931 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
933 Enabled VPATH feature: changed nearly all Makefiles (149 files).
934 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
936 One basic decision: e.g. src/clean.mk includes further files. In order
937 to make this work there are two solutions:
938 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
939 run configure on them. This way they can use
940 'include $(srcdir)/port-clean.mk'
941 - always include clean.mk by the Makefile at the same level. To avoid
942 that `make clean` tries to include and build Makefile.dep the
943 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
944 implemented, because now even `make uninstall` doesn't create
945 Makefile.in. clean.mk could be eliminated by pasting it in
948 * debugger/mcs51/Makefile.in: build own objects from library sources
949 (SLIB, SDCC) in current directory
951 * configure, configure.in: renamed --disable-device-lib-build in
952 --disable-device-lib; added --enable-doc, the required tools are
953 searched by configure; added result message; the toolchain for the
954 belonging ports are now only built, if the port is enabled.
956 * support/regression/*: all output is written in directory gen, because
957 the fwk and ports directories don't livet in the build tree using vpath
959 * doc/sdccman.lyx: renamed --disable-device-lib-build to
960 --disable-device-lib, added --enable-doc, added section VPATH
962 * sim/ucsim/configure.in,
963 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
964 z80 are enabled by default
966 2006-04-24 Raphael Neider <rneider AT web.de>
968 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
969 to config word, "pic14_"-prefixed some extern functions
970 (pic14_emitConfigWord): emit __config directive(s) if assignment to
971 config word has been found
972 * src/pic/device.h: added prototypes

1282 call to allocReg, not by manually allocating a new one,
1283 (pic16_assignRegisters): now before going through the register
1284 allocating functions mark all registers as free. This eliminates some
1285 side effects resulting from peephole parser done earlier in the backbone

1349 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1350 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1351 port->fun_prefix anymore (may change later),
1352 (genFunction, genEndFunction): do not store/restore local registers for
1353 _main (this should take care the --main-return command line option in
1355 (genOr): removed some legacy pic-port instructions,
1356 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1357 performing operations with SFR's causes data to be written more than
1358 once to each SFR. Perhaps SFRs should be handled in special cases...
1359 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1361 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1362 into account for stack starting position,
1363 (struct OPTIONS pic16_optionsTable): added command line argument
1364 --extended or -y for Extended Instruction Support,
1365 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1366 (deassignLRs): *** perhaps the most important change, old 'for' code
1367 (commented out for reference), didn't account for some registers which
1368 were left marked 'not free' after a pointer operation. The change
1369 reduces register usage a lot in some cases

3644 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3645 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3646 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3647 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3648 always available in leading double underscore form. The C99 support is
3649 mostly missing, but it's a start.

