906 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
908 Enabled VPATH feature: changed nearly all Makefiles (149 files).
909 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
911 One basic decision: e.g. src/clean.mk includes further files. In order
912 to make this work there are two solutions:
913 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
914 run configure on them. This way they can use
915 'include $(srcdir)/port-clean.mk'
916 - always include clean.mk by the Makefile at the same level. To avoid
917 that `make clean` tries to include and build Makefile.dep the
918 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
919 implemented, because now even `make uninstall` doesn't create
920 Makefile.in. clean.mk could be eliminated by pasting it in
923 * debugger/mcs51/Makefile.in: build own objects from library sources
924 (SLIB, SDCC) in current directory
926 * configure, configure.in: renamed --disable-device-lib-build in
927 --disable-device-lib; added --enable-doc, the required tools are
928 searched by configure; added result message; the toolchain for the
929 belonging ports are now only built, if the port is enabled.
931 * support/regression/*: all output is written in directory gen, because
932 the fwk and ports directories don't livet in the build tree using vpath

1189 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
1191 * src/mcs51/gen.c (genCall): fixed bug 1457608
1193 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

1212 implemented patch 1120823 Thanks to Willy De la Court (normal
1213 interrupts need an interrupt number now if they are made critical),
1214 and enabled nesting of critical functions though not for gbz80
1215 (genCritical, genEndCritical): added functions
1216 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1217 * src/z80/mappings.i: added "ei" to all mappings

1226 2006-03-16 Raphael Neider <rneider AT web.de>
1228 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1229 the left operand is shorter than the result (c* = lit-c* + int),
1231 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1234 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1236 * src/.version: increased version number to 2.5.5
1237 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1238 linking is done manually in pic16 port's _linkEdit,
1239 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1240 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1241 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1242 allocate asmop as AOP_ACC,
1243 (aopForRemat): added parameter 'bool result' in function declaration,
1244 (pic16_aopGet): return AOP_ACC when accessing WREG,
1245 (pic16_popGetTempReg): minor modification,

1256 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1257 call to allocReg, not by manually allocating a new one,
1258 (pic16_assignRegisters): now before going through the register
1259 allocating functions mark all registers as free. This eliminates some
1260 side effects resulting from peephole parser done earlier in the backbone
1262 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1312 2006-03-06 Borut Razem <borut.razem AT siol.net>
1314 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1315 made the linker quiet
1317 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1319 * src/pic16/gen.c (genPcall): fixed bug #1443644
1320 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1321 which dumps before the function entry point a data byte which represents
1322 the number of the local variables used by the specified function, added
1323 'xinst' for initial support for Extended Instruction Support,
1324 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1325 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1326 port->fun_prefix anymore (may change later),
1327 (genFunction, genEndFunction): do not store/restore local registers for
1328 _main (this should take care the --main-return command line option in
1330 (genOr): removed some legacy pic-port instructions,
1331 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1332 performing operations with SFR's causes data to be written more than
1333 once to each SFR. Perhaps SFRs should be handled in special cases...
1334 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1336 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1337 into account for stack starting position,
1338 (struct OPTIONS pic16_optionsTable): added command line argument
1339 --extended or -y for Extended Instruction Support,
1340 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1341 (deassignLRs): *** perhaps the most important change, old 'for' code
1342 (commented out for reference), didn't account for some registers which
1343 were left marked 'not free' after a pointer operation. The change
1344 reduces register usage a lot in some cases
1346 2006-03-04 Borut Razem <borut.razem AT siol.net>
1348 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

1354 2006-03-03 Borut Razem <borut.razem AT siol.net>
1356 * support/regression/fwk/lib/testfwk.c,
1357 support/regression/fwk/include/testfwk.h: introduced function

3620 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3621 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3622 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3623 always available in leading double underscore form. The C99 support is
3624 mostly missing, but it's a start.
3625 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3626 reserved identifier "__data".

3704 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3706 * device/lib/printf_large.c: removed inline assembly for portability and
3707 readability. Use printf_fast if speed or size are more important.
3708 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3709 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3711 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3713 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3714 prevent compiler warning
3716 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3718 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3719 moved to level 0 and declared as static. Also they are explicit
3720 placed in access bank. This was necessery because some times they
3721 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3722 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3723 optimizations. Currently only compare to unsigned char is implemented,
3724 * src/pic16/gen.c: added fReturnIdx array,
3725 * (struct resolvedIfx) is moved to gen.h and made public,
3726 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3727 * (aopForSym): added an optimization to directly store in stack of
3728 the operand of a SEND iCode,
3729 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3730 but as registers instead (AOP_REG) using the fReturnIdx array,
3731 * (pic16_freeAsmop): remove the freed register from the
3732 _G.sregsAlloc field,
3733 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3734 a compare of 'WREG',
3735 * (pic16_popGetTempRegCond): changed function prototype, now
3736 function takes also a bitVector argument v which holds the current
3737 set of registers that are allocated for stack access by aopForSym,
3738 registers allocated in aopForSym for accessing stack symbols are not
3739 any more part of the functions usedRegs field,
3740 * (genCall): some times aopOp is called for a stack variable to be
3741 send, aopForSym might perform the push, if this is true make sure
3742 that genCall doesn't push the variable twice by testing _G.resDirect,
3743 * (genFunction): changed testing for unspecified interrupt number
3744 from 256 to INTNO_UNSPEC,
3745 * modified selection scheme of frame pointer generation. Previously
3746 if function did use local registers a frame pointer was generated,
3747 now a frame pointer is generated only if function has arguments
3748 (that need PLUSW2 register access), or has stack arguments, or the
3749 compiler is not instructed to omit the frame pointer,
3750 * (genEndFunction): before restoring local registers that were saved
3751 in the function preamble, also restore the registers that *might*
3752 have been allocated for stack access,
3753 * (genRet): removed some old comments,
3754 * (genCmp, the active (RN's) version): added a call to the
3755 pic16_genCmp_special function to perform the compare with a more
3756 robust and optimized way,
3757 * (genInline): a feature has been added in inline code generation,
3758 which allows a wildcard variable substitution when writing inline
3759 assembly. Code is incomplete and experimental therefore undocumented,
3760 * (genCast): changed order of aopOp for result and right to allow
3761 aopForSym to directly load the result if possible,
3762 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3763 perform an optimized compare on some selected special occasions,
3764 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3765 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3766 generate an IVT any more,
3767 * src/pic16/main.c (pic16_optionsTable): added command line option
3769 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3770 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3772 * src/pic16/NOTES: Raphael Neider added in list of active developers
3773 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3774 jumptable_end to prevent bug #,
3775 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3776 inCond and outCond fields,
3777 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3778 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3779 turn off register spilling,
3780 * (packRegsForOneUse): synced with other ports' versions although it
3781 is not used currently,
3782 * (pic16_packRegisters): added an optimization while reading
3783 structure bitfields, some registers may be saved (malloc code is
3784 decreased by 80 bytes)
3786 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3788 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3789 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3790 this can be optimized more?
3792 2005-03-10 Raphael Neider <rneider AT web.de>
3794 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3795 genNearPointerGet): (hopefully) fixed access to bitfields via
3796 pointers (p->bitN = x; and x = p->bitN; failed)

4430 Adding support for replacing ljmps with sjmps in jumptables
4431 generated for switch statements. For now you need to set the
4432 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4433 Now 4 algorithms for mcs51 jumptable generation are used:
4434 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4435 addresses loaded pc-relative for up to 112 cases and stack-pushing
4436 target addresses loaded with offset from dptr for up to 256 cases.

4463 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4464 to call when a stack overflow occurs,
4465 * (malloc.h): added CVS Id tag,
4466 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4468 * added libc directory. The current version of LibC contains string
4469 functions, ctype functions and macros and some functions of the
4470 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4471 be extensively tested in the future. Standard disclaimer here.
4472 Library is not automatically build yet. But one can build it by
4473 invoking 'make' inside the libc directory.
4474 * added ADC library under libio. Preliminary version yet.

