Bug ID: 40311
Summary: aarch64-windows: fatal error "SEH unwind data
splitting not yet implemented"
Product: new-bugs
Version: 7.0
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: new bugs
Assignee: unassignedb...@nondot.org
Reporter: dma...@mozilla.com
CC: efrie...@codeaurora.org, htmldevelo...@gmail.com,
llvm-bugs@lists.llvm.org, r...@google.com
With LLVM trunk plus the not-yet-landed SEH support in
https://reviews.llvm.org/D53540, a clang-cl build of Firefox for
aarch64-windows hits this error:
https://github.com/llvm-mirror/llvm/commit/a9be23987d154b0bb53c156c47ae261161af87e8
Are there any plans to implement the unwind data splitting or epilog code
sharing? This looks like the last remaining hurdle for Firefox to use clang-cl
with aarch64-windows builds, so we're pretty keen to follow along with the
progress.
I'm assuming that no reproducer is needed because this is a known limitation,
but let me know if I should include one.
