1327 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1329 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1330 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1332 One basic decision: e.g. src/clean.mk includes further files. In order
1333 to make this work there are two solutions:
1334 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1335 run configure on them. This way they can use
1336 'include $(srcdir)/port-clean.mk'
1337 - always include clean.mk by the Makefile at the same level. To avoid
1338 that `make clean` tries to include and build Makefile.dep the
1339 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1340 implemented, because now even `make uninstall` doesn't create
1341 Makefile.in. clean.mk could be eliminated by pasting it in
1344 * debugger/mcs51/Makefile.in: build own objects from library sources
1345 (SLIB, SDCC) in current directory
1347 * configure, configure.in: renamed --disable-device-lib-build in
1348 --disable-device-lib; added --enable-doc, the required tools are
1349 searched by configure; added result message; the toolchain for the
1350 belonging ports are now only built, if the port is enabled.
1352 * support/regression/*: all output is written in directory gen, because
1353 the fwk and ports directories don't livet in the build tree using vpath
1355 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1356 --disable-device-lib, added --enable-doc, added section VPATH

1610 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
1612 * src/mcs51/gen.c (genCall): fixed bug 1457608
1614 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

1633 implemented patch 1120823 Thanks to Willy De la Court (normal
1634 interrupts need an interrupt number now if they are made critical),
1635 and enabled nesting of critical functions though not for gbz80
1636 (genCritical, genEndCritical): added functions
1637 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1638 * src/z80/mappings.i: added "ei" to all mappings

1647 2006-03-16 Raphael Neider <rneider AT web.de>
1649 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1650 the left operand is shorter than the result (c* = lit-c* + int),
1652 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1655 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1657 * src/.version: increased version number to 2.5.5
1658 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1659 linking is done manually in pic16 port's _linkEdit,
1660 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1661 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1662 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1663 allocate asmop as AOP_ACC,
1664 (aopForRemat): added parameter 'bool result' in function declaration,
1665 (pic16_aopGet): return AOP_ACC when accessing WREG,
1666 (pic16_popGetTempReg): minor modification,

1677 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1678 call to allocReg, not by manually allocating a new one,
1679 (pic16_assignRegisters): now before going through the register
1680 allocating functions mark all registers as free. This eliminates some
1681 side effects resulting from peephole parser done earlier in the backbone
1683 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1731 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
1733 2006-03-06 Borut Razem <borut.razem AT siol.net>
1735 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1736 made the linker quiet
1738 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1740 * src/pic16/gen.c (genPcall): fixed bug #1443644
1741 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1742 which dumps before the function entry point a data byte which represents
1743 the number of the local variables used by the specified function, added
1744 'xinst' for initial support for Extended Instruction Support,
1745 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1746 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1747 port->fun_prefix anymore (may change later),
1748 (genFunction, genEndFunction): do not store/restore local registers for
1749 _main (this should take care the --main-return command line option in
1751 (genOr): removed some legacy pic-port instructions,
1752 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1753 performing operations with SFR's causes data to be written more than
1754 once to each SFR. Perhaps SFRs should be handled in special cases...
1755 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1757 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1758 into account for stack starting position,
1759 (struct OPTIONS pic16_optionsTable): added command line argument
1760 --extended or -y for Extended Instruction Support,
1761 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1762 (deassignLRs): *** perhaps the most important change, old 'for' code
1763 (commented out for reference), didn't account for some registers which
1764 were left marked 'not free' after a pointer operation. The change
1765 reduces register usage a lot in some cases
1767 2006-03-04 Borut Razem <borut.razem AT siol.net>
1769 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

4040 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4041 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4042 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4043 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4044 always available in leading double underscore form. The C99 support is
4045 mostly missing, but it's a start.
4046 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4047 reserved identifier "__data".

