Hi,
I will need to notify you that x_riscv_xventana_subext,
MASK_XVENTANACONDOPS and TARGET_XVENTANACONDOPS are added (I think you
want to rewrite those definitions like the rest). Also, be careful not
to remove TARGET_ZICOND_LIKE.
Thanks,
Tsukasa

Hello,
Many RISC-V builtins operate in signed integer types but in many cases,
they are better to be unsigned.
There are a few reasons to do that:
1. Being more natural
For bit manipulation operations, the direct input and the result should

For bit manipulation operations, inputs and the manipulated output are
better to be unsigned like other target-independent builtins like

Although this is not completely compatible as before (as the type changes),

This commit replaces the type of the builtin used in the testsuite.
Even without this commit, it won't cause any test failures but changed so
that no confusion occurs.

Hi Robin,
Yes, you're right, this should not be necessary. This is more of a
test for the execution environment than the compiler. I think Juzhe
removed it already in his patch that enables the vector test suite.
In the future we would use the checks that Joern added, not sure if
they are alre
Hi,
As discussed in PR111303:
For pattern "(X + C) / N": "div (plus@3 @0 INTEGER_CST@1) INTEGER_CST@2)",
Even if "X" has value-range and "X + C" does not overflow, "@3" may still
be undefined. Like below example:
_3 = _2 + -5;
if (0 != 0)
goto ; [34.00%]
else
goto ; [66.00%]

This patch removes the incorrect earliest poset vsetvl optimization,
such bug was found in vect-double-reduc-5.c which is runtime(execution fail)
and also in PR111313.
For VLMAX intrinsics, we always emit a bogus patter which is vlmax_avl (see
vector.md) to
occupy a scalar register which is used

For LoongArch, the toplevel library build is always aliased to
one of the multilib variants. This patch installs it with the
actual MULTISUBDIR (instead of ".") so that the headers can be
reached by the compiler.
