1032 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1033 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1035 One basic decision: e.g. src/clean.mk includes further files. In order
1036 to make this work there are two solutions:
1037 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1038 run configure on them. This way they can use
1039 'include $(srcdir)/port-clean.mk'
1040 - always include clean.mk by the Makefile at the same level. To avoid
1041 that `make clean` tries to include and build Makefile.dep the
1042 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1043 implemented, because now even `make uninstall` doesn't create
1044 Makefile.in. clean.mk could be eliminated by pasting it in
1047 * debugger/mcs51/Makefile.in: build own objects from library sources
1048 (SLIB, SDCC) in current directory
1050 * configure, configure.in: renamed --disable-device-lib-build in
1051 --disable-device-lib; added --enable-doc, the required tools are
1052 searched by configure; added result message; the toolchain for the
1053 belonging ports are now only built, if the port is enabled.
1055 * support/regression/*: all output is written in directory gen, because
1056 the fwk and ports directories don't livet in the build tree using vpath
1058 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1059 --disable-device-lib, added --enable-doc, added section VPATH
1061 * sim/ucsim/configure.in,
1062 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1063 z80 are enabled by default
1065 2006-04-24 Raphael Neider <rneider AT web.de>
1067 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1068 to config word, "pic14_"-prefixed some extern functions
1069 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1070 config word has been found
1071 * src/pic/device.h: added prototypes
1072 * src/pic/pcode.c: added "pic14_"-prefix where needed
1073 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1075 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1090 (pCodeRegOptimizeRegUsage): fixed typo in comment

1365 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1366 allocate asmop as AOP_ACC,
1367 (aopForRemat): added parameter 'bool result' in function declaration,
1368 (pic16_aopGet): return AOP_ACC when accessing WREG,
1369 (pic16_popGetTempReg): minor modification,
1370 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1371 'pic16_allocWithIdx',

1380 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1381 call to allocReg, not by manually allocating a new one,
1382 (pic16_assignRegisters): now before going through the register
1383 allocating functions mark all registers as free. This eliminates some
1384 side effects resulting from peephole parser done earlier in the backbone

1434 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
1436 2006-03-06 Borut Razem <borut.razem AT siol.net>
1438 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1439 made the linker quiet
1441 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1443 * src/pic16/gen.c (genPcall): fixed bug #1443644
1444 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1445 which dumps before the function entry point a data byte which represents
1446 the number of the local variables used by the specified function, added
1447 'xinst' for initial support for Extended Instruction Support,
1448 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1449 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1450 port->fun_prefix anymore (may change later),
1451 (genFunction, genEndFunction): do not store/restore local registers for
1452 _main (this should take care the --main-return command line option in
1454 (genOr): removed some legacy pic-port instructions,
1455 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1456 performing operations with SFR's causes data to be written more than
1457 once to each SFR. Perhaps SFRs should be handled in special cases...
1458 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to

1463 --extended or -y for Extended Instruction Support,
1464 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1465 (deassignLRs): *** perhaps the most important change, old 'for' code
1466 (commented out for reference), didn't account for some registers which
1467 were left marked 'not free' after a pointer operation. The change
1468 reduces register usage a lot in some cases

