1324 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1326 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1327 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1329 One basic decision: e.g. src/clean.mk includes further files. In order
1330 to make this work there are two solutions:
1331 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1332 run configure on them. This way they can use
1333 'include $(srcdir)/port-clean.mk'
1334 - always include clean.mk by the Makefile at the same level. To avoid
1335 that `make clean` tries to include and build Makefile.dep the
1336 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1337 implemented, because now even `make uninstall` doesn't create
1338 Makefile.in. clean.mk could be eliminated by pasting it in
1341 * debugger/mcs51/Makefile.in: build own objects from library sources
1342 (SLIB, SDCC) in current directory
1344 * configure, configure.in: renamed --disable-device-lib-build in
1345 --disable-device-lib; added --enable-doc, the required tools are
1346 searched by configure; added result message; the toolchain for the
1347 belonging ports are now only built, if the port is enabled.
1349 * support/regression/*: all output is written in directory gen, because
1350 the fwk and ports directories don't livet in the build tree using vpath
1352 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1353 --disable-device-lib, added --enable-doc, added section VPATH
1355 * sim/ucsim/configure.in,
1356 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and

1607 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
1609 * src/mcs51/gen.c (genCall): fixed bug 1457608
1611 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

1630 implemented patch 1120823 Thanks to Willy De la Court (normal
1631 interrupts need an interrupt number now if they are made critical),
1632 and enabled nesting of critical functions though not for gbz80
1633 (genCritical, genEndCritical): added functions
1634 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1635 * src/z80/mappings.i: added "ei" to all mappings

1644 2006-03-16 Raphael Neider <rneider AT web.de>
1646 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1647 the left operand is shorter than the result (c* = lit-c* + int),
1649 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1652 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1654 * src/.version: increased version number to 2.5.5
1655 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1656 linking is done manually in pic16 port's _linkEdit,
1657 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1658 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1659 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1660 allocate asmop as AOP_ACC,
1661 (aopForRemat): added parameter 'bool result' in function declaration,
1662 (pic16_aopGet): return AOP_ACC when accessing WREG,
1663 (pic16_popGetTempReg): minor modification,

1674 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1675 call to allocReg, not by manually allocating a new one,
1676 (pic16_assignRegisters): now before going through the register
1677 allocating functions mark all registers as free. This eliminates some
1678 side effects resulting from peephole parser done earlier in the backbone
1680 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1730 2006-03-06 Borut Razem <borut.razem AT siol.net>
1732 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1733 made the linker quiet
1735 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1737 * src/pic16/gen.c (genPcall): fixed bug #1443644
1738 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1739 which dumps before the function entry point a data byte which represents
1740 the number of the local variables used by the specified function, added
1741 'xinst' for initial support for Extended Instruction Support,
1742 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1743 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1744 port->fun_prefix anymore (may change later),
1745 (genFunction, genEndFunction): do not store/restore local registers for
1746 _main (this should take care the --main-return command line option in
1748 (genOr): removed some legacy pic-port instructions,
1749 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1750 performing operations with SFR's causes data to be written more than
1751 once to each SFR. Perhaps SFRs should be handled in special cases...
1752 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1754 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1755 into account for stack starting position,
1756 (struct OPTIONS pic16_optionsTable): added command line argument
1757 --extended or -y for Extended Instruction Support,
1758 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1759 (deassignLRs): *** perhaps the most important change, old 'for' code
1760 (commented out for reference), didn't account for some registers which
1761 were left marked 'not free' after a pointer operation. The change
1762 reduces register usage a lot in some cases
1764 2006-03-04 Borut Razem <borut.razem AT siol.net>
1766 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

4037 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4038 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4039 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4040 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4041 always available in leading double underscore form. The C99 support is
4042 mostly missing, but it's a start.
4043 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4044 reserved identifier "__data".

