Bug ID: 48093
Summary: --save-temps generates invalid command lines when
reading from stdin or files whose names start with
hyphens
Product: clang
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: -New Bugs
Assignee: unassignedclangb...@nondot.org
Reporter: richard-l...@metafoo.co.uk
CC: htmldevelo...@gmail.com, llvm-bugs@lists.llvm.org,

Testcase:
$ echo 'int main() {}' | clang -x c++ - -o tmp.o --save-temps
error: unknown argument: '-.ii'
It looks like the driver is not properly escaping filenames that might be
confused for command-line arguments to subtools.
Similarly:
$ touch -- -.c
$ clang ./-.c --save-temps
error: unknown argument: '-.i'
--
