...ere is any other way to let Clang do so. What I am considering is how to let the generated IR looks like below, which some tools realize: define dso_local i32 @_Z1fPii([51 x i32]* %A, i32 %x) local_unnamed_addr #0 !dbg !7 { entry: ... } Best regards, ------------------------------------------ Tingyuan LIANG MPhil Student Department of Electronic and Computer Engineering The Hong Kong University of Science and Technology ________________________________ From: David Blaikie <dblaikie at gmail.com> Sent: Sunday, June 30, 2019 1:40 PM To: Tingyuan LIANG Cc: llvm-dev at lists.llvm.org Subject:...

...main() function. It seems that the problem is caused by "LoopAccessLegacyAnalysis", since I have not faced this problem with other passes. I am wondering how I can fix this situation.

...should return non-negative range but it seems not so in the example. Is there anything wrong? 2) The range of the IR %rem81 should be [0,3), considering the equation: X%3 < 3?

...eturn 2. However, if I use getCalledFunction()->getNumParams(), it will return 1. According to the IR, I think the number of operands of the call instruction should be 1.
