Tool/software:
I am not able to print the Static Global Variable in the Map file. I am using linker option in the CSS IDE "--mapfile_contents=sym_defs" but still it is not adding the variables. I tried modifying the linker cmd file to add the section like .ebss > RAM and .bss > RAM but not luck. Please suggest me some linker option how to add variables in the Map file.
For the source file that defines one static variable which does not appear in the map file, please follow the directions in the article How to Submit a Compiler Test Case.
In addition, please rebuild the entire project. From the build log, capture the text of the linker command, and all the system response. Do not use a screenshot. Ignore the Problems view. Paste that text into your next post.
Thanks and regards,
-George

Thank you for the test case. It defines several static variables that are never referenced in that file. Because they are static, it is impossible for another file to reference these variables. These variables are optimized away before linking. The linker never sees them.
Consider this small example.
C:\examples>type example.c const static int not_used = 10; C:\examples>cl2000 --keep_asm example.c "example.c", line 1: warning: variable "not_used" was declared but never referenced C:\examples>findstr not_used example.asm <no system response>
The first command shows the source file. The second command builds it. The option --keep_asm says to keep the compiler generated assembly file. The third command searches the assembly file for the variable name not_used. It isn't there, because it was optimized away.
The same thing happens with your static variables.
Thanks and regards,
-George
Hi George, I have deleted most of the function calls from the Preprocessed file. Those static variables are referenced within in the file. I just wanted to ask what are the ways to make those static variable come in the map file.
Because the static variables are const qualified similar to ...
const static int static_variable = 100;
... the compiler optimizes them out. As a build only experiment, pick one of these variables, remove const, and add code that updates the variable in a non-trivial way. Does it show up the map file?
Thanks and regards,

Hi, there is no issue for the variable declared with const keyword. Issue happens only if variable declared as static. I tried removing static by keeping constant. It does shows in the map file. Once again if I put back the static keyword it is removing the map file.
Suppose you write something similar to ...
/* not const */ static int static_variable = 100;
and there is code in the file which reads and writes static_variable in a non-trivial way. In such case, the compiler does not optimize static_variable away. Therefore, static_variable appears in the map file. Please confirm this is your experience.
Thanks and regards,

Hi George, can we connect over call once.? Let me know the possible way to connect with you.
I am ok with Teams, Google Meet, Zoom.
Answering to your question I am trying these options while compiling and printing map file.
Original Variable declared in code file is "static const fixed16_t cyclic_checks_current_threshold = 262144L;"
Option #1
I removed static keyword from the variable and compiled. It shows this variable in map file.
const fixed16_t cyclic_checks_current_threshold = 262144L;
Option # 2
I removed both static and const keyword from the variable and compiled. It shows this variable in map file.
fixed16_t cyclic_checks_current_threshold = 262144L;
Option # 3
I put back the static keyword to the variable and compiled. It does not show up in map file.
static fixed16_t cyclic_checks_current_threshold = 262144L;
I am using below compiler options in the build process. Please suggest if anything I need to remove from compiler option and need to add in compiler option that will not optimize the global static variable to come in the map file.

I strongly suspect, for each case, the reason the static variable does not appear in the map file is that it is optimized away. Here is a way to verify my guess. Go back to my second post in this thread. Notice how I use the compiler option --keep_asm, and then search the assembly code for the name of the variable of interest. Please perform that analysis for every case where the static variable is not in the map file.
Please understand that this optimization related to static variables occurs early in compiler processing. There is no way to disable it.
Thanks and regards,
