Subject: [Support] Use FILE_SHARE_DELETE to fix RemoveFileOnSignal on Windows
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=4ae50e81b9a7c35f26a10bb103b8d46bfb6cf290;p=clang

[Support] Use FILE_SHARE_DELETE to fix RemoveFileOnSignal on Windows

Summary:
Tools like clang that use RemoveFileOnSignal on their output files
weren't actually able to clean up their outputs before this change.  Now
the call to llvm::sys::fs::remove succeeds and the temporary file is
deleted. This is a stop-gap to fix clang before implementing the
solution outlined in PR34070.
