629 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
630 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
631 always available in leading double underscore form. The C99 support is
632 mostly missing, but it's a start.
633 * support/regression/tests/bug-227710.c: fixed nonconforming use of
634 reserved identifier "__data".

712 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
714 * device/lib/printf_large.c: removed inline assembly for portability and
715 readability. Use printf_fast if speed or size are more important.
716 * src/pic16/gen.c: removed conditions around use of DEBUGpc
717 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
719 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
721 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
722 prevent compiler warning
724 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
726 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
727 moved to level 0 and declared as static. Also they are explicit
728 placed in access bank. This was necessery because some times they
729 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
730 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
731 optimizations. Currently only compare to unsigned char is implemented,
732 * src/pic16/gen.c: added fReturnIdx array,
733 * (struct resolvedIfx) is moved to gen.h and made public,
734 * (struct _G): added sregsAlloc and sregsAllocSet fields,
735 * (aopForSym): added an optimization to directly store in stack of
736 the operand of a SEND iCode,
737 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
738 but as registers instead (AOP_REG) using the fReturnIdx array,
739 * (pic16_freeAsmop): remove the freed register from the
741 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
743 * (pic16_popGetTempRegCond): changed function prototype, now
744 function takes also a bitVector argument v which holds the current
745 set of registers that are allocated for stack access by aopForSym,
746 registers allocated in aopForSym for accessing stack symbols are not
747 any more part of the functions usedRegs field,
748 * (genCall): some times aopOp is called for a stack variable to be
749 send, aopForSym might perform the push, if this is true make sure
750 that genCall doesn't push the variable twice by testing _G.resDirect,
751 * (genFunction): changed testing for unspecified interrupt number
752 from 256 to INTNO_UNSPEC,
753 * modified selection scheme of frame pointer generation. Previously
754 if function did use local registers a frame pointer was generated,
755 now a frame pointer is generated only if function has arguments
756 (that need PLUSW2 register access), or has stack arguments, or the
757 compiler is not instructed to omit the frame pointer,
758 * (genEndFunction): before restoring local registers that were saved
759 in the function preamble, also restore the registers that *might*
760 have been allocated for stack access,
761 * (genRet): removed some old comments,
762 * (genCmp, the active (RN's) version): added a call to the
763 pic16_genCmp_special function to perform the compare with a more
764 robust and optimized way,
765 * (genInline): a feature has been added in inline code generation,
766 which allows a wildcard variable substitution when writing inline
767 assembly. Code is incomplete and experimental therefore undocumented,
768 * (genCast): changed order of aopOp for result and right to allow
769 aopForSym to directly load the result if possible,
770 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
771 perform an optimized compare on some selected special occasions,
772 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
773 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
774 generate an IVT any more,
775 * src/pic16/main.c (pic16_optionsTable): added command line option
777 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
778 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
780 * src/pic16/NOTES: Raphael Neider added in list of active developers
781 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
782 jumptable_end to prevent bug #,
783 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
784 inCond and outCond fields,
785 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
786 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
787 turn off register spilling,
788 * (packRegsForOneUse): synced with other ports' versions although it
789 is not used currently,
790 * (pic16_packRegisters): added an optimization while reading
791 structure bitfields, some registers may be saved (malloc code is
792 decreased by 80 bytes)
794 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
796 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
797 left is a bitfield, if yes, then don't optimize assignment. Perhaps
798 this can be optimized more?
800 2005-03-10 Raphael Neider <rneider AT web.de>
802 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
803 genNearPointerGet): (hopefully) fixed access to bitfields via
804 pointers (p->bitN = x; and x = p->bitN; failed)
806 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
808 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

850 to keep the correct label reference count when adding/removing references
851 to labels. A peephole file using this is appended to patch #1144962.

1438 Adding support for replacing ljmps with sjmps in jumptables
1439 generated for switch statements. For now you need to set the
1440 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1441 Now 4 algorithms for mcs51 jumptable generation are used:
1442 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1443 addresses loaded pc-relative for up to 112 cases and stack-pushing
1444 target addresses loaded with offset from dptr for up to 256 cases.

1474 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1476 * added libc directory. The current version of LibC contains string
1477 functions, ctype functions and macros and some functions of the
1478 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1479 be extensively tested in the future. Standard disclaimer here.
1480 Library is not automatically build yet. But one can build it by
1481 invoking 'make' inside the libc directory.
1482 * added ADC library under libio. Preliminary version yet.

