Bug ID: 47630
Summary: regression with mips-linux: Assertion `ShiftAmt <=
BitWidth && "Invalid shift amount"' failed
Product: new-bugs
Version: 11.0
Hardware: All
OS: All
Status: NEW
Severity: release blocker
Priority: P
Component: new bugs
Assignee: unassignedbugs at nondot.org

LLVM 10 debug build (assertions enabled):
[nix-shell:~/Downloads/zig/build-llvm10-debug]$ ./zig test ../lib/std/std.zig
-target mips-linux-none --test-cmd qemu-mips --test-cmd-bin
(ok)
LLVM 11 rc3 debug build (assertions enabled):
[nix-shell:~/tmp/zig/build-llvm11-debug]$ ./zig test ../lib/std/std.zig -target
mips-linux-none --test-cmd qemu-mips --test-cmd-bin
LLVM Emit Output... zig: ../include/llvm/ADT/APInt.h:997: void
llvm::APInt::lshrInPlace(unsigned int): Assertion `ShiftAmt <= BitWidth &&
"Invalid shift amount"' failed.
To reproduce (see following comment for test.ll):
~/local/llvm11-debug/bin/clang-11 -target mips-unknown-linux-unknown test.ll -c
clang-11: ../include/llvm/ADT/APInt.h:997: void
llvm::APInt::lshrInPlace(unsigned int): Assertion `ShiftAmt <= BitWidth &&
"Invalid shift amount"' failed.
PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash
backtrace, preprocessed source, and associated run script.
