1708 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1710 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1711 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1713 One basic decision: e.g. src/clean.mk includes further files. In order
1714 to make this work there are two solutions:
1715 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1716 run configure on them. This way they can use
1717 'include $(srcdir)/port-clean.mk'
1718 - always include clean.mk by the Makefile at the same level. To avoid
1719 that `make clean` tries to include and build Makefile.dep the
1720 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1721 implemented, because now even `make uninstall` doesn't create
1722 Makefile.in. clean.mk could be eliminated by pasting it in
1725 * debugger/mcs51/Makefile.in: build own objects from library sources
1726 (SLIB, SDCC) in current directory
1728 * configure, configure.in: renamed --disable-device-lib-build in
1729 --disable-device-lib; added --enable-doc, the required tools are
1730 searched by configure; added result message; the toolchain for the
1731 belonging ports are now only built, if the port is enabled.
1733 * support/regression/*: all output is written in directory gen, because
1734 the fwk and ports directories don't livet in the build tree using vpath
1736 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1737 --disable-device-lib, added --enable-doc, added section VPATH
1739 * sim/ucsim/configure.in,
1740 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1741 z80 are enabled by default
1743 2006-04-24 Raphael Neider <rneider AT web.de>
1745 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1746 to config word, "pic14_"-prefixed some extern functions
1747 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1748 config word has been found
1749 * src/pic/device.h: added prototypes
1750 * src/pic/pcode.c: added "pic14_"-prefix where needed
1751 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1753 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
1755 (pic14emitRegularMap): ignore config words,
1756 (pic14createInterruptVect): moved generating __config directives away
1757 (picglue): have __config directives emitted
1759 2006-04-24 Borut Razem <borut.razem AT siol.net>
1761 * doc/Makefile: sync with nightly build makefile
1763 2006-04-24 Raphael Neider <rneider AT web.de>
1765 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
1766 registers that have not been assigned proper liveranges,
1767 fixes #1469504 and #1474602,
1768 (pCodeRegOptimizeRegUsage): fixed typo in comment
1770 2006-04-24 Borut Razem <borut.razem AT siol.net>
1772 * device/examples/main8051.c: deleted - it was removed from CVS
1773 24.mar.2000 and after that modified 18.feb.2001, so it reappered
1774 after the transition to Subversion
1775 * src/SDCCalloc.h: deleted - it was removed from CVS
1776 3.feb.2001 and after that modified 18.feb.2001, so it reappered
1777 after the transition to Subversion
1778 * sim/ucsim/cpu.gif, sim/ucsim/interrupt.gif, sim/ucsim/new.gif,
1779 sim/ucsim/serial1.gif, sim/ucsim/serial2.gif,

2016 and enabled nesting of critical functions though not for gbz80
2017 (genCritical, genEndCritical): added functions
2018 (genZ80Code): added cases for CRITICAL and ENDCRITICAL

2036 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2038 * src/.version: increased version number to 2.5.5
2039 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2040 linking is done manually in pic16 port's _linkEdit,
2041 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2042 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2043 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2044 allocate asmop as AOP_ACC,
2045 (aopForRemat): added parameter 'bool result' in function declaration,
2046 (pic16_aopGet): return AOP_ACC when accessing WREG,

2058 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2059 call to allocReg, not by manually allocating a new one,
2060 (pic16_assignRegisters): now before going through the register
2061 allocating functions mark all registers as free. This eliminates some
2062 side effects resulting from peephole parser done earlier in the backbone
2064 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

2122 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2123 which dumps before the function entry point a data byte which represents
2124 the number of the local variables used by the specified function, added
2125 'xinst' for initial support for Extended Instruction Support,
2126 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2127 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2128 port->fun_prefix anymore (may change later),
2129 (genFunction, genEndFunction): do not store/restore local registers for
2130 _main (this should take care the --main-return command line option in
2132 (genOr): removed some legacy pic-port instructions,
2133 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2134 performing operations with SFR's causes data to be written more than
2135 once to each SFR. Perhaps SFRs should be handled in special cases...
2136 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2138 * src/pic16/main.c (_process_pragma): stack bound checking did not take

2143 (deassignLRs): *** perhaps the most important change, old 'for' code
2144 (commented out for reference), didn't account for some registers which
2145 were left marked 'not free' after a pointer operation. The change
2146 reduces register usage a lot in some cases
2148 2006-03-04 Borut Razem <borut.razem AT siol.net>

4422 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4423 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4424 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4425 always available in leading double underscore form. The C99 support is
4426 mostly missing, but it's a start.
4427 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4428 reserved identifier "__data".

4506 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4508 * device/lib/printf_large.c: removed inline assembly for portability and
4509 readability. Use printf_fast if speed or size are more important.
4510 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4511 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4513 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4515 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4516 prevent compiler warning
4518 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4520 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4521 moved to level 0 and declared as static. Also they are explicit
4522 placed in access bank. This was necessery because some times they
4523 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4524 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4525 optimizations. Currently only compare to unsigned char is implemented,
4526 * src/pic16/gen.c: added fReturnIdx array,
4527 * (struct resolvedIfx) is moved to gen.h and made public,
4528 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4529 * (aopForSym): added an optimization to directly store in stack of
4530 the operand of a SEND iCode,
4531 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4532 but as registers instead (AOP_REG) using the fReturnIdx array,
4533 * (pic16_freeAsmop): remove the freed register from the
4534 _G.sregsAlloc field,
4535 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4536 a compare of 'WREG',
4537 * (pic16_popGetTempRegCond): changed function prototype, now
4538 function takes also a bitVector argument v which holds the current
4539 set of registers that are allocated for stack access by aopForSym,
4540 registers allocated in aopForSym for accessing stack symbols are not
4541 any more part of the functions usedRegs field,
4542 * (genCall): some times aopOp is called for a stack variable to be
4543 send, aopForSym might perform the push, if this is true make sure
4544 that genCall doesn't push the variable twice by testing _G.resDirect,
4545 * (genFunction): changed testing for unspecified interrupt number
4546 from 256 to INTNO_UNSPEC,
4547 * modified selection scheme of frame pointer generation. Previously
4548 if function did use local registers a frame pointer was generated,
4549 now a frame pointer is generated only if function has arguments
4550 (that need PLUSW2 register access), or has stack arguments, or the
4551 compiler is not instructed to omit the frame pointer,
4552 * (genEndFunction): before restoring local registers that were saved
4553 in the function preamble, also restore the registers that *might*
4554 have been allocated for stack access,
4555 * (genRet): removed some old comments,
4556 * (genCmp, the active (RN's) version): added a call to the
4557 pic16_genCmp_special function to perform the compare with a more
4558 robust and optimized way,
4559 * (genInline): a feature has been added in inline code generation,
4560 which allows a wildcard variable substitution when writing inline
4561 assembly. Code is incomplete and experimental therefore undocumented,
4562 * (genCast): changed order of aopOp for result and right to allow
4563 aopForSym to directly load the result if possible,
4564 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4565 perform an optimized compare on some selected special occasions,
4566 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4567 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4568 generate an IVT any more,
4569 * src/pic16/main.c (pic16_optionsTable): added command line option
4571 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4572 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4574 * src/pic16/NOTES: Raphael Neider added in list of active developers
4575 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4576 jumptable_end to prevent bug #,
4577 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4578 inCond and outCond fields,
4579 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4580 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4581 turn off register spilling,
4582 * (packRegsForOneUse): synced with other ports' versions although it
4583 is not used currently,
4584 * (pic16_packRegisters): added an optimization while reading
4585 structure bitfields, some registers may be saved (malloc code is
4586 decreased by 80 bytes)
4588 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4590 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4591 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4592 this can be optimized more?
4594 2005-03-10 Raphael Neider <rneider AT web.de>
4596 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4597 genNearPointerGet): (hopefully) fixed access to bitfields via
4598 pointers (p->bitN = x; and x = p->bitN; failed)

5232 Adding support for replacing ljmps with sjmps in jumptables
5233 generated for switch statements. For now you need to set the
5234 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5235 Now 4 algorithms for mcs51 jumptable generation are used:
5236 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5237 addresses loaded pc-relative for up to 112 cases and stack-pushing
5238 target addresses loaded with offset from dptr for up to 256 cases.

5265 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
5266 to call when a stack overflow occurs,
5267 * (malloc.h): added CVS Id tag,
5268 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5270 * added libc directory. The current version of LibC contains string
5271 functions, ctype functions and macros and some functions of the
5272 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5273 be extensively tested in the future. Standard disclaimer here.
5274 Library is not automatically build yet. But one can build it by
5275 invoking 'make' inside the libc directory.
5276 * added ADC library under libio. Preliminary version yet.
5278 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

5285 * (genUminusFloat): fixed for pic16, ported code from mcs51,
5286 * (pic16_storeForReturn): optimized return of 0,
5287 * (genCmp): experimental code for new genCmp which uses PIC18's
5288 special compare&skip instructions. Initial tests fail some times
5289 with variables grater than 1 byte in size, so new code is disabled,
5290 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5292 * (genCast): began a fix to optimize the casting of a bit to another
5293 bit, now assigning a bitfield to another bitfield will fail, sorry,
5294 * src/pic16/main.c: disabled the use of lr-support feature,
5295 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

5298 bits with offset (case PO_GPR_BIT),
5299 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
5301 * (isBankInstruction): modified to return 0 for no banking instruction,
5302 and 1 for banking instruction,
5303 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5304 caused stop processing pCodes after a inline assembly block,
5305 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
5306 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
5307 registers when it shouldn't,
5308 * src/pic16/ralloc.c (allocReg): add preliminary support for
5309 supporting a limited set of temporary registers,
5311 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5313 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
5314 genDataPointerSet): ensure assignments always copy in MSB to LSB
5316 (loadRegFromAop): recognize CLRH optimization,
5317 (genFunction): optimize RECEIVE iCodes in reentrant functions
5319 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5321 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

8271 code / RAM are in the same page / bank. This means the linker can
8272 safely allocate code/RAM of separate ASM files to different pages/banks.
8273 * doc/sdccman.lyx: added Slade's tips
8274 * src/mcs51/peeph.def: fixed bug #880768

8286 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
8287 strtof is not part of C89 and isn't included with Mac OS X.
8289 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8291 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,
8292 shiftL2Left2Result): fixed bug #879326
8293 (genAnd, genOr, genXor): fixed bug when result was of type AOP_CRY

8316 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8318 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8319 loaded with the linker search paths (-L arguments) and the libraries
8320 to be linked with the current source (-l arguments). Changes
8321 currently will affect only the pic16 port.
8322 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8323 include path the port specific paths and port specific libraries,
8324 * gplink command now contains the $3 argument,
8325 * src/pic16/device.h,
8326 * src/pic16/device.c,: structure PIC_device is made public and
8327 renamed to PIC16_device, the same for variable Pics which is renamed
8328 to Pics16. Updated all references to them.
8329 * src/pic16/glue.c (pic16glue): corrected bug with code
8330 initialization which bypassed the variable initializations block.

8340 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
8342 Documenting changes from previous commits.
8343 * configure.in (version 1.56),
8344 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8345 when generating output files to configure the pic16 library,
8346 but now I've commented it out, since gputils aren't installed in the
8347 SF compile farm, so library won't compile
8349 * device/lib/Makefile.in (version 1.56): initially I've added in
8350 target 'all' the prerequestive 'model-pic16' so it compiled the
8351 pic16 library, but now I've commented it out for the same reasons
8353 * added targets 'model-pic16' and 'objects-pic16' to compile the
8355 * added target 'port-specific-objects-pic16' to handle the
8356 generated libraries and copy them into the build/ directory
8357 * added target 'clean-intermediate-pic16' to clean intermediate
8358 files into pic16 directory
8359 * in target 'installdirs' added line to create directory pic16 in
8360 the installation path
8362 * device/include/Makefile.in (version 1.11): in target 'install'
8363 added lines to copy all header files to installation path,
8364 * in target 'installdirs' added line create directory for pic16
8365 headers in the installation path

8380 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8381 option so that it actually works. Made it specific to the z80, since
8382 the gbz80 doesn't have these kinds of I/O ports.
8384 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8386 * device/include/z180.h,

8408 Mainly changes to support compilation of the device libraries
8409 * src/pic16/device.c: stack is allocated via symbol and not
8410 via literal number. The symbol is placed in the corresponding
8411 position of the data ram
8412 * (pic16_dump_section): relocatable and absolute uninitialized
8413 data are now emitted in sorted order to reduce section naming,
8414 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8415 weren't marked as being in the access bank,
8417 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8419 Added portion of GNU PIC Library under the directory
8420 device/include/pic16 and device/lib/pic16. These files
8421 contain the declarations of SFRs for the PIC18Fxx2 devices.
8422 The directory is initialized via configure from toplevel.
8424 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
8426 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
8427 the spilllocations to be compared correctly

8436 doc/sdccman.lyx: upper case pragmas are deprecated
8438 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
8440 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
8441 in simpler and even better code
8443 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
8445 * src/SDCCicode.c (operandOperation): fixed bug #874819

8452 all over. Telling LaTeX to be less strict with word spacing
8453 to better keep the right margin. Changed some notes about
8454 maintainance of the ports in section 3.2.1 - is it OK like this?
8456 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8494 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8496 * src/pic16/peeph.def: all peepholes with movff are commented out,
8497 because there is a problem in the pcode peep optimizer,
8498 * src/pic16/ralloc.c: the register allocator can now reuse local

8613 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8615 A python script to validate compiler diagnostic messages. It can be
8616 used to verify that sdcc complains about bad c source code and
8617 gives a good location of the error.
8618 * support/valdiag/Makefile,
8619 * support/valdiag/valdiag.py,
8620 * support/valdiag/tests/*

8650 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8652 PIC16 port related changes:
8653 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8654 added variable stackPos,
8656 * gen.c: genCall, assignResultValue: added support for
8657 pushing/retrieving function parameters to/from stack,
8658 genFunction,genEndFunction: setup stack frame for the
8660 genAddrOf: will be changed according to bug 863624
8662 * added files genutils.c and genutils.h which contain gen*
8663 debugged and optimised functions extracted from gen.c
8665 * glue.c: added variable 'externs' which holds extern symbols,
8666 pic16emitRegularMap: is modified to properly handle relocatable
8667 symbols under the new scheme,
8668 pic16createInterruptVect: is modified
8669 pic16printPublics: is modified to emit 'global' assembler directives,
8670 added pic16_printExterns to print extern symbols,
8671 pic16glue: initializes stack/frame pointer in the beginning of
8672 the assembly output. Temporary hack, will be corrected later,
8673 because gplink yet does not support stack and SDCC does not
8674 yet support a type of crt0.o object to create the final binary.
8676 * Removed many lines that contain 8051 legacy code.
8677 * The code is finally placed under a 'code' directive.
8678 * Added port specific options.
8680 * _process_pragma: simplified since now we do not need *special*
8681 include file to define SFR registers. But a separate header
8682 will be needed. This will be developed later.
8683 * _pic16_parseOptions: added, parses port specific options:
8684 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8685 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8686 --preplace-udata-with=
8688 * _pic16_setDefaultOptions: modified to initialize section names,
8689 but hack is temporarly out of order since it needs improvement.
8690 * _pic16_genAssemblerPreamble: configuration words are emitted by
8691 their address instead of their name. This part is incomplete and
8692 supports only the 18Fxx2 devices. Other devices will emit an error
8693 during assembly since they do not contain the same set of config
8695 * _pic16_genIVT: is modified,
8697 * pcode.c: added definitions for some hardware registers that are needed
8699 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8700 All PCI entries are updated. Now LFSR is supported.
8701 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8702 * added pic16_newpCodeOpLit2 to support instructions with
8703 two literal arguments
8704 * pic16_pCode2str: corrected code that emits assembler instructions
8705 with two literal operands and those that have an access bit modifier
8706 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8707 this fixes a bug which caused some labels to be lost, when an
8708 assembler directive was added, i.e. banksel,
8709 * pic16_FixRegisterBanking: improved logic that causes the insertion
8711 * InlineFunction: functions that are called once, are not any more
8712 inlined. This can be a port option in the future,
8714 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8716 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8717 hold the corresponding uninitialized symbols,
8718 * pic16_allocProcessorRegister: registers have explicit marked the
8720 * pic16_allocInternalRegister: registers are explicit marked as
8722 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8723 processing list, so bit registers were lost,
8726 * ralloc.h: added field 'accessBank' and original symbol operand
8727 in register definition,
8728 * removed the field isMapped from register definition,
8730 ** Several functions have been removed from various sources:
8731 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8732 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8733 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8734 pic16_assignRelocatableRegisters
8736 ** others have been introduced:
8737 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8738 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8740 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8742 * support/scripts/inc2h.pl: changed definition of BIT_AT
8743 to emit 'sbit at' instead of 'bit at'. This was a request.
8745 PIC16 port related preliminary changes:
8746 * gen.c: prefixed function popRegFromString with
8747 pic16_ and all references to it corrected
8748 * pcode.c: all pic16_pc_* hardware registers prefixed
8749 with underscore (_),
8750 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8751 * ralloc.c: newReg(): when register is REG_SFR then
8752 set address to rIdx,
8753 pic16_allocProcessorRegister(): marks register wasUsed=0
8754 pic16_writeUsedRegs(): added a call to assign processor
8755 registers via pic16_assignFixedRegisters
8757 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8759 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8760 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8761 variables in unused register banks. Also the SSEG is placed
8762 wherever there is enough space for it, and IDATA can be anywhere
8763 in internal RAM. For now compile using -Wl-Y[stack_size].
8764 The mem file is different for this option as well, since it
8765 makes no sense of talking about DSEG lenght.
8767 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>

