1308 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1310 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1311 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1313 One basic decision: e.g. src/clean.mk includes further files. In order
1314 to make this work there are two solutions:
1315 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1316 run configure on them. This way they can use
1317 'include $(srcdir)/port-clean.mk'
1318 - always include clean.mk by the Makefile at the same level. To avoid
1319 that `make clean` tries to include and build Makefile.dep the
1320 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1321 implemented, because now even `make uninstall` doesn't create
1322 Makefile.in. clean.mk could be eliminated by pasting it in
1325 * debugger/mcs51/Makefile.in: build own objects from library sources
1326 (SLIB, SDCC) in current directory
1328 * configure, configure.in: renamed --disable-device-lib-build in
1329 --disable-device-lib; added --enable-doc, the required tools are
1330 searched by configure; added result message; the toolchain for the
1331 belonging ports are now only built, if the port is enabled.
1333 * support/regression/*: all output is written in directory gen, because
1334 the fwk and ports directories don't livet in the build tree using vpath
1336 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1337 --disable-device-lib, added --enable-doc, added section VPATH
1339 * sim/ucsim/configure.in,
1340 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1341 z80 are enabled by default
1343 2006-04-24 Raphael Neider <rneider AT web.de>
1345 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1346 to config word, "pic14_"-prefixed some extern functions
1347 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1348 config word has been found
1349 * src/pic/device.h: added prototypes
1350 * src/pic/pcode.c: added "pic14_"-prefix where needed

1591 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
1593 * src/mcs51/gen.c (genCall): fixed bug 1457608
1595 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

1614 implemented patch 1120823 Thanks to Willy De la Court (normal
1615 interrupts need an interrupt number now if they are made critical),
1616 and enabled nesting of critical functions though not for gbz80
1617 (genCritical, genEndCritical): added functions
1618 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1619 * src/z80/mappings.i: added "ei" to all mappings

1628 2006-03-16 Raphael Neider <rneider AT web.de>
1630 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1631 the left operand is shorter than the result (c* = lit-c* + int),
1633 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1636 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1638 * src/.version: increased version number to 2.5.5
1639 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1640 linking is done manually in pic16 port's _linkEdit,
1641 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1642 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1643 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1644 allocate asmop as AOP_ACC,
1645 (aopForRemat): added parameter 'bool result' in function declaration,
1646 (pic16_aopGet): return AOP_ACC when accessing WREG,
1647 (pic16_popGetTempReg): minor modification,

1658 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1659 call to allocReg, not by manually allocating a new one,
1660 (pic16_assignRegisters): now before going through the register
1661 allocating functions mark all registers as free. This eliminates some
1662 side effects resulting from peephole parser done earlier in the backbone
1664 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1714 2006-03-06 Borut Razem <borut.razem AT siol.net>
1716 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1717 made the linker quiet
1719 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1721 * src/pic16/gen.c (genPcall): fixed bug #1443644
1722 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1723 which dumps before the function entry point a data byte which represents
1724 the number of the local variables used by the specified function, added
1725 'xinst' for initial support for Extended Instruction Support,
1726 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1727 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1728 port->fun_prefix anymore (may change later),
1729 (genFunction, genEndFunction): do not store/restore local registers for
1730 _main (this should take care the --main-return command line option in
1732 (genOr): removed some legacy pic-port instructions,
1733 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1734 performing operations with SFR's causes data to be written more than
1735 once to each SFR. Perhaps SFRs should be handled in special cases...
1736 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1738 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1739 into account for stack starting position,
1740 (struct OPTIONS pic16_optionsTable): added command line argument
1741 --extended or -y for Extended Instruction Support,
1742 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1743 (deassignLRs): *** perhaps the most important change, old 'for' code
1744 (commented out for reference), didn't account for some registers which
1745 were left marked 'not free' after a pointer operation. The change
1746 reduces register usage a lot in some cases
1748 2006-03-04 Borut Razem <borut.razem AT siol.net>
1750 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

4106 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4108 * device/lib/printf_large.c: removed inline assembly for portability and
4109 readability. Use printf_fast if speed or size are more important.
4110 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4111 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4113 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4115 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4116 prevent compiler warning
4118 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4120 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4121 moved to level 0 and declared as static. Also they are explicit
4122 placed in access bank. This was necessery because some times they
4123 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4124 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4125 optimizations. Currently only compare to unsigned char is implemented,
4126 * src/pic16/gen.c: added fReturnIdx array,
4127 * (struct resolvedIfx) is moved to gen.h and made public,
4128 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4129 * (aopForSym): added an optimization to directly store in stack of
4130 the operand of a SEND iCode,
4131 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4132 but as registers instead (AOP_REG) using the fReturnIdx array,
4133 * (pic16_freeAsmop): remove the freed register from the
4134 _G.sregsAlloc field,
4135 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4136 a compare of 'WREG',
4137 * (pic16_popGetTempRegCond): changed function prototype, now
4138 function takes also a bitVector argument v which holds the current
4139 set of registers that are allocated for stack access by aopForSym,
4140 registers allocated in aopForSym for accessing stack symbols are not
4141 any more part of the functions usedRegs field,
4142 * (genCall): some times aopOp is called for a stack variable to be
4143 send, aopForSym might perform the push, if this is true make sure
4144 that genCall doesn't push the variable twice by testing _G.resDirect,
4145 * (genFunction): changed testing for unspecified interrupt number
4146 from 256 to INTNO_UNSPEC,
4147 * modified selection scheme of frame pointer generation. Previously
4148 if function did use local registers a frame pointer was generated,
4149 now a frame pointer is generated only if function has arguments
4150 (that need PLUSW2 register access), or has stack arguments, or the
4151 compiler is not instructed to omit the frame pointer,
4152 * (genEndFunction): before restoring local registers that were saved
4153 in the function preamble, also restore the registers that *might*
4154 have been allocated for stack access,
4155 * (genRet): removed some old comments,
4156 * (genCmp, the active (RN's) version): added a call to the
4157 pic16_genCmp_special function to perform the compare with a more
4158 robust and optimized way,
4159 * (genInline): a feature has been added in inline code generation,
4160 which allows a wildcard variable substitution when writing inline
4161 assembly. Code is incomplete and experimental therefore undocumented,
4162 * (genCast): changed order of aopOp for result and right to allow
4163 aopForSym to directly load the result if possible,
4164 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4165 perform an optimized compare on some selected special occasions,
4166 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4167 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4168 generate an IVT any more,
4169 * src/pic16/main.c (pic16_optionsTable): added command line option
4171 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4172 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4174 * src/pic16/NOTES: Raphael Neider added in list of active developers
4175 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4176 jumptable_end to prevent bug #,
4177 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4178 inCond and outCond fields,
4179 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4180 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4181 turn off register spilling,
4182 * (packRegsForOneUse): synced with other ports' versions although it
4183 is not used currently,
4184 * (pic16_packRegisters): added an optimization while reading
4185 structure bitfields, some registers may be saved (malloc code is
4186 decreased by 80 bytes)
4188 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4190 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4191 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4192 this can be optimized more?
4194 2005-03-10 Raphael Neider <rneider AT web.de>
4196 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4197 genNearPointerGet): (hopefully) fixed access to bitfields via
4198 pointers (p->bitN = x; and x = p->bitN; failed)
4200 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4832 Adding support for replacing ljmps with sjmps in jumptables
4833 generated for switch statements. For now you need to set the
4834 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4835 Now 4 algorithms for mcs51 jumptable generation are used:
4836 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4837 addresses loaded pc-relative for up to 112 cases and stack-pushing
4838 target addresses loaded with offset from dptr for up to 256 cases.

4865 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4866 to call when a stack overflow occurs,
4867 * (malloc.h): added CVS Id tag,
4868 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4870 * added libc directory. The current version of LibC contains string
4871 functions, ctype functions and macros and some functions of the
4872 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4873 be extensively tested in the future. Standard disclaimer here.
4874 Library is not automatically build yet. But one can build it by
4875 invoking 'make' inside the libc directory.
4876 * added ADC library under libio. Preliminary version yet.

4882 temporary registers, its a buggy feature and will be removed,
4883 * (pic16_popGet): set register instance field in AOP_CRY,
4884 * (pic16_outBitC): fixed for results in size greater than 1,
4885 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4886 * (pic16_storeForReturn): optimized return of 0,
4887 * (genCmp): experimental code for new genCmp which uses PIC18's
4888 special compare&skip instructions. Initial tests fail some times
4889 with variables grater than 1 byte in size, so new code is disabled,
4890 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4892 * (genCast): began a fix to optimize the casting of a bit to another
4893 bit, now assigning a bitfield to another bitfield will fail, sorry,
4894 * src/pic16/main.c: disabled the use of lr-support feature,
4895 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4898 bits with offset (case PO_GPR_BIT),
4899 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4901 * (isBankInstruction): modified to return 0 for no banking instruction,
4902 and 1 for banking instruction,
4903 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4904 caused stop processing pCodes after a inline assembly block,
4905 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4906 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4907 registers when it shouldn't,
4908 * src/pic16/ralloc.c (allocReg): add preliminary support for
4909 supporting a limited set of temporary registers,
4911 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4913 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4914 genDataPointerSet): ensure assignments always copy in MSB to LSB
4916 (loadRegFromAop): recognize CLRH optimization,
4917 (genFunction): optimize RECEIVE iCodes in reentrant functions
4919 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7837 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
7838 'char' to 'int' can be omitted, if both operands are 'unsigned char';
7839 see feature request #877103
7840 * src/SDCCval.c: updated call of decorateType()
7841 (valBitwise): fixed bug #882876
7842 (valMinus): added promotion
7843 (valLogicAndOr): result is unsigned
7844 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
7845 * src/SDCCsymt.c (computeType),
7846 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
7847 must not cause an unsigned operation
7848 * src/pic/glue (pic14emitRegularMap),
7849 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
7851 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
7853 * src/pic/pcode.c (PCodeID): commented out left over debug code
7855 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>
7857 * support/valdiag/tests/overflow.c: added shift tests
7865 * src/pic/pcodepeep.c,
7866 * src/pic/pcoderegs.c,
7868 * src/pic/ralloc.h: applied patch from Slade Rich;
7869 added support for multiple code pages and multiple RAM banks on the
7870 PIC 14 port. The ASM files now no longer simply assume all the
7871 code / RAM are in the same page / bank. This means the linker can
7872 safely allocate code/RAM of separate ASM files to different pages/banks.
7873 * doc/sdccman.lyx: added Slade's tips
7874 * src/mcs51/peeph.def: fixed bug #880768

7883 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
7886 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
7887 strtof is not part of C89 and isn't included with Mac OS X.
7889 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7891 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

7916 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7918 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7919 loaded with the linker search paths (-L arguments) and the libraries
7920 to be linked with the current source (-l arguments). Changes
7921 currently will affect only the pic16 port.
7922 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7923 include path the port specific paths and port specific libraries,
7924 * gplink command now contains the $3 argument,
7925 * src/pic16/device.h,
7926 * src/pic16/device.c,: structure PIC_device is made public and
7927 renamed to PIC16_device, the same for variable Pics which is renamed

7940 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
7942 Documenting changes from previous commits.
7943 * configure.in (version 1.56),
7944 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7945 when generating output files to configure the pic16 library,
7946 but now I've commented it out, since gputils aren't installed in the
7947 SF compile farm, so library won't compile
7949 * device/lib/Makefile.in (version 1.56): initially I've added in
7950 target 'all' the prerequestive 'model-pic16' so it compiled the
7951 pic16 library, but now I've commented it out for the same reasons
7953 * added targets 'model-pic16' and 'objects-pic16' to compile the
7955 * added target 'port-specific-objects-pic16' to handle the
7956 generated libraries and copy them into the build/ directory
7957 * added target 'clean-intermediate-pic16' to clean intermediate
7958 files into pic16 directory
7959 * in target 'installdirs' added line to create directory pic16 in
7960 the installation path
7962 * device/include/Makefile.in (version 1.11): in target 'install'
7963 added lines to copy all header files to installation path,
7964 * in target 'installdirs' added line create directory for pic16
7965 headers in the installation path

