[lldb-dev] Passing as argument an array in a function call

[Dean De Leo via lldb-dev]

Hi,

assume we wish to use the expression evaluator to invoke a function from lldb, setting the result into an array passed as parameter, e.g:

void test1(uint32_t* d) {
     for(int i = 0; i < 6; i++){
         d[i] = 42 + i;
     }
}

where the expected output should be d = {42,43,44,45,46,47}. However performing the following expression having as target android/mips32 returns:

(lldb) expr -- uint32_t data[6] = {}; test1(data);  data
(uint32_t [6]) $4 = ([0] = 0, [1] = 2003456944, [2] = 44, [3] = 45, [4] = 2004491136, [5] = 47)

Is this an expected behaviour or a bug? I suspect the evaluator allocates the memory for data and releases once the expression has been executed?

If so, can you please advise what's the proper way to achieve the same functionality?


Thanks,
Dean
