1314 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1316 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1317 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1319 One basic decision: e.g. src/clean.mk includes further files. In order
1320 to make this work there are two solutions:
1321 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1322 run configure on them. This way they can use
1323 'include $(srcdir)/port-clean.mk'
1324 - always include clean.mk by the Makefile at the same level. To avoid
1325 that `make clean` tries to include and build Makefile.dep the
1326 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1327 implemented, because now even `make uninstall` doesn't create
1328 Makefile.in. clean.mk could be eliminated by pasting it in
1331 * debugger/mcs51/Makefile.in: build own objects from library sources
1332 (SLIB, SDCC) in current directory
1334 * configure, configure.in: renamed --disable-device-lib-build in
1335 --disable-device-lib; added --enable-doc, the required tools are
1336 searched by configure; added result message; the toolchain for the
1337 belonging ports are now only built, if the port is enabled.
1339 * support/regression/*: all output is written in directory gen, because
1340 the fwk and ports directories don't livet in the build tree using vpath
1342 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1343 --disable-device-lib, added --enable-doc, added section VPATH
1345 * sim/ucsim/configure.in,
1346 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1347 z80 are enabled by default
1349 2006-04-24 Raphael Neider <rneider AT web.de>
1351 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1352 to config word, "pic14_"-prefixed some extern functions
1353 (pic14_emitConfigWord): emit __config directive(s) if assignment to

1620 implemented patch 1120823 Thanks to Willy De la Court (normal
1621 interrupts need an interrupt number now if they are made critical),
1622 and enabled nesting of critical functions though not for gbz80
1623 (genCritical, genEndCritical): added functions
1624 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1625 * src/z80/mappings.i: added "ei" to all mappings

1634 2006-03-16 Raphael Neider <rneider AT web.de>
1636 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1637 the left operand is shorter than the result (c* = lit-c* + int),
1639 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1642 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1644 * src/.version: increased version number to 2.5.5
1645 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1646 linking is done manually in pic16 port's _linkEdit,
1647 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1648 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1649 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1650 allocate asmop as AOP_ACC,
1651 (aopForRemat): added parameter 'bool result' in function declaration,
1652 (pic16_aopGet): return AOP_ACC when accessing WREG,
1653 (pic16_popGetTempReg): minor modification,

1664 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1665 call to allocReg, not by manually allocating a new one,
1666 (pic16_assignRegisters): now before going through the register
1667 allocating functions mark all registers as free. This eliminates some
1668 side effects resulting from peephole parser done earlier in the backbone
1670 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1720 2006-03-06 Borut Razem <borut.razem AT siol.net>
1722 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1723 made the linker quiet
1725 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1727 * src/pic16/gen.c (genPcall): fixed bug #1443644
1728 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1729 which dumps before the function entry point a data byte which represents
1730 the number of the local variables used by the specified function, added
1731 'xinst' for initial support for Extended Instruction Support,
1732 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1733 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1734 port->fun_prefix anymore (may change later),
1735 (genFunction, genEndFunction): do not store/restore local registers for
1736 _main (this should take care the --main-return command line option in
1738 (genOr): removed some legacy pic-port instructions,
1739 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1740 performing operations with SFR's causes data to be written more than
1741 once to each SFR. Perhaps SFRs should be handled in special cases...
1742 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1744 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1745 into account for stack starting position,
1746 (struct OPTIONS pic16_optionsTable): added command line argument
1747 --extended or -y for Extended Instruction Support,
1748 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1749 (deassignLRs): *** perhaps the most important change, old 'for' code
1750 (commented out for reference), didn't account for some registers which
1751 were left marked 'not free' after a pointer operation. The change
1752 reduces register usage a lot in some cases
1754 2006-03-04 Borut Razem <borut.razem AT siol.net>
1756 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

4029 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4030 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4031 always available in leading double underscore form. The C99 support is
4032 mostly missing, but it's a start.
4033 * support/regression/tests/bug-227710.c: fixed nonconforming use of