7980 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7981 option so that it actually works. Made it specific to the z80, since
7982 the gbz80 doesn't have these kinds of I/O ports.
7984 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7986 * device/include/z180.h,

8008 Mainly changes to support compilation of the device libraries
8009 * src/pic16/device.c: stack is allocated via symbol and not
8010 via literal number. The symbol is placed in the corresponding
8011 position of the data ram
8012 * (pic16_dump_section): relocatable and absolute uninitialized
8013 data are now emitted in sorted order to reduce section naming,
8014 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8015 weren't marked as being in the access bank,
8017 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8019 Added portion of GNU PIC Library under the directory
8020 device/include/pic16 and device/lib/pic16. These files
8021 contain the declarations of SFRs for the PIC18Fxx2 devices.
8022 The directory is initialized via configure from toplevel.
8024 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
8026 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

8052 all over. Telling LaTeX to be less strict with word spacing
8053 to better keep the right margin. Changed some notes about
8054 maintainance of the ports in section 3.2.1 - is it OK like this?
8056 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8096 * src/pic16/peeph.def: all peepholes with movff are commented out,
8097 because there is a problem in the pcode peep optimizer,
8098 * src/pic16/ralloc.c: the register allocator can now reuse local

8250 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8252 PIC16 port related changes:
8253 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8254 added variable stackPos,
8256 * gen.c: genCall, assignResultValue: added support for
8257 pushing/retrieving function parameters to/from stack,
8258 genFunction,genEndFunction: setup stack frame for the
8260 genAddrOf: will be changed according to bug 863624
8262 * added files genutils.c and genutils.h which contain gen*
8263 debugged and optimised functions extracted from gen.c
8265 * glue.c: added variable 'externs' which holds extern symbols,
8266 pic16emitRegularMap: is modified to properly handle relocatable
8267 symbols under the new scheme,
8268 pic16createInterruptVect: is modified
8269 pic16printPublics: is modified to emit 'global' assembler directives,
8270 added pic16_printExterns to print extern symbols,
8271 pic16glue: initializes stack/frame pointer in the beginning of
8272 the assembly output. Temporary hack, will be corrected later,
8273 because gplink yet does not support stack and SDCC does not
8274 yet support a type of crt0.o object to create the final binary.
8276 * Removed many lines that contain 8051 legacy code.
8277 * The code is finally placed under a 'code' directive.
8278 * Added port specific options.
8280 * _process_pragma: simplified since now we do not need *special*
8281 include file to define SFR registers. But a separate header
8282 will be needed. This will be developed later.
8283 * _pic16_parseOptions: added, parses port specific options:
8284 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8285 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8286 --preplace-udata-with=
8288 * _pic16_setDefaultOptions: modified to initialize section names,
8289 but hack is temporarly out of order since it needs improvement.
8290 * _pic16_genAssemblerPreamble: configuration words are emitted by
8291 their address instead of their name. This part is incomplete and
8292 supports only the 18Fxx2 devices. Other devices will emit an error
8293 during assembly since they do not contain the same set of config
8295 * _pic16_genIVT: is modified,
8297 * pcode.c: added definitions for some hardware registers that are needed
8299 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8300 All PCI entries are updated. Now LFSR is supported.
8301 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8302 * added pic16_newpCodeOpLit2 to support instructions with
8303 two literal arguments
8304 * pic16_pCode2str: corrected code that emits assembler instructions
8305 with two literal operands and those that have an access bit modifier
8306 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8307 this fixes a bug which caused some labels to be lost, when an
8308 assembler directive was added, i.e. banksel,
8309 * pic16_FixRegisterBanking: improved logic that causes the insertion
8311 * InlineFunction: functions that are called once, are not any more
8312 inlined. This can be a port option in the future,
8314 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8316 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8317 hold the corresponding uninitialized symbols,
8318 * pic16_allocProcessorRegister: registers have explicit marked the
8320 * pic16_allocInternalRegister: registers are explicit marked as
8322 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8323 processing list, so bit registers were lost,
8326 * ralloc.h: added field 'accessBank' and original symbol operand
8327 in register definition,
8328 * removed the field isMapped from register definition,
8330 ** Several functions have been removed from various sources:

8342 * support/scripts/inc2h.pl: changed definition of BIT_AT
8343 to emit 'sbit at' instead of 'bit at'. This was a request.
8345 PIC16 port related preliminary changes:
8346 * gen.c: prefixed function popRegFromString with
8347 pic16_ and all references to it corrected
8348 * pcode.c: all pic16_pc_* hardware registers prefixed
8349 with underscore (_),
8350 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8351 * ralloc.c: newReg(): when register is REG_SFR then
8352 set address to rIdx,
8353 pic16_allocProcessorRegister(): marks register wasUsed=0
8354 pic16_writeUsedRegs(): added a call to assign processor
8355 registers via pic16_assignFixedRegisters
8357 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8359 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8360 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8361 variables in unused register banks. Also the SSEG is placed
8362 wherever there is enough space for it, and IDATA can be anywhere
8363 in internal RAM. For now compile using -Wl-Y[stack_size].
8364 The mem file is different for this option as well, since it
8365 makes no sense of talking about DSEG lenght.
8367 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8369 * src/SDCClrange.c: fixed bug 869095 that caused segfault

8614 * src/SDCCast.c (decorateType): disabled a transformation I added in
8615 revision 1.188 (access to fields of a structure at an absolute address);
8616 it breaks with bitfields, extern declarations, and gcse analysis.
8617 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8618 could be assigned through a pointer, so don't complain.

9362 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
9363 iCode properly now. Use getSize instead of nRegs since a & b
9364 aren't part of the nRegs tally.
9366 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
9368 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

9374 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9375 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9376 fetching of the pointer
9377 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9378 copied from genNearPointerSet()
9379 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9380 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9381 If they pop r0/r1 they must be called in the opposite order than aopOp().
9382 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9383 (resp. --stack-auto), prepared for --xstack

9394 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9396 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9397 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9398 type for bits was changed. It resulted in bit variables becoming
9399 global, which is not permitted in PIC 14 assembly output.
9401 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9403 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9416 A few small changes that speed up the peephole optimizer.
9420 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9422 Try to make the peephole optimizer smarter by maintaining
9423 an association between the assembly source code and the
9424 iCodes that originated them. Put this information to use
9425 with a new peephole rule condition "notVolatile" so that
9426 the rules can be aggressive yet still safe.
9431 * src/mcs51/peeph.def
9433 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9437 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9438 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9439 if the left or right operand symbols have the accuse flag set.
9441 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9443 Changed the type of the result of the ! (NOT) operator to char;
9444 previously it returned the same type as the source. This allows
9445 us to eliminate all the genFloatNot functions (all of its target
9446 implementations were very buggy) since !float can use the same
9449 * src/SDCCicode.c (ast2iCode): ! returns char
9450 * src/mcs51/gen.c (genNot, genNotFloat),
9451 * src/ds390/gen.c (genNot, genNotFloat),
9452 * src/z80/gen.c (genNot, genNotFloat),
9453 * src/pic/gen.c (genNot, genNotFloat),
9454 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

9458 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9459 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9460 during interrupts. Ensure WSAVE is located at a shared bank address.
9461 2. Fixed page selection in some places
9462 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9463 the registers name strings.
9464 4. Fixed "signed / unsigned compare" compiler warnings.
9465 5. The PIC port manages its own allocation of the general purpose
9466 registers, but makes no attempt to reuse them. As a result when
9467 compiling it soon runs out of general purpose registers. Some
9468 additional code was added to the files pcode.c and device.c to walk
9469 through the function call tree and rename the registers so that they
9479 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9480 genPlus() & genMinus() when the result is the same as left or right

9486 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9488 Made bitfield a distinct type from bit so that bitfields
9489 convert as per ANSI C and bits retain their traditional
9490 boolean style behaviour. Implemented bitfield support in
9498 * src/ds390/gen.c: bit v bitfield split
9499 * src/z80/gen.c: New support for bitfields
9500 * support/regression/tests/bitfields.c: reenabled z80,
9503 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9505 Rules 246.x, 247.x relate to bitfields, the others speed up
9506 access to xdata mapped I/O devices.
9508 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9510 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9512 Cleaned up genPackBits and genUnpackBits and added two helper
9513 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9514 for literal assignments in genPackBits (thanks to Frieder for
9520 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9522 Fixed bug #748310 (pointer to function type mishandled when the
9523 function name is omitted). Also fixed a SIGSEGV when a function
9524 attribute (reentrant, etc) is used on a non-function or on a
9525 function but misplaced before the parameter list.
9527 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9529 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

