clangd broke because it can't look through symlinks. compile_commands manipulation does not fix it, clangd configuration does not fix it, a vfs overlay does not fix it, and while a combination of those can fix it with a bind mount in place that's just too cursed to even consider clangd bug: https://github.com/llvm/llvm-project/issues/116877 Change-Id: I8e3e8489548eb3a7aa65ac9d12a5ec8abf814aec

// This stuff is here to force the compiler to actually apply the extern
|
|
// template directives in all compilation units. To borrow a term, under
|
|
// complex microarchitectural conditions, clang ignores the extern template
|
|
// declaration, as revealed in the profile.
|
|
//
|
|
// In most cases, extern template works fine in the header itself. We don't
|
|
// have any idea why this happens.
|
|
|
|
// Here because of all the regexes everywhere (it is infeasible to block instantiation everywhere)
|
|
// For some reason this does not actually prevent the instantiation of
|
|
// regex::_M_compile, and the regex compiler (my interpretation of what this is
|
|
// supposed to do is make the template bits out-of-line), but it *does* prevent
|
|
// a bunch of codegen of regex stuff, which seems to save about 30s on-cpu.
|
|
// Instantiated in libutil/regex.cc.