4122 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4124 * device/lib/printf_large.c: removed inline assembly for portability and
4125 readability. Use printf_fast if speed or size are more important.
4126 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4127 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4129 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4131 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4132 prevent compiler warning
4134 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4136 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4137 moved to level 0 and declared as static. Also they are explicit
4138 placed in access bank. This was necessery because some times they
4139 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4140 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4141 optimizations. Currently only compare to unsigned char is implemented,
4142 * src/pic16/gen.c: added fReturnIdx array,
4143 * (struct resolvedIfx) is moved to gen.h and made public,
4144 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4145 * (aopForSym): added an optimization to directly store in stack of
4146 the operand of a SEND iCode,
4147 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4148 but as registers instead (AOP_REG) using the fReturnIdx array,
4149 * (pic16_freeAsmop): remove the freed register from the
4150 _G.sregsAlloc field,
4151 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4152 a compare of 'WREG',
4153 * (pic16_popGetTempRegCond): changed function prototype, now
4154 function takes also a bitVector argument v which holds the current
4155 set of registers that are allocated for stack access by aopForSym,
4156 registers allocated in aopForSym for accessing stack symbols are not
4157 any more part of the functions usedRegs field,
4158 * (genCall): some times aopOp is called for a stack variable to be
4159 send, aopForSym might perform the push, if this is true make sure
4160 that genCall doesn't push the variable twice by testing _G.resDirect,
4161 * (genFunction): changed testing for unspecified interrupt number
4162 from 256 to INTNO_UNSPEC,
4163 * modified selection scheme of frame pointer generation. Previously
4164 if function did use local registers a frame pointer was generated,
4165 now a frame pointer is generated only if function has arguments
4166 (that need PLUSW2 register access), or has stack arguments, or the
4167 compiler is not instructed to omit the frame pointer,
4168 * (genEndFunction): before restoring local registers that were saved
4169 in the function preamble, also restore the registers that *might*
4170 have been allocated for stack access,
4171 * (genRet): removed some old comments,
4172 * (genCmp, the active (RN's) version): added a call to the
4173 pic16_genCmp_special function to perform the compare with a more
4174 robust and optimized way,
4175 * (genInline): a feature has been added in inline code generation,
4176 which allows a wildcard variable substitution when writing inline
4177 assembly. Code is incomplete and experimental therefore undocumented,
4178 * (genCast): changed order of aopOp for result and right to allow
4179 aopForSym to directly load the result if possible,
4180 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4181 perform an optimized compare on some selected special occasions,
4182 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4183 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4184 generate an IVT any more,
4185 * src/pic16/main.c (pic16_optionsTable): added command line option
4187 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4188 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4190 * src/pic16/NOTES: Raphael Neider added in list of active developers
4191 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4192 jumptable_end to prevent bug #,
4193 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4194 inCond and outCond fields,
4195 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4196 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4197 turn off register spilling,
4198 * (packRegsForOneUse): synced with other ports' versions although it
4199 is not used currently,
4200 * (pic16_packRegisters): added an optimization while reading
4201 structure bitfields, some registers may be saved (malloc code is
4202 decreased by 80 bytes)
4204 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4206 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4207 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4208 this can be optimized more?
4210 2005-03-10 Raphael Neider <rneider AT web.de>
4212 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4213 genNearPointerGet): (hopefully) fixed access to bitfields via
4214 pointers (p->bitN = x; and x = p->bitN; failed)
4216 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4848 Adding support for replacing ljmps with sjmps in jumptables
4849 generated for switch statements. For now you need to set the
4850 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4851 Now 4 algorithms for mcs51 jumptable generation are used:
4852 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4853 addresses loaded pc-relative for up to 112 cases and stack-pushing
4854 target addresses loaded with offset from dptr for up to 256 cases.

4884 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4886 * added libc directory. The current version of LibC contains string
4887 functions, ctype functions and macros and some functions of the
4888 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4889 be extensively tested in the future. Standard disclaimer here.
4890 Library is not automatically build yet. But one can build it by
4891 invoking 'make' inside the libc directory.
4892 * added ADC library under libio. Preliminary version yet.

