189 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
191 Enabled VPATH feature: changed nearly all Makefiles (149 files).
192 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
194 One basic decision: e.g. src/clean.mk includes further files. In order
195 to make this work there are two solutions:
196 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
197 run configure on them. This way they can use
198 'include $(srcdir)/port-clean.mk'
199 - always include clean.mk by the Makefile at the same level. To avoid
200 that `make clean` tries to include and build Makefile.dep the
201 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
202 implemented, because now even `make uninstall` doesn't create
203 Makefile.in. clean.mk could be eliminated by pasting it in
206 * debugger/mcs51/Makefile.in: build own objects from library sources
207 (SLIB, SDCC) in current directory
209 * configure, configure.in: renamed --disable-device-lib-build in
210 --disable-device-lib; added --enable-doc, the required tools are
211 searched by configure; added result message; the toolchain for the
212 belonging ports are now only built, if the port is enabled.
214 * support/regression/*: all output is written in directory gen, because
215 the fwk and ports directories don't livet in the build tree using vpath
217 * doc/sdccman.lyx: renamed --disable-device-lib-build to
218 --disable-device-lib, added --enable-doc, added section VPATH
220 * sim/ucsim/configure.in,
221 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
222 z80 are enabled by default
224 2006-04-24 Raphael Neider <rneider AT web.de>
226 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
227 to config word, "pic14_"-prefixed some extern functions
228 (pic14_emitConfigWord): emit __config directive(s) if assignment to
229 config word has been found
230 * src/pic/device.h: added prototypes
231 * src/pic/pcode.c: added "pic14_"-prefix where needed
232 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
234 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

248 fixes #1469504 and #1474602,
249 (pCodeRegOptimizeRegUsage): fixed typo in comment

494 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
495 implemented patch 1120823 Thanks to Willy De la Court (normal
496 interrupts need an interrupt number now if they are made critical),
497 and enabled nesting of critical functions though not for gbz80
498 (genCritical, genEndCritical): added functions
499 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
500 * src/z80/mappings.i: added "ei" to all mappings
502 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

505 submitted by the Debian SDCC maintainer Aurelien Jarno:
506 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
507 archive with gcc 4.1 on mips and wrote the patch"
509 2006-03-16 Raphael Neider <rneider AT web.de>
511 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
512 the left operand is shorter than the result (c* = lit-c* + int),
514 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
517 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
519 * src/.version: increased version number to 2.5.5
520 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
521 linking is done manually in pic16 port's _linkEdit,
522 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
523 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
524 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
525 allocate asmop as AOP_ACC,
526 (aopForRemat): added parameter 'bool result' in function declaration,
527 (pic16_aopGet): return AOP_ACC when accessing WREG,
528 (pic16_popGetTempReg): minor modification,
529 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
530 'pic16_allocWithIdx',
531 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
532 calling function in absolute addresses,
533 (genAssign): take into account AOP_ACC asmop,
534 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
535 * src/pic16/pcoderegs.c: some debug functions and lines added,

537 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
539 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
540 call to allocReg, not by manually allocating a new one,
541 (pic16_assignRegisters): now before going through the register
542 allocating functions mark all registers as free. This eliminates some
543 side effects resulting from peephole parser done earlier in the backbone
545 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
547 * src/SDCCicode.c (geniCodeLogic),

566 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
567 (aopForSym, aopOp): increment asmop.allocated if reused,
568 (freeAsmop): decrement asmop.allocated and check for zero instead of
570 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
571 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,

603 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
604 which dumps before the function entry point a data byte which represents
605 the number of the local variables used by the specified function, added
606 'xinst' for initial support for Extended Instruction Support,
607 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
608 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
609 port->fun_prefix anymore (may change later),
610 (genFunction, genEndFunction): do not store/restore local registers for
611 _main (this should take care the --main-return command line option in
613 (genOr): removed some legacy pic-port instructions,
614 * src/pic16/genarith.c (genAddLit): re-enabled old code because
615 performing operations with SFR's causes data to be written more than
616 once to each SFR. Perhaps SFRs should be handled in special cases...
617 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
619 * src/pic16/main.c (_process_pragma): stack bound checking did not take
620 into account for stack starting position,
621 (struct OPTIONS pic16_optionsTable): added command line argument
622 --extended or -y for Extended Instruction Support,
623 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
624 (deassignLRs): *** perhaps the most important change, old 'for' code
625 (commented out for reference), didn't account for some registers which
626 were left marked 'not free' after a pointer operation. The change
627 reduces register usage a lot in some cases

