Object code control

Controls where uninitialized global variables are allocated.

Controls whether exception handling is enabled in the module being compiled.

When used with -O2 or higher optimization, inlines glue code that optimizes external function calls in your application.

Generates position-independent code required for use in shared libraries.

Specifies the priority level for the initialization of static objects.

Produces a nonexecutable output file to use as an input file in another ld command call. This file may also contain unresolved symbols.

Indicates that the given list of registers cannot be used during the compilation except as a stack pointer, frame pointer or in some other fixed role.

Specifies the storage type for string literals.

Specifies the storage location for constant values.

Generates runtime type identification (RTTI) information for exception handling and for use by the typeid and dynamic_cast operators.

Strips the symbol table, line number information, and relocation information from the output file.

Saves the command-line options used for compiling a source file, the user's configuration file name and the options specified in the configuration files, the version and level of each compiler component invoked during compilation, and other information to the corresponding object file.

Enables recognition of the __thread storage class specifier, which designates variables that are to be allocated thread-local storage; and specifies the threadlocal storage model to be used.
