从 build 转储二进制文件的反汇编。
usage: fx dis [-l | -S | -n | -L | -P <path to objdump>] BINARY...
Dump disassembly for a binary to a file in the build directory.
-l list source locations interleaved with assembly
-S list source code lines interleaved with assembly
-r list relocations interleaved with assembly
-n do not demangle symbol names
-L use llvm-objdump rather than GNU objdump
-P <path> use objdump binary in argument
Each BINARY can be the name of the binary file without directory, e.g.
"libzircon.so" or "zircon.elf"; or the name of a GN target, e.g. "zircon";
or a string of (lowercase) hex characters that's an ELF build ID.
The disassembly will be written to a file next to the binary file in
the build directory, using its name with ".lst" suffix.
