new> header compiles on an eCos cross compiler. Boot-strapped and regression-tested on x86_64-pc-linux-gnu. Is it OK for trunk? Thanks Bernd.
Hi, I am pinging for this patch, which addresses an admittedly minor regression for free-standing libstdc++ due to changed c++11 default settings. The proposed patch does only change the free-standing install rule, and has therefore no impact on other configurations. https://gcc.gnu.org/ml/libstdc++/2016-03/msg00004.html Thanks Bernd.