4484 * (pic16_storeForReturn): optimized return of 0,
4485 * (genCmp): experimental code for new genCmp which uses PIC18's
4486 special compare&skip instructions. Initial tests fail some times
4487 with variables grater than 1 byte in size, so new code is disabled,
4488 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4490 * (genCast): began a fix to optimize the casting of a bit to another
4491 bit, now assigning a bitfield to another bitfield will fail, sorry,
4492 * src/pic16/main.c: disabled the use of lr-support feature,
4493 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4496 bits with offset (case PO_GPR_BIT),
4497 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4499 * (isBankInstruction): modified to return 0 for no banking instruction,
4500 and 1 for banking instruction,
4501 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4502 caused stop processing pCodes after a inline assembly block,
4503 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4504 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4505 registers when it shouldn't,
4506 * src/pic16/ralloc.c (allocReg): add preliminary support for
4507 supporting a limited set of temporary registers,
4509 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4511 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

4514 (loadRegFromAop): recognize CLRH optimization,
4515 (genFunction): optimize RECEIVE iCodes in reentrant functions
4517 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7420 * support/regression/generate-cases.py (main): Changed from inline
7423 * doc/Makefile (install): Changed to depth first to get rid of
7424 missing directory install warning.
7426 * as/Makefile (install-doc): Made work on Mac.
7428 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
7430 * src/SDCCast.c: added an additional type flow in decorateType() of
7431 opposite direction, see feature request #860006; it's enabled at runtime
7432 by setting the environment variable SDCC_NEWTYPEFLOW
7433 * src/SDCCast.h: changed prototype of decorateType()
7434 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
7435 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
7436 'char' to 'int' can be omitted, if both operands are 'unsigned char';
7437 see feature request #877103
7438 * src/SDCCval.c: updated call of decorateType()
7439 (valBitwise): fixed bug #882876
7440 (valMinus): added promotion
7441 (valLogicAndOr): result is unsigned
7442 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
7443 * src/SDCCsymt.c (computeType),
7444 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
7445 must not cause an unsigned operation
7446 * src/pic/glue (pic14emitRegularMap),
7447 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
7449 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>

7466 * src/pic/ralloc.h: applied patch from Slade Rich;
7467 added support for multiple code pages and multiple RAM banks on the
7468 PIC 14 port. The ASM files now no longer simply assume all the
7469 code / RAM are in the same page / bank. This means the linker can
7470 safely allocate code/RAM of separate ASM files to different pages/banks.
7471 * doc/sdccman.lyx: added Slade's tips
7472 * src/mcs51/peeph.def: fixed bug #880768

7481 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
7484 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
7485 strtof is not part of C89 and isn't included with Mac OS X.
7487 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7489 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

7514 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7516 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7517 loaded with the linker search paths (-L arguments) and the libraries
7518 to be linked with the current source (-l arguments). Changes
7519 currently will affect only the pic16 port.
7520 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7521 include path the port specific paths and port specific libraries,
7522 * gplink command now contains the $3 argument,
7523 * src/pic16/device.h,
7524 * src/pic16/device.c,: structure PIC_device is made public and
7525 renamed to PIC16_device, the same for variable Pics which is renamed

7540 Documenting changes from previous commits.
7541 * configure.in (version 1.56),
7542 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7543 when generating output files to configure the pic16 library,
7544 but now I've commented it out, since gputils aren't installed in the
7545 SF compile farm, so library won't compile
7547 * device/lib/Makefile.in (version 1.56): initially I've added in
7548 target 'all' the prerequestive 'model-pic16' so it compiled the
7549 pic16 library, but now I've commented it out for the same reasons
7551 * added targets 'model-pic16' and 'objects-pic16' to compile the
7553 * added target 'port-specific-objects-pic16' to handle the
7554 generated libraries and copy them into the build/ directory
7555 * added target 'clean-intermediate-pic16' to clean intermediate
7556 files into pic16 directory
7557 * in target 'installdirs' added line to create directory pic16 in
7558 the installation path
7560 * device/include/Makefile.in (version 1.11): in target 'install'
7561 added lines to copy all header files to installation path,
7562 * in target 'installdirs' added line create directory for pic16
7563 headers in the installation path

7578 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7579 option so that it actually works. Made it specific to the z80, since
7580 the gbz80 doesn't have these kinds of I/O ports.
7582 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7584 * device/include/z180.h,

7606 Mainly changes to support compilation of the device libraries
7607 * src/pic16/device.c: stack is allocated via symbol and not
7608 via literal number. The symbol is placed in the corresponding
7609 position of the data ram
7610 * (pic16_dump_section): relocatable and absolute uninitialized
7611 data are now emitted in sorted order to reduce section naming,
7612 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7613 weren't marked as being in the access bank,
7615 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7617 Added portion of GNU PIC Library under the directory
7618 device/include/pic16 and device/lib/pic16. These files
7619 contain the declarations of SFRs for the PIC18Fxx2 devices.
7620 The directory is initialized via configure from toplevel.
7622 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

7650 all over. Telling LaTeX to be less strict with word spacing
7651 to better keep the right margin. Changed some notes about
7652 maintainance of the ports in section 3.2.1 - is it OK like this?
7654 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7694 * src/pic16/peeph.def: all peepholes with movff are commented out,
7695 because there is a problem in the pcode peep optimizer,
7696 * src/pic16/ralloc.c: the register allocator can now reuse local

7848 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7850 PIC16 port related changes:
7851 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7852 added variable stackPos,
7854 * gen.c: genCall, assignResultValue: added support for
7855 pushing/retrieving function parameters to/from stack,
7856 genFunction,genEndFunction: setup stack frame for the
7858 genAddrOf: will be changed according to bug 863624
7860 * added files genutils.c and genutils.h which contain gen*
7861 debugged and optimised functions extracted from gen.c
7863 * glue.c: added variable 'externs' which holds extern symbols,
7864 pic16emitRegularMap: is modified to properly handle relocatable
7865 symbols under the new scheme,
7866 pic16createInterruptVect: is modified
7867 pic16printPublics: is modified to emit 'global' assembler directives,
7868 added pic16_printExterns to print extern symbols,
7869 pic16glue: initializes stack/frame pointer in the beginning of
7870 the assembly output. Temporary hack, will be corrected later,
7871 because gplink yet does not support stack and SDCC does not
7872 yet support a type of crt0.o object to create the final binary.
7874 * Removed many lines that contain 8051 legacy code.
7875 * The code is finally placed under a 'code' directive.
7876 * Added port specific options.
7878 * _process_pragma: simplified since now we do not need *special*
7879 include file to define SFR registers. But a separate header
7880 will be needed. This will be developed later.
7881 * _pic16_parseOptions: added, parses port specific options:
7882 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7883 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7884 --preplace-udata-with=
7886 * _pic16_setDefaultOptions: modified to initialize section names,
7887 but hack is temporarly out of order since it needs improvement.
7888 * _pic16_genAssemblerPreamble: configuration words are emitted by
7889 their address instead of their name. This part is incomplete and
7890 supports only the 18Fxx2 devices. Other devices will emit an error
7891 during assembly since they do not contain the same set of config
7893 * _pic16_genIVT: is modified,
7895 * pcode.c: added definitions for some hardware registers that are needed
7897 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7898 All PCI entries are updated. Now LFSR is supported.
7899 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7900 * added pic16_newpCodeOpLit2 to support instructions with
7901 two literal arguments
7902 * pic16_pCode2str: corrected code that emits assembler instructions
7903 with two literal operands and those that have an access bit modifier
7904 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7905 this fixes a bug which caused some labels to be lost, when an
7906 assembler directive was added, i.e. banksel,
7907 * pic16_FixRegisterBanking: improved logic that causes the insertion
7909 * InlineFunction: functions that are called once, are not any more
7910 inlined. This can be a port option in the future,
7912 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7914 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7915 hold the corresponding uninitialized symbols,
7916 * pic16_allocProcessorRegister: registers have explicit marked the
7918 * pic16_allocInternalRegister: registers are explicit marked as
7920 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7921 processing list, so bit registers were lost,
7924 * ralloc.h: added field 'accessBank' and original symbol operand
7925 in register definition,
7926 * removed the field isMapped from register definition,
7928 ** Several functions have been removed from various sources:
7929 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7930 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7931 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7932 pic16_assignRelocatableRegisters
7934 ** others have been introduced:
7935 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7936 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7938 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7940 * support/scripts/inc2h.pl: changed definition of BIT_AT
7941 to emit 'sbit at' instead of 'bit at'. This was a request.
7943 PIC16 port related preliminary changes:
7944 * gen.c: prefixed function popRegFromString with
7945 pic16_ and all references to it corrected
7946 * pcode.c: all pic16_pc_* hardware registers prefixed
7947 with underscore (_),
7948 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7949 * ralloc.c: newReg(): when register is REG_SFR then
7950 set address to rIdx,
7951 pic16_allocProcessorRegister(): marks register wasUsed=0
7952 pic16_writeUsedRegs(): added a call to assign processor
7953 registers via pic16_assignFixedRegisters
7955 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7957 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7958 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7959 variables in unused register banks. Also the SSEG is placed
7960 wherever there is enough space for it, and IDATA can be anywhere
7961 in internal RAM. For now compile using -Wl-Y[stack_size].
7962 The mem file is different for this option as well, since it
7963 makes no sense of talking about DSEG lenght.
7965 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7967 * src/SDCClrange.c: fixed bug 869095 that caused segfault

