1756 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1758 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1759 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1761 One basic decision: e.g. src/clean.mk includes further files. In order
1762 to make this work there are two solutions:
1763 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1764 run configure on them. This way they can use
1765 'include $(srcdir)/port-clean.mk'
1766 - always include clean.mk by the Makefile at the same level. To avoid
1767 that `make clean` tries to include and build Makefile.dep the
1768 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1769 implemented, because now even `make uninstall` doesn't create
1770 Makefile.in. clean.mk could be eliminated by pasting it in
1773 * debugger/mcs51/Makefile.in: build own objects from library sources
1774 (SLIB, SDCC) in current directory
1776 * configure, configure.in: renamed --disable-device-lib-build in
1777 --disable-device-lib; added --enable-doc, the required tools are
1778 searched by configure; added result message; the toolchain for the
1779 belonging ports are now only built, if the port is enabled.
1781 * support/regression/*: all output is written in directory gen, because
1782 the fwk and ports directories don't livet in the build tree using vpath

2039 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
2041 * src/mcs51/gen.c (genCall): fixed bug 1457608
2043 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

2062 implemented patch 1120823 Thanks to Willy De la Court (normal
2063 interrupts need an interrupt number now if they are made critical),
2064 and enabled nesting of critical functions though not for gbz80
2065 (genCritical, genEndCritical): added functions
2066 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2067 * src/z80/mappings.i: added "ei" to all mappings

2079 the left operand is shorter than the result (c* = lit-c* + int),
2081 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2084 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2086 * src/.version: increased version number to 2.5.5
2087 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2088 linking is done manually in pic16 port's _linkEdit,
2089 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2090 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2091 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2092 allocate asmop as AOP_ACC,
2093 (aopForRemat): added parameter 'bool result' in function declaration,
2094 (pic16_aopGet): return AOP_ACC when accessing WREG,
2095 (pic16_popGetTempReg): minor modification,

2106 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2107 call to allocReg, not by manually allocating a new one,
2108 (pic16_assignRegisters): now before going through the register
2109 allocating functions mark all registers as free. This eliminates some
2110 side effects resulting from peephole parser done earlier in the backbone
2112 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

2162 2006-03-06 Borut Razem <borut.razem AT siol.net>
2164 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
2165 made the linker quiet
2167 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
2169 * src/pic16/gen.c (genPcall): fixed bug #1443644
2170 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2171 which dumps before the function entry point a data byte which represents
2172 the number of the local variables used by the specified function, added
2173 'xinst' for initial support for Extended Instruction Support,
2174 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2175 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2176 port->fun_prefix anymore (may change later),
2177 (genFunction, genEndFunction): do not store/restore local registers for
2178 _main (this should take care the --main-return command line option in
2180 (genOr): removed some legacy pic-port instructions,
2181 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2182 performing operations with SFR's causes data to be written more than
2183 once to each SFR. Perhaps SFRs should be handled in special cases...
2184 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2186 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2187 into account for stack starting position,
2188 (struct OPTIONS pic16_optionsTable): added command line argument
2189 --extended or -y for Extended Instruction Support,
2190 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2191 (deassignLRs): *** perhaps the most important change, old 'for' code
2192 (commented out for reference), didn't account for some registers which
2193 were left marked 'not free' after a pointer operation. The change
2194 reduces register usage a lot in some cases
2196 2006-03-04 Borut Razem <borut.razem AT siol.net>
2198 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

4469 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4470 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4471 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4472 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4473 always available in leading double underscore form. The C99 support is
4474 mostly missing, but it's a start.
4475 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4476 reserved identifier "__data".

4554 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4556 * device/lib/printf_large.c: removed inline assembly for portability and
4557 readability. Use printf_fast if speed or size are more important.
4558 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4559 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4561 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4563 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4564 prevent compiler warning
4566 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4568 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4569 moved to level 0 and declared as static. Also they are explicit
4570 placed in access bank. This was necessery because some times they
4571 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4572 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4573 optimizations. Currently only compare to unsigned char is implemented,
4574 * src/pic16/gen.c: added fReturnIdx array,
4575 * (struct resolvedIfx) is moved to gen.h and made public,
4576 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4577 * (aopForSym): added an optimization to directly store in stack of
4578 the operand of a SEND iCode,
4579 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4580 but as registers instead (AOP_REG) using the fReturnIdx array,
4581 * (pic16_freeAsmop): remove the freed register from the
4582 _G.sregsAlloc field,
4583 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4584 a compare of 'WREG',
4585 * (pic16_popGetTempRegCond): changed function prototype, now
4586 function takes also a bitVector argument v which holds the current
4587 set of registers that are allocated for stack access by aopForSym,
4588 registers allocated in aopForSym for accessing stack symbols are not
4589 any more part of the functions usedRegs field,
4590 * (genCall): some times aopOp is called for a stack variable to be
4591 send, aopForSym might perform the push, if this is true make sure
4592 that genCall doesn't push the variable twice by testing _G.resDirect,
4593 * (genFunction): changed testing for unspecified interrupt number
4594 from 256 to INTNO_UNSPEC,
4595 * modified selection scheme of frame pointer generation. Previously
4596 if function did use local registers a frame pointer was generated,
4597 now a frame pointer is generated only if function has arguments
4598 (that need PLUSW2 register access), or has stack arguments, or the
4599 compiler is not instructed to omit the frame pointer,
4600 * (genEndFunction): before restoring local registers that were saved
4601 in the function preamble, also restore the registers that *might*
4602 have been allocated for stack access,
4603 * (genRet): removed some old comments,
4604 * (genCmp, the active (RN's) version): added a call to the
4605 pic16_genCmp_special function to perform the compare with a more
4606 robust and optimized way,
4607 * (genInline): a feature has been added in inline code generation,
4608 which allows a wildcard variable substitution when writing inline
4609 assembly. Code is incomplete and experimental therefore undocumented,
4610 * (genCast): changed order of aopOp for result and right to allow
4611 aopForSym to directly load the result if possible,
4612 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4613 perform an optimized compare on some selected special occasions,
4614 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4615 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4616 generate an IVT any more,
4617 * src/pic16/main.c (pic16_optionsTable): added command line option
4619 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4620 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4622 * src/pic16/NOTES: Raphael Neider added in list of active developers
4623 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4624 jumptable_end to prevent bug #,
4625 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4626 inCond and outCond fields,
4627 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4628 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4629 turn off register spilling,
4630 * (packRegsForOneUse): synced with other ports' versions although it
4631 is not used currently,
4632 * (pic16_packRegisters): added an optimization while reading
4633 structure bitfields, some registers may be saved (malloc code is
4634 decreased by 80 bytes)
4636 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4638 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4639 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4640 this can be optimized more?
4642 2005-03-10 Raphael Neider <rneider AT web.de>
4644 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4645 genNearPointerGet): (hopefully) fixed access to bitfields via
4646 pointers (p->bitN = x; and x = p->bitN; failed)
4648 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5280 Adding support for replacing ljmps with sjmps in jumptables
5281 generated for switch statements. For now you need to set the
5282 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5283 Now 4 algorithms for mcs51 jumptable generation are used:
5284 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5285 addresses loaded pc-relative for up to 112 cases and stack-pushing
5286 target addresses loaded with offset from dptr for up to 256 cases.

5316 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5318 * added libc directory. The current version of LibC contains string
5319 functions, ctype functions and macros and some functions of the
5320 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5321 be extensively tested in the future. Standard disclaimer here.
5322 Library is not automatically build yet. But one can build it by
5323 invoking 'make' inside the libc directory.
5324 * added ADC library under libio. Preliminary version yet.

5334 * (pic16_storeForReturn): optimized return of 0,
5335 * (genCmp): experimental code for new genCmp which uses PIC18's
5336 special compare&skip instructions. Initial tests fail some times
5337 with variables grater than 1 byte in size, so new code is disabled,
5338 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5340 * (genCast): began a fix to optimize the casting of a bit to another
5341 bit, now assigning a bitfield to another bitfield will fail, sorry,
5342 * src/pic16/main.c: disabled the use of lr-support feature,
5343 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

5350 and 1 for banking instruction,
5351 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5352 caused stop processing pCodes after a inline assembly block,
5353 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

5355 registers when it shouldn't,
5356 * src/pic16/ralloc.c (allocReg): add preliminary support for
5357 supporting a limited set of temporary registers,
5359 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5361 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

8267 * support/regression/ports/ucz80/spec.mk (UCZ80): Made detect the
8270 * support/regression/generate-cases.py (main): Changed from inline
8273 * doc/Makefile (install): Changed to depth first to get rid of
8274 missing directory install warning.
8276 * as/Makefile (install-doc): Made work on Mac.
8278 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
8280 * src/SDCCast.c: added an additional type flow in decorateType() of
8281 opposite direction, see feature request #860006; it's enabled at runtime
8282 by setting the environment variable SDCC_NEWTYPEFLOW
8283 * src/SDCCast.h: changed prototype of decorateType()
8284 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
8285 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
8286 'char' to 'int' can be omitted, if both operands are 'unsigned char';
8287 see feature request #877103
8288 * src/SDCCval.c: updated call of decorateType()
8289 (valBitwise): fixed bug #882876
8290 (valMinus): added promotion
8291 (valLogicAndOr): result is unsigned
8292 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
8293 * src/SDCCsymt.c (computeType),
8294 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
8295 must not cause an unsigned operation
8296 * src/pic/glue (pic14emitRegularMap),
8297 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
8299 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>

8316 * src/pic/ralloc.h: applied patch from Slade Rich;
8317 added support for multiple code pages and multiple RAM banks on the
8318 PIC 14 port. The ASM files now no longer simply assume all the
8319 code / RAM are in the same page / bank. This means the linker can
8320 safely allocate code/RAM of separate ASM files to different pages/banks.
8321 * doc/sdccman.lyx: added Slade's tips
8322 * src/mcs51/peeph.def: fixed bug #880768

8331 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
8334 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
8335 strtof is not part of C89 and isn't included with Mac OS X.
8337 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8339 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

8364 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8366 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8367 loaded with the linker search paths (-L arguments) and the libraries
8368 to be linked with the current source (-l arguments). Changes
8369 currently will affect only the pic16 port.
8370 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8371 include path the port specific paths and port specific libraries,
8372 * gplink command now contains the $3 argument,
8373 * src/pic16/device.h,
8374 * src/pic16/device.c,: structure PIC_device is made public and
8375 renamed to PIC16_device, the same for variable Pics which is renamed

8390 Documenting changes from previous commits.
8391 * configure.in (version 1.56),
8392 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8393 when generating output files to configure the pic16 library,
8394 but now I've commented it out, since gputils aren't installed in the
8395 SF compile farm, so library won't compile
8397 * device/lib/Makefile.in (version 1.56): initially I've added in
8398 target 'all' the prerequestive 'model-pic16' so it compiled the
8399 pic16 library, but now I've commented it out for the same reasons
8401 * added targets 'model-pic16' and 'objects-pic16' to compile the
8403 * added target 'port-specific-objects-pic16' to handle the
8404 generated libraries and copy them into the build/ directory
8405 * added target 'clean-intermediate-pic16' to clean intermediate
8406 files into pic16 directory
8407 * in target 'installdirs' added line to create directory pic16 in
8408 the installation path
8410 * device/include/Makefile.in (version 1.11): in target 'install'
8411 added lines to copy all header files to installation path,
8412 * in target 'installdirs' added line create directory for pic16
8413 headers in the installation path

8428 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8429 option so that it actually works. Made it specific to the z80, since
8430 the gbz80 doesn't have these kinds of I/O ports.
8432 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8434 * device/include/z180.h,

8456 Mainly changes to support compilation of the device libraries
8457 * src/pic16/device.c: stack is allocated via symbol and not
8458 via literal number. The symbol is placed in the corresponding
8459 position of the data ram
8460 * (pic16_dump_section): relocatable and absolute uninitialized
8461 data are now emitted in sorted order to reduce section naming,
8462 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8463 weren't marked as being in the access bank,
8465 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8467 Added portion of GNU PIC Library under the directory
8468 device/include/pic16 and device/lib/pic16. These files
8469 contain the declarations of SFRs for the PIC18Fxx2 devices.
8470 The directory is initialized via configure from toplevel.
8472 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

8500 all over. Telling LaTeX to be less strict with word spacing
8501 to better keep the right margin. Changed some notes about
8502 maintainance of the ports in section 3.2.1 - is it OK like this?
8504 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8542 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8544 * src/pic16/peeph.def: all peepholes with movff are commented out,
8545 because there is a problem in the pcode peep optimizer,
8546 * src/pic16/ralloc.c: the register allocator can now reuse local

8687 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8689 * sdcc.spec: updated
8690 * device/include/Makefile.in: don't install CVS directories

8695 * src/ds390/gen.c (genRightShift): fixed bug #870788
8696 * src/SDCCast.c (decorateType): fixed bug #870781
8698 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8700 PIC16 port related changes:
8701 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8702 added variable stackPos,
8704 * gen.c: genCall, assignResultValue: added support for
8705 pushing/retrieving function parameters to/from stack,
8706 genFunction,genEndFunction: setup stack frame for the
8708 genAddrOf: will be changed according to bug 863624
8710 * added files genutils.c and genutils.h which contain gen*
8711 debugged and optimised functions extracted from gen.c
8713 * glue.c: added variable 'externs' which holds extern symbols,
8714 pic16emitRegularMap: is modified to properly handle relocatable
8715 symbols under the new scheme,
8716 pic16createInterruptVect: is modified
8717 pic16printPublics: is modified to emit 'global' assembler directives,
8718 added pic16_printExterns to print extern symbols,
8719 pic16glue: initializes stack/frame pointer in the beginning of
8720 the assembly output. Temporary hack, will be corrected later,
8721 because gplink yet does not support stack and SDCC does not
8722 yet support a type of crt0.o object to create the final binary.
8724 * Removed many lines that contain 8051 legacy code.
8725 * The code is finally placed under a 'code' directive.
8726 * Added port specific options.
8728 * _process_pragma: simplified since now we do not need *special*
8729 include file to define SFR registers. But a separate header
8730 will be needed. This will be developed later.
8731 * _pic16_parseOptions: added, parses port specific options:
8732 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8733 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8734 --preplace-udata-with=
8736 * _pic16_setDefaultOptions: modified to initialize section names,
8737 but hack is temporarly out of order since it needs improvement.
8738 * _pic16_genAssemblerPreamble: configuration words are emitted by
8739 their address instead of their name. This part is incomplete and
8740 supports only the 18Fxx2 devices. Other devices will emit an error
8741 during assembly since they do not contain the same set of config
8743 * _pic16_genIVT: is modified,
8745 * pcode.c: added definitions for some hardware registers that are needed
8747 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8748 All PCI entries are updated. Now LFSR is supported.
8749 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8750 * added pic16_newpCodeOpLit2 to support instructions with
8751 two literal arguments
8752 * pic16_pCode2str: corrected code that emits assembler instructions
8753 with two literal operands and those that have an access bit modifier
8754 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8755 this fixes a bug which caused some labels to be lost, when an
8756 assembler directive was added, i.e. banksel,
8757 * pic16_FixRegisterBanking: improved logic that causes the insertion
8759 * InlineFunction: functions that are called once, are not any more
8760 inlined. This can be a port option in the future,
8762 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8764 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8765 hold the corresponding uninitialized symbols,
8766 * pic16_allocProcessorRegister: registers have explicit marked the
8768 * pic16_allocInternalRegister: registers are explicit marked as
8770 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8771 processing list, so bit registers were lost,
8774 * ralloc.h: added field 'accessBank' and original symbol operand
8775 in register definition,
8776 * removed the field isMapped from register definition,
8778 ** Several functions have been removed from various sources:
8779 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8780 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8781 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8782 pic16_assignRelocatableRegisters
8784 ** others have been introduced:
8785 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8786 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8788 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8790 * support/scripts/inc2h.pl: changed definition of BIT_AT
8791 to emit 'sbit at' instead of 'bit at'. This was a request.
8793 PIC16 port related preliminary changes:
8794 * gen.c: prefixed function popRegFromString with
8795 pic16_ and all references to it corrected
8796 * pcode.c: all pic16_pc_* hardware registers prefixed
8797 with underscore (_),
8798 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8799 * ralloc.c: newReg(): when register is REG_SFR then
8800 set address to rIdx,
8801 pic16_allocProcessorRegister(): marks register wasUsed=0
8802 pic16_writeUsedRegs(): added a call to assign processor
8803 registers via pic16_assignFixedRegisters
8805 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8807 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8808 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8809 variables in unused register banks. Also the SSEG is placed
8810 wherever there is enough space for it, and IDATA can be anywhere
8811 in internal RAM. For now compile using -Wl-Y[stack_size].
8812 The mem file is different for this option as well, since it
8813 makes no sense of talking about DSEG lenght.
8815 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8817 * src/SDCClrange.c: fixed bug 869095 that caused segfault

9062 * src/SDCCast.c (decorateType): disabled a transformation I added in
9063 revision 1.188 (access to fields of a structure at an absolute address);
9064 it breaks with bitfields, extern declarations, and gcse analysis.
9065 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
9066 could be assigned through a pointer, so don't complain.

9174 xdata initialization slightly shorter
9176 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9823 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9824 fetching of the pointer
9825 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9826 copied from genNearPointerSet()
9827 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9828 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9829 If they pop r0/r1 they must be called in the opposite order than aopOp().
9830 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"

9842 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9844 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9845 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9846 type for bits was changed. It resulted in bit variables becoming
9847 global, which is not permitted in PIC 14 assembly output.
9849 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9851 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9864 A few small changes that speed up the peephole optimizer.
9868 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9870 Try to make the peephole optimizer smarter by maintaining
9871 an association between the assembly source code and the
9872 iCodes that originated them. Put this information to use
9873 with a new peephole rule condition "notVolatile" so that
9874 the rules can be aggressive yet still safe.
9879 * src/mcs51/peeph.def
9881 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9885 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9886 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9887 if the left or right operand symbols have the accuse flag set.
9889 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9891 Changed the type of the result of the ! (NOT) operator to char;
9892 previously it returned the same type as the source. This allows
9893 us to eliminate all the genFloatNot functions (all of its target
9894 implementations were very buggy) since !float can use the same
9897 * src/SDCCicode.c (ast2iCode): ! returns char
9898 * src/mcs51/gen.c (genNot, genNotFloat),
9899 * src/ds390/gen.c (genNot, genNotFloat),
9900 * src/z80/gen.c (genNot, genNotFloat),
9901 * src/pic/gen.c (genNot, genNotFloat),
9902 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
9904 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
9906 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9907 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9908 during interrupts. Ensure WSAVE is located at a shared bank address.
9909 2. Fixed page selection in some places
9910 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9911 the registers name strings.
9912 4. Fixed "signed / unsigned compare" compiler warnings.
9913 5. The PIC port manages its own allocation of the general purpose
9914 registers, but makes no attempt to reuse them. As a result when
9915 compiling it soon runs out of general purpose registers. Some
9916 additional code was added to the files pcode.c and device.c to walk
9917 through the function call tree and rename the registers so that they
9927 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9928 genPlus() & genMinus() when the result is the same as left or right

9934 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9936 Made bitfield a distinct type from bit so that bitfields
9937 convert as per ANSI C and bits retain their traditional
9938 boolean style behaviour. Implemented bitfield support in
9946 * src/ds390/gen.c: bit v bitfield split
9947 * src/z80/gen.c: New support for bitfields
9948 * support/regression/tests/bitfields.c: reenabled z80,
9951 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9953 Rules 246.x, 247.x relate to bitfields, the others speed up
9954 access to xdata mapped I/O devices.
9956 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9958 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9960 Cleaned up genPackBits and genUnpackBits and added two helper
9961 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9962 for literal assignments in genPackBits (thanks to Frieder for
9968 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9970 Fixed bug #748310 (pointer to function type mishandled when the
9971 function name is omitted). Also fixed a SIGSEGV when a function
9972 attribute (reentrant, etc) is used on a non-function or on a
9973 function but misplaced before the parameter list.
9975 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9977 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

10000 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10002 Made the constant following the "interrupt" keyword optional. If
10003 omitted, the function will not automatically be given an entry
10004 in the interrupt vector table (similar to #pragma NOIV, but
10005 less syntacticly kludgy). The interrupt number is also now
10006 range checked. Also fixed a bug in the high order bit example

10022 * src/SDCCsymt.c (computeType): literals are handled the same way as any
10024 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
10025 be re-activated by defining REDUCE_LITERALS)
10026 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10027 unsigned, but are signed by default
10028 * src/SDCCval.c (constVal): rearranged
10029 * src/SDCCval.c (valMod): preliminary fix
10030 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10070 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
10071 * src/SDCCval.c (constVal): changed default to signed; hex and octal
10072 constants are unsigned; added recognition of "u" flag for unsigned
10073 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
10074 * src/SDCCval.c (valDiv, valMod): fixed signdness

10483 the regression tests I'm not brave enough to enable 245.b, 245.c
10484 * doc/sdccman.lyx: added latex preamble for hyperref package.
10485 Using pdflatex this will give you a hyperlinked pdf file with

10536 added if/endif conditional macros to remove options help
10537 messages from optionsTable when a port is not configured, added
10538 support for the PIc16 port in the ports table, when executing
10539 the compiler with no port specified on command line, a default
10540 port is selected with the new macro DEFAULT_PORT which is
10541 defined in port.h, in setDefaultOptions() linkOptions is removed
10542 from initialization assignment, since now it is a set,
10543 parseCmdLine uses setParseWithComma for linkOptions, in
10544 linkEdit() linkOptions are accessed with new function indexSet()
10545 which returns the i'th item of a set variable. See SDCCset.c, in
10546 linkEdit() when calling buildCmdLine(), added linkOptions as
10547 last argument. Now users can pass arguments to gplink via the
10548 -Wl option, main() uses pic16glue() to glue up pic16 programs

10560 * src/pic16/glue.c: commented out some error producing lines
10561 * src/pic16/main.c: __config directives are commented out to stop
10562 gpasm complaining and test the linkage with gplink, _linkCmd and
10563 _asmCmd changed to be more gplink and gpasm friendly
10564 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10565 produced an error when parsed, peep rule 12 is added to utilize
10566 movff, but it is commented out since the pCode does not support
10567 yet a command with 2 address arguments
10569 2003-05-18 <johan AT balder>
10571 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11600 2003-01-06 <karl AT turbobit.com>
11601 * sim/ucsim/cmd.src/command.cc: fixed so "break xram r 0x7654" works again in
11604 2003-01-06 <johan AT balder>
11606 * src/SDCCicode.c: fixed array add
11608 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
11609 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
11610 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
11612 2003-01-04 <johan AT balder>
11614 * src/SDCCval.c (getNelements): fixed the initialized array of structures
11616 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11617 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
11619 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11620 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
11621 * support/regression/tests/bug-524697.c: fit mem usage into 8032
11623 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11624 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
11626 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11627 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11629 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11630 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11632 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11634 * in /sdcc/as/mcs51/ changed these files in order to create an
11635 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11636 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11637 following files to include the previous two files: aslink.dsp,
11638 Makefile.aslink, Makefile.bcc, and Makefile.in.
11640 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11641 .adb instead of .cdb
11643 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11645 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11646 value from option --iram-size.
11648 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11650 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11653 2002-09-18 <wiml AT hhhh.org>
11655 * SDCClrange.h: exposed setFromRange() and setToRange()
11656 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11657 packRegsForAccUse() (bug 542397)
11658 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11659 multiple times and emitting the fetch operations more than once
11660 added aopGetUsesAcc() function to allow binary operators to
11661 fetch their operands in the correct order; made genMinus() emit
11662 compact code for X = LITERAL - Y
11664 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11665 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11666 sprintf() in line 1267.
11668 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11669 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11672 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11673 Changes to aslink (All the changes are marked with 'JCF'):
11675 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11678 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11679 area BSEG. Also moves, if possible, the DATA area down into the internal
11680 ram so more space is available.
11682 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11685 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11686 not bytes. Function summary() which creates a memory usage summary
11687 file with extension .mem. Reports of overlaping stack and small stack
11688 size. If the space for the stack is less than 16 bytes aslink trows a
11691 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11692 the 8051. Option 'y' for memory summary output file.
11694 Changes to sdcc (All the changes are marked with 'JCF'):
11696 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11698 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11699 overlaying area for it (uses RegBankUsed[4]).
11701 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11702 bank zero as used by default. By default aslink locates the stack
11703 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11704 the creation of the .mem file. Delegates the allocation of data area
11705 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11706 the begining of the stack area to aslink.
11708 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11709 glue() in SDCCglue.c creates an area for it.
11711 2002-09-03 Borut Razem <borut.razem AT siol.net>
11712 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11713 sdcc/src/pic/glue.c:
11714 introduced atexit() handler for teporay files removal in case of
11715 errors, assertions, ...
11717 2002-08-29 Borut Razem <borut.razem AT siol.net>
11718 * sdcc/support/cpp2/auto-host_vc_in.h:
11719 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11720 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11721 Maybe there is a similar problem with BORLANDC? It should be checked!
11723 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11724 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11725 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11726 was not executed, and the compiler (cl) launched a warning:
11727 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11729 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11730 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11732 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11733 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11735 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11736 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11737 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11738 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11739 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11740 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11741 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11742 - added Release configuration in VS projects
11743 - review of compiler an linker options
11744 - VC .exe files are generated in bin_vc directory, not to interfere
11745 with binaries generated from other projects (cygwin, mingw, bcc ...)
11747 * sdcc/src/yacc.dsp: added
11749 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11750 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11751 and insert the version number definitions from .version
11753 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11755 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11756 added - genarate auto-host.h using auto-host_vc_in.h as template
11759 removed from CVS, generated automatically
11761 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11762 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11764 2002-08-11 Borut Razem <borut.razem AT siol.net>
11765 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11767 2002-08-10 Borut Razem <borut.razem AT siol.net>
11768 * src/SDCCmain.c (main):
11769 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11770 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11771 The consequence was that some temporary files were not removed.
11774 unification of code in functions tempfilename() and tempfile():
11775 function tempnam() is defined in Visual Studio 6.0 and .NET
11777 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11779 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11780 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11781 - removed compiler command line option /WX: Treats all warnings as errors
11782 - update a list of source files, included into the project
11784 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11785 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11786 changed project type to Generic Project so that can be correcly converted to VS.NET project
11788 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11790 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11792 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11794 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11795 added return 0 statements after assert() to make compiler happy
11797 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11798 added newline in the def file to keep MSC compiler satisfied
11800 * sdcc/src/z80/gen.c:
11801 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11802 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11803 - solved MSC error in function aopDump()
11805 * sdcc_vc.h: define PREFIX as "\\sdcc"
11807 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11808 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
11810 2002-06-22 Scott Dattalo <scott AT dattalo.com>
11811 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11812 - Rewrote the register banking algorithm.
11813 - Added pCode live-range analysis to registers (for now, only non-used and
11814 singly-used registers optimized away)
11816 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11818 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.

11841 * src/z80/main.c: Added force callee saves for jaune.
11843 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11845 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11847 2002-03-28 Johan Knol <johan AT balder>
11849 * src/SDCCval.c: fixed bug #532436
11851 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11853 Added "char *Processor" field to the port structure.
11856 Added -p option. Allows port dependent processor to be specified.
11859 Initialized the new field char *Processor field to NULL in all ports
11862 Compiler generated registers for interrupt context saving
11863 were not getting allocated.
11865 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11868 Fixed left shift. Will promote the left side of a left shift
11869 if a) left shifting more than size of operand or b) when assigned
11870 to something size > size of left side
11872 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11874 tons of changes. Register allocation has been
11875 rewritten. Added customization for the various PICs. Flow
11876 analysis is restructured. ...
11878 * src/pic/device.h:
11881 * src/pic/device.c:
11882 Added. device.c is a PIC port hack to accomodate variations
11885 2002-03-13 Michael Hope <michaelh AT vroom>
11887 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11889 2002-03-04 johanknol <johanknol AT manik>
11891 * /src/SDCCval.c: fixed
11893 const unsigned char arr[][2] = { { 0, 1 } };

11980 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11982 * sdcc/src/SDCCloop.c:
11983 Previous fix was not good. basic blocks that have "break" or "return" are
11984 not really partof a loop , but live ranges used in these blocks should
11985 be live thru the entire loop, so set partOfLoop but don't add them to
11988 2002-02-21 <johan AT FRIJA>
11990 * src/SDCCcse.c: fixed bug #514308
11992 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
11995 Fixed BUG #519583. If a conditional block ended in a return/break
11996 statement inside a loop, it was not being considered part of the loop.
11998 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
12000 2002-02-10 Karl Bongers <karl AT turbobit.com>

12006 * device/examples/test2.c:
12007 Fix bug, "red" variable not being initialized(compiler complained).
12009 * device/examples/Makefile, examples/test3.c:
12010 Add Makefile in device/examples folder, compiles test3.c
12011 for use as a multiple module SDCDB test case.
12013 * sim/ucsim/cmd.src/cmdset.cc:
12014 Took out debug printfs in ucsim "next" command.
12016 * sim/ucsim/xa.src:
12017 Karl and Johan start ucsim XA support. Most dissassembly working,
12018 about 75% emulation done(plenty of work remaining).
12020 * sim/ucsim/z80.src:
12021 Add Z80 support to ucsim, add test-ucz80 regression test,
12022 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
12023 Notice z80 compiler fails on examples/test3.c/crc code.
12025 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>

12039 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
12040 1) handle multiple send & receives from register bank1
12041 2) ralloc can now allocate DPTR1 to some liveRanges
12043 * src/SDCCsymt.c, src/SDCCsymt.h:
12044 changes to handle multiple sends & receives
12046 * src/SDCCptropt.h:
12047 added some pointer arithmetic optimization
12049 * src/SDCCptropt.c:

12051 called from anywhere (will get this working shortly)
12053 * src/SDCCopt.c: fixed for multiple sends & receives
12056 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
12057 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
12058 set preprocessor defines (depending on options)
12060 * src/SDCCicode.c, src/SDCCicode.h:
12061 changes made to handle multiple sends & receives
12064 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
