1737 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1739 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1740 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1742 One basic decision: e.g. src/clean.mk includes further files. In order
1743 to make this work there are two solutions:
1744 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1745 run configure on them. This way they can use
1746 'include $(srcdir)/port-clean.mk'
1747 - always include clean.mk by the Makefile at the same level. To avoid
1748 that `make clean` tries to include and build Makefile.dep the
1749 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1750 implemented, because now even `make uninstall` doesn't create
1751 Makefile.in. clean.mk could be eliminated by pasting it in
1754 * debugger/mcs51/Makefile.in: build own objects from library sources
1755 (SLIB, SDCC) in current directory
1757 * configure, configure.in: renamed --disable-device-lib-build in
1758 --disable-device-lib; added --enable-doc, the required tools are
1759 searched by configure; added result message; the toolchain for the
1760 belonging ports are now only built, if the port is enabled.
1762 * support/regression/*: all output is written in directory gen, because
1763 the fwk and ports directories don't livet in the build tree using vpath
1765 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1766 --disable-device-lib, added --enable-doc, added section VPATH
1768 * sim/ucsim/configure.in,
1769 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1770 z80 are enabled by default
1772 2006-04-24 Raphael Neider <rneider AT web.de>
1774 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1775 to config word, "pic14_"-prefixed some extern functions
1776 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1777 config word has been found
1778 * src/pic/device.h: added prototypes
1779 * src/pic/pcode.c: added "pic14_"-prefix where needed

2044 interrupts need an interrupt number now if they are made critical),
2045 and enabled nesting of critical functions though not for gbz80
2046 (genCritical, genEndCritical): added functions
2047 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2048 * src/z80/mappings.i: added "ei" to all mappings

2060 the left operand is shorter than the result (c* = lit-c* + int),
2062 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2065 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2067 * src/.version: increased version number to 2.5.5
2068 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2069 linking is done manually in pic16 port's _linkEdit,
2070 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2071 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2072 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2073 allocate asmop as AOP_ACC,
2074 (aopForRemat): added parameter 'bool result' in function declaration,
2075 (pic16_aopGet): return AOP_ACC when accessing WREG,
2076 (pic16_popGetTempReg): minor modification,

2087 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2088 call to allocReg, not by manually allocating a new one,
2089 (pic16_assignRegisters): now before going through the register
2090 allocating functions mark all registers as free. This eliminates some
2091 side effects resulting from peephole parser done earlier in the backbone
2093 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

2151 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2152 which dumps before the function entry point a data byte which represents
2153 the number of the local variables used by the specified function, added
2154 'xinst' for initial support for Extended Instruction Support,
2155 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2156 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2157 port->fun_prefix anymore (may change later),
2158 (genFunction, genEndFunction): do not store/restore local registers for
2159 _main (this should take care the --main-return command line option in
2161 (genOr): removed some legacy pic-port instructions,
2162 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2163 performing operations with SFR's causes data to be written more than
2164 once to each SFR. Perhaps SFRs should be handled in special cases...
2165 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2167 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2168 into account for stack starting position,

2170 --extended or -y for Extended Instruction Support,
2171 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2172 (deassignLRs): *** perhaps the most important change, old 'for' code
2173 (commented out for reference), didn't account for some registers which
2174 were left marked 'not free' after a pointer operation. The change
2175 reduces register usage a lot in some cases
2177 2006-03-04 Borut Razem <borut.razem AT siol.net>
2179 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

4450 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4451 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4452 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4453 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4454 always available in leading double underscore form. The C99 support is
4455 mostly missing, but it's a start.
4456 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4457 reserved identifier "__data".
4459 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

