Dan Gohman	46bdfb0e6b	Rename ScalarEvolution's getIterationCount to getBackedgeTakenCount, ... to more accurately describe what it does. Expand its doxygen comment to describe what the backedge-taken count is and how it differs from the actual iteration count of the loop. Adjust names and comments in associated code accordingly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65382 91177308-0d34-0410-b5e6-96231b3b80d8	2009-02-24 18:55:53 +00:00
Dan Gohman	8dae138d06	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) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56196 91177308-0d34-0410-b5e6-96231b3b80d8	2008-09-14 17:21:12 +00:00
Eli Friedman	1fbffe0cef	Another SCEV issue from PR2607; essentially the same issue, but this ... time applying to the implicit comparison in smin expressions. The correct way to transform an inequality into the opposite inequality, either signed or unsigned, is with a not expression. I looked through the SCEV code, and I don't think there are any more occurrences of this issue. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54194 91177308-0d34-0410-b5e6-96231b3b80d8	2008-07-30 04:36:32 +00:00
