1022 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1024 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1025 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1027 One basic decision: e.g. src/clean.mk includes further files. In order
1028 to make this work there are two solutions:
1029 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1030 run configure on them. This way they can use
1031 'include $(srcdir)/port-clean.mk'
1032 - always include clean.mk by the Makefile at the same level. To avoid
1033 that `make clean` tries to include and build Makefile.dep the
1034 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1035 implemented, because now even `make uninstall` doesn't create
1036 Makefile.in. clean.mk could be eliminated by pasting it in
1039 * debugger/mcs51/Makefile.in: build own objects from library sources
1040 (SLIB, SDCC) in current directory
1042 * configure, configure.in: renamed --disable-device-lib-build in
1043 --disable-device-lib; added --enable-doc, the required tools are
1044 searched by configure; added result message; the toolchain for the
1045 belonging ports are now only built, if the port is enabled.
1047 * support/regression/*: all output is written in directory gen, because
1048 the fwk and ports directories don't livet in the build tree using vpath
1050 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1051 --disable-device-lib, added --enable-doc, added section VPATH
1053 * sim/ucsim/configure.in,
1054 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1055 z80 are enabled by default
1057 2006-04-24 Raphael Neider <rneider AT web.de>
1059 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1060 to config word, "pic14_"-prefixed some extern functions
1061 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1062 config word has been found
1063 * src/pic/device.h: added prototypes
1064 * src/pic/pcode.c: added "pic14_"-prefix where needed

1082 (pCodeRegOptimizeRegUsage): fixed typo in comment

1375 allocating functions mark all registers as free. This eliminates some
1376 side effects resulting from peephole parser done earlier in the backbone

1426 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
1428 2006-03-06 Borut Razem <borut.razem AT siol.net>
1430 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1431 made the linker quiet
1433 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>

1436 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1437 which dumps before the function entry point a data byte which represents
1438 the number of the local variables used by the specified function, added
1439 'xinst' for initial support for Extended Instruction Support,
1440 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1441 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1442 port->fun_prefix anymore (may change later),
1443 (genFunction, genEndFunction): do not store/restore local registers for
1444 _main (this should take care the --main-return command line option in
1446 (genOr): removed some legacy pic-port instructions,
1447 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1448 performing operations with SFR's causes data to be written more than

1457 (deassignLRs): *** perhaps the most important change, old 'for' code
1458 (commented out for reference), didn't account for some registers which
1459 were left marked 'not free' after a pointer operation. The change
1460 reduces register usage a lot in some cases

3742 reserved identifier "__data".
3744 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

3818 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3820 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3822 * device/lib/printf_large.c: removed inline assembly for portability and
3823 readability. Use printf_fast if speed or size are more important.
3824 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3825 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3827 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3829 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3830 prevent compiler warning
3832 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3834 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3835 moved to level 0 and declared as static. Also they are explicit
3836 placed in access bank. This was necessery because some times they
3837 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3838 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3839 optimizations. Currently only compare to unsigned char is implemented,
3840 * src/pic16/gen.c: added fReturnIdx array,
3841 * (struct resolvedIfx) is moved to gen.h and made public,
3842 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3843 * (aopForSym): added an optimization to directly store in stack of
3844 the operand of a SEND iCode,
3845 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3846 but as registers instead (AOP_REG) using the fReturnIdx array,
3847 * (pic16_freeAsmop): remove the freed register from the
3848 _G.sregsAlloc field,
3849 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3850 a compare of 'WREG',
3851 * (pic16_popGetTempRegCond): changed function prototype, now
3852 function takes also a bitVector argument v which holds the current
3853 set of registers that are allocated for stack access by aopForSym,
3854 registers allocated in aopForSym for accessing stack symbols are not
3855 any more part of the functions usedRegs field,
3856 * (genCall): some times aopOp is called for a stack variable to be
3857 send, aopForSym might perform the push, if this is true make sure
3858 that genCall doesn't push the variable twice by testing _G.resDirect,
3859 * (genFunction): changed testing for unspecified interrupt number
3860 from 256 to INTNO_UNSPEC,
3861 * modified selection scheme of frame pointer generation. Previously
3862 if function did use local registers a frame pointer was generated,
3863 now a frame pointer is generated only if function has arguments
3864 (that need PLUSW2 register access), or has stack arguments, or the
3865 compiler is not instructed to omit the frame pointer,
3866 * (genEndFunction): before restoring local registers that were saved
3867 in the function preamble, also restore the registers that *might*
3868 have been allocated for stack access,
3869 * (genRet): removed some old comments,
3870 * (genCmp, the active (RN's) version): added a call to the
3871 pic16_genCmp_special function to perform the compare with a more
3872 robust and optimized way,
3873 * (genInline): a feature has been added in inline code generation,
3874 which allows a wildcard variable substitution when writing inline
3875 assembly. Code is incomplete and experimental therefore undocumented,
3876 * (genCast): changed order of aopOp for result and right to allow
3877 aopForSym to directly load the result if possible,
3878 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3879 perform an optimized compare on some selected special occasions,
3880 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3881 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3882 generate an IVT any more,
3883 * src/pic16/main.c (pic16_optionsTable): added command line option
3885 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3886 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3888 * src/pic16/NOTES: Raphael Neider added in list of active developers
3889 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and

