Bug ID: 48062
Summary: STB_LOCAL symbol found at index >= .symtab's sh_info
Product: lld
Version: unspecified
Hardware: Other
OS: other
Status: NEW
Severity: release blocker
Priority: P
Component: ELF
Assignee: unassignedbugs at nondot.org
Reporter: xavi.dcr at tutanota.com
CC: llvm-bugs at lists.llvm.org, smithp352 at googlemail.com
I am using llvm-project commit 8fc424f26bf1ea1471bd770a1b4eee4545c2bc96 with
two additional patches for preliminary MIPS I support (see
https://github.com/llvm/llvm-project/compare/release/11.x...XaviDCR92:release/11.x)
and zig (https://github.com/ziglang/zig) commit
b30a765b95cf666409c1e5324718a7c8c60af4af for an application targeted to the
FPU-less MIPS R3000A featured on the original Sony PlayStation.
The application uses mipsel-unknown-elf-as for the assembly files, which are
later linked by lld when calling zig. The application used to build on
llvm-10.x (plus the experimental patches) and older versions of zig, but does
no longer build on llvm-11.x and latest zig. After some discussion on the #zig
channel, I was encouraged to report this issue here based on the "lld:error: "
messages shown below.
As an alternative, I have tried to assemble the assembly files directly from
zig, but unfortunately the assembler does not recognize the "rfe" (return from
exception) MIPS I instruction for some unknown reason:
This is the output when building everything from zig:
