1034 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1036 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1037 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1039 One basic decision: e.g. src/clean.mk includes further files. In order
1040 to make this work there are two solutions:
1041 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1042 run configure on them. This way they can use
1043 'include $(srcdir)/port-clean.mk'
1044 - always include clean.mk by the Makefile at the same level. To avoid
1045 that `make clean` tries to include and build Makefile.dep the
1046 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1047 implemented, because now even `make uninstall` doesn't create
1048 Makefile.in. clean.mk could be eliminated by pasting it in
1051 * debugger/mcs51/Makefile.in: build own objects from library sources
1052 (SLIB, SDCC) in current directory
1054 * configure, configure.in: renamed --disable-device-lib-build in
1055 --disable-device-lib; added --enable-doc, the required tools are
1056 searched by configure; added result message; the toolchain for the
1057 belonging ports are now only built, if the port is enabled.
1059 * support/regression/*: all output is written in directory gen, because
1060 the fwk and ports directories don't livet in the build tree using vpath
1062 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1063 --disable-device-lib, added --enable-doc, added section VPATH
1065 * sim/ucsim/configure.in,
1066 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1067 z80 are enabled by default
1069 2006-04-24 Raphael Neider <rneider AT web.de>
1071 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1072 to config word, "pic14_"-prefixed some extern functions
1073 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1074 config word has been found
1075 * src/pic/device.h: added prototypes
1076 * src/pic/pcode.c: added "pic14_"-prefix where needed

1367 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1368 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1369 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1370 allocate asmop as AOP_ACC,
1371 (aopForRemat): added parameter 'bool result' in function declaration,
1372 (pic16_aopGet): return AOP_ACC when accessing WREG,
1373 (pic16_popGetTempReg): minor modification,
1374 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1375 'pic16_allocWithIdx',
1376 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
1377 calling function in absolute addresses,
1378 (genAssign): take into account AOP_ACC asmop,
1379 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
1380 * src/pic16/pcoderegs.c: some debug functions and lines added,
1381 * src/pic16/ralloc.c (decodeRegType): added but commented out,
1382 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1384 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1385 call to allocReg, not by manually allocating a new one,
1386 (pic16_assignRegisters): now before going through the register
1387 allocating functions mark all registers as free. This eliminates some
1388 side effects resulting from peephole parser done earlier in the backbone
1390 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1411 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
1412 (aopForSym, aopOp): increment asmop.allocated if reused,
1413 (freeAsmop): decrement asmop.allocated and check for zero instead of
1415 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1416 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,

1438 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
1440 2006-03-06 Borut Razem <borut.razem AT siol.net>
1442 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1443 made the linker quiet
1445 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1447 * src/pic16/gen.c (genPcall): fixed bug #1443644
1448 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1449 which dumps before the function entry point a data byte which represents
1450 the number of the local variables used by the specified function, added
1451 'xinst' for initial support for Extended Instruction Support,
1452 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1453 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1454 port->fun_prefix anymore (may change later),
1455 (genFunction, genEndFunction): do not store/restore local registers for
1456 _main (this should take care the --main-return command line option in
1458 (genOr): removed some legacy pic-port instructions,
1459 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1460 performing operations with SFR's causes data to be written more than
1461 once to each SFR. Perhaps SFRs should be handled in special cases...
1462 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1464 * src/pic16/main.c (_process_pragma): stack bound checking did not take

1467 --extended or -y for Extended Instruction Support,
1468 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1469 (deassignLRs): *** perhaps the most important change, old 'for' code
1470 (commented out for reference), didn't account for some registers which
1471 were left marked 'not free' after a pointer operation. The change
1472 reduces register usage a lot in some cases