3729 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3731 * device/lib/printf_large.c: removed inline assembly for portability and
3732 readability. Use printf_fast if speed or size are more important.
3733 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3734 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3736 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3738 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3739 prevent compiler warning
3741 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3743 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3744 moved to level 0 and declared as static. Also they are explicit
3745 placed in access bank. This was necessery because some times they
3746 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3747 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3748 optimizations. Currently only compare to unsigned char is implemented,
3749 * src/pic16/gen.c: added fReturnIdx array,
3750 * (struct resolvedIfx) is moved to gen.h and made public,
3751 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3752 * (aopForSym): added an optimization to directly store in stack of
3753 the operand of a SEND iCode,
3754 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3755 but as registers instead (AOP_REG) using the fReturnIdx array,
3756 * (pic16_freeAsmop): remove the freed register from the
3757 _G.sregsAlloc field,
3758 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3759 a compare of 'WREG',
3760 * (pic16_popGetTempRegCond): changed function prototype, now
3761 function takes also a bitVector argument v which holds the current
3762 set of registers that are allocated for stack access by aopForSym,
3763 registers allocated in aopForSym for accessing stack symbols are not
3764 any more part of the functions usedRegs field,
3765 * (genCall): some times aopOp is called for a stack variable to be
3766 send, aopForSym might perform the push, if this is true make sure
3767 that genCall doesn't push the variable twice by testing _G.resDirect,
3768 * (genFunction): changed testing for unspecified interrupt number
3769 from 256 to INTNO_UNSPEC,
3770 * modified selection scheme of frame pointer generation. Previously
3771 if function did use local registers a frame pointer was generated,
3772 now a frame pointer is generated only if function has arguments
3773 (that need PLUSW2 register access), or has stack arguments, or the
3774 compiler is not instructed to omit the frame pointer,
3775 * (genEndFunction): before restoring local registers that were saved
3776 in the function preamble, also restore the registers that *might*
3777 have been allocated for stack access,
3778 * (genRet): removed some old comments,
3779 * (genCmp, the active (RN's) version): added a call to the
3780 pic16_genCmp_special function to perform the compare with a more
3781 robust and optimized way,
3782 * (genInline): a feature has been added in inline code generation,
3783 which allows a wildcard variable substitution when writing inline
3784 assembly. Code is incomplete and experimental therefore undocumented,
3785 * (genCast): changed order of aopOp for result and right to allow
3786 aopForSym to directly load the result if possible,
3787 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3788 perform an optimized compare on some selected special occasions,
3789 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3790 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3791 generate an IVT any more,
3792 * src/pic16/main.c (pic16_optionsTable): added command line option
3794 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3795 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3797 * src/pic16/NOTES: Raphael Neider added in list of active developers
3798 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3799 jumptable_end to prevent bug #,
3800 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3801 inCond and outCond fields,
3802 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3803 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3804 turn off register spilling,
3805 * (packRegsForOneUse): synced with other ports' versions although it
3806 is not used currently,
3807 * (pic16_packRegisters): added an optimization while reading
3808 structure bitfields, some registers may be saved (malloc code is
3809 decreased by 80 bytes)
3811 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3813 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3814 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3815 this can be optimized more?
3817 2005-03-10 Raphael Neider <rneider AT web.de>
3819 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3820 genNearPointerGet): (hopefully) fixed access to bitfields via
3821 pointers (p->bitN = x; and x = p->bitN; failed)

3866 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
3867 to keep the correct label reference count when adding/removing references
3868 to labels. A peephole file using this is appended to patch #1144962.
3870 2005-02-14 Raphael Neider <rneider AT web.de>

4455 Adding support for replacing ljmps with sjmps in jumptables
4456 generated for switch statements. For now you need to set the
4457 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4458 Now 4 algorithms for mcs51 jumptable generation are used:
4459 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4460 addresses loaded pc-relative for up to 112 cases and stack-pushing
4461 target addresses loaded with offset from dptr for up to 256 cases.

4491 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4493 * added libc directory. The current version of LibC contains string
4494 functions, ctype functions and macros and some functions of the
4495 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4496 be extensively tested in the future. Standard disclaimer here.
4497 Library is not automatically build yet. But one can build it by
4498 invoking 'make' inside the libc directory.
4499 * added ADC library under libio. Preliminary version yet.

4509 * (pic16_storeForReturn): optimized return of 0,
4510 * (genCmp): experimental code for new genCmp which uses PIC18's
4511 special compare&skip instructions. Initial tests fail some times
4512 with variables grater than 1 byte in size, so new code is disabled,
4513 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4515 * (genCast): began a fix to optimize the casting of a bit to another
4516 bit, now assigning a bitfield to another bitfield will fail, sorry,

4525 and 1 for banking instruction,
4526 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4527 caused stop processing pCodes after a inline assembly block,
4528 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

4530 registers when it shouldn't,
4531 * src/pic16/ralloc.c (allocReg): add preliminary support for
4532 supporting a limited set of temporary registers,
4534 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4536 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

4540 (genFunction): optimize RECEIVE iCodes in reentrant functions
4542 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7425 virus/worm forged address usage.
7427 2004-01-27 Bernhard Held <bernhard AT bernhardheld.de>
7429 Fixed promotion, it should be done on AST level:

7453 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
7455 * src/SDCCast.c: added an additional type flow in decorateType() of
7456 opposite direction, see feature request #860006; it's enabled at runtime
7457 by setting the environment variable SDCC_NEWTYPEFLOW
7458 * src/SDCCast.h: changed prototype of decorateType()
7459 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
7460 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
7461 'char' to 'int' can be omitted, if both operands are 'unsigned char';

7492 added support for multiple code pages and multiple RAM banks on the
7493 PIC 14 port. The ASM files now no longer simply assume all the
7494 code / RAM are in the same page / bank. This means the linker can
7495 safely allocate code/RAM of separate ASM files to different pages/banks.
7496 * doc/sdccman.lyx: added Slade's tips
7497 * src/mcs51/peeph.def: fixed bug #880768