2985 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2987 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2989 * device/lib/printf_large.c: removed inline assembly for portability and
2990 readability. Use printf_fast if speed or size are more important.
2991 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2992 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2994 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2996 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2997 prevent compiler warning
2999 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3001 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3002 moved to level 0 and declared as static. Also they are explicit
3003 placed in access bank. This was necessery because some times they
3004 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3005 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3006 optimizations. Currently only compare to unsigned char is implemented,
3007 * src/pic16/gen.c: added fReturnIdx array,
3008 * (struct resolvedIfx) is moved to gen.h and made public,
3009 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3010 * (aopForSym): added an optimization to directly store in stack of
3011 the operand of a SEND iCode,
3012 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3013 but as registers instead (AOP_REG) using the fReturnIdx array,
3014 * (pic16_freeAsmop): remove the freed register from the
3015 _G.sregsAlloc field,
3016 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3017 a compare of 'WREG',
3018 * (pic16_popGetTempRegCond): changed function prototype, now
3019 function takes also a bitVector argument v which holds the current
3020 set of registers that are allocated for stack access by aopForSym,
3021 registers allocated in aopForSym for accessing stack symbols are not
3022 any more part of the functions usedRegs field,
3023 * (genCall): some times aopOp is called for a stack variable to be
3024 send, aopForSym might perform the push, if this is true make sure
3025 that genCall doesn't push the variable twice by testing _G.resDirect,
3026 * (genFunction): changed testing for unspecified interrupt number
3027 from 256 to INTNO_UNSPEC,
3028 * modified selection scheme of frame pointer generation. Previously
3029 if function did use local registers a frame pointer was generated,
3030 now a frame pointer is generated only if function has arguments
3031 (that need PLUSW2 register access), or has stack arguments, or the
3032 compiler is not instructed to omit the frame pointer,
3033 * (genEndFunction): before restoring local registers that were saved
3034 in the function preamble, also restore the registers that *might*
3035 have been allocated for stack access,
3036 * (genRet): removed some old comments,

3038 pic16_genCmp_special function to perform the compare with a more
3039 robust and optimized way,
3040 * (genInline): a feature has been added in inline code generation,
3041 which allows a wildcard variable substitution when writing inline
3042 assembly. Code is incomplete and experimental therefore undocumented,
3043 * (genCast): changed order of aopOp for result and right to allow
3044 aopForSym to directly load the result if possible,

3713 Adding support for replacing ljmps with sjmps in jumptables
3714 generated for switch statements. For now you need to set the
3715 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3716 Now 4 algorithms for mcs51 jumptable generation are used:
3717 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3718 addresses loaded pc-relative for up to 112 cases and stack-pushing
3719 target addresses loaded with offset from dptr for up to 256 cases.

3749 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3751 * added libc directory. The current version of LibC contains string
3752 functions, ctype functions and macros and some functions of the
3753 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3754 be extensively tested in the future. Standard disclaimer here.
3755 Library is not automatically build yet. But one can build it by

3767 * (pic16_storeForReturn): optimized return of 0,
3768 * (genCmp): experimental code for new genCmp which uses PIC18's
3769 special compare&skip instructions. Initial tests fail some times
3770 with variables grater than 1 byte in size, so new code is disabled,
3771 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3773 * (genCast): began a fix to optimize the casting of a bit to another
3774 bit, now assigning a bitfield to another bitfield will fail, sorry,

3783 and 1 for banking instruction,
3784 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3785 caused stop processing pCodes after a inline assembly block,
3786 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

3788 registers when it shouldn't,
3789 * src/pic16/ralloc.c (allocReg): add preliminary support for
3790 supporting a limited set of temporary registers,
3792 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3798 (genFunction): optimize RECEIVE iCodes in reentrant functions
3800 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6800 loaded with the linker search paths (-L arguments) and the libraries
6801 to be linked with the current source (-l arguments). Changes
6802 currently will affect only the pic16 port.
6803 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6804 include path the port specific paths and port specific libraries,
6805 * gplink command now contains the $3 argument,
6806 * src/pic16/device.h,
6807 * src/pic16/device.c,: structure PIC_device is made public and

6823 Documenting changes from previous commits.
6824 * configure.in (version 1.56),
6825 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6826 when generating output files to configure the pic16 library,
6827 but now I've commented it out, since gputils aren't installed in the
6828 SF compile farm, so library won't compile
6830 * device/lib/Makefile.in (version 1.56): initially I've added in
6831 target 'all' the prerequestive 'model-pic16' so it compiled the
6832 pic16 library, but now I've commented it out for the same reasons
6834 * added targets 'model-pic16' and 'objects-pic16' to compile the
6836 * added target 'port-specific-objects-pic16' to handle the
6837 generated libraries and copy them into the build/ directory
6838 * added target 'clean-intermediate-pic16' to clean intermediate
6839 files into pic16 directory
6840 * in target 'installdirs' added line to create directory pic16 in

7085 * src/SDCCast.c (decorateType),
7086 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
7087 LEFT_OP (left shift)
7089 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7091 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7092 (default behaviour).
7094 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7096 A python script to validate compiler diagnostic messages. It can be
7097 used to verify that sdcc complains about bad c source code and
7098 gives a good location of the error.
7099 * support/valdiag/Makefile,
7100 * support/valdiag/valdiag.py,
7101 * support/valdiag/tests/*
7103 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7116 * src/common.h: added ifndef/define/endif macros
7117 around the header file.
7118 Bug reported from Jesus Calvino-Fraga
7120 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7122 * sdcc.spec: updated
7123 * device/include/Makefile.in: don't install CVS directories
7124 * device/lib/Makefile.in: added removal of CVS directories after install
7125 * doc/Makefile: fixed install, added local_icons
7126 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7127 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7128 * src/ds390/gen.c (genRightShift): fixed bug #870788
7129 * src/SDCCast.c (decorateType): fixed bug #870781
7131 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7133 PIC16 port related changes:
7134 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7135 added variable stackPos,
7137 * gen.c: genCall, assignResultValue: added support for
7138 pushing/retrieving function parameters to/from stack,
7139 genFunction,genEndFunction: setup stack frame for the
7141 genAddrOf: will be changed according to bug 863624
7143 * added files genutils.c and genutils.h which contain gen*
7144 debugged and optimised functions extracted from gen.c
7146 * glue.c: added variable 'externs' which holds extern symbols,
7147 pic16emitRegularMap: is modified to properly handle relocatable
7148 symbols under the new scheme,
7149 pic16createInterruptVect: is modified
7150 pic16printPublics: is modified to emit 'global' assembler directives,
7151 added pic16_printExterns to print extern symbols,
7152 pic16glue: initializes stack/frame pointer in the beginning of
7153 the assembly output. Temporary hack, will be corrected later,
7154 because gplink yet does not support stack and SDCC does not
7155 yet support a type of crt0.o object to create the final binary.
7157 * Removed many lines that contain 8051 legacy code.
7158 * The code is finally placed under a 'code' directive.
7159 * Added port specific options.
7161 * _process_pragma: simplified since now we do not need *special*
7162 include file to define SFR registers. But a separate header
7163 will be needed. This will be developed later.
7164 * _pic16_parseOptions: added, parses port specific options:
7165 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7166 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7167 --preplace-udata-with=
7169 * _pic16_setDefaultOptions: modified to initialize section names,
7170 but hack is temporarly out of order since it needs improvement.
7171 * _pic16_genAssemblerPreamble: configuration words are emitted by
7172 their address instead of their name. This part is incomplete and
7173 supports only the 18Fxx2 devices. Other devices will emit an error
7174 during assembly since they do not contain the same set of config
7176 * _pic16_genIVT: is modified,
7178 * pcode.c: added definitions for some hardware registers that are needed
7180 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7181 All PCI entries are updated. Now LFSR is supported.
7182 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7183 * added pic16_newpCodeOpLit2 to support instructions with
7184 two literal arguments
7185 * pic16_pCode2str: corrected code that emits assembler instructions
7186 with two literal operands and those that have an access bit modifier
7187 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7188 this fixes a bug which caused some labels to be lost, when an
7189 assembler directive was added, i.e. banksel,
7190 * pic16_FixRegisterBanking: improved logic that causes the insertion
7192 * InlineFunction: functions that are called once, are not any more
7193 inlined. This can be a port option in the future,
7195 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7197 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7198 hold the corresponding uninitialized symbols,
7199 * pic16_allocProcessorRegister: registers have explicit marked the
7201 * pic16_allocInternalRegister: registers are explicit marked as
7203 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7204 processing list, so bit registers were lost,
7207 * ralloc.h: added field 'accessBank' and original symbol operand
7208 in register definition,
7209 * removed the field isMapped from register definition,
7211 ** Several functions have been removed from various sources:
7212 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7213 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7214 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7215 pic16_assignRelocatableRegisters
7217 ** others have been introduced:
7218 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7219 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7221 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7223 * support/scripts/inc2h.pl: changed definition of BIT_AT
7224 to emit 'sbit at' instead of 'bit at'. This was a request.
7226 PIC16 port related preliminary changes:
7227 * gen.c: prefixed function popRegFromString with
7228 pic16_ and all references to it corrected
7229 * pcode.c: all pic16_pc_* hardware registers prefixed
7230 with underscore (_),
7231 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7232 * ralloc.c: newReg(): when register is REG_SFR then
7233 set address to rIdx,
7234 pic16_allocProcessorRegister(): marks register wasUsed=0
7235 pic16_writeUsedRegs(): added a call to assign processor
7236 registers via pic16_assignFixedRegisters
7238 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7240 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7241 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7242 variables in unused register banks. Also the SSEG is placed
7243 wherever there is enough space for it, and IDATA can be anywhere
7244 in internal RAM. For now compile using -Wl-Y[stack_size].
7245 The mem file is different for this option as well, since it
7246 makes no sense of talking about DSEG lenght.
7248 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7250 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7251 in certain cases, e.g. when ROM assignment, patch provided
7252 from Albert den Haan.

