<p dir="auto" style="color: #28272d; margin: 0;" align="initial">My test code with my libdl-riscv.diff builds completely but I have stuck on some sane setup of BeagleV-Fire for testing. May it be, I try QEMU the first. As for the code, there are warnings and I do not like how <code style='font-size: 90%; color: #18171d; word-wrap: break-word; background-color: #ececef; border-radius: .25rem; margin-top: 0; font-weight: inherit; font-family: "GitLab Mono","JetBrains Mono","Menlo","DejaVu Sans Mono","Liberation Mono","Consolas","Ubuntu Mono","Courier New","andale mono","lucida console",monospace; vertical-align: bottom; white-space: pre-wrap; overflow-wrap: break-word; word-break: keep-all; padding: 2px 4px;'>Elf_Word *where;</code> is assigned <code style='font-size: 90%; color: #18171d; word-wrap: break-word; background-color: #ececef; border-radius: .25rem; font-weight: inherit; font-family: "GitLab Mono","JetBrains Mono","Menlo","DejaVu Sans Mono","Liberation Mono","Consolas","Ubuntu Mono","Courier New","andale mono","lucida console",monospace; vertical-align: bottom; white-space: pre-wrap; overflow-wrap: break-word; word-break: keep-all; padding: 2px 4px;'>where = (Elf_Addr *)(sect->base + rela->r_offset);</code> and used in the function <code style='font-size: 90%; color: #18171d; word-wrap: break-word; background-color: #ececef; border-radius: .25rem; font-weight: inherit; font-family: "GitLab Mono","JetBrains Mono","Menlo","DejaVu Sans Mono","Liberation Mono","Consolas","Ubuntu Mono","Courier New","andale mono","lucida console",monospace; vertical-align: bottom; white-space: pre-wrap; overflow-wrap: break-word; word-break: keep-all; padding: 2px 4px;'>rtems_rtl_elf_reloc_rela()</code>. It would wort to check all relocation cases what should be the length of modified address in the binary image. I expect that it should be sometimes 32-bit Elf_Word for 32-bit targets but 64-bit for 64-bit targets. It should be of native endianning for constants acessed by LW but it should be little-endian when code is modified, because even big-endian RISC-V reads code in little-endian to allow variable length instructions. There rules seems to be mostly followed by the <code style='font-size: 90%; color: #18171d; word-wrap: break-word; background-color: #ececef; border-radius: .25rem; font-weight: inherit; font-family: "GitLab Mono","JetBrains Mono","Menlo","DejaVu Sans Mono","Liberation Mono","Consolas","Ubuntu Mono","Courier New","andale mono","lucida console",monospace; vertical-align: bottom; white-space: pre-wrap; overflow-wrap: break-word; word-break: keep-all; padding: 2px 4px;'>rtl-mdreloc-riscv.c</code> code but I am not 100% confident and warnings make me even more unsure. So it should be check against spec.</p>
