--- Comment #20 from Kito Cheng <kito at gcc dot gnu.org> --- Created attachment 47972 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=47972&action=edit PR90811-ipa-increase-alignment.patch Hi Jeff: Updated patch attached, tested on riscv32/riscv64, this version take the suggestion from Andrew, implement that in ipa_increase_alignment pass, I saw the dump file number is 67, but ompdevlow is 92, I am not sure it's late enough or not, since I failed to reproduce the original issue on x86_64 + nvptx + cuda 10.0, I just get some error message seems like unrelated to this alignment issue even with r272181. as /tmp/ccuQhrDr.s, line 26; error : Arguments mismatch for instruction 'mov' as /tmp/ccuQhrDr.s, line 91; error : Arguments mismatch for instruction 'mov' as /tmp/ccuQhrDr.s, line 98; error : Label expected for argument 0 of instruction 'call' as /tmp/ccuQhrDr.s, line 98; fatal : Call target not recognized * Note, as has replaced to ptxas manually, it was https://github.com/MentorEmbedded/nvptx-tools Did you mind tell me how to build the environment to reproduce? My current configure option and version: GCC version g:6b3302da9ef26aa11940f8c0dc92bec19e15c09b CUDA: 10.0 (8.0 install failed on Ubuntu 18.04) x86_64: --disable-bootstrap --disable-multilib --enable-languages=c,c++,lto,fortran --enable-offload-targets=nvptx-none --enable-multiarch --with-cuda-driver=/usr/local/cuda nvptx-none nvptx: --disable-bootstrap --disable-sjlj-exceptions --enable-newlib-io-long-long --target=nvptx-none --enable-as-accelerator-for=x86_64-linux-gnu --enable-languages=c,c++,fortran,lto --program-prefix=nvptx-none- Thanks
