As the warning is benign, you can safely suppress this warning diagnostic from the tiarmclang command line that invokes the linker using the option “-Xlinker --diag_suppress=10230-D”.
When LTO is enabled during an application build using the tiarmclang compiler toolchain, the linker can potentially emit the following warning:
warning #10230-D: Linking in section my_archive.a<my_file.o>(.myscn), which does not
contain program data
This issue is created internally in the linker when the ELF_SECTION representing .myscn is first created while LTO is enabled. The .myscn section from the original object file contains a section type of SHT_PROGBITS, but when the ELF_SECTION representation of .myscn is constructed during the load phase of the link, the SHT_PROGBITS section type information does not get represented in the ELF_SECTION for .myscn.
Thus, the check for metadata in the .myscn (that also happens during the registration part of the load phase of the link) fails because its section type does not reflect the actual content of the section.
Please note, however, that the SHT_PROGBITS section type is properly restored during the build phase of the link. So the fact that the warning is inadvertently emitted does not affect the success of the link.
If LTO is not enabled, the issue is not encountered because the ELF_SECTION for .myscn is not created until after registration is completed.