9016 it breaks with bitfields, extern declarations, and gcse analysis.

9753 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
9755 * device/lib/_mullong.c: replaced int by short for gcc
9757 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9759 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
9760 and JUMPTABLE iCodes properly now (worked by accident before)
9761 * src/mcs51/gen.c (leftRightUseAcc),
9762 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
9763 iCode properly now. Use getSize instead of nRegs since a & b
9764 aren't part of the nRegs tally.
9766 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
9768 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
9769 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
9770 before instructions that use the _STATUS register
9772 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
9774 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9775 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9776 fetching of the pointer
9777 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9778 copied from genNearPointerSet()
9779 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9780 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9781 If they pop r0/r1 they must be called in the opposite order than aopOp().
9782 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9783 (resp. --stack-auto), prepared for --xstack

9789 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9791 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
9792 these ports have their own __sdcc_external_start()
9794 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9796 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9797 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9798 type for bits was changed. It resulted in bit variables becoming
9799 global, which is not permitted in PIC 14 assembly output.
9801 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9803 * doc/sdccman.lyx: various additions and updates. Rearranged sections
9805 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9807 Z80 and MCS51 linkers complaint if a public symbol is defined

9816 A few small changes that speed up the peephole optimizer.
9820 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9822 Try to make the peephole optimizer smarter by maintaining
9823 an association between the assembly source code and the
9824 iCodes that originated them. Put this information to use
9825 with a new peephole rule condition "notVolatile" so that
9826 the rules can be aggressive yet still safe.
9831 * src/mcs51/peeph.def
9833 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9837 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9838 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9839 if the left or right operand symbols have the accuse flag set.
9841 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9843 Changed the type of the result of the ! (NOT) operator to char;
9844 previously it returned the same type as the source. This allows
9845 us to eliminate all the genFloatNot functions (all of its target
9846 implementations were very buggy) since !float can use the same
9849 * src/SDCCicode.c (ast2iCode): ! returns char
9850 * src/mcs51/gen.c (genNot, genNotFloat),
9851 * src/ds390/gen.c (genNot, genNotFloat),
9852 * src/z80/gen.c (genNot, genNotFloat),
9853 * src/pic/gen.c (genNot, genNotFloat),
9854 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
9856 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
9858 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9859 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9860 during interrupts. Ensure WSAVE is located at a shared bank address.
9861 2. Fixed page selection in some places
9862 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9863 the registers name strings.
9864 4. Fixed "signed / unsigned compare" compiler warnings.
9865 5. The PIC port manages its own allocation of the general purpose
9866 registers, but makes no attempt to reuse them. As a result when
9867 compiling it soon runs out of general purpose registers. Some
9868 additional code was added to the files pcode.c and device.c to walk
9869 through the function call tree and rename the registers so that they
9879 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9880 genPlus() & genMinus() when the result is the same as left or right

9886 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9888 Made bitfield a distinct type from bit so that bitfields
9889 convert as per ANSI C and bits retain their traditional
9890 boolean style behaviour. Implemented bitfield support in
9898 * src/ds390/gen.c: bit v bitfield split
9899 * src/z80/gen.c: New support for bitfields
9900 * support/regression/tests/bitfields.c: reenabled z80,
9903 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9905 Rules 246.x, 247.x relate to bitfields, the others speed up
9906 access to xdata mapped I/O devices.
9908 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9910 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9912 Cleaned up genPackBits and genUnpackBits and added two helper
9913 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9914 for literal assignments in genPackBits (thanks to Frieder for
9920 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9922 Fixed bug #748310 (pointer to function type mishandled when the
9923 function name is omitted). Also fixed a SIGSEGV when a function
9924 attribute (reentrant, etc) is used on a non-function or on a
9925 function but misplaced before the parameter list.
9927 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9929 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9930 * support/Util/SDCCerr.h,
9931 * support/Util/SDCCerr.c: Added func attr misuse error msg
9933 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
9935 Fixed bug #787649 by anonymous
9936 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

