184 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
186 Enabled VPATH feature: changed nearly all Makefiles (149 files).
187 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
189 One basic decision: e.g. src/clean.mk includes further files. In order
190 to make this work there are two solutions:
191 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
192 run configure on them. This way they can use
193 'include $(srcdir)/port-clean.mk'
194 - always include clean.mk by the Makefile at the same level. To avoid
195 that `make clean` tries to include and build Makefile.dep the
196 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
197 implemented, because now even `make uninstall` doesn't create
198 Makefile.in. clean.mk could be eliminated by pasting it in
201 * debugger/mcs51/Makefile.in: build own objects from library sources
202 (SLIB, SDCC) in current directory
204 * configure, configure.in: renamed --disable-device-lib-build in
205 --disable-device-lib; added --enable-doc, the required tools are
206 searched by configure; added result message; the toolchain for the
207 belonging ports are now only built, if the port is enabled.
209 * support/regression/*: all output is written in directory gen, because
210 the fwk and ports directories don't livet in the build tree using vpath
212 * doc/sdccman.lyx: renamed --disable-device-lib-build to
213 --disable-device-lib, added --enable-doc, added section VPATH
215 * sim/ucsim/configure.in,
216 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
217 z80 are enabled by default
219 2006-04-24 Raphael Neider <rneider AT web.de>
221 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
222 to config word, "pic14_"-prefixed some extern functions
223 (pic14_emitConfigWord): emit __config directive(s) if assignment to
224 config word has been found
225 * src/pic/device.h: added prototypes
226 * src/pic/pcode.c: added "pic14_"-prefix where needed

229 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

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

500 submitted by the Debian SDCC maintainer Aurelien Jarno:
501 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
502 archive with gcc 4.1 on mips and wrote the patch"
504 2006-03-16 Raphael Neider <rneider AT web.de>
506 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
507 the left operand is shorter than the result (c* = lit-c* + int),
509 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
512 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
514 * src/.version: increased version number to 2.5.5
515 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
516 linking is done manually in pic16 port's _linkEdit,
517 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
518 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
519 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
520 allocate asmop as AOP_ACC,
521 (aopForRemat): added parameter 'bool result' in function declaration,
522 (pic16_aopGet): return AOP_ACC when accessing WREG,

527 calling function in absolute addresses,
528 (genAssign): take into account AOP_ACC asmop,

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

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

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

2980 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2982 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2984 * device/lib/printf_large.c: removed inline assembly for portability and
2985 readability. Use printf_fast if speed or size are more important.
2986 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2987 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2989 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2991 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2992 prevent compiler warning
2994 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2996 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2997 moved to level 0 and declared as static. Also they are explicit
2998 placed in access bank. This was necessery because some times they
2999 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3000 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3001 optimizations. Currently only compare to unsigned char is implemented,
3002 * src/pic16/gen.c: added fReturnIdx array,
3003 * (struct resolvedIfx) is moved to gen.h and made public,
3004 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3005 * (aopForSym): added an optimization to directly store in stack of
3006 the operand of a SEND iCode,
3007 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3008 but as registers instead (AOP_REG) using the fReturnIdx array,
3009 * (pic16_freeAsmop): remove the freed register from the
3010 _G.sregsAlloc field,
3011 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3012 a compare of 'WREG',
3013 * (pic16_popGetTempRegCond): changed function prototype, now
3014 function takes also a bitVector argument v which holds the current
3015 set of registers that are allocated for stack access by aopForSym,
3016 registers allocated in aopForSym for accessing stack symbols are not
3017 any more part of the functions usedRegs field,
3018 * (genCall): some times aopOp is called for a stack variable to be
3019 send, aopForSym might perform the push, if this is true make sure
3020 that genCall doesn't push the variable twice by testing _G.resDirect,
3021 * (genFunction): changed testing for unspecified interrupt number
3022 from 256 to INTNO_UNSPEC,
3023 * modified selection scheme of frame pointer generation. Previously
3024 if function did use local registers a frame pointer was generated,
3025 now a frame pointer is generated only if function has arguments
3026 (that need PLUSW2 register access), or has stack arguments, or the
3027 compiler is not instructed to omit the frame pointer,
3028 * (genEndFunction): before restoring local registers that were saved
3029 in the function preamble, also restore the registers that *might*
3030 have been allocated for stack access,
3031 * (genRet): removed some old comments,
3032 * (genCmp, the active (RN's) version): added a call to the
3033 pic16_genCmp_special function to perform the compare with a more
3034 robust and optimized way,
3035 * (genInline): a feature has been added in inline code generation,
3036 which allows a wildcard variable substitution when writing inline
3037 assembly. Code is incomplete and experimental therefore undocumented,
3038 * (genCast): changed order of aopOp for result and right to allow