4125 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4127 * device/lib/printf_large.c: removed inline assembly for portability and
4128 readability. Use printf_fast if speed or size are more important.
4129 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4130 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4132 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4134 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4135 prevent compiler warning
4137 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4139 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4140 moved to level 0 and declared as static. Also they are explicit
4141 placed in access bank. This was necessery because some times they
4142 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4143 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4144 optimizations. Currently only compare to unsigned char is implemented,
4145 * src/pic16/gen.c: added fReturnIdx array,
4146 * (struct resolvedIfx) is moved to gen.h and made public,
4147 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4148 * (aopForSym): added an optimization to directly store in stack of
4149 the operand of a SEND iCode,
4150 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4151 but as registers instead (AOP_REG) using the fReturnIdx array,
4152 * (pic16_freeAsmop): remove the freed register from the
4153 _G.sregsAlloc field,
4154 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4155 a compare of 'WREG',
4156 * (pic16_popGetTempRegCond): changed function prototype, now
4157 function takes also a bitVector argument v which holds the current
4158 set of registers that are allocated for stack access by aopForSym,
4159 registers allocated in aopForSym for accessing stack symbols are not
4160 any more part of the functions usedRegs field,
4161 * (genCall): some times aopOp is called for a stack variable to be
4162 send, aopForSym might perform the push, if this is true make sure
4163 that genCall doesn't push the variable twice by testing _G.resDirect,
4164 * (genFunction): changed testing for unspecified interrupt number
4165 from 256 to INTNO_UNSPEC,
4166 * modified selection scheme of frame pointer generation. Previously
4167 if function did use local registers a frame pointer was generated,
4168 now a frame pointer is generated only if function has arguments
4169 (that need PLUSW2 register access), or has stack arguments, or the
4170 compiler is not instructed to omit the frame pointer,
4171 * (genEndFunction): before restoring local registers that were saved
4172 in the function preamble, also restore the registers that *might*
4173 have been allocated for stack access,
4174 * (genRet): removed some old comments,
4175 * (genCmp, the active (RN's) version): added a call to the
4176 pic16_genCmp_special function to perform the compare with a more
4177 robust and optimized way,
4178 * (genInline): a feature has been added in inline code generation,
4179 which allows a wildcard variable substitution when writing inline
4180 assembly. Code is incomplete and experimental therefore undocumented,
4181 * (genCast): changed order of aopOp for result and right to allow
4182 aopForSym to directly load the result if possible,
4183 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4184 perform an optimized compare on some selected special occasions,
4185 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4186 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4187 generate an IVT any more,
4188 * src/pic16/main.c (pic16_optionsTable): added command line option
4190 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4191 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4193 * src/pic16/NOTES: Raphael Neider added in list of active developers
4194 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4195 jumptable_end to prevent bug #,
4196 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4197 inCond and outCond fields,
4198 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4199 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4200 turn off register spilling,
4201 * (packRegsForOneUse): synced with other ports' versions although it
4202 is not used currently,
4203 * (pic16_packRegisters): added an optimization while reading
4204 structure bitfields, some registers may be saved (malloc code is
4205 decreased by 80 bytes)
4207 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4209 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4210 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4211 this can be optimized more?
4213 2005-03-10 Raphael Neider <rneider AT web.de>
4215 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4216 genNearPointerGet): (hopefully) fixed access to bitfields via
4217 pointers (p->bitN = x; and x = p->bitN; failed)
4219 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4263 to keep the correct label reference count when adding/removing references
4264 to labels. A peephole file using this is appended to patch #1144962.

4851 Adding support for replacing ljmps with sjmps in jumptables
4852 generated for switch statements. For now you need to set the
4853 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4854 Now 4 algorithms for mcs51 jumptable generation are used:
4855 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4856 addresses loaded pc-relative for up to 112 cases and stack-pushing
4857 target addresses loaded with offset from dptr for up to 256 cases.

4887 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4889 * added libc directory. The current version of LibC contains string
4890 functions, ctype functions and macros and some functions of the
4891 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4892 be extensively tested in the future. Standard disclaimer here.
4893 Library is not automatically build yet. But one can build it by
4894 invoking 'make' inside the libc directory.
4895 * added ADC library under libio. Preliminary version yet.

