1318 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1320 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1321 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1323 One basic decision: e.g. src/clean.mk includes further files. In order
1324 to make this work there are two solutions:
1325 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1326 run configure on them. This way they can use
1327 'include $(srcdir)/port-clean.mk'
1328 - always include clean.mk by the Makefile at the same level. To avoid
1329 that `make clean` tries to include and build Makefile.dep the
1330 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1331 implemented, because now even `make uninstall` doesn't create
1332 Makefile.in. clean.mk could be eliminated by pasting it in
1335 * debugger/mcs51/Makefile.in: build own objects from library sources
1336 (SLIB, SDCC) in current directory
1338 * configure, configure.in: renamed --disable-device-lib-build in
1339 --disable-device-lib; added --enable-doc, the required tools are
1340 searched by configure; added result message; the toolchain for the
1341 belonging ports are now only built, if the port is enabled.
1343 * support/regression/*: all output is written in directory gen, because
1344 the fwk and ports directories don't livet in the build tree using vpath
1346 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1347 --disable-device-lib, added --enable-doc, added section VPATH
1349 * sim/ucsim/configure.in,
1350 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1351 z80 are enabled by default
1353 2006-04-24 Raphael Neider <rneider AT web.de>

1601 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
1603 * src/mcs51/gen.c (genCall): fixed bug 1457608
1605 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

1624 implemented patch 1120823 Thanks to Willy De la Court (normal
1625 interrupts need an interrupt number now if they are made critical),
1626 and enabled nesting of critical functions though not for gbz80
1627 (genCritical, genEndCritical): added functions
1628 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1629 * src/z80/mappings.i: added "ei" to all mappings

1638 2006-03-16 Raphael Neider <rneider AT web.de>
1640 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1641 the left operand is shorter than the result (c* = lit-c* + int),
1643 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1646 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1648 * src/.version: increased version number to 2.5.5
1649 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1650 linking is done manually in pic16 port's _linkEdit,
1651 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1652 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1653 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1654 allocate asmop as AOP_ACC,
1655 (aopForRemat): added parameter 'bool result' in function declaration,
1656 (pic16_aopGet): return AOP_ACC when accessing WREG,
1657 (pic16_popGetTempReg): minor modification,

1668 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1669 call to allocReg, not by manually allocating a new one,
1670 (pic16_assignRegisters): now before going through the register
1671 allocating functions mark all registers as free. This eliminates some
1672 side effects resulting from peephole parser done earlier in the backbone
1674 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1724 2006-03-06 Borut Razem <borut.razem AT siol.net>
1726 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1727 made the linker quiet
1729 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1731 * src/pic16/gen.c (genPcall): fixed bug #1443644
1732 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1733 which dumps before the function entry point a data byte which represents
1734 the number of the local variables used by the specified function, added
1735 'xinst' for initial support for Extended Instruction Support,
1736 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1737 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1738 port->fun_prefix anymore (may change later),
1739 (genFunction, genEndFunction): do not store/restore local registers for
1740 _main (this should take care the --main-return command line option in
1742 (genOr): removed some legacy pic-port instructions,
1743 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1744 performing operations with SFR's causes data to be written more than
1745 once to each SFR. Perhaps SFRs should be handled in special cases...
1746 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1748 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1749 into account for stack starting position,
1750 (struct OPTIONS pic16_optionsTable): added command line argument
1751 --extended or -y for Extended Instruction Support,
1752 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1753 (deassignLRs): *** perhaps the most important change, old 'for' code
1754 (commented out for reference), didn't account for some registers which
1755 were left marked 'not free' after a pointer operation. The change
1756 reduces register usage a lot in some cases
1758 2006-03-04 Borut Razem <borut.razem AT siol.net>
1760 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

4032 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4033 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4034 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4035 always available in leading double underscore form. The C99 support is

