Page 1 of 1
With each incremental GCC release, there always seems to be more speed and stability fixes and that looks to be the case with GCC 4.6 as well.
There are a number of link-time optimization improvements including memory usage and intermediate language streaming performance improvements.
"A new general optimization level,Going a step further datastructures used by the dataflow framework in GCC were reorganized which results in improved compile time.
-Ofast, has been introduced," the GCC 4.6 release notes state. "It combines the existing optimization level
-O3with options that can affect standards compliance but result in better optimized code. For example,
According to the GCC 4.6 release notes, the compile time of the GCC C compiler binary with link-time optimization went down by over 10 percent.
