914 Enabled VPATH feature: changed nearly all Makefiles (149 files).
915 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
917 One basic decision: e.g. src/clean.mk includes further files. In order
918 to make this work there are two solutions:
919 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
920 run configure on them. This way they can use
921 'include $(srcdir)/port-clean.mk'
922 - always include clean.mk by the Makefile at the same level. To avoid
923 that `make clean` tries to include and build Makefile.dep the
924 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
925 implemented, because now even `make uninstall` doesn't create
926 Makefile.in. clean.mk could be eliminated by pasting it in
929 * debugger/mcs51/Makefile.in: build own objects from library sources
930 (SLIB, SDCC) in current directory
932 * configure, configure.in: renamed --disable-device-lib-build in

1195 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
1197 * src/mcs51/gen.c (genCall): fixed bug 1457608
1199 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

1218 implemented patch 1120823 Thanks to Willy De la Court (normal
1219 interrupts need an interrupt number now if they are made critical),
1220 and enabled nesting of critical functions though not for gbz80
1221 (genCritical, genEndCritical): added functions
1222 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1223 * src/z80/mappings.i: added "ei" to all mappings

1232 2006-03-16 Raphael Neider <rneider AT web.de>
1234 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1235 the left operand is shorter than the result (c* = lit-c* + int),
1237 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1240 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1242 * src/.version: increased version number to 2.5.5
1243 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1244 linking is done manually in pic16 port's _linkEdit,
1245 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1246 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1247 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1248 allocate asmop as AOP_ACC,
1249 (aopForRemat): added parameter 'bool result' in function declaration,
1250 (pic16_aopGet): return AOP_ACC when accessing WREG,
1251 (pic16_popGetTempReg): minor modification,

1262 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1263 call to allocReg, not by manually allocating a new one,
1264 (pic16_assignRegisters): now before going through the register
1265 allocating functions mark all registers as free. This eliminates some
1266 side effects resulting from peephole parser done earlier in the backbone
1268 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1270 * src/SDCCicode.c (geniCodeLogic),

1316 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
1318 2006-03-06 Borut Razem <borut.razem AT siol.net>
1320 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1321 made the linker quiet
1323 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1325 * src/pic16/gen.c (genPcall): fixed bug #1443644
1326 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1327 which dumps before the function entry point a data byte which represents
1328 the number of the local variables used by the specified function, added
1329 'xinst' for initial support for Extended Instruction Support,
1330 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1331 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1332 port->fun_prefix anymore (may change later),
1333 (genFunction, genEndFunction): do not store/restore local registers for
1334 _main (this should take care the --main-return command line option in
1336 (genOr): removed some legacy pic-port instructions,
1337 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1338 performing operations with SFR's causes data to be written more than
1339 once to each SFR. Perhaps SFRs should be handled in special cases...
1340 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1342 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1343 into account for stack starting position,
1344 (struct OPTIONS pic16_optionsTable): added command line argument
1345 --extended or -y for Extended Instruction Support,
1346 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1347 (deassignLRs): *** perhaps the most important change, old 'for' code
1348 (commented out for reference), didn't account for some registers which
1349 were left marked 'not free' after a pointer operation. The change
1350 reduces register usage a lot in some cases
1352 2006-03-04 Borut Razem <borut.razem AT siol.net>
1354 * support/regression/ports/hc08/spec.mk: remove *.asm in traget
1356 * support/regression/tests/bug-524697.c: decreased array size for

3625 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3626 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3627 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3628 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3629 always available in leading double underscore form. The C99 support is
3630 mostly missing, but it's a start.
3631 * support/regression/tests/bug-227710.c: fixed nonconforming use of

