== Target-Specific Improvements ==
 
=== IA-32/x86-64 ===
 
'''ABI changes'''
 
* Starting with GCC 4.3.1, decimal floating point variables are aligned to their natural boundaries when they are passed on the stack for i386.
 
'''Command-line changes'''
 
* Starting with GCC 4.3.1, the <code>-mcld</code> option has been added to automatically generate a cld instruction in the prologue of functions that use string instructions. This option is used for backward compatibility on some operating systems and can be enabled by default for 32-bit x86 targets by configuring GCC with the <code>--enable-cld</code> configure option.
