Bug ID: 40876
Summary: [aarch64] clang-cl 8.0rc2 generates unwind data that
llvm-readelf cannot parse
Product: new-bugs
Version: 8.0
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: new bugs
Assignee: unassignedb...@nondot.org
Reporter: froy...@gmail.com
CC: htmldevelo...@gmail.com, llvm-bugs@lists.llvm.org
In:
https://github.com/froydnj/aarch64-xdata-bug
is an aarch64 windows .obj file, generated by "clang 8.0.0 tags/RELEASE_800/rc2
353414". Running `llvm-readelf -unwind $OBJ` produces an error message:
LLVM ERROR: .xdata must be at least 8 bytes in size
with truncated output.
I'm not sure whether clang is at fault here or whether llvm-readelf is doing
the wrong thing.
The preprocessed source for the file is included, and cmdline.txt contains the
command-line used to compile the file.