3710 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3712 * device/lib/printf_large.c: removed inline assembly for portability and
3713 readability. Use printf_fast if speed or size are more important.
3714 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3715 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3717 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3719 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3720 prevent compiler warning
3722 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3724 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3725 moved to level 0 and declared as static. Also they are explicit
3726 placed in access bank. This was necessery because some times they
3727 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3728 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3729 optimizations. Currently only compare to unsigned char is implemented,
3730 * src/pic16/gen.c: added fReturnIdx array,
3731 * (struct resolvedIfx) is moved to gen.h and made public,
3732 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3733 * (aopForSym): added an optimization to directly store in stack of
3734 the operand of a SEND iCode,
3735 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3736 but as registers instead (AOP_REG) using the fReturnIdx array,
3737 * (pic16_freeAsmop): remove the freed register from the
3738 _G.sregsAlloc field,
3739 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3740 a compare of 'WREG',
3741 * (pic16_popGetTempRegCond): changed function prototype, now
3742 function takes also a bitVector argument v which holds the current
3743 set of registers that are allocated for stack access by aopForSym,
3744 registers allocated in aopForSym for accessing stack symbols are not
3745 any more part of the functions usedRegs field,
3746 * (genCall): some times aopOp is called for a stack variable to be
3747 send, aopForSym might perform the push, if this is true make sure
3748 that genCall doesn't push the variable twice by testing _G.resDirect,
3749 * (genFunction): changed testing for unspecified interrupt number
3750 from 256 to INTNO_UNSPEC,
3751 * modified selection scheme of frame pointer generation. Previously
3752 if function did use local registers a frame pointer was generated,
3753 now a frame pointer is generated only if function has arguments
3754 (that need PLUSW2 register access), or has stack arguments, or the
3755 compiler is not instructed to omit the frame pointer,
3756 * (genEndFunction): before restoring local registers that were saved
3757 in the function preamble, also restore the registers that *might*
3758 have been allocated for stack access,
3759 * (genRet): removed some old comments,
3760 * (genCmp, the active (RN's) version): added a call to the
3761 pic16_genCmp_special function to perform the compare with a more
3762 robust and optimized way,
3763 * (genInline): a feature has been added in inline code generation,
3764 which allows a wildcard variable substitution when writing inline
3765 assembly. Code is incomplete and experimental therefore undocumented,
3766 * (genCast): changed order of aopOp for result and right to allow
3767 aopForSym to directly load the result if possible,
3768 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3769 perform an optimized compare on some selected special occasions,
3770 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3771 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3772 generate an IVT any more,
3773 * src/pic16/main.c (pic16_optionsTable): added command line option
3775 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3776 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3778 * src/pic16/NOTES: Raphael Neider added in list of active developers
3779 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3780 jumptable_end to prevent bug #,
3781 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3782 inCond and outCond fields,
3783 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3784 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3785 turn off register spilling,
3786 * (packRegsForOneUse): synced with other ports' versions although it
3787 is not used currently,
3788 * (pic16_packRegisters): added an optimization while reading
3789 structure bitfields, some registers may be saved (malloc code is
3790 decreased by 80 bytes)
3792 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3794 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3795 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3796 this can be optimized more?
3798 2005-03-10 Raphael Neider <rneider AT web.de>
3800 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3801 genNearPointerGet): (hopefully) fixed access to bitfields via
3802 pointers (p->bitN = x; and x = p->bitN; failed)

3848 to keep the correct label reference count when adding/removing references
3849 to labels. A peephole file using this is appended to patch #1144962.

4436 Adding support for replacing ljmps with sjmps in jumptables
4437 generated for switch statements. For now you need to set the
4438 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4439 Now 4 algorithms for mcs51 jumptable generation are used:
4440 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4441 addresses loaded pc-relative for up to 112 cases and stack-pushing
4442 target addresses loaded with offset from dptr for up to 256 cases.

4472 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4474 * added libc directory. The current version of LibC contains string
4475 functions, ctype functions and macros and some functions of the
4476 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4477 be extensively tested in the future. Standard disclaimer here.
4478 Library is not automatically build yet. But one can build it by
4479 invoking 'make' inside the libc directory.
4480 * added ADC library under libio. Preliminary version yet.

