GCC Compiler Collection

This release of Fedora has been built with GCC 4.3.2, which is included with the distribution.

For more information on GCC 4.3, refer to:

Target-Specific Improvements

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 -mcld 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 --enable-cld configure option.