4902 * (pic16_storeForReturn): optimized return of 0,
4903 * (genCmp): experimental code for new genCmp which uses PIC18's
4904 special compare&skip instructions. Initial tests fail some times
4905 with variables grater than 1 byte in size, so new code is disabled,
4906 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4908 * (genCast): began a fix to optimize the casting of a bit to another
4909 bit, now assigning a bitfield to another bitfield will fail, sorry,
4910 * src/pic16/main.c: disabled the use of lr-support feature,
4911 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4918 and 1 for banking instruction,
4919 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4920 caused stop processing pCodes after a inline assembly block,
4921 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

4923 registers when it shouldn't,
4924 * src/pic16/ralloc.c (allocReg): add preliminary support for
4925 supporting a limited set of temporary registers,
4927 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7838 * support/regression/generate-cases.py (main): Changed from inline
7841 * doc/Makefile (install): Changed to depth first to get rid of
7842 missing directory install warning.
7844 * as/Makefile (install-doc): Made work on Mac.
7846 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
7848 * src/SDCCast.c: added an additional type flow in decorateType() of
7849 opposite direction, see feature request #860006; it's enabled at runtime
7850 by setting the environment variable SDCC_NEWTYPEFLOW
7851 * src/SDCCast.h: changed prototype of decorateType()
7852 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
7853 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
7854 'char' to 'int' can be omitted, if both operands are 'unsigned char';
7855 see feature request #877103
7856 * src/SDCCval.c: updated call of decorateType()
7857 (valBitwise): fixed bug #882876
7858 (valMinus): added promotion
7859 (valLogicAndOr): result is unsigned
7860 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
7861 * src/SDCCsymt.c (computeType),
7862 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
7863 must not cause an unsigned operation
7864 * src/pic/glue (pic14emitRegularMap),
7865 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
7867 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>

7884 * src/pic/ralloc.h: applied patch from Slade Rich;
7885 added support for multiple code pages and multiple RAM banks on the
7886 PIC 14 port. The ASM files now no longer simply assume all the
7887 code / RAM are in the same page / bank. This means the linker can
7888 safely allocate code/RAM of separate ASM files to different pages/banks.
7889 * doc/sdccman.lyx: added Slade's tips
7890 * src/mcs51/peeph.def: fixed bug #880768

7899 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
7902 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
7903 strtof is not part of C89 and isn't included with Mac OS X.
7905 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7907 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

7932 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7934 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7935 loaded with the linker search paths (-L arguments) and the libraries
7936 to be linked with the current source (-l arguments). Changes
7937 currently will affect only the pic16 port.
7938 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7939 include path the port specific paths and port specific libraries,
7940 * gplink command now contains the $3 argument,
7941 * src/pic16/device.h,
7942 * src/pic16/device.c,: structure PIC_device is made public and
7943 renamed to PIC16_device, the same for variable Pics which is renamed

7958 Documenting changes from previous commits.
7959 * configure.in (version 1.56),
7960 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7961 when generating output files to configure the pic16 library,
7962 but now I've commented it out, since gputils aren't installed in the
7963 SF compile farm, so library won't compile
7965 * device/lib/Makefile.in (version 1.56): initially I've added in
7966 target 'all' the prerequestive 'model-pic16' so it compiled the
7967 pic16 library, but now I've commented it out for the same reasons
7969 * added targets 'model-pic16' and 'objects-pic16' to compile the
7971 * added target 'port-specific-objects-pic16' to handle the
7972 generated libraries and copy them into the build/ directory
7973 * added target 'clean-intermediate-pic16' to clean intermediate
7974 files into pic16 directory
7975 * in target 'installdirs' added line to create directory pic16 in
7976 the installation path
7978 * device/include/Makefile.in (version 1.11): in target 'install'
7979 added lines to copy all header files to installation path,
7980 * in target 'installdirs' added line create directory for pic16
7981 headers in the installation path

7996 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7997 option so that it actually works. Made it specific to the z80, since
7998 the gbz80 doesn't have these kinds of I/O ports.
8000 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8002 * device/include/z180.h,

8024 Mainly changes to support compilation of the device libraries
8025 * src/pic16/device.c: stack is allocated via symbol and not
8026 via literal number. The symbol is placed in the corresponding
8027 position of the data ram
8028 * (pic16_dump_section): relocatable and absolute uninitialized
8029 data are now emitted in sorted order to reduce section naming,
8030 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8031 weren't marked as being in the access bank,
8033 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8035 Added portion of GNU PIC Library under the directory
8036 device/include/pic16 and device/lib/pic16. These files
8037 contain the declarations of SFRs for the PIC18Fxx2 devices.
8038 The directory is initialized via configure from toplevel.