4490 * (pic16_storeForReturn): optimized return of 0,
4491 * (genCmp): experimental code for new genCmp which uses PIC18's
4492 special compare&skip instructions. Initial tests fail some times
4493 with variables grater than 1 byte in size, so new code is disabled,
4494 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4496 * (genCast): began a fix to optimize the casting of a bit to another
4497 bit, now assigning a bitfield to another bitfield will fail, sorry,
4498 * src/pic16/main.c: disabled the use of lr-support feature,
4499 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4506 and 1 for banking instruction,
4507 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4508 caused stop processing pCodes after a inline assembly block,
4509 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

4511 registers when it shouldn't,
4512 * src/pic16/ralloc.c (allocReg): add preliminary support for
4513 supporting a limited set of temporary registers,
4515 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4517 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

4521 (genFunction): optimize RECEIVE iCodes in reentrant functions
4523 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7411 * src/SDCCast.c (addCast): added promotion to int
7412 (decorateType): updated call to upCast()
7413 * src/SDCCicode.c (geniCodeLeftShift): removed call to
7414 usualUnaryConversions()
7416 2004-01-26 Michael Hope <michaelh AT juju.net.nz>
7418 * support/regression/tests/literalop.c (mulWrapper): Added a
7419 wrapper to remove integer overflow warnings.
7421 * support/regression/tests/float_trans.c: Made work on host.
7423 * support/regression/ports/ucz80/spec.mk (UCZ80): Made detect the
7426 * support/regression/generate-cases.py (main): Changed from inline
7429 * doc/Makefile (install): Changed to depth first to get rid of
7430 missing directory install warning.
7432 * as/Makefile (install-doc): Made work on Mac.
7434 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
7436 * src/SDCCast.c: added an additional type flow in decorateType() of
7437 opposite direction, see feature request #860006; it's enabled at runtime
7438 by setting the environment variable SDCC_NEWTYPEFLOW
7439 * src/SDCCast.h: changed prototype of decorateType()
7440 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
7441 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
7442 'char' to 'int' can be omitted, if both operands are 'unsigned char';
7443 see feature request #877103
7444 * src/SDCCval.c: updated call of decorateType()
7445 (valBitwise): fixed bug #882876
7446 (valMinus): added promotion
7447 (valLogicAndOr): result is unsigned
7448 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
7449 * src/SDCCsymt.c (computeType),
7450 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
7451 must not cause an unsigned operation
7452 * src/pic/glue (pic14emitRegularMap),

7472 * src/pic/ralloc.h: applied patch from Slade Rich;
7473 added support for multiple code pages and multiple RAM banks on the
7474 PIC 14 port. The ASM files now no longer simply assume all the
7475 code / RAM are in the same page / bank. This means the linker can
7476 safely allocate code/RAM of separate ASM files to different pages/banks.
7477 * doc/sdccman.lyx: added Slade's tips
7478 * src/mcs51/peeph.def: fixed bug #880768

7490 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
7491 strtof is not part of C89 and isn't included with Mac OS X.
7493 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7495 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

7520 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7522 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7523 loaded with the linker search paths (-L arguments) and the libraries
7524 to be linked with the current source (-l arguments). Changes
7525 currently will affect only the pic16 port.
7526 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7527 include path the port specific paths and port specific libraries,
7528 * gplink command now contains the $3 argument,
7529 * src/pic16/device.h,
7530 * src/pic16/device.c,: structure PIC_device is made public and
7531 renamed to PIC16_device, the same for variable Pics which is renamed

7546 Documenting changes from previous commits.
7547 * configure.in (version 1.56),
7548 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7549 when generating output files to configure the pic16 library,
7550 but now I've commented it out, since gputils aren't installed in the
7551 SF compile farm, so library won't compile
7553 * device/lib/Makefile.in (version 1.56): initially I've added in
7554 target 'all' the prerequestive 'model-pic16' so it compiled the
7555 pic16 library, but now I've commented it out for the same reasons
7557 * added targets 'model-pic16' and 'objects-pic16' to compile the
7559 * added target 'port-specific-objects-pic16' to handle the
7560 generated libraries and copy them into the build/ directory
7561 * added target 'clean-intermediate-pic16' to clean intermediate
7562 files into pic16 directory
7563 * in target 'installdirs' added line to create directory pic16 in
7564 the installation path

7567 added lines to copy all header files to installation path,
7568 * in target 'installdirs' added line create directory for pic16
7569 headers in the installation path

7584 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7585 option so that it actually works. Made it specific to the z80, since
7586 the gbz80 doesn't have these kinds of I/O ports.
7588 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7590 * device/include/z180.h,

