Dan Gohman	0bddac16a8	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. llvm-svn: 65382	2009-02-24 18:55:53 +00:00
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
Eli Friedman	4736916aa6	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. llvm-svn: 54194	2008-07-30 04:36:32 +00:00