4546 Adding support for replacing ljmps with sjmps in jumptables
4547 generated for switch statements. For now you need to set the
4548 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4549 Now 4 algorithms for mcs51 jumptable generation are used:
4550 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4551 addresses loaded pc-relative for up to 112 cases and stack-pushing
4552 target addresses loaded with offset from dptr for up to 256 cases.

4582 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4584 * added libc directory. The current version of LibC contains string
4585 functions, ctype functions and macros and some functions of the
4586 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4587 be extensively tested in the future. Standard disclaimer here.
4588 Library is not automatically build yet. But one can build it by
4589 invoking 'make' inside the libc directory.

4600 * (pic16_storeForReturn): optimized return of 0,
4601 * (genCmp): experimental code for new genCmp which uses PIC18's
4602 special compare&skip instructions. Initial tests fail some times
4603 with variables grater than 1 byte in size, so new code is disabled,
4604 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4606 * (genCast): began a fix to optimize the casting of a bit to another
4607 bit, now assigning a bitfield to another bitfield will fail, sorry,

4616 and 1 for banking instruction,
4617 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4618 caused stop processing pCodes after a inline assembly block,
4619 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

4621 registers when it shouldn't,
4622 * src/pic16/ralloc.c (allocReg): add preliminary support for
4623 supporting a limited set of temporary registers,
4625 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7633 loaded with the linker search paths (-L arguments) and the libraries
7634 to be linked with the current source (-l arguments). Changes
7635 currently will affect only the pic16 port.
7636 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7637 include path the port specific paths and port specific libraries,
7638 * gplink command now contains the $3 argument,
7639 * src/pic16/device.h,

7656 Documenting changes from previous commits.
7657 * configure.in (version 1.56),
7658 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7659 when generating output files to configure the pic16 library,
7660 but now I've commented it out, since gputils aren't installed in the
7661 SF compile farm, so library won't compile
7663 * device/lib/Makefile.in (version 1.56): initially I've added in
7664 target 'all' the prerequestive 'model-pic16' so it compiled the
7665 pic16 library, but now I've commented it out for the same reasons
7667 * added targets 'model-pic16' and 'objects-pic16' to compile the
7669 * added target 'port-specific-objects-pic16' to handle the
7670 generated libraries and copy them into the build/ directory
7671 * added target 'clean-intermediate-pic16' to clean intermediate
7672 files into pic16 directory
7673 * in target 'installdirs' added line to create directory pic16 in

