I'm looking through gcc's source code in preparation for writing a patch to
implement
https://gcc.gnu.org/pipermail/gcc-patches/2023-November/636563.html, but I
can't seem to find the code responsible for replacing format strings such
as %= within the AssemblerTemplate with their target values. Does anyone
know where the code for this is located? I've searched through
resolve_asm_operand_names, finish_asm_stmt and friends, but still can't
find it...

best regards,
Julian
