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. 6 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
