Bug ID: 49166
Summary: Assertion `V->getType()->isIntOrIntVectorTy() &&
DestTy->isIntOrIntVectorTy() && "Can only zero
extend/truncate integers!"' failed
Product: clang
Version: 11.0
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P

Hi,
There is an assertion failure on version 11.1.0. But it also affects other
versions (I additionally test it with 12.0.0 and my apt-installed 6.0.0).
Details of version 11.1.0 are attached below. With version 6.0.0 (w/o
assertion), it encounters a fatal error in backend.
I suspect it is due to the inlined asm. Additionally, the poc file can be
successfully compiled by gcc.
My system is Ubuntu 18.04, x86-64. Please let me know if there is anything I
can help with. Thanks!

PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash
