Package: qemu-user-static
Version: 1:6.1+dfsg-8
Severity: important
on an amd64 host in in arm64 chroot running under qemu-user-static,
I observed some segmentation fault while building pocl against llvm-13
this is not reproducible on a porter box
it works fine with lli-12
in the arm64 chroot llvm-13 and clang-13 need to be installed
# cat compile_test_6cqj4.c
#ifndef offsetof
#define offsetof(type, member) ((char *) &((type *) 0)->member - (char *) 0)
#endif
typedef double double16 __attribute__((__ext_vector_type__(16)));
int main(int argc, char** argv) {
typedef struct { char x; double16 y; } ac__type_alignof_;
int r = offsetof(ac__type_alignof_, y);
return r;
}
# clang-13 -o try_run.bc -x c -emit-llvm -c --target=aarch64-unknown-linux-gnu
compile_test_6cqj4.c
# lli-13 -force-interpreter try_run.bc ; echo $?
PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash
backtrace.
