--- Comment #2 from Roger Sayle <roger at nextmovesoftware dot com> ---
Grr... This problem is at (currently just beyond) the limits of my abilities.
The TImode STV pass uses data flow to split conversion opportunities up into
chains, effectively performing live range splitting, as some of uses/defs of a
pseudo register may be in one chain, and other (independent) uses/defs of that
pseudo in another chain. In the case reported in the PR, this results in some
occurences of (reg 90) being converted to V1TImode, and other occurrences
remaining in TImode. Worse, thanks to RTL sharing, calling PUT_MODE on a
register in one chain, implicitly affects the mode of that register in other
chains/insns. I must admit that I'd assumed that either all instances of a
pseudo (like (reg 90)) either get converted or all don't get converted [i.e.
chains ~ pseudos]. Fixing this will require either some form of regno mapping
or unsharing... (or??).
I'll continue investigating, but if anyone can see/knows the correct way to fix
this, please do let me know.

--- Comment #5 from H.J. Lu <hjl.tools at gmail dot com> ---
The original TImode STV pass only converts load and store. When other
operations were added, timode_remove_non_convertible_regs no longer works
correctly. After an instruction is removed from the candidate list, any
instructions which use the associated registers should also be removed
from the candidate list.

commit r13-1811-g76d6224b944e1a66bfb1195fb7d35d9726f1aed8
Author: Roger Sayle <roger@nextmovesoftware.com>
Date: Sun Jul 24 12:22:22 2022 +0100
PR target/106303: Fix TImode STV related failures on x86.
This patch resolves PR target/106303 (and the related PRs 106347,
106404, 106407) which are ICEs caused by my improvements to x86_64's
128-bit TImode to V1TImode Scalar to Vector (STV) pass. My apologies
for the breakage. The issue is that data flow analysis is used to
partition usage of each TImode pseudo into "chains", where each
chain is analyzed and if suitable converted to vector operations.
The problems appears when some chains for a pseudo are converted,
and others aren't as RTL sharing can result in some mode changes
leaking into other instructions that aren't/shouldn't/can't be
converted, which eventually leads to an ICE for mismatched modes.
My first approach to a fix was to unify more of the STV infrastructure,
reasoning that if TImode STV was exhibiting these problems, but DImode
and SImode STV weren't, the issue was likely to be caused/resolved by
these remaining differences. This appeared to fix some but not all of
the reported PRs. A better solution was then proposed by H.J. Lu in
Bugzilla, that we need to iterate the removal of candidates in the
function timode_remove_non_convertible_regs until there are no further
changes. As each chain is removed from consideration, it in turn may
affect whether other insns/chains can safely be converted.
