C++98 and C++03 are effectively aliases as far as Clang is concerned.
As such, allowing both std=c++98 and std=c++03 as Lit parameters is
just slightly confusing, but provides no value. It's similar to allowing
both std=c++17 and std=c++1z, which we don't do.
This was discovered because we had an internal bot that ran the test
suite under both c++98 AND c++03 -- one of which is redundant.
Differential Revision: https://reviews.llvm.org/D80926
The testing script used to test libc++ historically did not like directories
without any testing files, so these tests had been added. Since this is
not necessary anymore, we can now remove these files. This has the benefit
that the total number of tests reflects the real number of tests more
closely, and we also skip some unnecessary work (especially relevant when
running tests over SSH).
However, some nothing_to_do.pass.cpp tests actually serve the purpose of
documenting that an area of the Standard doesn't need to be tested, or is
tested elsewhere. These files are not removed by this commit.
Removal done with:
import os
import itertools
for (dirpath, dirnames, filenames) in itertools.chain(os.walk('./libcxx/test'),
os.walk('./libcxxabi/test')):
if len(filenames + dirnames) > 1 and \
any(p == 'nothing_to_do.pass.cpp' for p in filenames):
os.remove(os.path.join(dirpath, 'nothing_to_do.pass.cpp'))
