1136 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1138 * device/lib/printf_large.c: removed inline assembly for portability and
1139 readability. Use printf_fast if speed or size are more important.
1140 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1141 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1143 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1145 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1146 prevent compiler warning
1148 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1150 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1151 moved to level 0 and declared as static. Also they are explicit
1152 placed in access bank. This was necessery because some times they
1153 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1154 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1155 optimizations. Currently only compare to unsigned char is implemented,
1156 * src/pic16/gen.c: added fReturnIdx array,
1157 * (struct resolvedIfx) is moved to gen.h and made public,
1158 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1159 * (aopForSym): added an optimization to directly store in stack of
1160 the operand of a SEND iCode,
1161 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1162 but as registers instead (AOP_REG) using the fReturnIdx array,
1163 * (pic16_freeAsmop): remove the freed register from the
1164 _G.sregsAlloc field,
1165 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1166 a compare of 'WREG',
1167 * (pic16_popGetTempRegCond): changed function prototype, now
1168 function takes also a bitVector argument v which holds the current
1169 set of registers that are allocated for stack access by aopForSym,
1170 registers allocated in aopForSym for accessing stack symbols are not
1171 any more part of the functions usedRegs field,
1172 * (genCall): some times aopOp is called for a stack variable to be
1173 send, aopForSym might perform the push, if this is true make sure
1174 that genCall doesn't push the variable twice by testing _G.resDirect,
1175 * (genFunction): changed testing for unspecified interrupt number
1176 from 256 to INTNO_UNSPEC,
1177 * modified selection scheme of frame pointer generation. Previously
1178 if function did use local registers a frame pointer was generated,
1179 now a frame pointer is generated only if function has arguments
1180 (that need PLUSW2 register access), or has stack arguments, or the
1181 compiler is not instructed to omit the frame pointer,
1182 * (genEndFunction): before restoring local registers that were saved
1183 in the function preamble, also restore the registers that *might*
1184 have been allocated for stack access,
1185 * (genRet): removed some old comments,
1186 * (genCmp, the active (RN's) version): added a call to the
1187 pic16_genCmp_special function to perform the compare with a more
1188 robust and optimized way,
1189 * (genInline): a feature has been added in inline code generation,
1190 which allows a wildcard variable substitution when writing inline
1191 assembly. Code is incomplete and experimental therefore undocumented,
1192 * (genCast): changed order of aopOp for result and right to allow
1193 aopForSym to directly load the result if possible,
1194 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1195 perform an optimized compare on some selected special occasions,
1196 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1197 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1198 generate an IVT any more,
1199 * src/pic16/main.c (pic16_optionsTable): added command line option
1201 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1202 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1204 * src/pic16/NOTES: Raphael Neider added in list of active developers
1205 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1206 jumptable_end to prevent bug #,
1207 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1208 inCond and outCond fields,
1209 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1210 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1211 turn off register spilling,
1212 * (packRegsForOneUse): synced with other ports' versions although it
1213 is not used currently,
1214 * (pic16_packRegisters): added an optimization while reading
1215 structure bitfields, some registers may be saved (malloc code is
1216 decreased by 80 bytes)
1218 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1220 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1221 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1222 this can be optimized more?
1224 2005-03-10 Raphael Neider <rneider AT web.de>
1226 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1227 genNearPointerGet): (hopefully) fixed access to bitfields via
1228 pointers (p->bitN = x; and x = p->bitN; failed)
1230 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

1862 Adding support for replacing ljmps with sjmps in jumptables
1863 generated for switch statements. For now you need to set the
1864 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1865 Now 4 algorithms for mcs51 jumptable generation are used:
1866 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1867 addresses loaded pc-relative for up to 112 cases and stack-pushing
1868 target addresses loaded with offset from dptr for up to 256 cases.

1898 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1900 * added libc directory. The current version of LibC contains string
1901 functions, ctype functions and macros and some functions of the
1902 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1903 be extensively tested in the future. Standard disclaimer here.
1904 Library is not automatically build yet. But one can build it by
1905 invoking 'make' inside the libc directory.

1916 * (pic16_storeForReturn): optimized return of 0,
1917 * (genCmp): experimental code for new genCmp which uses PIC18's
1918 special compare&skip instructions. Initial tests fail some times
1919 with variables grater than 1 byte in size, so new code is disabled,
1920 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1922 * (genCast): began a fix to optimize the casting of a bit to another
1923 bit, now assigning a bitfield to another bitfield will fail, sorry,

1932 and 1 for banking instruction,
1933 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1934 caused stop processing pCodes after a inline assembly block,
1935 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

1937 registers when it shouldn't,
1938 * src/pic16/ralloc.c (allocReg): add preliminary support for
1939 supporting a limited set of temporary registers,
1941 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

1947 (genFunction): optimize RECEIVE iCodes in reentrant functions
1949 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4837 * src/SDCCast.c (addCast): added promotion to int
4838 (decorateType): updated call to upCast()
4839 * src/SDCCicode.c (geniCodeLeftShift): removed call to
4840 usualUnaryConversions()
4842 2004-01-26 Michael Hope <michaelh AT juju.net.nz>
4844 * support/regression/tests/literalop.c (mulWrapper): Added a
4845 wrapper to remove integer overflow warnings.
4847 * support/regression/tests/float_trans.c: Made work on host.
4849 * support/regression/ports/ucz80/spec.mk (UCZ80): Made detect the
4852 * support/regression/generate-cases.py (main): Changed from inline
4855 * doc/Makefile (install): Changed to depth first to get rid of
4856 missing directory install warning.
4858 * as/Makefile (install-doc): Made work on Mac.
4860 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
4862 * src/SDCCast.c: added an additional type flow in decorateType() of
4863 opposite direction, see feature request #860006; it's enabled at runtime
4864 by setting the environment variable SDCC_NEWTYPEFLOW
4865 * src/SDCCast.h: changed prototype of decorateType()
4866 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
4867 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
4868 'char' to 'int' can be omitted, if both operands are 'unsigned char';
4869 see feature request #877103
4870 * src/SDCCval.c: updated call of decorateType()
4871 (valBitwise): fixed bug #882876
4872 (valMinus): added promotion
4873 (valLogicAndOr): result is unsigned
4874 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
4875 * src/SDCCsymt.c (computeType),
4876 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
4877 must not cause an unsigned operation
4878 * src/pic/glue (pic14emitRegularMap),

4898 * src/pic/ralloc.h: applied patch from Slade Rich;
4899 added support for multiple code pages and multiple RAM banks on the
4900 PIC 14 port. The ASM files now no longer simply assume all the
4901 code / RAM are in the same page / bank. This means the linker can
4902 safely allocate code/RAM of separate ASM files to different pages/banks.
4903 * doc/sdccman.lyx: added Slade's tips
4904 * src/mcs51/peeph.def: fixed bug #880768

4916 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
4917 strtof is not part of C89 and isn't included with Mac OS X.
4919 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4921 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

4946 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4948 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4949 loaded with the linker search paths (-L arguments) and the libraries
4950 to be linked with the current source (-l arguments). Changes
4951 currently will affect only the pic16 port.
4952 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4953 include path the port specific paths and port specific libraries,
4954 * gplink command now contains the $3 argument,
4955 * src/pic16/device.h,
4956 * src/pic16/device.c,: structure PIC_device is made public and
4957 renamed to PIC16_device, the same for variable Pics which is renamed

4972 Documenting changes from previous commits.
4973 * configure.in (version 1.56),
4974 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4975 when generating output files to configure the pic16 library,
4976 but now I've commented it out, since gputils aren't installed in the
4977 SF compile farm, so library won't compile
4979 * device/lib/Makefile.in (version 1.56): initially I've added in
4980 target 'all' the prerequestive 'model-pic16' so it compiled the
4981 pic16 library, but now I've commented it out for the same reasons
4983 * added targets 'model-pic16' and 'objects-pic16' to compile the
4985 * added target 'port-specific-objects-pic16' to handle the
4986 generated libraries and copy them into the build/ directory
4987 * added target 'clean-intermediate-pic16' to clean intermediate
4988 files into pic16 directory
4989 * in target 'installdirs' added line to create directory pic16 in
4990 the installation path