7493 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7495 * src/SDCCast.c (decorateType): disabled a transformation I added in
7496 revision 1.188 (access to fields of a structure at an absolute address);
7497 it breaks with bitfields, extern declarations, and gcse analysis.
7498 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7499 could be assigned through a pointer, so don't complain.
7500 * src/SDCCast.c (astErrors),
7502 * src/SDCCglue.c (emitRegularMap): fixed bug #847813
7504 2003-11-26 Vangelis Rokas <vrokas AT otenet.gr>

8256 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8257 fetching of the pointer
8258 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8259 copied from genNearPointerSet()
8260 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8261 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8262 If they pop r0/r1 they must be called in the opposite order than aopOp().
8263 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8264 (resp. --stack-auto), prepared for --xstack

8275 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8277 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8278 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8279 type for bits was changed. It resulted in bit variables becoming
8280 global, which is not permitted in PIC 14 assembly output.
8282 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8284 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8297 A few small changes that speed up the peephole optimizer.
8301 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8303 Try to make the peephole optimizer smarter by maintaining
8304 an association between the assembly source code and the
8305 iCodes that originated them. Put this information to use
8306 with a new peephole rule condition "notVolatile" so that
8307 the rules can be aggressive yet still safe.
8312 * src/mcs51/peeph.def
8314 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8318 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8319 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8320 if the left or right operand symbols have the accuse flag set.
8322 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8324 Changed the type of the result of the ! (NOT) operator to char;
8325 previously it returned the same type as the source. This allows
8326 us to eliminate all the genFloatNot functions (all of its target
8327 implementations were very buggy) since !float can use the same
8330 * src/SDCCicode.c (ast2iCode): ! returns char

8333 * src/z80/gen.c (genNot, genNotFloat),
8334 * src/pic/gen.c (genNot, genNotFloat),

8339 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8340 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8341 during interrupts. Ensure WSAVE is located at a shared bank address.
8342 2. Fixed page selection in some places
8343 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8344 the registers name strings.
8345 4. Fixed "signed / unsigned compare" compiler warnings.
8346 5. The PIC port manages its own allocation of the general purpose
8347 registers, but makes no attempt to reuse them. As a result when
8348 compiling it soon runs out of general purpose registers. Some
8349 additional code was added to the files pcode.c and device.c to walk
8350 through the function call tree and rename the registers so that they
8360 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8361 genPlus() & genMinus() when the result is the same as left or right
8363 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8367 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8369 Made bitfield a distinct type from bit so that bitfields
8370 convert as per ANSI C and bits retain their traditional
8371 boolean style behaviour. Implemented bitfield support in
8379 * src/ds390/gen.c: bit v bitfield split
8380 * src/z80/gen.c: New support for bitfields
8381 * support/regression/tests/bitfields.c: reenabled z80,
8384 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8386 Rules 246.x, 247.x relate to bitfields, the others speed up
8387 access to xdata mapped I/O devices.
8389 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8391 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8393 Cleaned up genPackBits and genUnpackBits and added two helper
8394 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8395 for literal assignments in genPackBits (thanks to Frieder for
8401 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8403 Fixed bug #748310 (pointer to function type mishandled when the
8404 function name is omitted). Also fixed a SIGSEGV when a function
8405 attribute (reentrant, etc) is used on a non-function or on a
8406 function but misplaced before the parameter list.
8408 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8410 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8411 * support/Util/SDCCerr.h,

