59c33d69ab Revert "m68k: utilize cg.a_loadaddr_ref_cgpara in hlcgcpu" for now, turns out it's not needed 2022-03-24 09:48:25 +01:00

ed520548be m68k: utilize cg.a_loadaddr_ref_cgpara in hlcgcpu, as m68k has an instruction for loading addresses directly to the stack (PEA), and the default implementation of hlcg.a_loadaddr_ref_cgpara doesn't use that code path 2022-03-23 11:06:18 +01:00

be2c1c751d * m68k: fixed the register save/restore for larger than 32K stackframes on subarchs which has no long displacement, to not trash register A0 2022-03-12 21:22:42 +01:00

077a3f1892 * m68k: don't attempt to copy less than 1 byte in g_concatcopy, this fixes tdfa7.pp on 68000 and removes some superfluous address processing on 68020+ in the same test 2022-02-08 03:04:28 +01:00

d0178f7ae0 m68k: fix a_loadfpu_ref_reg to call a_loadfpu_reg_reg instead of a_load_reg_reg. made a_loadfpu_reg_reg internalerror on invalid target sizes when loading to a different reg size

4686f61002 * keep track of the temp position separately from the offset in references,

    (e.g. in case of array indexing or record field accesses) (mantis #33628)

518cdf9674 * replaced the saved_XXX_registers arrays with virtual methods inside 
tcpuparamanager, very similar to the existing get_volatile_registers_XXX. The
  new methods are called get_saved_registers_XXX, where XXX is the register
  type ("int", "address", "fpu" or "mm")

a25ebbba3e + added volatility information to all memory references 
o separate information for reading and writing, because e.g. in a
     try-block, only the writes to local variables and parameters are
     volatile (they have to be committed immediately in case the next
     instruction causes an exception)
   o for now, only references to absolute memory addresses are marked
     as volatile
   o the volatily information is (should be) properly maintained throughout
     all code generators for all archictures with this patch
   o no optimizers or other compiler infrastructure uses the volatility
     information yet
   o this functionality is not (yet) exposed at the language level, it
     is only for internal code generator use right now
