1323 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1325 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1326 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1328 One basic decision: e.g. src/clean.mk includes further files. In order
1329 to make this work there are two solutions:
1330 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1331 run configure on them. This way they can use
1332 'include $(srcdir)/port-clean.mk'
1333 - always include clean.mk by the Makefile at the same level. To avoid
1334 that `make clean` tries to include and build Makefile.dep the
1335 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1336 implemented, because now even `make uninstall` doesn't create
1337 Makefile.in. clean.mk could be eliminated by pasting it in
1340 * debugger/mcs51/Makefile.in: build own objects from library sources
1341 (SLIB, SDCC) in current directory
1343 * configure, configure.in: renamed --disable-device-lib-build in
1344 --disable-device-lib; added --enable-doc, the required tools are
1345 searched by configure; added result message; the toolchain for the
1346 belonging ports are now only built, if the port is enabled.
1348 * support/regression/*: all output is written in directory gen, because
1349 the fwk and ports directories don't livet in the build tree using vpath
1351 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1352 --disable-device-lib, added --enable-doc, added section VPATH
1354 * sim/ucsim/configure.in,
1355 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1356 z80 are enabled by default

1606 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
1608 * src/mcs51/gen.c (genCall): fixed bug 1457608
1610 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

1629 implemented patch 1120823 Thanks to Willy De la Court (normal
1630 interrupts need an interrupt number now if they are made critical),
1631 and enabled nesting of critical functions though not for gbz80
1632 (genCritical, genEndCritical): added functions
1633 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1634 * src/z80/mappings.i: added "ei" to all mappings

1643 2006-03-16 Raphael Neider <rneider AT web.de>
1645 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1646 the left operand is shorter than the result (c* = lit-c* + int),
1648 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1651 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1653 * src/.version: increased version number to 2.5.5
1654 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1655 linking is done manually in pic16 port's _linkEdit,
1656 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1657 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1658 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1659 allocate asmop as AOP_ACC,
1660 (aopForRemat): added parameter 'bool result' in function declaration,
1661 (pic16_aopGet): return AOP_ACC when accessing WREG,
1662 (pic16_popGetTempReg): minor modification,

1673 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1674 call to allocReg, not by manually allocating a new one,
1675 (pic16_assignRegisters): now before going through the register
1676 allocating functions mark all registers as free. This eliminates some
1677 side effects resulting from peephole parser done earlier in the backbone
1679 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1729 2006-03-06 Borut Razem <borut.razem AT siol.net>
1731 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1732 made the linker quiet
1734 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1736 * src/pic16/gen.c (genPcall): fixed bug #1443644
1737 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1738 which dumps before the function entry point a data byte which represents
1739 the number of the local variables used by the specified function, added
1740 'xinst' for initial support for Extended Instruction Support,
1741 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1742 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1743 port->fun_prefix anymore (may change later),
1744 (genFunction, genEndFunction): do not store/restore local registers for
1745 _main (this should take care the --main-return command line option in
1747 (genOr): removed some legacy pic-port instructions,
1748 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1749 performing operations with SFR's causes data to be written more than
1750 once to each SFR. Perhaps SFRs should be handled in special cases...
1751 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1753 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1754 into account for stack starting position,
1755 (struct OPTIONS pic16_optionsTable): added command line argument
1756 --extended or -y for Extended Instruction Support,
1757 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1758 (deassignLRs): *** perhaps the most important change, old 'for' code
1759 (commented out for reference), didn't account for some registers which
1760 were left marked 'not free' after a pointer operation. The change
1761 reduces register usage a lot in some cases
1763 2006-03-04 Borut Razem <borut.razem AT siol.net>
1765 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

4036 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4037 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4038 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4039 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4040 always available in leading double underscore form. The C99 support is
4041 mostly missing, but it's a start.
4042 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4043 reserved identifier "__data".

