Hi Jeff,
Sorry for this missing.
I've removed riscv_asm_output_pool_epilogue because the pool beginning is
always aligned from FUNCTION_BOUNDARY.
Please find attached. Thank you.

From: Pan Li
This patch would like to fix one bug of const vector for interleave.
Assume we need to generate interleave const vector like below.
V = {{4, -4, 3, -3, 2, -2, 1, -1,}
Before this patch:
vsetvl a3, zero, e64, m8, ta, ma
vid.v v8v8 = {0, 1, 2, 3, 4}
li a6
The fix is reasonable.
But the test ASM check is too fragile which will easily break in the feature.
The key of the check should be:
vid.v v8 -> can be v0, v8, v16, v24 since LMUL = 8
vadd.vi v8, v8, -4 -> should be using the result of vid.
I think you should adjust test check a
LGTM.

After recent fixes, almost all real FAILs on RV64 full coverage testing are
fixed.
So, it's reasonable to start test RV32 vect testing now.
We will enable full coverage testing RV32 soon and to see what else need to be
fixed.

An alternative approach for the lambda issue would be to modify
'maybe_add_lambda_conv_op' to not pass a null pointer, but I wasn't sure
what the best approach for that would be.
