eh_frame_hdr section
Product: binutils
Version: 2.38 (HEAD)
Status: UNCONFIRMED
Severity: normal

Hi,
linking with with libcudart_static.a produces an empty eh_frame_hdr section.
Steps to reproduce:
curl -s
https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1604/x86_64/cuda-cudart-dev-11-2_11.2.152-1_amd64.deb
| dpkg --fsys-tarfile - | tar xOf -
./usr/local/cuda-11.2/targets/x86_64-linux/lib/libcudart_static.a >
libcudart_static.a
sha256sum libcudart_static.a
3ca014141258ae33abb175aa88a8282507a04d8a16d8f8dc9340e7831c5831e6
libcudart_static.a
cat > main.c <<EOF
void cudaMalloc();
void main()
{
cudaMalloc();
}
EOF
gcc main.c -fuse-ld=gold libcudart_static.a -ldl -lrt -pthread && readelf -WS
./a.out | grep eh_frame_hdr
[17] .eh_frame_hdr X86_64_UNWIND 00000000000979a4 0979a4 000008 00 A
0 0 4
The section is
011b ffff 9889 fdff
and bytes 2 and 3 are set to elfcpp::DW_EH_PE_omit.
The flag any_unrecognized_eh_frame_sections_ is set due to the true condition
at line
https://sourceware.org/git/?p=binutils-gdb.git;a=blob;f=gold/ehframe.cc;h=8a19b21055924ae17c40f9f7c2ac4e421bf58392;hb=HEAD#l665
Please could some one point if it is an issue in the static lib, a missing
feature in gold linker, or incorrect behavior?
