[llvm-commits] CVS: llvm/lib/CodeGen/InstrSched/InstrScheduling.cpp

[Brian Gaeke]

Changes in directory llvm/lib/CodeGen/InstrSched:

InstrScheduling.cpp updated: 1.74 -> 1.75

---
Log message:

Convert a few assertions with side-effects into regular old runtime checks.
These side-effects seem to make a difference when using llc -march=sparcv9
in Release mode (i.e., with -DNDEBUG); when they are left out, lots of
instructions just get dropped on the floor, because they never end up
in the schedule.

Diffs of the changes:  (+8 -5)