8068 all over. Telling LaTeX to be less strict with word spacing
8069 to better keep the right margin. Changed some notes about
8070 maintainance of the ports in section 3.2.1 - is it OK like this?
8072 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8112 * src/pic16/peeph.def: all peepholes with movff are commented out,
8113 because there is a problem in the pcode peep optimizer,
8114 * src/pic16/ralloc.c: the register allocator can now reuse local

8253 Bug reported from Jesus Calvino-Fraga
8255 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8257 * sdcc.spec: updated
8258 * device/include/Makefile.in: don't install CVS directories

8263 * src/ds390/gen.c (genRightShift): fixed bug #870788
8264 * src/SDCCast.c (decorateType): fixed bug #870781
8266 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8268 PIC16 port related changes:
8269 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8270 added variable stackPos,
8272 * gen.c: genCall, assignResultValue: added support for
8273 pushing/retrieving function parameters to/from stack,
8274 genFunction,genEndFunction: setup stack frame for the
8276 genAddrOf: will be changed according to bug 863624
8278 * added files genutils.c and genutils.h which contain gen*
8279 debugged and optimised functions extracted from gen.c
8281 * glue.c: added variable 'externs' which holds extern symbols,
8282 pic16emitRegularMap: is modified to properly handle relocatable
8283 symbols under the new scheme,
8284 pic16createInterruptVect: is modified
8285 pic16printPublics: is modified to emit 'global' assembler directives,
8286 added pic16_printExterns to print extern symbols,
8287 pic16glue: initializes stack/frame pointer in the beginning of
8288 the assembly output. Temporary hack, will be corrected later,
8289 because gplink yet does not support stack and SDCC does not
8290 yet support a type of crt0.o object to create the final binary.
8292 * Removed many lines that contain 8051 legacy code.
8293 * The code is finally placed under a 'code' directive.
8294 * Added port specific options.
8296 * _process_pragma: simplified since now we do not need *special*
8297 include file to define SFR registers. But a separate header
8298 will be needed. This will be developed later.
8299 * _pic16_parseOptions: added, parses port specific options:
8300 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8301 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8302 --preplace-udata-with=
8304 * _pic16_setDefaultOptions: modified to initialize section names,
8305 but hack is temporarly out of order since it needs improvement.
8306 * _pic16_genAssemblerPreamble: configuration words are emitted by
8307 their address instead of their name. This part is incomplete and
8308 supports only the 18Fxx2 devices. Other devices will emit an error
8309 during assembly since they do not contain the same set of config
8311 * _pic16_genIVT: is modified,
8313 * pcode.c: added definitions for some hardware registers that are needed
8315 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8316 All PCI entries are updated. Now LFSR is supported.
8317 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8318 * added pic16_newpCodeOpLit2 to support instructions with
8319 two literal arguments
8320 * pic16_pCode2str: corrected code that emits assembler instructions
8321 with two literal operands and those that have an access bit modifier
8322 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8323 this fixes a bug which caused some labels to be lost, when an
8324 assembler directive was added, i.e. banksel,
8325 * pic16_FixRegisterBanking: improved logic that causes the insertion
8327 * InlineFunction: functions that are called once, are not any more
8328 inlined. This can be a port option in the future,
8330 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8332 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8333 hold the corresponding uninitialized symbols,
8334 * pic16_allocProcessorRegister: registers have explicit marked the
8336 * pic16_allocInternalRegister: registers are explicit marked as
8338 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8339 processing list, so bit registers were lost,
8342 * ralloc.h: added field 'accessBank' and original symbol operand
8343 in register definition,
8344 * removed the field isMapped from register definition,
8346 ** Several functions have been removed from various sources:
8347 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8348 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8349 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8350 pic16_assignRelocatableRegisters
8352 ** others have been introduced:
8353 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8354 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8356 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8358 * support/scripts/inc2h.pl: changed definition of BIT_AT
8359 to emit 'sbit at' instead of 'bit at'. This was a request.
8361 PIC16 port related preliminary changes:
8362 * gen.c: prefixed function popRegFromString with
8363 pic16_ and all references to it corrected
8364 * pcode.c: all pic16_pc_* hardware registers prefixed
8365 with underscore (_),
8366 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8367 * ralloc.c: newReg(): when register is REG_SFR then
8368 set address to rIdx,
8369 pic16_allocProcessorRegister(): marks register wasUsed=0
8370 pic16_writeUsedRegs(): added a call to assign processor
8371 registers via pic16_assignFixedRegisters
8373 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8375 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8376 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8377 variables in unused register banks. Also the SSEG is placed
8378 wherever there is enough space for it, and IDATA can be anywhere
8379 in internal RAM. For now compile using -Wl-Y[stack_size].
8380 The mem file is different for this option as well, since it
8381 makes no sense of talking about DSEG lenght.
8383 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8385 * src/SDCClrange.c: fixed bug 869095 that caused segfault