4121 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4123 * device/lib/printf_large.c: removed inline assembly for portability and
4124 readability. Use printf_fast if speed or size are more important.
4125 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4126 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4128 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4130 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4131 prevent compiler warning
4133 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4135 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4136 moved to level 0 and declared as static. Also they are explicit
4137 placed in access bank. This was necessery because some times they
4138 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4139 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4140 optimizations. Currently only compare to unsigned char is implemented,
4141 * src/pic16/gen.c: added fReturnIdx array,
4142 * (struct resolvedIfx) is moved to gen.h and made public,
4143 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4144 * (aopForSym): added an optimization to directly store in stack of
4145 the operand of a SEND iCode,
4146 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4147 but as registers instead (AOP_REG) using the fReturnIdx array,
4148 * (pic16_freeAsmop): remove the freed register from the
4149 _G.sregsAlloc field,
4150 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4151 a compare of 'WREG',
4152 * (pic16_popGetTempRegCond): changed function prototype, now
4153 function takes also a bitVector argument v which holds the current
4154 set of registers that are allocated for stack access by aopForSym,
4155 registers allocated in aopForSym for accessing stack symbols are not
4156 any more part of the functions usedRegs field,
4157 * (genCall): some times aopOp is called for a stack variable to be
4158 send, aopForSym might perform the push, if this is true make sure
4159 that genCall doesn't push the variable twice by testing _G.resDirect,
4160 * (genFunction): changed testing for unspecified interrupt number
4161 from 256 to INTNO_UNSPEC,
4162 * modified selection scheme of frame pointer generation. Previously
4163 if function did use local registers a frame pointer was generated,
4164 now a frame pointer is generated only if function has arguments
4165 (that need PLUSW2 register access), or has stack arguments, or the
4166 compiler is not instructed to omit the frame pointer,
4167 * (genEndFunction): before restoring local registers that were saved
4168 in the function preamble, also restore the registers that *might*
4169 have been allocated for stack access,
4170 * (genRet): removed some old comments,
4171 * (genCmp, the active (RN's) version): added a call to the
4172 pic16_genCmp_special function to perform the compare with a more
4173 robust and optimized way,
4174 * (genInline): a feature has been added in inline code generation,
4175 which allows a wildcard variable substitution when writing inline
4176 assembly. Code is incomplete and experimental therefore undocumented,
4177 * (genCast): changed order of aopOp for result and right to allow
4178 aopForSym to directly load the result if possible,
4179 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4180 perform an optimized compare on some selected special occasions,
4181 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4182 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4183 generate an IVT any more,
4184 * src/pic16/main.c (pic16_optionsTable): added command line option
4186 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4187 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4189 * src/pic16/NOTES: Raphael Neider added in list of active developers
4190 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4191 jumptable_end to prevent bug #,
4192 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4193 inCond and outCond fields,
4194 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4195 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4196 turn off register spilling,
4197 * (packRegsForOneUse): synced with other ports' versions although it
4198 is not used currently,
4199 * (pic16_packRegisters): added an optimization while reading
4200 structure bitfields, some registers may be saved (malloc code is
4201 decreased by 80 bytes)
4203 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4205 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4206 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4207 this can be optimized more?
4209 2005-03-10 Raphael Neider <rneider AT web.de>
4211 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4212 genNearPointerGet): (hopefully) fixed access to bitfields via
4213 pointers (p->bitN = x; and x = p->bitN; failed)

4847 Adding support for replacing ljmps with sjmps in jumptables
4848 generated for switch statements. For now you need to set the
4849 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4850 Now 4 algorithms for mcs51 jumptable generation are used:
4851 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4852 addresses loaded pc-relative for up to 112 cases and stack-pushing
4853 target addresses loaded with offset from dptr for up to 256 cases.

4883 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4885 * added libc directory. The current version of LibC contains string
4886 functions, ctype functions and macros and some functions of the
4887 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4888 be extensively tested in the future. Standard disclaimer here.
4889 Library is not automatically build yet. But one can build it by
4890 invoking 'make' inside the libc directory.
4891 * added ADC library under libio. Preliminary version yet.

