961 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
963 Enabled VPATH feature: changed nearly all Makefiles (149 files).
964 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
966 One basic decision: e.g. src/clean.mk includes further files. In order
967 to make this work there are two solutions:
968 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
969 run configure on them. This way they can use
970 'include $(srcdir)/port-clean.mk'
971 - always include clean.mk by the Makefile at the same level. To avoid
972 that `make clean` tries to include and build Makefile.dep the
973 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
974 implemented, because now even `make uninstall` doesn't create
975 Makefile.in. clean.mk could be eliminated by pasting it in
978 * debugger/mcs51/Makefile.in: build own objects from library sources
979 (SLIB, SDCC) in current directory
981 * configure, configure.in: renamed --disable-device-lib-build in
982 --disable-device-lib; added --enable-doc, the required tools are
983 searched by configure; added result message; the toolchain for the
984 belonging ports are now only built, if the port is enabled.
986 * support/regression/*: all output is written in directory gen, because
987 the fwk and ports directories don't livet in the build tree using vpath
989 * doc/sdccman.lyx: renamed --disable-device-lib-build to
990 --disable-device-lib, added --enable-doc, added section VPATH
992 * sim/ucsim/configure.in,
993 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
994 z80 are enabled by default
996 2006-04-24 Raphael Neider <rneider AT web.de>
998 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
999 to config word, "pic14_"-prefixed some extern functions
1000 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1001 config word has been found
1002 * src/pic/device.h: added prototypes
1003 * src/pic/pcode.c: added "pic14_"-prefix where needed
1004 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic

1311 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1312 call to allocReg, not by manually allocating a new one,
1313 (pic16_assignRegisters): now before going through the register
1314 allocating functions mark all registers as free. This eliminates some
1315 side effects resulting from peephole parser done earlier in the backbone

1365 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
1367 2006-03-06 Borut Razem <borut.razem AT siol.net>
1369 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1370 made the linker quiet
1372 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1374 * src/pic16/gen.c (genPcall): fixed bug #1443644
1375 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1376 which dumps before the function entry point a data byte which represents
1377 the number of the local variables used by the specified function, added
1378 'xinst' for initial support for Extended Instruction Support,
1379 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1380 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1381 port->fun_prefix anymore (may change later),
1382 (genFunction, genEndFunction): do not store/restore local registers for
1383 _main (this should take care the --main-return command line option in
1385 (genOr): removed some legacy pic-port instructions,
1386 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1387 performing operations with SFR's causes data to be written more than

1389 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1391 * src/pic16/main.c (_process_pragma): stack bound checking did not take

1394 --extended or -y for Extended Instruction Support,
1395 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1396 (deassignLRs): *** perhaps the most important change, old 'for' code
1397 (commented out for reference), didn't account for some registers which
1398 were left marked 'not free' after a pointer operation. The change
1399 reduces register usage a lot in some cases

3672 * src/SDCCglobal.h (struct options),
3674 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3675 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3676 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3677 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3678 always available in leading double underscore form. The C99 support is
3679 mostly missing, but it's a start.
3680 * support/regression/tests/bug-227710.c: fixed nonconforming use of