4112 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4114 * device/lib/printf_large.c: removed inline assembly for portability and
4115 readability. Use printf_fast if speed or size are more important.
4116 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4117 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4119 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4121 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4122 prevent compiler warning
4124 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4126 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4127 moved to level 0 and declared as static. Also they are explicit
4128 placed in access bank. This was necessery because some times they
4129 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4130 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4131 optimizations. Currently only compare to unsigned char is implemented,
4132 * src/pic16/gen.c: added fReturnIdx array,
4133 * (struct resolvedIfx) is moved to gen.h and made public,
4134 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4135 * (aopForSym): added an optimization to directly store in stack of
4136 the operand of a SEND iCode,
4137 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4138 but as registers instead (AOP_REG) using the fReturnIdx array,
4139 * (pic16_freeAsmop): remove the freed register from the
4140 _G.sregsAlloc field,
4141 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4142 a compare of 'WREG',
4143 * (pic16_popGetTempRegCond): changed function prototype, now
4144 function takes also a bitVector argument v which holds the current
4145 set of registers that are allocated for stack access by aopForSym,
4146 registers allocated in aopForSym for accessing stack symbols are not
4147 any more part of the functions usedRegs field,
4148 * (genCall): some times aopOp is called for a stack variable to be
4149 send, aopForSym might perform the push, if this is true make sure
4150 that genCall doesn't push the variable twice by testing _G.resDirect,
4151 * (genFunction): changed testing for unspecified interrupt number
4152 from 256 to INTNO_UNSPEC,
4153 * modified selection scheme of frame pointer generation. Previously
4154 if function did use local registers a frame pointer was generated,
4155 now a frame pointer is generated only if function has arguments
4156 (that need PLUSW2 register access), or has stack arguments, or the
4157 compiler is not instructed to omit the frame pointer,
4158 * (genEndFunction): before restoring local registers that were saved
4159 in the function preamble, also restore the registers that *might*
4160 have been allocated for stack access,
4161 * (genRet): removed some old comments,
4162 * (genCmp, the active (RN's) version): added a call to the
4163 pic16_genCmp_special function to perform the compare with a more
4164 robust and optimized way,
4165 * (genInline): a feature has been added in inline code generation,
4166 which allows a wildcard variable substitution when writing inline
4167 assembly. Code is incomplete and experimental therefore undocumented,
4168 * (genCast): changed order of aopOp for result and right to allow
4169 aopForSym to directly load the result if possible,
4170 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4171 perform an optimized compare on some selected special occasions,
4172 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4173 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4174 generate an IVT any more,
4175 * src/pic16/main.c (pic16_optionsTable): added command line option
4177 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4178 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4180 * src/pic16/NOTES: Raphael Neider added in list of active developers
4181 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4182 jumptable_end to prevent bug #,
4183 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4184 inCond and outCond fields,
4185 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4186 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4187 turn off register spilling,
4188 * (packRegsForOneUse): synced with other ports' versions although it
4189 is not used currently,
4190 * (pic16_packRegisters): added an optimization while reading
4191 structure bitfields, some registers may be saved (malloc code is
4192 decreased by 80 bytes)
4194 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4196 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4197 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4198 this can be optimized more?
4200 2005-03-10 Raphael Neider <rneider AT web.de>
4202 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4203 genNearPointerGet): (hopefully) fixed access to bitfields via
4204 pointers (p->bitN = x; and x = p->bitN; failed)
4206 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4838 Adding support for replacing ljmps with sjmps in jumptables
4839 generated for switch statements. For now you need to set the
4840 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4841 Now 4 algorithms for mcs51 jumptable generation are used:
4842 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4843 addresses loaded pc-relative for up to 112 cases and stack-pushing
4844 target addresses loaded with offset from dptr for up to 256 cases.

