[llvm-bugs] [Bug 44754] New: [InstCombine] ashr+and+icmp not simplified
https://bugs.llvm.org/show_bug.cgi?id=44754
Bug ID: 44754
Summary: [InstCombine] ashr+and+icmp not simplified
Product: libraries
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Scalar Optimizations
Assignee: unassignedb...@nondot.org
Reporter: nikita@gmail.com
CC: llvm-bugs@lists.llvm.org
define i1 @foo(i32 %a) {
%ashr = ashr i32 %a, 5
%and = and i32 %ashr, -2
%cmp = icmp slt i32 %and, 1
ret i1 %cmp
}
is not simplified to
define i1 @foo(i32 %a) {
%and2 = and i32 %a, -64
%cmp = icmp slt i32 %and2, 32
ret i1 %cmp
}
but could be (https://rise4fun.com/Alive/FkZq).
Encountered this as fallout from a worklist order change in
test/Transforms/InstCombine/pr17827.ll.
