[PATCH] D88525: BPF: use Source instead of ILP scheduler for selection dag

[Yonghong Song via Phabricator via llvm-commits]

yonghong-song updated this revision to Diff 295182.
yonghong-song retitled this revision from "[RFC] BPF: use Source instead of ILP scheduler for selection dag" to "BPF: use Source instead of ILP scheduler for selection dag".
yonghong-song edited the summary of this revision.
yonghong-song added a comment.

removed RFC tag as bpf selftests are solved.
using setSchedulingPreference() instead of enableMachineScheduler() to limit the scope
Regarding previous reported failures for bpf selftest test_verif_scale3.o:

- current llvm-project master: processed 997315 insns
- enableMachineScheduler() processed 1005967 insns (hacked verifier to increase to permit 2M insns), resulted from more instructions due to enabled machine scheduling phase (and possibly additional regalloc functionality, not verified).
- setSchedulingPreference() processed 998991 insns