4993 added lines to copy all header files to installation path,
4994 * in target 'installdirs' added line create directory for pic16
4995 headers in the installation path

5010 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5011 option so that it actually works. Made it specific to the z80, since
5012 the gbz80 doesn't have these kinds of I/O ports.
5014 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5016 * device/include/z180.h,

5040 via literal number. The symbol is placed in the corresponding
5041 position of the data ram
5042 * (pic16_dump_section): relocatable and absolute uninitialized
5043 data are now emitted in sorted order to reduce section naming,
5044 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5045 weren't marked as being in the access bank,
5047 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5049 Added portion of GNU PIC Library under the directory
5050 device/include/pic16 and device/lib/pic16. These files
5051 contain the declarations of SFRs for the PIC18Fxx2 devices.
5052 The directory is initialized via configure from toplevel.

5082 all over. Telling LaTeX to be less strict with word spacing
5083 to better keep the right margin. Changed some notes about
5084 maintainance of the ports in section 3.2.1 - is it OK like this?
5086 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5126 * src/pic16/peeph.def: all peepholes with movff are commented out,
5127 because there is a problem in the pcode peep optimizer,
5128 * src/pic16/ralloc.c: the register allocator can now reuse local

5267 Bug reported from Jesus Calvino-Fraga
5269 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5271 * sdcc.spec: updated
5272 * device/include/Makefile.in: don't install CVS directories
5273 * device/lib/Makefile.in: added removal of CVS directories after install
5274 * doc/Makefile: fixed install, added local_icons
5275 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5276 * src/mcs51/gen.c (genRightShift): fixed bug #870788

5280 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5282 PIC16 port related changes:
5283 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5284 added variable stackPos,
5286 * gen.c: genCall, assignResultValue: added support for
5287 pushing/retrieving function parameters to/from stack,
5288 genFunction,genEndFunction: setup stack frame for the
5290 genAddrOf: will be changed according to bug 863624
5292 * added files genutils.c and genutils.h which contain gen*
5293 debugged and optimised functions extracted from gen.c
5295 * glue.c: added variable 'externs' which holds extern symbols,
5296 pic16emitRegularMap: is modified to properly handle relocatable
5297 symbols under the new scheme,
5298 pic16createInterruptVect: is modified
5299 pic16printPublics: is modified to emit 'global' assembler directives,
5300 added pic16_printExterns to print extern symbols,
5301 pic16glue: initializes stack/frame pointer in the beginning of
5302 the assembly output. Temporary hack, will be corrected later,
5303 because gplink yet does not support stack and SDCC does not
5304 yet support a type of crt0.o object to create the final binary.
5306 * Removed many lines that contain 8051 legacy code.
5307 * The code is finally placed under a 'code' directive.
5308 * Added port specific options.
5310 * _process_pragma: simplified since now we do not need *special*
5311 include file to define SFR registers. But a separate header
5312 will be needed. This will be developed later.
5313 * _pic16_parseOptions: added, parses port specific options:
5314 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5315 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5316 --preplace-udata-with=
5318 * _pic16_setDefaultOptions: modified to initialize section names,
5319 but hack is temporarly out of order since it needs improvement.
5320 * _pic16_genAssemblerPreamble: configuration words are emitted by
5321 their address instead of their name. This part is incomplete and
5322 supports only the 18Fxx2 devices. Other devices will emit an error
5323 during assembly since they do not contain the same set of config
5325 * _pic16_genIVT: is modified,
5327 * pcode.c: added definitions for some hardware registers that are needed
5329 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5330 All PCI entries are updated. Now LFSR is supported.
5331 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5332 * added pic16_newpCodeOpLit2 to support instructions with
5333 two literal arguments
5334 * pic16_pCode2str: corrected code that emits assembler instructions
5335 with two literal operands and those that have an access bit modifier
5336 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5337 this fixes a bug which caused some labels to be lost, when an
5338 assembler directive was added, i.e. banksel,
5339 * pic16_FixRegisterBanking: improved logic that causes the insertion
5341 * InlineFunction: functions that are called once, are not any more
5342 inlined. This can be a port option in the future,
5344 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5346 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5347 hold the corresponding uninitialized symbols,
5348 * pic16_allocProcessorRegister: registers have explicit marked the
5350 * pic16_allocInternalRegister: registers are explicit marked as
5352 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5353 processing list, so bit registers were lost,
5356 * ralloc.h: added field 'accessBank' and original symbol operand
5357 in register definition,
5358 * removed the field isMapped from register definition,
5360 ** Several functions have been removed from various sources:
5361 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5362 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5363 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5364 pic16_assignRelocatableRegisters
5366 ** others have been introduced:
5367 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5368 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5370 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5372 * support/scripts/inc2h.pl: changed definition of BIT_AT
5373 to emit 'sbit at' instead of 'bit at'. This was a request.
5375 PIC16 port related preliminary changes:
5376 * gen.c: prefixed function popRegFromString with
5377 pic16_ and all references to it corrected
5378 * pcode.c: all pic16_pc_* hardware registers prefixed
5379 with underscore (_),
5380 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5381 * ralloc.c: newReg(): when register is REG_SFR then
5382 set address to rIdx,
5383 pic16_allocProcessorRegister(): marks register wasUsed=0
5384 pic16_writeUsedRegs(): added a call to assign processor
5385 registers via pic16_assignFixedRegisters
5387 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5389 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5390 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5391 variables in unused register banks. Also the SSEG is placed
5392 wherever there is enough space for it, and IDATA can be anywhere
5393 in internal RAM. For now compile using -Wl-Y[stack_size].
5394 The mem file is different for this option as well, since it
5395 makes no sense of talking about DSEG lenght.
5397 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5399 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5400 in certain cases, e.g. when ROM assignment, patch provided
5401 from Albert den Haan.