9952 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9954 Made the constant following the "interrupt" keyword optional. If
9955 omitted, the function will not automatically be given an entry
9956 in the interrupt vector table (similar to #pragma NOIV, but
9957 less syntacticly kludgy). The interrupt number is also now
9958 range checked. Also fixed a bug in the high order bit example
9965 * support/Util/SDCCerr.c
9966 * support/Util/SDCCerr.h
9969 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

9972 * src/SDCCicode.c (operandOperation): rewritten some ops
9973 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9974 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9976 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9977 be re-activated by defining REDUCE_LITERALS)
9978 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9979 unsigned, but are signed by default
9980 * src/SDCCval.c (constVal): rearranged
9981 * src/SDCCval.c (valMod): preliminary fix
9982 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10024 constants are unsigned; added recognition of "u" flag for unsigned
10025 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
10026 * src/SDCCval.c (valDiv, valMod): fixed signdness

10434 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
10435 the regression tests I'm not brave enough to enable 245.b, 245.c
10436 * doc/sdccman.lyx: added latex preamble for hyperref package.
10437 Using pdflatex this will give you a hyperlinked pdf file with

10479 it can be defined with CFLAGS when running configure
10480 * src/SDCCmain.c: fixed compiling + linking with object files
10482 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

10487 * src/SDCCmain.c: linkOptions is changed to set *,
10488 added if/endif conditional macros to remove options help
10489 messages from optionsTable when a port is not configured, added
10490 support for the PIc16 port in the ports table, when executing
10491 the compiler with no port specified on command line, a default
10492 port is selected with the new macro DEFAULT_PORT which is
10493 defined in port.h, in setDefaultOptions() linkOptions is removed
10494 from initialization assignment, since now it is a set,
10495 parseCmdLine uses setParseWithComma for linkOptions, in
10496 linkEdit() linkOptions are accessed with new function indexSet()
10497 which returns the i'th item of a set variable. See SDCCset.c, in
10498 linkEdit() when calling buildCmdLine(), added linkOptions as
10499 last argument. Now users can pass arguments to gplink via the
10500 -Wl option, main() uses pic16glue() to glue up pic16 programs

