Bug ID: 47108
Summary: Request merge of more AArch64 SVE fixes onto the LLVM
11 Release branch
Product: libraries
Version: 11.0
Hardware: All
OS: All
Status: NEW
Severity: release blocker
Priority: P
Component: Backend: AArch64
Assignee: unassignedb...@nondot.org

Hi, can I ask if it's possible to get the following patches cherry-picked onto
the LLVM 11 release branch?
These fixes are related to CodeGen for AArch64 SVE and fixing issues with
unwind information for SVE objects/registers. All of these fixes are related to
SVE, therefore any behavioural differences can only be observed by compiling
with +sve. There only two minor changes outside lib/Target/AArch64 where we now
permit the printing of additional comments for some unwind info - these
additional comments can only appear for SVE objects.
The fixes are listed here:
0905d9f31ead399d054c5d2a2c353e690f5c8daa David Sherwood [SVE][CodeGen] Fix bug
with store of unpacked FP scalable vectors
f2916636f83dfeb4808a16045db0025783743471 Sander de Smalen [AArch64][SVE]
Disable tail calls if callee does not preserve SVE regs.
bb3344c7d8c2703c910dd481ada43ecaf11536a6 Sander de Smalen [AArch64][SVE] Add
missing unwind info for SVE registers.
fd6584a22043b254a323635c142b28ce80ae5b5b Sander de Smalen [AArch64][SVE] Fix
CFA calculation in presence of SVE objects.
These can be applied easily with:
git cherry-pick fd6584a22043b254a323635c142b28ce80ae5b5b

If you have any problems please don't hesitate to contact me,
Thanks,
David.
