Hi,
I have the following queries:
1) Apart from general optimizations (enabled by -O3
flag), what is the total list of optimizations done by
gcc(GNU C compiler) for Pentium-4 processor?
ie)processor specific optimizations only
Can any one tell any source where I can find them?
2)Where can I find list of functions and data types
defined to exploit SIMD features of Pentium-4
processor by GCC. (I am familiar with SIMD features
of Pentium-4.)
3) Pentium-4 has special instructions like MOVNTQ,
MOVNTPS ...to enable data from XMM and MMX registers
to be stored to memory using a non-temporal hint.
How to do the same in a C language?
Can any one help me?
Thanks.