3826 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3828 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3830 * device/lib/printf_large.c: removed inline assembly for portability and
3831 readability. Use printf_fast if speed or size are more important.
3832 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3833 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3835 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3837 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3838 prevent compiler warning
3840 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3842 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3843 moved to level 0 and declared as static. Also they are explicit
3844 placed in access bank. This was necessery because some times they
3845 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3846 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3847 optimizations. Currently only compare to unsigned char is implemented,
3848 * src/pic16/gen.c: added fReturnIdx array,
3849 * (struct resolvedIfx) is moved to gen.h and made public,
3850 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3851 * (aopForSym): added an optimization to directly store in stack of
3852 the operand of a SEND iCode,
3853 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3854 but as registers instead (AOP_REG) using the fReturnIdx array,
3855 * (pic16_freeAsmop): remove the freed register from the
3856 _G.sregsAlloc field,
3857 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3858 a compare of 'WREG',
3859 * (pic16_popGetTempRegCond): changed function prototype, now
3860 function takes also a bitVector argument v which holds the current
3861 set of registers that are allocated for stack access by aopForSym,
3862 registers allocated in aopForSym for accessing stack symbols are not
3863 any more part of the functions usedRegs field,
3864 * (genCall): some times aopOp is called for a stack variable to be
3865 send, aopForSym might perform the push, if this is true make sure
3866 that genCall doesn't push the variable twice by testing _G.resDirect,
3867 * (genFunction): changed testing for unspecified interrupt number
3868 from 256 to INTNO_UNSPEC,
3869 * modified selection scheme of frame pointer generation. Previously
3870 if function did use local registers a frame pointer was generated,
3871 now a frame pointer is generated only if function has arguments
3872 (that need PLUSW2 register access), or has stack arguments, or the
3873 compiler is not instructed to omit the frame pointer,
3874 * (genEndFunction): before restoring local registers that were saved
3875 in the function preamble, also restore the registers that *might*
3876 have been allocated for stack access,
3877 * (genRet): removed some old comments,
3878 * (genCmp, the active (RN's) version): added a call to the
3879 pic16_genCmp_special function to perform the compare with a more
3880 robust and optimized way,
3881 * (genInline): a feature has been added in inline code generation,
3882 which allows a wildcard variable substitution when writing inline
3883 assembly. Code is incomplete and experimental therefore undocumented,
3884 * (genCast): changed order of aopOp for result and right to allow
3885 aopForSym to directly load the result if possible,
3886 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3887 perform an optimized compare on some selected special occasions,
3888 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3889 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3890 generate an IVT any more,

4554 Adding support for replacing ljmps with sjmps in jumptables
4555 generated for switch statements. For now you need to set the
4556 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4557 Now 4 algorithms for mcs51 jumptable generation are used:
4558 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4559 addresses loaded pc-relative for up to 112 cases and stack-pushing
4560 target addresses loaded with offset from dptr for up to 256 cases.

4590 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4592 * added libc directory. The current version of LibC contains string
4593 functions, ctype functions and macros and some functions of the
4594 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4595 be extensively tested in the future. Standard disclaimer here.
4596 Library is not automatically build yet. But one can build it by
4597 invoking 'make' inside the libc directory.

4608 * (pic16_storeForReturn): optimized return of 0,
4609 * (genCmp): experimental code for new genCmp which uses PIC18's
4610 special compare&skip instructions. Initial tests fail some times
4611 with variables grater than 1 byte in size, so new code is disabled,
4612 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4614 * (genCast): began a fix to optimize the casting of a bit to another
4615 bit, now assigning a bitfield to another bitfield will fail, sorry,

4623 * (isBankInstruction): modified to return 0 for no banking instruction,
4624 and 1 for banking instruction,
4625 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4626 caused stop processing pCodes after a inline assembly block,
4627 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

4629 registers when it shouldn't,
4630 * src/pic16/ralloc.c (allocReg): add preliminary support for
4631 supporting a limited set of temporary registers,
4633 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4639 (genFunction): optimize RECEIVE iCodes in reentrant functions
4641 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7641 loaded with the linker search paths (-L arguments) and the libraries
7642 to be linked with the current source (-l arguments). Changes
7643 currently will affect only the pic16 port.
7644 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7645 include path the port specific paths and port specific libraries,
7646 * gplink command now contains the $3 argument,
7647 * src/pic16/device.h,
7648 * src/pic16/device.c,: structure PIC_device is made public and

7664 Documenting changes from previous commits.
7665 * configure.in (version 1.56),
7666 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7667 when generating output files to configure the pic16 library,
7668 but now I've commented it out, since gputils aren't installed in the
7669 SF compile farm, so library won't compile
7671 * device/lib/Makefile.in (version 1.56): initially I've added in
7672 target 'all' the prerequestive 'model-pic16' so it compiled the
7673 pic16 library, but now I've commented it out for the same reasons
7675 * added targets 'model-pic16' and 'objects-pic16' to compile the
7677 * added target 'port-specific-objects-pic16' to handle the
7678 generated libraries and copy them into the build/ directory
7679 * added target 'clean-intermediate-pic16' to clean intermediate
7680 files into pic16 directory
7681 * in target 'installdirs' added line to create directory pic16 in