1492 * (pic16_storeForReturn): optimized return of 0,
1493 * (genCmp): experimental code for new genCmp which uses PIC18's
1494 special compare&skip instructions. Initial tests fail some times
1495 with variables grater than 1 byte in size, so new code is disabled,
1496 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1498 * (genCast): began a fix to optimize the casting of a bit to another
1499 bit, now assigning a bitfield to another bitfield will fail, sorry,
1500 * src/pic16/main.c: disabled the use of lr-support feature,
1501 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

1508 and 1 for banking instruction,
1509 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1510 caused stop processing pCodes after a inline assembly block,
1511 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

1513 registers when it shouldn't,
1514 * src/pic16/ralloc.c (allocReg): add preliminary support for
1515 supporting a limited set of temporary registers,
1517 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4434 * as/Makefile (install-doc): Made work on Mac.
4436 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
4438 * src/SDCCast.c: added an additional type flow in decorateType() of
4439 opposite direction, see feature request #860006; it's enabled at runtime
4440 by setting the environment variable SDCC_NEWTYPEFLOW
4441 * src/SDCCast.h: changed prototype of decorateType()
4442 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
4443 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
4444 'char' to 'int' can be omitted, if both operands are 'unsigned char';
4445 see feature request #877103
4446 * src/SDCCval.c: updated call of decorateType()
4447 (valBitwise): fixed bug #882876
4448 (valMinus): added promotion
4449 (valLogicAndOr): result is unsigned
4450 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
4451 * src/SDCCsymt.c (computeType),
4452 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
4453 must not cause an unsigned operation
4454 * src/pic/glue (pic14emitRegularMap),
4455 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
4457 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>

4474 * src/pic/ralloc.h: applied patch from Slade Rich;
4475 added support for multiple code pages and multiple RAM banks on the
4476 PIC 14 port. The ASM files now no longer simply assume all the
4477 code / RAM are in the same page / bank. This means the linker can
4478 safely allocate code/RAM of separate ASM files to different pages/banks.
4479 * doc/sdccman.lyx: added Slade's tips
4480 * src/mcs51/peeph.def: fixed bug #880768

4489 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
4492 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
4493 strtof is not part of C89 and isn't included with Mac OS X.
4495 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4497 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

4519 * src/ds390/gen.c (aopOp3): fixed the assignment of different dptrs to
4522 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4524 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4525 loaded with the linker search paths (-L arguments) and the libraries
4526 to be linked with the current source (-l arguments). Changes
4527 currently will affect only the pic16 port.
4528 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4529 include path the port specific paths and port specific libraries,
4530 * gplink command now contains the $3 argument,
4531 * src/pic16/device.h,
4532 * src/pic16/device.c,: structure PIC_device is made public and
4533 renamed to PIC16_device, the same for variable Pics which is renamed

4548 Documenting changes from previous commits.
4549 * configure.in (version 1.56),
4550 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4551 when generating output files to configure the pic16 library,
4552 but now I've commented it out, since gputils aren't installed in the
4553 SF compile farm, so library won't compile
4555 * device/lib/Makefile.in (version 1.56): initially I've added in
4556 target 'all' the prerequestive 'model-pic16' so it compiled the
4557 pic16 library, but now I've commented it out for the same reasons
4559 * added targets 'model-pic16' and 'objects-pic16' to compile the
4561 * added target 'port-specific-objects-pic16' to handle the
4562 generated libraries and copy them into the build/ directory
4563 * added target 'clean-intermediate-pic16' to clean intermediate
4564 files into pic16 directory
4565 * in target 'installdirs' added line to create directory pic16 in
4566 the installation path
4568 * device/include/Makefile.in (version 1.11): in target 'install'
4569 added lines to copy all header files to installation path,
4570 * in target 'installdirs' added line create directory for pic16
4571 headers in the installation path

4586 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4587 option so that it actually works. Made it specific to the z80, since
4588 the gbz80 doesn't have these kinds of I/O ports.
4590 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4592 * device/include/z180.h,

4614 Mainly changes to support compilation of the device libraries
4615 * src/pic16/device.c: stack is allocated via symbol and not
4616 via literal number. The symbol is placed in the corresponding
4617 position of the data ram
4618 * (pic16_dump_section): relocatable and absolute uninitialized
4619 data are now emitted in sorted order to reduce section naming,
4620 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4621 weren't marked as being in the access bank,
4623 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4625 Added portion of GNU PIC Library under the directory
4626 device/include/pic16 and device/lib/pic16. These files
4627 contain the declarations of SFRs for the PIC18Fxx2 devices.
4628 The directory is initialized via configure from toplevel.
4630 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4632 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

4658 all over. Telling LaTeX to be less strict with word spacing
4659 to better keep the right margin. Changed some notes about
4660 maintainance of the ports in section 3.2.1 - is it OK like this?
4662 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