4905 * (pic16_storeForReturn): optimized return of 0,
4906 * (genCmp): experimental code for new genCmp which uses PIC18's
4907 special compare&skip instructions. Initial tests fail some times
4908 with variables grater than 1 byte in size, so new code is disabled,
4909 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4911 * (genCast): began a fix to optimize the casting of a bit to another
4912 bit, now assigning a bitfield to another bitfield will fail, sorry,
4913 * src/pic16/main.c: disabled the use of lr-support feature,
4914 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4921 and 1 for banking instruction,
4922 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4923 caused stop processing pCodes after a inline assembly block,
4924 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

4926 registers when it shouldn't,
4927 * src/pic16/ralloc.c (allocReg): add preliminary support for
4928 supporting a limited set of temporary registers,
4930 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7838 * support/regression/ports/ucz80/spec.mk (UCZ80): Made detect the
7841 * support/regression/generate-cases.py (main): Changed from inline
7844 * doc/Makefile (install): Changed to depth first to get rid of
7845 missing directory install warning.
7847 * as/Makefile (install-doc): Made work on Mac.
7849 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
7851 * src/SDCCast.c: added an additional type flow in decorateType() of
7852 opposite direction, see feature request #860006; it's enabled at runtime
7853 by setting the environment variable SDCC_NEWTYPEFLOW
7854 * src/SDCCast.h: changed prototype of decorateType()
7855 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
7856 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
7857 'char' to 'int' can be omitted, if both operands are 'unsigned char';
7858 see feature request #877103
7859 * src/SDCCval.c: updated call of decorateType()
7860 (valBitwise): fixed bug #882876
7861 (valMinus): added promotion
7862 (valLogicAndOr): result is unsigned
7863 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
7864 * src/SDCCsymt.c (computeType),
7865 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
7866 must not cause an unsigned operation
7867 * src/pic/glue (pic14emitRegularMap),
7868 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
7870 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>

7887 * src/pic/ralloc.h: applied patch from Slade Rich;
7888 added support for multiple code pages and multiple RAM banks on the
7889 PIC 14 port. The ASM files now no longer simply assume all the
7890 code / RAM are in the same page / bank. This means the linker can
7891 safely allocate code/RAM of separate ASM files to different pages/banks.
7892 * doc/sdccman.lyx: added Slade's tips
7893 * src/mcs51/peeph.def: fixed bug #880768

7902 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
7905 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
7906 strtof is not part of C89 and isn't included with Mac OS X.
7908 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7910 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

7935 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7937 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7938 loaded with the linker search paths (-L arguments) and the libraries
7939 to be linked with the current source (-l arguments). Changes
7940 currently will affect only the pic16 port.
7941 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7942 include path the port specific paths and port specific libraries,
7943 * gplink command now contains the $3 argument,
7944 * src/pic16/device.h,
7945 * src/pic16/device.c,: structure PIC_device is made public and
7946 renamed to PIC16_device, the same for variable Pics which is renamed

7961 Documenting changes from previous commits.
7962 * configure.in (version 1.56),
7963 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7964 when generating output files to configure the pic16 library,
7965 but now I've commented it out, since gputils aren't installed in the
7966 SF compile farm, so library won't compile
7968 * device/lib/Makefile.in (version 1.56): initially I've added in
7969 target 'all' the prerequestive 'model-pic16' so it compiled the
7970 pic16 library, but now I've commented it out for the same reasons
7972 * added targets 'model-pic16' and 'objects-pic16' to compile the
7974 * added target 'port-specific-objects-pic16' to handle the
7975 generated libraries and copy them into the build/ directory
7976 * added target 'clean-intermediate-pic16' to clean intermediate
7977 files into pic16 directory
7978 * in target 'installdirs' added line to create directory pic16 in
7979 the installation path
7981 * device/include/Makefile.in (version 1.11): in target 'install'
7982 added lines to copy all header files to installation path,
7983 * in target 'installdirs' added line create directory for pic16
7984 headers in the installation path

7999 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8000 option so that it actually works. Made it specific to the z80, since
8001 the gbz80 doesn't have these kinds of I/O ports.
8003 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8005 * device/include/z180.h,

8027 Mainly changes to support compilation of the device libraries
8028 * src/pic16/device.c: stack is allocated via symbol and not
8029 via literal number. The symbol is placed in the corresponding
8030 position of the data ram
8031 * (pic16_dump_section): relocatable and absolute uninitialized
8032 data are now emitted in sorted order to reduce section naming,
8033 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8034 weren't marked as being in the access bank,
8036 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8038 Added portion of GNU PIC Library under the directory
8039 device/include/pic16 and device/lib/pic16. These files
8040 contain the declarations of SFRs for the PIC18Fxx2 devices.
8041 The directory is initialized via configure from toplevel.
8043 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