4116 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4118 * device/lib/printf_large.c: removed inline assembly for portability and
4119 readability. Use printf_fast if speed or size are more important.
4120 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4121 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4123 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4125 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4126 prevent compiler warning
4128 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4130 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4131 moved to level 0 and declared as static. Also they are explicit
4132 placed in access bank. This was necessery because some times they
4133 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4134 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4135 optimizations. Currently only compare to unsigned char is implemented,
4136 * src/pic16/gen.c: added fReturnIdx array,
4137 * (struct resolvedIfx) is moved to gen.h and made public,
4138 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4139 * (aopForSym): added an optimization to directly store in stack of
4140 the operand of a SEND iCode,
4141 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4142 but as registers instead (AOP_REG) using the fReturnIdx array,
4143 * (pic16_freeAsmop): remove the freed register from the
4144 _G.sregsAlloc field,
4145 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4146 a compare of 'WREG',
4147 * (pic16_popGetTempRegCond): changed function prototype, now
4148 function takes also a bitVector argument v which holds the current
4149 set of registers that are allocated for stack access by aopForSym,
4150 registers allocated in aopForSym for accessing stack symbols are not
4151 any more part of the functions usedRegs field,
4152 * (genCall): some times aopOp is called for a stack variable to be
4153 send, aopForSym might perform the push, if this is true make sure
4154 that genCall doesn't push the variable twice by testing _G.resDirect,
4155 * (genFunction): changed testing for unspecified interrupt number
4156 from 256 to INTNO_UNSPEC,
4157 * modified selection scheme of frame pointer generation. Previously
4158 if function did use local registers a frame pointer was generated,
4159 now a frame pointer is generated only if function has arguments
4160 (that need PLUSW2 register access), or has stack arguments, or the
4161 compiler is not instructed to omit the frame pointer,
4162 * (genEndFunction): before restoring local registers that were saved
4163 in the function preamble, also restore the registers that *might*
4164 have been allocated for stack access,
4165 * (genRet): removed some old comments,
4166 * (genCmp, the active (RN's) version): added a call to the
4167 pic16_genCmp_special function to perform the compare with a more
4168 robust and optimized way,
4169 * (genInline): a feature has been added in inline code generation,
4170 which allows a wildcard variable substitution when writing inline
4171 assembly. Code is incomplete and experimental therefore undocumented,
4172 * (genCast): changed order of aopOp for result and right to allow
4173 aopForSym to directly load the result if possible,
4174 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4175 perform an optimized compare on some selected special occasions,
4176 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4177 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4178 generate an IVT any more,
4179 * src/pic16/main.c (pic16_optionsTable): added command line option
4181 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4182 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4184 * src/pic16/NOTES: Raphael Neider added in list of active developers
4185 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4186 jumptable_end to prevent bug #,
4187 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4188 inCond and outCond fields,
4189 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4190 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4191 turn off register spilling,
4192 * (packRegsForOneUse): synced with other ports' versions although it
4193 is not used currently,
4194 * (pic16_packRegisters): added an optimization while reading
4195 structure bitfields, some registers may be saved (malloc code is
4196 decreased by 80 bytes)
4198 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4200 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4201 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4202 this can be optimized more?
4204 2005-03-10 Raphael Neider <rneider AT web.de>
4206 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4207 genNearPointerGet): (hopefully) fixed access to bitfields via
4208 pointers (p->bitN = x; and x = p->bitN; failed)
4210 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4842 Adding support for replacing ljmps with sjmps in jumptables
4843 generated for switch statements. For now you need to set the
4844 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4845 Now 4 algorithms for mcs51 jumptable generation are used:
4846 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4847 addresses loaded pc-relative for up to 112 cases and stack-pushing
4848 target addresses loaded with offset from dptr for up to 256 cases.

4878 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4880 * added libc directory. The current version of LibC contains string
4881 functions, ctype functions and macros and some functions of the
4882 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4883 be extensively tested in the future. Standard disclaimer here.
4884 Library is not automatically build yet. But one can build it by
4885 invoking 'make' inside the libc directory.
4886 * added ADC library under libio. Preliminary version yet.

