[fpc-devel] Re: Faster Implementation for IntToStr

BTW, I found only one caveat in that asm-implementation: according to Intel docs
target register of BSR is "undefined" if source=0, so Z-flag should always
be checked after BSF/BSR.

In case of "int_str" ECX randomisation after BSR surely will lead to crash,
but in practice I can not reproduce such spurious behavior.