3759 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3761 * device/lib/printf_large.c: removed inline assembly for portability and
3762 readability. Use printf_fast if speed or size are more important.
3763 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3764 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3766 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3768 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3769 prevent compiler warning
3771 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3773 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3774 moved to level 0 and declared as static. Also they are explicit
3775 placed in access bank. This was necessery because some times they
3776 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3777 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3778 optimizations. Currently only compare to unsigned char is implemented,
3779 * src/pic16/gen.c: added fReturnIdx array,
3780 * (struct resolvedIfx) is moved to gen.h and made public,
3781 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3782 * (aopForSym): added an optimization to directly store in stack of
3783 the operand of a SEND iCode,
3784 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3785 but as registers instead (AOP_REG) using the fReturnIdx array,
3786 * (pic16_freeAsmop): remove the freed register from the
3787 _G.sregsAlloc field,
3788 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3789 a compare of 'WREG',
3790 * (pic16_popGetTempRegCond): changed function prototype, now
3791 function takes also a bitVector argument v which holds the current
3792 set of registers that are allocated for stack access by aopForSym,
3793 registers allocated in aopForSym for accessing stack symbols are not
3794 any more part of the functions usedRegs field,
3795 * (genCall): some times aopOp is called for a stack variable to be
3796 send, aopForSym might perform the push, if this is true make sure
3797 that genCall doesn't push the variable twice by testing _G.resDirect,
3798 * (genFunction): changed testing for unspecified interrupt number
3799 from 256 to INTNO_UNSPEC,
3800 * modified selection scheme of frame pointer generation. Previously
3801 if function did use local registers a frame pointer was generated,
3802 now a frame pointer is generated only if function has arguments
3803 (that need PLUSW2 register access), or has stack arguments, or the
3804 compiler is not instructed to omit the frame pointer,
3805 * (genEndFunction): before restoring local registers that were saved
3806 in the function preamble, also restore the registers that *might*
3807 have been allocated for stack access,
3808 * (genRet): removed some old comments,
3809 * (genCmp, the active (RN's) version): added a call to the
3810 pic16_genCmp_special function to perform the compare with a more
3811 robust and optimized way,
3812 * (genInline): a feature has been added in inline code generation,
3813 which allows a wildcard variable substitution when writing inline
3814 assembly. Code is incomplete and experimental therefore undocumented,
3815 * (genCast): changed order of aopOp for result and right to allow
3816 aopForSym to directly load the result if possible,
3817 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3818 perform an optimized compare on some selected special occasions,
3819 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3820 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3821 generate an IVT any more,
3822 * src/pic16/main.c (pic16_optionsTable): added command line option
3824 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3825 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3827 * src/pic16/NOTES: Raphael Neider added in list of active developers
3828 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3829 jumptable_end to prevent bug #,
3830 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3831 inCond and outCond fields,
3832 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3833 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3834 turn off register spilling,
3835 * (packRegsForOneUse): synced with other ports' versions although it
3836 is not used currently,
3837 * (pic16_packRegisters): added an optimization while reading
3838 structure bitfields, some registers may be saved (malloc code is
3839 decreased by 80 bytes)
3841 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3843 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3844 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3845 this can be optimized more?
3847 2005-03-10 Raphael Neider <rneider AT web.de>
3849 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3850 genNearPointerGet): (hopefully) fixed access to bitfields via
3851 pointers (p->bitN = x; and x = p->bitN; failed)
3853 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
3855 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

3867 * support/regression/tests/critical.c: check bug 1144613
3869 2005-03-02 Raphael Neider <rneider AT web.de>

4485 Adding support for replacing ljmps with sjmps in jumptables
4486 generated for switch statements. For now you need to set the
4487 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4488 Now 4 algorithms for mcs51 jumptable generation are used:
4489 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4490 addresses loaded pc-relative for up to 112 cases and stack-pushing
4491 target addresses loaded with offset from dptr for up to 256 cases.

4521 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4523 * added libc directory. The current version of LibC contains string
4524 functions, ctype functions and macros and some functions of the
4525 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4526 be extensively tested in the future. Standard disclaimer here.
4527 Library is not automatically build yet. But one can build it by
4528 invoking 'make' inside the libc directory.
4529 * added ADC library under libio. Preliminary version yet.

4538 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4539 * (pic16_storeForReturn): optimized return of 0,
4540 * (genCmp): experimental code for new genCmp which uses PIC18's
4541 special compare&skip instructions. Initial tests fail some times
4542 with variables grater than 1 byte in size, so new code is disabled,
4543 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4545 * (genCast): began a fix to optimize the casting of a bit to another
4546 bit, now assigning a bitfield to another bitfield will fail, sorry,
4547 * src/pic16/main.c: disabled the use of lr-support feature,
4548 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4554 * (isBankInstruction): modified to return 0 for no banking instruction,
4555 and 1 for banking instruction,
4556 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4557 caused stop processing pCodes after a inline assembly block,
4558 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4559 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4560 registers when it shouldn't,
4561 * src/pic16/ralloc.c (allocReg): add preliminary support for
4562 supporting a limited set of temporary registers,
4564 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4566 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4567 genDataPointerSet): ensure assignments always copy in MSB to LSB
4569 (loadRegFromAop): recognize CLRH optimization,
4570 (genFunction): optimize RECEIVE iCodes in reentrant functions
4572 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4574 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