5644 * src/SDCCast.c (decorateType): disabled a transformation I added in
5645 revision 1.188 (access to fields of a structure at an absolute address);
5646 it breaks with bitfields, extern declarations, and gcse analysis.
5647 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
5648 could be assigned through a pointer, so don't complain.

5756 xdata initialization slightly shorter
5758 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6408 copied from genNearPointerSet()
6409 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6410 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

6426 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6427 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

6444 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6446 A few small changes that speed up the peephole optimizer.
6450 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6452 Try to make the peephole optimizer smarter by maintaining
6453 an association between the assembly source code and the
6454 iCodes that originated them. Put this information to use
6455 with a new peephole rule condition "notVolatile" so that
6456 the rules can be aggressive yet still safe.
6461 * src/mcs51/peeph.def
6463 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6467 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6468 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6469 if the left or right operand symbols have the accuse flag set.
6471 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6473 Changed the type of the result of the ! (NOT) operator to char;
6474 previously it returned the same type as the source. This allows
6475 us to eliminate all the genFloatNot functions (all of its target
6476 implementations were very buggy) since !float can use the same
6479 * src/SDCCicode.c (ast2iCode): ! returns char
6480 * src/mcs51/gen.c (genNot, genNotFloat),
6481 * src/ds390/gen.c (genNot, genNotFloat),
6482 * src/z80/gen.c (genNot, genNotFloat),
6483 * src/pic/gen.c (genNot, genNotFloat),
6484 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
6486 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
6488 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6489 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6490 during interrupts. Ensure WSAVE is located at a shared bank address.
6491 2. Fixed page selection in some places
6492 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6493 the registers name strings.
6494 4. Fixed "signed / unsigned compare" compiler warnings.
6495 5. The PIC port manages its own allocation of the general purpose
6496 registers, but makes no attempt to reuse them. As a result when
6497 compiling it soon runs out of general purpose registers. Some
6498 additional code was added to the files pcode.c and device.c to walk
6499 through the function call tree and rename the registers so that they
6509 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6510 genPlus() & genMinus() when the result is the same as left or right

