1334 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1335 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1337 One basic decision: e.g. src/clean.mk includes further files. In order
1338 to make this work there are two solutions:
1339 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1340 run configure on them. This way they can use
1341 'include $(srcdir)/port-clean.mk'
1342 - always include clean.mk by the Makefile at the same level. To avoid
1343 that `make clean` tries to include and build Makefile.dep the
1344 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1345 implemented, because now even `make uninstall` doesn't create
1346 Makefile.in. clean.mk could be eliminated by pasting it in
1349 * debugger/mcs51/Makefile.in: build own objects from library sources
1350 (SLIB, SDCC) in current directory
1352 * configure, configure.in: renamed --disable-device-lib-build in
1353 --disable-device-lib; added --enable-doc, the required tools are

1615 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
1617 * src/mcs51/gen.c (genCall): fixed bug 1457608
1619 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

1638 implemented patch 1120823 Thanks to Willy De la Court (normal
1639 interrupts need an interrupt number now if they are made critical),
1640 and enabled nesting of critical functions though not for gbz80
1641 (genCritical, genEndCritical): added functions
1642 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1643 * src/z80/mappings.i: added "ei" to all mappings

1652 2006-03-16 Raphael Neider <rneider AT web.de>
1654 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1655 the left operand is shorter than the result (c* = lit-c* + int),
1657 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1660 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1662 * src/.version: increased version number to 2.5.5
1663 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1664 linking is done manually in pic16 port's _linkEdit,
1665 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1666 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1667 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1668 allocate asmop as AOP_ACC,
1669 (aopForRemat): added parameter 'bool result' in function declaration,
1670 (pic16_aopGet): return AOP_ACC when accessing WREG,
1671 (pic16_popGetTempReg): minor modification,

1682 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1683 call to allocReg, not by manually allocating a new one,
1684 (pic16_assignRegisters): now before going through the register
1685 allocating functions mark all registers as free. This eliminates some
1686 side effects resulting from peephole parser done earlier in the backbone
1688 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1690 * src/SDCCicode.c (geniCodeLogic),

1736 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
1738 2006-03-06 Borut Razem <borut.razem AT siol.net>
1740 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1741 made the linker quiet
1743 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1745 * src/pic16/gen.c (genPcall): fixed bug #1443644
1746 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1747 which dumps before the function entry point a data byte which represents
1748 the number of the local variables used by the specified function, added
1749 'xinst' for initial support for Extended Instruction Support,
1750 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1751 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1752 port->fun_prefix anymore (may change later),
1753 (genFunction, genEndFunction): do not store/restore local registers for
1754 _main (this should take care the --main-return command line option in
1756 (genOr): removed some legacy pic-port instructions,
1757 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1758 performing operations with SFR's causes data to be written more than
1759 once to each SFR. Perhaps SFRs should be handled in special cases...
1760 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1762 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1763 into account for stack starting position,
1764 (struct OPTIONS pic16_optionsTable): added command line argument
1765 --extended or -y for Extended Instruction Support,
1766 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1767 (deassignLRs): *** perhaps the most important change, old 'for' code
1768 (commented out for reference), didn't account for some registers which
1769 were left marked 'not free' after a pointer operation. The change
1770 reduces register usage a lot in some cases
1772 2006-03-04 Borut Razem <borut.razem AT siol.net>
1774 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

4045 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4046 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4047 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4048 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4049 always available in leading double underscore form. The C99 support is
4050 mostly missing, but it's a start.
4051 * support/regression/tests/bug-227710.c: fixed nonconforming use of