3709 generated for switch statements. For now you need to set the
3710 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3711 Now 4 algorithms for mcs51 jumptable generation are used:
3712 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

3746 * added libc directory. The current version of LibC contains string
3747 functions, ctype functions and macros and some functions of the
3748 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3749 be extensively tested in the future. Standard disclaimer here.

3762 * (pic16_storeForReturn): optimized return of 0,
3763 * (genCmp): experimental code for new genCmp which uses PIC18's
3764 special compare&skip instructions. Initial tests fail some times
3765 with variables grater than 1 byte in size, so new code is disabled,
3766 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3768 * (genCast): began a fix to optimize the casting of a bit to another
3769 bit, now assigning a bitfield to another bitfield will fail, sorry,

3783 registers when it shouldn't,
3784 * src/pic16/ralloc.c (allocReg): add preliminary support for
3785 supporting a limited set of temporary registers,
3787 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6795 loaded with the linker search paths (-L arguments) and the libraries
6796 to be linked with the current source (-l arguments). Changes
6797 currently will affect only the pic16 port.
6798 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6799 include path the port specific paths and port specific libraries,
6800 * gplink command now contains the $3 argument,
6801 * src/pic16/device.h,
6802 * src/pic16/device.c,: structure PIC_device is made public and

6818 Documenting changes from previous commits.
6819 * configure.in (version 1.56),
6820 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6821 when generating output files to configure the pic16 library,
6822 but now I've commented it out, since gputils aren't installed in the
6823 SF compile farm, so library won't compile
6825 * device/lib/Makefile.in (version 1.56): initially I've added in
6826 target 'all' the prerequestive 'model-pic16' so it compiled the
6827 pic16 library, but now I've commented it out for the same reasons
6829 * added targets 'model-pic16' and 'objects-pic16' to compile the
6831 * added target 'port-specific-objects-pic16' to handle the
6832 generated libraries and copy them into the build/ directory
6833 * added target 'clean-intermediate-pic16' to clean intermediate
6834 files into pic16 directory
6835 * in target 'installdirs' added line to create directory pic16 in

7080 * src/SDCCast.c (decorateType),
7081 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
7082 LEFT_OP (left shift)
7084 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7086 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7087 (default behaviour).
7089 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7091 A python script to validate compiler diagnostic messages. It can be
7092 used to verify that sdcc complains about bad c source code and
7093 gives a good location of the error.
7094 * support/valdiag/Makefile,
7095 * support/valdiag/valdiag.py,
7096 * support/valdiag/tests/*
7098 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7109 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7111 * src/common.h: added ifndef/define/endif macros
7112 around the header file.
7113 Bug reported from Jesus Calvino-Fraga
7115 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7117 * sdcc.spec: updated
7118 * device/include/Makefile.in: don't install CVS directories
7119 * device/lib/Makefile.in: added removal of CVS directories after install
7120 * doc/Makefile: fixed install, added local_icons
7121 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7122 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7123 * src/ds390/gen.c (genRightShift): fixed bug #870788