3830 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3832 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3834 * device/lib/printf_large.c: removed inline assembly for portability and
3835 readability. Use printf_fast if speed or size are more important.
3836 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3837 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3839 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3841 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3842 prevent compiler warning
3844 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3846 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3847 moved to level 0 and declared as static. Also they are explicit
3848 placed in access bank. This was necessery because some times they
3849 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3850 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3851 optimizations. Currently only compare to unsigned char is implemented,
3852 * src/pic16/gen.c: added fReturnIdx array,
3853 * (struct resolvedIfx) is moved to gen.h and made public,
3854 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3855 * (aopForSym): added an optimization to directly store in stack of
3856 the operand of a SEND iCode,
3857 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3858 but as registers instead (AOP_REG) using the fReturnIdx array,
3859 * (pic16_freeAsmop): remove the freed register from the
3860 _G.sregsAlloc field,
3861 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3862 a compare of 'WREG',
3863 * (pic16_popGetTempRegCond): changed function prototype, now
3864 function takes also a bitVector argument v which holds the current
3865 set of registers that are allocated for stack access by aopForSym,
3866 registers allocated in aopForSym for accessing stack symbols are not
3867 any more part of the functions usedRegs field,
3868 * (genCall): some times aopOp is called for a stack variable to be
3869 send, aopForSym might perform the push, if this is true make sure
3870 that genCall doesn't push the variable twice by testing _G.resDirect,
3871 * (genFunction): changed testing for unspecified interrupt number
3872 from 256 to INTNO_UNSPEC,
3873 * modified selection scheme of frame pointer generation. Previously
3874 if function did use local registers a frame pointer was generated,
3875 now a frame pointer is generated only if function has arguments
3876 (that need PLUSW2 register access), or has stack arguments, or the
3877 compiler is not instructed to omit the frame pointer,
3878 * (genEndFunction): before restoring local registers that were saved
3879 in the function preamble, also restore the registers that *might*
3880 have been allocated for stack access,
3881 * (genRet): removed some old comments,
3882 * (genCmp, the active (RN's) version): added a call to the
3883 pic16_genCmp_special function to perform the compare with a more
3884 robust and optimized way,
3885 * (genInline): a feature has been added in inline code generation,
3886 which allows a wildcard variable substitution when writing inline
3887 assembly. Code is incomplete and experimental therefore undocumented,
3888 * (genCast): changed order of aopOp for result and right to allow
3889 aopForSym to directly load the result if possible,
3890 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,

4558 Adding support for replacing ljmps with sjmps in jumptables
4559 generated for switch statements. For now you need to set the
4560 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4561 Now 4 algorithms for mcs51 jumptable generation are used:
4562 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4563 addresses loaded pc-relative for up to 112 cases and stack-pushing
4564 target addresses loaded with offset from dptr for up to 256 cases.

4596 * added libc directory. The current version of LibC contains string
4597 functions, ctype functions and macros and some functions of the
4598 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4599 be extensively tested in the future. Standard disclaimer here.
4600 Library is not automatically build yet. But one can build it by

4612 * (pic16_storeForReturn): optimized return of 0,
4613 * (genCmp): experimental code for new genCmp which uses PIC18's
4614 special compare&skip instructions. Initial tests fail some times
4615 with variables grater than 1 byte in size, so new code is disabled,
4616 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4618 * (genCast): began a fix to optimize the casting of a bit to another
4619 bit, now assigning a bitfield to another bitfield will fail, sorry,

4628 and 1 for banking instruction,
4629 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4630 caused stop processing pCodes after a inline assembly block,
4631 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

4633 registers when it shouldn't,
4634 * src/pic16/ralloc.c (allocReg): add preliminary support for
4635 supporting a limited set of temporary registers,
4637 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7645 loaded with the linker search paths (-L arguments) and the libraries
7646 to be linked with the current source (-l arguments). Changes
7647 currently will affect only the pic16 port.
7648 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7649 include path the port specific paths and port specific libraries,
7650 * gplink command now contains the $3 argument,
7651 * src/pic16/device.h,
7652 * src/pic16/device.c,: structure PIC_device is made public and
7653 renamed to PIC16_device, the same for variable Pics which is renamed