7539 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7541 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7542 loaded with the linker search paths (-L arguments) and the libraries
7543 to be linked with the current source (-l arguments). Changes
7544 currently will affect only the pic16 port.
7545 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7546 include path the port specific paths and port specific libraries,
7547 * gplink command now contains the $3 argument,
7548 * src/pic16/device.h,
7549 * src/pic16/device.c,: structure PIC_device is made public and
7550 renamed to PIC16_device, the same for variable Pics which is renamed

7565 Documenting changes from previous commits.
7566 * configure.in (version 1.56),
7567 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7568 when generating output files to configure the pic16 library,
7569 but now I've commented it out, since gputils aren't installed in the
7570 SF compile farm, so library won't compile
7572 * device/lib/Makefile.in (version 1.56): initially I've added in
7573 target 'all' the prerequestive 'model-pic16' so it compiled the
7574 pic16 library, but now I've commented it out for the same reasons
7576 * added targets 'model-pic16' and 'objects-pic16' to compile the
7578 * added target 'port-specific-objects-pic16' to handle the
7579 generated libraries and copy them into the build/ directory
7580 * added target 'clean-intermediate-pic16' to clean intermediate
7581 files into pic16 directory
7582 * in target 'installdirs' added line to create directory pic16 in
7583 the installation path
7585 * device/include/Makefile.in (version 1.11): in target 'install'
7586 added lines to copy all header files to installation path,
7587 * in target 'installdirs' added line create directory for pic16
7588 headers in the installation path

7603 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7604 option so that it actually works. Made it specific to the z80, since
7605 the gbz80 doesn't have these kinds of I/O ports.
7607 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7609 * device/include/z180.h,

7633 via literal number. The symbol is placed in the corresponding
7634 position of the data ram
7635 * (pic16_dump_section): relocatable and absolute uninitialized
7636 data are now emitted in sorted order to reduce section naming,
7637 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7638 weren't marked as being in the access bank,
7640 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7642 Added portion of GNU PIC Library under the directory
7643 device/include/pic16 and device/lib/pic16. These files
7644 contain the declarations of SFRs for the PIC18Fxx2 devices.
7645 The directory is initialized via configure from toplevel.

7675 all over. Telling LaTeX to be less strict with word spacing
7676 to better keep the right margin. Changed some notes about
7677 maintainance of the ports in section 3.2.1 - is it OK like this?