4901 * (pic16_storeForReturn): optimized return of 0,
4902 * (genCmp): experimental code for new genCmp which uses PIC18's
4903 special compare&skip instructions. Initial tests fail some times
4904 with variables grater than 1 byte in size, so new code is disabled,
4905 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4907 * (genCast): began a fix to optimize the casting of a bit to another
4908 bit, now assigning a bitfield to another bitfield will fail, sorry,
4909 * src/pic16/main.c: disabled the use of lr-support feature,
4910 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4913 bits with offset (case PO_GPR_BIT),
4914 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4916 * (isBankInstruction): modified to return 0 for no banking instruction,
4917 and 1 for banking instruction,
4918 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4919 caused stop processing pCodes after a inline assembly block,
4920 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4921 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4922 registers when it shouldn't,
4923 * src/pic16/ralloc.c (allocReg): add preliminary support for
4924 supporting a limited set of temporary registers,
4926 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4928 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

7837 * support/regression/generate-cases.py (main): Changed from inline
7840 * doc/Makefile (install): Changed to depth first to get rid of
7841 missing directory install warning.
7843 * as/Makefile (install-doc): Made work on Mac.
7845 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
7847 * src/SDCCast.c: added an additional type flow in decorateType() of
7848 opposite direction, see feature request #860006; it's enabled at runtime
7849 by setting the environment variable SDCC_NEWTYPEFLOW
7850 * src/SDCCast.h: changed prototype of decorateType()
7851 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
7852 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
7853 'char' to 'int' can be omitted, if both operands are 'unsigned char';
7854 see feature request #877103
7855 * src/SDCCval.c: updated call of decorateType()
7856 (valBitwise): fixed bug #882876
7857 (valMinus): added promotion
7858 (valLogicAndOr): result is unsigned
7859 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
7860 * src/SDCCsymt.c (computeType),
7861 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
7862 must not cause an unsigned operation
7863 * src/pic/glue (pic14emitRegularMap),
7864 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
7866 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>

7883 * src/pic/ralloc.h: applied patch from Slade Rich;
7884 added support for multiple code pages and multiple RAM banks on the
7885 PIC 14 port. The ASM files now no longer simply assume all the
7886 code / RAM are in the same page / bank. This means the linker can
7887 safely allocate code/RAM of separate ASM files to different pages/banks.
7888 * doc/sdccman.lyx: added Slade's tips
7889 * src/mcs51/peeph.def: fixed bug #880768

7898 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
7901 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
7902 strtof is not part of C89 and isn't included with Mac OS X.
7904 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7906 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

7931 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7933 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7934 loaded with the linker search paths (-L arguments) and the libraries
7935 to be linked with the current source (-l arguments). Changes
7936 currently will affect only the pic16 port.
7937 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7938 include path the port specific paths and port specific libraries,
7939 * gplink command now contains the $3 argument,
7940 * src/pic16/device.h,
7941 * src/pic16/device.c,: structure PIC_device is made public and
7942 renamed to PIC16_device, the same for variable Pics which is renamed

7955 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
7957 Documenting changes from previous commits.
7958 * configure.in (version 1.56),
7959 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7960 when generating output files to configure the pic16 library,
7961 but now I've commented it out, since gputils aren't installed in the
7962 SF compile farm, so library won't compile
7964 * device/lib/Makefile.in (version 1.56): initially I've added in
7965 target 'all' the prerequestive 'model-pic16' so it compiled the
7966 pic16 library, but now I've commented it out for the same reasons
7968 * added targets 'model-pic16' and 'objects-pic16' to compile the
7970 * added target 'port-specific-objects-pic16' to handle the
7971 generated libraries and copy them into the build/ directory
7972 * added target 'clean-intermediate-pic16' to clean intermediate
7973 files into pic16 directory
7974 * in target 'installdirs' added line to create directory pic16 in
7975 the installation path
7977 * device/include/Makefile.in (version 1.11): in target 'install'
7978 added lines to copy all header files to installation path,
7979 * in target 'installdirs' added line create directory for pic16
7980 headers in the installation path

7995 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7996 option so that it actually works. Made it specific to the z80, since
7997 the gbz80 doesn't have these kinds of I/O ports.
7999 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8001 * device/include/z180.h,

8023 Mainly changes to support compilation of the device libraries
8024 * src/pic16/device.c: stack is allocated via symbol and not
8025 via literal number. The symbol is placed in the corresponding
8026 position of the data ram
8027 * (pic16_dump_section): relocatable and absolute uninitialized
8028 data are now emitted in sorted order to reduce section naming,
8029 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8030 weren't marked as being in the access bank,
8032 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8034 Added portion of GNU PIC Library under the directory
8035 device/include/pic16 and device/lib/pic16. These files
8036 contain the declarations of SFRs for the PIC18Fxx2 devices.
8037 The directory is initialized via configure from toplevel.
8039 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

