Subject: Simple little smoke-test script that tries to build PCH files and then
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=69a6b6d7fcf57fa0603214d46484aa2c73f5d884;p=clang

Simple little smoke-test script that tries to build PCH files and then
dump their contents for all of the compilable tests in Clang's
testsuite. All of the tests pass for C, but there are still many
failures for Objective-C.