8057 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
8059 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
8060 in simpler and even better code

8071 all over. Telling LaTeX to be less strict with word spacing
8072 to better keep the right margin. Changed some notes about
8073 maintainance of the ports in section 3.2.1 - is it OK like this?
8075 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8113 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8115 * src/pic16/peeph.def: all peepholes with movff are commented out,
8116 because there is a problem in the pcode peep optimizer,
8117 * src/pic16/ralloc.c: the register allocator can now reuse local

8256 Bug reported from Jesus Calvino-Fraga
8258 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8260 * sdcc.spec: updated
8261 * device/include/Makefile.in: don't install CVS directories

8264 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8265 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8266 * src/ds390/gen.c (genRightShift): fixed bug #870788
8267 * src/SDCCast.c (decorateType): fixed bug #870781
8269 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8271 PIC16 port related changes:
8272 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8273 added variable stackPos,
8275 * gen.c: genCall, assignResultValue: added support for
8276 pushing/retrieving function parameters to/from stack,
8277 genFunction,genEndFunction: setup stack frame for the
8279 genAddrOf: will be changed according to bug 863624
8281 * added files genutils.c and genutils.h which contain gen*
8282 debugged and optimised functions extracted from gen.c
8284 * glue.c: added variable 'externs' which holds extern symbols,
8285 pic16emitRegularMap: is modified to properly handle relocatable
8286 symbols under the new scheme,
8287 pic16createInterruptVect: is modified
8288 pic16printPublics: is modified to emit 'global' assembler directives,
8289 added pic16_printExterns to print extern symbols,
8290 pic16glue: initializes stack/frame pointer in the beginning of
8291 the assembly output. Temporary hack, will be corrected later,
8292 because gplink yet does not support stack and SDCC does not
8293 yet support a type of crt0.o object to create the final binary.
8295 * Removed many lines that contain 8051 legacy code.
8296 * The code is finally placed under a 'code' directive.
8297 * Added port specific options.
8299 * _process_pragma: simplified since now we do not need *special*
8300 include file to define SFR registers. But a separate header
8301 will be needed. This will be developed later.
8302 * _pic16_parseOptions: added, parses port specific options:
8303 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8304 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8305 --preplace-udata-with=
8307 * _pic16_setDefaultOptions: modified to initialize section names,
8308 but hack is temporarly out of order since it needs improvement.
8309 * _pic16_genAssemblerPreamble: configuration words are emitted by
8310 their address instead of their name. This part is incomplete and
8311 supports only the 18Fxx2 devices. Other devices will emit an error
8312 during assembly since they do not contain the same set of config
8314 * _pic16_genIVT: is modified,
8316 * pcode.c: added definitions for some hardware registers that are needed
8318 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8319 All PCI entries are updated. Now LFSR is supported.
8320 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8321 * added pic16_newpCodeOpLit2 to support instructions with
8322 two literal arguments
8323 * pic16_pCode2str: corrected code that emits assembler instructions
8324 with two literal operands and those that have an access bit modifier
8325 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8326 this fixes a bug which caused some labels to be lost, when an
8327 assembler directive was added, i.e. banksel,
8328 * pic16_FixRegisterBanking: improved logic that causes the insertion
8330 * InlineFunction: functions that are called once, are not any more
8331 inlined. This can be a port option in the future,
8333 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8335 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8336 hold the corresponding uninitialized symbols,
8337 * pic16_allocProcessorRegister: registers have explicit marked the
8339 * pic16_allocInternalRegister: registers are explicit marked as
8341 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8342 processing list, so bit registers were lost,
8345 * ralloc.h: added field 'accessBank' and original symbol operand
8346 in register definition,
8347 * removed the field isMapped from register definition,
8349 ** Several functions have been removed from various sources:
8350 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8351 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8352 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8353 pic16_assignRelocatableRegisters
8355 ** others have been introduced:
8356 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8357 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8359 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8361 * support/scripts/inc2h.pl: changed definition of BIT_AT
8362 to emit 'sbit at' instead of 'bit at'. This was a request.
8364 PIC16 port related preliminary changes:
8365 * gen.c: prefixed function popRegFromString with
8366 pic16_ and all references to it corrected
8367 * pcode.c: all pic16_pc_* hardware registers prefixed
8368 with underscore (_),
8369 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8370 * ralloc.c: newReg(): when register is REG_SFR then
8371 set address to rIdx,
8372 pic16_allocProcessorRegister(): marks register wasUsed=0
8373 pic16_writeUsedRegs(): added a call to assign processor
8374 registers via pic16_assignFixedRegisters
8376 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8378 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8379 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8380 variables in unused register banks. Also the SSEG is placed
8381 wherever there is enough space for it, and IDATA can be anywhere
8382 in internal RAM. For now compile using -Wl-Y[stack_size].
8383 The mem file is different for this option as well, since it
8384 makes no sense of talking about DSEG lenght.
8386 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8388 * src/SDCClrange.c: fixed bug 869095 that caused segfault