7668 Documenting changes from previous commits.
7669 * configure.in (version 1.56),
7670 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7671 when generating output files to configure the pic16 library,
7672 but now I've commented it out, since gputils aren't installed in the
7673 SF compile farm, so library won't compile
7675 * device/lib/Makefile.in (version 1.56): initially I've added in
7676 target 'all' the prerequestive 'model-pic16' so it compiled the
7677 pic16 library, but now I've commented it out for the same reasons
7679 * added targets 'model-pic16' and 'objects-pic16' to compile the
7681 * added target 'port-specific-objects-pic16' to handle the
7682 generated libraries and copy them into the build/ directory
7683 * added target 'clean-intermediate-pic16' to clean intermediate
7684 files into pic16 directory
7685 * in target 'installdirs' added line to create directory pic16 in

7689 added lines to copy all header files to installation path,
7690 * in target 'installdirs' added line create directory for pic16
7691 headers in the installation path

7896 arguments via -W option
7897 * src/pic16/main.c: added $l in _asmCmd, changed extension for
7898 object file from '.rel' to '.o' in port->linker structure,

7930 * src/SDCCast.c (decorateType),
7931 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
7932 LEFT_OP (left shift)
7934 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7936 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7937 (default behaviour).
7939 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7941 A python script to validate compiler diagnostic messages. It can be
7942 used to verify that sdcc complains about bad c source code and
7943 gives a good location of the error.
7944 * support/valdiag/Makefile,
7945 * support/valdiag/valdiag.py,
7946 * support/valdiag/tests/*

7959 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7961 * src/common.h: added ifndef/define/endif macros
7962 around the header file.
7963 Bug reported from Jesus Calvino-Fraga
7965 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7967 * sdcc.spec: updated
7968 * device/include/Makefile.in: don't install CVS directories
7969 * device/lib/Makefile.in: added removal of CVS directories after install
7970 * doc/Makefile: fixed install, added local_icons
7971 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7972 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7973 * src/ds390/gen.c (genRightShift): fixed bug #870788

7976 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7978 PIC16 port related changes:
7979 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7980 added variable stackPos,
7982 * gen.c: genCall, assignResultValue: added support for
7983 pushing/retrieving function parameters to/from stack,
7984 genFunction,genEndFunction: setup stack frame for the
7986 genAddrOf: will be changed according to bug 863624
7988 * added files genutils.c and genutils.h which contain gen*
7989 debugged and optimised functions extracted from gen.c
7991 * glue.c: added variable 'externs' which holds extern symbols,
7992 pic16emitRegularMap: is modified to properly handle relocatable
7993 symbols under the new scheme,
7994 pic16createInterruptVect: is modified
7995 pic16printPublics: is modified to emit 'global' assembler directives,
7996 added pic16_printExterns to print extern symbols,
7997 pic16glue: initializes stack/frame pointer in the beginning of
7998 the assembly output. Temporary hack, will be corrected later,
7999 because gplink yet does not support stack and SDCC does not
8000 yet support a type of crt0.o object to create the final binary.
8002 * Removed many lines that contain 8051 legacy code.
8003 * The code is finally placed under a 'code' directive.
8004 * Added port specific options.
8006 * _process_pragma: simplified since now we do not need *special*
8007 include file to define SFR registers. But a separate header
8008 will be needed. This will be developed later.
8009 * _pic16_parseOptions: added, parses port specific options:
8010 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8011 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8012 --preplace-udata-with=
8014 * _pic16_setDefaultOptions: modified to initialize section names,
8015 but hack is temporarly out of order since it needs improvement.
8016 * _pic16_genAssemblerPreamble: configuration words are emitted by
8017 their address instead of their name. This part is incomplete and
8018 supports only the 18Fxx2 devices. Other devices will emit an error
8019 during assembly since they do not contain the same set of config
8021 * _pic16_genIVT: is modified,
8023 * pcode.c: added definitions for some hardware registers that are needed
8025 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8026 All PCI entries are updated. Now LFSR is supported.
8027 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8028 * added pic16_newpCodeOpLit2 to support instructions with
8029 two literal arguments
8030 * pic16_pCode2str: corrected code that emits assembler instructions
8031 with two literal operands and those that have an access bit modifier
8032 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8033 this fixes a bug which caused some labels to be lost, when an
8034 assembler directive was added, i.e. banksel,
8035 * pic16_FixRegisterBanking: improved logic that causes the insertion
8037 * InlineFunction: functions that are called once, are not any more
8038 inlined. This can be a port option in the future,
8040 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8042 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8043 hold the corresponding uninitialized symbols,
8044 * pic16_allocProcessorRegister: registers have explicit marked the
8046 * pic16_allocInternalRegister: registers are explicit marked as
8048 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8049 processing list, so bit registers were lost,
8052 * ralloc.h: added field 'accessBank' and original symbol operand
8053 in register definition,
8054 * removed the field isMapped from register definition,
8056 ** Several functions have been removed from various sources:
8057 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8058 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8059 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8060 pic16_assignRelocatableRegisters
8062 ** others have been introduced:
8063 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8064 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8066 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8068 * support/scripts/inc2h.pl: changed definition of BIT_AT
8069 to emit 'sbit at' instead of 'bit at'. This was a request.
8071 PIC16 port related preliminary changes:
8072 * gen.c: prefixed function popRegFromString with
8073 pic16_ and all references to it corrected
8074 * pcode.c: all pic16_pc_* hardware registers prefixed
8075 with underscore (_),
8076 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8077 * ralloc.c: newReg(): when register is REG_SFR then
8078 set address to rIdx,
8079 pic16_allocProcessorRegister(): marks register wasUsed=0
8080 pic16_writeUsedRegs(): added a call to assign processor
8081 registers via pic16_assignFixedRegisters
8083 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8085 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8086 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8087 variables in unused register banks. Also the SSEG is placed
8088 wherever there is enough space for it, and IDATA can be anywhere
8089 in internal RAM. For now compile using -Wl-Y[stack_size].
8090 The mem file is different for this option as well, since it
8091 makes no sense of talking about DSEG lenght.
8093 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8095 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8096 in certain cases, e.g. when ROM assignment, patch provided
8097 from Albert den Haan.

