Subject: [driver] Remove obsolete support for -A link option.  The standard -A option is
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=189373170330e3d551bdb28c9762d606f3bcb931;p=clang

[driver] Remove obsolete support for -A link option.  The standard -A option is
used by the preprocessor.  Apple's GCC also supported a -A option for linking.

The ld man page has the following:
 -A basefile - Obsolete incremental load format.  This option is obsolete.

Nick Kledzik confirms this option is no longer needed/supported.
