Switch from EXPECT_EQ({true,false, ...) to the more canonical
EXPECT_{TRUE,FALSE}(...) macros. This also prevents suprious warnings about
bool-to-pointer conversion that occurs withit EXPECT_EQ.

14 years agoHandle the case of a tail recursion in which the tail call is followed
Duncan Sands [Tue, 13 Jul 2010 15:41:41 +0000 (15:41 +0000)]
Handle the case of a tail recursion in which the tail call is followed
by a return that returns a constant, while elsewhere in the function
another return instruction returns a different constant.  This is a
special case of accumulator recursion, so just generalize the existing
logic a bit.

14 years agorotate CallInst operands
Gabor Greif [Tue, 13 Jul 2010 15:31:36 +0000 (15:31 +0000)]
rotate CallInst operands

with this commit the callee moves to the end of
the operand array (from the start) and the call
arguments now start at index 0 (formerly 1)

this ordering is now consistent with InvokeInst

this commit only flips the switch,
functionally it is equivalent to
r101465

I intend to commit several cleanups after a few
days of soak period
