A Reusable Aspect for Memory Profiling

例子：

malPro.acc文件：

#include <stdlib.h>
size_t totalMemoryAllocated;
int totalAllocationFuncCalled;
int totalFreeFuncCalled;

void initProfiler() {
totalMemoryAllocated = 0;
totalAllocationFuncCalled = 0;
totalFreeFuncCalled = 0;
}

void printProfiler() {
printf("total memory allocated = %d bytes ", totalMemoryAllocated );
printf("total memory allocation function called = %d ", totalAllocationFuncCalled);
printf("total memory free function called = %d ", totalFreeFuncCalled);
}

before(): execution(int main()) {
initProfiler();
}
after(): execution(int main()) {
printProfiler();
}

before(size_t s): call($ malloc(...)) && args(s) {
totalMemoryAllocated += s;
totalAllocationFuncCalled ++;
}
before(size_t n, size_t s): call($ calloc(...)) && args(n, s) {
totalMemoryAllocated += n * s;
totalAllocationFuncCalled ++;
}

before(size_t s): call($ realloc(...)) && args(void *, s) {
totalMemoryAllocated += s;
totalAllocationFuncCalled ++;
}

before() : call(void free(void *)) {
totalFreeFuncCalled++;
}

mal.c文件：

#include <stdio.h>
#include <malloc.h>
void t1()
{
int *x ;
printf(" core code:hehe ! ");
x = (int *)malloc(sizeof(int) * 4);
printf(" core code:hehe ! ! ");
}
int main()
{
t1();
int *x ;
printf(" core code:hehe ! ! ");
x = (int *)malloc(sizeof(int) * 4);
printf(" core code:hehe ! ! ");
return 0;
}