7918 * src/SDCCast.c (decorateType),
7919 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
7920 LEFT_OP (left shift)
7922 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7924 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7925 (default behaviour).
7927 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7929 A python script to validate compiler diagnostic messages. It can be
7930 used to verify that sdcc complains about bad c source code and
7931 gives a good location of the error.
7932 * support/valdiag/Makefile,
7933 * support/valdiag/valdiag.py,
7934 * support/valdiag/tests/*
7936 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7947 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7949 * src/common.h: added ifndef/define/endif macros
7950 around the header file.
7951 Bug reported from Jesus Calvino-Fraga
7953 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7955 * sdcc.spec: updated
7956 * device/include/Makefile.in: don't install CVS directories
7957 * device/lib/Makefile.in: added removal of CVS directories after install
7958 * doc/Makefile: fixed install, added local_icons
7959 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7960 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7961 * src/ds390/gen.c (genRightShift): fixed bug #870788
7962 * src/SDCCast.c (decorateType): fixed bug #870781
7964 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7966 PIC16 port related changes:
7967 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7968 added variable stackPos,
7970 * gen.c: genCall, assignResultValue: added support for
7971 pushing/retrieving function parameters to/from stack,
7972 genFunction,genEndFunction: setup stack frame for the
7974 genAddrOf: will be changed according to bug 863624
7976 * added files genutils.c and genutils.h which contain gen*
7977 debugged and optimised functions extracted from gen.c
7979 * glue.c: added variable 'externs' which holds extern symbols,
7980 pic16emitRegularMap: is modified to properly handle relocatable
7981 symbols under the new scheme,
7982 pic16createInterruptVect: is modified
7983 pic16printPublics: is modified to emit 'global' assembler directives,
7984 added pic16_printExterns to print extern symbols,
7985 pic16glue: initializes stack/frame pointer in the beginning of
7986 the assembly output. Temporary hack, will be corrected later,
7987 because gplink yet does not support stack and SDCC does not
7988 yet support a type of crt0.o object to create the final binary.
7990 * Removed many lines that contain 8051 legacy code.
7991 * The code is finally placed under a 'code' directive.
7992 * Added port specific options.
7994 * _process_pragma: simplified since now we do not need *special*
7995 include file to define SFR registers. But a separate header
7996 will be needed. This will be developed later.
7997 * _pic16_parseOptions: added, parses port specific options:
7998 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7999 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8000 --preplace-udata-with=
8002 * _pic16_setDefaultOptions: modified to initialize section names,
8003 but hack is temporarly out of order since it needs improvement.
8004 * _pic16_genAssemblerPreamble: configuration words are emitted by
8005 their address instead of their name. This part is incomplete and
8006 supports only the 18Fxx2 devices. Other devices will emit an error
8007 during assembly since they do not contain the same set of config
8009 * _pic16_genIVT: is modified,
8011 * pcode.c: added definitions for some hardware registers that are needed
8013 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8014 All PCI entries are updated. Now LFSR is supported.
8015 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8016 * added pic16_newpCodeOpLit2 to support instructions with
8017 two literal arguments
8018 * pic16_pCode2str: corrected code that emits assembler instructions
8019 with two literal operands and those that have an access bit modifier
8020 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8021 this fixes a bug which caused some labels to be lost, when an
8022 assembler directive was added, i.e. banksel,
8023 * pic16_FixRegisterBanking: improved logic that causes the insertion
8025 * InlineFunction: functions that are called once, are not any more
8026 inlined. This can be a port option in the future,
8028 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8030 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8031 hold the corresponding uninitialized symbols,
8032 * pic16_allocProcessorRegister: registers have explicit marked the
8034 * pic16_allocInternalRegister: registers are explicit marked as
8036 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8037 processing list, so bit registers were lost,
8040 * ralloc.h: added field 'accessBank' and original symbol operand
8041 in register definition,
8042 * removed the field isMapped from register definition,
8044 ** Several functions have been removed from various sources:
8045 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8046 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8047 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8048 pic16_assignRelocatableRegisters
8050 ** others have been introduced:
8051 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8052 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8054 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8056 * support/scripts/inc2h.pl: changed definition of BIT_AT
8057 to emit 'sbit at' instead of 'bit at'. This was a request.
8059 PIC16 port related preliminary changes:
8060 * gen.c: prefixed function popRegFromString with
8061 pic16_ and all references to it corrected
8062 * pcode.c: all pic16_pc_* hardware registers prefixed
8063 with underscore (_),
8064 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8065 * ralloc.c: newReg(): when register is REG_SFR then
8066 set address to rIdx,
8067 pic16_allocProcessorRegister(): marks register wasUsed=0
8068 pic16_writeUsedRegs(): added a call to assign processor
8069 registers via pic16_assignFixedRegisters
8071 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8073 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8074 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8075 variables in unused register banks. Also the SSEG is placed
8076 wherever there is enough space for it, and IDATA can be anywhere
8077 in internal RAM. For now compile using -Wl-Y[stack_size].
8078 The mem file is different for this option as well, since it
8079 makes no sense of talking about DSEG lenght.
8081 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8083 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8084 in certain cases, e.g. when ROM assignment, patch provided
8085 from Albert den Haan.
8087 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8230 * src/mcs51/peephole.def,
8231 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
8232 (allows non-interrupt and interrupt code to safely compete for a resource