4130 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4132 * device/lib/printf_large.c: removed inline assembly for portability and
4133 readability. Use printf_fast if speed or size are more important.
4134 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4135 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4137 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4139 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4140 prevent compiler warning
4142 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4144 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4145 moved to level 0 and declared as static. Also they are explicit
4146 placed in access bank. This was necessery because some times they
4147 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4148 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4149 optimizations. Currently only compare to unsigned char is implemented,
4150 * src/pic16/gen.c: added fReturnIdx array,
4151 * (struct resolvedIfx) is moved to gen.h and made public,
4152 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4153 * (aopForSym): added an optimization to directly store in stack of
4154 the operand of a SEND iCode,
4155 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4156 but as registers instead (AOP_REG) using the fReturnIdx array,
4157 * (pic16_freeAsmop): remove the freed register from the
4158 _G.sregsAlloc field,
4159 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4160 a compare of 'WREG',
4161 * (pic16_popGetTempRegCond): changed function prototype, now
4162 function takes also a bitVector argument v which holds the current
4163 set of registers that are allocated for stack access by aopForSym,
4164 registers allocated in aopForSym for accessing stack symbols are not
4165 any more part of the functions usedRegs field,
4166 * (genCall): some times aopOp is called for a stack variable to be
4167 send, aopForSym might perform the push, if this is true make sure
4168 that genCall doesn't push the variable twice by testing _G.resDirect,
4169 * (genFunction): changed testing for unspecified interrupt number
4170 from 256 to INTNO_UNSPEC,
4171 * modified selection scheme of frame pointer generation. Previously
4172 if function did use local registers a frame pointer was generated,
4173 now a frame pointer is generated only if function has arguments
4174 (that need PLUSW2 register access), or has stack arguments, or the
4175 compiler is not instructed to omit the frame pointer,
4176 * (genEndFunction): before restoring local registers that were saved
4177 in the function preamble, also restore the registers that *might*
4178 have been allocated for stack access,
4179 * (genRet): removed some old comments,
4180 * (genCmp, the active (RN's) version): added a call to the
4181 pic16_genCmp_special function to perform the compare with a more
4182 robust and optimized way,
4183 * (genInline): a feature has been added in inline code generation,
4184 which allows a wildcard variable substitution when writing inline
4185 assembly. Code is incomplete and experimental therefore undocumented,
4186 * (genCast): changed order of aopOp for result and right to allow
4187 aopForSym to directly load the result if possible,
4188 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4189 perform an optimized compare on some selected special occasions,
4190 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4191 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4192 generate an IVT any more,
4193 * src/pic16/main.c (pic16_optionsTable): added command line option
4195 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4196 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4198 * src/pic16/NOTES: Raphael Neider added in list of active developers
4199 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4200 jumptable_end to prevent bug #,
4201 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4202 inCond and outCond fields,
4203 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4204 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4205 turn off register spilling,
4206 * (packRegsForOneUse): synced with other ports' versions although it
4207 is not used currently,
4208 * (pic16_packRegisters): added an optimization while reading
4209 structure bitfields, some registers may be saved (malloc code is
4210 decreased by 80 bytes)
4212 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4214 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4215 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4216 this can be optimized more?
4218 2005-03-10 Raphael Neider <rneider AT web.de>
4220 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4221 genNearPointerGet): (hopefully) fixed access to bitfields via
4222 pointers (p->bitN = x; and x = p->bitN; failed)
4224 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4856 Adding support for replacing ljmps with sjmps in jumptables
4857 generated for switch statements. For now you need to set the
4858 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4859 Now 4 algorithms for mcs51 jumptable generation are used:
4860 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4861 addresses loaded pc-relative for up to 112 cases and stack-pushing
4862 target addresses loaded with offset from dptr for up to 256 cases.

4892 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4894 * added libc directory. The current version of LibC contains string
4895 functions, ctype functions and macros and some functions of the
4896 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4897 be extensively tested in the future. Standard disclaimer here.
4898 Library is not automatically build yet. But one can build it by
4899 invoking 'make' inside the libc directory.
4900 * added ADC library under libio. Preliminary version yet.

