aganea added inline comments.
================
Comment at: clang/lib/Driver/Driver.cpp:3782
+ = Cmd.getProcessStatistics();
+ if (ProcStat) {
+ if (PrintProcessStat) {
----------------
In the case where `!ProcStat`, I am wondering if we shouldn't emit zero values,
in the report file at least. Otherwise if an invocation fails, it won't be
there in the report and we might wonder why. Emitting 0 might indicate that
something went wrong.
================
Comment at: clang/lib/Driver/Driver.cpp:3814
+ llvm::raw_fd_ostream OS(StatReportFile, EC,
llvm::sys::fs::OF_Append);
+ if (!EC) {
+ if (auto L = OS.tryToLock())
----------------
If the goal is to report accurate information, maybe it's worth looping here a
bit in case of an error, to give the chance to other clang.exe instances to
release the file lock? What do you think? (same for `tryToLock`)