6516 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6518 Made bitfield a distinct type from bit so that bitfields
6519 convert as per ANSI C and bits retain their traditional
6520 boolean style behaviour. Implemented bitfield support in
6528 * src/ds390/gen.c: bit v bitfield split
6529 * src/z80/gen.c: New support for bitfields
6530 * support/regression/tests/bitfields.c: reenabled z80,
6533 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6535 Rules 246.x, 247.x relate to bitfields, the others speed up
6536 access to xdata mapped I/O devices.
6538 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6540 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6542 Cleaned up genPackBits and genUnpackBits and added two helper
6543 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6544 for literal assignments in genPackBits (thanks to Frieder for
6550 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6552 Fixed bug #748310 (pointer to function type mishandled when the
6553 function name is omitted). Also fixed a SIGSEGV when a function
6554 attribute (reentrant, etc) is used on a non-function or on a
6555 function but misplaced before the parameter list.
6557 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6559 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6560 * support/Util/SDCCerr.h,
6561 * support/Util/SDCCerr.c: Added func attr misuse error msg

6582 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6584 Made the constant following the "interrupt" keyword optional. If
6585 omitted, the function will not automatically be given an entry
6586 in the interrupt vector table (similar to #pragma NOIV, but
6587 less syntacticly kludgy). The interrupt number is also now
6588 range checked. Also fixed a bug in the high order bit example
6595 * support/Util/SDCCerr.c
6596 * support/Util/SDCCerr.h
6599 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

6602 * src/SDCCicode.c (operandOperation): rewritten some ops
6603 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6604 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6606 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6607 be re-activated by defining REDUCE_LITERALS)
6608 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6609 unsigned, but are signed by default
6610 * src/SDCCval.c (constVal): rearranged
6611 * src/SDCCval.c (valMod): preliminary fix
6612 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6654 constants are unsigned; added recognition of "u" flag for unsigned
6655 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
6656 * src/SDCCval.c (valDiv, valMod): fixed signdness
6657 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
6658 signedness of modulo, left and right shift

7064 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7065 the regression tests I'm not brave enough to enable 245.b, 245.c
7066 * doc/sdccman.lyx: added latex preamble for hyperref package.
7067 Using pdflatex this will give you a hyperlinked pdf file with
7068 bookmarks. (prepend '%' before /usepackage if this breaks something)

7109 it can be defined with CFLAGS when running configure
7110 * src/SDCCmain.c: fixed compiling + linking with object files
7112 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

7115 added --disable-pic16-port
7116 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7117 * src/SDCCmain.c: linkOptions is changed to set *,
7118 added if/endif conditional macros to remove options help
7119 messages from optionsTable when a port is not configured, added
7120 support for the PIc16 port in the ports table, when executing
7121 the compiler with no port specified on command line, a default
7122 port is selected with the new macro DEFAULT_PORT which is
7123 defined in port.h, in setDefaultOptions() linkOptions is removed
7124 from initialization assignment, since now it is a set,
7125 parseCmdLine uses setParseWithComma for linkOptions, in
7126 linkEdit() linkOptions are accessed with new function indexSet()
7127 which returns the i'th item of a set variable. See SDCCset.c, in
7128 linkEdit() when calling buildCmdLine(), added linkOptions as
7129 last argument. Now users can pass arguments to gplink via the
7130 -Wl option, main() uses pic16glue() to glue up pic16 programs