8630 * src/SDCCast.c (decorateType): disabled a transformation I added in
8631 revision 1.188 (access to fields of a structure at an absolute address);
8632 it breaks with bitfields, extern declarations, and gcse analysis.
8633 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8634 could be assigned through a pointer, so don't complain.

9391 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9392 fetching of the pointer
9393 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9394 copied from genNearPointerSet()
9395 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9396 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

9410 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9412 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9413 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9414 type for bits was changed. It resulted in bit variables becoming
9415 global, which is not permitted in PIC 14 assembly output.
9417 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9419 * doc/sdccman.lyx: various additions and updates. Rearranged sections
9421 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9423 Z80 and MCS51 linkers complaint if a public symbol is defined
9424 in more than one library module:

9430 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9432 A few small changes that speed up the peephole optimizer.
9436 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9438 Try to make the peephole optimizer smarter by maintaining
9439 an association between the assembly source code and the
9440 iCodes that originated them. Put this information to use
9441 with a new peephole rule condition "notVolatile" so that
9442 the rules can be aggressive yet still safe.
9447 * src/mcs51/peeph.def
9449 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9453 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9454 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9455 if the left or right operand symbols have the accuse flag set.
9457 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9459 Changed the type of the result of the ! (NOT) operator to char;
9460 previously it returned the same type as the source. This allows
9461 us to eliminate all the genFloatNot functions (all of its target
9462 implementations were very buggy) since !float can use the same
9465 * src/SDCCicode.c (ast2iCode): ! returns char
9466 * src/mcs51/gen.c (genNot, genNotFloat),
9467 * src/ds390/gen.c (genNot, genNotFloat),
9468 * src/z80/gen.c (genNot, genNotFloat),
9469 * src/pic/gen.c (genNot, genNotFloat),
9470 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
9472 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
9474 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9475 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9476 during interrupts. Ensure WSAVE is located at a shared bank address.
9477 2. Fixed page selection in some places
9478 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9479 the registers name strings.
9480 4. Fixed "signed / unsigned compare" compiler warnings.
9481 5. The PIC port manages its own allocation of the general purpose
9482 registers, but makes no attempt to reuse them. As a result when
9483 compiling it soon runs out of general purpose registers. Some
9484 additional code was added to the files pcode.c and device.c to walk
9485 through the function call tree and rename the registers so that they
9495 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9496 genPlus() & genMinus() when the result is the same as left or right

9502 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9504 Made bitfield a distinct type from bit so that bitfields
9505 convert as per ANSI C and bits retain their traditional
9506 boolean style behaviour. Implemented bitfield support in
9514 * src/ds390/gen.c: bit v bitfield split
9515 * src/z80/gen.c: New support for bitfields
9516 * support/regression/tests/bitfields.c: reenabled z80,
9519 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9521 Rules 246.x, 247.x relate to bitfields, the others speed up
9522 access to xdata mapped I/O devices.
9524 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9526 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9528 Cleaned up genPackBits and genUnpackBits and added two helper
9529 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9530 for literal assignments in genPackBits (thanks to Frieder for
9536 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9538 Fixed bug #748310 (pointer to function type mishandled when the
9539 function name is omitted). Also fixed a SIGSEGV when a function
9540 attribute (reentrant, etc) is used on a non-function or on a
9541 function but misplaced before the parameter list.
9543 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9545 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

