Hello All the gurus, I've been fiddling my luck with gcc 4.3.2 inline assembly on powerpc There are a few queries
1. asm volatile or simply asm produce the same assembly code. Tried with a few examples but didnt find any difference by adding volatile with asm 2. Use of "memory" and clobbered registers. "memory" - a. announce to the compiler that the memory has been modified b. this instruction writes to some memory (other than a listed output) and GCC shouldn’t cache memory values in registers across this asm. I tried with stw and stwcx instruction, adding "memory" has no effect. Is there any example scenerio where gcc would generate different assembly by adding / removing "memory" ? -TZ