8338 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8340 * src/SDCCast.c (decorateType): disabled a transformation I added in
8341 revision 1.188 (access to fields of a structure at an absolute address);
8342 it breaks with bitfields, extern declarations, and gcse analysis.
8343 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8344 could be assigned through a pointer, so don't complain.
8345 * src/SDCCast.c (astErrors),
8347 * src/SDCCglue.c (emitRegularMap): fixed bug #847813
8349 2003-11-26 Vangelis Rokas <vrokas AT otenet.gr>

8355 pre-processor macro, i.e. -DMCU=p18f452
8356 * src/pic16/ralloc.c: renamed packRegisters to pic16_packRegisters,
8357 and modified to handle 'cast' icode similarly to '=' icode

9100 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9101 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9102 fetching of the pointer
9103 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9104 copied from genNearPointerSet()
9105 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9106 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9107 If they pop r0/r1 they must be called in the opposite order than aopOp().
9108 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9109 (resp. --stack-auto), prepared for --xstack

9120 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9122 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9123 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9124 type for bits was changed. It resulted in bit variables becoming
9125 global, which is not permitted in PIC 14 assembly output.
9127 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9129 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9142 A few small changes that speed up the peephole optimizer.
9146 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9148 Try to make the peephole optimizer smarter by maintaining
9149 an association between the assembly source code and the
9150 iCodes that originated them. Put this information to use
9151 with a new peephole rule condition "notVolatile" so that
9152 the rules can be aggressive yet still safe.
9157 * src/mcs51/peeph.def
9159 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9163 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9164 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9165 if the left or right operand symbols have the accuse flag set.
9167 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9169 Changed the type of the result of the ! (NOT) operator to char;
9170 previously it returned the same type as the source. This allows
9171 us to eliminate all the genFloatNot functions (all of its target
9172 implementations were very buggy) since !float can use the same

9184 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9185 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9186 during interrupts. Ensure WSAVE is located at a shared bank address.
9187 2. Fixed page selection in some places
9188 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9189 the registers name strings.
9190 4. Fixed "signed / unsigned compare" compiler warnings.
9191 5. The PIC port manages its own allocation of the general purpose
9192 registers, but makes no attempt to reuse them. As a result when
9193 compiling it soon runs out of general purpose registers. Some
9194 additional code was added to the files pcode.c and device.c to walk
9195 through the function call tree and rename the registers so that they
9205 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9206 genPlus() & genMinus() when the result is the same as left or right

