Upon writing my register allocation algorithm, I am concerned that a load may be skipped due to a branch. For instance consider the psudocode int x = 1 ... if( false ) load x y = 3*x else y = 4*x ...

Do I need to be concerned about cases like th...

They cannot be found like the live in values because different values may be live out. For instance the psudocode may look like: BB0: vreg1 = rand() if( vreg1 > .5 ) goto BB1; else goto BB2; BB1: vreg 2 = rand(); EAX = copy vreg2; Return BB2: vreg 3 = rand() * rand()' EAX = copy vreg3; Return On Fri, Nov 5, 2010 at 7:41 AM, s Last namerc <srcsrc84 at yahoo.com> wrote: > Is...