7126 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7128 PIC16 port related changes:
7129 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7130 added variable stackPos,
7132 * gen.c: genCall, assignResultValue: added support for
7133 pushing/retrieving function parameters to/from stack,
7134 genFunction,genEndFunction: setup stack frame for the
7136 genAddrOf: will be changed according to bug 863624
7138 * added files genutils.c and genutils.h which contain gen*
7139 debugged and optimised functions extracted from gen.c
7141 * glue.c: added variable 'externs' which holds extern symbols,
7142 pic16emitRegularMap: is modified to properly handle relocatable
7143 symbols under the new scheme,
7144 pic16createInterruptVect: is modified
7145 pic16printPublics: is modified to emit 'global' assembler directives,
7146 added pic16_printExterns to print extern symbols,
7147 pic16glue: initializes stack/frame pointer in the beginning of
7148 the assembly output. Temporary hack, will be corrected later,
7149 because gplink yet does not support stack and SDCC does not
7150 yet support a type of crt0.o object to create the final binary.
7152 * Removed many lines that contain 8051 legacy code.
7153 * The code is finally placed under a 'code' directive.
7154 * Added port specific options.
7156 * _process_pragma: simplified since now we do not need *special*
7157 include file to define SFR registers. But a separate header
7158 will be needed. This will be developed later.
7159 * _pic16_parseOptions: added, parses port specific options:
7160 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7161 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7162 --preplace-udata-with=
7164 * _pic16_setDefaultOptions: modified to initialize section names,
7165 but hack is temporarly out of order since it needs improvement.
7166 * _pic16_genAssemblerPreamble: configuration words are emitted by
7167 their address instead of their name. This part is incomplete and
7168 supports only the 18Fxx2 devices. Other devices will emit an error
7169 during assembly since they do not contain the same set of config
7171 * _pic16_genIVT: is modified,
7173 * pcode.c: added definitions for some hardware registers that are needed
7175 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7176 All PCI entries are updated. Now LFSR is supported.
7177 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7178 * added pic16_newpCodeOpLit2 to support instructions with
7179 two literal arguments
7180 * pic16_pCode2str: corrected code that emits assembler instructions
7181 with two literal operands and those that have an access bit modifier
7182 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7183 this fixes a bug which caused some labels to be lost, when an
7184 assembler directive was added, i.e. banksel,
7185 * pic16_FixRegisterBanking: improved logic that causes the insertion
7187 * InlineFunction: functions that are called once, are not any more
7188 inlined. This can be a port option in the future,
7190 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7192 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7193 hold the corresponding uninitialized symbols,
7194 * pic16_allocProcessorRegister: registers have explicit marked the
7196 * pic16_allocInternalRegister: registers are explicit marked as
7198 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7199 processing list, so bit registers were lost,
7202 * ralloc.h: added field 'accessBank' and original symbol operand
7203 in register definition,
7204 * removed the field isMapped from register definition,
7206 ** Several functions have been removed from various sources:
7207 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7208 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7209 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7210 pic16_assignRelocatableRegisters
7212 ** others have been introduced:
7213 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7214 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7216 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7218 * support/scripts/inc2h.pl: changed definition of BIT_AT
7219 to emit 'sbit at' instead of 'bit at'. This was a request.
7221 PIC16 port related preliminary changes:
7222 * gen.c: prefixed function popRegFromString with
7223 pic16_ and all references to it corrected
7224 * pcode.c: all pic16_pc_* hardware registers prefixed
7225 with underscore (_),
7226 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7227 * ralloc.c: newReg(): when register is REG_SFR then
7228 set address to rIdx,
7229 pic16_allocProcessorRegister(): marks register wasUsed=0
7230 pic16_writeUsedRegs(): added a call to assign processor
7231 registers via pic16_assignFixedRegisters
7233 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7235 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7236 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7237 variables in unused register banks. Also the SSEG is placed
7238 wherever there is enough space for it, and IDATA can be anywhere
7239 in internal RAM. For now compile using -Wl-Y[stack_size].
7240 The mem file is different for this option as well, since it
7241 makes no sense of talking about DSEG lenght.
7243 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7245 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7246 in certain cases, e.g. when ROM assignment, patch provided
7247 from Albert den Haan.