4871 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4872 to call when a stack overflow occurs,
4873 * (malloc.h): added CVS Id tag,
4874 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4876 * added libc directory. The current version of LibC contains string
4877 functions, ctype functions and macros and some functions of the
4878 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4879 be extensively tested in the future. Standard disclaimer here.
4880 Library is not automatically build yet. But one can build it by
4881 invoking 'make' inside the libc directory.
4882 * added ADC library under libio. Preliminary version yet.
4884 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

4888 temporary registers, its a buggy feature and will be removed,
4889 * (pic16_popGet): set register instance field in AOP_CRY,
4890 * (pic16_outBitC): fixed for results in size greater than 1,
4891 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4892 * (pic16_storeForReturn): optimized return of 0,
4893 * (genCmp): experimental code for new genCmp which uses PIC18's
4894 special compare&skip instructions. Initial tests fail some times
4895 with variables grater than 1 byte in size, so new code is disabled,
4896 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4898 * (genCast): began a fix to optimize the casting of a bit to another
4899 bit, now assigning a bitfield to another bitfield will fail, sorry,
4900 * src/pic16/main.c: disabled the use of lr-support feature,
4901 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4904 bits with offset (case PO_GPR_BIT),
4905 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4907 * (isBankInstruction): modified to return 0 for no banking instruction,
4908 and 1 for banking instruction,
4909 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4910 caused stop processing pCodes after a inline assembly block,
4911 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4912 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4913 registers when it shouldn't,
4914 * src/pic16/ralloc.c (allocReg): add preliminary support for
4915 supporting a limited set of temporary registers,
4917 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4919 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4920 genDataPointerSet): ensure assignments always copy in MSB to LSB
4922 (loadRegFromAop): recognize CLRH optimization,
4923 (genFunction): optimize RECEIVE iCodes in reentrant functions
4925 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7842 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
7843 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
7844 'char' to 'int' can be omitted, if both operands are 'unsigned char';
7845 see feature request #877103
7846 * src/SDCCval.c: updated call of decorateType()
7847 (valBitwise): fixed bug #882876
7848 (valMinus): added promotion
7849 (valLogicAndOr): result is unsigned
7850 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
7851 * src/SDCCsymt.c (computeType),
7852 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
7853 must not cause an unsigned operation
7854 * src/pic/glue (pic14emitRegularMap),
7855 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
7857 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>

7874 * src/pic/ralloc.h: applied patch from Slade Rich;
7875 added support for multiple code pages and multiple RAM banks on the
7876 PIC 14 port. The ASM files now no longer simply assume all the
7877 code / RAM are in the same page / bank. This means the linker can
7878 safely allocate code/RAM of separate ASM files to different pages/banks.
7879 * doc/sdccman.lyx: added Slade's tips
7880 * src/mcs51/peeph.def: fixed bug #880768

7889 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
7892 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
7893 strtof is not part of C89 and isn't included with Mac OS X.
7895 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7897 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

7922 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7924 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7925 loaded with the linker search paths (-L arguments) and the libraries
7926 to be linked with the current source (-l arguments). Changes
7927 currently will affect only the pic16 port.
7928 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7929 include path the port specific paths and port specific libraries,
7930 * gplink command now contains the $3 argument,
7931 * src/pic16/device.h,
7932 * src/pic16/device.c,: structure PIC_device is made public and
7933 renamed to PIC16_device, the same for variable Pics which is renamed

7946 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
7948 Documenting changes from previous commits.
7949 * configure.in (version 1.56),
7950 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7951 when generating output files to configure the pic16 library,
7952 but now I've commented it out, since gputils aren't installed in the
7953 SF compile farm, so library won't compile
7955 * device/lib/Makefile.in (version 1.56): initially I've added in
7956 target 'all' the prerequestive 'model-pic16' so it compiled the
7957 pic16 library, but now I've commented it out for the same reasons
7959 * added targets 'model-pic16' and 'objects-pic16' to compile the
7961 * added target 'port-specific-objects-pic16' to handle the
7962 generated libraries and copy them into the build/ directory
7963 * added target 'clean-intermediate-pic16' to clean intermediate
7964 files into pic16 directory
7965 * in target 'installdirs' added line to create directory pic16 in
7966 the installation path
7968 * device/include/Makefile.in (version 1.11): in target 'install'
7969 added lines to copy all header files to installation path,
7970 * in target 'installdirs' added line create directory for pic16
7971 headers in the installation path

7986 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7987 option so that it actually works. Made it specific to the z80, since
7988 the gbz80 doesn't have these kinds of I/O ports.
7990 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7992 * device/include/z180.h,