10512 * src/pic16/glue.c: commented out some error producing lines
10513 * src/pic16/main.c: __config directives are commented out to stop
10514 gpasm complaining and test the linkage with gplink, _linkCmd and
10515 _asmCmd changed to be more gplink and gpasm friendly
10516 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10517 produced an error when parsed, peep rule 12 is added to utilize
10518 movff, but it is commented out since the pCode does not support
10519 yet a command with 2 address arguments
10521 2003-05-18 <johan AT balder>
10523 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11588 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11589 following files to include the previous two files: aslink.dsp,
11590 Makefile.aslink, Makefile.bcc, and Makefile.in.
11592 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11593 .adb instead of .cdb
11595 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11597 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11598 value from option --iram-size.
11600 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11602 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11605 2002-09-18 <wiml AT hhhh.org>
11607 * SDCClrange.h: exposed setFromRange() and setToRange()
11608 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11609 packRegsForAccUse() (bug 542397)
11610 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11611 multiple times and emitting the fetch operations more than once
11612 added aopGetUsesAcc() function to allow binary operators to
11613 fetch their operands in the correct order; made genMinus() emit
11614 compact code for X = LITERAL - Y
11616 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11617 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11618 sprintf() in line 1267.
11620 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11621 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11624 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11625 Changes to aslink (All the changes are marked with 'JCF'):
11627 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11630 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11631 area BSEG. Also moves, if possible, the DATA area down into the internal
11632 ram so more space is available.
11634 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11637 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11638 not bytes. Function summary() which creates a memory usage summary
11639 file with extension .mem. Reports of overlaping stack and small stack
11640 size. If the space for the stack is less than 16 bytes aslink trows a
11643 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11644 the 8051. Option 'y' for memory summary output file.
11646 Changes to sdcc (All the changes are marked with 'JCF'):
11648 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11650 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11651 overlaying area for it (uses RegBankUsed[4]).
11653 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11654 bank zero as used by default. By default aslink locates the stack
11655 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11656 the creation of the .mem file. Delegates the allocation of data area
11657 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11658 the begining of the stack area to aslink.
11660 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11661 glue() in SDCCglue.c creates an area for it.
11663 2002-09-03 Borut Razem <borut.razem AT siol.net>
11664 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11665 sdcc/src/pic/glue.c:
11666 introduced atexit() handler for teporay files removal in case of
11667 errors, assertions, ...
11669 2002-08-29 Borut Razem <borut.razem AT siol.net>
11670 * sdcc/support/cpp2/auto-host_vc_in.h:
11671 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11672 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11673 Maybe there is a similar problem with BORLANDC? It should be checked!
11675 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11676 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11677 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11678 was not executed, and the compiler (cl) launched a warning:
11679 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11681 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11682 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11684 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11685 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11687 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11688 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11689 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11690 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11691 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11692 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11693 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11694 - added Release configuration in VS projects
11695 - review of compiler an linker options
11696 - VC .exe files are generated in bin_vc directory, not to interfere
11697 with binaries generated from other projects (cygwin, mingw, bcc ...)
11699 * sdcc/src/yacc.dsp: added
11701 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11702 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11703 and insert the version number definitions from .version
11705 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11707 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11708 added - genarate auto-host.h using auto-host_vc_in.h as template
11711 removed from CVS, generated automatically
11713 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11714 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11716 2002-08-11 Borut Razem <borut.razem AT siol.net>
11717 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11719 2002-08-10 Borut Razem <borut.razem AT siol.net>
11720 * src/SDCCmain.c (main):
11721 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11722 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11723 The consequence was that some temporary files were not removed.
11726 unification of code in functions tempfilename() and tempfile():
11727 function tempnam() is defined in Visual Studio 6.0 and .NET
11729 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11731 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11732 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11733 - removed compiler command line option /WX: Treats all warnings as errors
11734 - update a list of source files, included into the project
11736 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11737 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11738 changed project type to Generic Project so that can be correcly converted to VS.NET project
11740 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11742 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11744 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11746 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11747 added return 0 statements after assert() to make compiler happy
11749 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11750 added newline in the def file to keep MSC compiler satisfied
11752 * sdcc/src/z80/gen.c:
11753 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11754 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11755 - solved MSC error in function aopDump()
11757 * sdcc_vc.h: define PREFIX as "\\sdcc"
11759 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11760 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11763 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11764 - Rewrote the register banking algorithm.
11765 - Added pCode live-range analysis to registers (for now, only non-used and
11766 singly-used registers optimized away)
11768 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11770 * 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.

11795 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11797 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11799 2002-03-28 Johan Knol <johan AT balder>
11801 * src/SDCCval.c: fixed bug #532436
11803 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11805 Added "char *Processor" field to the port structure.
11808 Added -p option. Allows port dependent processor to be specified.
11811 Initialized the new field char *Processor field to NULL in all ports
11814 Compiler generated registers for interrupt context saving
11815 were not getting allocated.
11817 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11820 Fixed left shift. Will promote the left side of a left shift
11821 if a) left shifting more than size of operand or b) when assigned
11822 to something size > size of left side
11824 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11826 tons of changes. Register allocation has been

11828 analysis is restructured. ...
11830 * src/pic/device.h:
11833 * src/pic/device.c:
11834 Added. device.c is a PIC port hack to accomodate variations
11837 2002-03-13 Michael Hope <michaelh AT vroom>
11839 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11841 2002-03-04 johanknol <johanknol AT manik>
11843 * /src/SDCCval.c: fixed
11845 const unsigned char arr[][2] = { { 0, 1 } };

11932 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11934 * sdcc/src/SDCCloop.c:
11935 Previous fix was not good. basic blocks that have "break" or "return" are
11936 not really partof a loop , but live ranges used in these blocks should
11937 be live thru the entire loop, so set partOfLoop but don't add them to
11940 2002-02-21 <johan AT FRIJA>
11942 * src/SDCCcse.c: fixed bug #514308
11944 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
11947 Fixed BUG #519583. If a conditional block ended in a return/break
11948 statement inside a loop, it was not being considered part of the loop.
11950 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
11952 2002-02-10 Karl Bongers <karl AT turbobit.com>