7873 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7875 PIC16 port related changes:
7876 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7877 added variable stackPos,
7879 * gen.c: genCall, assignResultValue: added support for
7880 pushing/retrieving function parameters to/from stack,
7881 genFunction,genEndFunction: setup stack frame for the
7883 genAddrOf: will be changed according to bug 863624
7885 * added files genutils.c and genutils.h which contain gen*
7886 debugged and optimised functions extracted from gen.c
7888 * glue.c: added variable 'externs' which holds extern symbols,
7889 pic16emitRegularMap: is modified to properly handle relocatable
7890 symbols under the new scheme,
7891 pic16createInterruptVect: is modified
7892 pic16printPublics: is modified to emit 'global' assembler directives,
7893 added pic16_printExterns to print extern symbols,
7894 pic16glue: initializes stack/frame pointer in the beginning of
7895 the assembly output. Temporary hack, will be corrected later,
7896 because gplink yet does not support stack and SDCC does not
7897 yet support a type of crt0.o object to create the final binary.
7899 * Removed many lines that contain 8051 legacy code.
7900 * The code is finally placed under a 'code' directive.
7901 * Added port specific options.
7903 * _process_pragma: simplified since now we do not need *special*
7904 include file to define SFR registers. But a separate header
7905 will be needed. This will be developed later.
7906 * _pic16_parseOptions: added, parses port specific options:
7907 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7908 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7909 --preplace-udata-with=
7911 * _pic16_setDefaultOptions: modified to initialize section names,
7912 but hack is temporarly out of order since it needs improvement.
7913 * _pic16_genAssemblerPreamble: configuration words are emitted by
7914 their address instead of their name. This part is incomplete and
7915 supports only the 18Fxx2 devices. Other devices will emit an error
7916 during assembly since they do not contain the same set of config
7918 * _pic16_genIVT: is modified,
7920 * pcode.c: added definitions for some hardware registers that are needed
7922 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7923 All PCI entries are updated. Now LFSR is supported.
7924 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7925 * added pic16_newpCodeOpLit2 to support instructions with
7926 two literal arguments
7927 * pic16_pCode2str: corrected code that emits assembler instructions
7928 with two literal operands and those that have an access bit modifier
7929 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7930 this fixes a bug which caused some labels to be lost, when an
7931 assembler directive was added, i.e. banksel,
7932 * pic16_FixRegisterBanking: improved logic that causes the insertion
7934 * InlineFunction: functions that are called once, are not any more
7935 inlined. This can be a port option in the future,
7937 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7939 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7940 hold the corresponding uninitialized symbols,
7941 * pic16_allocProcessorRegister: registers have explicit marked the
7943 * pic16_allocInternalRegister: registers are explicit marked as
7945 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7946 processing list, so bit registers were lost,
7949 * ralloc.h: added field 'accessBank' and original symbol operand
7950 in register definition,
7951 * removed the field isMapped from register definition,
7953 ** Several functions have been removed from various sources:
7954 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7955 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7956 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7957 pic16_assignRelocatableRegisters
7959 ** others have been introduced:
7960 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7961 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7963 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7965 * support/scripts/inc2h.pl: changed definition of BIT_AT
7966 to emit 'sbit at' instead of 'bit at'. This was a request.
7968 PIC16 port related preliminary changes:
7969 * gen.c: prefixed function popRegFromString with
7970 pic16_ and all references to it corrected
7971 * pcode.c: all pic16_pc_* hardware registers prefixed
7972 with underscore (_),
7973 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7974 * ralloc.c: newReg(): when register is REG_SFR then
7975 set address to rIdx,
7976 pic16_allocProcessorRegister(): marks register wasUsed=0
7977 pic16_writeUsedRegs(): added a call to assign processor
7978 registers via pic16_assignFixedRegisters
7980 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7982 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7983 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7984 variables in unused register banks. Also the SSEG is placed
7985 wherever there is enough space for it, and IDATA can be anywhere
7986 in internal RAM. For now compile using -Wl-Y[stack_size].
7987 The mem file is different for this option as well, since it
7988 makes no sense of talking about DSEG lenght.
7990 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7992 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7993 in certain cases, e.g. when ROM assignment, patch provided
7994 from Albert den Haan.

8235 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8237 * src/SDCCast.c (decorateType): disabled a transformation I added in
8238 revision 1.188 (access to fields of a structure at an absolute address);
8239 it breaks with bitfields, extern declarations, and gcse analysis.
8240 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8241 could be assigned through a pointer, so don't complain.
8242 * src/SDCCast.c (astErrors),
8244 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8346 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
8347 uninitialized variables) for the mcs51. Set environment variable
8348 SDCC_GENRAMCLEAR to test.
8349 xdata initialization slightly shorter
8351 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9001 copied from genNearPointerSet()
9002 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9003 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

9019 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9020 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9021 type for bits was changed. It resulted in bit variables becoming
9022 global, which is not permitted in PIC 14 assembly output.
9024 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

9039 A few small changes that speed up the peephole optimizer.
9043 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9045 Try to make the peephole optimizer smarter by maintaining
9046 an association between the assembly source code and the
9047 iCodes that originated them. Put this information to use
9048 with a new peephole rule condition "notVolatile" so that
9049 the rules can be aggressive yet still safe.
9054 * src/mcs51/peeph.def
9056 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9060 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9061 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9062 if the left or right operand symbols have the accuse flag set.
9064 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9066 Changed the type of the result of the ! (NOT) operator to char;
9067 previously it returned the same type as the source. This allows
9068 us to eliminate all the genFloatNot functions (all of its target
9069 implementations were very buggy) since !float can use the same

9081 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9082 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9083 during interrupts. Ensure WSAVE is located at a shared bank address.
9084 2. Fixed page selection in some places
9085 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9086 the registers name strings.
9087 4. Fixed "signed / unsigned compare" compiler warnings.
9088 5. The PIC port manages its own allocation of the general purpose
9089 registers, but makes no attempt to reuse them. As a result when
9090 compiling it soon runs out of general purpose registers. Some
9091 additional code was added to the files pcode.c and device.c to walk
9092 through the function call tree and rename the registers so that they
9102 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

