Missing `.riscv.attributes` section in the output image when bitcode inputs are used #64

partaror · 2025-04-28T10:00:03Z

The output image does not contain .riscv.attributes section when the input contains bitcode inputs.

Reproducible example:

#!/usr/bin/env bash

cat >1.c <<\EOF
int foo() { return 1; }
EOF

clang -o 1.bc 1.c -c -flto -target riscv32
clang -o 1.o 1.c -target riscv32 -c

ld.eld -o 1.eld.out -m elf32lriscv 1.o -T script.t 
ld.eld -o 1.eld.lto.out -m elf32lriscv 1.bc -T script.t

llvm-readelf -S 1.eld.out | grep .riscv.attributes
llvm-readelf -S 1.eld.lto.out | grep .riscv.attributes

Output:

+ cat
+ clang -o 1.bc 1.c -c -flto -target riscv32
+ clang -o 1.o 1.c -target riscv32 -c
+ ld.eld -o 1.eld.out -m elf32lriscv 1.o -T script.t
+ ld.eld -o 1.eld.lto.out -m elf32lriscv 1.bc -T script.t
Note: Using 8 threads for LTO code generation.
+ grep .riscv.attributes
+ llvm-readelf -S 1.eld.out
  [ 2] .riscv.attributes RISCV_ATTRIBUTES 00000000 001012 00004e 00      0   0  1
+ llvm-readelf -S 1.eld.lto.out
+ grep .riscv.attributes
