gcc compiler optimization
compiler optimization - Can't turn off gcc optimizer, Makefile from.
Optimization Levels - GNAT User's Guide - GCC.
Note that many other compilers do fairly extensive optimization even if "no optimization" is specified. When using gcc, it is very unusual to use -O0 for production.
I am doing some numerical optimization on a scientific application. One thing I noticed is that GCC will optimize the call pow(a,2) by compiling it.
In regards to optimizations done by the compiler (GCC), what is the standard practice? What does each option (-O, -O1, -O2, -O3, -Os, -s.

Compiler optimization is generally implemented using a sequence of optimizing transformations, .. GCC is a compiler which exemplifies this approach.

Why doesn't GCC optimize a*a*a*a*a*a to - Stack Overflow.
GCC performs nearly all supported optimizations that do not involve a space- speed tradeoff. The compiler does not perform loop unrolling or function inlining.
I've been given the task to optimize a piece of code but as far as i can. Look at the assembly.
gcc -static myfile.c -L/user/local/math -lmath -o execfile. Compile myfile.c with optimization and link to output file execfile: $ gcc -O myfile.c -o execfile.
In GNU C, you declare certain things about functions called in your program which help the compiler optimize function calls and check your code more carefully.
Apr 12, 2013. The compile time of the GCC C compiler binary with link-time optimization went down by over 10 benchmarked on x86-64 target).
GCC enables this option by default. If you want to force the compiler to check if the variable was referenced, regardless of whether or not optimization is turned.

With GCC and Clang you can use the -fno-elide-constructors compilation flag to turn off copy/move elision optimization.