8067 all over. Telling LaTeX to be less strict with word spacing
8068 to better keep the right margin. Changed some notes about
8069 maintainance of the ports in section 3.2.1 - is it OK like this?
8071 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8109 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8111 * src/pic16/peeph.def: all peepholes with movff are commented out,
8112 because there is a problem in the pcode peep optimizer,
8113 * src/pic16/ralloc.c: the register allocator can now reuse local

8252 Bug reported from Jesus Calvino-Fraga
8254 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8256 * sdcc.spec: updated
8257 * device/include/Makefile.in: don't install CVS directories

8262 * src/ds390/gen.c (genRightShift): fixed bug #870788
8263 * src/SDCCast.c (decorateType): fixed bug #870781
8265 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8267 PIC16 port related changes:
8268 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8269 added variable stackPos,
8271 * gen.c: genCall, assignResultValue: added support for
8272 pushing/retrieving function parameters to/from stack,
8273 genFunction,genEndFunction: setup stack frame for the
8275 genAddrOf: will be changed according to bug 863624
8277 * added files genutils.c and genutils.h which contain gen*
8278 debugged and optimised functions extracted from gen.c
8280 * glue.c: added variable 'externs' which holds extern symbols,
8281 pic16emitRegularMap: is modified to properly handle relocatable
8282 symbols under the new scheme,
8283 pic16createInterruptVect: is modified
8284 pic16printPublics: is modified to emit 'global' assembler directives,
8285 added pic16_printExterns to print extern symbols,
8286 pic16glue: initializes stack/frame pointer in the beginning of
8287 the assembly output. Temporary hack, will be corrected later,
8288 because gplink yet does not support stack and SDCC does not
8289 yet support a type of crt0.o object to create the final binary.
8291 * Removed many lines that contain 8051 legacy code.
8292 * The code is finally placed under a 'code' directive.
8293 * Added port specific options.
8295 * _process_pragma: simplified since now we do not need *special*
8296 include file to define SFR registers. But a separate header
8297 will be needed. This will be developed later.
8298 * _pic16_parseOptions: added, parses port specific options:
8299 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8300 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8301 --preplace-udata-with=
8303 * _pic16_setDefaultOptions: modified to initialize section names,
8304 but hack is temporarly out of order since it needs improvement.
8305 * _pic16_genAssemblerPreamble: configuration words are emitted by
8306 their address instead of their name. This part is incomplete and
8307 supports only the 18Fxx2 devices. Other devices will emit an error
8308 during assembly since they do not contain the same set of config
8310 * _pic16_genIVT: is modified,
8312 * pcode.c: added definitions for some hardware registers that are needed
8314 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8315 All PCI entries are updated. Now LFSR is supported.
8316 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8317 * added pic16_newpCodeOpLit2 to support instructions with
8318 two literal arguments
8319 * pic16_pCode2str: corrected code that emits assembler instructions
8320 with two literal operands and those that have an access bit modifier
8321 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8322 this fixes a bug which caused some labels to be lost, when an
8323 assembler directive was added, i.e. banksel,
8324 * pic16_FixRegisterBanking: improved logic that causes the insertion
8326 * InlineFunction: functions that are called once, are not any more
8327 inlined. This can be a port option in the future,
8329 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8331 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8332 hold the corresponding uninitialized symbols,
8333 * pic16_allocProcessorRegister: registers have explicit marked the
8335 * pic16_allocInternalRegister: registers are explicit marked as
8337 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8338 processing list, so bit registers were lost,
8341 * ralloc.h: added field 'accessBank' and original symbol operand
8342 in register definition,
8343 * removed the field isMapped from register definition,
8345 ** Several functions have been removed from various sources:
8346 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8347 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8348 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8349 pic16_assignRelocatableRegisters
8351 ** others have been introduced:
8352 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8353 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8355 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8357 * support/scripts/inc2h.pl: changed definition of BIT_AT
8358 to emit 'sbit at' instead of 'bit at'. This was a request.
8360 PIC16 port related preliminary changes:
8361 * gen.c: prefixed function popRegFromString with
8362 pic16_ and all references to it corrected
8363 * pcode.c: all pic16_pc_* hardware registers prefixed
8364 with underscore (_),
8365 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8366 * ralloc.c: newReg(): when register is REG_SFR then
8367 set address to rIdx,
8368 pic16_allocProcessorRegister(): marks register wasUsed=0
8369 pic16_writeUsedRegs(): added a call to assign processor
8370 registers via pic16_assignFixedRegisters
8372 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8374 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8375 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8376 variables in unused register banks. Also the SSEG is placed
8377 wherever there is enough space for it, and IDATA can be anywhere
8378 in internal RAM. For now compile using -Wl-Y[stack_size].
8379 The mem file is different for this option as well, since it
8380 makes no sense of talking about DSEG lenght.
8382 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8384 * src/SDCClrange.c: fixed bug 869095 that caused segfault