4700 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4702 * src/pic16/peeph.def: all peepholes with movff are commented out,
4703 because there is a problem in the pcode peep optimizer,
4704 * src/pic16/ralloc.c: the register allocator can now reuse local

4856 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4858 PIC16 port related changes:
4859 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4860 added variable stackPos,
4862 * gen.c: genCall, assignResultValue: added support for
4863 pushing/retrieving function parameters to/from stack,
4864 genFunction,genEndFunction: setup stack frame for the
4866 genAddrOf: will be changed according to bug 863624
4868 * added files genutils.c and genutils.h which contain gen*
4869 debugged and optimised functions extracted from gen.c
4871 * glue.c: added variable 'externs' which holds extern symbols,
4872 pic16emitRegularMap: is modified to properly handle relocatable
4873 symbols under the new scheme,
4874 pic16createInterruptVect: is modified
4875 pic16printPublics: is modified to emit 'global' assembler directives,
4876 added pic16_printExterns to print extern symbols,
4877 pic16glue: initializes stack/frame pointer in the beginning of
4878 the assembly output. Temporary hack, will be corrected later,
4879 because gplink yet does not support stack and SDCC does not
4880 yet support a type of crt0.o object to create the final binary.
4882 * Removed many lines that contain 8051 legacy code.
4883 * The code is finally placed under a 'code' directive.
4884 * Added port specific options.
4886 * _process_pragma: simplified since now we do not need *special*
4887 include file to define SFR registers. But a separate header
4888 will be needed. This will be developed later.
4889 * _pic16_parseOptions: added, parses port specific options:
4890 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4891 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4892 --preplace-udata-with=
4894 * _pic16_setDefaultOptions: modified to initialize section names,
4895 but hack is temporarly out of order since it needs improvement.
4896 * _pic16_genAssemblerPreamble: configuration words are emitted by
4897 their address instead of their name. This part is incomplete and
4898 supports only the 18Fxx2 devices. Other devices will emit an error
4899 during assembly since they do not contain the same set of config
4901 * _pic16_genIVT: is modified,
4903 * pcode.c: added definitions for some hardware registers that are needed
4905 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4906 All PCI entries are updated. Now LFSR is supported.
4907 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4908 * added pic16_newpCodeOpLit2 to support instructions with
4909 two literal arguments
4910 * pic16_pCode2str: corrected code that emits assembler instructions
4911 with two literal operands and those that have an access bit modifier
4912 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4913 this fixes a bug which caused some labels to be lost, when an
4914 assembler directive was added, i.e. banksel,
4915 * pic16_FixRegisterBanking: improved logic that causes the insertion
4917 * InlineFunction: functions that are called once, are not any more
4918 inlined. This can be a port option in the future,
4920 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4922 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4923 hold the corresponding uninitialized symbols,
4924 * pic16_allocProcessorRegister: registers have explicit marked the
4926 * pic16_allocInternalRegister: registers are explicit marked as
4928 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4929 processing list, so bit registers were lost,
4932 * ralloc.h: added field 'accessBank' and original symbol operand
4933 in register definition,
4934 * removed the field isMapped from register definition,
4936 ** Several functions have been removed from various sources:
4937 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4938 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4939 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4940 pic16_assignRelocatableRegisters
4942 ** others have been introduced:
4943 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4944 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4946 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4948 * support/scripts/inc2h.pl: changed definition of BIT_AT
4949 to emit 'sbit at' instead of 'bit at'. This was a request.
4951 PIC16 port related preliminary changes:
4952 * gen.c: prefixed function popRegFromString with
4953 pic16_ and all references to it corrected
4954 * pcode.c: all pic16_pc_* hardware registers prefixed
4955 with underscore (_),
4956 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4957 * ralloc.c: newReg(): when register is REG_SFR then
4958 set address to rIdx,
4959 pic16_allocProcessorRegister(): marks register wasUsed=0
4960 pic16_writeUsedRegs(): added a call to assign processor
4961 registers via pic16_assignFixedRegisters
4963 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4965 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4966 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4967 variables in unused register banks. Also the SSEG is placed
4968 wherever there is enough space for it, and IDATA can be anywhere
4969 in internal RAM. For now compile using -Wl-Y[stack_size].
4970 The mem file is different for this option as well, since it
4971 makes no sense of talking about DSEG lenght.
4973 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4975 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4976 in certain cases, e.g. when ROM assignment, patch provided
4977 from Albert den Haan.