8326 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8328 * src/SDCCast.c (decorateType): disabled a transformation I added in
8329 revision 1.188 (access to fields of a structure at an absolute address);
8330 it breaks with bitfields, extern declarations, and gcse analysis.
8331 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8332 could be assigned through a pointer, so don't complain.
8333 * src/SDCCast.c (astErrors),
8335 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8972 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
8973 support for standard C idiom of memory mapped variables; for
8974 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8975 to xdata int at 0x1234 tempvar = 1.
8976 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8977 provided by Akiya ISHIDA

8993 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8995 Fixed bug #621531 (const & volatile confusion in the type chain).
8996 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

9088 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9089 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9090 fetching of the pointer
9091 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9092 copied from genNearPointerSet()
9093 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9094 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

9110 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9111 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9112 type for bits was changed. It resulted in bit variables becoming
9113 global, which is not permitted in PIC 14 assembly output.
9115 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9117 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9130 A few small changes that speed up the peephole optimizer.
9134 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9136 Try to make the peephole optimizer smarter by maintaining
9137 an association between the assembly source code and the
9138 iCodes that originated them. Put this information to use
9139 with a new peephole rule condition "notVolatile" so that
9140 the rules can be aggressive yet still safe.
9145 * src/mcs51/peeph.def
9147 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9151 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9152 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9153 if the left or right operand symbols have the accuse flag set.
9155 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9157 Changed the type of the result of the ! (NOT) operator to char;
9158 previously it returned the same type as the source. This allows
9159 us to eliminate all the genFloatNot functions (all of its target
9160 implementations were very buggy) since !float can use the same

9172 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9173 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9174 during interrupts. Ensure WSAVE is located at a shared bank address.
9175 2. Fixed page selection in some places
9176 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9177 the registers name strings.
9178 4. Fixed "signed / unsigned compare" compiler warnings.
9179 5. The PIC port manages its own allocation of the general purpose
9180 registers, but makes no attempt to reuse them. As a result when
9181 compiling it soon runs out of general purpose registers. Some
9182 additional code was added to the files pcode.c and device.c to walk
9183 through the function call tree and rename the registers so that they
9193 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9194 genPlus() & genMinus() when the result is the same as left or right

9200 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9202 Made bitfield a distinct type from bit so that bitfields
9203 convert as per ANSI C and bits retain their traditional
9204 boolean style behaviour. Implemented bitfield support in
9212 * src/ds390/gen.c: bit v bitfield split
9213 * src/z80/gen.c: New support for bitfields
9214 * support/regression/tests/bitfields.c: reenabled z80,
9217 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9219 Rules 246.x, 247.x relate to bitfields, the others speed up
9220 access to xdata mapped I/O devices.
9222 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9224 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9226 Cleaned up genPackBits and genUnpackBits and added two helper
9227 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9228 for literal assignments in genPackBits (thanks to Frieder for
9234 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9236 Fixed bug #748310 (pointer to function type mishandled when the
9237 function name is omitted). Also fixed a SIGSEGV when a function
9238 attribute (reentrant, etc) is used on a non-function or on a
9239 function but misplaced before the parameter list.
9241 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9243 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9244 * support/Util/SDCCerr.h,

