2.1.106 -S
This option instructs the compiler to output the disassembly of the machine code
generated by the compiler to a file.
Unlike the --asm option, object modules are not generated. The name of the assembly
output file defaults to filename.s in the current directory, where filename is the name of
the source file stripped of any leading directory names. The default filename can be
overridden with the -o option.
You can use armasm to assemble the output file and produce object code. The compiler
adds ASSERT directives for command-line options such as AAPCS variants and byte
order to ensure that compatible compiler and assembler options are used when
reassembling the output. You must specify the same AAPCS settings to both the
assembler and the compiler.

2.1.107 --[un]signed_bitfields
This option makes bitfields of type int signed or unsigned.
The C Standard specifies that if the type specifier used in declaring a bitfield is either
int, or a typedef name defined as int, then whether the bitfield is signed or unsigned is
dependent on the implementation.
Default
The default is --unsigned_bitfields.