7685 added lines to copy all header files to installation path,
7686 * in target 'installdirs' added line create directory for pic16
7687 headers in the installation path

7926 * src/SDCCast.c (decorateType),
7927 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
7928 LEFT_OP (left shift)
7930 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7932 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7933 (default behaviour).
7935 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7937 A python script to validate compiler diagnostic messages. It can be
7938 used to verify that sdcc complains about bad c source code and
7939 gives a good location of the error.
7940 * support/valdiag/Makefile,
7941 * support/valdiag/valdiag.py,
7942 * support/valdiag/tests/*
7944 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7955 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7957 * src/common.h: added ifndef/define/endif macros
7958 around the header file.
7959 Bug reported from Jesus Calvino-Fraga
7961 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7963 * sdcc.spec: updated
7964 * device/include/Makefile.in: don't install CVS directories
7965 * device/lib/Makefile.in: added removal of CVS directories after install
7966 * doc/Makefile: fixed install, added local_icons
7967 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7968 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7969 * src/ds390/gen.c (genRightShift): fixed bug #870788
7970 * src/SDCCast.c (decorateType): fixed bug #870781
7972 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7974 PIC16 port related changes:
7975 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7976 added variable stackPos,
7978 * gen.c: genCall, assignResultValue: added support for
7979 pushing/retrieving function parameters to/from stack,
7980 genFunction,genEndFunction: setup stack frame for the
7982 genAddrOf: will be changed according to bug 863624
7984 * added files genutils.c and genutils.h which contain gen*
7985 debugged and optimised functions extracted from gen.c
7987 * glue.c: added variable 'externs' which holds extern symbols,
7988 pic16emitRegularMap: is modified to properly handle relocatable
7989 symbols under the new scheme,
7990 pic16createInterruptVect: is modified
7991 pic16printPublics: is modified to emit 'global' assembler directives,
7992 added pic16_printExterns to print extern symbols,
7993 pic16glue: initializes stack/frame pointer in the beginning of
7994 the assembly output. Temporary hack, will be corrected later,
7995 because gplink yet does not support stack and SDCC does not
7996 yet support a type of crt0.o object to create the final binary.
7998 * Removed many lines that contain 8051 legacy code.
7999 * The code is finally placed under a 'code' directive.
8000 * Added port specific options.
8002 * _process_pragma: simplified since now we do not need *special*
8003 include file to define SFR registers. But a separate header
8004 will be needed. This will be developed later.
8005 * _pic16_parseOptions: added, parses port specific options:
8006 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8007 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8008 --preplace-udata-with=
8010 * _pic16_setDefaultOptions: modified to initialize section names,
8011 but hack is temporarly out of order since it needs improvement.
8012 * _pic16_genAssemblerPreamble: configuration words are emitted by
8013 their address instead of their name. This part is incomplete and
8014 supports only the 18Fxx2 devices. Other devices will emit an error
8015 during assembly since they do not contain the same set of config
8017 * _pic16_genIVT: is modified,
8019 * pcode.c: added definitions for some hardware registers that are needed
8021 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8022 All PCI entries are updated. Now LFSR is supported.
8023 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8024 * added pic16_newpCodeOpLit2 to support instructions with
8025 two literal arguments
8026 * pic16_pCode2str: corrected code that emits assembler instructions
8027 with two literal operands and those that have an access bit modifier
8028 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8029 this fixes a bug which caused some labels to be lost, when an
8030 assembler directive was added, i.e. banksel,
8031 * pic16_FixRegisterBanking: improved logic that causes the insertion
8033 * InlineFunction: functions that are called once, are not any more
8034 inlined. This can be a port option in the future,
8036 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8038 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8039 hold the corresponding uninitialized symbols,
8040 * pic16_allocProcessorRegister: registers have explicit marked the
8042 * pic16_allocInternalRegister: registers are explicit marked as
8044 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8045 processing list, so bit registers were lost,
8048 * ralloc.h: added field 'accessBank' and original symbol operand
8049 in register definition,
8050 * removed the field isMapped from register definition,
8052 ** Several functions have been removed from various sources:
8053 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8054 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8055 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8056 pic16_assignRelocatableRegisters
8058 ** others have been introduced:
8059 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8060 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8062 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8064 * support/scripts/inc2h.pl: changed definition of BIT_AT
8065 to emit 'sbit at' instead of 'bit at'. This was a request.
8067 PIC16 port related preliminary changes:
8068 * gen.c: prefixed function popRegFromString with
8069 pic16_ and all references to it corrected
8070 * pcode.c: all pic16_pc_* hardware registers prefixed
8071 with underscore (_),
8072 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8073 * ralloc.c: newReg(): when register is REG_SFR then
8074 set address to rIdx,
8075 pic16_allocProcessorRegister(): marks register wasUsed=0
8076 pic16_writeUsedRegs(): added a call to assign processor
8077 registers via pic16_assignFixedRegisters
8079 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8081 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8082 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8083 variables in unused register banks. Also the SSEG is placed
8084 wherever there is enough space for it, and IDATA can be anywhere
8085 in internal RAM. For now compile using -Wl-Y[stack_size].
8086 The mem file is different for this option as well, since it
8087 makes no sense of talking about DSEG lenght.
8089 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8091 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8092 in certain cases, e.g. when ROM assignment, patch provided
8093 from Albert den Haan.
8095 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8238 * src/mcs51/peephole.def,
8239 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

