How to get the name of the toolchain size command?

[ilg-ul]

I have toolchain definitions like:

arm-none-eabi-gcc.ini

[binaries]
c = 'arm-none-eabi-gcc'
cpp = 'arm-none-eabi-g++'
strip = 'arm-none-eabi-strip'
ar = 'arm-none-eabi-gcc-ar'
ranlib = 'arm-none-eabi-gcc-ranlib'
size = 'arm-none-eabi-size'

and similarly for Windows:

arm-none-eabi-gcc-cmd.ini

[binaries]
c = 'arm-none-eabi-gcc.cmd'
cpp = 'arm-none-eabi-g++.cmd'
strip = 'arm-none-eabi-strip.cmd'
ar = 'arm-none-eabi-gcc-ar.cmd'
ranlib = 'arm-none-eabi-gcc-ranlib.cmd'
size = 'arm-none-eabi-size.cmd'

In order to run the size command within a custom target, I need to get the actual command name, regardless the build platform.

I checked the functions available in the compiler and meson objects, but I could not identify one to return the command associated with one tool.

Any suggestions?

The binaries table overrides the result of find_program('size'), and additionally will be used when Meson internally looks up programs as part of the compiler toolchain handling.

https://mesonbuild.com/Machine-files.html#binaries

The binaries section contains a list of binaries. These can be used internally by Meson, or by the find_program function.

I confirm, find_program('size') returns the name of the command as defined in the cross.ini file.

Thank you!