8014 Mainly changes to support compilation of the device libraries
8015 * src/pic16/device.c: stack is allocated via symbol and not
8016 via literal number. The symbol is placed in the corresponding
8017 position of the data ram
8018 * (pic16_dump_section): relocatable and absolute uninitialized
8019 data are now emitted in sorted order to reduce section naming,
8020 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8021 weren't marked as being in the access bank,
8023 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8025 Added portion of GNU PIC Library under the directory
8026 device/include/pic16 and device/lib/pic16. These files
8027 contain the declarations of SFRs for the PIC18Fxx2 devices.
8028 The directory is initialized via configure from toplevel.
8030 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
8032 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

8044 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
8046 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
8047 in simpler and even better code

8058 all over. Telling LaTeX to be less strict with word spacing
8059 to better keep the right margin. Changed some notes about
8060 maintainance of the ports in section 3.2.1 - is it OK like this?
8062 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8100 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8102 * src/pic16/peeph.def: all peepholes with movff are commented out,
8103 because there is a problem in the pcode peep optimizer,
8104 * src/pic16/ralloc.c: the register allocator can now reuse local

8243 Bug reported from Jesus Calvino-Fraga
8245 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8247 * sdcc.spec: updated

8256 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8258 PIC16 port related changes:
8259 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8260 added variable stackPos,
8262 * gen.c: genCall, assignResultValue: added support for
8263 pushing/retrieving function parameters to/from stack,
8264 genFunction,genEndFunction: setup stack frame for the
8266 genAddrOf: will be changed according to bug 863624
8268 * added files genutils.c and genutils.h which contain gen*
8269 debugged and optimised functions extracted from gen.c
8271 * glue.c: added variable 'externs' which holds extern symbols,
8272 pic16emitRegularMap: is modified to properly handle relocatable
8273 symbols under the new scheme,
8274 pic16createInterruptVect: is modified
8275 pic16printPublics: is modified to emit 'global' assembler directives,
8276 added pic16_printExterns to print extern symbols,
8277 pic16glue: initializes stack/frame pointer in the beginning of
8278 the assembly output. Temporary hack, will be corrected later,
8279 because gplink yet does not support stack and SDCC does not
8280 yet support a type of crt0.o object to create the final binary.
8282 * Removed many lines that contain 8051 legacy code.
8283 * The code is finally placed under a 'code' directive.
8284 * Added port specific options.
8286 * _process_pragma: simplified since now we do not need *special*
8287 include file to define SFR registers. But a separate header
8288 will be needed. This will be developed later.
8289 * _pic16_parseOptions: added, parses port specific options:
8290 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8291 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8292 --preplace-udata-with=
8294 * _pic16_setDefaultOptions: modified to initialize section names,
8295 but hack is temporarly out of order since it needs improvement.
8296 * _pic16_genAssemblerPreamble: configuration words are emitted by
8297 their address instead of their name. This part is incomplete and
8298 supports only the 18Fxx2 devices. Other devices will emit an error
8299 during assembly since they do not contain the same set of config
8301 * _pic16_genIVT: is modified,
8303 * pcode.c: added definitions for some hardware registers that are needed
8305 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8306 All PCI entries are updated. Now LFSR is supported.
8307 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8308 * added pic16_newpCodeOpLit2 to support instructions with
8309 two literal arguments
8310 * pic16_pCode2str: corrected code that emits assembler instructions
8311 with two literal operands and those that have an access bit modifier
8312 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8313 this fixes a bug which caused some labels to be lost, when an
8314 assembler directive was added, i.e. banksel,
8315 * pic16_FixRegisterBanking: improved logic that causes the insertion
8317 * InlineFunction: functions that are called once, are not any more
8318 inlined. This can be a port option in the future,
8320 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8322 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8323 hold the corresponding uninitialized symbols,
8324 * pic16_allocProcessorRegister: registers have explicit marked the
8326 * pic16_allocInternalRegister: registers are explicit marked as
8328 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8329 processing list, so bit registers were lost,
8332 * ralloc.h: added field 'accessBank' and original symbol operand
8333 in register definition,
8334 * removed the field isMapped from register definition,
8336 ** Several functions have been removed from various sources:
8337 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,

