Compiler Command-line Options
Usage
Use the option --export_defs_implicitly to export definitions where the prototype is
marked __declspec(dllimport).

2.1.68 --extended_initializers, --no_extended_initializers
These options enable and disable the use of extended constant initializers even when
compiling with --strict or --strict_warnings.
When certain non-portable but widely supported constant initializers such as the cast of
an address to an integral type are used, --extended_initializers causes the compiler to
produce the same general warning concerning constant initializers that it normally
produces in nonstrict mode, rather than specific errors stating that the expression must
have a constant value or have arithmetic type.
Default
The default is --no_extended_initializers when compiling with --strict or
--strict_warnings.
The default is --extended_initializers when compiling in non-strict mode.

2.1.69 --feedback=filename
This option enables the efficient elimination of unused functions, and on ARMv4T
architectures, enables reduction of compilation required for interworking.
Syntax
--feedback=filename
Where:
filename
is the feedback file created by a previous execution of the ARM linker.