4895 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4896 * (pic16_storeForReturn): optimized return of 0,
4897 * (genCmp): experimental code for new genCmp which uses PIC18's
4898 special compare&skip instructions. Initial tests fail some times
4899 with variables grater than 1 byte in size, so new code is disabled,
4900 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4902 * (genCast): began a fix to optimize the casting of a bit to another
4903 bit, now assigning a bitfield to another bitfield will fail, sorry,
4904 * src/pic16/main.c: disabled the use of lr-support feature,
4905 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4908 bits with offset (case PO_GPR_BIT),
4909 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4911 * (isBankInstruction): modified to return 0 for no banking instruction,
4912 and 1 for banking instruction,
4913 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4914 caused stop processing pCodes after a inline assembly block,
4915 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4916 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4917 registers when it shouldn't,
4918 * src/pic16/ralloc.c (allocReg): add preliminary support for
4919 supporting a limited set of temporary registers,
4921 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4923 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4924 genDataPointerSet): ensure assignments always copy in MSB to LSB
4926 (loadRegFromAop): recognize CLRH optimization,
4927 (genFunction): optimize RECEIVE iCodes in reentrant functions
4929 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7845 * src/SDCCast.h: changed prototype of decorateType()
7846 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
7847 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
7848 'char' to 'int' can be omitted, if both operands are 'unsigned char';
7849 see feature request #877103
7850 * src/SDCCval.c: updated call of decorateType()
7851 (valBitwise): fixed bug #882876
7852 (valMinus): added promotion
7853 (valLogicAndOr): result is unsigned
7854 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
7855 * src/SDCCsymt.c (computeType),
7856 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
7857 must not cause an unsigned operation
7858 * src/pic/glue (pic14emitRegularMap),
7859 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
7861 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>

7878 * src/pic/ralloc.h: applied patch from Slade Rich;
7879 added support for multiple code pages and multiple RAM banks on the
7880 PIC 14 port. The ASM files now no longer simply assume all the
7881 code / RAM are in the same page / bank. This means the linker can
7882 safely allocate code/RAM of separate ASM files to different pages/banks.
7883 * doc/sdccman.lyx: added Slade's tips
7884 * src/mcs51/peeph.def: fixed bug #880768

7893 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
7896 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
7897 strtof is not part of C89 and isn't included with Mac OS X.
7899 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7901 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

7926 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7928 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7929 loaded with the linker search paths (-L arguments) and the libraries
7930 to be linked with the current source (-l arguments). Changes
7931 currently will affect only the pic16 port.
7932 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7933 include path the port specific paths and port specific libraries,
7934 * gplink command now contains the $3 argument,
7935 * src/pic16/device.h,
7936 * src/pic16/device.c,: structure PIC_device is made public and
7937 renamed to PIC16_device, the same for variable Pics which is renamed

7950 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
7952 Documenting changes from previous commits.
7953 * configure.in (version 1.56),
7954 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7955 when generating output files to configure the pic16 library,
7956 but now I've commented it out, since gputils aren't installed in the
7957 SF compile farm, so library won't compile
7959 * device/lib/Makefile.in (version 1.56): initially I've added in
7960 target 'all' the prerequestive 'model-pic16' so it compiled the
7961 pic16 library, but now I've commented it out for the same reasons
7963 * added targets 'model-pic16' and 'objects-pic16' to compile the
7965 * added target 'port-specific-objects-pic16' to handle the
7966 generated libraries and copy them into the build/ directory
7967 * added target 'clean-intermediate-pic16' to clean intermediate
7968 files into pic16 directory
7969 * in target 'installdirs' added line to create directory pic16 in
7970 the installation path
7972 * device/include/Makefile.in (version 1.11): in target 'install'
7973 added lines to copy all header files to installation path,
7974 * in target 'installdirs' added line create directory for pic16
7975 headers in the installation path