9552 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9554 Made the constant following the "interrupt" keyword optional. If
9555 omitted, the function will not automatically be given an entry
9556 in the interrupt vector table (similar to #pragma NOIV, but
9557 less syntacticly kludgy). The interrupt number is also now
9558 range checked. Also fixed a bug in the high order bit example
9565 * support/Util/SDCCerr.c
9566 * support/Util/SDCCerr.h
9569 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

9572 * src/SDCCicode.c (operandOperation): rewritten some ops
9573 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9574 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9576 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9577 be re-activated by defining REDUCE_LITERALS)
9578 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9579 unsigned, but are signed by default
9580 * src/SDCCval.c (constVal): rearranged
9581 * src/SDCCval.c (valMod): preliminary fix
9582 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10035 the regression tests I'm not brave enough to enable 245.b, 245.c
10036 * doc/sdccman.lyx: added latex preamble for hyperref package.
10037 Using pdflatex this will give you a hyperlinked pdf file with

10088 added if/endif conditional macros to remove options help
10089 messages from optionsTable when a port is not configured, added
10090 support for the PIc16 port in the ports table, when executing
10091 the compiler with no port specified on command line, a default
10092 port is selected with the new macro DEFAULT_PORT which is
10093 defined in port.h, in setDefaultOptions() linkOptions is removed
10094 from initialization assignment, since now it is a set,
10095 parseCmdLine uses setParseWithComma for linkOptions, in
10096 linkEdit() linkOptions are accessed with new function indexSet()
10097 which returns the i'th item of a set variable. See SDCCset.c, in
10098 linkEdit() when calling buildCmdLine(), added linkOptions as
10099 last argument. Now users can pass arguments to gplink via the
10100 -Wl option, main() uses pic16glue() to glue up pic16 programs

