1b66995754 * factored out check to determine whether a variable can be subscripted in
inline assembly, and fixed check after r35959 (mantis #32318)
   o can also subscript parameters passed by value on the stack
   o can also subscript local variables, the parameters passed by reference
     that are subsequently copied into a local

4cf2a2672a changes to fix #32043
* changed most of the variables in the assembler readers used to store constants from aint to tcgint 
  as aint has only the size of the accumular while some CPUs (AVR) allow larger constants in instructions
+ allow access to absolute symbols with address type in inline assembler
* allow absolute addresses in avr inline assembler
+ tests

61af0fb72d * only take into account the location of the parameter at the callee side to
determine whether it's in a register if it's a pure assembler routine
  * you can't "index" implicit pointers either using their fields

aa82e00615 * fixed check to determine whether a record parameter can be subscripted
directly in inline assembly: that's only possible if it's a register
    parameter where the address of the record was passed (rather than the
    record itself), or if a parameter has been explicitly typecasted in
    Intel-style assembly using ".size"

aa1be3276f - removed default value of _typ parameter of TAsmData.(Weak)RefAsmSymbol():
it was AT_NONE, which is invalid and should never be used
  * explicitly pass the correct value for all calls to those methods elsewhere
    in the compiler

1cb8c0d00c * specify the def of assembler level symbols defined via
tasmdata.DefineAsmSymbol() and all routines that call it
   o will be used to automatically generate AB_INDIRECT sybols when
     necessary

1e227f78fe * factored out the check for whether we have to generate dotted function
names, and disabled them for ppc64 ELFv2
  * disabling those also disables the function descriptors, so use the
    _CALL_ELF compiler variable to check whether there is in fact a
    function descriptor

3380b58695 * when we get near the limit of the maximum number of TOC entries that can
be generated for a single object file on AIX, automatically switch to
    an indirection scheme that uses much less TOC entries, but is slower to
    access global variables
  * manually merged infrastructure for target-specific code generation
    switches from JVM branch (-CTxxx switches)
  * -CTsmalltoc switch for AIX that forces the indirection scheme for TOC
    entries from the start in case the automatic one does not conserve
    a sufficient amount (or in case you bump up against the global TOC
    entries limit during linking)

69e01418bb * set the type of record/object/class method symbols to AT_FUNCTION
* in case of a jump/call to an AT_FUNCTION symbols on
    systems_dotted_function_names platforms, prepend a dot to the symbol
    name in assembler code

b738657bf3 * on AIX, functions are called via function descriptors whose name
is '.' followed by the function symbol name (like on linux/ppc64)

335bc9fd46 + PIC support for darwin/ppc32 (-Cg works now, no regressions in test
suite compiled with -Cg compared to without -Cg)
  + support for using a virtual register as PIC/got base register
  * moved got loading code from ncgutil to cgobj/cgcpu (can't test whether
    it didn't break anything under linux/i386, because "make cycle OPT=-Cg"
    was already broken due to the *prt*.as -> si_*.pp changes)
