Well, there are 3 ways how to write it.
Either write a plain C testcase which will test SHF_MERGE only if gcc
supports it, or gcc -S and sed the .s file to make plain .rodata sections
.section ".rodata.str", "aMS", @progbits, 1
or have testcase fully in assembly (in which case it will be for one arch
only).
