I fail to see how this thread is fundamentally different from the 1st question in your first thread:
How to extract operand size in bits of a C program? nor why you believe that changing from an addition to a multiplication should cause a different answer than what you received in post #2 in that thread??? Is there some reason why you believe the answer I provided there is wrong?
I suppose if you really wanted to you could try to write a C language parser in a shell script to look for every multiplication operation in the C and assembler source files it is asked to process and instead of producing object code emits sizes of the types of the variables or constants being multiplied. And, if what you really want is the highest bit set in the results of each of those multiplications (as in the second question in your first thread), you would not only have to produce runnable object code, but also run them with real data and have your compiler add code to that object code that would print he highest bit set after each multiplication operation found in the source files you processed with your compiler.
I won't say it is impossible to do this, but shell is certainly not the language of choice for a project like this.

platform::shell
platform::shell(n) Tcl Bundled Packages platform::shell(n)
__________________________________________________________________________________________________________________________________________________
NAME
platform::shell - System identification support code and utilities
SYNOPSIS
package require platform::shell ?1.1.4?
platform::shell::generic shell
platform::shell::identify shell
platform::shell::platform shell
_________________________________________________________________
DESCRIPTION
The platform::shell package provides several utility commands useful for the identification of the architecture of a specific Tcl shell.
This package allows the identification of the architecture of a specific Tcl shell different from the shell running the package. The only
requirement is that the other shell (identified by its path), is actually executable on the current machine.
While for most platform this means that the architecture of the interrogated shell is identical to the architecture of the running shell
this is not generally true. A counter example are all platforms which have 32 and 64 bit variants and where a 64bit system is able to run
32bit code. For these running and interrogated shell may have different 32/64 bit settings and thus different identifiers.
For applications like a code repository it is important to identify the architecture of the shell which will actually run the installed
packages, versus the architecture of the shell running the repository software.
COMMANDS
platform::shell::identify shell
This command does the same identification as platform::identify, for the specified Tcl shell, in contrast to the running shell.
platform::shell::generic shell
This command does the same identification as platform::generic, for the specified Tcl shell, in contrast to the running shell.
platform::shell::platform shell
This command returns the contents of tcl_platform(platform) for the specified Tcl shell.
KEYWORDS
operating system, cpu architecture, platform, architecture
platform::shell 1.1.4 platform::shell(n)
