[PATCH] D68033: [llvm-ar] Make paths case insensitive when on windows

[Owen Reynolds via Phabricator via llvm-commits]

gbreynoo added a comment.

My understanding is that although NTFS is case sensitive, the windows API makes file operations case insensitive by default.

This means on Windows the two paths below are functionally the same:

1. c:\a\path\example
2. C:\A\PATH\EXAMPLE

As your snippet shows, gnu-ar treats these paths as the same when on Windows when doing member name comparisons e.g. when using the replace command one path will replace the other.

Under current llvm-ar behaviour they are considered as two different paths. If path 1 is stored in an archive, you can not select the member using path 2.

This diff was put up for review to keep behaviour consistent with gnu-ar and with default windows path behaviour.