9109 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9111 Made bitfield a distinct type from bit so that bitfields
9112 convert as per ANSI C and bits retain their traditional
9113 boolean style behaviour. Implemented bitfield support in
9121 * src/ds390/gen.c: bit v bitfield split
9122 * src/z80/gen.c: New support for bitfields
9123 * support/regression/tests/bitfields.c: reenabled z80,
9126 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9128 Rules 246.x, 247.x relate to bitfields, the others speed up
9129 access to xdata mapped I/O devices.
9131 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9133 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9135 Cleaned up genPackBits and genUnpackBits and added two helper
9136 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9137 for literal assignments in genPackBits (thanks to Frieder for
9143 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9145 Fixed bug #748310 (pointer to function type mishandled when the
9146 function name is omitted). Also fixed a SIGSEGV when a function
9147 attribute (reentrant, etc) is used on a non-function or on a
9148 function but misplaced before the parameter list.
9150 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9152 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

9175 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9177 Made the constant following the "interrupt" keyword optional. If
9178 omitted, the function will not automatically be given an entry
9179 in the interrupt vector table (similar to #pragma NOIV, but
9180 less syntacticly kludgy). The interrupt number is also now
9181 range checked. Also fixed a bug in the high order bit example

9195 * src/SDCCicode.c (operandOperation): rewritten some ops
9196 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9197 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9199 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9200 be re-activated by defining REDUCE_LITERALS)
9201 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9202 unsigned, but are signed by default
9203 * src/SDCCval.c (constVal): rearranged
9204 * src/SDCCval.c (valMod): preliminary fix
9205 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9710 * src/SDCCmain.c: linkOptions is changed to set *,
9711 added if/endif conditional macros to remove options help
9712 messages from optionsTable when a port is not configured, added
9713 support for the PIc16 port in the ports table, when executing
9714 the compiler with no port specified on command line, a default
9715 port is selected with the new macro DEFAULT_PORT which is
9716 defined in port.h, in setDefaultOptions() linkOptions is removed
9717 from initialization assignment, since now it is a set,
9718 parseCmdLine uses setParseWithComma for linkOptions, in
9719 linkEdit() linkOptions are accessed with new function indexSet()
9720 which returns the i'th item of a set variable. See SDCCset.c, in
9721 linkEdit() when calling buildCmdLine(), added linkOptions as
9722 last argument. Now users can pass arguments to gplink via the
9723 -Wl option, main() uses pic16glue() to glue up pic16 programs

9736 * src/pic16/main.c: __config directives are commented out to stop
9737 gpasm complaining and test the linkage with gplink, _linkCmd and
9738 _asmCmd changed to be more gplink and gpasm friendly
9739 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9740 produced an error when parsed, peep rule 12 is added to utilize
9741 movff, but it is commented out since the pCode does not support
9742 yet a command with 2 address arguments
9744 2003-05-18 <johan AT balder>
9746 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9773 2003-05-11 Borut Razem <borut.razem AT siol.net>
9775 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9776 the path of bin directory, so that PATH is the only env. variable, which has to be set
9777 in case of standard installation.

