[libvirt] [PATCH] maint: detect clang 2.9

In Fedora 15, with clang 2.8, 'scan-build env' shows: CCC_ANALYZER_ANALYSIS=-analyzer-check-objc-mem -analyzer-check-security-syntactic -analyzer-check-dead-stores -analyzer-check-objc-unused-ivars -analyzer-check-objc-methodsigs But in rawhide, with clang 2.9, the same variable is set but empty, implying the default set of analysis. We still want sa_assert defined in that case, to stop clang from hitting false positives. * configure.ac (STATIC_ANALYSIS): Detect clang even when the set of analyses is the default. --- I'm pushing this under the trivial rule. It has no effect on a real build, but makes it easier for me to repeat my clang testing on rawhide. configure.ac | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/configure.ac b/configure.ac index 7c68bca..314a594 100644 --- a/configure.ac +++ b/configure.ac @@ -2297,7 +2297,7 @@ cp -f COPYING.LIB COPYING # Detect when running under the clang static analyzer's scan-build driver # or Coverity-prevent's cov-build.