7488 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7490 * src/SDCCast.c (decorateType): disabled a transformation I added in
7491 revision 1.188 (access to fields of a structure at an absolute address);
7492 it breaks with bitfields, extern declarations, and gcse analysis.
7493 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7494 could be assigned through a pointer, so don't complain.
7495 * src/SDCCast.c (astErrors),
7497 * src/SDCCglue.c (emitRegularMap): fixed bug #847813
7499 2003-11-26 Vangelis Rokas <vrokas AT otenet.gr>

8134 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
8135 support for standard C idiom of memory mapped variables; for
8136 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8137 to xdata int at 0x1234 tempvar = 1.

8250 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8251 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8252 fetching of the pointer
8253 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8254 copied from genNearPointerSet()
8255 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8256 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8257 If they pop r0/r1 they must be called in the opposite order than aopOp().
8258 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8259 (resp. --stack-auto), prepared for --xstack

8270 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8272 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8273 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8274 type for bits was changed. It resulted in bit variables becoming
8275 global, which is not permitted in PIC 14 assembly output.
8277 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8279 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8292 A few small changes that speed up the peephole optimizer.
8296 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8298 Try to make the peephole optimizer smarter by maintaining
8299 an association between the assembly source code and the
8300 iCodes that originated them. Put this information to use
8301 with a new peephole rule condition "notVolatile" so that
8302 the rules can be aggressive yet still safe.
8307 * src/mcs51/peeph.def
8309 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8313 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8314 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8315 if the left or right operand symbols have the accuse flag set.
8317 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8319 Changed the type of the result of the ! (NOT) operator to char;
8320 previously it returned the same type as the source. This allows
8321 us to eliminate all the genFloatNot functions (all of its target
8322 implementations were very buggy) since !float can use the same
8325 * src/SDCCicode.c (ast2iCode): ! returns char

8334 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8335 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8336 during interrupts. Ensure WSAVE is located at a shared bank address.
8337 2. Fixed page selection in some places
8338 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8339 the registers name strings.
8340 4. Fixed "signed / unsigned compare" compiler warnings.
8341 5. The PIC port manages its own allocation of the general purpose
8342 registers, but makes no attempt to reuse them. As a result when
8343 compiling it soon runs out of general purpose registers. Some
8344 additional code was added to the files pcode.c and device.c to walk
8345 through the function call tree and rename the registers so that they
8355 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8356 genPlus() & genMinus() when the result is the same as left or right

8362 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8364 Made bitfield a distinct type from bit so that bitfields
8365 convert as per ANSI C and bits retain their traditional
8366 boolean style behaviour. Implemented bitfield support in
8374 * src/ds390/gen.c: bit v bitfield split
8375 * src/z80/gen.c: New support for bitfields
8376 * support/regression/tests/bitfields.c: reenabled z80,
8379 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8381 Rules 246.x, 247.x relate to bitfields, the others speed up
8382 access to xdata mapped I/O devices.
8384 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8386 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8388 Cleaned up genPackBits and genUnpackBits and added two helper
8389 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8390 for literal assignments in genPackBits (thanks to Frieder for
8396 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8398 Fixed bug #748310 (pointer to function type mishandled when the
8399 function name is omitted). Also fixed a SIGSEGV when a function
8400 attribute (reentrant, etc) is used on a non-function or on a
8401 function but misplaced before the parameter list.
8403 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8405 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8406 * support/Util/SDCCerr.h,

