+       * as/mcs51/lkarea.c: enlarged codemap for banked memory
+       * device/lib/mcs51/crtbank.asm: added # to 0x0F

+
+       * src/pic/gen.c (aopOp): do not generate AOP_ACC operands as pic14
+         architecture cannot handle them efficiently, fixes bug #1235003
+       * src/pic16/device.c (pic16_dump_{u,i}section,pic16_dump_int_registers):
+         check for empty sets before using them (fixes bug #1232190)

+
+       * as/mcs51/lkarea.c (lnkarea, lnkarea2): improved BSEG size calculation,
+         (lnksect2): generate warnings for memory overlap
+       * src/SDCC.lex (doPragma, process_pragma): added pragma's codeseg and
+         constseg to set the name of these segments so you can instruct the linker
+         to place them in banks
+       * src/SDCCast.c (decorateType): use new macro IS_FUNCPTR()
+       * src/SDCCglobl.h: added MODEL_HUGE to enum,
+         added code_seg and const_seg to options
+       * src/SDCCglue.c (emitMaps): use options.const_seg,
+         (createInterruptVect): put interrupt vectors in segment HOME,
+         (glue): put HOME before static segment and put the main glue in HOME,
+         (glue): use options.code_seg
+       * src/SDCCicode.c (geniCodeCall): use new macro IS_FUNCPTR()
+       * src/SDCCmain.c: added option --codeseg and --constseg to set the name of
+         these segments so you can instruct the linker to place them in banks
+         (linkEdit): use code_loc for HOME segment which should be the first
+         segment in code memory now
+       * src/SDCCmem.c: fixed more stuff like bug 1238386
+       * src/SDCCsymt.c (getSize): use generic pointer size for banked functions,
+         (changePointer): don't change function pointers to code pointers for
+         banked functions,
+         (compareType): added exceptional check for banked function pointers
+       * src/SDCCsymt.h: changed IFFUNC_ISBANKEDCALL, added IS_FUNCPTR
+       * src/hc08/main.c (_hc08_genAssemblerPreamble): put HOME first, put CSEG
+         after static in code memory
+       * src/mcs51/gen.c: added aopLiteralLong prototype,
+         (aopForSym): use getSize for functions,
+         (genCall): generate banked calls over one trampoline __sdcc_banked_call
+         in HOME with lsb of address in r0, msb in r1 and bank in r2, use
+         -Wl-bBANKSEG=0xbbaaaa option to set the address (aaaa) and bank (bb) of
+         the segment,
+         (genPcall): use call for literal function pointers and generate banked
+         calls over the one trampoline so there's only one place for the user to
+         modify according to his/hers hardware,
+         (genEndFunction): jump to __sdcc_banked_ret in HOME for banked functions,
+         (genPlusIncr): moved check icount>4 beyond inc dptr optimization
+       * src/mcs51/main.c: added keyword banked,
+         (_mcs51_genExtraAreas): put HOME first followed by GSINIT, STATIC and CSEG
+       * support/Util/SDCCerr.c,
+       * support/Util/SDCCerr.h: added E_BANKED_WITH_CALLEESAVES, registers are
+         needed for passing the bank and address to the trampoline
+       * device/lib/mcs51/crtbank.asm: added for bankswitching
+       * device/lib/mcs51/Makefile: added crtbank
+

+
+       * src/SDCCcse.c (algebraicOpts): fixed loss of volatility
+         for fields at offset 0 of a struct or union as reported
+         on 2005-07-07 in the developer mailing list.
