2a45b57504 * removed todo comment, the "constant" information is already propagated in
the mean time via the section type (sec_rodata/sec_rodata_norel ->
    constant)

eef6f05697 * specify the asm section type when creating an LLVM declaration
o in case it's a read-only section, mark the data as "constant"

394dfdd220 * ensure that all initialised items have a type (and only one):
o remove the accompanying tdef operands from tai operands, because such
     tai operands should have a tdef already
   o check that every queued tai is a tai_simpletypedconst (which have a
     type)
   o wrap queued bitcast/getelementptr tai instances with a
     tai_simpletypedconst

fc7d5e2254 * insert a type conversion if the final result of an queued expression is
different from the type of typed constant/initialised data

ab186e8d75 * override queue_emit_staticvar() and set the offset to 0 there for the same
reason as with queue_emit_asmsym()

8afffdb176 * moved get_string_symofs() to a virtual class method of
ttai_typedconstbuilder so that it can be overridden by other platforms
  * override get_string_symofs() for LLVM and always return 0, as you can't
    have labels in the middle of a declaration on that platform

a284902813 * emit the current offset when flushing tasmsymbols in the
ttai_lowleveltypedconstbuilder
   o set the offset to 0 in the llvm constbuilder before calling
     the lowlevel one, because it incorporates this offset already
     via getelementptr instructions

e0c1c4d3bf + support for merging multiple tai_strings/tai_consts emitted as part of the
same string constant to be merged together into a single tai_string
    (required to efficiently represent string constants in llvm assembler
     --i.e., without splitting them into bytes--, while keeping the
     flexibility in the typed constant parser to mix individual elements
     and strings)

5b884c96f2 + initial llvm implementation of the ttai_typedconstbuilder class
o now simple typed constants (integer, floating pointer, pchar)
     and (non-variant) record typed constants containing such
     elements work for llvm