8633 * src/SDCCast.c (decorateType): disabled a transformation I added in
8634 revision 1.188 (access to fields of a structure at an absolute address);
8635 it breaks with bitfields, extern declarations, and gcse analysis.
8636 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8637 could be assigned through a pointer, so don't complain.

8745 xdata initialization slightly shorter
8747 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9394 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9395 fetching of the pointer
9396 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9397 copied from genNearPointerSet()
9398 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9399 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9400 If they pop r0/r1 they must be called in the opposite order than aopOp().
9401 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"

9413 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9415 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9416 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9417 type for bits was changed. It resulted in bit variables becoming
9418 global, which is not permitted in PIC 14 assembly output.
9420 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9422 * doc/sdccman.lyx: various additions and updates. Rearranged sections
9424 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9426 Z80 and MCS51 linkers complaint if a public symbol is defined
9427 in more than one library module:

9433 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9435 A few small changes that speed up the peephole optimizer.
9439 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9441 Try to make the peephole optimizer smarter by maintaining
9442 an association between the assembly source code and the
9443 iCodes that originated them. Put this information to use
9444 with a new peephole rule condition "notVolatile" so that
9445 the rules can be aggressive yet still safe.
9450 * src/mcs51/peeph.def
9452 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9456 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9457 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9458 if the left or right operand symbols have the accuse flag set.
9460 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9462 Changed the type of the result of the ! (NOT) operator to char;
9463 previously it returned the same type as the source. This allows
9464 us to eliminate all the genFloatNot functions (all of its target
9465 implementations were very buggy) since !float can use the same
9468 * src/SDCCicode.c (ast2iCode): ! returns char
9469 * src/mcs51/gen.c (genNot, genNotFloat),
9470 * src/ds390/gen.c (genNot, genNotFloat),
9471 * src/z80/gen.c (genNot, genNotFloat),
9472 * src/pic/gen.c (genNot, genNotFloat),
9473 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
9475 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
9477 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9478 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9479 during interrupts. Ensure WSAVE is located at a shared bank address.
9480 2. Fixed page selection in some places
9481 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9482 the registers name strings.
9483 4. Fixed "signed / unsigned compare" compiler warnings.
9484 5. The PIC port manages its own allocation of the general purpose
9485 registers, but makes no attempt to reuse them. As a result when
9486 compiling it soon runs out of general purpose registers. Some
9487 additional code was added to the files pcode.c and device.c to walk
9488 through the function call tree and rename the registers so that they
9498 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9499 genPlus() & genMinus() when the result is the same as left or right

9505 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9507 Made bitfield a distinct type from bit so that bitfields
9508 convert as per ANSI C and bits retain their traditional
9509 boolean style behaviour. Implemented bitfield support in
9517 * src/ds390/gen.c: bit v bitfield split
9518 * src/z80/gen.c: New support for bitfields
9519 * support/regression/tests/bitfields.c: reenabled z80,
9522 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9524 Rules 246.x, 247.x relate to bitfields, the others speed up
9525 access to xdata mapped I/O devices.
9527 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9529 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9531 Cleaned up genPackBits and genUnpackBits and added two helper
9532 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9533 for literal assignments in genPackBits (thanks to Frieder for
9539 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9541 Fixed bug #748310 (pointer to function type mishandled when the
9542 function name is omitted). Also fixed a SIGSEGV when a function
9543 attribute (reentrant, etc) is used on a non-function or on a
9544 function but misplaced before the parameter list.
9546 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9548 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9549 * support/Util/SDCCerr.h,