8346 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8348 * support/scripts/inc2h.pl: changed definition of BIT_AT
8349 to emit 'sbit at' instead of 'bit at'. This was a request.
8351 PIC16 port related preliminary changes:
8352 * gen.c: prefixed function popRegFromString with
8353 pic16_ and all references to it corrected
8354 * pcode.c: all pic16_pc_* hardware registers prefixed
8355 with underscore (_),
8356 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8357 * ralloc.c: newReg(): when register is REG_SFR then
8358 set address to rIdx,
8359 pic16_allocProcessorRegister(): marks register wasUsed=0
8360 pic16_writeUsedRegs(): added a call to assign processor
8361 registers via pic16_assignFixedRegisters
8363 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8365 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8366 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8367 variables in unused register banks. Also the SSEG is placed
8368 wherever there is enough space for it, and IDATA can be anywhere
8369 in internal RAM. For now compile using -Wl-Y[stack_size].
8370 The mem file is different for this option as well, since it
8371 makes no sense of talking about DSEG lenght.
8373 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8375 * src/SDCClrange.c: fixed bug 869095 that caused segfault

8622 it breaks with bitfields, extern declarations, and gcse analysis.
8623 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8624 could be assigned through a pointer, so don't complain.

9368 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
9369 iCode properly now. Use getSize instead of nRegs since a & b
9370 aren't part of the nRegs tally.
9372 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
9374 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

9380 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9381 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9382 fetching of the pointer
9383 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9384 copied from genNearPointerSet()
9385 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9386 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9387 If they pop r0/r1 they must be called in the opposite order than aopOp().
9388 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9389 (resp. --stack-auto), prepared for --xstack

9400 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9402 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9403 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9404 type for bits was changed. It resulted in bit variables becoming
9405 global, which is not permitted in PIC 14 assembly output.
9407 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9409 * doc/sdccman.lyx: various additions and updates. Rearranged sections
9411 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9413 Z80 and MCS51 linkers complaint if a public symbol is defined

9422 A few small changes that speed up the peephole optimizer.
9426 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9428 Try to make the peephole optimizer smarter by maintaining
9429 an association between the assembly source code and the
9430 iCodes that originated them. Put this information to use
9431 with a new peephole rule condition "notVolatile" so that
9432 the rules can be aggressive yet still safe.
9437 * src/mcs51/peeph.def
9439 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9443 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9444 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9445 if the left or right operand symbols have the accuse flag set.
9447 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9449 Changed the type of the result of the ! (NOT) operator to char;
9450 previously it returned the same type as the source. This allows
9451 us to eliminate all the genFloatNot functions (all of its target
9452 implementations were very buggy) since !float can use the same
9455 * src/SDCCicode.c (ast2iCode): ! returns char
9456 * src/mcs51/gen.c (genNot, genNotFloat),
9457 * src/ds390/gen.c (genNot, genNotFloat),
9458 * src/z80/gen.c (genNot, genNotFloat),
9459 * src/pic/gen.c (genNot, genNotFloat),
9460 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
9462 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
9464 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9465 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9466 during interrupts. Ensure WSAVE is located at a shared bank address.
9467 2. Fixed page selection in some places
9468 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9469 the registers name strings.
9470 4. Fixed "signed / unsigned compare" compiler warnings.
9471 5. The PIC port manages its own allocation of the general purpose
9472 registers, but makes no attempt to reuse them. As a result when
9473 compiling it soon runs out of general purpose registers. Some
9474 additional code was added to the files pcode.c and device.c to walk
9475 through the function call tree and rename the registers so that they
9485 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9486 genPlus() & genMinus() when the result is the same as left or right