7572 loaded with the linker search paths (-L arguments) and the libraries
7573 to be linked with the current source (-l arguments). Changes
7574 currently will affect only the pic16 port.
7575 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7576 include path the port specific paths and port specific libraries,
7577 * gplink command now contains the $3 argument,
7578 * src/pic16/device.h,
7579 * src/pic16/device.c,: structure PIC_device is made public and

7595 Documenting changes from previous commits.
7596 * configure.in (version 1.56),
7597 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7598 when generating output files to configure the pic16 library,
7599 but now I've commented it out, since gputils aren't installed in the
7600 SF compile farm, so library won't compile
7602 * device/lib/Makefile.in (version 1.56): initially I've added in
7603 target 'all' the prerequestive 'model-pic16' so it compiled the
7604 pic16 library, but now I've commented it out for the same reasons
7606 * added targets 'model-pic16' and 'objects-pic16' to compile the
7608 * added target 'port-specific-objects-pic16' to handle the
7609 generated libraries and copy them into the build/ directory
7610 * added target 'clean-intermediate-pic16' to clean intermediate
7611 files into pic16 directory
7612 * in target 'installdirs' added line to create directory pic16 in

7616 added lines to copy all header files to installation path,
7617 * in target 'installdirs' added line create directory for pic16
7618 headers in the installation path