4535 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4537 * device/lib/printf_large.c: removed inline assembly for portability and
4538 readability. Use printf_fast if speed or size are more important.
4539 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4540 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4542 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4544 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4545 prevent compiler warning
4547 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4549 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4550 moved to level 0 and declared as static. Also they are explicit
4551 placed in access bank. This was necessery because some times they
4552 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4553 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4554 optimizations. Currently only compare to unsigned char is implemented,
4555 * src/pic16/gen.c: added fReturnIdx array,
4556 * (struct resolvedIfx) is moved to gen.h and made public,
4557 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4558 * (aopForSym): added an optimization to directly store in stack of
4559 the operand of a SEND iCode,
4560 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4561 but as registers instead (AOP_REG) using the fReturnIdx array,
4562 * (pic16_freeAsmop): remove the freed register from the
4563 _G.sregsAlloc field,
4564 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4565 a compare of 'WREG',
4566 * (pic16_popGetTempRegCond): changed function prototype, now
4567 function takes also a bitVector argument v which holds the current
4568 set of registers that are allocated for stack access by aopForSym,
4569 registers allocated in aopForSym for accessing stack symbols are not
4570 any more part of the functions usedRegs field,
4571 * (genCall): some times aopOp is called for a stack variable to be
4572 send, aopForSym might perform the push, if this is true make sure
4573 that genCall doesn't push the variable twice by testing _G.resDirect,
4574 * (genFunction): changed testing for unspecified interrupt number
4575 from 256 to INTNO_UNSPEC,
4576 * modified selection scheme of frame pointer generation. Previously
4577 if function did use local registers a frame pointer was generated,
4578 now a frame pointer is generated only if function has arguments
4579 (that need PLUSW2 register access), or has stack arguments, or the
4580 compiler is not instructed to omit the frame pointer,
4581 * (genEndFunction): before restoring local registers that were saved
4582 in the function preamble, also restore the registers that *might*
4583 have been allocated for stack access,
4584 * (genRet): removed some old comments,
4585 * (genCmp, the active (RN's) version): added a call to the
4586 pic16_genCmp_special function to perform the compare with a more
4587 robust and optimized way,
4588 * (genInline): a feature has been added in inline code generation,
4589 which allows a wildcard variable substitution when writing inline
4590 assembly. Code is incomplete and experimental therefore undocumented,
4591 * (genCast): changed order of aopOp for result and right to allow
4592 aopForSym to directly load the result if possible,
4593 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4594 perform an optimized compare on some selected special occasions,
4595 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4596 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4597 generate an IVT any more,
4598 * src/pic16/main.c (pic16_optionsTable): added command line option
4600 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4601 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4603 * src/pic16/NOTES: Raphael Neider added in list of active developers
4604 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4605 jumptable_end to prevent bug #,
4606 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4607 inCond and outCond fields,
4608 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4609 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4610 turn off register spilling,
4611 * (packRegsForOneUse): synced with other ports' versions although it
4612 is not used currently,
4613 * (pic16_packRegisters): added an optimization while reading
4614 structure bitfields, some registers may be saved (malloc code is
4615 decreased by 80 bytes)
4617 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4619 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4620 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4621 this can be optimized more?
4623 2005-03-10 Raphael Neider <rneider AT web.de>
4625 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4626 genNearPointerGet): (hopefully) fixed access to bitfields via
4627 pointers (p->bitN = x; and x = p->bitN; failed)

5261 Adding support for replacing ljmps with sjmps in jumptables
5262 generated for switch statements. For now you need to set the
5263 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5264 Now 4 algorithms for mcs51 jumptable generation are used:
5265 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5266 addresses loaded pc-relative for up to 112 cases and stack-pushing
5267 target addresses loaded with offset from dptr for up to 256 cases.

5294 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
5295 to call when a stack overflow occurs,
5296 * (malloc.h): added CVS Id tag,
5297 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5299 * added libc directory. The current version of LibC contains string
5300 functions, ctype functions and macros and some functions of the
5301 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5302 be extensively tested in the future. Standard disclaimer here.
5303 Library is not automatically build yet. But one can build it by
5304 invoking 'make' inside the libc directory.
5305 * added ADC library under libio. Preliminary version yet.
5307 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

5311 temporary registers, its a buggy feature and will be removed,
5312 * (pic16_popGet): set register instance field in AOP_CRY,
5313 * (pic16_outBitC): fixed for results in size greater than 1,
5314 * (genUminusFloat): fixed for pic16, ported code from mcs51,
5315 * (pic16_storeForReturn): optimized return of 0,
5316 * (genCmp): experimental code for new genCmp which uses PIC18's
5317 special compare&skip instructions. Initial tests fail some times
5318 with variables grater than 1 byte in size, so new code is disabled,
5319 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5321 * (genCast): began a fix to optimize the casting of a bit to another
5322 bit, now assigning a bitfield to another bitfield will fail, sorry,
5323 * src/pic16/main.c: disabled the use of lr-support feature,
5324 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

