Bug ID: 50033
Summary: -fno-temp-file is broken in clang 12
Product: clang
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: release blocker
Priority: P
Component: Frontend
Assignee: [email protected]

Creating a pch with -fno-temp-file set creates a temp file because
*RemoveFileOnSignal=*/false
Traced back to ad7aaa475e5e632242b07380ec47d2f35d077209
A simplified command line is as follows:
clang-cl -fno-temp-file /Yc /Fpstdafx.pch /Fostdafx.obj stdafx.h
Observer in your favorite system monitor (such as procmon) that a temp file is
created.
Without hacking up our internal fork of clang this completely blocks adoption
of clang 12.