9492 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9494 Made bitfield a distinct type from bit so that bitfields
9495 convert as per ANSI C and bits retain their traditional
9496 boolean style behaviour. Implemented bitfield support in
9504 * src/ds390/gen.c: bit v bitfield split
9505 * src/z80/gen.c: New support for bitfields
9506 * support/regression/tests/bitfields.c: reenabled z80,
9509 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9511 Rules 246.x, 247.x relate to bitfields, the others speed up
9512 access to xdata mapped I/O devices.
9514 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9516 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9518 Cleaned up genPackBits and genUnpackBits and added two helper
9519 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9520 for literal assignments in genPackBits (thanks to Frieder for
9526 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9528 Fixed bug #748310 (pointer to function type mishandled when the
9529 function name is omitted). Also fixed a SIGSEGV when a function
9530 attribute (reentrant, etc) is used on a non-function or on a
9531 function but misplaced before the parameter list.
9533 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9535 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

9558 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9560 Made the constant following the "interrupt" keyword optional. If
9561 omitted, the function will not automatically be given an entry
9562 in the interrupt vector table (similar to #pragma NOIV, but
9563 less syntacticly kludgy). The interrupt number is also now
9564 range checked. Also fixed a bug in the high order bit example
9571 * support/Util/SDCCerr.c
9572 * support/Util/SDCCerr.h
9575 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

9578 * src/SDCCicode.c (operandOperation): rewritten some ops
9579 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9580 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9582 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9583 be re-activated by defining REDUCE_LITERALS)
9584 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9585 unsigned, but are signed by default
9586 * src/SDCCval.c (constVal): rearranged
9587 * src/SDCCval.c (valMod): preliminary fix
9588 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10041 the regression tests I'm not brave enough to enable 245.b, 245.c
10042 * doc/sdccman.lyx: added latex preamble for hyperref package.
10043 Using pdflatex this will give you a hyperlinked pdf file with

10094 added if/endif conditional macros to remove options help
10095 messages from optionsTable when a port is not configured, added
10096 support for the PIc16 port in the ports table, when executing
10097 the compiler with no port specified on command line, a default
10098 port is selected with the new macro DEFAULT_PORT which is
10099 defined in port.h, in setDefaultOptions() linkOptions is removed
10100 from initialization assignment, since now it is a set,
10101 parseCmdLine uses setParseWithComma for linkOptions, in
10102 linkEdit() linkOptions are accessed with new function indexSet()
10103 which returns the i'th item of a set variable. See SDCCset.c, in
10104 linkEdit() when calling buildCmdLine(), added linkOptions as
10105 last argument. Now users can pass arguments to gplink via the
10106 -Wl option, main() uses pic16glue() to glue up pic16 programs