8433 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8435 Made the constant following the "interrupt" keyword optional. If
8436 omitted, the function will not automatically be given an entry
8437 in the interrupt vector table (similar to #pragma NOIV, but
8438 less syntacticly kludgy). The interrupt number is also now
8439 range checked. Also fixed a bug in the high order bit example

8971 support for the PIc16 port in the ports table, when executing
8972 the compiler with no port specified on command line, a default
8973 port is selected with the new macro DEFAULT_PORT which is
8974 defined in port.h, in setDefaultOptions() linkOptions is removed
8975 from initialization assignment, since now it is a set,
8976 parseCmdLine uses setParseWithComma for linkOptions, in
8977 linkEdit() linkOptions are accessed with new function indexSet()
8978 which returns the i'th item of a set variable. See SDCCset.c, in
8979 linkEdit() when calling buildCmdLine(), added linkOptions as
8980 last argument. Now users can pass arguments to gplink via the

8995 gpasm complaining and test the linkage with gplink, _linkCmd and
8996 _asmCmd changed to be more gplink and gpasm friendly
8997 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8998 produced an error when parsed, peep rule 12 is added to utilize
8999 movff, but it is commented out since the pCode does not support
9000 yet a command with 2 address arguments
9002 2003-05-18 <johan AT balder>

10026 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
10027 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
10028 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings

10037 2003-01-06 <johan AT balder>
10039 * src/SDCCicode.c: fixed array add
10041 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
10042 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
10043 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
10045 2003-01-04 <johan AT balder>

10049 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10050 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
10052 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10053 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

10056 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10057 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
10059 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10060 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10062 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10063 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10065 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10067 * in \sdcc\as\mcs51\ changed these files in order to create an
10068 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10069 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10070 following files to include the previous two files: aslink.dsp,
10071 Makefile.aslink, Makefile.bcc, and Makefile.in.
10073 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10074 .adb instead of .cdb
10076 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10078 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10079 value from option --iram-size.
10081 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10083 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10086 2002-09-18 <wiml AT hhhh.org>
10088 * SDCClrange.h: exposed setFromRange() and setToRange()
10089 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10090 packRegsForAccUse() (bug 542397)
10091 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10092 multiple times and emitting the fetch operations more than once
10093 added aopGetUsesAcc() function to allow binary operators to
10094 fetch their operands in the correct order; made genMinus() emit
10095 compact code for X = LITERAL - Y
10097 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10098 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10099 sprintf() in line 1267.
10101 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10102 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10105 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10106 Changes to aslink (All the changes are marked with 'JCF'):
10108 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10111 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10112 area BSEG. Also moves, if possible, the DATA area down into the internal
10113 ram so more space is available.
10115 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10118 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10119 not bytes. Function summary() which creates a memory usage summary
10120 file with extension .mem. Reports of overlaping stack and small stack
10121 size. If the space for the stack is less than 16 bytes aslink trows a
10124 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10125 the 8051. Option 'y' for memory summary output file.
10127 Changes to sdcc (All the changes are marked with 'JCF'):
10129 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10131 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10132 overlaying area for it (uses RegBankUsed[4]).
10134 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10135 bank zero as used by default. By default aslink locates the stack
10136 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10137 the creation of the .mem file. Delegates the allocation of data area
10138 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10139 the begining of the stack area to aslink.
10141 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10142 glue() in SDCCglue.c creates an area for it.
10144 2002-09-03 Borut Razem <borut.razem AT siol.net>
10145 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10146 sdcc/src/pic/glue.c:
10147 introduced atexit() handler for teporay files removal in case of
10148 errors, assertions, ...
10150 2002-08-29 Borut Razem <borut.razem AT siol.net>
10151 * sdcc/support/cpp2/auto-host_vc_in.h:
10152 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10153 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10154 Maybe there is a similar problem with BORLANDC? It should be checked!
10156 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10157 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10158 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10159 was not executed, and the compiler (cl) launched a warning:
10160 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10162 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10163 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10165 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10166 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10168 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10169 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10170 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10171 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10172 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10173 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10174 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10175 - added Release configuration in VS projects
10176 - review of compiler an linker options
10177 - VC .exe files are generated in bin_vc directory, not to interfere
10178 with binaries generated from other projects (cygwin, mingw, bcc ...)
10180 * sdcc/src/yacc.dsp: added
10182 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10183 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10184 and insert the version number definitions from .version
10186 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10188 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10189 added - genarate auto-host.h using auto-host_vc_in.h as template
10192 removed from CVS, generated automatically
10194 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10195 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10197 2002-08-11 Borut Razem <borut.razem AT siol.net>
10198 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10200 2002-08-10 Borut Razem <borut.razem AT siol.net>
10201 * src/SDCCmain.c (main):
10202 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10203 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10204 The consequence was that some temporary files were not removed.
10207 unification of code in functions tempfilename() and tempfile():
10208 function tempnam() is defined in Visual Studio 6.0 and .NET
10210 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10212 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10213 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10214 - removed compiler command line option /WX: Treats all warnings as errors
10215 - update a list of source files, included into the project
10217 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10218 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10219 changed project type to Generic Project so that can be correcly converted to VS.NET project
10221 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10223 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10225 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10227 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10228 added return 0 statements after assert() to make compiler happy
10230 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10231 added newline in the def file to keep MSC compiler satisfied
10233 * sdcc/src/z80/gen.c:
10234 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10235 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10236 - solved MSC error in function aopDump()
10238 * sdcc_vc.h: define PREFIX as "\\sdcc"
10240 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10241 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
10243 2002-06-22 Scott Dattalo <scott AT dattalo.com>
10244 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10245 - Rewrote the register banking algorithm.
10246 - Added pCode live-range analysis to registers (for now, only non-used and
10247 singly-used registers optimized away)
10249 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10251 * 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.

