Hi all,
This patch aims to fix the cvtps2pd insn, which should also work on
memory operand but currently does not. After this fix, when loop == 2,
it will eliminate movq instruction.
Regtested on x86_64-pc-linux-gnu. Ok for trunk?
BRs,

In libsanitizer code, the size of some GNU libc data structure (notably,
struct stat) is hard coded. These sizes may trigger a static assert
buidling against another libc.
Just make non-GNU libc targets UNSUPPORTED now. If someone really cares
about those alternative libc implementations,
Hi,
We've made a consensus [1] that not to enable trapping for division by
zero by default for LLVM, and we think GCC should behave similarly.
The main rationales:
1. Division by zero is undefined behavior, so in theory any portable
program shall not depend on it.
2. There are already many
Committed to trunk, thanks :)

Hi all,
I just found in MASK_ISA2_UNSET part, since AVX512BW is based on AVX512F, we
should add OPTION_MASK_ISA2_AVX512BW_UNSET to AVX512F for maintainence
convenience and logic correctness, or we will need to add all future ISAs based
on AVX512BW in both AVX512F and AVX512BW. This will be easily

Currently, this is a rather useless patch - even though it helps to reduce
the number of local patches I have. Due to the printed sorry, adding a

Hi,
The variables being used to get the result out of TYPE_VECTOR_SUBPARTS
were being flagged by -Werror=maybe-uninitialized. As they have already
been checked for being constant earlier, use `to_constant' instead.
This patch is based on feedback from Andreas. Given the error they got,
this
In C++03, -Wc++11-compat should warn about
int constexpr;
since 'constexpr' is a keyword in C++11. Jonathan reports that
we don't emit a similar warning for 'alignas' or 'alignof', and,
as I found out, 'thread_local'.
Similarly, we don't warn for most C++20 keywords. That happens