5220 * src/SDCCast.c (decorateType): disabled a transformation I added in
5221 revision 1.188 (access to fields of a structure at an absolute address);
5222 it breaks with bitfields, extern declarations, and gcse analysis.
5223 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
5224 could be assigned through a pointer, so don't complain.

5981 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5982 fetching of the pointer
5983 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5984 copied from genNearPointerSet()
5985 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5986 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

6000 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
6002 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6003 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6004 type for bits was changed. It resulted in bit variables becoming
6005 global, which is not permitted in PIC 14 assembly output.
6007 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6009 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6022 A few small changes that speed up the peephole optimizer.
6026 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6028 Try to make the peephole optimizer smarter by maintaining
6029 an association between the assembly source code and the
6030 iCodes that originated them. Put this information to use
6031 with a new peephole rule condition "notVolatile" so that
6032 the rules can be aggressive yet still safe.
6037 * src/mcs51/peeph.def
6039 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6043 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6044 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6045 if the left or right operand symbols have the accuse flag set.
6047 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6049 Changed the type of the result of the ! (NOT) operator to char;
6050 previously it returned the same type as the source. This allows
6051 us to eliminate all the genFloatNot functions (all of its target
6052 implementations were very buggy) since !float can use the same
6055 * src/SDCCicode.c (ast2iCode): ! returns char

6064 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6065 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6066 during interrupts. Ensure WSAVE is located at a shared bank address.
6067 2. Fixed page selection in some places
6068 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6069 the registers name strings.
6070 4. Fixed "signed / unsigned compare" compiler warnings.
6071 5. The PIC port manages its own allocation of the general purpose
6072 registers, but makes no attempt to reuse them. As a result when
6073 compiling it soon runs out of general purpose registers. Some
6074 additional code was added to the files pcode.c and device.c to walk
6075 through the function call tree and rename the registers so that they
6085 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

6092 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6094 Made bitfield a distinct type from bit so that bitfields
6095 convert as per ANSI C and bits retain their traditional
6096 boolean style behaviour. Implemented bitfield support in
6104 * src/ds390/gen.c: bit v bitfield split
6105 * src/z80/gen.c: New support for bitfields
6106 * support/regression/tests/bitfields.c: reenabled z80,
6109 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6111 Rules 246.x, 247.x relate to bitfields, the others speed up
6112 access to xdata mapped I/O devices.
6114 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6116 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6118 Cleaned up genPackBits and genUnpackBits and added two helper
6119 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6120 for literal assignments in genPackBits (thanks to Frieder for
6126 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6128 Fixed bug #748310 (pointer to function type mishandled when the
6129 function name is omitted). Also fixed a SIGSEGV when a function
6130 attribute (reentrant, etc) is used on a non-function or on a
6131 function but misplaced before the parameter list.
6133 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6135 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

6158 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6160 Made the constant following the "interrupt" keyword optional. If
6161 omitted, the function will not automatically be given an entry
6162 in the interrupt vector table (similar to #pragma NOIV, but
6163 less syntacticly kludgy). The interrupt number is also now
6164 range checked. Also fixed a bug in the high order bit example

6180 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6182 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6183 be re-activated by defining REDUCE_LITERALS)
6184 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6185 unsigned, but are signed by default
6186 * src/SDCCval.c (constVal): rearranged
6187 * src/SDCCval.c (valMod): preliminary fix
6188 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6640 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
6641 the regression tests I'm not brave enough to enable 245.b, 245.c
6642 * doc/sdccman.lyx: added latex preamble for hyperref package.
6643 Using pdflatex this will give you a hyperlinked pdf file with
6644 bookmarks. (prepend '%' before /usepackage if this breaks something)

6660 Applied patch from bug 737905 (renamed yylineo to mylineno):
6667 * src/pic16/pcode.c: Cleaned warnings
6668 * src/pic16/pcodeflow.c: Cleaned warnings

6682 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
6684 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
6685 it can be defined with CFLAGS when running configure
6686 * src/SDCCmain.c: fixed compiling + linking with object files
6688 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

6691 added --disable-pic16-port
6692 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
6693 * src/SDCCmain.c: linkOptions is changed to set *,
6694 added if/endif conditional macros to remove options help
6695 messages from optionsTable when a port is not configured, added
6696 support for the PIc16 port in the ports table, when executing
6697 the compiler with no port specified on command line, a default
6698 port is selected with the new macro DEFAULT_PORT which is
6699 defined in port.h, in setDefaultOptions() linkOptions is removed
6700 from initialization assignment, since now it is a set,
6701 parseCmdLine uses setParseWithComma for linkOptions, in
6702 linkEdit() linkOptions are accessed with new function indexSet()
6703 which returns the i'th item of a set variable. See SDCCset.c, in
6704 linkEdit() when calling buildCmdLine(), added linkOptions as
6705 last argument. Now users can pass arguments to gplink via the
6706 -Wl option, main() uses pic16glue() to glue up pic16 programs

