[LLVMdev] global register allocation.

[Fernando Magno Quintao Pereira]

Hi, Sanjiv,

     those passes operate on the whole machine function. Each machine 
function contains many basic blocks. If a program has many functions, the 
register allocator will be called as many times, i.e it does not do 
interprocedural allocation.

best,

Fernando
