From Issue #131March 2005
GCC Home page: gcc.gnu.org
Using the GNU Compiler Collection (GCC): gcc.gnu.org/onlinedocs/gcc-3.2.2/gcc
The article states that -O is equivalent to -O0 (no optimization). The manual says -O0 and no "-O" option at all are the same, and -O is equivalent to -O1.
I am using -O with programs that require inline (using in and out macros), and I get inline function expansions for those and for memcpy etc., but the manual says the inline-functions optimization is only done with -O3. Is this an error in the manual?
Where are the source files from your article. I am specifically interested in your timing calls. TIA