7900 * src/ds390/gen.c (genRightShift): fixed bug #870788
7901 * src/SDCCast.c (decorateType): fixed bug #870781
7903 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7905 PIC16 port related changes:
7906 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7907 added variable stackPos,
7909 * gen.c: genCall, assignResultValue: added support for
7910 pushing/retrieving function parameters to/from stack,
7911 genFunction,genEndFunction: setup stack frame for the
7913 genAddrOf: will be changed according to bug 863624
7915 * added files genutils.c and genutils.h which contain gen*
7916 debugged and optimised functions extracted from gen.c
7918 * glue.c: added variable 'externs' which holds extern symbols,
7919 pic16emitRegularMap: is modified to properly handle relocatable
7920 symbols under the new scheme,
7921 pic16createInterruptVect: is modified
7922 pic16printPublics: is modified to emit 'global' assembler directives,
7923 added pic16_printExterns to print extern symbols,
7924 pic16glue: initializes stack/frame pointer in the beginning of
7925 the assembly output. Temporary hack, will be corrected later,
7926 because gplink yet does not support stack and SDCC does not
7927 yet support a type of crt0.o object to create the final binary.
7929 * Removed many lines that contain 8051 legacy code.
7930 * The code is finally placed under a 'code' directive.
7931 * Added port specific options.
7933 * _process_pragma: simplified since now we do not need *special*
7934 include file to define SFR registers. But a separate header
7935 will be needed. This will be developed later.
7936 * _pic16_parseOptions: added, parses port specific options:
7937 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7938 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7939 --preplace-udata-with=
7941 * _pic16_setDefaultOptions: modified to initialize section names,
7942 but hack is temporarly out of order since it needs improvement.
7943 * _pic16_genAssemblerPreamble: configuration words are emitted by
7944 their address instead of their name. This part is incomplete and
7945 supports only the 18Fxx2 devices. Other devices will emit an error
7946 during assembly since they do not contain the same set of config
7948 * _pic16_genIVT: is modified,
7950 * pcode.c: added definitions for some hardware registers that are needed
7952 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7953 All PCI entries are updated. Now LFSR is supported.
7954 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7955 * added pic16_newpCodeOpLit2 to support instructions with
7956 two literal arguments
7957 * pic16_pCode2str: corrected code that emits assembler instructions
7958 with two literal operands and those that have an access bit modifier
7959 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7960 this fixes a bug which caused some labels to be lost, when an
7961 assembler directive was added, i.e. banksel,
7962 * pic16_FixRegisterBanking: improved logic that causes the insertion
7964 * InlineFunction: functions that are called once, are not any more
7965 inlined. This can be a port option in the future,
7967 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7969 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7970 hold the corresponding uninitialized symbols,
7971 * pic16_allocProcessorRegister: registers have explicit marked the
7973 * pic16_allocInternalRegister: registers are explicit marked as
7975 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7976 processing list, so bit registers were lost,
7979 * ralloc.h: added field 'accessBank' and original symbol operand
7980 in register definition,
7981 * removed the field isMapped from register definition,
7983 ** Several functions have been removed from various sources:
7984 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7985 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7986 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7987 pic16_assignRelocatableRegisters
7989 ** others have been introduced:
7990 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7991 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7993 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7995 * support/scripts/inc2h.pl: changed definition of BIT_AT
7996 to emit 'sbit at' instead of 'bit at'. This was a request.
7998 PIC16 port related preliminary changes:
7999 * gen.c: prefixed function popRegFromString with
8000 pic16_ and all references to it corrected
8001 * pcode.c: all pic16_pc_* hardware registers prefixed
8002 with underscore (_),
8003 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8004 * ralloc.c: newReg(): when register is REG_SFR then
8005 set address to rIdx,
8006 pic16_allocProcessorRegister(): marks register wasUsed=0
8007 pic16_writeUsedRegs(): added a call to assign processor
8008 registers via pic16_assignFixedRegisters
8010 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8012 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8013 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8014 variables in unused register banks. Also the SSEG is placed
8015 wherever there is enough space for it, and IDATA can be anywhere
8016 in internal RAM. For now compile using -Wl-Y[stack_size].
8017 The mem file is different for this option as well, since it
8018 makes no sense of talking about DSEG lenght.
8020 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8022 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8023 in certain cases, e.g. when ROM assignment, patch provided
8024 from Albert den Haan.
8026 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8265 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8267 * src/SDCCast.c (decorateType): disabled a transformation I added in
8268 revision 1.188 (access to fields of a structure at an absolute address);
8269 it breaks with bitfields, extern declarations, and gcse analysis.
8270 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8271 could be assigned through a pointer, so don't complain.
8272 * src/SDCCast.c (astErrors),
8274 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8912 support for standard C idiom of memory mapped variables; for
8913 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8914 to xdata int at 0x1234 tempvar = 1.
8915 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8916 provided by Akiya ISHIDA

8932 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8934 Fixed bug #621531 (const & volatile confusion in the type chain).
8935 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
8936 refer to the const or volatile state of the pointer itself.

9027 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9028 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9029 fetching of the pointer
9030 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9031 copied from genNearPointerSet()
9032 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9033 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

9049 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9050 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9051 type for bits was changed. It resulted in bit variables becoming
9052 global, which is not permitted in PIC 14 assembly output.
9054 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9056 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9069 A few small changes that speed up the peephole optimizer.
9073 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9075 Try to make the peephole optimizer smarter by maintaining
9076 an association between the assembly source code and the
9077 iCodes that originated them. Put this information to use
9078 with a new peephole rule condition "notVolatile" so that
9079 the rules can be aggressive yet still safe.
9084 * src/mcs51/peeph.def
9086 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9090 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9091 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9092 if the left or right operand symbols have the accuse flag set.
9094 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9096 Changed the type of the result of the ! (NOT) operator to char;
9097 previously it returned the same type as the source. This allows
9098 us to eliminate all the genFloatNot functions (all of its target
9099 implementations were very buggy) since !float can use the same
9102 * src/SDCCicode.c (ast2iCode): ! returns char

