This commit makes minor adjustments to __floatdidf and __floatundidf in the AVR backend, which are functions responsible for converting 64-bit signed and unsigned integers to double-precision floating-point numbers. While the immediate impact is small, these tweaks could lead to subtle improvements in accuracy or efficiency for AVR applications that perform extensive floating-point arithmetic. Developers may see minimal changes in code generation or numerical results when targeting AVR with GCC.
