[llvm-commits] Patch: avoid legalization assert

[Mon Ping Wang]

Hi,

In the test case below, we will generate an assert
   "Illegal type introduced after type legalization?"

In this test case, when legalizing the divide operation, we end up  
generating a library call with nodes that needs type legalization.   
This patch avoids the legalize assert if we run LegalizeType and then  
run LegalizeDAG.  This is a stop gap fix because we don't want to do  
any  type legalization to be done in LegalizeDAG. When we legalize an  
operation that generates a call to a library function, maybe we should  
call LegalizeType on the call sequence nodes that were created for the  
call.
