In GCC 15.2 we have enabled RVA23 extensions including vector instructions. When trying to rebuild the package an error occurs. This has been reported to GCC upstream in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=121512. Since release 1.2.0 highway has received RISC-V vector related fixed, e.g. 9cff02ac65ac ("Fixes to compilation errors with RVV with EMU128 or SCALAR baseline") #!/bin/sh /usr/bin/c++ \ -g \ -O2 \ -freport-bug \ -fno-omit-frame-pointer \ -ffile-prefix-map=/home/${USER}/workspace/build-highway/highway-1.2.0=. \ -flto=auto \ -ffat-lto-objects \ -fstack-protector-strong \ -Wformat \ -Werror=format-security \ -fno-stack-clash-protection \ -fdebug-prefix-map=/home/${USER}/workspace/build-highway/highway-1.2.0=/usr/src/highway-1.2.0-3ubuntu3 \ -DHWY_BROKEN_EMU128=0 \ -Wdate-time \ -D_FORTIFY_SOURCE=3 \ -Wl,-Bsymbolic-functions \ -flto=auto \ -ffat-lto-objects \ -Wl,-z,relro \ -Wl,-z,now \ -fPIE \ -pie \ -Wl,--dependency-file=CMakeFiles/hwy_benchmark.dir/link.d CMakeFiles/hwy_benchmark.dir/hwy/examples/benchmark.cc.o \ -o examples/hwy_benchmark \ -Wl,-rpath,/home/${USER}/workspace/build-highway/highway-1.2.0/obj-riscv64-linux-gnu libhwy.so.1.2.0 during RTL pass: expand In function ‘BitCastToByte’, inlined from ‘BitCast’ at /usr/src/highway-1.2.0-3ubuntu3/hwy/ops/rvv-inl.h:901:33, inlined from ‘Zero’ at /usr/src/highway-1.2.0-3ubuntu3/hwy/ops/rvv-inl.h:695:17, inlined from ‘operator()’ at /usr/src/highway-1.2.0-3ubuntu3/hwy/examples/benchmark.cc:118:18, inlined from ‘operator()’ at /usr/src/highway-1.2.0-3ubuntu3/hwy/examples/benchmark.cc:75:61, inlined from ‘CallClosure’ at /usr/src/highway-1.2.0-3ubuntu3/hwy/nanobenchmark.h:154:14: /usr/src/highway-1.2.0-3ubuntu3/hwy/ops/rvv-inl.h:866:1: internal compiler error: in generate_insn, at config/riscv/riscv-vector-builtins.cc:4470 0x243847d internal_error(char const*, ...) ../../src/gcc/diagnostic-global-context.cc:517 0x5b67bf fancy_abort(char const*, int, char const*) ../../src/gcc/diagnostic.cc:1749 0xdd60bf riscv_vector::function_expander::generate_insn(insn_code) ../../src/gcc/config/riscv/riscv-vector-builtins.cc:4470 0xdd60bf riscv_vector::function_expander::generate_insn(insn_code) ../../src/gcc/config/riscv/riscv-vector-builtins.cc:4468 0xdde4fd riscv_vector::function_expander::expand() ../../src/gcc/config/riscv/riscv-vector-builtins.h:688 0xdde4fd riscv_vector::expand_builtin(unsigned int, tree_node*, rtx_def*) ../../src/gcc/config/riscv/riscv-vector-builtins.cc:4990 0x72cb91 expand_expr_real_1(tree_node*, rtx_def*, machine_mode, expand_modifier, rtx_def**, bool) ../../src/gcc/expr.cc:12499 0x733497 store_expr(tree_node*, rtx_def*, int, bool, bool) ../../src/gcc/expr.cc:6771 0x734575 expand_assignment(tree_node*, tree_node*, bool) ../../src/gcc/expr.cc:6492 0x647a85 expand_call_stmt ../../src/gcc/cfgexpand.cc:3143 0x647a85 expand_gimple_stmt_1 ../../src/gcc/cfgexpand.cc:4218 0x647a85 expand_gimple_stmt ../../src/gcc/cfgexpand.cc:4365 0x64bce3 expand_gimple_basic_block ../../src/gcc/cfgexpand.cc:6483 0x64bce3 execute ../../src/gcc/cfgexpand.cc:7232 Please submit a full bug report, with preprocessed source.
