ARM-CGT: armcl.exe how to generate ".map" file with every variable's memory address information?

Part Number: ARM-CGT

description

1.I use "-m project.map" to generate the map file, but some variable don't have memory address information,such as Rte_InitState

2.Then I use "--mapfile_contents=all \ -m project.map" to generate the map file, the information add "load addr", but not clearly indicates the memory address(such as .text/.data/.rodata/.bss),

is there any other parameter for me to achieve this purpose

I'm confused. Your first screen shot is from the part of the map file that lists the global symbols in address order. It starts like this ...

GLOBAL SYMBOLS: SORTED BY Symbol Address 

address   name                           
-------   ----

The first column is the address. So, the address for the symbol Rte_InitState is 0x958582a4.

Thanks and regards,

hello，

1. I mean i want to know which section(text/data/bss) the variable "Rte_InitState" is belonged to?

2. I see some information below, what is "$a" and "$C$CON168" mean, there is other symbol with "$***", where i can find all the "$***" mean?

It belongs to a section named .MSR_VAR_CLEARED:init. This syntax means init is a subsection of .MSR_VAR_CLEARED.

These are the names of symbols, generated by the compiler, which are scoped to a file or function. They always have the binding local. For your purposes, it probably best to ignore them.

Thanks and regards,

If i add this parameter "--mapfile_contents=all" , the "project.map" file will include all the information in "project.map"?

Is this information the most complete?

That's correct. For more detail, please search the TI ARM assembly tools manual for --mapfile_contents.

Thanks and regards,
