Compilation command line and outputs/dumps
Got parsing bugs like:
1. /Users/duzy/workspace/toolchain/source/extcxx/include/execution:4967:2:
current parser token ';'
2. /Users/duzy/workspace/toolchain/source/extcxx/include/execution:869:1
<Spelling=/Users/duzy/workspace/.out/x86_64-unknown-darwin-gnu/building/include/c++/v1/__config:765:37>:
parsing namespace 'std'
3. /Users/duzy/workspace/toolchain/source/extcxx/include/execution:869:1
<Spelling=/Users/duzy/workspace/.out/x86_64-unknown-darwin-gnu/building/include/c++/v1/__config:765:60>:
parsing namespace 'std::__extbit_1'

<Spelling=/Users/duzy/workspace/.out/x86_64-unknown-darwin-gnu/building/include/c++/v1/__config:780:71>:

5. /Users/duzy/workspace/toolchain/source/extcxx/include/execution:869:1
<Spelling=/Users/duzy/workspace/.out/x86_64-unknown-darwin-gnu/building/include/c++/v1/__config:780:100>:
parsing namespace 'std::__extbit_1::execution::v1'
6.
/Users/duzy/workspace/toolchain/source/extcxx/include/execution:4958:35:
parsing struct/union/class body 'std::__extbit_1::execution::v1::crash_test'
While compiling code segment looks like this:
template <typename InnerProperty> struct crash_test
{
template <typename Executor, typename Property>
friend constexpr void crash(const Executor& ex, const crash_test<Property>&
p,
enable_if_t<is_same_v<Property, InnerProperty> /*&& can_prefer_v<const
Executor&, const InnerProperty&>*/>* = 0)
noexcept(/*is_nothrow_prefer<const Executor&, const
InnerProperty&>::value*/true)
{
return _VSTD::prefer(ex, p.property);
}
};</pre>
