It appears that our embedded ARM7 application is spending a significant amount of time is being spent inside memcpy. I've tried everything I can think of to get gcc to use builtin memcpy code, but it just won't. I've tried various values of -O, I've added -fbuiltin, I've even tried explictly calling __builtin_memcpy(). Nothing works. No matter what I do, gcc just loads up the parameters and makes a call to memcpy(). Does the ARM back end not know how to do a built-in memcpy? $ arm-elf-gcc -v Reading specs from /usr/local/lib/gcc-lib/arm-elf/2.95.2/specs gcc version 2.95.2 19991024 (release) -- Grant Edwards grante@visi.com ------ Want more information?