5327 bits with offset (case PO_GPR_BIT),
5328 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
5330 * (isBankInstruction): modified to return 0 for no banking instruction,
5331 and 1 for banking instruction,
5332 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5333 caused stop processing pCodes after a inline assembly block,
5334 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
5335 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
5336 registers when it shouldn't,
5337 * src/pic16/ralloc.c (allocReg): add preliminary support for
5338 supporting a limited set of temporary registers,
5340 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5342 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
5343 genDataPointerSet): ensure assignments always copy in MSB to LSB
5345 (loadRegFromAop): recognize CLRH optimization,
5346 (genFunction): optimize RECEIVE iCodes in reentrant functions
5348 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5350 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

8266 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
8267 'char' to 'int' can be omitted, if both operands are 'unsigned char';
8268 see feature request #877103
8269 * src/SDCCval.c: updated call of decorateType()
8270 (valBitwise): fixed bug #882876
8271 (valMinus): added promotion
8272 (valLogicAndOr): result is unsigned
8273 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
8274 * src/SDCCsymt.c (computeType),
8275 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
8276 must not cause an unsigned operation
8277 * src/pic/glue (pic14emitRegularMap),
8278 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
8280 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>

8295 * src/pic/pcoderegs.c,
8297 * src/pic/ralloc.h: applied patch from Slade Rich;
8298 added support for multiple code pages and multiple RAM banks on the
8299 PIC 14 port. The ASM files now no longer simply assume all the
8300 code / RAM are in the same page / bank. This means the linker can
8301 safely allocate code/RAM of separate ASM files to different pages/banks.
8302 * doc/sdccman.lyx: added Slade's tips
8303 * src/mcs51/peeph.def: fixed bug #880768

8312 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
8315 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
8316 strtof is not part of C89 and isn't included with Mac OS X.
8318 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8320 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

8345 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8347 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8348 loaded with the linker search paths (-L arguments) and the libraries
8349 to be linked with the current source (-l arguments). Changes
8350 currently will affect only the pic16 port.
8351 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8352 include path the port specific paths and port specific libraries,
8353 * gplink command now contains the $3 argument,
8354 * src/pic16/device.h,
8355 * src/pic16/device.c,: structure PIC_device is made public and
8356 renamed to PIC16_device, the same for variable Pics which is renamed

8369 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
8371 Documenting changes from previous commits.
8372 * configure.in (version 1.56),
8373 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8374 when generating output files to configure the pic16 library,
8375 but now I've commented it out, since gputils aren't installed in the
8376 SF compile farm, so library won't compile
8378 * device/lib/Makefile.in (version 1.56): initially I've added in
8379 target 'all' the prerequestive 'model-pic16' so it compiled the
8380 pic16 library, but now I've commented it out for the same reasons
8382 * added targets 'model-pic16' and 'objects-pic16' to compile the
8384 * added target 'port-specific-objects-pic16' to handle the
8385 generated libraries and copy them into the build/ directory
8386 * added target 'clean-intermediate-pic16' to clean intermediate
8387 files into pic16 directory
8388 * in target 'installdirs' added line to create directory pic16 in
8389 the installation path
8391 * device/include/Makefile.in (version 1.11): in target 'install'
8392 added lines to copy all header files to installation path,
8393 * in target 'installdirs' added line create directory for pic16
8394 headers in the installation path

8409 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8410 option so that it actually works. Made it specific to the z80, since
8411 the gbz80 doesn't have these kinds of I/O ports.
8413 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8415 * device/include/z180.h,

8437 Mainly changes to support compilation of the device libraries
8438 * src/pic16/device.c: stack is allocated via symbol and not
8439 via literal number. The symbol is placed in the corresponding
8440 position of the data ram
8441 * (pic16_dump_section): relocatable and absolute uninitialized
8442 data are now emitted in sorted order to reduce section naming,
8443 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8444 weren't marked as being in the access bank,
8446 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8448 Added portion of GNU PIC Library under the directory
8449 device/include/pic16 and device/lib/pic16. These files
8450 contain the declarations of SFRs for the PIC18Fxx2 devices.
8451 The directory is initialized via configure from toplevel.
8453 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
8455 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

8481 all over. Telling LaTeX to be less strict with word spacing
8482 to better keep the right margin. Changed some notes about
8483 maintainance of the ports in section 3.2.1 - is it OK like this?
8485 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8523 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8525 * src/pic16/peeph.def: all peepholes with movff are commented out,
8526 because there is a problem in the pcode peep optimizer,
8527 * src/pic16/ralloc.c: the register allocator can now reuse local

