    • Fix a typo in two_value_replacement function · 94adc935 
      GCC revision 267634 implemented two_value_replacement function.
However, a typo occurred during the parameter check, which caused
us to miss some optimizations.

The intent of the code might be to check that the input parameters
are const int and their difference is one.  However, when I read
the code, I found that it is wrong to detect whether an input data
plus one is equal to itself.  This could be a typo.

    • PR libstdc++/90299 make filesystem::absolute overloads consistent · 854a5c77 
      In this implementation it is an error to pass the empty path to absolute,
because the empty path doesn't represent any file in the filesystem so
the function cannot meet its postcondition.

Currently the absolute(const path&, error_code&) overload reports an
error for the empty path, but using errc::no_such_file_or_directory, and
the other overload does not report an error. This patch makes them
consistntly report an errc::invalid_argument error for the empty path.

	PR libstdc++/90299
	* src/c++17/fs_ops.cc (absolute(const path&)): Report an error if the
	argument is an empty path.
	(absolute(const path&, error_code&)): Use invalid_argument as error
	code instead of no_such_file_or_directory.
	* testsuite/27_io/filesystem/operations/absolute.cc: Check handling
	of non-existent paths and empty paths with both overloads of absolute.