8629 * src/SDCCast.c (decorateType): disabled a transformation I added in
8630 revision 1.188 (access to fields of a structure at an absolute address);
8631 it breaks with bitfields, extern declarations, and gcse analysis.
8632 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8633 could be assigned through a pointer, so don't complain.

9390 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9391 fetching of the pointer
9392 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9393 copied from genNearPointerSet()
9394 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9395 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

9409 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9411 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9412 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9413 type for bits was changed. It resulted in bit variables becoming
9414 global, which is not permitted in PIC 14 assembly output.
9416 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9418 * doc/sdccman.lyx: various additions and updates. Rearranged sections
9420 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9422 Z80 and MCS51 linkers complaint if a public symbol is defined

9431 A few small changes that speed up the peephole optimizer.
9435 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9437 Try to make the peephole optimizer smarter by maintaining
9438 an association between the assembly source code and the
9439 iCodes that originated them. Put this information to use
9440 with a new peephole rule condition "notVolatile" so that
9441 the rules can be aggressive yet still safe.
9446 * src/mcs51/peeph.def
9448 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9452 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9453 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9454 if the left or right operand symbols have the accuse flag set.
9456 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9458 Changed the type of the result of the ! (NOT) operator to char;
9459 previously it returned the same type as the source. This allows
9460 us to eliminate all the genFloatNot functions (all of its target
9461 implementations were very buggy) since !float can use the same
9464 * src/SDCCicode.c (ast2iCode): ! returns char
9465 * src/mcs51/gen.c (genNot, genNotFloat),
9466 * src/ds390/gen.c (genNot, genNotFloat),
9467 * src/z80/gen.c (genNot, genNotFloat),
9468 * src/pic/gen.c (genNot, genNotFloat),

9471 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
9473 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9474 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9475 during interrupts. Ensure WSAVE is located at a shared bank address.
9476 2. Fixed page selection in some places
9477 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9478 the registers name strings.
9479 4. Fixed "signed / unsigned compare" compiler warnings.
9480 5. The PIC port manages its own allocation of the general purpose
9481 registers, but makes no attempt to reuse them. As a result when
9482 compiling it soon runs out of general purpose registers. Some
9483 additional code was added to the files pcode.c and device.c to walk
9484 through the function call tree and rename the registers so that they
9494 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9495 genPlus() & genMinus() when the result is the same as left or right

9501 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9503 Made bitfield a distinct type from bit so that bitfields
9504 convert as per ANSI C and bits retain their traditional
9505 boolean style behaviour. Implemented bitfield support in
9513 * src/ds390/gen.c: bit v bitfield split
9514 * src/z80/gen.c: New support for bitfields
9515 * support/regression/tests/bitfields.c: reenabled z80,
9518 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9520 Rules 246.x, 247.x relate to bitfields, the others speed up
9521 access to xdata mapped I/O devices.
9523 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9525 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9527 Cleaned up genPackBits and genUnpackBits and added two helper
9528 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9529 for literal assignments in genPackBits (thanks to Frieder for
9535 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9537 Fixed bug #748310 (pointer to function type mishandled when the
9538 function name is omitted). Also fixed a SIGSEGV when a function
9539 attribute (reentrant, etc) is used on a non-function or on a
9540 function but misplaced before the parameter list.
9542 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9544 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

