-//*****************************************************************************
-// aeabi_romdiv_patch.s
-//  - Provides "patch" versions of the aeabi integer divide functions to
-//    replace the standard ones pulled in from the C library, which vector
-//    integer divides onto the rom division functions contained in
-//    specific NXP MCUs such as LPC11Uxx and LPC12xx.
-//  - Note that this patching will only occur if "__USE_ROMDIVIDE" is
-//    defined for the project build for both the compiler and assembler.

-// Note that the romdivide "divmod" functions are not actually called from
-// the below code, as these functions are actually just wrappers to the
-// main romdivide "div" functions which push the quotient and remainder onto
-// the stack, so as to be compatible with the way that C returns structures.
-//
-// This is not needed for the aeabi "divmod" functions, as the compiler
-// automatically generates code that handles the return values being passed
-// back in registers when it generates inline calls to __aeabi_idivmod and
-// __aeabi_uidivmod routines.
