Hi!
When debugging PR112750, I've noticed some issues in the computation
of precisions and the following patch attempts to fix those.
The pass uses range_to_prec function, which possibly using ranger returns
minimum precision of some operand in the style that libgcc _BitInt
entrypoints expect,

From: Pan Li
If we want to extract 64bit value but ELEN < 64, we use RVV
vector mode with EEW = 32 to extract the highpart and lowpart.
However, this approach doesn't honor DFmode when movdf pattern
when ZVE32f and of course results in ICE when zve32f.
This patch would like to reuse the

I think you should make sure to not use VLA vectors in lowering since lowering
doesn't really support using those (much similar to BB SLP).

Besides, the mask type is:
vector([4,4])

After reproducing the ICE.
I confirm the root cause is because we enable vec_extract for mask:
;; -
;; This extracts a bit (via QImode)

--- Comment #3 from JuzheZhong ---
I see. I didn't reproduce the ICE since I didn't enable gcc_assert_checking.
Could you tell me how to enable it ?
I hack the codes as follows:
diff --git a/gcc/poly-int.h b/gcc/poly-int.h
index

Yes.

Sounds great!
It'd be

Hi, Robin.
Thanks for working on this. I know this is a tedious work.
A couple comments here:
- if (TARGET_ZBB || TARGET_XTHEADBB)
+ if (TARGET_VECTOR && stringop_strategy & STRINGOP_STRATEGY_VECTOR)

This patch fix 2 regression (one is bug regression, the other is performance
regression).
Those 2 regressions are both we are comparing ratio for same AVL in wrong place.
1. BUG regression:
avl_single-84.c:
f0:
li a5,999424
add a1,a1,a5
li a4,299008

Hi,
this adds vectorized implementations of strcmp and strncmp as well as
strlen. strlen falls back to the previously implemented rawmemchr.
Also, it fixes a rawmemchr bug causing a SPEC2017 execution failure:
We would only ever increment the source