10118 * src/pic16/glue.c: commented out some error producing lines
10119 * src/pic16/main.c: __config directives are commented out to stop
10120 gpasm complaining and test the linkage with gplink, _linkCmd and
10121 _asmCmd changed to be more gplink and gpasm friendly
10122 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10123 produced an error when parsed, peep rule 12 is added to utilize
10124 movff, but it is commented out since the pCode does not support
10125 yet a command with 2 address arguments
10127 2003-05-18 <johan AT balder>
10129 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11194 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11195 following files to include the previous two files: aslink.dsp,
11196 Makefile.aslink, Makefile.bcc, and Makefile.in.
11198 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11199 .adb instead of .cdb
11201 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11203 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11204 value from option --iram-size.
11206 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11208 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11211 2002-09-18 <wiml AT hhhh.org>
11213 * SDCClrange.h: exposed setFromRange() and setToRange()
11214 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11215 packRegsForAccUse() (bug 542397)
11216 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11217 multiple times and emitting the fetch operations more than once
11218 added aopGetUsesAcc() function to allow binary operators to
11219 fetch their operands in the correct order; made genMinus() emit
11220 compact code for X = LITERAL - Y
11222 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11223 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11224 sprintf() in line 1267.
11226 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11227 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11230 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11231 Changes to aslink (All the changes are marked with 'JCF'):
11233 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11236 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11237 area BSEG. Also moves, if possible, the DATA area down into the internal
11238 ram so more space is available.
11240 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11243 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11244 not bytes. Function summary() which creates a memory usage summary
11245 file with extension .mem. Reports of overlaping stack and small stack
11246 size. If the space for the stack is less than 16 bytes aslink trows a
11249 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11250 the 8051. Option 'y' for memory summary output file.
11252 Changes to sdcc (All the changes are marked with 'JCF'):
11254 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11256 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11257 overlaying area for it (uses RegBankUsed[4]).
11259 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11260 bank zero as used by default. By default aslink locates the stack
11261 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11262 the creation of the .mem file. Delegates the allocation of data area
11263 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11264 the begining of the stack area to aslink.
11266 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11267 glue() in SDCCglue.c creates an area for it.
11269 2002-09-03 Borut Razem <borut.razem AT siol.net>
11270 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11271 sdcc/src/pic/glue.c:
11272 introduced atexit() handler for teporay files removal in case of
11273 errors, assertions, ...
11275 2002-08-29 Borut Razem <borut.razem AT siol.net>
11276 * sdcc/support/cpp2/auto-host_vc_in.h:
11277 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11278 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11279 Maybe there is a similar problem with BORLANDC? It should be checked!
11281 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11282 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11283 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11284 was not executed, and the compiler (cl) launched a warning:
11285 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11287 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11288 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11290 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11291 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11293 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11294 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11295 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11296 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11297 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11298 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11299 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11300 - added Release configuration in VS projects
11301 - review of compiler an linker options
11302 - VC .exe files are generated in bin_vc directory, not to interfere
11303 with binaries generated from other projects (cygwin, mingw, bcc ...)
11305 * sdcc/src/yacc.dsp: added
11307 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11308 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11309 and insert the version number definitions from .version
11311 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11313 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11314 added - genarate auto-host.h using auto-host_vc_in.h as template
11317 removed from CVS, generated automatically
11319 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11320 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11322 2002-08-11 Borut Razem <borut.razem AT siol.net>
11323 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11325 2002-08-10 Borut Razem <borut.razem AT siol.net>
11326 * src/SDCCmain.c (main):
11327 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11328 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11329 The consequence was that some temporary files were not removed.
11332 unification of code in functions tempfilename() and tempfile():
11333 function tempnam() is defined in Visual Studio 6.0 and .NET
11335 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11337 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11338 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11339 - removed compiler command line option /WX: Treats all warnings as errors
11340 - update a list of source files, included into the project
11342 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11343 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11344 changed project type to Generic Project so that can be correcly converted to VS.NET project
11346 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11348 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11350 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11352 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11353 added return 0 statements after assert() to make compiler happy
11355 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11356 added newline in the def file to keep MSC compiler satisfied
11358 * sdcc/src/z80/gen.c:
11359 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11360 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11361 - solved MSC error in function aopDump()
11363 * sdcc_vc.h: define PREFIX as "\\sdcc"
11365 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11366 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11369 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11370 - Rewrote the register banking algorithm.
11371 - Added pCode live-range analysis to registers (for now, only non-used and
11372 singly-used registers optimized away)
11374 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11376 * 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.

11401 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11403 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11405 2002-03-28 Johan Knol <johan AT balder>
11407 * src/SDCCval.c: fixed bug #532436
11409 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11411 Added "char *Processor" field to the port structure.
11414 Added -p option. Allows port dependent processor to be specified.
11417 Initialized the new field char *Processor field to NULL in all ports
11420 Compiler generated registers for interrupt context saving
11421 were not getting allocated.
11423 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11426 Fixed left shift. Will promote the left side of a left shift
11427 if a) left shifting more than size of operand or b) when assigned
11428 to something size > size of left side
11430 2002-03-14 Scott Dattalo <scott AT dattalo.com>

11434 analysis is restructured. ...
11436 * src/pic/device.h:
11439 * src/pic/device.c:
11440 Added. device.c is a PIC port hack to accomodate variations

11538 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11540 * sdcc/src/SDCCloop.c:
11541 Previous fix was not good. basic blocks that have "break" or "return" are
11542 not really partof a loop , but live ranges used in these blocks should
11543 be live thru the entire loop, so set partOfLoop but don't add them to
11546 2002-02-21 <johan AT FRIJA>
11548 * src/SDCCcse.c: fixed bug #514308
11550 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
