arm,gcc and dsp instructions

[Victor Librado <vlibrado at bioingenieria dot es>]

Hello all,
I`m working with an arm core 9260EJ-S under Linux (Linux kernel 2.6.15; 
armv5l-linux toolchain with compiler gnu gcc 3.4.2).  I would like to 
take advantage of the asm DSP like functions the core provides. I 
compile this way:

arm-linux-gnu -msoft-float -mtune=arm926ejs -S mul.c

Code generated uses these assembly dsp instructions sometimes (I think 
critical parts should be assembly written), but it exists any kind of 
patch or derivative to "tell" gcc to improve the code generated using 
these kind of 1 cycle instructions more offently?


Thanks in advance.