9111 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9112 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9113 during interrupts. Ensure WSAVE is located at a shared bank address.
9114 2. Fixed page selection in some places
9115 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9116 the registers name strings.
9117 4. Fixed "signed / unsigned compare" compiler warnings.
9118 5. The PIC port manages its own allocation of the general purpose
9119 registers, but makes no attempt to reuse them. As a result when
9120 compiling it soon runs out of general purpose registers. Some
9121 additional code was added to the files pcode.c and device.c to walk
9122 through the function call tree and rename the registers so that they
9132 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9133 genPlus() & genMinus() when the result is the same as left or right

9139 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9141 Made bitfield a distinct type from bit so that bitfields
9142 convert as per ANSI C and bits retain their traditional
9143 boolean style behaviour. Implemented bitfield support in
9151 * src/ds390/gen.c: bit v bitfield split
9152 * src/z80/gen.c: New support for bitfields
9153 * support/regression/tests/bitfields.c: reenabled z80,
9156 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9158 Rules 246.x, 247.x relate to bitfields, the others speed up
9159 access to xdata mapped I/O devices.
9161 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9163 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9165 Cleaned up genPackBits and genUnpackBits and added two helper
9166 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9167 for literal assignments in genPackBits (thanks to Frieder for
9173 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9175 Fixed bug #748310 (pointer to function type mishandled when the
9176 function name is omitted). Also fixed a SIGSEGV when a function
9177 attribute (reentrant, etc) is used on a non-function or on a
9178 function but misplaced before the parameter list.
9180 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9182 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9183 * support/Util/SDCCerr.h,
9184 * support/Util/SDCCerr.c: Added func attr misuse error msg

9205 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9207 Made the constant following the "interrupt" keyword optional. If
9208 omitted, the function will not automatically be given an entry
9209 in the interrupt vector table (similar to #pragma NOIV, but
9210 less syntacticly kludgy). The interrupt number is also now
9211 range checked. Also fixed a bug in the high order bit example

9225 * src/SDCCicode.c (operandOperation): rewritten some ops
9226 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9227 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9229 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9230 be re-activated by defining REDUCE_LITERALS)
9231 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9232 unsigned, but are signed by default
9233 * src/SDCCval.c (constVal): rearranged
9234 * src/SDCCval.c (valMod): preliminary fix
9235 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9277 constants are unsigned; added recognition of "u" flag for unsigned
9278 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9279 * src/SDCCval.c (valDiv, valMod): fixed signdness
9280 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9281 signedness of modulo, left and right shift

9740 * src/SDCCmain.c: linkOptions is changed to set *,
9741 added if/endif conditional macros to remove options help
9742 messages from optionsTable when a port is not configured, added
9743 support for the PIc16 port in the ports table, when executing
9744 the compiler with no port specified on command line, a default
9745 port is selected with the new macro DEFAULT_PORT which is
9746 defined in port.h, in setDefaultOptions() linkOptions is removed
9747 from initialization assignment, since now it is a set,
9748 parseCmdLine uses setParseWithComma for linkOptions, in
9749 linkEdit() linkOptions are accessed with new function indexSet()
9750 which returns the i'th item of a set variable. See SDCCset.c, in
9751 linkEdit() when calling buildCmdLine(), added linkOptions as
9752 last argument. Now users can pass arguments to gplink via the
9753 -Wl option, main() uses pic16glue() to glue up pic16 programs

9767 gpasm complaining and test the linkage with gplink, _linkCmd and
9768 _asmCmd changed to be more gplink and gpasm friendly
9769 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9770 produced an error when parsed, peep rule 12 is added to utilize
9771 movff, but it is commented out since the pCode does not support
9772 yet a command with 2 address arguments
9774 2003-05-18 <johan AT balder>
9776 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9803 2003-05-11 Borut Razem <borut.razem AT siol.net>
9805 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9806 the path of bin directory, so that PATH is the only env. variable, which has to be set

10796 * src/SDCCast.c (decorateType): fixed bug #600035
10798 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
10799 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
10800 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
10801 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings
10802 * src/pic/pcode.c: outcommented unused variable to remove warnings

