+ (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

+ (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,

+ (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
+
+2005-07-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

+ like CODE pointers, fixes #1115683