8212 * src/SDCCast.c (decorateType): disabled a transformation I added in
8213 revision 1.188 (access to fields of a structure at an absolute address);
8214 it breaks with bitfields, extern declarations, and gcse analysis.
8215 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8216 could be assigned through a pointer, so don't complain.

8973 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8974 fetching of the pointer
8975 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8976 copied from genNearPointerSet()
8977 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8978 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

8992 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8994 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8995 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8996 type for bits was changed. It resulted in bit variables becoming
8997 global, which is not permitted in PIC 14 assembly output.
8999 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9001 * doc/sdccman.lyx: various additions and updates. Rearranged sections
9003 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9005 Z80 and MCS51 linkers complaint if a public symbol is defined

9014 A few small changes that speed up the peephole optimizer.
9018 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9020 Try to make the peephole optimizer smarter by maintaining
9021 an association between the assembly source code and the
9022 iCodes that originated them. Put this information to use
9023 with a new peephole rule condition "notVolatile" so that
9024 the rules can be aggressive yet still safe.
9029 * src/mcs51/peeph.def
9031 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9035 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9036 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9037 if the left or right operand symbols have the accuse flag set.
9039 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9041 Changed the type of the result of the ! (NOT) operator to char;
9042 previously it returned the same type as the source. This allows
9043 us to eliminate all the genFloatNot functions (all of its target
9044 implementations were very buggy) since !float can use the same
9047 * src/SDCCicode.c (ast2iCode): ! returns char
9048 * src/mcs51/gen.c (genNot, genNotFloat),
9049 * src/ds390/gen.c (genNot, genNotFloat),
9050 * src/z80/gen.c (genNot, genNotFloat),
9051 * src/pic/gen.c (genNot, genNotFloat),

9056 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9057 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9058 during interrupts. Ensure WSAVE is located at a shared bank address.
9059 2. Fixed page selection in some places
9060 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9061 the registers name strings.
9062 4. Fixed "signed / unsigned compare" compiler warnings.
9063 5. The PIC port manages its own allocation of the general purpose
9064 registers, but makes no attempt to reuse them. As a result when
9065 compiling it soon runs out of general purpose registers. Some
9066 additional code was added to the files pcode.c and device.c to walk
9067 through the function call tree and rename the registers so that they
9077 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9078 genPlus() & genMinus() when the result is the same as left or right

9084 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9086 Made bitfield a distinct type from bit so that bitfields
9087 convert as per ANSI C and bits retain their traditional
9088 boolean style behaviour. Implemented bitfield support in
9096 * src/ds390/gen.c: bit v bitfield split
9097 * src/z80/gen.c: New support for bitfields
9098 * support/regression/tests/bitfields.c: reenabled z80,
9101 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9103 Rules 246.x, 247.x relate to bitfields, the others speed up
9104 access to xdata mapped I/O devices.
9106 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9108 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9110 Cleaned up genPackBits and genUnpackBits and added two helper
9111 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9112 for literal assignments in genPackBits (thanks to Frieder for
9118 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9120 Fixed bug #748310 (pointer to function type mishandled when the
9121 function name is omitted). Also fixed a SIGSEGV when a function
9122 attribute (reentrant, etc) is used on a non-function or on a
9123 function but misplaced before the parameter list.
9125 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9127 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