7990 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7991 option so that it actually works. Made it specific to the z80, since
7992 the gbz80 doesn't have these kinds of I/O ports.
7994 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7996 * device/include/z180.h,

8018 Mainly changes to support compilation of the device libraries
8019 * src/pic16/device.c: stack is allocated via symbol and not
8020 via literal number. The symbol is placed in the corresponding
8021 position of the data ram
8022 * (pic16_dump_section): relocatable and absolute uninitialized
8023 data are now emitted in sorted order to reduce section naming,
8024 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8025 weren't marked as being in the access bank,
8027 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8029 Added portion of GNU PIC Library under the directory
8030 device/include/pic16 and device/lib/pic16. These files
8031 contain the declarations of SFRs for the PIC18Fxx2 devices.
8032 The directory is initialized via configure from toplevel.
8034 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
8036 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

8048 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
8050 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
8051 in simpler and even better code

8062 all over. Telling LaTeX to be less strict with word spacing
8063 to better keep the right margin. Changed some notes about
8064 maintainance of the ports in section 3.2.1 - is it OK like this?
8066 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8104 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8106 * src/pic16/peeph.def: all peepholes with movff are commented out,
8107 because there is a problem in the pcode peep optimizer,
8108 * src/pic16/ralloc.c: the register allocator can now reuse local

8260 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8262 PIC16 port related changes:
8263 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8264 added variable stackPos,
8266 * gen.c: genCall, assignResultValue: added support for
8267 pushing/retrieving function parameters to/from stack,
8268 genFunction,genEndFunction: setup stack frame for the
8270 genAddrOf: will be changed according to bug 863624
8272 * added files genutils.c and genutils.h which contain gen*
8273 debugged and optimised functions extracted from gen.c
8275 * glue.c: added variable 'externs' which holds extern symbols,
8276 pic16emitRegularMap: is modified to properly handle relocatable
8277 symbols under the new scheme,
8278 pic16createInterruptVect: is modified
8279 pic16printPublics: is modified to emit 'global' assembler directives,
8280 added pic16_printExterns to print extern symbols,
8281 pic16glue: initializes stack/frame pointer in the beginning of
8282 the assembly output. Temporary hack, will be corrected later,
8283 because gplink yet does not support stack and SDCC does not
8284 yet support a type of crt0.o object to create the final binary.
8286 * Removed many lines that contain 8051 legacy code.
8287 * The code is finally placed under a 'code' directive.
8288 * Added port specific options.
8290 * _process_pragma: simplified since now we do not need *special*
8291 include file to define SFR registers. But a separate header
8292 will be needed. This will be developed later.
8293 * _pic16_parseOptions: added, parses port specific options:
8294 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8295 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8296 --preplace-udata-with=
8298 * _pic16_setDefaultOptions: modified to initialize section names,
8299 but hack is temporarly out of order since it needs improvement.
8300 * _pic16_genAssemblerPreamble: configuration words are emitted by
8301 their address instead of their name. This part is incomplete and
8302 supports only the 18Fxx2 devices. Other devices will emit an error
8303 during assembly since they do not contain the same set of config
8305 * _pic16_genIVT: is modified,
8307 * pcode.c: added definitions for some hardware registers that are needed
8309 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8310 All PCI entries are updated. Now LFSR is supported.
8311 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8312 * added pic16_newpCodeOpLit2 to support instructions with
8313 two literal arguments
8314 * pic16_pCode2str: corrected code that emits assembler instructions
8315 with two literal operands and those that have an access bit modifier
8316 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8317 this fixes a bug which caused some labels to be lost, when an
8318 assembler directive was added, i.e. banksel,
8319 * pic16_FixRegisterBanking: improved logic that causes the insertion
8321 * InlineFunction: functions that are called once, are not any more
8322 inlined. This can be a port option in the future,
8324 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8326 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8327 hold the corresponding uninitialized symbols,
8328 * pic16_allocProcessorRegister: registers have explicit marked the
8330 * pic16_allocInternalRegister: registers are explicit marked as
8332 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8333 processing list, so bit registers were lost,
8336 * ralloc.h: added field 'accessBank' and original symbol operand
8337 in register definition,
8338 * removed the field isMapped from register definition,
8340 ** Several functions have been removed from various sources:

8350 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8352 * support/scripts/inc2h.pl: changed definition of BIT_AT
8353 to emit 'sbit at' instead of 'bit at'. This was a request.
8355 PIC16 port related preliminary changes:
8356 * gen.c: prefixed function popRegFromString with
8357 pic16_ and all references to it corrected
8358 * pcode.c: all pic16_pc_* hardware registers prefixed
8359 with underscore (_),
8360 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8361 * ralloc.c: newReg(): when register is REG_SFR then
8362 set address to rIdx,
8363 pic16_allocProcessorRegister(): marks register wasUsed=0
8364 pic16_writeUsedRegs(): added a call to assign processor
8365 registers via pic16_assignFixedRegisters
8367 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8369 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8370 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8371 variables in unused register banks. Also the SSEG is placed
8372 wherever there is enough space for it, and IDATA can be anywhere
8373 in internal RAM. For now compile using -Wl-Y[stack_size].
8374 The mem file is different for this option as well, since it
8375 makes no sense of talking about DSEG lenght.
8377 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8379 * src/SDCClrange.c: fixed bug 869095 that caused segfault

8626 it breaks with bitfields, extern declarations, and gcse analysis.
8627 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8628 could be assigned through a pointer, so don't complain.

9372 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
9373 iCode properly now. Use getSize instead of nRegs since a & b
9374 aren't part of the nRegs tally.
9376 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
9378 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

9385 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9386 fetching of the pointer
9387 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9388 copied from genNearPointerSet()
9389 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9390 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9391 If they pop r0/r1 they must be called in the opposite order than aopOp().
9392 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9393 (resp. --stack-auto), prepared for --xstack

9404 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9406 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9407 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9408 type for bits was changed. It resulted in bit variables becoming
9409 global, which is not permitted in PIC 14 assembly output.
9411 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9413 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9426 A few small changes that speed up the peephole optimizer.
9430 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9432 Try to make the peephole optimizer smarter by maintaining
9433 an association between the assembly source code and the
9434 iCodes that originated them. Put this information to use
9435 with a new peephole rule condition "notVolatile" so that
9436 the rules can be aggressive yet still safe.
9441 * src/mcs51/peeph.def
9443 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9447 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9448 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9449 if the left or right operand symbols have the accuse flag set.
9451 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9453 Changed the type of the result of the ! (NOT) operator to char;
9454 previously it returned the same type as the source. This allows
9455 us to eliminate all the genFloatNot functions (all of its target
9456 implementations were very buggy) since !float can use the same
9459 * src/SDCCicode.c (ast2iCode): ! returns char

9461 * src/ds390/gen.c (genNot, genNotFloat),
9462 * src/z80/gen.c (genNot, genNotFloat),
9463 * src/pic/gen.c (genNot, genNotFloat),

9468 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9469 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9470 during interrupts. Ensure WSAVE is located at a shared bank address.
9471 2. Fixed page selection in some places
9472 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9473 the registers name strings.
9474 4. Fixed "signed / unsigned compare" compiler warnings.
9475 5. The PIC port manages its own allocation of the general purpose
9476 registers, but makes no attempt to reuse them. As a result when
9477 compiling it soon runs out of general purpose registers. Some
9478 additional code was added to the files pcode.c and device.c to walk
9479 through the function call tree and rename the registers so that they
9489 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9490 genPlus() & genMinus() when the result is the same as left or right

