Hi Mikael,
The fix is blindingly obvious :-) Not only that, the failing testcase runs
correctly.
OK for mainline and please backport to 14-branch before the 14.2 release.
Thanks for the patch

Regarding shortening it: no need to duplicate what's in the git commit

Heads-up to xtensa maintainers, who might similarly want to move the
option-override to TARGET_OVERRIDE_OPTIONS_AFTER_CHANGE (and call it
from TARGET_OPTION_OVERRIDE).
Regarding disabling that optimization: with the brief description per

When transforming multiple lane-reducing operations in a loop reduction chain,
originally, corresponding vectorized statements are generated into def-use
cycles starting from 0. The def-use cycle with smaller index, would contain
more statements, which means more instruction dependency. For example
For lane-reducing operation(dot-prod/widen-sum/sad) in loop reduction, current
vectorizer could only handle the pattern if the reduction chain does not
contain other operation, no matter the other is normal or lane-reducing.
This patches removes some constraints in reduction analysis to allow mult
Vector stmts number of an operation is calculated based on output vectype.
This is over-estimated for lane-reducing operation, which would cause vector

In g:44fc801e97a8dc626a4806ff4124439003420b20 I'd extended
insn_propagation to handle simple cases of hard-reg mode punning.
One of the checks was that the new use mode occupied the same
number of registers as the original definition mode. However,
as PR115901 shows, we need to avoid increasing th
The asm in the testcase has a memory operand and also clobbers ax.
The clobber means that ax cannot be used to hold inputs, which
extends to the address of the memory.
I think I had an implicit assumption that constrain_operands
would enforce this, but in hindsight, that clearly wasn't going

Hi All,
After messing around with argument mapping, where I found and fixed another
bug, I realised that the problem lay with simplification of len_trim with
an argument that is the element of a parameter array. The fix was then a
straightforward lift of existing code in expr.cc. The mapping bug i

Hi,
According to the instruction spec of AVX512BF16, the convert from float
to BF16 is not a simple truncation. It has special handling for
denormal/nan, even for normal float it will add an extra bias according
to the least significant bit for bf number. This means we cannot use the