9567 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9569 Made the constant following the "interrupt" keyword optional. If
9570 omitted, the function will not automatically be given an entry
9571 in the interrupt vector table (similar to #pragma NOIV, but
9572 less syntacticly kludgy). The interrupt number is also now
9573 range checked. Also fixed a bug in the high order bit example

9587 * src/SDCCicode.c (operandOperation): rewritten some ops
9588 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9589 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9591 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9592 be re-activated by defining REDUCE_LITERALS)
9593 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9594 unsigned, but are signed by default
9595 * src/SDCCval.c (constVal): rearranged
9596 * src/SDCCval.c (valMod): preliminary fix
9597 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10050 the regression tests I'm not brave enough to enable 245.b, 245.c
10051 * doc/sdccman.lyx: added latex preamble for hyperref package.
10052 Using pdflatex this will give you a hyperlinked pdf file with

10094 it can be defined with CFLAGS when running configure
10095 * src/SDCCmain.c: fixed compiling + linking with object files
10097 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

10102 * src/SDCCmain.c: linkOptions is changed to set *,
10103 added if/endif conditional macros to remove options help
10104 messages from optionsTable when a port is not configured, added
10105 support for the PIc16 port in the ports table, when executing
10106 the compiler with no port specified on command line, a default
10107 port is selected with the new macro DEFAULT_PORT which is
10108 defined in port.h, in setDefaultOptions() linkOptions is removed
10109 from initialization assignment, since now it is a set,
10110 parseCmdLine uses setParseWithComma for linkOptions, in
10111 linkEdit() linkOptions are accessed with new function indexSet()
10112 which returns the i'th item of a set variable. See SDCCset.c, in
10113 linkEdit() when calling buildCmdLine(), added linkOptions as
10114 last argument. Now users can pass arguments to gplink via the
10115 -Wl option, main() uses pic16glue() to glue up pic16 programs
10116 * src/SDCCpeeph.c: various changes to support pic16
10117 * src/SDCCset.c: added function void *indexSet(set *, int) to