8334 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8336 * src/SDCCast.c (decorateType): disabled a transformation I added in
8337 revision 1.188 (access to fields of a structure at an absolute address);
8338 it breaks with bitfields, extern declarations, and gcse analysis.
8339 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8340 could be assigned through a pointer, so don't complain.
8341 * src/SDCCast.c (astErrors),
8343 * src/SDCCglue.c (emitRegularMap): fixed bug #847813
8345 2003-11-26 Vangelis Rokas <vrokas AT otenet.gr>

8351 pre-processor macro, i.e. -DMCU=p18f452
8352 * src/pic16/ralloc.c: renamed packRegisters to pic16_packRegisters,
8353 and modified to handle 'cast' icode similarly to '=' icode

8980 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
8981 support for standard C idiom of memory mapped variables; for
8982 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8983 to xdata int at 0x1234 tempvar = 1.

9001 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9003 Fixed bug #621531 (const & volatile confusion in the type chain).
9004 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

9096 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9097 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9098 fetching of the pointer
9099 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9100 copied from genNearPointerSet()
9101 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9102 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9103 If they pop r0/r1 they must be called in the opposite order than aopOp().
9104 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9105 (resp. --stack-auto), prepared for --xstack

9116 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9118 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9119 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9120 type for bits was changed. It resulted in bit variables becoming
9121 global, which is not permitted in PIC 14 assembly output.
9123 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9125 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9138 A few small changes that speed up the peephole optimizer.
9142 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9144 Try to make the peephole optimizer smarter by maintaining
9145 an association between the assembly source code and the
9146 iCodes that originated them. Put this information to use
9147 with a new peephole rule condition "notVolatile" so that
9148 the rules can be aggressive yet still safe.
9153 * src/mcs51/peeph.def
9155 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9159 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9160 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9161 if the left or right operand symbols have the accuse flag set.
9163 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9165 Changed the type of the result of the ! (NOT) operator to char;
9166 previously it returned the same type as the source. This allows
9167 us to eliminate all the genFloatNot functions (all of its target
9168 implementations were very buggy) since !float can use the same
9171 * src/SDCCicode.c (ast2iCode): ! returns char

