[LLVMdev] Clang incompatible with GCC on Linux + ARM Cortex-A9
...alignment strategy of Clang confused me. I wrote a small program to print the structure layout of the following and compiled it with both Clang and GCC.
struct S {
pthread_mutex_t mutex;
pthread_cond_t cond;
int32_t int32_1;
int32_t int32_2;
};
The output are as following (the format is: field_address (+offset): field_name; field_size):
gcc
0xbe92d588 (+0) : mutex ; 24
0xbe92d5a0 (+24): cond ; 48
0xbe92d5d0 (+72): int32_1 ; 4
0xbe92d5d4 (+76): int32_2 ; 4
clang
0xbe856580 (+0) : mutex ; 24
0xbe856598 (+24): cond ; 48
0xbe8565d0 (+80): int32_1 ; 4
0xbe8565d4 (+84): int32_2 ; 4
I don't...