9571 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9573 Made the constant following the "interrupt" keyword optional. If
9574 omitted, the function will not automatically be given an entry
9575 in the interrupt vector table (similar to #pragma NOIV, but
9576 less syntacticly kludgy). The interrupt number is also now
9577 range checked. Also fixed a bug in the high order bit example
9584 * support/Util/SDCCerr.c
9585 * support/Util/SDCCerr.h
9588 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

9591 * src/SDCCicode.c (operandOperation): rewritten some ops
9592 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9593 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9595 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9596 be re-activated by defining REDUCE_LITERALS)
9597 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9598 unsigned, but are signed by default
9599 * src/SDCCval.c (constVal): rearranged
9600 * src/SDCCval.c (valMod): preliminary fix
9601 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9644 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9645 * src/SDCCval.c (valDiv, valMod): fixed signdness
9646 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9647 signedness of modulo, left and right shift

10054 the regression tests I'm not brave enough to enable 245.b, 245.c
10055 * doc/sdccman.lyx: added latex preamble for hyperref package.
10056 Using pdflatex this will give you a hyperlinked pdf file with

10098 it can be defined with CFLAGS when running configure
10099 * src/SDCCmain.c: fixed compiling + linking with object files
10101 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

10106 * src/SDCCmain.c: linkOptions is changed to set *,
10107 added if/endif conditional macros to remove options help
10108 messages from optionsTable when a port is not configured, added
10109 support for the PIc16 port in the ports table, when executing
10110 the compiler with no port specified on command line, a default
10111 port is selected with the new macro DEFAULT_PORT which is
10112 defined in port.h, in setDefaultOptions() linkOptions is removed
10113 from initialization assignment, since now it is a set,
10114 parseCmdLine uses setParseWithComma for linkOptions, in
10115 linkEdit() linkOptions are accessed with new function indexSet()
10116 which returns the i'th item of a set variable. See SDCCset.c, in
10117 linkEdit() when calling buildCmdLine(), added linkOptions as
10118 last argument. Now users can pass arguments to gplink via the
10119 -Wl option, main() uses pic16glue() to glue up pic16 programs