9180 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9181 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9182 during interrupts. Ensure WSAVE is located at a shared bank address.
9183 2. Fixed page selection in some places
9184 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9185 the registers name strings.
9186 4. Fixed "signed / unsigned compare" compiler warnings.
9187 5. The PIC port manages its own allocation of the general purpose
9188 registers, but makes no attempt to reuse them. As a result when
9189 compiling it soon runs out of general purpose registers. Some
9190 additional code was added to the files pcode.c and device.c to walk
9191 through the function call tree and rename the registers so that they
9201 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9202 genPlus() & genMinus() when the result is the same as left or right

9208 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9210 Made bitfield a distinct type from bit so that bitfields
9211 convert as per ANSI C and bits retain their traditional
9212 boolean style behaviour. Implemented bitfield support in
9220 * src/ds390/gen.c: bit v bitfield split
9221 * src/z80/gen.c: New support for bitfields
9222 * support/regression/tests/bitfields.c: reenabled z80,
9225 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9227 Rules 246.x, 247.x relate to bitfields, the others speed up
9228 access to xdata mapped I/O devices.
9230 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9232 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9234 Cleaned up genPackBits and genUnpackBits and added two helper
9235 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9236 for literal assignments in genPackBits (thanks to Frieder for
9242 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9244 Fixed bug #748310 (pointer to function type mishandled when the
9245 function name is omitted). Also fixed a SIGSEGV when a function
9246 attribute (reentrant, etc) is used on a non-function or on a
9247 function but misplaced before the parameter list.
9249 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9251 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9252 * support/Util/SDCCerr.h,

9274 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9276 Made the constant following the "interrupt" keyword optional. If
9277 omitted, the function will not automatically be given an entry
9278 in the interrupt vector table (similar to #pragma NOIV, but
9279 less syntacticly kludgy). The interrupt number is also now
9280 range checked. Also fixed a bug in the high order bit example

9294 * src/SDCCicode.c (operandOperation): rewritten some ops
9295 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9296 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9298 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9299 be re-activated by defining REDUCE_LITERALS)
9300 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9301 unsigned, but are signed by default
9302 * src/SDCCval.c (constVal): rearranged
9303 * src/SDCCval.c (valMod): preliminary fix
9304 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9346 constants are unsigned; added recognition of "u" flag for unsigned
9347 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9348 * src/SDCCval.c (valDiv, valMod): fixed signdness
9349 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9350 signedness of modulo, left and right shift

9812 support for the PIc16 port in the ports table, when executing
9813 the compiler with no port specified on command line, a default
9814 port is selected with the new macro DEFAULT_PORT which is
9815 defined in port.h, in setDefaultOptions() linkOptions is removed
9816 from initialization assignment, since now it is a set,
9817 parseCmdLine uses setParseWithComma for linkOptions, in
9818 linkEdit() linkOptions are accessed with new function indexSet()
9819 which returns the i'th item of a set variable. See SDCCset.c, in
9820 linkEdit() when calling buildCmdLine(), added linkOptions as
9821 last argument. Now users can pass arguments to gplink via the

9836 gpasm complaining and test the linkage with gplink, _linkCmd and
9837 _asmCmd changed to be more gplink and gpasm friendly
9838 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9839 produced an error when parsed, peep rule 12 is added to utilize
9840 movff, but it is commented out since the pCode does not support
9841 yet a command with 2 address arguments
9843 2003-05-18 <johan AT balder>

