Anton Yartsev 39323f95cc [analyzer] Perl scripts are run differently from makefiles. Sometimes additional utilities are involved, e.g. 'env' utility that present in MSYS but is missing in MinGW. The patch unifies launch of "c++-analyzer" and "ccc-analyzer".

Sylvestre Ledru 9e0752980c Fix a bug when scan-build is used in a cross-compilation environment with
the --use-cc option.

Instead, we will search in the PATH
For example:
 scan-build --use-cc=arm-none-eabi-gcc -o out make -e

Sylvestre Ledru c7bc52596f Check that the directory does not exist.
Otherwise, it could allows local users to obtain sensitive information or
overwrite arbitrary files via a symlink attack on temporary directories with
predictable names.

Jordan Rose 428f2e980a [analyzer] scan-build: match whitespace instead of word boundaries around flags.
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".

Anton Yartsev 0cb7c8abc1 [analyzer] Strip trailing whitespace characters from input.
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"

Jordan Rose 476bbb0252 [analyzer] scan-build: Handle -m* option wildcard after compiler/linker flags.
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.

Jordan Rose e10c859583 [analyzer] Put more uniqueness in scan-build's temporary directory names.
This is necessary when running two scan-build processes in parallel. The
directory naming scheme is now:

  yyyy-MM-dd-HHmmss-PID-N
  2013-09-13-174210-123-1

where "PID" is the scan-build process ID, and "N" is a sequential counter
(not likely to be needed now that seconds are mangled in, but just in case).

Jordan Rose 05b3a8b604 [scan-build] Pass through all -f and -O flags, along with -Wwrite-strings.
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.

Jordan Rose d8fb478b36 scan-build: use the xcodebuild specified by the user.
This is important if the user has multiple Xcodes installed on their

The patch allows Windows users to launch scan-build without any additional preparations in the same way as it described in http://clang-analyzer.llvm.org/scan-build.html.