7612 Mainly changes to support compilation of the device libraries
7613 * src/pic16/device.c: stack is allocated via symbol and not
7614 via literal number. The symbol is placed in the corresponding
7615 position of the data ram
7616 * (pic16_dump_section): relocatable and absolute uninitialized
7617 data are now emitted in sorted order to reduce section naming,
7618 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7619 weren't marked as being in the access bank,
7621 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7623 Added portion of GNU PIC Library under the directory
7624 device/include/pic16 and device/lib/pic16. These files
7625 contain the declarations of SFRs for the PIC18Fxx2 devices.
7626 The directory is initialized via configure from toplevel.

7656 all over. Telling LaTeX to be less strict with word spacing
7657 to better keep the right margin. Changed some notes about
7658 maintainance of the ports in section 3.2.1 - is it OK like this?
7660 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7700 * src/pic16/peeph.def: all peepholes with movff are commented out,
7701 because there is a problem in the pcode peep optimizer,
7702 * src/pic16/ralloc.c: the register allocator can now reuse local

7841 Bug reported from Jesus Calvino-Fraga
7843 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7845 * sdcc.spec: updated
7846 * device/include/Makefile.in: don't install CVS directories

7854 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7856 PIC16 port related changes:
7857 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7858 added variable stackPos,
7860 * gen.c: genCall, assignResultValue: added support for
7861 pushing/retrieving function parameters to/from stack,
7862 genFunction,genEndFunction: setup stack frame for the
7864 genAddrOf: will be changed according to bug 863624
7866 * added files genutils.c and genutils.h which contain gen*
7867 debugged and optimised functions extracted from gen.c
7869 * glue.c: added variable 'externs' which holds extern symbols,
7870 pic16emitRegularMap: is modified to properly handle relocatable
7871 symbols under the new scheme,
7872 pic16createInterruptVect: is modified
7873 pic16printPublics: is modified to emit 'global' assembler directives,
7874 added pic16_printExterns to print extern symbols,
7875 pic16glue: initializes stack/frame pointer in the beginning of
7876 the assembly output. Temporary hack, will be corrected later,
7877 because gplink yet does not support stack and SDCC does not
7878 yet support a type of crt0.o object to create the final binary.
7880 * Removed many lines that contain 8051 legacy code.
7881 * The code is finally placed under a 'code' directive.
7882 * Added port specific options.
7884 * _process_pragma: simplified since now we do not need *special*
7885 include file to define SFR registers. But a separate header
7886 will be needed. This will be developed later.
7887 * _pic16_parseOptions: added, parses port specific options:
7888 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7889 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7890 --preplace-udata-with=
7892 * _pic16_setDefaultOptions: modified to initialize section names,
7893 but hack is temporarly out of order since it needs improvement.
7894 * _pic16_genAssemblerPreamble: configuration words are emitted by
7895 their address instead of their name. This part is incomplete and
7896 supports only the 18Fxx2 devices. Other devices will emit an error
7897 during assembly since they do not contain the same set of config
7899 * _pic16_genIVT: is modified,
7901 * pcode.c: added definitions for some hardware registers that are needed
7903 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7904 All PCI entries are updated. Now LFSR is supported.
7905 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7906 * added pic16_newpCodeOpLit2 to support instructions with
7907 two literal arguments
7908 * pic16_pCode2str: corrected code that emits assembler instructions
7909 with two literal operands and those that have an access bit modifier
7910 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7911 this fixes a bug which caused some labels to be lost, when an
7912 assembler directive was added, i.e. banksel,
7913 * pic16_FixRegisterBanking: improved logic that causes the insertion
7915 * InlineFunction: functions that are called once, are not any more
7916 inlined. This can be a port option in the future,
7918 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7920 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7921 hold the corresponding uninitialized symbols,
7922 * pic16_allocProcessorRegister: registers have explicit marked the
7924 * pic16_allocInternalRegister: registers are explicit marked as
7926 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7927 processing list, so bit registers were lost,
7930 * ralloc.h: added field 'accessBank' and original symbol operand
7931 in register definition,
7932 * removed the field isMapped from register definition,
7934 ** Several functions have been removed from various sources:
7935 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7936 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7937 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7938 pic16_assignRelocatableRegisters
7940 ** others have been introduced:
7941 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7942 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7944 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7946 * support/scripts/inc2h.pl: changed definition of BIT_AT
7947 to emit 'sbit at' instead of 'bit at'. This was a request.
7949 PIC16 port related preliminary changes:
7950 * gen.c: prefixed function popRegFromString with
7951 pic16_ and all references to it corrected
7952 * pcode.c: all pic16_pc_* hardware registers prefixed
7953 with underscore (_),
7954 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7955 * ralloc.c: newReg(): when register is REG_SFR then
7956 set address to rIdx,
7957 pic16_allocProcessorRegister(): marks register wasUsed=0
7958 pic16_writeUsedRegs(): added a call to assign processor
7959 registers via pic16_assignFixedRegisters
7961 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7963 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7964 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7965 variables in unused register banks. Also the SSEG is placed
7966 wherever there is enough space for it, and IDATA can be anywhere
7967 in internal RAM. For now compile using -Wl-Y[stack_size].
7968 The mem file is different for this option as well, since it
7969 makes no sense of talking about DSEG lenght.
7971 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7973 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7974 in certain cases, e.g. when ROM assignment, patch provided
7975 from Albert den Haan.