10903 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10904 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10906 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10908 * in /sdcc/as/mcs51/ changed these files in order to create an
10909 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10910 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10911 following files to include the previous two files: aslink.dsp,
10912 Makefile.aslink, Makefile.bcc, and Makefile.in.
10914 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
10915 .adb instead of .cdb
10917 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10919 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
10920 value from option --iram-size.
10922 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10924 * /sdcc/as/mcs51/lklist.c: added boundary check before using
10927 2002-09-18 <wiml AT hhhh.org>
10929 * SDCClrange.h: exposed setFromRange() and setToRange()
10930 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10931 packRegsForAccUse() (bug 542397)
10932 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10933 multiple times and emitting the fetch operations more than once
10934 added aopGetUsesAcc() function to allow binary operators to
10935 fetch their operands in the correct order; made genMinus() emit
10936 compact code for X = LITERAL - Y
10938 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10939 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
10940 sprintf() in line 1267.
10942 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10943 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10946 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10947 Changes to aslink (All the changes are marked with 'JCF'):
10949 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
10952 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
10953 area BSEG. Also moves, if possible, the DATA area down into the internal
10954 ram so more space is available.
10956 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
10959 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
10960 not bytes. Function summary() which creates a memory usage summary
10961 file with extension .mem. Reports of overlaping stack and small stack
10962 size. If the space for the stack is less than 16 bytes aslink trows a
10965 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
10966 the 8051. Option 'y' for memory summary output file.
10968 Changes to sdcc (All the changes are marked with 'JCF'):
10970 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
10972 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
10973 overlaying area for it (uses RegBankUsed[4]).
10975 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
10976 bank zero as used by default. By default aslink locates the stack
10977 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10978 the creation of the .mem file. Delegates the allocation of data area
10979 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10980 the begining of the stack area to aslink.
10982 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
10983 glue() in SDCCglue.c creates an area for it.
10985 2002-09-03 Borut Razem <borut.razem AT siol.net>
10986 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10987 sdcc/src/pic/glue.c:
10988 introduced atexit() handler for teporay files removal in case of
10989 errors, assertions, ...
10991 2002-08-29 Borut Razem <borut.razem AT siol.net>
10992 * sdcc/support/cpp2/auto-host_vc_in.h:
10993 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10994 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10995 Maybe there is a similar problem with BORLANDC? It should be checked!
10997 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10998 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10999 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11000 was not executed, and the compiler (cl) launched a warning:
11001 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11003 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11004 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11006 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11007 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11009 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11010 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11011 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11012 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11013 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11014 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11015 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11016 - added Release configuration in VS projects
11017 - review of compiler an linker options
11018 - VC .exe files are generated in bin_vc directory, not to interfere
11019 with binaries generated from other projects (cygwin, mingw, bcc ...)
11021 * sdcc/src/yacc.dsp: added
11023 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11024 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11025 and insert the version number definitions from .version
11027 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11029 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11030 added - genarate auto-host.h using auto-host_vc_in.h as template
11033 removed from CVS, generated automatically
11035 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11036 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11038 2002-08-11 Borut Razem <borut.razem AT siol.net>
11039 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11041 2002-08-10 Borut Razem <borut.razem AT siol.net>
11042 * src/SDCCmain.c (main):
11043 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11044 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11045 The consequence was that some temporary files were not removed.
11048 unification of code in functions tempfilename() and tempfile():
11049 function tempnam() is defined in Visual Studio 6.0 and .NET
11051 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11053 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11054 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11055 - removed compiler command line option /WX: Treats all warnings as errors
11056 - update a list of source files, included into the project
11058 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11059 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11060 changed project type to Generic Project so that can be correcly converted to VS.NET project
11062 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11064 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11066 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11068 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11069 added return 0 statements after assert() to make compiler happy
11071 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11072 added newline in the def file to keep MSC compiler satisfied
11074 * sdcc/src/z80/gen.c:
11075 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11076 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11077 - solved MSC error in function aopDump()
11079 * sdcc_vc.h: define PREFIX as "\\sdcc"
11081 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

11085 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11086 - Rewrote the register banking algorithm.
11087 - Added pCode live-range analysis to registers (for now, only non-used and
11088 singly-used registers optimized away)
11090 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11092 * 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.

11130 Added -p option. Allows port dependent processor to be specified.
11133 Initialized the new field char *Processor field to NULL in all ports
11136 Compiler generated registers for interrupt context saving
11137 were not getting allocated.
11139 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11142 Fixed left shift. Will promote the left side of a left shift
11143 if a) left shifting more than size of operand or b) when assigned
11144 to something size > size of left side

11256 * sdcc/src/SDCCloop.c:
11257 Previous fix was not good. basic blocks that have "break" or "return" are
11258 not really partof a loop , but live ranges used in these blocks should
11259 be live thru the entire loop, so set partOfLoop but don't add them to