9150 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9152 Made the constant following the "interrupt" keyword optional. If
9153 omitted, the function will not automatically be given an entry
9154 in the interrupt vector table (similar to #pragma NOIV, but
9155 less syntacticly kludgy). The interrupt number is also now
9156 range checked. Also fixed a bug in the high order bit example

9170 * src/SDCCicode.c (operandOperation): rewritten some ops
9171 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9172 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9174 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9175 be re-activated by defining REDUCE_LITERALS)
9176 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9177 unsigned, but are signed by default
9178 * src/SDCCval.c (constVal): rearranged
9179 * src/SDCCval.c (valMod): preliminary fix
9180 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9632 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9633 the regression tests I'm not brave enough to enable 245.b, 245.c
9634 * doc/sdccman.lyx: added latex preamble for hyperref package.
9635 Using pdflatex this will give you a hyperlinked pdf file with
9636 bookmarks. (prepend '%' before /usepackage if this breaks something)

9674 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9676 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9677 it can be defined with CFLAGS when running configure
9678 * src/SDCCmain.c: fixed compiling + linking with object files
9680 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

9683 added --disable-pic16-port
9684 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9685 * src/SDCCmain.c: linkOptions is changed to set *,
9686 added if/endif conditional macros to remove options help
9687 messages from optionsTable when a port is not configured, added
9688 support for the PIc16 port in the ports table, when executing
9689 the compiler with no port specified on command line, a default
9690 port is selected with the new macro DEFAULT_PORT which is
9691 defined in port.h, in setDefaultOptions() linkOptions is removed
9692 from initialization assignment, since now it is a set,
9693 parseCmdLine uses setParseWithComma for linkOptions, in
9694 linkEdit() linkOptions are accessed with new function indexSet()
9695 which returns the i'th item of a set variable. See SDCCset.c, in
9696 linkEdit() when calling buildCmdLine(), added linkOptions as
9697 last argument. Now users can pass arguments to gplink via the
9698 -Wl option, main() uses pic16glue() to glue up pic16 programs