10809 2003-01-06 <johan AT balder>
10811 * src/SDCCicode.c: fixed array add
10813 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
10814 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
10815 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
10817 2003-01-04 <johan AT balder>
10819 * src/SDCCval.c (getNelements): fixed the initialized array of structures
10821 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10822 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
10824 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10825 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
10826 * support/regression/tests/bug-524697.c: fit mem usage into 8032
10828 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10829 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
10831 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10832 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10834 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10835 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10837 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10839 * in /sdcc/as/mcs51/ changed these files in order to create an
10840 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10841 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10842 following files to include the previous two files: aslink.dsp,
10843 Makefile.aslink, Makefile.bcc, and Makefile.in.
10845 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
10846 .adb instead of .cdb
10848 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10850 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
10851 value from option --iram-size.
10853 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10855 * /sdcc/as/mcs51/lklist.c: added boundary check before using
10858 2002-09-18 <wiml AT hhhh.org>
10860 * SDCClrange.h: exposed setFromRange() and setToRange()
10861 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10862 packRegsForAccUse() (bug 542397)
10863 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10864 multiple times and emitting the fetch operations more than once
10865 added aopGetUsesAcc() function to allow binary operators to
10866 fetch their operands in the correct order; made genMinus() emit
10867 compact code for X = LITERAL - Y
10869 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10870 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
10871 sprintf() in line 1267.
10873 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10874 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10877 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10878 Changes to aslink (All the changes are marked with 'JCF'):
10880 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
10883 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
10884 area BSEG. Also moves, if possible, the DATA area down into the internal
10885 ram so more space is available.
10887 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
10890 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
10891 not bytes. Function summary() which creates a memory usage summary
10892 file with extension .mem. Reports of overlaping stack and small stack
10893 size. If the space for the stack is less than 16 bytes aslink trows a
10896 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
10897 the 8051. Option 'y' for memory summary output file.
10899 Changes to sdcc (All the changes are marked with 'JCF'):
10901 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
10903 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
10904 overlaying area for it (uses RegBankUsed[4]).
10906 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
10907 bank zero as used by default. By default aslink locates the stack
10908 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10909 the creation of the .mem file. Delegates the allocation of data area
10910 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10911 the begining of the stack area to aslink.
10913 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
10914 glue() in SDCCglue.c creates an area for it.
10916 2002-09-03 Borut Razem <borut.razem AT siol.net>
10917 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10918 sdcc/src/pic/glue.c:
10919 introduced atexit() handler for teporay files removal in case of
10920 errors, assertions, ...
10922 2002-08-29 Borut Razem <borut.razem AT siol.net>
10923 * sdcc/support/cpp2/auto-host_vc_in.h:
10924 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10925 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10926 Maybe there is a similar problem with BORLANDC? It should be checked!
10928 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10929 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10930 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10931 was not executed, and the compiler (cl) launched a warning:
10932 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10934 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10935 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10937 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10938 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10940 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10941 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10942 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10943 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10944 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10945 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10946 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10947 - added Release configuration in VS projects
10948 - review of compiler an linker options
10949 - VC .exe files are generated in bin_vc directory, not to interfere
10950 with binaries generated from other projects (cygwin, mingw, bcc ...)
10952 * sdcc/src/yacc.dsp: added
10954 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10955 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10956 and insert the version number definitions from .version
10958 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10960 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10961 added - genarate auto-host.h using auto-host_vc_in.h as template
10964 removed from CVS, generated automatically
10966 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10967 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10969 2002-08-11 Borut Razem <borut.razem AT siol.net>
10970 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10972 2002-08-10 Borut Razem <borut.razem AT siol.net>
10973 * src/SDCCmain.c (main):
10974 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10975 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10976 The consequence was that some temporary files were not removed.
10979 unification of code in functions tempfilename() and tempfile():
10980 function tempnam() is defined in Visual Studio 6.0 and .NET
10982 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10984 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10985 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10986 - removed compiler command line option /WX: Treats all warnings as errors
10987 - update a list of source files, included into the project
10989 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10990 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10991 changed project type to Generic Project so that can be correcly converted to VS.NET project
10993 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10995 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10997 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10999 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11000 added return 0 statements after assert() to make compiler happy
11002 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11003 added newline in the def file to keep MSC compiler satisfied
11005 * sdcc/src/z80/gen.c:
11006 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11007 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11008 - solved MSC error in function aopDump()
11010 * sdcc_vc.h: define PREFIX as "\\sdcc"
11012 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11013 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11016 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11017 - Rewrote the register banking algorithm.
11018 - Added pCode live-range analysis to registers (for now, only non-used and
11019 singly-used registers optimized away)
11021 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11023 * 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.

