Because neither ' ' nor '-' is alphanumeric, \b won't match between them!
Since in this case we know our output is coming from a -### invocation,
we should always have spaces on both sides of the flag we're trying to match,
"-cc1".

More universal way of removing trailing whitespace characters then 'chomp' does. Chomp "removes any trailing string that corresponds to the current value of $/" (quote from perldoc). In my case an input ended with '\r\r\n', chomp left '\r' at the end of input and the script ended up with an error "Use of uninitialized value in concatenation (.) or string"

Some of the shared compiler/linker flags start with -m, so they've been
getting passed to the compiler only since r180073. Now, the -m* wildcard
is processed after the shared flags and the ignored flags.

These flags control language options and user-visible macros, so it's
important to preserve them when analyzing. Rather than try to keep up
with all the -f flags, we'll pass them all through and then ban the ones
we don't want (like -fsyntax-only).
-Wwrite-strings is really an f-flag in disguise: it implies -fconst-strings.

This is important for preprocessing steps, which may output to stdout.
Also, change ENV accesses using barewords to use string keys instead.

This is how Xcode lets individual files be marked as non-ARC when the rest
of the project is ARC-enabled, so this is necessary for scan-build xcodebuild.

Load custom plugins when running scan-build. This is useful when
additional static analysis Checkers must be provided via clang's plugin
interface.
Loading additional plugins can now be done via the scan-build call:
scan-build -load-plugin <plugin.so>

scan-build ignores clang failures in some cases, which might lead to
silent failure suppression. For example, if clang command line
argument is wrong. (Addresses radar://10406598)

(scan-build does not set the $HtmlDir when running against configure. Previously, this implied that the plist files would appear in the current directory, with this patch they will get deleted.)
llvm-svn: 139382
We now rely on 'clang --analyze' to provide the default set of checkers. We're
still working on the new '-analyzer-checker <checker>' interface, and once
that's ready we'll wire it up to scan-build.

accidentally using it without realizing that it is nowhere close
to being generally usable and are reporting crashes that we
already know about.
