[Bug 2061845] [NEW] aarch64-linux-gnu-g++-14 package is somewhat old vs g++-14 so can't test new SVE support in std::experimental::simd
Public bug reported: Hi, wanting to test new std::experimental::simd SVE1/2 support in GCC-14 that was committed on 27 march, unfortunately current "aarch64-linux-gnu-g++-14 -v" shows : gcc version 14.0.1 20240121 (experimental) [master r14-8314-g29f931e39f2] (Ubuntu 14-20240121-1ubuntu1) so also is not update vs current x86 gcc-14.. ** Affects: gcc-14 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2061845 Title: aarch64-linux-gnu-g++-14 package is somewhat old vs g++-14 so can't test new SVE support in std::experimental::simd To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gcc-14/+bug/2061845/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 2060619] [NEW] gcc-14 offload support for amd gfx103x and gfx110x gpus is broken
Public bug reported:
Hi,
for context bug was posted here first:
https://github.com/gcc-mirror/gcc/commit/1bf18629c54adf4893c8db5227a36e1952ee69a3#commitcomment-140648051
gcc Andrew Stubbs author mentions:
"Yes, it looks like the libgomp device-side library is missing. Probably not
listed in the packaging script?"
using gcc-14:
gcc-14 --version
gcc-14 (Ubuntu 14-20240330-1ubuntu2) 14.0.1 20240330 (experimental) [master
r14-9728-g6fc84f680d0]
using the code posted below as sum.c
testing building with offload support on gfx1036:
gcc-14 -fopenmp -foffload=amdgcn-amdhsa -foffload-options=-march=gfx1036
-fcf-protection=none sum.c -o sumamd1030.exe
fails with:
ld: error: incompatible mach:
/usr/lib/gcc/x86_64-linux-gnu/14/accel/amdgcn-amdhsa/libgomp.a(parallel.o)
collect2: error: ld returned 1 exit status
gcn mkoffload: fatal error: x86_64-linux-gnu-accel-amdgcn-amdhsa-gcc-14
returned 1 exit status
compilation terminated.
lto-wrapper: fatal error:
/usr/libexec/gcc/x86_64-linux-gnu/14//accel/amdgcn-amdhsa/mkoffload returned 1
exit status
compilation terminated.
/usr/bin/ld: error: lto-wrapper failed
collect2: error: ld returned 1 exit status
instead selecting gfx900 works:
gcc-14 -fopenmp -foffload=amdgcn-amdhsa -foffload-options=-march=gfx900
-fcf-protection=none sum.c -o sumamd900.exe
note gfx103x and gfx11xx targets are new to GCC-14..
inspecting files seems the error is due to package
gcc-14-offload-amdgcn_14-20240330-1ubuntu2_amd64.deb
missing libgomp.so files in
\usr\lib\gcc\x86_64-linux-gnu\14\accel\amdgcn-amdhsa\gfx1036 folder
but having this file in gfx9xx folders for ex:
\usr\lib\gcc\x86_64-linux-gnu\14\accel\amdgcn-amdhsa\gfx906 folder
code used:
sum.c:
#include
#include
#include
#include
int main(int argc, char *argv[]) {
long long int j, largeN;
double sum = 0.0;
clock_t tstart, tend;
int num_dev;
num_dev = omp_get_num_devices();
printf("%d\n", num_dev);
largeN = (long long int) atoll(argv[1]);
printf("Large Number = %lld\n", largeN);
tstart = clock();
#pragma omp parallel for private(j) reduction(+:sum)
