Use analyzer at new location: prebuilts/misc/{linux-x86,darwin-x86}/analyzer
Analyzer needed by WITH_STATIC_ANALYZER and WITH_SYNTAX_CHECK is
moved from prebuilts/clang/{linux-x86,darwin-x86}/host/3.3 to
prebuilts/misc/{linux-x86,darwin-x86}/analyzer
See https://android-review.googlesource.com/#/c/83852/
BUG=13243591
Usage:
"WITH_SYNTAX_CHECK=1 make ..." instructs build system to invoke "clang -fsyntax-only"
to utilize clang's better diagnostics before calling LOCAL_CC/LOCAL_CXX for code generation.
The compilation time is slightly longer, and the generated object file should be the same as
w/o WITH_SYNTAX_CHECK
"WITH_STATIC_ANALYZER=1 m/mm/mmm/mma/mmma ..." instructs build system to run static
analyzer via "clang --analyze" on a successful build. If analyzer finds any issue, instruction
to open report is displayed. See http://clang-analyzer.llvm.org/scan-build.html for details.
WITH_STATIC_ANALYZER trumps WITH_SYNTAX_CHECK if both exist. Project use lots of GCC extensions
(eg. nested function) not supported by clang may opt out by adding LOCAL_NO_STATIC_ANALYZER:=true