4910 * (pic16_storeForReturn): optimized return of 0,
4911 * (genCmp): experimental code for new genCmp which uses PIC18's
4912 special compare&skip instructions. Initial tests fail some times
4913 with variables grater than 1 byte in size, so new code is disabled,
4914 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4916 * (genCast): began a fix to optimize the casting of a bit to another
4917 bit, now assigning a bitfield to another bitfield will fail, sorry,
4918 * src/pic16/main.c: disabled the use of lr-support feature,
4919 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4926 and 1 for banking instruction,
4927 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4928 caused stop processing pCodes after a inline assembly block,
4929 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

4931 registers when it shouldn't,
4932 * src/pic16/ralloc.c (allocReg): add preliminary support for
4933 supporting a limited set of temporary registers,
4935 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7831 * src/SDCCast.c (addCast): added promotion to int
7832 (decorateType): updated call to upCast()
7833 * src/SDCCicode.c (geniCodeLeftShift): removed call to
7834 usualUnaryConversions()
7836 2004-01-26 Michael Hope <michaelh AT juju.net.nz>
7838 * support/regression/tests/literalop.c (mulWrapper): Added a
7839 wrapper to remove integer overflow warnings.
7841 * support/regression/tests/float_trans.c: Made work on host.
7843 * support/regression/ports/ucz80/spec.mk (UCZ80): Made detect the
7846 * support/regression/generate-cases.py (main): Changed from inline
7849 * doc/Makefile (install): Changed to depth first to get rid of
7850 missing directory install warning.
7852 * as/Makefile (install-doc): Made work on Mac.
7854 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
7856 * src/SDCCast.c: added an additional type flow in decorateType() of
7857 opposite direction, see feature request #860006; it's enabled at runtime
7858 by setting the environment variable SDCC_NEWTYPEFLOW
7859 * src/SDCCast.h: changed prototype of decorateType()
7860 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
7861 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
7862 'char' to 'int' can be omitted, if both operands are 'unsigned char';
7863 see feature request #877103
7864 * src/SDCCval.c: updated call of decorateType()
7865 (valBitwise): fixed bug #882876
7866 (valMinus): added promotion
7867 (valLogicAndOr): result is unsigned
7868 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
7869 * src/SDCCsymt.c (computeType),
7870 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
7871 must not cause an unsigned operation
7872 * src/pic/glue (pic14emitRegularMap),
7873 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
7875 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>

7892 * src/pic/ralloc.h: applied patch from Slade Rich;
7893 added support for multiple code pages and multiple RAM banks on the
7894 PIC 14 port. The ASM files now no longer simply assume all the
7895 code / RAM are in the same page / bank. This means the linker can
7896 safely allocate code/RAM of separate ASM files to different pages/banks.
7897 * doc/sdccman.lyx: added Slade's tips
7898 * src/mcs51/peeph.def: fixed bug #880768

7910 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
7911 strtof is not part of C89 and isn't included with Mac OS X.
7913 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7915 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

7940 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7942 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7943 loaded with the linker search paths (-L arguments) and the libraries
7944 to be linked with the current source (-l arguments). Changes
7945 currently will affect only the pic16 port.
7946 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7947 include path the port specific paths and port specific libraries,
7948 * gplink command now contains the $3 argument,
7949 * src/pic16/device.h,
7950 * src/pic16/device.c,: structure PIC_device is made public and
7951 renamed to PIC16_device, the same for variable Pics which is renamed

7966 Documenting changes from previous commits.
7967 * configure.in (version 1.56),
7968 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7969 when generating output files to configure the pic16 library,
7970 but now I've commented it out, since gputils aren't installed in the
7971 SF compile farm, so library won't compile
7973 * device/lib/Makefile.in (version 1.56): initially I've added in
7974 target 'all' the prerequestive 'model-pic16' so it compiled the
7975 pic16 library, but now I've commented it out for the same reasons
7977 * added targets 'model-pic16' and 'objects-pic16' to compile the
7979 * added target 'port-specific-objects-pic16' to handle the
7980 generated libraries and copy them into the build/ directory
7981 * added target 'clean-intermediate-pic16' to clean intermediate
7982 files into pic16 directory
7983 * in target 'installdirs' added line to create directory pic16 in
7984 the installation path
7986 * device/include/Makefile.in (version 1.11): in target 'install'
7987 added lines to copy all header files to installation path,
7988 * in target 'installdirs' added line create directory for pic16
7989 headers in the installation path

8004 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8005 option so that it actually works. Made it specific to the z80, since
8006 the gbz80 doesn't have these kinds of I/O ports.
8008 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8010 * device/include/z180.h,

8032 Mainly changes to support compilation of the device libraries
8033 * src/pic16/device.c: stack is allocated via symbol and not
8034 via literal number. The symbol is placed in the corresponding
8035 position of the data ram
8036 * (pic16_dump_section): relocatable and absolute uninitialized
8037 data are now emitted in sorted order to reduce section naming,
8038 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8039 weren't marked as being in the access bank,
8041 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8043 Added portion of GNU PIC Library under the directory
8044 device/include/pic16 and device/lib/pic16. These files
8045 contain the declarations of SFRs for the PIC18Fxx2 devices.
8046 The directory is initialized via configure from toplevel.