6718 * src/pic16/glue.c: commented out some error producing lines
6719 * src/pic16/main.c: __config directives are commented out to stop
6720 gpasm complaining and test the linkage with gplink, _linkCmd and
6721 _asmCmd changed to be more gplink and gpasm friendly
6722 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6723 produced an error when parsed, peep rule 12 is added to utilize
6724 movff, but it is commented out since the pCode does not support
6725 yet a command with 2 address arguments
6727 2003-05-18 <johan AT balder>
6729 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
6730 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6756 2003-05-11 Borut Razem <borut.razem AT siol.net>
6758 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6759 the path of bin directory, so that PATH is the only env. variable, which has to be set
6760 in case of standard installation.
6761 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

7845 file with extension .mem. Reports of overlaping stack and small stack
7846 size. If the space for the stack is less than 16 bytes aslink trows a
7849 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7850 the 8051. Option 'y' for memory summary output file.
7852 Changes to sdcc (All the changes are marked with 'JCF'):
7854 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7856 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7857 overlaying area for it (uses RegBankUsed[4]).
7859 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7860 bank zero as used by default. By default aslink locates the stack
7861 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7862 the creation of the .mem file. Delegates the allocation of data area
7863 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7864 the begining of the stack area to aslink.
7866 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7867 glue() in SDCCglue.c creates an area for it.
7869 2002-09-03 Borut Razem <borut.razem AT siol.net>
7870 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7871 sdcc/src/pic/glue.c:
7872 introduced atexit() handler for teporay files removal in case of
7873 errors, assertions, ...
7875 2002-08-29 Borut Razem <borut.razem AT siol.net>
7876 * sdcc/support/cpp2/auto-host_vc_in.h:
7877 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7878 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7879 Maybe there is a similar problem with BORLANDC? It should be checked!
7881 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7882 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7883 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7884 was not executed, and the compiler (cl) launched a warning:
7885 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7887 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7888 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7890 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

7893 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7894 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7895 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7896 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7897 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7898 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7899 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7900 - added Release configuration in VS projects
7901 - review of compiler an linker options
7902 - VC .exe files are generated in bin_vc directory, not to interfere
7903 with binaries generated from other projects (cygwin, mingw, bcc ...)
7905 * sdcc/src/yacc.dsp: added
7907 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7908 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7909 and insert the version number definitions from .version
7911 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7913 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

7922 2002-08-11 Borut Razem <borut.razem AT siol.net>
7923 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7925 2002-08-10 Borut Razem <borut.razem AT siol.net>
7926 * src/SDCCmain.c (main):
7927 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7928 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7929 The consequence was that some temporary files were not removed.
7932 unification of code in functions tempfilename() and tempfile():
7933 function tempnam() is defined in Visual Studio 6.0 and .NET
7935 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7937 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7938 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7939 - removed compiler command line option /WX: Treats all warnings as errors
7940 - update a list of source files, included into the project
7942 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7943 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7944 changed project type to Generic Project so that can be correcly converted to VS.NET project
7946 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7948 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7950 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7952 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7953 added return 0 statements after assert() to make compiler happy
7955 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7956 added newline in the def file to keep MSC compiler satisfied
7958 * sdcc/src/z80/gen.c:
7959 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7960 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7961 - solved MSC error in function aopDump()
7963 * sdcc_vc.h: define PREFIX as "\\sdcc"
7965 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

8014 Added -p option. Allows port dependent processor to be specified.
8017 Initialized the new field char *Processor field to NULL in all ports
8020 Compiler generated registers for interrupt context saving
8021 were not getting allocated.
8023 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8026 Fixed left shift. Will promote the left side of a left shift
8027 if a) left shifting more than size of operand or b) when assigned
8028 to something size > size of left side
8030 2002-03-14 Scott Dattalo <scott AT dattalo.com>

8138 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8140 * sdcc/src/SDCCloop.c:
8141 Previous fix was not good. basic blocks that have "break" or "return" are
8142 not really partof a loop , but live ranges used in these blocks should
8143 be live thru the entire loop, so set partOfLoop but don't add them to
8146 2002-02-21 <johan AT FRIJA>
8148 * src/SDCCcse.c: fixed bug #514308
8150 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

8156 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
8158 2002-02-10 Karl Bongers <karl AT turbobit.com>
