Bug ID: 52330
Summary: lld/mac crashes when ICFing code with undefs
Product: lld
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: MachO
Assignee: unassignedb...@nondot.org
Reporter: nicolaswe...@gmx.de
CC: g...@fb.com, jezr...@gmail.com,
llvm-bugs@lists.llvm.org, smee...@fb.com
I noticed this in .s form while working on PR51999 (not caused by the fix
there). Turns out it's easy to hit from .c files too:
% cat foo.c
void g();
int main() { g(); }
% out/gn/bin/clang foo.c -fuse-ld=lld -Wl,--icf=all --target=arm64-apple-macos
-isysroot $(xcrun -show-sdk-path -sdk macosx) -fno-exceptions
foldIdenticalSections symbol kind
UNREACHABLE executed at ../../lld/MachO/ICF.cpp:250!
We shouldn't crash here but emit an "undefined symbol" error instead.
(I'll take a look.)