9266 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9268 Made the constant following the "interrupt" keyword optional. If
9269 omitted, the function will not automatically be given an entry
9270 in the interrupt vector table (similar to #pragma NOIV, but
9271 less syntacticly kludgy). The interrupt number is also now
9272 range checked. Also fixed a bug in the high order bit example

9286 * src/SDCCicode.c (operandOperation): rewritten some ops
9287 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9288 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9290 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9291 be re-activated by defining REDUCE_LITERALS)
9292 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9293 unsigned, but are signed by default
9294 * src/SDCCval.c (constVal): rearranged
9295 * src/SDCCval.c (valMod): preliminary fix
9296 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9338 constants are unsigned; added recognition of "u" flag for unsigned
9339 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9340 * src/SDCCval.c (valDiv, valMod): fixed signdness

9803 messages from optionsTable when a port is not configured, added
9804 support for the PIc16 port in the ports table, when executing
9805 the compiler with no port specified on command line, a default
9806 port is selected with the new macro DEFAULT_PORT which is
9807 defined in port.h, in setDefaultOptions() linkOptions is removed
9808 from initialization assignment, since now it is a set,
9809 parseCmdLine uses setParseWithComma for linkOptions, in
9810 linkEdit() linkOptions are accessed with new function indexSet()
9811 which returns the i'th item of a set variable. See SDCCset.c, in
9812 linkEdit() when calling buildCmdLine(), added linkOptions as
9813 last argument. Now users can pass arguments to gplink via the
9814 -Wl option, main() uses pic16glue() to glue up pic16 programs

9828 gpasm complaining and test the linkage with gplink, _linkCmd and
9829 _asmCmd changed to be more gplink and gpasm friendly
9830 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9831 produced an error when parsed, peep rule 12 is added to utilize
9832 movff, but it is commented out since the pCode does not support
9833 yet a command with 2 address arguments
9835 2003-05-18 <johan AT balder>
9837 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9864 2003-05-11 Borut Razem <borut.razem AT siol.net>
9866 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

10872 * src/SDCCicode.c: fixed array add
10874 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
10875 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
10876 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
10878 2003-01-04 <johan AT balder>