8076 all over. Telling LaTeX to be less strict with word spacing
8077 to better keep the right margin. Changed some notes about
8078 maintainance of the ports in section 3.2.1 - is it OK like this?
8080 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8120 * src/pic16/peeph.def: all peepholes with movff are commented out,
8121 because there is a problem in the pcode peep optimizer,
8122 * src/pic16/ralloc.c: the register allocator can now reuse local

8261 Bug reported from Jesus Calvino-Fraga
8263 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8265 * sdcc.spec: updated
8266 * device/include/Makefile.in: don't install CVS directories
8267 * device/lib/Makefile.in: added removal of CVS directories after install
8268 * doc/Makefile: fixed install, added local_icons
8269 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8270 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8271 * src/ds390/gen.c (genRightShift): fixed bug #870788

8274 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8276 PIC16 port related changes:
8277 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8278 added variable stackPos,
8280 * gen.c: genCall, assignResultValue: added support for
8281 pushing/retrieving function parameters to/from stack,
8282 genFunction,genEndFunction: setup stack frame for the
8284 genAddrOf: will be changed according to bug 863624
8286 * added files genutils.c and genutils.h which contain gen*
8287 debugged and optimised functions extracted from gen.c
8289 * glue.c: added variable 'externs' which holds extern symbols,
8290 pic16emitRegularMap: is modified to properly handle relocatable
8291 symbols under the new scheme,
8292 pic16createInterruptVect: is modified
8293 pic16printPublics: is modified to emit 'global' assembler directives,
8294 added pic16_printExterns to print extern symbols,
8295 pic16glue: initializes stack/frame pointer in the beginning of
8296 the assembly output. Temporary hack, will be corrected later,
8297 because gplink yet does not support stack and SDCC does not
8298 yet support a type of crt0.o object to create the final binary.
8300 * Removed many lines that contain 8051 legacy code.
8301 * The code is finally placed under a 'code' directive.
8302 * Added port specific options.
8304 * _process_pragma: simplified since now we do not need *special*
8305 include file to define SFR registers. But a separate header
8306 will be needed. This will be developed later.
8307 * _pic16_parseOptions: added, parses port specific options:
8308 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8309 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8310 --preplace-udata-with=
8312 * _pic16_setDefaultOptions: modified to initialize section names,
8313 but hack is temporarly out of order since it needs improvement.
8314 * _pic16_genAssemblerPreamble: configuration words are emitted by
8315 their address instead of their name. This part is incomplete and
8316 supports only the 18Fxx2 devices. Other devices will emit an error
8317 during assembly since they do not contain the same set of config
8319 * _pic16_genIVT: is modified,
8321 * pcode.c: added definitions for some hardware registers that are needed
8323 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8324 All PCI entries are updated. Now LFSR is supported.
8325 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8326 * added pic16_newpCodeOpLit2 to support instructions with
8327 two literal arguments
8328 * pic16_pCode2str: corrected code that emits assembler instructions
8329 with two literal operands and those that have an access bit modifier
8330 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8331 this fixes a bug which caused some labels to be lost, when an
8332 assembler directive was added, i.e. banksel,
8333 * pic16_FixRegisterBanking: improved logic that causes the insertion
8335 * InlineFunction: functions that are called once, are not any more
8336 inlined. This can be a port option in the future,
8338 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8340 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8341 hold the corresponding uninitialized symbols,
8342 * pic16_allocProcessorRegister: registers have explicit marked the
8344 * pic16_allocInternalRegister: registers are explicit marked as
8346 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8347 processing list, so bit registers were lost,
8350 * ralloc.h: added field 'accessBank' and original symbol operand
8351 in register definition,
8352 * removed the field isMapped from register definition,
8354 ** Several functions have been removed from various sources:
8355 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8356 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8357 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8358 pic16_assignRelocatableRegisters
8360 ** others have been introduced:
8361 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8362 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8364 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8366 * support/scripts/inc2h.pl: changed definition of BIT_AT
8367 to emit 'sbit at' instead of 'bit at'. This was a request.
8369 PIC16 port related preliminary changes:
8370 * gen.c: prefixed function popRegFromString with
8371 pic16_ and all references to it corrected
8372 * pcode.c: all pic16_pc_* hardware registers prefixed
8373 with underscore (_),
8374 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8375 * ralloc.c: newReg(): when register is REG_SFR then
8376 set address to rIdx,
8377 pic16_allocProcessorRegister(): marks register wasUsed=0
8378 pic16_writeUsedRegs(): added a call to assign processor
8379 registers via pic16_assignFixedRegisters
8381 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8383 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8384 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8385 variables in unused register banks. Also the SSEG is placed
8386 wherever there is enough space for it, and IDATA can be anywhere
8387 in internal RAM. For now compile using -Wl-Y[stack_size].
8388 The mem file is different for this option as well, since it
8389 makes no sense of talking about DSEG lenght.
8391 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8393 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8394 in certain cases, e.g. when ROM assignment, patch provided
8395 from Albert den Haan.

