DYLD_LIBRARY_PATH is now removed from the environment for all system
tools, including the shell. Adapt the testsuite and pass the right
options to allow testing, even when the compiler and libraries have not
been installed.
gcc/ChangeLog:
* Makefile.in: set ENABLE_DARWIN_AT_RPATH in site.tmp.
gcc/testsuite/ChangeLog:
* gfortran.dg/coarray/caf.exp: Correctly set
libatomic flags.
* gfortran.dg/dg.exp: Likewise.
* lib/asan-dg.exp: Set correct -B flags.
* lib/atomic-dg.exp: Likewise.
* lib/target-libpath.exp: Handle ENABLE_DARWIN_AT_RPATH.
libatomic/ChangeLog:
* testsuite/lib/libatomic.exp: Pass correct flags on darwin.
libffi/ChangeLog:
* testsuite/lib/libffi.exp: Likewise.
libitm/ChangeLog:
* testsuite/lib/libitm.exp: Likewise.
* testsuite/libitm.c++/c++.exp: Likewise.
This removes the helper functions added by r8-1294 to detect whether the
char_traits member functions can be evaluated at compile time. Instead,
we can just use __builtin_constant_evaluated directly, which is well
supported by non-GCC compilers by now.
As a result, there is a chance that those members will no longer be
usable in constant expressions when using old versions of non-GCC
compilers. Make the relevant feature test macros depend on the
availability of __builtin_constant_evaluated, so they are defined only
when the feature is actualyl available.
The new testcase from the PR is added to the libitm testsuite, because
that's where we can be sure it's OK to use the -fgnu-tm option.