9496 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9498 Made bitfield a distinct type from bit so that bitfields
9499 convert as per ANSI C and bits retain their traditional
9500 boolean style behaviour. Implemented bitfield support in
9508 * src/ds390/gen.c: bit v bitfield split
9509 * src/z80/gen.c: New support for bitfields
9510 * support/regression/tests/bitfields.c: reenabled z80,
9513 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9515 Rules 246.x, 247.x relate to bitfields, the others speed up
9516 access to xdata mapped I/O devices.
9518 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9520 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9522 Cleaned up genPackBits and genUnpackBits and added two helper
9523 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9524 for literal assignments in genPackBits (thanks to Frieder for
9530 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9532 Fixed bug #748310 (pointer to function type mishandled when the
9533 function name is omitted). Also fixed a SIGSEGV when a function
9534 attribute (reentrant, etc) is used on a non-function or on a
9535 function but misplaced before the parameter list.
9537 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9539 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

9562 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9564 Made the constant following the "interrupt" keyword optional. If
9565 omitted, the function will not automatically be given an entry
9566 in the interrupt vector table (similar to #pragma NOIV, but
9567 less syntacticly kludgy). The interrupt number is also now
9568 range checked. Also fixed a bug in the high order bit example
9575 * support/Util/SDCCerr.c
9576 * support/Util/SDCCerr.h
9579 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

9582 * src/SDCCicode.c (operandOperation): rewritten some ops
9583 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9584 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9586 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9587 be re-activated by defining REDUCE_LITERALS)
9588 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9589 unsigned, but are signed by default
9590 * src/SDCCval.c (constVal): rearranged
9591 * src/SDCCval.c (valMod): preliminary fix
9592 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10098 added if/endif conditional macros to remove options help
10099 messages from optionsTable when a port is not configured, added
10100 support for the PIc16 port in the ports table, when executing
10101 the compiler with no port specified on command line, a default
10102 port is selected with the new macro DEFAULT_PORT which is
10103 defined in port.h, in setDefaultOptions() linkOptions is removed
10104 from initialization assignment, since now it is a set,
10105 parseCmdLine uses setParseWithComma for linkOptions, in
10106 linkEdit() linkOptions are accessed with new function indexSet()
10107 which returns the i'th item of a set variable. See SDCCset.c, in
10108 linkEdit() when calling buildCmdLine(), added linkOptions as
10109 last argument. Now users can pass arguments to gplink via the
10110 -Wl option, main() uses pic16glue() to glue up pic16 programs

