Bug ID: 41268
Summary: Fail hard (or support) wildcard characters
Product: tools
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: llvm-objcopy/strip

Several GNU objcopy/strip commands support glob-like syntax by default, such
as:
"strip --remove-section=.text.* --remove-section=!.text.foo". It seems the
characters supported are: *, !, ?, \, [, ].
My personal opinion is that the --regex flag we added to llvm-objcopy is better
than this and we shouldn't carry this legacy syntax forward, but one downside
we currently have is people using strip/objcopy may not notice these flags
aren't working -- e.g. "--remove-section=.text.*" will try to remove a section
literally called ".text.*" and end up not removing anything. Instead, we should
return an error to make it more visible that the user needs to use a different
syntax (regex instead of globs) and also pass --regex.
(Or, we could support globs, though I don't think anyone is in favor of that).
