It generates the list of global variables which have greater size than given.
Please find the usages with -h option.
tools/memory$ ./g_var_profiler.sh -h
Usages: ./g_var_profiler.sh [-s SIZE] [-e ELF] [-o OUTPUT_FILENAME]
This script parses the global variable which size is greater than [SIZE]
If no input params are specified, below is assumed
SIZE : 256
ELF : ../../build/output/bin/tinyara
OUTPUT_FILENAME : var_list_over_SIZEbytes.txt
Output file info
SIZE : variable size(bytes)
TYPE : you can refer to this site <https://sourceware.org/binutils/docs/binutils/nm.html>All of options are optional. When they are not specified, default values are used as explained in help.
tools/memory$ ./g_var_profiler.sh -s 1024
Size : 1024
ELF : ../../build/output/bin/tinyara
Output : var_list_over_1024bytes.txt
var_list_over_1024bytes.txt is generated.