8428 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8430 Made the constant following the "interrupt" keyword optional. If
8431 omitted, the function will not automatically be given an entry
8432 in the interrupt vector table (similar to #pragma NOIV, but
8433 less syntacticly kludgy). The interrupt number is also now
8434 range checked. Also fixed a bug in the high order bit example

8450 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8452 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8453 be re-activated by defining REDUCE_LITERALS)

8500 constants are unsigned; added recognition of "u" flag for unsigned
8501 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8502 * src/SDCCval.c (valDiv, valMod): fixed signdness
8503 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8504 signedness of modulo, left and right shift

8965 messages from optionsTable when a port is not configured, added
8966 support for the PIc16 port in the ports table, when executing
8967 the compiler with no port specified on command line, a default
8968 port is selected with the new macro DEFAULT_PORT which is
8969 defined in port.h, in setDefaultOptions() linkOptions is removed
8970 from initialization assignment, since now it is a set,
8971 parseCmdLine uses setParseWithComma for linkOptions, in
8972 linkEdit() linkOptions are accessed with new function indexSet()
8973 which returns the i'th item of a set variable. See SDCCset.c, in
8974 linkEdit() when calling buildCmdLine(), added linkOptions as
8975 last argument. Now users can pass arguments to gplink via the
8976 -Wl option, main() uses pic16glue() to glue up pic16 programs

8990 gpasm complaining and test the linkage with gplink, _linkCmd and
8991 _asmCmd changed to be more gplink and gpasm friendly
8992 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8993 produced an error when parsed, peep rule 12 is added to utilize
8994 movff, but it is commented out since the pCode does not support
8995 yet a command with 2 address arguments
8997 2003-05-18 <johan AT balder>
8999 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

10044 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10045 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
10047 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10048 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

10057 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10058 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10060 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10062 * in \sdcc\as\mcs51\ changed these files in order to create an
10063 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10064 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10065 following files to include the previous two files: aslink.dsp,
10066 Makefile.aslink, Makefile.bcc, and Makefile.in.
10068 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10069 .adb instead of .cdb
10071 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10073 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10074 value from option --iram-size.
10076 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10078 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10081 2002-09-18 <wiml AT hhhh.org>
10083 * SDCClrange.h: exposed setFromRange() and setToRange()
10084 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10085 packRegsForAccUse() (bug 542397)
10086 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10087 multiple times and emitting the fetch operations more than once
10088 added aopGetUsesAcc() function to allow binary operators to
10089 fetch their operands in the correct order; made genMinus() emit
10090 compact code for X = LITERAL - Y
10092 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10093 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10094 sprintf() in line 1267.
10096 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10097 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10100 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10101 Changes to aslink (All the changes are marked with 'JCF'):
10103 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10106 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10107 area BSEG. Also moves, if possible, the DATA area down into the internal
10108 ram so more space is available.
10110 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10113 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10114 not bytes. Function summary() which creates a memory usage summary
10115 file with extension .mem. Reports of overlaping stack and small stack
10116 size. If the space for the stack is less than 16 bytes aslink trows a
10119 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10120 the 8051. Option 'y' for memory summary output file.
10122 Changes to sdcc (All the changes are marked with 'JCF'):
10124 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10126 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10127 overlaying area for it (uses RegBankUsed[4]).
10129 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10130 bank zero as used by default. By default aslink locates the stack
10131 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10132 the creation of the .mem file. Delegates the allocation of data area
10133 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10134 the begining of the stack area to aslink.
10136 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10137 glue() in SDCCglue.c creates an area for it.
10139 2002-09-03 Borut Razem <borut.razem AT siol.net>
10140 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10141 sdcc/src/pic/glue.c:
10142 introduced atexit() handler for teporay files removal in case of
10143 errors, assertions, ...
10145 2002-08-29 Borut Razem <borut.razem AT siol.net>
10146 * sdcc/support/cpp2/auto-host_vc_in.h:
10147 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10148 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10149 Maybe there is a similar problem with BORLANDC? It should be checked!
10151 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10152 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10153 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10154 was not executed, and the compiler (cl) launched a warning:
10155 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10157 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10158 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10160 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10161 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10163 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10164 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10165 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10166 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10167 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10168 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10169 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10170 - added Release configuration in VS projects
10171 - review of compiler an linker options
10172 - VC .exe files are generated in bin_vc directory, not to interfere
10173 with binaries generated from other projects (cygwin, mingw, bcc ...)
10175 * sdcc/src/yacc.dsp: added
10177 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10178 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10179 and insert the version number definitions from .version
10181 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10183 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10184 added - genarate auto-host.h using auto-host_vc_in.h as template
10187 removed from CVS, generated automatically
10189 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10190 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10192 2002-08-11 Borut Razem <borut.razem AT siol.net>
10193 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10195 2002-08-10 Borut Razem <borut.razem AT siol.net>
10196 * src/SDCCmain.c (main):
10197 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10198 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10199 The consequence was that some temporary files were not removed.
10202 unification of code in functions tempfilename() and tempfile():
10203 function tempnam() is defined in Visual Studio 6.0 and .NET
10205 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10207 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10208 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10209 - removed compiler command line option /WX: Treats all warnings as errors
10210 - update a list of source files, included into the project
10212 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10213 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10214 changed project type to Generic Project so that can be correcly converted to VS.NET project
10216 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10218 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10220 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10222 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10223 added return 0 statements after assert() to make compiler happy
10225 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10226 added newline in the def file to keep MSC compiler satisfied
10228 * sdcc/src/z80/gen.c:
10229 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10230 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10231 - solved MSC error in function aopDump()
10233 * sdcc_vc.h: define PREFIX as "\\sdcc"
10235 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10236 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
10238 2002-06-22 Scott Dattalo <scott AT dattalo.com>
10239 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10240 - Rewrote the register banking algorithm.
10241 - Added pCode live-range analysis to registers (for now, only non-used and
10242 singly-used registers optimized away)
10244 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10246 * 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.