10127 * src/pic16/glue.c: commented out some error producing lines
10128 * src/pic16/main.c: __config directives are commented out to stop
10129 gpasm complaining and test the linkage with gplink, _linkCmd and
10130 _asmCmd changed to be more gplink and gpasm friendly
10131 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10132 produced an error when parsed, peep rule 12 is added to utilize
10133 movff, but it is commented out since the pCode does not support
10134 yet a command with 2 address arguments
10136 2003-05-18 <johan AT balder>
10138 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11196 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11197 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11199 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11201 * in /sdcc/as/mcs51/ changed these files in order to create an
11202 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11203 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11204 following files to include the previous two files: aslink.dsp,
11205 Makefile.aslink, Makefile.bcc, and Makefile.in.
11207 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11208 .adb instead of .cdb
11210 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11212 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11213 value from option --iram-size.
11215 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11217 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11220 2002-09-18 <wiml AT hhhh.org>
11222 * SDCClrange.h: exposed setFromRange() and setToRange()
11223 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11224 packRegsForAccUse() (bug 542397)
11225 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11226 multiple times and emitting the fetch operations more than once
11227 added aopGetUsesAcc() function to allow binary operators to
11228 fetch their operands in the correct order; made genMinus() emit
11229 compact code for X = LITERAL - Y
11231 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11232 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11233 sprintf() in line 1267.
11235 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11236 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11239 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11240 Changes to aslink (All the changes are marked with 'JCF'):
11242 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11245 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11246 area BSEG. Also moves, if possible, the DATA area down into the internal
11247 ram so more space is available.
11249 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11252 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11253 not bytes. Function summary() which creates a memory usage summary
11254 file with extension .mem. Reports of overlaping stack and small stack
11255 size. If the space for the stack is less than 16 bytes aslink trows a
11258 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11259 the 8051. Option 'y' for memory summary output file.
11261 Changes to sdcc (All the changes are marked with 'JCF'):
11263 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11265 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11266 overlaying area for it (uses RegBankUsed[4]).
11268 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11269 bank zero as used by default. By default aslink locates the stack
11270 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11271 the creation of the .mem file. Delegates the allocation of data area
11272 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11273 the begining of the stack area to aslink.
11275 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11276 glue() in SDCCglue.c creates an area for it.
11278 2002-09-03 Borut Razem <borut.razem AT siol.net>
11279 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11280 sdcc/src/pic/glue.c:
11281 introduced atexit() handler for teporay files removal in case of
11282 errors, assertions, ...
11284 2002-08-29 Borut Razem <borut.razem AT siol.net>
11285 * sdcc/support/cpp2/auto-host_vc_in.h:
11286 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11287 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11288 Maybe there is a similar problem with BORLANDC? It should be checked!
11290 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11291 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11292 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11293 was not executed, and the compiler (cl) launched a warning:
11294 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11296 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11297 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11299 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11300 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11302 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11303 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11304 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11305 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11306 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11307 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11308 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11309 - added Release configuration in VS projects
11310 - review of compiler an linker options
11311 - VC .exe files are generated in bin_vc directory, not to interfere
11312 with binaries generated from other projects (cygwin, mingw, bcc ...)
11314 * sdcc/src/yacc.dsp: added
11316 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11317 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11318 and insert the version number definitions from .version
11320 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11322 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11323 added - genarate auto-host.h using auto-host_vc_in.h as template
11326 removed from CVS, generated automatically
11328 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11329 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11331 2002-08-11 Borut Razem <borut.razem AT siol.net>
11332 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11334 2002-08-10 Borut Razem <borut.razem AT siol.net>
11335 * src/SDCCmain.c (main):
11336 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11337 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11338 The consequence was that some temporary files were not removed.
11341 unification of code in functions tempfilename() and tempfile():
11342 function tempnam() is defined in Visual Studio 6.0 and .NET
11344 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11346 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11347 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11348 - removed compiler command line option /WX: Treats all warnings as errors
11349 - update a list of source files, included into the project
11351 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11352 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11353 changed project type to Generic Project so that can be correcly converted to VS.NET project
11355 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11357 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11359 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11361 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11362 added return 0 statements after assert() to make compiler happy
11364 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11365 added newline in the def file to keep MSC compiler satisfied
11367 * sdcc/src/z80/gen.c:
11368 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11369 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11370 - solved MSC error in function aopDump()
11372 * sdcc_vc.h: define PREFIX as "\\sdcc"
11374 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11375 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
11377 2002-06-22 Scott Dattalo <scott AT dattalo.com>
11378 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11379 - Rewrote the register banking algorithm.
11380 - Added pCode live-range analysis to registers (for now, only non-used and
11381 singly-used registers optimized away)
11383 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11385 * 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.

11408 * src/z80/main.c: Added force callee saves for jaune.
11410 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11412 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11414 2002-03-28 Johan Knol <johan AT balder>
11416 * src/SDCCval.c: fixed bug #532436
11418 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11420 Added "char *Processor" field to the port structure.
11423 Added -p option. Allows port dependent processor to be specified.
11426 Initialized the new field char *Processor field to NULL in all ports
11429 Compiler generated registers for interrupt context saving
11430 were not getting allocated.
11432 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11435 Fixed left shift. Will promote the left side of a left shift
11436 if a) left shifting more than size of operand or b) when assigned
11437 to something size > size of left side
11439 2002-03-14 Scott Dattalo <scott AT dattalo.com>

11443 analysis is restructured. ...
11445 * src/pic/device.h:
11448 * src/pic/device.c:
11449 Added. device.c is a PIC port hack to accomodate variations
11452 2002-03-13 Michael Hope <michaelh AT vroom>
11454 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11456 2002-03-04 johanknol <johanknol AT manik>
11458 * /src/SDCCval.c: fixed
11460 const unsigned char arr[][2] = { { 0, 1 } };

11547 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11549 * sdcc/src/SDCCloop.c:
11550 Previous fix was not good. basic blocks that have "break" or "return" are
11551 not really partof a loop , but live ranges used in these blocks should
11552 be live thru the entire loop, so set partOfLoop but don't add them to
11555 2002-02-21 <johan AT FRIJA>
11557 * src/SDCCcse.c: fixed bug #514308
11559 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