10792 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
10794 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10795 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
10796 * support/regression/tests/bug-524697.c: fit mem usage into 8032
10798 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10799 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
10801 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10802 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10804 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10805 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10807 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10809 * in /sdcc/as/mcs51/ changed these files in order to create an
10810 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10811 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10812 following files to include the previous two files: aslink.dsp,
10813 Makefile.aslink, Makefile.bcc, and Makefile.in.
10815 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
10816 .adb instead of .cdb
10818 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10820 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
10821 value from option --iram-size.
10823 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10825 * /sdcc/as/mcs51/lklist.c: added boundary check before using
10828 2002-09-18 <wiml AT hhhh.org>
10830 * SDCClrange.h: exposed setFromRange() and setToRange()
10831 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10832 packRegsForAccUse() (bug 542397)
10833 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10834 multiple times and emitting the fetch operations more than once
10835 added aopGetUsesAcc() function to allow binary operators to
10836 fetch their operands in the correct order; made genMinus() emit
10837 compact code for X = LITERAL - Y
10839 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10840 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
10841 sprintf() in line 1267.
10843 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10844 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10847 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10848 Changes to aslink (All the changes are marked with 'JCF'):
10850 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
10853 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
10854 area BSEG. Also moves, if possible, the DATA area down into the internal
10855 ram so more space is available.
10857 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
10860 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
10861 not bytes. Function summary() which creates a memory usage summary
10862 file with extension .mem. Reports of overlaping stack and small stack
10863 size. If the space for the stack is less than 16 bytes aslink trows a
10866 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
10867 the 8051. Option 'y' for memory summary output file.
10869 Changes to sdcc (All the changes are marked with 'JCF'):
10871 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
10873 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
10874 overlaying area for it (uses RegBankUsed[4]).
10876 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
10877 bank zero as used by default. By default aslink locates the stack
10878 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10879 the creation of the .mem file. Delegates the allocation of data area
10880 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10881 the begining of the stack area to aslink.
10883 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
10884 glue() in SDCCglue.c creates an area for it.
10886 2002-09-03 Borut Razem <borut.razem AT siol.net>
10887 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10888 sdcc/src/pic/glue.c:
10889 introduced atexit() handler for teporay files removal in case of
10890 errors, assertions, ...
10892 2002-08-29 Borut Razem <borut.razem AT siol.net>
10893 * sdcc/support/cpp2/auto-host_vc_in.h:
10894 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10895 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10896 Maybe there is a similar problem with BORLANDC? It should be checked!
10898 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10899 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10900 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10901 was not executed, and the compiler (cl) launched a warning:
10902 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10904 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10905 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10907 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10908 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10910 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10911 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10912 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10913 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10914 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10915 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10916 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10917 - added Release configuration in VS projects
10918 - review of compiler an linker options
10919 - VC .exe files are generated in bin_vc directory, not to interfere
10920 with binaries generated from other projects (cygwin, mingw, bcc ...)
10922 * sdcc/src/yacc.dsp: added
10924 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10925 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10926 and insert the version number definitions from .version
10928 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10930 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10931 added - genarate auto-host.h using auto-host_vc_in.h as template
10934 removed from CVS, generated automatically
10936 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10937 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10939 2002-08-11 Borut Razem <borut.razem AT siol.net>
10940 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10942 2002-08-10 Borut Razem <borut.razem AT siol.net>
10943 * src/SDCCmain.c (main):
10944 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10945 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10946 The consequence was that some temporary files were not removed.
10949 unification of code in functions tempfilename() and tempfile():
10950 function tempnam() is defined in Visual Studio 6.0 and .NET
10952 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10954 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10955 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10956 - removed compiler command line option /WX: Treats all warnings as errors
10957 - update a list of source files, included into the project
10959 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10960 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10961 changed project type to Generic Project so that can be correcly converted to VS.NET project
10963 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10965 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10967 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10969 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10970 added return 0 statements after assert() to make compiler happy
10972 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10973 added newline in the def file to keep MSC compiler satisfied
10975 * sdcc/src/z80/gen.c:
10976 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10977 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10978 - solved MSC error in function aopDump()
10980 * sdcc_vc.h: define PREFIX as "\\sdcc"
10982 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10983 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10986 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10987 - Rewrote the register banking algorithm.
10988 - Added pCode live-range analysis to registers (for now, only non-used and
10989 singly-used registers optimized away)
10991 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10993 * 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.

11020 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11022 2002-03-28 Johan Knol <johan AT balder>
11024 * src/SDCCval.c: fixed bug #532436
11026 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11028 Added "char *Processor" field to the port structure.
11031 Added -p option. Allows port dependent processor to be specified.
11034 Initialized the new field char *Processor field to NULL in all ports
11037 Compiler generated registers for interrupt context saving
11038 were not getting allocated.
11040 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11043 Fixed left shift. Will promote the left side of a left shift
11044 if a) left shifting more than size of operand or b) when assigned
11045 to something size > size of left side
11047 2002-03-14 Scott Dattalo <scott AT dattalo.com>

11155 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11157 * sdcc/src/SDCCloop.c:
11158 Previous fix was not good. basic blocks that have "break" or "return" are
11159 not really partof a loop , but live ranges used in these blocks should
11160 be live thru the entire loop, so set partOfLoop but don't add them to
11163 2002-02-21 <johan AT FRIJA>
11165 * src/SDCCcse.c: fixed bug #514308
11167 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
11170 Fixed BUG #519583. If a conditional block ended in a return/break