9568 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9570 Made the constant following the "interrupt" keyword optional. If
9571 omitted, the function will not automatically be given an entry
9572 in the interrupt vector table (similar to #pragma NOIV, but
9573 less syntacticly kludgy). The interrupt number is also now
9574 range checked. Also fixed a bug in the high order bit example
9581 * support/Util/SDCCerr.c
9582 * support/Util/SDCCerr.h
9585 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

9588 * src/SDCCicode.c (operandOperation): rewritten some ops
9589 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9590 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9592 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9593 be re-activated by defining REDUCE_LITERALS)
9594 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9595 unsigned, but are signed by default
9596 * src/SDCCval.c (constVal): rearranged
9597 * src/SDCCval.c (valMod): preliminary fix
9598 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9641 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9642 * src/SDCCval.c (valDiv, valMod): fixed signdness
9643 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9644 signedness of modulo, left and right shift

10051 the regression tests I'm not brave enough to enable 245.b, 245.c
10052 * doc/sdccman.lyx: added latex preamble for hyperref package.
10053 Using pdflatex this will give you a hyperlinked pdf file with

10103 * src/SDCCmain.c: linkOptions is changed to set *,
10104 added if/endif conditional macros to remove options help
10105 messages from optionsTable when a port is not configured, added
10106 support for the PIc16 port in the ports table, when executing
10107 the compiler with no port specified on command line, a default
10108 port is selected with the new macro DEFAULT_PORT which is
10109 defined in port.h, in setDefaultOptions() linkOptions is removed
10110 from initialization assignment, since now it is a set,
10111 parseCmdLine uses setParseWithComma for linkOptions, in
10112 linkEdit() linkOptions are accessed with new function indexSet()
10113 which returns the i'th item of a set variable. See SDCCset.c, in
10114 linkEdit() when calling buildCmdLine(), added linkOptions as
10115 last argument. Now users can pass arguments to gplink via the
10116 -Wl option, main() uses pic16glue() to glue up pic16 programs

