Usage: arm-linux-androideabi-gcc [options] file...
Options:
-pass-exit-codes Exit with highest error code from a phase
--help Display this information
--target-help Display target specific command line options
--help={common|optimizers|params|target|warnings|[^]{joined|separate|undocumented}}[,...]
Display specific types of command line options
(Use '-v --help' to display command line options of sub-processes)
--version Display compiler version information
-dumpspecs Display all of the built in spec strings
-dumpversion Display the version of the compiler
-dumpmachine Display the compiler's target processor 计算机的目标处理器
-print-search-dirs Display the directories in the compiler's search path 在计算机中的搜寻路径
-print-libgcc-file-name Display the name of the compiler's companion library 计算机的同伴？指南库的名字？？？
-print-file-name= Display the full path to library
-print-prog-name= Display the full path to compiler component
-print-multiarch Display the target's normalized GNU triplet, used as
a component in the library path
-print-multi-directory Display the root directory for versions of libgcc
-print-multi-lib Display the mapping between command line options and
multiple library search directories
-print-multi-os-directory Display the relative path to OS libraries
-print-sysroot Display the target libraries directory
-print-sysroot-headers-suffix Display the sysroot suffix used to find headers
-Wa, Pass comma-separated on to the assembler 汇编器 a
-Wp, Pass comma-separated on to the preprocessor 预处理器p
-Wl, Pass comma-separated on to thelinker l是连接器，传递选项给连接器
-Xassembler Pass on to the assembler
-Xpreprocessor Pass on to the preprocessor
-Xlinker Pass on to the linker 传递参数给连接器
-save-temps Do not delete intermediate files
-save-temps= Do not delete intermediate files
-no-canonical-prefixes Do not canonicalize paths when building relative
prefixes to other gcc components
-pipe Use pipes rather than intermediate files
-time Time the execution of each subprocess
-specs= Override built-in specs with the contents of
-std= Assume that the input sources are for
--sysroot= Use as the root directory for headers
and libraries
-B Add to the compiler's search paths 这个很好啊给编译器的搜寻路径添加路径
-v Display the programs invoked by the compiler
-### Like -v but options quoted and commands not executed
-E Preprocess only; do not compile, assemble or link -E仅仅需要预编译，但是不要编译、汇编或者链接。
-S Compile only; do not assemble or link -S只是编译，不要汇编或者链接
-c Compile and assemble, but do not link -c编译编译并且汇编，但是不要链接
-o Place the output into
-pie Create a position independent executable -pie创建一个位置无关的可执行程序
-shared Create a shared library 创建一个共享库
-x Specify the language of the following input files
Permissible languages include: c c++ assembler none
'none' means revert to the default behavior of
guessing the language based on the file's extension

Options starting with -g, -f, -m, -O, -W, or --param are automatically
passed on to the various sub-processes invoked by arm-linux-androideabi-gcc. In order to pass
other options on to these processes the -W options must be used.
