how to run clang static analyzer on different target using scan-build - clang

Question

I want to run clang static analyzer on different target. Here is the makefile snip:
CC = <path to clang folder>/build/bin/clang
.
.
.
src/%.o: ../src/%.c
${CC} --target=powerpc -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"$(#:%.o=%.d)" -MT"$(#)" -o "$#" "$<"
I am trying to compile to powerpc. This is the command line and the output:
>> <path_to_llvm_folder>/llvm/tools/clang/tools/scan-build/scan-build --use-analyzer=<path_to_llvm_folder>/build/bin/clang make
scan-build: Using '<path_to_llvm_folder>/build/bin/clang' for static analysis
Building file: ../src/testing.c
Invoking: GCC C Compiler
<path to clang folder>/llvm/tools/clang/tools/scan-build/ccc-analyzer --target=powerpc -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"src/testing.d" -MT"src/testing.o" -o "src/testing.o" "../src/testing.c"
cc1: warning: command line option "-ftarget=powerpc" is valid for Java but not for C
Notice that although the makefile is calling clang - I am getting gcc warning...So how do I use clang to compile the code AND for static analysis for different target ?

Answer 1

found the solution. I think there is a bug in the ccc-analyzer script in the next param:
my %CompilerLinkerOptionMap = (
'-Wwrite-strings' => 0,
'-ftrapv-handler' => 1, # specifically call out separated -f flag
'-mios-simulator-version-min' => 0, # This really has 1 argument, but always has '='
'-isysroot' => 1,
'-arch' => 1,
'-m32' => 0,
'-m64' => 0,
'-stdlib' => 0, # This is really a 1 argument, but always has '='
'--sysroot' => 1,
'-target' => 1,
'-v' => 0,
'-mmacosx-version-min' => 0, # This is really a 1 argument, but always has '='
'-miphoneos-version-min' => 0 # This is really a 1 argument, but always has '='
);
the
'-target' => 1,
needs to be
'--target' => 1,
(with double '-')...