8638 * src/SDCCast.c (decorateType): disabled a transformation I added in
8639 revision 1.188 (access to fields of a structure at an absolute address);
8640 it breaks with bitfields, extern declarations, and gcse analysis.
8641 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8642 could be assigned through a pointer, so don't complain.

8750 xdata initialization slightly shorter
8752 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9402 copied from genNearPointerSet()
9403 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9404 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

9420 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9421 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9422 type for bits was changed. It resulted in bit variables becoming
9423 global, which is not permitted in PIC 14 assembly output.
9425 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9427 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9431 Z80 and MCS51 linkers complaint if a public symbol is defined
9432 in more than one library module:
9436 * as/mcs51/Makefile.in
9438 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9440 A few small changes that speed up the peephole optimizer.
9444 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9446 Try to make the peephole optimizer smarter by maintaining
9447 an association between the assembly source code and the
9448 iCodes that originated them. Put this information to use
9449 with a new peephole rule condition "notVolatile" so that
9450 the rules can be aggressive yet still safe.
9455 * src/mcs51/peeph.def
9457 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9461 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9462 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9463 if the left or right operand symbols have the accuse flag set.
9465 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9467 Changed the type of the result of the ! (NOT) operator to char;
9468 previously it returned the same type as the source. This allows
9469 us to eliminate all the genFloatNot functions (all of its target
9470 implementations were very buggy) since !float can use the same
9473 * src/SDCCicode.c (ast2iCode): ! returns char
9474 * src/mcs51/gen.c (genNot, genNotFloat),
9475 * src/ds390/gen.c (genNot, genNotFloat),
9476 * src/z80/gen.c (genNot, genNotFloat),
9477 * src/pic/gen.c (genNot, genNotFloat),
9478 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
9480 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
9482 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9483 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9484 during interrupts. Ensure WSAVE is located at a shared bank address.
9485 2. Fixed page selection in some places
9486 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9487 the registers name strings.
9488 4. Fixed "signed / unsigned compare" compiler warnings.
9489 5. The PIC port manages its own allocation of the general purpose
9490 registers, but makes no attempt to reuse them. As a result when
9491 compiling it soon runs out of general purpose registers. Some
9492 additional code was added to the files pcode.c and device.c to walk
9493 through the function call tree and rename the registers so that they
9503 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9504 genPlus() & genMinus() when the result is the same as left or right

