Dan Gohman	81313fd8d1	Fix WriteAsOperand to not emit a leading space character. Adjust its callers to emit a space character before calling it when a space is needed. This fixes several spurious whitespace issues in ScalarEvolution's debug dumps. See the test changes for examples. This also fixes odd space-after-tab indentation in the output for switch statements, and changes calls from being printed like this: call void @foo( i32 %x ) to this: call void @foo(i32 %x) llvm-svn: 56196	2008-09-14 17:21:12 +00:00
Wojciech Matyjewicz	1d2c27b23e	Fix PR2002. Suppose n is the initial value for the induction variable (with step 1) and m is its final value. Then, the correct trip count is SMAX(m,n)-n. Previously, we used SMAX(0,m-n), but m-n may overflow and can't in general be interpreted as signed. Patch by Nick Lewycky. llvm-svn: 47007	2008-02-12 15:09:36 +00:00

for switch statements, and changes calls from being printed like
this:
  call void @foo( i32 %x )
to this:
  call void @foo(i32 %x)

count is SMAX(m,n)-n. Previously, we used SMAX(0,m-n), but m-n may
