One of the simulators we use for testing nios2-elf builds doesn't
include full semihosted fileio support. (IIRC it can do I/O to the
console and open and close files, but doesn't support fseek, stat/fstat,
unlink, etc). There are a bunch of libstdc++ wchar_t/$test.cc test
cases that fail on this target where the corresponding char/$test.cc
test is skipped, because the char test case files already specify
"dg-require-fileio" and the wchar_t ones don't.
I used grep etc to find all such pairs of test cases, and then added
"dg-require-fileio" to the wchar_t files where it was missing. Note
that this patch touches more test cases than the ones that were actually
failing, and I didn't confirm that all the similarly-named char and
wchar_t files were actually testing the exact same things.
Is this OK to check in? Or is some deeper analysis required to identify
which tests are affected?
