Spelling out the iterator unstable_remove_if returned named libstdc++'s own __gnu_cxx::__normal_iterator, which only libstdc++ has: the Android, macOS and Windows builds (libc++, MSVC) failed on page_tracker.cpp. The two handle-list sweeps are now plain index loops that swap a dropped handle with the last kept one and cut the tail off, the same compaction in the same order, with no iterator, lambda or library-specific type in them. tests/stdlib fails when a core source names a standard library's internals, and syntax-checks every C++ unit of the CMake build against libc++; the test workflow installs clang and libc++ for it.

"""Syntax-checks every C++ unit of a configured CMake build.
|
|
|
|
Usage: sweep.py <compile_commands.json>
|
|
|
|
Each unit's own compile command is run with -fsyntax-only in place of
|
|
-c/-o, in parallel. A unit whose source is generated during the build
|
|
(and so is not there yet) is skipped. Exits non-zero if any unit fails,
|
|
or if there was nothing to check.