10113 * src/pic16/main.c: __config directives are commented out to stop
10114 gpasm complaining and test the linkage with gplink, _linkCmd and
10115 _asmCmd changed to be more gplink and gpasm friendly
10116 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10117 produced an error when parsed, peep rule 12 is added to utilize
10118 movff, but it is commented out since the pCode does not support
10119 yet a command with 2 address arguments
10121 2003-05-18 <johan AT balder>
10123 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11190 Makefile.aslink, Makefile.bcc, and Makefile.in.
11192 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11193 .adb instead of .cdb
11195 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11197 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11198 value from option --iram-size.
11200 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11202 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11205 2002-09-18 <wiml AT hhhh.org>
11207 * SDCClrange.h: exposed setFromRange() and setToRange()
11208 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11209 packRegsForAccUse() (bug 542397)
11210 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11211 multiple times and emitting the fetch operations more than once
11212 added aopGetUsesAcc() function to allow binary operators to
11213 fetch their operands in the correct order; made genMinus() emit
11214 compact code for X = LITERAL - Y
11216 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11217 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11218 sprintf() in line 1267.
11220 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11221 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11224 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11225 Changes to aslink (All the changes are marked with 'JCF'):
11227 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11230 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11231 area BSEG. Also moves, if possible, the DATA area down into the internal
11232 ram so more space is available.
11234 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11237 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11238 not bytes. Function summary() which creates a memory usage summary
11239 file with extension .mem. Reports of overlaping stack and small stack
11240 size. If the space for the stack is less than 16 bytes aslink trows a
11243 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11244 the 8051. Option 'y' for memory summary output file.
11246 Changes to sdcc (All the changes are marked with 'JCF'):
11248 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11250 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11251 overlaying area for it (uses RegBankUsed[4]).
11253 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11254 bank zero as used by default. By default aslink locates the stack
11255 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11256 the creation of the .mem file. Delegates the allocation of data area
11257 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11258 the begining of the stack area to aslink.
11260 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11261 glue() in SDCCglue.c creates an area for it.
11263 2002-09-03 Borut Razem <borut.razem AT siol.net>
11264 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11265 sdcc/src/pic/glue.c:
11266 introduced atexit() handler for teporay files removal in case of
11267 errors, assertions, ...
11269 2002-08-29 Borut Razem <borut.razem AT siol.net>
11270 * sdcc/support/cpp2/auto-host_vc_in.h:
11271 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11272 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11273 Maybe there is a similar problem with BORLANDC? It should be checked!
11275 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11276 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11277 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11278 was not executed, and the compiler (cl) launched a warning:
11279 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11281 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11282 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11284 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11285 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11287 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11288 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11289 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11290 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11291 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11292 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11293 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11294 - added Release configuration in VS projects
11295 - review of compiler an linker options
11296 - VC .exe files are generated in bin_vc directory, not to interfere
11297 with binaries generated from other projects (cygwin, mingw, bcc ...)
11299 * sdcc/src/yacc.dsp: added
11301 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11302 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11303 and insert the version number definitions from .version
11305 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11307 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11308 added - genarate auto-host.h using auto-host_vc_in.h as template
11311 removed from CVS, generated automatically
11313 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11314 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11316 2002-08-11 Borut Razem <borut.razem AT siol.net>
11317 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11319 2002-08-10 Borut Razem <borut.razem AT siol.net>
11320 * src/SDCCmain.c (main):
11321 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11322 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11323 The consequence was that some temporary files were not removed.
11326 unification of code in functions tempfilename() and tempfile():
11327 function tempnam() is defined in Visual Studio 6.0 and .NET
11329 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11331 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11332 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11333 - removed compiler command line option /WX: Treats all warnings as errors
11334 - update a list of source files, included into the project
11336 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11337 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11338 changed project type to Generic Project so that can be correcly converted to VS.NET project
11340 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11342 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11344 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11346 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11347 added return 0 statements after assert() to make compiler happy
11349 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11350 added newline in the def file to keep MSC compiler satisfied
11352 * sdcc/src/z80/gen.c:
11353 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11354 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11355 - solved MSC error in function aopDump()
11357 * sdcc_vc.h: define PREFIX as "\\sdcc"
11359 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11360 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11363 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11364 - Rewrote the register banking algorithm.
11365 - Added pCode live-range analysis to registers (for now, only non-used and
11366 singly-used registers optimized away)
11368 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11370 * 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.

11397 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11399 2002-03-28 Johan Knol <johan AT balder>
11401 * src/SDCCval.c: fixed bug #532436
11403 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11405 Added "char *Processor" field to the port structure.
11408 Added -p option. Allows port dependent processor to be specified.
11411 Initialized the new field char *Processor field to NULL in all ports
11414 Compiler generated registers for interrupt context saving
11415 were not getting allocated.
11417 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11420 Fixed left shift. Will promote the left side of a left shift
11421 if a) left shifting more than size of operand or b) when assigned
11422 to something size > size of left side
11424 2002-03-14 Scott Dattalo <scott AT dattalo.com>

11428 analysis is restructured. ...
11430 * src/pic/device.h:
11433 * src/pic/device.c:
11434 Added. device.c is a PIC port hack to accomodate variations
11437 2002-03-13 Michael Hope <michaelh AT vroom>
11439 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11441 2002-03-04 johanknol <johanknol AT manik>
11443 * /src/SDCCval.c: fixed
11445 const unsigned char arr[][2] = { { 0, 1 } };

11532 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11534 * sdcc/src/SDCCloop.c:
11535 Previous fix was not good. basic blocks that have "break" or "return" are
11536 not really partof a loop , but live ranges used in these blocks should
11537 be live thru the entire loop, so set partOfLoop but don't add them to
11540 2002-02-21 <johan AT FRIJA>
11542 * src/SDCCcse.c: fixed bug #514308
11544 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

11548 statement inside a loop, it was not being considered part of the loop.
11550 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
11552 2002-02-10 Karl Bongers <karl AT turbobit.com>