9710 * src/pic16/glue.c: commented out some error producing lines
9711 * src/pic16/main.c: __config directives are commented out to stop
9712 gpasm complaining and test the linkage with gplink, _linkCmd and
9713 _asmCmd changed to be more gplink and gpasm friendly
9714 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9715 produced an error when parsed, peep rule 12 is added to utilize
9716 movff, but it is commented out since the pCode does not support
9717 yet a command with 2 address arguments
9719 2003-05-18 <johan AT balder>
9721 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9748 2003-05-11 Borut Razem <borut.razem AT siol.net>
9750 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9751 the path of bin directory, so that PATH is the only env. variable, which has to be set
9752 in case of standard installation.
9753 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10795 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
10796 value from option --iram-size.
10798 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10800 * /sdcc/as/mcs51/lklist.c: added boundary check before using
10803 2002-09-18 <wiml AT hhhh.org>
10805 * SDCClrange.h: exposed setFromRange() and setToRange()
10806 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10807 packRegsForAccUse() (bug 542397)
10808 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10809 multiple times and emitting the fetch operations more than once
10810 added aopGetUsesAcc() function to allow binary operators to
10811 fetch their operands in the correct order; made genMinus() emit
10812 compact code for X = LITERAL - Y
10814 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10815 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
10816 sprintf() in line 1267.
10818 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10819 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10822 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10823 Changes to aslink (All the changes are marked with 'JCF'):
10825 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
10828 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
10829 area BSEG. Also moves, if possible, the DATA area down into the internal
10830 ram so more space is available.
10832 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
10835 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
10836 not bytes. Function summary() which creates a memory usage summary
10837 file with extension .mem. Reports of overlaping stack and small stack
10838 size. If the space for the stack is less than 16 bytes aslink trows a
10841 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
10842 the 8051. Option 'y' for memory summary output file.
10844 Changes to sdcc (All the changes are marked with 'JCF'):
10846 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
10848 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
10849 overlaying area for it (uses RegBankUsed[4]).
10851 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
10852 bank zero as used by default. By default aslink locates the stack
10853 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10854 the creation of the .mem file. Delegates the allocation of data area
10855 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10856 the begining of the stack area to aslink.
10858 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
10859 glue() in SDCCglue.c creates an area for it.
10861 2002-09-03 Borut Razem <borut.razem AT siol.net>
10862 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10863 sdcc/src/pic/glue.c:
10864 introduced atexit() handler for teporay files removal in case of
10865 errors, assertions, ...
10867 2002-08-29 Borut Razem <borut.razem AT siol.net>
10868 * sdcc/support/cpp2/auto-host_vc_in.h:
10869 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10870 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10871 Maybe there is a similar problem with BORLANDC? It should be checked!
10873 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10874 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10875 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10876 was not executed, and the compiler (cl) launched a warning:
10877 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10879 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10880 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10882 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10883 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10885 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10886 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10887 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10888 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10889 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10890 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10891 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10892 - added Release configuration in VS projects
10893 - review of compiler an linker options
10894 - VC .exe files are generated in bin_vc directory, not to interfere
10895 with binaries generated from other projects (cygwin, mingw, bcc ...)
10897 * sdcc/src/yacc.dsp: added
10899 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10900 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10901 and insert the version number definitions from .version
10903 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10905 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10906 added - genarate auto-host.h using auto-host_vc_in.h as template
10909 removed from CVS, generated automatically
10911 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10912 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10914 2002-08-11 Borut Razem <borut.razem AT siol.net>
10915 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10917 2002-08-10 Borut Razem <borut.razem AT siol.net>
10918 * src/SDCCmain.c (main):
10919 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10920 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10921 The consequence was that some temporary files were not removed.
10924 unification of code in functions tempfilename() and tempfile():
10925 function tempnam() is defined in Visual Studio 6.0 and .NET
10927 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10929 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10930 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10931 - removed compiler command line option /WX: Treats all warnings as errors
10932 - update a list of source files, included into the project
10934 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10935 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10936 changed project type to Generic Project so that can be correcly converted to VS.NET project
10938 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10940 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10942 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10944 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10945 added return 0 statements after assert() to make compiler happy
10947 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10948 added newline in the def file to keep MSC compiler satisfied
10950 * sdcc/src/z80/gen.c:
10951 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10952 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10953 - solved MSC error in function aopDump()
10955 * sdcc_vc.h: define PREFIX as "//sdcc"
10957 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10958 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10964 singly-used registers optimized away)
10966 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10968 * 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.

10993 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
10995 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10997 2002-03-28 Johan Knol <johan AT balder>
10999 * src/SDCCval.c: fixed bug #532436
11001 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11003 Added "char *Processor" field to the port structure.
11006 Added -p option. Allows port dependent processor to be specified.
11009 Initialized the new field char *Processor field to NULL in all ports
11012 Compiler generated registers for interrupt context saving
11013 were not getting allocated.
11015 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11018 Fixed left shift. Will promote the left side of a left shift
11019 if a) left shifting more than size of operand or b) when assigned
11020 to something size > size of left side
11022 2002-03-14 Scott Dattalo <scott AT dattalo.com>

11026 analysis is restructured. ...
11028 * src/pic/device.h:
11031 * src/pic/device.c:
11032 Added. device.c is a PIC port hack to accomodate variations
11035 2002-03-13 Michael Hope <michaelh AT vroom>
11037 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11039 2002-03-04 johanknol <johanknol AT manik>
11041 * /src/SDCCval.c: fixed
11043 const unsigned char arr[][2] = { { 0, 1 } };

11130 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11132 * sdcc/src/SDCCloop.c:
11133 Previous fix was not good. basic blocks that have "break" or "return" are
11134 not really partof a loop , but live ranges used in these blocks should
11135 be live thru the entire loop, so set partOfLoop but don't add them to
11138 2002-02-21 <johan AT FRIJA>
11140 * src/SDCCcse.c: fixed bug #514308
11142 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

11146 statement inside a loop, it was not being considered part of the loop.
11148 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
11150 2002-02-10 Karl Bongers <karl AT turbobit.com>
