Summary: llc 2.9 is failing failing to compile following
example for ARM Cortex-A9
Product: new-bugs
Version: 2.9
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P
Component: new bugs
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
On following code:
define arm_aapcscc void @test_convert_ushort2_ulong2(<2 x i64>* nocapture %src,
<2 x i16>* nocapture %dest) nounwind {
L.entry:
%0 = load <2 x i64>* %src, align 16
%1 = trunc <2 x i64> %0 to <2 x i16>
store <2 x i16> %1, <2 x i16>* %dest, align 4
ret void
}
When compiling for arm cortex-a9 target using following command line:
llc -march=arm -mcpu=cortex-a9 conv.ll -s conv.s
I've got following internal error message:
LLVM ERROR: Cannot select: 0x812dab0: v4i16 = extract_subvector 0x812de68,
0x812d780 [ID=10]
0x812de68: v4i32 = bit_convert 0x812d9a0 [ID=9]
0x812d9a0: v2f64,ch = load 0x811a404, 0x812d5e8, 0x812d808<LD16[%src]>
[ID=8]
0x812d5e8: i32,ch = CopyFromReg 0x811a404, 0x812d560 [ORD=1] [ID=6]
0x812d560: i32 = Register %vreg0 [ORD=1] [ID=1]
0x812d808: i32 = undef [ORD=1] [ID=3]
0x812d780: i32 = Constant<0> [ID=4]
If I remove -mcpu=cortex-a9 from command line, it compiles successfully