9212 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9214 Made bitfield a distinct type from bit so that bitfields
9215 convert as per ANSI C and bits retain their traditional
9216 boolean style behaviour. Implemented bitfield support in
9224 * src/ds390/gen.c: bit v bitfield split
9225 * src/z80/gen.c: New support for bitfields
9226 * support/regression/tests/bitfields.c: reenabled z80,
9229 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9231 Rules 246.x, 247.x relate to bitfields, the others speed up
9232 access to xdata mapped I/O devices.
9234 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9236 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9238 Cleaned up genPackBits and genUnpackBits and added two helper
9239 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9240 for literal assignments in genPackBits (thanks to Frieder for
9246 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9248 Fixed bug #748310 (pointer to function type mishandled when the
9249 function name is omitted). Also fixed a SIGSEGV when a function
9250 attribute (reentrant, etc) is used on a non-function or on a
9251 function but misplaced before the parameter list.
9253 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9255 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9256 * support/Util/SDCCerr.h,

9278 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9280 Made the constant following the "interrupt" keyword optional. If
9281 omitted, the function will not automatically be given an entry
9282 in the interrupt vector table (similar to #pragma NOIV, but
9283 less syntacticly kludgy). The interrupt number is also now
9284 range checked. Also fixed a bug in the high order bit example

9300 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9302 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9303 be re-activated by defining REDUCE_LITERALS)

9350 constants are unsigned; added recognition of "u" flag for unsigned
9351 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9352 * src/SDCCval.c (valDiv, valMod): fixed signdness
9353 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9354 signedness of modulo, left and right shift

9814 added if/endif conditional macros to remove options help
9815 messages from optionsTable when a port is not configured, added
9816 support for the PIc16 port in the ports table, when executing
9817 the compiler with no port specified on command line, a default
9818 port is selected with the new macro DEFAULT_PORT which is
9819 defined in port.h, in setDefaultOptions() linkOptions is removed
9820 from initialization assignment, since now it is a set,
9821 parseCmdLine uses setParseWithComma for linkOptions, in
9822 linkEdit() linkOptions are accessed with new function indexSet()
9823 which returns the i'th item of a set variable. See SDCCset.c, in
9824 linkEdit() when calling buildCmdLine(), added linkOptions as
9825 last argument. Now users can pass arguments to gplink via the
9826 -Wl option, main() uses pic16glue() to glue up pic16 programs

9840 gpasm complaining and test the linkage with gplink, _linkCmd and
9841 _asmCmd changed to be more gplink and gpasm friendly
9842 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9843 produced an error when parsed, peep rule 12 is added to utilize
9844 movff, but it is commented out since the pCode does not support
9845 yet a command with 2 address arguments
9847 2003-05-18 <johan AT balder>
9849 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

10886 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
10887 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
10888 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
10890 2003-01-04 <johan AT balder>

