[LLVMdev] PHI and Allocas
...ompiler to account for variable mutations
around if/else blocks.
Reading the Kaleidoscope tutorial, I've learnt that I can substitute
the PHI node creation by allocas and retrieving the value later, if
needed. The Kaleidoscope example seems to account for one value only,
the result of:
Value *ThenV = Then->Codegen();
(...)
Value *ElseV = Else->Codegen();
(...)
PN->addIncoming(ThenV, ThenBB);
PN->addIncoming(ElseV, ElseBB);
But both Then and Else are expressions, so the Value returned is in
the form of a single variable.
ExprAST *Then = ParseExpression();
(...)
