Dan Gohman	559254b697	Add -disable-output to a bunch of tests that don't care about the output. ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73633 91177308-0d34-0410-b5e6-96231b3b80d8	2009-06-17 20:56:26 +00:00
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
Wojciech Matyjewicz	7b5b76835a	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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47007 91177308-0d34-0410-b5e6-96231b3b80d8	2008-02-12 15:09:36 +00:00
