Bug description:
Miscompilation in autovectorized code.
---Steps to Reproduce---
See GCC BZ: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92950
The following testcase abort when being compiled with -O3 -march=z13
on IBM Z:
struct a {
int b;
char c;
};
struct a d = {1, 16};
struct a *e =
int f = 0;
int main() {
struct a g = {0, 0 };
f = 0;
for (; f <= 1; f++) {
g = d;
*e = g;
}
if (d.c != 16)
__builtin_abort();
}
The movv1qi pattern emits halfword load instructions instead of character
loads.
All GCC versions since GCC 5 are affected.
Patches for GCC 8, 9, and 10 have been committed to the gcc.gnu.org branches.
Userspace tool common name: gcc
The userspace tool has the following bit modes: 64
Userspace rpm: various Ubuntu gcc packages

[Group.of.nepali.translators] [Bug 1875092] [NEW] support v5.4 syscalls
Public bug reported: [Impact] * update libssecomp syscalls, for example current seccomp on xenial and up, cannot correctly filter calls for focal armhf chroots on v5.4 kernels, due to new syscalls usage. [Test Case] * Boot v5.4 kernel * Use seccomp to try to resolve new syscall numbers * Rebuild snapd snap against bileto ppa with this change * Test that this rebuild snapd snap, can correctly launch confined python armhf interpreter on arm64 v5.4 kernel (i.e. uc20 raspi arm64 beta image) [Regression Potential] * The issue only impacts when one is running on a newer / hwe kernel, and tries to seccomp filter newer binaries that use new syscalls. No changes are made to any existing syscalls or apis. [Other Info] * Bileto PPA with this change is being prepared with this change. ** Affects: libseccomp (Ubuntu) Importance: Undecided Status: Fix Released ** Affects: libseccomp (Ubuntu Xenial) Importance: Undecided Status: New ** Affects: libseccomp (Ubuntu Bionic) Importance: Undecided Status: New ** Affects: libseccomp (Ubuntu Eoan) Importance: Undecided Status: New ** Also affects: libseccomp (Ubuntu Bionic) Importance: Undecided Status: New ** Also affects: libseccomp (Ubuntu Eoan) Importance: Undecided Status: New ** Also affects: libseccomp (Ubuntu Xenial) Importance: Undecided Status: New ** Changed in: libseccomp (Ubuntu) Status: New => Fix Released -- You received this bug notification because you are a member of नेपाली भाषा समायोजकहरुको समूह, which is subscribed to Xenial.