9510 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9512 Made bitfield a distinct type from bit so that bitfields
9513 convert as per ANSI C and bits retain their traditional
9514 boolean style behaviour. Implemented bitfield support in
9522 * src/ds390/gen.c: bit v bitfield split
9523 * src/z80/gen.c: New support for bitfields
9524 * support/regression/tests/bitfields.c: reenabled z80,
9527 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9529 Rules 246.x, 247.x relate to bitfields, the others speed up
9530 access to xdata mapped I/O devices.
9532 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9534 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9536 Cleaned up genPackBits and genUnpackBits and added two helper
9537 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9538 for literal assignments in genPackBits (thanks to Frieder for
9544 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9546 Fixed bug #748310 (pointer to function type mishandled when the
9547 function name is omitted). Also fixed a SIGSEGV when a function
9548 attribute (reentrant, etc) is used on a non-function or on a
9549 function but misplaced before the parameter list.
9551 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9553 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9554 * support/Util/SDCCerr.h,
9555 * support/Util/SDCCerr.c: Added func attr misuse error msg

9576 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9578 Made the constant following the "interrupt" keyword optional. If
9579 omitted, the function will not automatically be given an entry
9580 in the interrupt vector table (similar to #pragma NOIV, but
9581 less syntacticly kludgy). The interrupt number is also now
9582 range checked. Also fixed a bug in the high order bit example
9589 * support/Util/SDCCerr.c
9590 * support/Util/SDCCerr.h
9593 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

9596 * src/SDCCicode.c (operandOperation): rewritten some ops
9597 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9598 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9600 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9601 be re-activated by defining REDUCE_LITERALS)
9602 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9603 unsigned, but are signed by default
9604 * src/SDCCval.c (constVal): rearranged
9605 * src/SDCCval.c (valMod): preliminary fix
9606 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9648 constants are unsigned; added recognition of "u" flag for unsigned
9649 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9650 * src/SDCCval.c (valDiv, valMod): fixed signdness
9651 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9652 signedness of modulo, left and right shift

10112 added if/endif conditional macros to remove options help
10113 messages from optionsTable when a port is not configured, added
10114 support for the PIc16 port in the ports table, when executing
10115 the compiler with no port specified on command line, a default
10116 port is selected with the new macro DEFAULT_PORT which is
10117 defined in port.h, in setDefaultOptions() linkOptions is removed
10118 from initialization assignment, since now it is a set,
10119 parseCmdLine uses setParseWithComma for linkOptions, in
10120 linkEdit() linkOptions are accessed with new function indexSet()
10121 which returns the i'th item of a set variable. See SDCCset.c, in
10122 linkEdit() when calling buildCmdLine(), added linkOptions as
10123 last argument. Now users can pass arguments to gplink via the
10124 -Wl option, main() uses pic16glue() to glue up pic16 programs