8676 * src/ds390/gen.c (genRightShift): fixed bug #870788
8677 * src/SDCCast.c (decorateType): fixed bug #870781
8679 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8681 PIC16 port related changes:
8682 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8683 added variable stackPos,
8685 * gen.c: genCall, assignResultValue: added support for
8686 pushing/retrieving function parameters to/from stack,
8687 genFunction,genEndFunction: setup stack frame for the
8689 genAddrOf: will be changed according to bug 863624
8691 * added files genutils.c and genutils.h which contain gen*
8692 debugged and optimised functions extracted from gen.c
8694 * glue.c: added variable 'externs' which holds extern symbols,
8695 pic16emitRegularMap: is modified to properly handle relocatable
8696 symbols under the new scheme,
8697 pic16createInterruptVect: is modified
8698 pic16printPublics: is modified to emit 'global' assembler directives,
8699 added pic16_printExterns to print extern symbols,
8700 pic16glue: initializes stack/frame pointer in the beginning of
8701 the assembly output. Temporary hack, will be corrected later,
8702 because gplink yet does not support stack and SDCC does not
8703 yet support a type of crt0.o object to create the final binary.
8705 * Removed many lines that contain 8051 legacy code.
8706 * The code is finally placed under a 'code' directive.
8707 * Added port specific options.
8709 * _process_pragma: simplified since now we do not need *special*
8710 include file to define SFR registers. But a separate header
8711 will be needed. This will be developed later.
8712 * _pic16_parseOptions: added, parses port specific options:
8713 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8714 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8715 --preplace-udata-with=
8717 * _pic16_setDefaultOptions: modified to initialize section names,
8718 but hack is temporarly out of order since it needs improvement.
8719 * _pic16_genAssemblerPreamble: configuration words are emitted by
8720 their address instead of their name. This part is incomplete and
8721 supports only the 18Fxx2 devices. Other devices will emit an error
8722 during assembly since they do not contain the same set of config
8724 * _pic16_genIVT: is modified,
8726 * pcode.c: added definitions for some hardware registers that are needed
8728 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8729 All PCI entries are updated. Now LFSR is supported.
8730 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8731 * added pic16_newpCodeOpLit2 to support instructions with
8732 two literal arguments
8733 * pic16_pCode2str: corrected code that emits assembler instructions
8734 with two literal operands and those that have an access bit modifier
8735 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8736 this fixes a bug which caused some labels to be lost, when an
8737 assembler directive was added, i.e. banksel,
8738 * pic16_FixRegisterBanking: improved logic that causes the insertion
8740 * InlineFunction: functions that are called once, are not any more
8741 inlined. This can be a port option in the future,
8743 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8745 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8746 hold the corresponding uninitialized symbols,
8747 * pic16_allocProcessorRegister: registers have explicit marked the
8749 * pic16_allocInternalRegister: registers are explicit marked as
8751 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8752 processing list, so bit registers were lost,
8755 * ralloc.h: added field 'accessBank' and original symbol operand
8756 in register definition,
8757 * removed the field isMapped from register definition,
8759 ** Several functions have been removed from various sources:

8771 * support/scripts/inc2h.pl: changed definition of BIT_AT
8772 to emit 'sbit at' instead of 'bit at'. This was a request.
8774 PIC16 port related preliminary changes:
8775 * gen.c: prefixed function popRegFromString with
8776 pic16_ and all references to it corrected
8777 * pcode.c: all pic16_pc_* hardware registers prefixed
8778 with underscore (_),
8779 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8780 * ralloc.c: newReg(): when register is REG_SFR then
8781 set address to rIdx,
8782 pic16_allocProcessorRegister(): marks register wasUsed=0
8783 pic16_writeUsedRegs(): added a call to assign processor
8784 registers via pic16_assignFixedRegisters
8786 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8788 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8789 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8790 variables in unused register banks. Also the SSEG is placed
8791 wherever there is enough space for it, and IDATA can be anywhere
8792 in internal RAM. For now compile using -Wl-Y[stack_size].
8793 The mem file is different for this option as well, since it
8794 makes no sense of talking about DSEG lenght.
8796 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8798 * src/SDCClrange.c: fixed bug 869095 that caused segfault

9045 it breaks with bitfields, extern declarations, and gcse analysis.
9046 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
9047 could be assigned through a pointer, so don't complain.