8218 * src/SDCCast.c (decorateType): disabled a transformation I added in
8219 revision 1.188 (access to fields of a structure at an absolute address);
8220 it breaks with bitfields, extern declarations, and gcse analysis.
8221 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8222 could be assigned through a pointer, so don't complain.

8330 xdata initialization slightly shorter
8332 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8982 copied from genNearPointerSet()
8983 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8984 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

9000 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9001 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9002 type for bits was changed. It resulted in bit variables becoming
9003 global, which is not permitted in PIC 14 assembly output.
9005 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9007 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9018 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9020 A few small changes that speed up the peephole optimizer.
9024 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9026 Try to make the peephole optimizer smarter by maintaining
9027 an association between the assembly source code and the
9028 iCodes that originated them. Put this information to use
9029 with a new peephole rule condition "notVolatile" so that
9030 the rules can be aggressive yet still safe.
9035 * src/mcs51/peeph.def
9037 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9041 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9042 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9043 if the left or right operand symbols have the accuse flag set.
9045 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9047 Changed the type of the result of the ! (NOT) operator to char;
9048 previously it returned the same type as the source. This allows
9049 us to eliminate all the genFloatNot functions (all of its target
9050 implementations were very buggy) since !float can use the same
9053 * src/SDCCicode.c (ast2iCode): ! returns char
9054 * src/mcs51/gen.c (genNot, genNotFloat),
9055 * src/ds390/gen.c (genNot, genNotFloat),
9056 * src/z80/gen.c (genNot, genNotFloat),
9057 * src/pic/gen.c (genNot, genNotFloat),
9058 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
9060 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
9062 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9063 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9064 during interrupts. Ensure WSAVE is located at a shared bank address.
9065 2. Fixed page selection in some places
9066 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9067 the registers name strings.
9068 4. Fixed "signed / unsigned compare" compiler warnings.
9069 5. The PIC port manages its own allocation of the general purpose
9070 registers, but makes no attempt to reuse them. As a result when
9071 compiling it soon runs out of general purpose registers. Some
9072 additional code was added to the files pcode.c and device.c to walk
9073 through the function call tree and rename the registers so that they
9083 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9084 genPlus() & genMinus() when the result is the same as left or right

9090 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9092 Made bitfield a distinct type from bit so that bitfields
9093 convert as per ANSI C and bits retain their traditional
9094 boolean style behaviour. Implemented bitfield support in
9102 * src/ds390/gen.c: bit v bitfield split
9103 * src/z80/gen.c: New support for bitfields
9104 * support/regression/tests/bitfields.c: reenabled z80,
9107 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9109 Rules 246.x, 247.x relate to bitfields, the others speed up
9110 access to xdata mapped I/O devices.
9112 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9114 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9116 Cleaned up genPackBits and genUnpackBits and added two helper
9117 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9118 for literal assignments in genPackBits (thanks to Frieder for
9124 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9126 Fixed bug #748310 (pointer to function type mishandled when the
9127 function name is omitted). Also fixed a SIGSEGV when a function
9128 attribute (reentrant, etc) is used on a non-function or on a
9129 function but misplaced before the parameter list.
9131 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9133 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9134 * support/Util/SDCCerr.h,

