Subject: Schedule discriminator pass.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=e1e6798cc7a56ce249c97ab470033e446acb66ba;p=clang

Schedule discriminator pass.

This needs to modify a line table test to account for the new lexical
block created to hold the new discriminator value.