10263 * device/lib/z80/printf.c (sprintf): Added.
10265 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
10267 * src/z80/peeph.def: Added transpose redundent load rule.
10269 * src/z80/main.c: Added force callee saves for jaune.
10271 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
10273 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10275 2002-03-28 Johan Knol <johan AT balder>
10277 * src/SDCCval.c: fixed bug #532436
10279 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10281 Added "char *Processor" field to the port structure.
10284 Added -p option. Allows port dependent processor to be specified.
10287 Initialized the new field char *Processor field to NULL in all ports
10290 Compiler generated registers for interrupt context saving
10291 were not getting allocated.
10293 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10296 Fixed left shift. Will promote the left side of a left shift
10297 if a) left shifting more than size of operand or b) when assigned
10298 to something size > size of left side
10300 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10302 tons of changes. Register allocation has been
10303 rewritten. Added customization for the various PICs. Flow
10304 analysis is restructured. ...
10306 * src/pic/device.h:
10309 * src/pic/device.c:
10310 Added. device.c is a PIC port hack to accomodate variations
10313 2002-03-13 Michael Hope <michaelh AT vroom>
10315 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10317 2002-03-04 johanknol <johanknol AT manik>
10319 * /src/SDCCval.c: fixed
10321 const unsigned char arr[][2] = { { 0, 1 } };

10408 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10410 * sdcc/src/SDCCloop.c:
10411 Previous fix was not good. basic blocks that have "break" or "return" are
10412 not really partof a loop , but live ranges used in these blocks should
10413 be live thru the entire loop, so set partOfLoop but don't add them to
10416 2002-02-21 <johan AT FRIJA>
10418 * src/SDCCcse.c: fixed bug #514308
10420 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

10424 statement inside a loop, it was not being considered part of the loop.
10426 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
10428 2002-02-10 Karl Bongers <karl AT turbobit.com>