9156 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9158 Made the constant following the "interrupt" keyword optional. If
9159 omitted, the function will not automatically be given an entry
9160 in the interrupt vector table (similar to #pragma NOIV, but
9161 less syntacticly kludgy). The interrupt number is also now
9162 range checked. Also fixed a bug in the high order bit example
9169 * support/Util/SDCCerr.c
9170 * support/Util/SDCCerr.h
9173 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

9176 * src/SDCCicode.c (operandOperation): rewritten some ops
9177 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9178 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9180 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9181 be re-activated by defining REDUCE_LITERALS)
9182 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9183 unsigned, but are signed by default
9184 * src/SDCCval.c (constVal): rearranged
9185 * src/SDCCval.c (valMod): preliminary fix
9186 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9228 constants are unsigned; added recognition of "u" flag for unsigned
9229 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9230 * src/SDCCval.c (valDiv, valMod): fixed signdness
9231 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9232 signedness of modulo, left and right shift

9638 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9639 the regression tests I'm not brave enough to enable 245.b, 245.c

9641 Using pdflatex this will give you a hyperlinked pdf file with
9642 bookmarks. (prepend '%' before /usepackage if this breaks something)

9691 * src/SDCCmain.c: linkOptions is changed to set *,
9692 added if/endif conditional macros to remove options help
9693 messages from optionsTable when a port is not configured, added
9694 support for the PIc16 port in the ports table, when executing
9695 the compiler with no port specified on command line, a default
9696 port is selected with the new macro DEFAULT_PORT which is
9697 defined in port.h, in setDefaultOptions() linkOptions is removed
9698 from initialization assignment, since now it is a set,
9699 parseCmdLine uses setParseWithComma for linkOptions, in
9700 linkEdit() linkOptions are accessed with new function indexSet()
9701 which returns the i'th item of a set variable. See SDCCset.c, in
9702 linkEdit() when calling buildCmdLine(), added linkOptions as
9703 last argument. Now users can pass arguments to gplink via the
9704 -Wl option, main() uses pic16glue() to glue up pic16 programs

9716 * src/pic16/glue.c: commented out some error producing lines
9717 * src/pic16/main.c: __config directives are commented out to stop
9718 gpasm complaining and test the linkage with gplink, _linkCmd and
9719 _asmCmd changed to be more gplink and gpasm friendly
9720 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9721 produced an error when parsed, peep rule 12 is added to utilize
9722 movff, but it is commented out since the pCode does not support
9723 yet a command with 2 address arguments
9725 2003-05-18 <johan AT balder>
9727 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9754 2003-05-11 Borut Razem <borut.razem AT siol.net>
9756 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9757 the path of bin directory, so that PATH is the only env. variable, which has to be set
9758 in case of standard installation.