10266 2002-04-15 Michael Hope <michaelh AT vroom>
10268 * device/lib/z80/printf.c (sprintf): Added.
10270 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
10272 * src/z80/peeph.def: Added transpose redundent load rule.
10274 * src/z80/main.c: Added force callee saves for jaune.
10276 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
10278 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10280 2002-03-28 Johan Knol <johan AT balder>
10282 * src/SDCCval.c: fixed bug #532436
10284 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10286 Added "char *Processor" field to the port structure.
10289 Added -p option. Allows port dependent processor to be specified.
10292 Initialized the new field char *Processor field to NULL in all ports
10295 Compiler generated registers for interrupt context saving
10296 were not getting allocated.
10298 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10301 Fixed left shift. Will promote the left side of a left shift
10302 if a) left shifting more than size of operand or b) when assigned
10303 to something size > size of left side
10305 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10307 tons of changes. Register allocation has been
10308 rewritten. Added customization for the various PICs. Flow
10309 analysis is restructured. ...
10311 * src/pic/device.h:
10314 * src/pic/device.c:
10315 Added. device.c is a PIC port hack to accomodate variations
10318 2002-03-13 Michael Hope <michaelh AT vroom>
10320 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10322 2002-03-04 johanknol <johanknol AT manik>
10324 * /src/SDCCval.c: fixed
10326 const unsigned char arr[][2] = { { 0, 1 } };
10327 t18.c:1: error: Initializer element is not constant

10385 * src/z80/ralloc.c (packRegsForIYUse): Fixed fp bug where four byte operands were packed into IY.
10387 2002-03-01 <johan AT FRIJA>
10389 * src/SDCCglue.c (printIvalPtr): fixed bug #524211
10391 * src/SDCCast.c (decorateType): fixed bug #524209

10413 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10415 * sdcc/src/SDCCloop.c:
10416 Previous fix was not good. basic blocks that have "break" or "return" are
10417 not really partof a loop , but live ranges used in these blocks should
10418 be live thru the entire loop, so set partOfLoop but don't add them to
10421 2002-02-21 <johan AT FRIJA>
10423 * src/SDCCcse.c: fixed bug #514308
10425 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
10428 Fixed BUG #519583. If a conditional block ended in a return/break
10429 statement inside a loop, it was not being considered part of the loop.
10431 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
10433 2002-02-10 Karl Bongers <karl AT turbobit.com>
