1The files in this directory are a collection of recordings of 2the memory allocations of a set of apps. 3 4In order to run these files through the tool, they will need to be placed 5unzipped on the device. 6 7Format 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 24Format of each action: 25 26<tid>: malloc <ptr> <size> 27 Allocation made by malloc(<size>). <ptr> is the value returned by malloc. 28 29Example: 30 31100: 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 37Example: 38 39200: 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 46Example: 47 48300: 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 54Example: 55 56400: 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 62Example: 63 64500: free 0xb4827400 65 66<tid>: thread_done 0x0 67 Indicates that the thread <tid> has completed. 68 69Example: 70 71600: thread_done 0x0 72