10137 * src/pic16/main.c: __config directives are commented out to stop
10138 gpasm complaining and test the linkage with gplink, _linkCmd and
10139 _asmCmd changed to be more gplink and gpasm friendly
10140 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10141 produced an error when parsed, peep rule 12 is added to utilize
10142 movff, but it is commented out since the pCode does not support
10143 yet a command with 2 address arguments
10145 2003-05-18 <johan AT balder>
10147 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11197 * support/regression/tests/bug-524697.c: fit mem usage into 8032
11199 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11200 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
11202 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11203 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11205 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11206 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11208 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11210 * in /sdcc/as/mcs51/ changed these files in order to create an
11211 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11212 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11213 following files to include the previous two files: aslink.dsp,
11214 Makefile.aslink, Makefile.bcc, and Makefile.in.
11216 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11217 .adb instead of .cdb
11219 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11221 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11222 value from option --iram-size.
11224 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11226 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11229 2002-09-18 <wiml AT hhhh.org>
11231 * SDCClrange.h: exposed setFromRange() and setToRange()
11232 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11233 packRegsForAccUse() (bug 542397)
11234 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11235 multiple times and emitting the fetch operations more than once
11236 added aopGetUsesAcc() function to allow binary operators to
11237 fetch their operands in the correct order; made genMinus() emit
11238 compact code for X = LITERAL - Y
11240 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11241 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11242 sprintf() in line 1267.
11244 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11245 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11248 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11249 Changes to aslink (All the changes are marked with 'JCF'):
11251 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11254 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11255 area BSEG. Also moves, if possible, the DATA area down into the internal
11256 ram so more space is available.
11258 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11261 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11262 not bytes. Function summary() which creates a memory usage summary
11263 file with extension .mem. Reports of overlaping stack and small stack
11264 size. If the space for the stack is less than 16 bytes aslink trows a
11267 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11268 the 8051. Option 'y' for memory summary output file.
11270 Changes to sdcc (All the changes are marked with 'JCF'):
11272 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11274 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11275 overlaying area for it (uses RegBankUsed[4]).
11277 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11278 bank zero as used by default. By default aslink locates the stack
11279 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11280 the creation of the .mem file. Delegates the allocation of data area
11281 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11282 the begining of the stack area to aslink.
11284 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11285 glue() in SDCCglue.c creates an area for it.
11287 2002-09-03 Borut Razem <borut.razem AT siol.net>
11288 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11289 sdcc/src/pic/glue.c:
11290 introduced atexit() handler for teporay files removal in case of
11291 errors, assertions, ...
11293 2002-08-29 Borut Razem <borut.razem AT siol.net>
11294 * sdcc/support/cpp2/auto-host_vc_in.h:
11295 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11296 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11297 Maybe there is a similar problem with BORLANDC? It should be checked!
11299 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11300 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11301 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11302 was not executed, and the compiler (cl) launched a warning:
11303 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11305 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11306 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11308 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11309 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11311 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11312 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11313 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11314 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11315 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11316 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11317 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11318 - added Release configuration in VS projects
11319 - review of compiler an linker options
11320 - VC .exe files are generated in bin_vc directory, not to interfere
11321 with binaries generated from other projects (cygwin, mingw, bcc ...)
11323 * sdcc/src/yacc.dsp: added
11325 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11326 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11327 and insert the version number definitions from .version
11329 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11331 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11332 added - genarate auto-host.h using auto-host_vc_in.h as template
11335 removed from CVS, generated automatically
11337 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11338 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11340 2002-08-11 Borut Razem <borut.razem AT siol.net>
11341 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11343 2002-08-10 Borut Razem <borut.razem AT siol.net>
11344 * src/SDCCmain.c (main):
11345 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11346 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11347 The consequence was that some temporary files were not removed.
11350 unification of code in functions tempfilename() and tempfile():
11351 function tempnam() is defined in Visual Studio 6.0 and .NET
11353 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11355 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11356 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11357 - removed compiler command line option /WX: Treats all warnings as errors
11358 - update a list of source files, included into the project
11360 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11361 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11362 changed project type to Generic Project so that can be correcly converted to VS.NET project
11364 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11366 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11368 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11370 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11371 added return 0 statements after assert() to make compiler happy
11373 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11374 added newline in the def file to keep MSC compiler satisfied
11376 * sdcc/src/z80/gen.c:
11377 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11378 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11379 - solved MSC error in function aopDump()
11381 * sdcc_vc.h: define PREFIX as "\\sdcc"
11383 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11384 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11387 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11388 - Rewrote the register banking algorithm.
11389 - Added pCode live-range analysis to registers (for now, only non-used and
11390 singly-used registers optimized away)
11392 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11394 * 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.

11421 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11423 2002-03-28 Johan Knol <johan AT balder>
11425 * src/SDCCval.c: fixed bug #532436
11427 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11429 Added "char *Processor" field to the port structure.
11432 Added -p option. Allows port dependent processor to be specified.
11435 Initialized the new field char *Processor field to NULL in all ports
11438 Compiler generated registers for interrupt context saving
11439 were not getting allocated.
11441 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11444 Fixed left shift. Will promote the left side of a left shift
11445 if a) left shifting more than size of operand or b) when assigned
11446 to something size > size of left side
11448 2002-03-14 Scott Dattalo <scott AT dattalo.com>

11556 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11558 * sdcc/src/SDCCloop.c:
11559 Previous fix was not good. basic blocks that have "break" or "return" are
11560 not really partof a loop , but live ranges used in these blocks should
11561 be live thru the entire loop, so set partOfLoop but don't add them to
11564 2002-02-21 <johan AT FRIJA>
11566 * src/SDCCcse.c: fixed bug #514308
11568 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
