--- Comment #8 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Prathamesh Kulkarni <prathamesh3...@gcc.gnu.org>: https://gcc.gnu.org/g:38900247f3880d6eca2e364a000e5898f8deae64 commit r15-2801-g38900247f3880d6eca2e364a000e5898f8deae64 Author: Prathamesh Kulkarni <prathame...@nvidia.com> Date: Wed Aug 7 23:45:38 2024 +0530 Partially support streaming of poly_int for offloading. When offloading is enabled, the patch streams out host NUM_POLY_INT_COEFFS, and changes streaming in as follows: if (host_num_poly_int_coeffs <= NUM_POLY_INT_COEFFS) { for (i = 0; i < host_num_poly_int_coeffs; i++) poly_int.coeffs[i] = stream_in coeff; for (; i < NUM_POLY_INT_COEFFS; i++) poly_int.coeffs[i] = 0; } else { for (i = 0; i < NUM_POLY_INT_COEFFS; i++) poly_int.coeffs[i] = stream_in coeff; /* Ensure that degree of poly_int <= accel NUM_POLY_INT_COEFFS. */ for (; i < host_num_poly_int_coeffs; i++) { val = stream_in coeff; if (val != 0) error (); } } gcc/ChangeLog: PR ipa/96265 PR ipa/111937 * data-streamer-in.cc (streamer_read_poly_uint64): Remove code for streaming, and call poly_int_read_common instead. (streamer_read_poly_int64): Likewise. * data-streamer.cc (host_num_poly_int_coeffs): Conditionally define new variable if ACCEL_COMPILER is defined. * data-streamer.h (host_num_poly_int_coeffs): Declare. (poly_int_read_common): New function template. (bp_unpack_poly_value): Remove code for streaming and call poly_int_read_common instead. * lto-streamer-in.cc (lto_input_mode_table): Stream-in host NUM_POLY_INT_COEFFS into host_num_poly_int_coeffs if ACCEL_COMPILER is defined. * lto-streamer-out.cc (lto_write_mode_table): Stream out NUM_POLY_INT_COEFFS if offloading is enabled. * poly-int.h (MAX_NUM_POLY_INT_COEFFS_BITS): New macro. * tree-streamer-in.cc (lto_input_ts_poly_tree_pointers): Adjust streaming-in of poly_int.
