Bug ID: 26057
Summary: [Statepoint] Lowering integer larger than 64 bits as
deopt argument crashes
Product: libraries
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Common Code Generator Code
Assignee: unassignedb...@nondot.org
Reporter: listm...@philipreames.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
The following test case crashes:
define void @test5(i28 %arg) gc "statepoint-example" {
%safepoint_token = call token (i64, i32, void ()*, i32, i32, ...)
@llvm.experimental.gc.statepoint.p0f_isVoidf(i64 0, i32 0, void ()*
@do_safepoint, i32 0, i32 0, i32 0, i32 2, i128 %arg, i128 0)
ret void
}
This is exercising two different cases of trying to encode a 128 bit integer
into the stackmap. The argument appears to cause a legalization bug. The i128
bit constant works, but only because the actual constant is encodable in 64
bits. A 10..62..0 constant would not be.
