Document why attribute access doesn't need the same treatment as fn

smallest_int_mode_for_size may abort when the requested mode is not

The mode attr V_F2DI_CONVERT_BRIDGE converts the floating-point mode
to the widden floating-point by design. But we take (RVVM1HF "RVVM2SI") by
mistake.
This patch would like to fix it by replacing the
(RVVM1HF "RVVM2SI") to (RVVM1HF "RVVM2SF") as design.

After Juzhe's vsetvl fix earlier this week this seems safe to push.
Going to do so later.
I tested on rv64gcv_zvl128b with -minline-strlen and didn't see
regressions apart from zbb-strlen-disabled-2.c which will always
fail with -minline-strlen because it expects -mno-inline-strlen.

here's another fix for the CONTIGUOUS attribute: NULL() should

Subject: [PATCH v2] RISC-V: Add vectorized strcmp and strncmp.
This patch adds vectorized strcmp and strncmp implementations and
tests. Similar to
early-ra's likely_operand_match_p didn't handle relaxed and special
memory constraints, which meant that the pass wasn't able to match
LD1RQ instructions to their constraints, and so backed out of
trying to allocate. This patch fixes that by switching the sense
of the match: does the rtx seem

This test shows that we cannot clear *walk_subtrees in
cp_fold_immediate_r when we're in_immediate_context, because that,
as the comment says, affects cp_fold_r as well. Here we had an

This fixes a regression caused by my previous VM fixes.
Fix regression causing ICE for structs with VLAs [PR 112488]
A previous patch the fixed several ICEs related to size expressions
of VM types (PR c/70418, ...) caused a regression for structs where
a DECL_EXPR is not generated anymore

Hi!
The following testcase is miscompiled because two ubsan instrumentations
run into each other.
The first one is the shift instrumentation. Before the C++ FE calls
it, it wraps the 2 shift arguments with cp_save_expr, so that side-effects
in them aren't

So, one way to fix the LRA issue would be just to use
lra_insn_recog_data_len = index * 3U / 2;
if (lra_insn_recog_data_len <= index)
lra_insn_recog_data_len = index + 1;
basically

In mostly_copy_tree_r yes, but I don't see cp_fold doing anything for
TARGET_EXPRs (like it does for SAVE_EXPRs), so I think

Here is the next version, it feels very close to finished. As before, I

There's a few test cases that still need to be written but more tests