10904 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10905 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10907 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10908 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10910 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10912 * in /sdcc/as/mcs51/ changed these files in order to create an
10913 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10914 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10915 following files to include the previous two files: aslink.dsp,
10916 Makefile.aslink, Makefile.bcc, and Makefile.in.
10918 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
10919 .adb instead of .cdb
10921 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10923 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
10924 value from option --iram-size.
10926 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10928 * /sdcc/as/mcs51/lklist.c: added boundary check before using
10931 2002-09-18 <wiml AT hhhh.org>
10933 * SDCClrange.h: exposed setFromRange() and setToRange()
10934 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10935 packRegsForAccUse() (bug 542397)
10936 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10937 multiple times and emitting the fetch operations more than once
10938 added aopGetUsesAcc() function to allow binary operators to
10939 fetch their operands in the correct order; made genMinus() emit
10940 compact code for X = LITERAL - Y
10942 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10943 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
10944 sprintf() in line 1267.
10946 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10947 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10950 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10951 Changes to aslink (All the changes are marked with 'JCF'):
10953 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
10956 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
10957 area BSEG. Also moves, if possible, the DATA area down into the internal
10958 ram so more space is available.
10960 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
10963 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
10964 not bytes. Function summary() which creates a memory usage summary
10965 file with extension .mem. Reports of overlaping stack and small stack
10966 size. If the space for the stack is less than 16 bytes aslink trows a
10969 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
10970 the 8051. Option 'y' for memory summary output file.
10972 Changes to sdcc (All the changes are marked with 'JCF'):
10974 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
10976 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
10977 overlaying area for it (uses RegBankUsed[4]).
10979 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
10980 bank zero as used by default. By default aslink locates the stack
10981 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10982 the creation of the .mem file. Delegates the allocation of data area
10983 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10984 the begining of the stack area to aslink.
10986 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
10987 glue() in SDCCglue.c creates an area for it.
10989 2002-09-03 Borut Razem <borut.razem AT siol.net>
10990 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10991 sdcc/src/pic/glue.c:
10992 introduced atexit() handler for teporay files removal in case of
10993 errors, assertions, ...
10995 2002-08-29 Borut Razem <borut.razem AT siol.net>
10996 * sdcc/support/cpp2/auto-host_vc_in.h:
10997 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10998 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10999 Maybe there is a similar problem with BORLANDC? It should be checked!
11001 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11002 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11003 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11004 was not executed, and the compiler (cl) launched a warning:
11005 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11007 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11008 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11010 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11011 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11013 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11014 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11015 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11016 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11017 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11018 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11019 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11020 - added Release configuration in VS projects
11021 - review of compiler an linker options
11022 - VC .exe files are generated in bin_vc directory, not to interfere
11023 with binaries generated from other projects (cygwin, mingw, bcc ...)
11025 * sdcc/src/yacc.dsp: added
11027 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11028 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11029 and insert the version number definitions from .version
11031 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11033 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11034 added - genarate auto-host.h using auto-host_vc_in.h as template
11037 removed from CVS, generated automatically
11039 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11040 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11042 2002-08-11 Borut Razem <borut.razem AT siol.net>
11043 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11045 2002-08-10 Borut Razem <borut.razem AT siol.net>
11046 * src/SDCCmain.c (main):
11047 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11048 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11049 The consequence was that some temporary files were not removed.
11052 unification of code in functions tempfilename() and tempfile():
11053 function tempnam() is defined in Visual Studio 6.0 and .NET
11055 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11057 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11058 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11059 - removed compiler command line option /WX: Treats all warnings as errors
11060 - update a list of source files, included into the project
11062 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11063 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11064 changed project type to Generic Project so that can be correcly converted to VS.NET project
11066 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11068 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11070 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11072 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11073 added return 0 statements after assert() to make compiler happy
11075 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11076 added newline in the def file to keep MSC compiler satisfied
11078 * sdcc/src/z80/gen.c:
11079 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11080 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11081 - solved MSC error in function aopDump()
11083 * sdcc_vc.h: define PREFIX as "\\sdcc"
11085 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11086 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11089 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11090 - Rewrote the register banking algorithm.
11091 - Added pCode live-range analysis to registers (for now, only non-used and
11092 singly-used registers optimized away)
11094 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11096 * 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.

11125 2002-03-28 Johan Knol <johan AT balder>
11127 * src/SDCCval.c: fixed bug #532436
11129 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11131 Added "char *Processor" field to the port structure.
11134 Added -p option. Allows port dependent processor to be specified.
11137 Initialized the new field char *Processor field to NULL in all ports
11140 Compiler generated registers for interrupt context saving
11141 were not getting allocated.
11143 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11146 Fixed left shift. Will promote the left side of a left shift
11147 if a) left shifting more than size of operand or b) when assigned
11148 to something size > size of left side
11150 2002-03-14 Scott Dattalo <scott AT dattalo.com>

11167 2002-03-04 johanknol <johanknol AT manik>
11169 * /src/SDCCval.c: fixed
11171 const unsigned char arr[][2] = { { 0, 1 } };

11261 Previous fix was not good. basic blocks that have "break" or "return" are
11262 not really partof a loop , but live ranges used in these blocks should
11263 be live thru the entire loop, so set partOfLoop but don't add them to
