I would like to backport the following 4 commits into 12.0.1 release:
The following are 4 commits ordering from latest to earliest in llvm13 trunk:
. 6d102f15a3af0a44cf2e26677e260bee425312f3 BPF: Add LLVMTransformUtils in
CMakefile LINK_COMPONENTS
. 1959ead525b8830cc8a345f45e1c3ef9902d3229 BPF: Implement
TTI.getCmpSelInstrCost() properly
. 74975d35b47631da0c7911561f16d3ffd1af142a BPF: Add LLVMAnalysis in CMakefile
LINK_COMPONENTS
. a260ae716030d5d2644a2af649501277d326bb21 BPF: Implement TTI.IntImmCost()
properly
These 4 patches enabled llvm generating more verifier friendly code for BPF
backend and reduced user's pain to tweak their applications in order to satisfy
verifier.
