Two more improvements for null pointer handling: storing a null pointer
and passing a null pointer into a function.

For this testcase:

void %test(int** %X) {
  store int* null, int** %X
  call void %test(int** null)
  ret void
}

we now generate this:

test:
        sub %ESP, 12
        mov %EAX, DWORD PTR [%ESP + 16]
        mov DWORD PTR [%EAX], 0
        mov DWORD PTR [%ESP], 0
        call test
        add %ESP, 12
        ret

Second half of my fixed-sized-alloca patch.  This folds the LEA to compute
the alloca address into common operations like loads/stores.

In a simple testcase like this (which is just designed to excersize the
alloca A, nothing more):

int %test(int %X, bool %C) {
        %A = alloca int
        store int %X, int* %A
        store int* %A, int** %G
        br bool %C, label %T, label %F
T:
        call int %test(int 1, bool false)
        %V = load int* %A
        ret int %V
F:
        call int %test(int 123, bool true)
        %V2 = load int* %A
        ret int %V2
}

test:
        sub %ESP, 12

Chris Lattner [Thu, 13 May 2004 07:40:27 +0000 (07:40 +0000)]
Substantially improve code generation for address exposed locals (aka fixed
sized allocas in the entry block).  Instead of generating code like this:

entry:
  reg1024 = ESP+1234
... (much later)
  *reg1024 = 17

Generate code that looks like this:
entry:
  (no code generated)
... (much later)
  t = ESP+1234
  *t = 17

The advantage being that we DRAMATICALLY reduce the register pressure for these
silly temporaries (they were all being spilled to the stack, resulting in very
silly code).  This is actually a manual implementation of rematerialization :)

I have a patch to fold the alloca address computation into loads & stores, which
will make this much better still, but just getting this right took way too much time
and I'm sleepy.
