如何使用scan-build在不同的目标上运行clang静态分析器

Question

我想在不同的目标上运行clang静态分析器。这里是makefile剪辑：

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"$(@)" -o "$@" "$<" 

我想编译为powerpc。这是命令行和输出：

>> <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 

注意的是，虽然makefile文件呼吁铛 - 我得到的gcc警告...所以我怎么使用铛编译代码和针对不同的目标静态分​​析？

找到了解决方案。我认为这是在CCC-分析脚本，在未来PARAM了一个错误：

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 '=' 
); 

的

'-target' => 1, 

需求是

'--target' => 1, 

（双 ' - '）。 ..