10792 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10793 following files to include the previous two files: aslink.dsp,
10794 Makefile.aslink, Makefile.bcc, and Makefile.in.
10796 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
10797 .adb instead of .cdb
10799 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10801 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
10802 value from option --iram-size.
10804 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10806 * /sdcc/as/mcs51/lklist.c: added boundary check before using
10809 2002-09-18 <wiml AT hhhh.org>
10811 * SDCClrange.h: exposed setFromRange() and setToRange()
10812 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10813 packRegsForAccUse() (bug 542397)
10814 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10815 multiple times and emitting the fetch operations more than once
10816 added aopGetUsesAcc() function to allow binary operators to
10817 fetch their operands in the correct order; made genMinus() emit
10818 compact code for X = LITERAL - Y
10820 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10821 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
10822 sprintf() in line 1267.
10824 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10825 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10828 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10829 Changes to aslink (All the changes are marked with 'JCF'):
10831 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
10834 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
10835 area BSEG. Also moves, if possible, the DATA area down into the internal
10836 ram so more space is available.
10838 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
10841 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
10842 not bytes. Function summary() which creates a memory usage summary
10843 file with extension .mem. Reports of overlaping stack and small stack
10844 size. If the space for the stack is less than 16 bytes aslink trows a
10847 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
10848 the 8051. Option 'y' for memory summary output file.
10850 Changes to sdcc (All the changes are marked with 'JCF'):
10852 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
10854 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
10855 overlaying area for it (uses RegBankUsed[4]).
10857 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
10858 bank zero as used by default. By default aslink locates the stack
10859 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10860 the creation of the .mem file. Delegates the allocation of data area
10861 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10862 the begining of the stack area to aslink.
10864 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
10865 glue() in SDCCglue.c creates an area for it.
10867 2002-09-03 Borut Razem <borut.razem AT siol.net>
10868 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10869 sdcc/src/pic/glue.c:
10870 introduced atexit() handler for teporay files removal in case of
10871 errors, assertions, ...
10873 2002-08-29 Borut Razem <borut.razem AT siol.net>
10874 * sdcc/support/cpp2/auto-host_vc_in.h:
10875 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10876 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10877 Maybe there is a similar problem with BORLANDC? It should be checked!
10879 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10880 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10881 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10882 was not executed, and the compiler (cl) launched a warning:
10883 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10885 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10886 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10888 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10889 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10891 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10892 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10893 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10894 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10895 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10896 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10897 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10898 - added Release configuration in VS projects
10899 - review of compiler an linker options
10900 - VC .exe files are generated in bin_vc directory, not to interfere
10901 with binaries generated from other projects (cygwin, mingw, bcc ...)
10903 * sdcc/src/yacc.dsp: added
10905 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10906 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10907 and insert the version number definitions from .version
10909 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10911 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10912 added - genarate auto-host.h using auto-host_vc_in.h as template
10915 removed from CVS, generated automatically
10917 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10918 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10920 2002-08-11 Borut Razem <borut.razem AT siol.net>
10921 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10923 2002-08-10 Borut Razem <borut.razem AT siol.net>
10924 * src/SDCCmain.c (main):
10925 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10926 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10927 The consequence was that some temporary files were not removed.
10930 unification of code in functions tempfilename() and tempfile():
10931 function tempnam() is defined in Visual Studio 6.0 and .NET
10933 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10935 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10936 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10937 - removed compiler command line option /WX: Treats all warnings as errors
10938 - update a list of source files, included into the project
10940 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10941 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10942 changed project type to Generic Project so that can be correcly converted to VS.NET project
10944 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10946 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10948 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10950 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10951 added return 0 statements after assert() to make compiler happy
10953 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10954 added newline in the def file to keep MSC compiler satisfied
10956 * sdcc/src/z80/gen.c:
10957 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10958 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10959 - solved MSC error in function aopDump()
10961 * sdcc_vc.h: define PREFIX as "//sdcc"
10963 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10964 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10967 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10968 - Rewrote the register banking algorithm.
10969 - Added pCode live-range analysis to registers (for now, only non-used and
10970 singly-used registers optimized away)
10972 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10974 * 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.

11001 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11003 2002-03-28 Johan Knol <johan AT balder>
11005 * src/SDCCval.c: fixed bug #532436
11007 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11009 Added "char *Processor" field to the port structure.
11012 Added -p option. Allows port dependent processor to be specified.
11015 Initialized the new field char *Processor field to NULL in all ports
11018 Compiler generated registers for interrupt context saving
11019 were not getting allocated.
11021 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11024 Fixed left shift. Will promote the left side of a left shift
11025 if a) left shifting more than size of operand or b) when assigned
11026 to something size > size of left side
11028 2002-03-14 Scott Dattalo <scott AT dattalo.com>

11136 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11138 * sdcc/src/SDCCloop.c:
11139 Previous fix was not good. basic blocks that have "break" or "return" are
11140 not really partof a loop , but live ranges used in these blocks should
11141 be live thru the entire loop, so set partOfLoop but don't add them to
11144 2002-02-21 <johan AT FRIJA>
11146 * src/SDCCcse.c: fixed bug #514308
11148 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