10123 * src/pic16/main.c: __config directives are commented out to stop
10124 gpasm complaining and test the linkage with gplink, _linkCmd and
10125 _asmCmd changed to be more gplink and gpasm friendly
10126 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10127 produced an error when parsed, peep rule 12 is added to utilize
10128 movff, but it is commented out since the pCode does not support
10129 yet a command with 2 address arguments
10131 2003-05-18 <johan AT balder>
10133 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11198 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11199 following files to include the previous two files: aslink.dsp,
11200 Makefile.aslink, Makefile.bcc, and Makefile.in.
11202 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11203 .adb instead of .cdb
11205 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11207 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11208 value from option --iram-size.
11210 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11212 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11215 2002-09-18 <wiml AT hhhh.org>
11217 * SDCClrange.h: exposed setFromRange() and setToRange()
11218 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11219 packRegsForAccUse() (bug 542397)
11220 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11221 multiple times and emitting the fetch operations more than once
11222 added aopGetUsesAcc() function to allow binary operators to
11223 fetch their operands in the correct order; made genMinus() emit
11224 compact code for X = LITERAL - Y
11226 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11227 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11228 sprintf() in line 1267.
11230 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11231 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11234 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11235 Changes to aslink (All the changes are marked with 'JCF'):
11237 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11240 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11241 area BSEG. Also moves, if possible, the DATA area down into the internal
11242 ram so more space is available.
11244 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11247 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11248 not bytes. Function summary() which creates a memory usage summary
11249 file with extension .mem. Reports of overlaping stack and small stack
11250 size. If the space for the stack is less than 16 bytes aslink trows a
11253 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11254 the 8051. Option 'y' for memory summary output file.
11256 Changes to sdcc (All the changes are marked with 'JCF'):
11258 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11260 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11261 overlaying area for it (uses RegBankUsed[4]).
11263 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11264 bank zero as used by default. By default aslink locates the stack
11265 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11266 the creation of the .mem file. Delegates the allocation of data area
11267 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11268 the begining of the stack area to aslink.
11270 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11271 glue() in SDCCglue.c creates an area for it.
11273 2002-09-03 Borut Razem <borut.razem AT siol.net>
11274 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11275 sdcc/src/pic/glue.c:
11276 introduced atexit() handler for teporay files removal in case of
11277 errors, assertions, ...
11279 2002-08-29 Borut Razem <borut.razem AT siol.net>
11280 * sdcc/support/cpp2/auto-host_vc_in.h:
11281 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11282 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11283 Maybe there is a similar problem with BORLANDC? It should be checked!
11285 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11286 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11287 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11288 was not executed, and the compiler (cl) launched a warning:
11289 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11291 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11292 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11294 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11295 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11297 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11298 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11299 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11300 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11301 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11302 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11303 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11304 - added Release configuration in VS projects
11305 - review of compiler an linker options
11306 - VC .exe files are generated in bin_vc directory, not to interfere
11307 with binaries generated from other projects (cygwin, mingw, bcc ...)
11309 * sdcc/src/yacc.dsp: added
11311 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11312 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11313 and insert the version number definitions from .version
11315 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11317 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11318 added - genarate auto-host.h using auto-host_vc_in.h as template
11321 removed from CVS, generated automatically
11323 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11324 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11326 2002-08-11 Borut Razem <borut.razem AT siol.net>
11327 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11329 2002-08-10 Borut Razem <borut.razem AT siol.net>
11330 * src/SDCCmain.c (main):
11331 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11332 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11333 The consequence was that some temporary files were not removed.
11336 unification of code in functions tempfilename() and tempfile():
11337 function tempnam() is defined in Visual Studio 6.0 and .NET
11339 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11341 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11342 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11343 - removed compiler command line option /WX: Treats all warnings as errors
11344 - update a list of source files, included into the project
11346 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11347 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11348 changed project type to Generic Project so that can be correcly converted to VS.NET project
11350 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11352 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11354 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11356 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11357 added return 0 statements after assert() to make compiler happy
11359 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11360 added newline in the def file to keep MSC compiler satisfied
11362 * sdcc/src/z80/gen.c:
11363 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11364 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11365 - solved MSC error in function aopDump()
11367 * sdcc_vc.h: define PREFIX as "\\sdcc"
11369 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11370 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11373 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11374 - Rewrote the register banking algorithm.
11375 - Added pCode live-range analysis to registers (for now, only non-used and
11376 singly-used registers optimized away)
11378 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11380 * 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.

11405 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11407 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11409 2002-03-28 Johan Knol <johan AT balder>
11411 * src/SDCCval.c: fixed bug #532436
11413 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11415 Added "char *Processor" field to the port structure.
11418 Added -p option. Allows port dependent processor to be specified.
11421 Initialized the new field char *Processor field to NULL in all ports
11424 Compiler generated registers for interrupt context saving
11425 were not getting allocated.
11427 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11430 Fixed left shift. Will promote the left side of a left shift
11431 if a) left shifting more than size of operand or b) when assigned
11432 to something size > size of left side
11434 2002-03-14 Scott Dattalo <scott AT dattalo.com>

11438 analysis is restructured. ...
11440 * src/pic/device.h:
11443 * src/pic/device.c:
11444 Added. device.c is a PIC port hack to accomodate variations

11542 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11544 * sdcc/src/SDCCloop.c:
11545 Previous fix was not good. basic blocks that have "break" or "return" are
11546 not really partof a loop , but live ranges used in these blocks should
11547 be live thru the entire loop, so set partOfLoop but don't add them to
11550 2002-02-21 <johan AT FRIJA>
11552 * src/SDCCcse.c: fixed bug #514308
11554 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
