README

      1 The files in this directory are a collection of recordings of
      2 the memory allocations of a set of apps.
      3 
      4 In order to run these files through the tool, they will need to be placed
      5 unzipped on the device.

      7 Format of dumps:
      8 
      9 <tid>: <action_name> <ptr> [<optional_arguments>]
     10 
     11 <tid>
     12   The pid_t value that is the gettid() value recorded during the run.
     13 
     14 <action_name> 
     15   One of:
     16     malloc - Allocate memory using the malloc function.
     17     calloc - Allocate memory using the calloc function.
     18     memalign - Allocate memory using the memalign function. This is used
     19                during recording for either memalign or posix_memalign.
     20     realloc - Allocate memory using the realloc function.
     21     free - Free memory allocated using one of the above actions.
     22     thread_done - Terminate the thread with the given tid.
     23 
     24 Format of each action:
     25 
     26 <tid>: malloc <ptr> <size>
     27  Allocation made by malloc(<size>).  <ptr> is the value returned by malloc.
     28 
     29 Example:
     30 
     31 100: malloc 0xb48390a0 48
     32 
     33 <tid>: calloc <ptr> <nmemb> <size>
     34   Allocation made by calloc(<nmemb>, <size>. <ptr> is the value returned
     35   by calloc.
     36 
     37 Example:
     38 
     39 200: calloc 0xb48c1100 32 8
     40 
     41 <tid>:realloc <new_ptr> <old_ptr> <size>
     42   Allocation made by realloc(<old_ptr>, <size>). <old_ptr> can be 0x0
     43   to indicate a realloc with a nullptr. <new_ptr> is the value returned
     44   by realloc.
     45 
     46 Example:
     47 
     48 300: realloc 0x96b90920 0x93605280 150
     49 
     50 <tid>:memalign <ptr> <alignment> <size>
     51   Allocation made by memalign(<alignment>, <size>). <ptr> is the value
     52   returned by memalign.
     53 
     54 Example:
     55 
     56 400: memalign 0xae42d080 16 104
     57 
     58 <tid>: free <ptr>
     59   Find a previously allocated pointer <ptr> and call free(<ptr>).
     60   <ptr> can be 0x0 to indicate the freeing of a nullptr.
     61 
     62 Example:
     63 
     64 500: free 0xb4827400
     65 
     66 <tid>: thread_done 0x0
     67   Indicates that the thread <tid> has completed.
     68 
     69 Example:
     70 
     71 600: thread_done 0x0
     72
