New Revision: 249d7de1190f50178181d2477aa661cd252e294c
URL: https://github.com/llvm/llvm-project/commit/249d7de1190f50178181d2477aa661cd252e294c
DIFF: https://github.com/llvm/llvm-project/commit/249d7de1190f50178181d2477aa661cd252e294c.diff
LOG: [RISCV] Don't print zext.b alias.
This alias for andi x, 255 was recently added to the spec. If we
print it, code we output can't be compiled with -fno-integrated-as
unless the GNU assembler is also a version that supports alias.
