-compress
Strip the compiled executable to compress it.
-keepc
Specify that you want V to not delete the intermediate generated C source code.
Use with -cg for best debugging experience.
-freestanding
Build the executable without dependency on libc.
Supported only on `linux` targets currently.

Examples:
v hello.v Compile the file `hello.v` and output it as `hello` or `hello.exe`.
v run hello.v Same as above but also run the produced executable immediately after compilation.
v -keepc -cg run hello.v Same as above, but make debugging easier (in case your program crashes).
v -cg run hello.v Same as above, but make debugging easier (in case your program crashes).
v -o h.c hello.v Translate `hello.v` to `h.c`. Do not compile further.
V supports the following commands:

To debug issues in the generated C code, you can pass these flags:
- `-cg` - produces a less optimized executable with more debug information in it.
- `-keepc` - keep the generated C file, so your debugger can also use it.
- `-showcc` - prints the C command that is used to build the program.
For the best debugging experience, you can pass all of them at the same time: `v -cg -keepc -showcc yourprogram.v` , then just run your debugger (gdb/lldb) or IDE on the produced executable `yourprogram`.
For the best debugging experience, you can pass all of them at the same time: `v -cg -showcc yourprogram.v` , then just run your debugger (gdb/lldb) or IDE on the produced executable `yourprogram`.
If you just want to inspect the generated C code, without further compilation, you can also use the `-o` flag (e.g. `-o file.c`). This will make V produce the `file.c` then stop.
