Subject: Changed -serialize-ast to not create a temporary directory, but instead
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=3821d401a3f338aef5e80a83e5b0214c4160d9ce;p=clang

Changed -serialize-ast to not create a temporary directory, but instead
create a .ast file in the current working directory.  This mirrors the behavior
of the -c option for gcc.  Later we should add the ability to write the
serialized file anywhere.