7142 * src/pic16/glue.c: commented out some error producing lines
7143 * src/pic16/main.c: __config directives are commented out to stop
7144 gpasm complaining and test the linkage with gplink, _linkCmd and
7145 _asmCmd changed to be more gplink and gpasm friendly
7146 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7147 produced an error when parsed, peep rule 12 is added to utilize
7148 movff, but it is commented out since the pCode does not support
7149 yet a command with 2 address arguments
7151 2003-05-18 <johan AT balder>
7153 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7180 2003-05-11 Borut Razem <borut.razem AT siol.net>
7182 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7183 the path of bin directory, so that PATH is the only env. variable, which has to be set
7184 in case of standard installation.
7185 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8255 Changes to aslink (All the changes are marked with 'JCF'):
8257 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8260 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8261 area BSEG. Also moves, if possible, the DATA area down into the internal
8262 ram so more space is available.
8264 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8267 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8268 not bytes. Function summary() which creates a memory usage summary
8269 file with extension .mem. Reports of overlaping stack and small stack
8270 size. If the space for the stack is less than 16 bytes aslink trows a
8273 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8274 the 8051. Option 'y' for memory summary output file.
8276 Changes to sdcc (All the changes are marked with 'JCF'):
8278 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8280 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8281 overlaying area for it (uses RegBankUsed[4]).
8283 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8284 bank zero as used by default. By default aslink locates the stack
8285 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8286 the creation of the .mem file. Delegates the allocation of data area
8287 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8288 the begining of the stack area to aslink.
8290 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8291 glue() in SDCCglue.c creates an area for it.
8293 2002-09-03 Borut Razem <borut.razem AT siol.net>
8294 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8295 sdcc/src/pic/glue.c:
8296 introduced atexit() handler for teporay files removal in case of
8297 errors, assertions, ...
8299 2002-08-29 Borut Razem <borut.razem AT siol.net>
8300 * sdcc/support/cpp2/auto-host_vc_in.h:
8301 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8302 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8303 Maybe there is a similar problem with BORLANDC? It should be checked!
8305 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8306 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8307 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8308 was not executed, and the compiler (cl) launched a warning:
8309 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8311 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8312 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8314 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8315 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8317 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8318 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8319 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8320 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8321 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8322 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8323 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8324 - added Release configuration in VS projects
8325 - review of compiler an linker options
8326 - VC .exe files are generated in bin_vc directory, not to interfere
8327 with binaries generated from other projects (cygwin, mingw, bcc ...)
8329 * sdcc/src/yacc.dsp: added
8331 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8332 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8333 and insert the version number definitions from .version
8335 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8337 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8338 added - genarate auto-host.h using auto-host_vc_in.h as template
8341 removed from CVS, generated automatically
8343 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8344 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8346 2002-08-11 Borut Razem <borut.razem AT siol.net>
8347 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8349 2002-08-10 Borut Razem <borut.razem AT siol.net>
8350 * src/SDCCmain.c (main):
8351 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8352 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8353 The consequence was that some temporary files were not removed.
8356 unification of code in functions tempfilename() and tempfile():
8357 function tempnam() is defined in Visual Studio 6.0 and .NET
8359 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8361 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8362 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8363 - removed compiler command line option /WX: Treats all warnings as errors
8364 - update a list of source files, included into the project
8366 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8367 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8368 changed project type to Generic Project so that can be correcly converted to VS.NET project
8370 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8372 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8374 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8376 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8377 added return 0 statements after assert() to make compiler happy
8379 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8380 added newline in the def file to keep MSC compiler satisfied
8382 * sdcc/src/z80/gen.c:
8383 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8384 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8385 - solved MSC error in function aopDump()
8387 * sdcc_vc.h: define PREFIX as "\\sdcc"
8389 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8390 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

8429 2002-03-28 Johan Knol <johan AT balder>
8431 * src/SDCCval.c: fixed bug #532436
8433 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8435 Added "char *Processor" field to the port structure.
8438 Added -p option. Allows port dependent processor to be specified.
8441 Initialized the new field char *Processor field to NULL in all ports
8444 Compiler generated registers for interrupt context saving
8445 were not getting allocated.
8447 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8450 Fixed left shift. Will promote the left side of a left shift
8451 if a) left shifting more than size of operand or b) when assigned
8452 to something size > size of left side
8454 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8456 tons of changes. Register allocation has been
8457 rewritten. Added customization for the various PICs. Flow

8562 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8564 * sdcc/src/SDCCloop.c:
8565 Previous fix was not good. basic blocks that have "break" or "return" are
8566 not really partof a loop , but live ranges used in these blocks should
8567 be live thru the entire loop, so set partOfLoop but don't add them to
8570 2002-02-21 <johan AT FRIJA>
8572 * src/SDCCcse.c: fixed bug #514308
8574 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

8578 statement inside a loop, it was not being considered part of the loop.
8580 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
8582 2002-02-10 Karl Bongers <karl AT turbobit.com>
8585 Fixed up SDCDB debugger somewhat. Updated debugger/README
8586 with lots of comments and notes.
8588 * device/examples/test2.c:
8589 Fix bug, "red" variable not being initialized(compiler complained).
