Incorrect handling of multiple return values with v128, causing segmentation fault

[Q1IQ]

Subject of the issue

WasmEdge fails to handle multiple return values when one of them is a v128, causing a segmentation fault.

Test c

program.wasm.txt

(module
  (type (func (param i32 i32) (result i64 v128))) 
  (func $func1 (type 0) (param i32 i32) (result i64 v128)
    i64.const 0x1234567890
    (v128.const i32x4 0x00000004 0x34567890 0x66666666 0x77777777)
  )
  
  (func $main (result i64 v128)
    i32.const 0x12341234 
    i32.const 0x1234    
    call $func1
  )
  
  (export "main" (func $main)) 
)

Your environment

• OS: Ubuntu 20.04
• CPU: amd64
• WAMR version: iwasm 1.2.3
• Command: iwasm --llvm-jit ./program_call_indirect.wasm

Steps to reproduce

Run the WebAssembly module, and get the output:

$  iwasm --llvm-jit  -f main ./program.wasm
fast jit compilation failed: Error: unsupported opcode
failed to compile fast jit function 0
fast jit compilation failed: unknown error
failed to compile fast jit function 1
Segmentation fault (core dumped)

Expected behavior

The module should correctly handle multiple return values including v128. A valid output should look like:

0x1234567890:i64,<0x3456789000000004 0x7777777766666666>:v128

[Q1IQ]

The call_indirect instruction has the same issue. Here is a sample:

(module
  (type (func (param i32 i32) (result i64 v128))) 
  (func $func1 (type 0) (param i32 i32) (result i64 v128)
    i64.const 0x1234567890
    (v128.const i32x4 0x00000004 0x34567890 0x66666666 0x77777777)
  )
  
  (table 2 funcref) 
  (elem (i32.const 0) $func1) 
  
  (func $main (result i64 v128)
    i32.const 0x12341234 
    i32.const 0x1234    
    i32.const 0        
    call_indirect (type 0) 
  )
  
  (export "main" (func $main)) 
)