10892 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10893 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10895 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10896 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10898 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10900 * in /sdcc/as/mcs51/ changed these files in order to create an
10901 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10902 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10903 following files to include the previous two files: aslink.dsp,
10904 Makefile.aslink, Makefile.bcc, and Makefile.in.
10906 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
10907 .adb instead of .cdb
10909 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10911 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
10912 value from option --iram-size.
10914 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10916 * /sdcc/as/mcs51/lklist.c: added boundary check before using
10919 2002-09-18 <wiml AT hhhh.org>
10921 * SDCClrange.h: exposed setFromRange() and setToRange()
10922 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10923 packRegsForAccUse() (bug 542397)
10924 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10925 multiple times and emitting the fetch operations more than once
10926 added aopGetUsesAcc() function to allow binary operators to
10927 fetch their operands in the correct order; made genMinus() emit
10928 compact code for X = LITERAL - Y
10930 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10931 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
10932 sprintf() in line 1267.
10934 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10935 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10938 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10939 Changes to aslink (All the changes are marked with 'JCF'):
10941 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
10944 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
10945 area BSEG. Also moves, if possible, the DATA area down into the internal
10946 ram so more space is available.
10948 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
10951 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
10952 not bytes. Function summary() which creates a memory usage summary
10953 file with extension .mem. Reports of overlaping stack and small stack
10954 size. If the space for the stack is less than 16 bytes aslink trows a
10957 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
10958 the 8051. Option 'y' for memory summary output file.
10960 Changes to sdcc (All the changes are marked with 'JCF'):
10962 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
10964 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
10965 overlaying area for it (uses RegBankUsed[4]).
10967 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
10968 bank zero as used by default. By default aslink locates the stack
10969 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10970 the creation of the .mem file. Delegates the allocation of data area
10971 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10972 the begining of the stack area to aslink.
10974 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
10975 glue() in SDCCglue.c creates an area for it.
10977 2002-09-03 Borut Razem <borut.razem AT siol.net>
10978 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10979 sdcc/src/pic/glue.c:
10980 introduced atexit() handler for teporay files removal in case of
10981 errors, assertions, ...
10983 2002-08-29 Borut Razem <borut.razem AT siol.net>
10984 * sdcc/support/cpp2/auto-host_vc_in.h:
10985 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10986 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10987 Maybe there is a similar problem with BORLANDC? It should be checked!
10989 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10990 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10991 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10992 was not executed, and the compiler (cl) launched a warning:
10993 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10995 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10996 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10998 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10999 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11001 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11002 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11003 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11004 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11005 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11006 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11007 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11008 - added Release configuration in VS projects
11009 - review of compiler an linker options
11010 - VC .exe files are generated in bin_vc directory, not to interfere
11011 with binaries generated from other projects (cygwin, mingw, bcc ...)
11013 * sdcc/src/yacc.dsp: added
11015 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11016 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11017 and insert the version number definitions from .version
11019 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11021 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11022 added - genarate auto-host.h using auto-host_vc_in.h as template
11025 removed from CVS, generated automatically
11027 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11028 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11030 2002-08-11 Borut Razem <borut.razem AT siol.net>
11031 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11033 2002-08-10 Borut Razem <borut.razem AT siol.net>
11034 * src/SDCCmain.c (main):
11035 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11036 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11037 The consequence was that some temporary files were not removed.
11040 unification of code in functions tempfilename() and tempfile():
11041 function tempnam() is defined in Visual Studio 6.0 and .NET
11043 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11045 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11046 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11047 - removed compiler command line option /WX: Treats all warnings as errors
11048 - update a list of source files, included into the project
11050 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11051 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11052 changed project type to Generic Project so that can be correcly converted to VS.NET project
11054 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11056 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11058 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11060 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11061 added return 0 statements after assert() to make compiler happy
11063 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11064 added newline in the def file to keep MSC compiler satisfied
11066 * sdcc/src/z80/gen.c:
11067 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11068 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11069 - solved MSC error in function aopDump()
11071 * sdcc_vc.h: define PREFIX as "\\sdcc"
11073 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11074 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11077 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11078 - Rewrote the register banking algorithm.
11079 - Added pCode live-range analysis to registers (for now, only non-used and
11080 singly-used registers optimized away)
11082 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11084 * 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.

11111 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11113 2002-03-28 Johan Knol <johan AT balder>
11115 * src/SDCCval.c: fixed bug #532436
11117 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11119 Added "char *Processor" field to the port structure.
11122 Added -p option. Allows port dependent processor to be specified.
11125 Initialized the new field char *Processor field to NULL in all ports
11128 Compiler generated registers for interrupt context saving
11129 were not getting allocated.
11131 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11134 Fixed left shift. Will promote the left side of a left shift
11135 if a) left shifting more than size of operand or b) when assigned
11136 to something size > size of left side
11138 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11140 tons of changes. Register allocation has been
11141 rewritten. Added customization for the various PICs. Flow
11142 analysis is restructured. ...
11144 * src/pic/device.h:
11147 * src/pic/device.c:
11148 Added. device.c is a PIC port hack to accomodate variations
11151 2002-03-13 Michael Hope <michaelh AT vroom>
11153 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11155 2002-03-04 johanknol <johanknol AT manik>
11157 * /src/SDCCval.c: fixed
11159 const unsigned char arr[][2] = { { 0, 1 } };

11246 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11248 * sdcc/src/SDCCloop.c:
11249 Previous fix was not good. basic blocks that have "break" or "return" are
11250 not really partof a loop , but live ranges used in these blocks should
