Summary: Optimization introduces intrinsics and they are not
lowered.
Product: libraries
Version: trunk
Platform: PC
OS/Version: All
Status: NEW
Severity: normal
Priority: P
Component: Common Code Generator Code
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
Starting with the attached file, execute this sequence of operations:
llvm-as code.llvm -o code.bc
opt -O2 code.bc -o code.opt.bc
llvm-dis code.opt.bc -o code.opt.llvm
code.opt.llvm contains a call to llvm.trap, which was not present on the
original code. I have more instances where intrinsics are introduced by
otpimization (not only llvm.trap).
