Bug ID: 28822
Summary: lld: entry is past the end of the section
Product: lld
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: ELF
Assignee: unassignedb...@nondot.org
Reporter: kra...@google.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
While trying to move Chrome to LLD on Linux x86-64 (now it uses the Gold
plugin), I encountered the following issue on multiple targets, if compiled
with CFI:
"entry is past the end of the section"
I was able to reproduce this in LLVM tree. Any C++ file will fit the bill, I
used the following simple.cc:
int main(void) {
return 0;
}
The command line to trigger the bug:
$ clang++ -fuse-ld=lld -flto -fsanitize=cfi -fvisibility=hidden
-fno-sanitize-trap=cfi -g -o simple simple.cc
entry is past the end of the section
clang-3.9: error: linker command failed with exit code 1 (use -v to see
invocation)
After putting debug printfs into the strategic place:
https://cs.chromium.org/chromium/src/third_party/llvm/tools/lld/ELF/InputSection.cpp?q=entry.is.past.the.end.of.the.section&sq=package:chromium&l=552&dr=C
I've got these hints:
Section name: .debug_str
File: sanitizer_linux_s390.cc.o
Size: 0
Offset: 0