9791 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
9792 iCode properly now. Use getSize instead of nRegs since a & b
9793 aren't part of the nRegs tally.
9795 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
9797 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

9804 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9805 fetching of the pointer
9806 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9807 copied from genNearPointerSet()
9808 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9809 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9810 If they pop r0/r1 they must be called in the opposite order than aopOp().
9811 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9812 (resp. --stack-auto), prepared for --xstack

9823 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9825 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9826 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9827 type for bits was changed. It resulted in bit variables becoming
9828 global, which is not permitted in PIC 14 assembly output.
9830 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9832 * doc/sdccman.lyx: various additions and updates. Rearranged sections
9834 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9836 Z80 and MCS51 linkers complaint if a public symbol is defined

9845 A few small changes that speed up the peephole optimizer.
9849 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9851 Try to make the peephole optimizer smarter by maintaining
9852 an association between the assembly source code and the
9853 iCodes that originated them. Put this information to use
9854 with a new peephole rule condition "notVolatile" so that
9855 the rules can be aggressive yet still safe.
9860 * src/mcs51/peeph.def
9862 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9866 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9867 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9868 if the left or right operand symbols have the accuse flag set.
9870 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9872 Changed the type of the result of the ! (NOT) operator to char;
9873 previously it returned the same type as the source. This allows
9874 us to eliminate all the genFloatNot functions (all of its target
9875 implementations were very buggy) since !float can use the same
9878 * src/SDCCicode.c (ast2iCode): ! returns char

9885 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
9887 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9888 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9889 during interrupts. Ensure WSAVE is located at a shared bank address.
9890 2. Fixed page selection in some places
9891 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9892 the registers name strings.
9893 4. Fixed "signed / unsigned compare" compiler warnings.
9894 5. The PIC port manages its own allocation of the general purpose
9895 registers, but makes no attempt to reuse them. As a result when
9896 compiling it soon runs out of general purpose registers. Some
9897 additional code was added to the files pcode.c and device.c to walk
9898 through the function call tree and rename the registers so that they
9908 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9909 genPlus() & genMinus() when the result is the same as left or right

9915 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9917 Made bitfield a distinct type from bit so that bitfields
9918 convert as per ANSI C and bits retain their traditional
9919 boolean style behaviour. Implemented bitfield support in
9927 * src/ds390/gen.c: bit v bitfield split
9928 * src/z80/gen.c: New support for bitfields
9929 * support/regression/tests/bitfields.c: reenabled z80,
9932 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9934 Rules 246.x, 247.x relate to bitfields, the others speed up
9935 access to xdata mapped I/O devices.
9937 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9939 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9941 Cleaned up genPackBits and genUnpackBits and added two helper
9942 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9943 for literal assignments in genPackBits (thanks to Frieder for
9949 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9951 Fixed bug #748310 (pointer to function type mishandled when the
9952 function name is omitted). Also fixed a SIGSEGV when a function
9953 attribute (reentrant, etc) is used on a non-function or on a
9954 function but misplaced before the parameter list.
9956 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9958 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9959 * support/Util/SDCCerr.h,
9960 * support/Util/SDCCerr.c: Added func attr misuse error msg

9981 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9983 Made the constant following the "interrupt" keyword optional. If
9984 omitted, the function will not automatically be given an entry
9985 in the interrupt vector table (similar to #pragma NOIV, but
9986 less syntacticly kludgy). The interrupt number is also now
9987 range checked. Also fixed a bug in the high order bit example

10003 * src/SDCCsymt.c (computeType): literals are handled the same way as any
10005 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
10006 be re-activated by defining REDUCE_LITERALS)
10007 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10008 unsigned, but are signed by default
10009 * src/SDCCval.c (constVal): rearranged
10010 * src/SDCCval.c (valMod): preliminary fix

10463 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
10464 the regression tests I'm not brave enough to enable 245.b, 245.c
10465 * doc/sdccman.lyx: added latex preamble for hyperref package.
10466 Using pdflatex this will give you a hyperlinked pdf file with

