Sylvestre Ledru 522c0ec295 scan-build: Add an option to show the description in the list of defect
Summary:
This patch adds an option //--show-description// to add the defect description to the list of defect. This helps to get a better understanding of the defect without opening the page.

For example, this is used for Firefox:

Yury Gribov a6560ebe4c [analyzer] Add --force-analyze-debug-code option to scan-build
to force debug build and hopefully enable more precise warnings.

Static Analyzer is much more efficient when built in debug mode
(-UNDEBUG) so we advice users to enable it manually. This may be
inconvenient in case of large complex projects (think about Linux
distros e.g. Android or Tizen). This patch adds a flag to scan-build
which inserts -UNDEBUG automatically.

Devin Coughlin 932d88ca05 [analyzer] Fix scan-build to handle missing output directories.
Cwd::abs_path has a somewhat tricky semantics: if it's operand directory does not exist,
it'll return undefined (see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=257568).
This may cause scan-build to silently ignore output directory (specified with -o) and
use /tmp instead of trying to create directory. This tiny patch fixes the problem.

Anton Yartsev 5d381bc775 [analyzer] Make inclusion/exclusion of checkers less ambiguous.
A checker may be enabled/disabled multiple times via -enable-checker and -disable-checker scan-build arguments. Currently the conflicting and repetitive arguments are passed to the analyzer as is.
With this patch only the last enable/disable of a particular checker is accepted and passed to the analyzer.
This change is mostly done for the upcoming 'config for scan-build' patch when multiple inclusions/exclusions of a checker are expected to be more common.

Devin Coughlin 8e850d45e4 [analyzer] ccc-analyzer: Fix -isystem value passing.
The regex for -isystem matching is broken. -[D,I,Usystem] matches "-D", "-,",
"-I", "-U", "-s" "-y", etc. Besides that, "-isystem /foo" gets interpreted as
"-i" with a non-empty value "system" and thus the next "/foo" argument is not
read. This patch corrects the regex.

This fixes PR13237 <https://llvm.org/bugs/show_bug.cgi?id=13237>.

Devin Coughlin 26c5df2c21 [analyzer] scan-build: Teach ccc-analyzer about -Xclang.
Update ccc-analyzer to forward both -Xclang and its following argument to the
the compiler driver. Previously we were dropping -Xclang and forwarding the
argument on its own if it matched other forwarding criteria. This caused the
argument to be interpreted as a driver rather than a frontend option.

Ted Kremenek 0270a08ebf [Static Analyzer] Add --analyzer-target option to scan-build.
When interposing on a compiler doing cross-compilation, scan-build
does not infer the target triple needed to pass to clang for
doing static analysis.  The --analyzer-target option allows one
to manually specify the target triple used during static analysis
(and only static analysis) for such cases.

Sylvestre Ledru f8a5ce35a4 scan-build: Remove useless whitespace in File path
Patch by Honggyu Kim

Summary:
This patch removes useless whitespace in File path in index.html
Previously, a File directory path is copied and pasted as below:
  arch /arm /kernel /stacktrace.c

It just removes the whitespace between directories and makes the
copied string as below:
  arch/arm/kernel/stacktrace.c

The output looks same in html format, but the copied directory path
can be pasted as it looks.
