Implement folding explicit load instructions into binary operations. For a
...
testcase like this:
int %test(int* %P, int %A) {
%Pv = load int* %P
%B = add int %A, %Pv
ret int %B
}
We now generate:
test:
mov %ECX, DWORD PTR [%ESP + 4]
mov %EAX, DWORD PTR [%ESP + 8]
add %EAX, DWORD PTR [%ECX]
ret
Instead of:
test:
mov %EAX, DWORD PTR [%ESP + 4]
mov %ECX, DWORD PTR [%ESP + 8]
mov %EAX, DWORD PTR [%EAX]
add %EAX, %ECX
ret
... saving one instruction, and often a register. Note that there are a lot
of other instructions that could use this, but they aren't handled. I'm not
really interested in adding them, but mul/div and all of the FP instructions
could be supported as well if someone wanted to add them.

Implement ArgumentPromotion/aggregate-promote.ll
...
This allows pointers to aggregate objects, whose elements are only read, to
be promoted and passed in by element instead of by reference. This can
enable a LOT of subsequent optimizations in the caller function.
It's worth pointing out that this stuff happens a LOT of C++ programs, because
objects in templates are generally passed around by reference. When these
templates are instantiated on small aggregate or scalar types, however, it is
more efficient to pass them in by value than by reference.
This transformation triggers most on C++ codes (e.g. 334 times on eon), but
does happen on C codes as well. For example, on mesa it triggers 72 times,
and on gcc it triggers 35 times. this is amazingly good considering that
we are using 'basicaa' so far.