10516 * src/SDCCmain.c: linkOptions is changed to set *,
10517 added if/endif conditional macros to remove options help
10518 messages from optionsTable when a port is not configured, added
10519 support for the PIc16 port in the ports table, when executing
10520 the compiler with no port specified on command line, a default
10521 port is selected with the new macro DEFAULT_PORT which is
10522 defined in port.h, in setDefaultOptions() linkOptions is removed
10523 from initialization assignment, since now it is a set,
10524 parseCmdLine uses setParseWithComma for linkOptions, in
10525 linkEdit() linkOptions are accessed with new function indexSet()
10526 which returns the i'th item of a set variable. See SDCCset.c, in
10527 linkEdit() when calling buildCmdLine(), added linkOptions as
10528 last argument. Now users can pass arguments to gplink via the
10529 -Wl option, main() uses pic16glue() to glue up pic16 programs
10530 * src/SDCCpeeph.c: various changes to support pic16
10531 * src/SDCCset.c: added function void *indexSet(set *, int) to

10541 * src/pic16/glue.c: commented out some error producing lines
10542 * src/pic16/main.c: __config directives are commented out to stop
10543 gpasm complaining and test the linkage with gplink, _linkCmd and
10544 _asmCmd changed to be more gplink and gpasm friendly
10545 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10546 produced an error when parsed, peep rule 12 is added to utilize
10547 movff, but it is commented out since the pCode does not support
10548 yet a command with 2 address arguments
10550 2003-05-18 <johan AT balder>
10552 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

10579 2003-05-11 Borut Razem <borut.razem AT siol.net>
10581 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
10582 the path of bin directory, so that PATH is the only env. variable, which has to be set

11593 2003-01-04 <johan AT balder>
11595 * src/SDCCval.c (getNelements): fixed the initialized array of structures
11597 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11598 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
11600 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11601 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
11602 * support/regression/tests/bug-524697.c: fit mem usage into 8032
11604 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11605 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
11607 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11608 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11610 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11611 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11613 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11615 * in /sdcc/as/mcs51/ changed these files in order to create an
11616 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11617 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11618 following files to include the previous two files: aslink.dsp,
11619 Makefile.aslink, Makefile.bcc, and Makefile.in.
11621 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11622 .adb instead of .cdb
11624 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11626 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11627 value from option --iram-size.
11629 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11631 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11634 2002-09-18 <wiml AT hhhh.org>
11636 * SDCClrange.h: exposed setFromRange() and setToRange()
11637 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11638 packRegsForAccUse() (bug 542397)
11639 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11640 multiple times and emitting the fetch operations more than once
11641 added aopGetUsesAcc() function to allow binary operators to
11642 fetch their operands in the correct order; made genMinus() emit
11643 compact code for X = LITERAL - Y
11645 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11646 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11647 sprintf() in line 1267.
11649 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11650 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11653 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11654 Changes to aslink (All the changes are marked with 'JCF'):
11656 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11659 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11660 area BSEG. Also moves, if possible, the DATA area down into the internal
11661 ram so more space is available.
11663 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11666 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11667 not bytes. Function summary() which creates a memory usage summary
11668 file with extension .mem. Reports of overlaping stack and small stack
11669 size. If the space for the stack is less than 16 bytes aslink trows a
11672 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11673 the 8051. Option 'y' for memory summary output file.
11675 Changes to sdcc (All the changes are marked with 'JCF'):
11677 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11679 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11680 overlaying area for it (uses RegBankUsed[4]).
11682 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11683 bank zero as used by default. By default aslink locates the stack
11684 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11685 the creation of the .mem file. Delegates the allocation of data area
11686 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11687 the begining of the stack area to aslink.
11689 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11690 glue() in SDCCglue.c creates an area for it.
11692 2002-09-03 Borut Razem <borut.razem AT siol.net>
11693 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11694 sdcc/src/pic/glue.c:
11695 introduced atexit() handler for teporay files removal in case of
11696 errors, assertions, ...
11698 2002-08-29 Borut Razem <borut.razem AT siol.net>
11699 * sdcc/support/cpp2/auto-host_vc_in.h:
11700 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11701 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11702 Maybe there is a similar problem with BORLANDC? It should be checked!
11704 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11705 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11706 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11707 was not executed, and the compiler (cl) launched a warning:
11708 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11710 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11711 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11713 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11714 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11716 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11717 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11718 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11719 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11720 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11721 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11722 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11723 - added Release configuration in VS projects
11724 - review of compiler an linker options
11725 - VC .exe files are generated in bin_vc directory, not to interfere
11726 with binaries generated from other projects (cygwin, mingw, bcc ...)
11728 * sdcc/src/yacc.dsp: added
11730 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11731 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11732 and insert the version number definitions from .version
11734 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11736 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11737 added - genarate auto-host.h using auto-host_vc_in.h as template
11740 removed from CVS, generated automatically
11742 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11743 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11745 2002-08-11 Borut Razem <borut.razem AT siol.net>
11746 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11748 2002-08-10 Borut Razem <borut.razem AT siol.net>
11749 * src/SDCCmain.c (main):
11750 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11751 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11752 The consequence was that some temporary files were not removed.
11755 unification of code in functions tempfilename() and tempfile():
11756 function tempnam() is defined in Visual Studio 6.0 and .NET
11758 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11760 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11761 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11762 - removed compiler command line option /WX: Treats all warnings as errors
11763 - update a list of source files, included into the project
11765 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11766 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11767 changed project type to Generic Project so that can be correcly converted to VS.NET project
11769 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11771 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11773 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11775 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11776 added return 0 statements after assert() to make compiler happy
11778 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11779 added newline in the def file to keep MSC compiler satisfied
11781 * sdcc/src/z80/gen.c:
11782 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11783 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11784 - solved MSC error in function aopDump()
11786 * sdcc_vc.h: define PREFIX as "\\sdcc"
11788 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11789 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11792 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11793 - Rewrote the register banking algorithm.
11794 - Added pCode live-range analysis to registers (for now, only non-used and
11795 singly-used registers optimized away)
11797 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11799 * 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.

