Bug #: 13897
Summary: llc crashes with "UNREACHABLE executed" message
Product: new-bugs
Version: 3.1
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: release blocker
Priority: P
Component: new bugs
AssignedTo: [email protected]

CC: [email protected]
Classification: Unclassified
i have a simple IR file like below:
;;;;;;;;;;;;;
; ModuleID = 'gg.bc'
@aaa = external global i128
@bbb = external global i128
define void @depasta() nounwind {
"0x0":
%0 = load i128* @bbb
%1 = and i128 %0, 4294967295
%2 = shl i128 %0, 96
%3 = mul i128 %1, 18446744078004518913
%4 = add i128 %3, %2
store i128 %4, i128* @aaa
ret void
}
;;;;;;;;;
i tried to compile this IR file to bitcode file (with llvm-as), then
compile BC file to native code (with llc).
however, llc crashes like below:
------
C:\>llvm-as gg.ll
C:\>llc -filetype=obj gg.bc
UNREACHABLE executed!
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
--------
this looks like a bug, doesn't it? any idea why?
this is LLVM 3.1, on Windows 32bit.