10128 * src/pic16/glue.c: commented out some error producing lines
10129 * src/pic16/main.c: __config directives are commented out to stop
10130 gpasm complaining and test the linkage with gplink, _linkCmd and
10131 _asmCmd changed to be more gplink and gpasm friendly
10132 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10133 produced an error when parsed, peep rule 12 is added to utilize
10134 movff, but it is commented out since the pCode does not support
10135 yet a command with 2 address arguments
10137 2003-05-18 <johan AT balder>
10139 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11197 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11198 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11200 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11202 * in /sdcc/as/mcs51/ changed these files in order to create an
11203 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11204 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11205 following files to include the previous two files: aslink.dsp,
11206 Makefile.aslink, Makefile.bcc, and Makefile.in.
11208 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11209 .adb instead of .cdb
11211 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11213 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11214 value from option --iram-size.
11216 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11218 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11221 2002-09-18 <wiml AT hhhh.org>
11223 * SDCClrange.h: exposed setFromRange() and setToRange()
11224 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11225 packRegsForAccUse() (bug 542397)
11226 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11227 multiple times and emitting the fetch operations more than once
11228 added aopGetUsesAcc() function to allow binary operators to
11229 fetch their operands in the correct order; made genMinus() emit
11230 compact code for X = LITERAL - Y
11232 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11233 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11234 sprintf() in line 1267.
11236 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11237 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11240 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11241 Changes to aslink (All the changes are marked with 'JCF'):
11243 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11246 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11247 area BSEG. Also moves, if possible, the DATA area down into the internal
11248 ram so more space is available.
11250 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11253 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11254 not bytes. Function summary() which creates a memory usage summary
11255 file with extension .mem. Reports of overlaping stack and small stack
11256 size. If the space for the stack is less than 16 bytes aslink trows a
11259 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11260 the 8051. Option 'y' for memory summary output file.
11262 Changes to sdcc (All the changes are marked with 'JCF'):
11264 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11266 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11267 overlaying area for it (uses RegBankUsed[4]).
11269 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11270 bank zero as used by default. By default aslink locates the stack
11271 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11272 the creation of the .mem file. Delegates the allocation of data area
11273 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11274 the begining of the stack area to aslink.
11276 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11277 glue() in SDCCglue.c creates an area for it.
11279 2002-09-03 Borut Razem <borut.razem AT siol.net>
11280 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11281 sdcc/src/pic/glue.c:
11282 introduced atexit() handler for teporay files removal in case of
11283 errors, assertions, ...
11285 2002-08-29 Borut Razem <borut.razem AT siol.net>
11286 * sdcc/support/cpp2/auto-host_vc_in.h:
11287 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11288 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11289 Maybe there is a similar problem with BORLANDC? It should be checked!
11291 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11292 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11293 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11294 was not executed, and the compiler (cl) launched a warning:
11295 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11297 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11298 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11300 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11301 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11303 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11304 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11305 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11306 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11307 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11308 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11309 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11310 - added Release configuration in VS projects
11311 - review of compiler an linker options
11312 - VC .exe files are generated in bin_vc directory, not to interfere
11313 with binaries generated from other projects (cygwin, mingw, bcc ...)
11315 * sdcc/src/yacc.dsp: added
11317 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11318 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11319 and insert the version number definitions from .version
11321 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11323 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11324 added - genarate auto-host.h using auto-host_vc_in.h as template
11327 removed from CVS, generated automatically
11329 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11330 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11332 2002-08-11 Borut Razem <borut.razem AT siol.net>
11333 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11335 2002-08-10 Borut Razem <borut.razem AT siol.net>
11336 * src/SDCCmain.c (main):
11337 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11338 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11339 The consequence was that some temporary files were not removed.
11342 unification of code in functions tempfilename() and tempfile():
11343 function tempnam() is defined in Visual Studio 6.0 and .NET
11345 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11347 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11348 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11349 - removed compiler command line option /WX: Treats all warnings as errors
11350 - update a list of source files, included into the project
11352 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11353 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11354 changed project type to Generic Project so that can be correcly converted to VS.NET project
11356 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11358 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11360 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11362 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11363 added return 0 statements after assert() to make compiler happy
11365 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11366 added newline in the def file to keep MSC compiler satisfied
11368 * sdcc/src/z80/gen.c:
11369 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11370 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11371 - solved MSC error in function aopDump()
11373 * sdcc_vc.h: define PREFIX as "\\sdcc"
11375 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11376 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11379 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11380 - Rewrote the register banking algorithm.
11381 - Added pCode live-range analysis to registers (for now, only non-used and
11382 singly-used registers optimized away)
11384 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11386 * 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.

11411 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11413 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11415 2002-03-28 Johan Knol <johan AT balder>
11417 * src/SDCCval.c: fixed bug #532436
11419 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11421 Added "char *Processor" field to the port structure.
11424 Added -p option. Allows port dependent processor to be specified.
11427 Initialized the new field char *Processor field to NULL in all ports
11430 Compiler generated registers for interrupt context saving
11431 were not getting allocated.
11433 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11436 Fixed left shift. Will promote the left side of a left shift
11437 if a) left shifting more than size of operand or b) when assigned
11438 to something size > size of left side
11440 2002-03-14 Scott Dattalo <scott AT dattalo.com>

11444 analysis is restructured. ...
11446 * src/pic/device.h:
11449 * src/pic/device.c:
11450 Added. device.c is a PIC port hack to accomodate variations
11453 2002-03-13 Michael Hope <michaelh AT vroom>
11455 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11457 2002-03-04 johanknol <johanknol AT manik>
11459 * /src/SDCCval.c: fixed
11461 const unsigned char arr[][2] = { { 0, 1 } };

11548 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11550 * sdcc/src/SDCCloop.c:
11551 Previous fix was not good. basic blocks that have "break" or "return" are
11552 not really partof a loop , but live ranges used in these blocks should
11553 be live thru the entire loop, so set partOfLoop but don't add them to
11556 2002-02-21 <johan AT FRIJA>
11558 * src/SDCCcse.c: fixed bug #514308
11560 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
