# Kernel bitcodes generated:
# * <triple>-sm30-ptx60lt
# * Includes subgroup shuffles.
# * Excludes subgroup ballot (see details in subgroup_ballot.cl).
# * Intended for targeting 3.0 <= SM <= 7.5.
# * <triple>-sm30-ptx60-63:
# * Includes subgroup ballot and shuffles.
# * Targeted for PTX 6.0 - 6.3. This library uses intrinsics that work
# for both the LLVM and PTX assembler.
# * Intended for targeting 3.0 <= SM <= 7.5.
# * <triple>-sm70-ptx64: Supports ballot and shfl
# * Excludes subgroup shuffles or ballot. The support would require
# use of .sync variants.
# * Inteded for targeting SM >=7.0.