10131 * src/pic16/glue.c: commented out some error producing lines
10132 * src/pic16/main.c: __config directives are commented out to stop
10133 gpasm complaining and test the linkage with gplink, _linkCmd and
10134 _asmCmd changed to be more gplink and gpasm friendly
10135 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10136 produced an error when parsed, peep rule 12 is added to utilize
10137 movff, but it is commented out since the pCode does not support
10138 yet a command with 2 address arguments
10140 2003-05-18 <johan AT balder>
10142 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11198 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11200 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11201 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11203 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11205 * in /sdcc/as/mcs51/ changed these files in order to create an
11206 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11207 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11208 following files to include the previous two files: aslink.dsp,
11209 Makefile.aslink, Makefile.bcc, and Makefile.in.
11211 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11212 .adb instead of .cdb
11214 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11216 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11217 value from option --iram-size.
11219 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11221 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11224 2002-09-18 <wiml AT hhhh.org>
11226 * SDCClrange.h: exposed setFromRange() and setToRange()
11227 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11228 packRegsForAccUse() (bug 542397)
11229 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11230 multiple times and emitting the fetch operations more than once
11231 added aopGetUsesAcc() function to allow binary operators to
11232 fetch their operands in the correct order; made genMinus() emit
11233 compact code for X = LITERAL - Y
11235 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11236 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11237 sprintf() in line 1267.
11239 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11240 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11243 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11244 Changes to aslink (All the changes are marked with 'JCF'):
11246 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11249 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11250 area BSEG. Also moves, if possible, the DATA area down into the internal
11251 ram so more space is available.
11253 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11256 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11257 not bytes. Function summary() which creates a memory usage summary
11258 file with extension .mem. Reports of overlaping stack and small stack
11259 size. If the space for the stack is less than 16 bytes aslink trows a
11262 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11263 the 8051. Option 'y' for memory summary output file.
11265 Changes to sdcc (All the changes are marked with 'JCF'):
11267 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11269 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11270 overlaying area for it (uses RegBankUsed[4]).
11272 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11273 bank zero as used by default. By default aslink locates the stack
11274 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11275 the creation of the .mem file. Delegates the allocation of data area
11276 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11277 the begining of the stack area to aslink.
11279 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11280 glue() in SDCCglue.c creates an area for it.
11282 2002-09-03 Borut Razem <borut.razem AT siol.net>
11283 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11284 sdcc/src/pic/glue.c:
11285 introduced atexit() handler for teporay files removal in case of
11286 errors, assertions, ...
11288 2002-08-29 Borut Razem <borut.razem AT siol.net>
11289 * sdcc/support/cpp2/auto-host_vc_in.h:
11290 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11291 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11292 Maybe there is a similar problem with BORLANDC? It should be checked!
11294 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11295 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11296 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11297 was not executed, and the compiler (cl) launched a warning:
11298 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11300 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11301 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11303 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11304 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11306 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11307 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11308 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11309 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11310 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11311 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11312 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11313 - added Release configuration in VS projects
11314 - review of compiler an linker options
11315 - VC .exe files are generated in bin_vc directory, not to interfere
11316 with binaries generated from other projects (cygwin, mingw, bcc ...)
11318 * sdcc/src/yacc.dsp: added
11320 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11321 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11322 and insert the version number definitions from .version
11324 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11326 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11327 added - genarate auto-host.h using auto-host_vc_in.h as template
11330 removed from CVS, generated automatically
11332 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11333 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11335 2002-08-11 Borut Razem <borut.razem AT siol.net>
11336 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11338 2002-08-10 Borut Razem <borut.razem AT siol.net>
11339 * src/SDCCmain.c (main):
11340 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11341 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11342 The consequence was that some temporary files were not removed.
11345 unification of code in functions tempfilename() and tempfile():
11346 function tempnam() is defined in Visual Studio 6.0 and .NET
11348 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11350 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11351 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11352 - removed compiler command line option /WX: Treats all warnings as errors
11353 - update a list of source files, included into the project
11355 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11356 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11357 changed project type to Generic Project so that can be correcly converted to VS.NET project
11359 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11361 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11363 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11365 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11366 added return 0 statements after assert() to make compiler happy
11368 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11369 added newline in the def file to keep MSC compiler satisfied
11371 * sdcc/src/z80/gen.c:
11372 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11373 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11374 - solved MSC error in function aopDump()
11376 * sdcc_vc.h: define PREFIX as "\\sdcc"
11378 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11379 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11382 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11383 - Rewrote the register banking algorithm.
11384 - Added pCode live-range analysis to registers (for now, only non-used and
11385 singly-used registers optimized away)
11387 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11389 * 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.

11412 * src/z80/main.c: Added force callee saves for jaune.
11414 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11416 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11418 2002-03-28 Johan Knol <johan AT balder>
11420 * src/SDCCval.c: fixed bug #532436
11422 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11424 Added "char *Processor" field to the port structure.
11427 Added -p option. Allows port dependent processor to be specified.
11430 Initialized the new field char *Processor field to NULL in all ports
11433 Compiler generated registers for interrupt context saving
11434 were not getting allocated.
11436 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11439 Fixed left shift. Will promote the left side of a left shift
11440 if a) left shifting more than size of operand or b) when assigned
11441 to something size > size of left side
11443 2002-03-14 Scott Dattalo <scott AT dattalo.com>

11447 analysis is restructured. ...
11449 * src/pic/device.h:
11452 * src/pic/device.c:
11453 Added. device.c is a PIC port hack to accomodate variations
11456 2002-03-13 Michael Hope <michaelh AT vroom>
11458 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11460 2002-03-04 johanknol <johanknol AT manik>
11462 * /src/SDCCval.c: fixed

11551 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11553 * sdcc/src/SDCCloop.c:
11554 Previous fix was not good. basic blocks that have "break" or "return" are
11555 not really partof a loop , but live ranges used in these blocks should
11556 be live thru the entire loop, so set partOfLoop but don't add them to
11559 2002-02-21 <johan AT FRIJA>
11561 * src/SDCCcse.c: fixed bug #514308
11563 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
11566 Fixed BUG #519583. If a conditional block ended in a return/break
