|
| |
| '''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 <code>cld</code> 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.
