Bug ID: 48480
Summary: [AVR] clang++ crashes compiling inline assembly for
_crc_ccitt_update
Product: libraries
Version: 11.0
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: Backend: AVR
Assignee: unassignedbugs at nondot.org
Reporter: david.hebbeker at gmail.com
CC: llvm-bugs at lists.llvm.org

--> https://bugs.llvm.org/attachment.cgi?id=24265&action=edit
source code to be compiled crc.cpp
clang++ crashes attempting to compile attached code with inline assembly.
In order to reproduce, compile attached source file crc.cpp like this:
clang++ -v -c --target=avr crc.cpp
The result is that the command fails (running pass 'AVR Assembly Printer').
Backtrace attached below. I expected that clang would either output compiled
code or report an error in the code to be compiled in a readable form.
The source file is a reduced minimal crashing code. Originally attempting to
compile the function `_crc_ccitt_update` in [crc16.h][1] which is part of the
[avr-libc][2].
