Description Sebastian Hahn 2011-04-10 21:13:22 PDT 
gcc supports the "--param ssp-buffer-size=1" argument, but it seems that clang doesn't recognize it (yet). Are there plans to add this functionality, or is there something preventing it from being added?

It would be nice to see this bug implemented. It causes almost 100 failures in the rebuild of Debian with clang :

This seems to correspond to LLVM's -stack-protector-buffer-size, so it's just
a matter of wiring it up.

Attached patches.  Still need llvm codegen test case. (Offers welcome :)

The LLVM patch looks good to me.
Comment 7 Chad Rosier 2012-08-21 11:17:04 PDT 
This should be resolved with r162284/162285.

Thanks Chad!
Comment 9 Anders Kaseorg 2013-03-07 16:18:49 PST 
Can we also make clang accept and ignore this argument when linking but not compiling (bug 15327)?