11046 * src/z80/main.c: Added force callee saves for jaune.
11048 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11050 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11052 2002-03-28 Johan Knol <johan AT balder>
11054 * src/SDCCval.c: fixed bug #532436
11056 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11058 Added "char *Processor" field to the port structure.
11061 Added -p option. Allows port dependent processor to be specified.
11064 Initialized the new field char *Processor field to NULL in all ports
11067 Compiler generated registers for interrupt context saving
11068 were not getting allocated.
11070 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11073 Fixed left shift. Will promote the left side of a left shift
11074 if a) left shifting more than size of operand or b) when assigned
11075 to something size > size of left side
11077 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11079 tons of changes. Register allocation has been
11080 rewritten. Added customization for the various PICs. Flow
11081 analysis is restructured. ...
11083 * src/pic/device.h:
11086 * src/pic/device.c:
11087 Added. device.c is a PIC port hack to accomodate variations
11090 2002-03-13 Michael Hope <michaelh AT vroom>
11092 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11094 2002-03-04 johanknol <johanknol AT manik>
11096 * /src/SDCCval.c: fixed
11098 const unsigned char arr[][2] = { { 0, 1 } };
11099 t18.c:1: error: Initializer element is not constant

11185 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11187 * sdcc/src/SDCCloop.c:
11188 Previous fix was not good. basic blocks that have "break" or "return" are
11189 not really partof a loop , but live ranges used in these blocks should
11190 be live thru the entire loop, so set partOfLoop but don't add them to
11193 2002-02-21 <johan AT FRIJA>
11195 * src/SDCCcse.c: fixed bug #514308
11197 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
11200 Fixed BUG #519583. If a conditional block ended in a return/break
11201 statement inside a loop, it was not being considered part of the loop.
11203 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
11205 2002-02-10 Karl Bongers <karl AT turbobit.com>

11211 * device/examples/test2.c:
11212 Fix bug, "red" variable not being initialized(compiler complained).
11214 * device/examples/Makefile, examples/test3.c:
11215 Add Makefile in device/examples folder, compiles test3.c
11216 for use as a multiple module SDCDB test case.
11218 * sim/ucsim/cmd.src/cmdset.cc:
11219 Took out debug printfs in ucsim "next" command.
11221 * sim/ucsim/xa.src:
11222 Karl and Johan start ucsim XA support. Most dissassembly working,
11223 about 75% emulation done(plenty of work remaining).
11225 * sim/ucsim/z80.src:
11226 Add Z80 support to ucsim, add test-ucz80 regression test,
11227 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
11228 Notice z80 compiler fails on examples/test3.c/crc code.
11230 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
11232 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:

11240 from a memory mapped port
11241 2) added __builtin_memcmp
11242 3) added __builtin_swapw swap bytes of a short
11244 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
11245 1) handle multiple send & receives from register bank1
11246 2) ralloc can now allocate DPTR1 to some liveRanges
11248 * src/SDCCsymt.c, src/SDCCsymt.h:
11249 changes to handle multiple sends & receives
11251 * src/SDCCptropt.h:
11252 added some pointer arithmetic optimization
11254 * src/SDCCptropt.c:
11255 added some pointer arithmetic optimizations but not stable yet so not
11256 called from anywhere (will get this working shortly)
