Summary: This catches malformed mir files which specify alignment as log2 instead of pow2. See https://reviews.llvm.org/D65945 for reference, This is patch is part of a series to introduce an Alignment type. See this thread for context: http://lists.llvm.org/pipermail/llvm-dev/2019-July/133851.html See this patch for the introduction of the type: https://reviews.llvm.org/D64790 Reviewers: courbet Subscribers: MatzeB, qcolombet, dschuff, arsenm, sdardis, nemanjai, jvesely, nhaehnle, hiraditya, kbarton, asb, rbar, johnrusso, simoncook, apazos, sabuasal, niosHD, jrtc27, MaskRay, zzheng, edward-jones, atanasyan, rogfer01, MartinMosbeck, brucehoult, the_o, PkmX, jocewei, jsji, Petar.Avramovic, asbirlea, s.egerton, pzheng, llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D67433 llvm-svn: 371608

|
|
# When the coalescing tries to coalesce `%20 = COPY %18`,
|
|
# %18 has been coalesced all the way up to %15 = ROSBG.
|
|
# ROSBG has tied operands and can be commuted, thus it
|
|
# maybe possible to swap the arguments of ROSBG to coalesce
|
|
# this copy. That's what the coalescer attempts.
|
|
#
|
|
# This used to produce an assertion failure in the coalescer,
|
|
# because this particular coalescing trick is used only on
|
|
# full copy. Therefore we were asserting that all the subranges
|
|
# at the point of the copy had a value number.
|
|
# This is actually not true in that example, because %18 is
|
|
# only partial defined before being fully copied.