11824 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11826 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11828 2002-03-28 Johan Knol <johan AT balder>
11830 * src/SDCCval.c: fixed bug #532436
11832 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11834 Added "char *Processor" field to the port structure.
11837 Added -p option. Allows port dependent processor to be specified.
11840 Initialized the new field char *Processor field to NULL in all ports
11843 Compiler generated registers for interrupt context saving
11844 were not getting allocated.
11846 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11849 Fixed left shift. Will promote the left side of a left shift
11850 if a) left shifting more than size of operand or b) when assigned
11851 to something size > size of left side
11853 2002-03-14 Scott Dattalo <scott AT dattalo.com>

11857 analysis is restructured. ...
11859 * src/pic/device.h:
11862 * src/pic/device.c:
11863 Added. device.c is a PIC port hack to accomodate variations
11866 2002-03-13 Michael Hope <michaelh AT vroom>
11868 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11870 2002-03-04 johanknol <johanknol AT manik>
11872 * /src/SDCCval.c: fixed
11874 const unsigned char arr[][2] = { { 0, 1 } };

11961 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11963 * sdcc/src/SDCCloop.c:
11964 Previous fix was not good. basic blocks that have "break" or "return" are
11965 not really partof a loop , but live ranges used in these blocks should
11966 be live thru the entire loop, so set partOfLoop but don't add them to
11969 2002-02-21 <johan AT FRIJA>
11971 * src/SDCCcse.c: fixed bug #514308
11973 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
11976 Fixed BUG #519583. If a conditional block ended in a return/break
11977 statement inside a loop, it was not being considered part of the loop.
11979 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
11981 2002-02-10 Karl Bongers <karl AT turbobit.com>

11995 Took out debug printfs in ucsim "next" command.
11997 * sim/ucsim/xa.src:
11998 Karl and Johan start ucsim XA support. Most dissassembly working,
11999 about 75% emulation done(plenty of work remaining).
12001 * sim/ucsim/z80.src:
12002 Add Z80 support to ucsim, add test-ucz80 regression test,
12003 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
12004 Notice z80 compiler fails on examples/test3.c/crc code.
12006 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>

12021 1) handle multiple send & receives from register bank1
12022 2) ralloc can now allocate DPTR1 to some liveRanges
12024 * src/SDCCsymt.c, src/SDCCsymt.h:
12025 changes to handle multiple sends & receives
12027 * src/SDCCptropt.h:
12028 added some pointer arithmetic optimization
12030 * src/SDCCptropt.c:

12037 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
12038 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
12039 set preprocessor defines (depending on options)
12041 * src/SDCCicode.c, src/SDCCicode.h:
12042 changes made to handle multiple sends & receives
12045 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
