258 Enabled VPATH feature: changed nearly all Makefiles (149 files).
259 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
261 One basic decision: e.g. src/clean.mk includes further files. In order
262 to make this work there are two solutions:
263 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
264 run configure on them. This way they can use
265 'include $(srcdir)/port-clean.mk'
266 - always include clean.mk by the Makefile at the same level. To avoid
267 that `make clean` tries to include and build Makefile.dep the
268 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
269 implemented, because now even `make uninstall` doesn't create
270 Makefile.in. clean.mk could be eliminated by pasting it in
273 * debugger/mcs51/Makefile.in: build own objects from library sources
274 (SLIB, SDCC) in current directory
276 * configure, configure.in: renamed --disable-device-lib-build in
277 --disable-device-lib; added --enable-doc, the required tools are
278 searched by configure; added result message; the toolchain for the
279 belonging ports are now only built, if the port is enabled.
281 * support/regression/*: all output is written in directory gen, because
282 the fwk and ports directories don't livet in the build tree using vpath
284 * doc/sdccman.lyx: renamed --disable-device-lib-build to
285 --disable-device-lib, added --enable-doc, added section VPATH
287 * sim/ucsim/configure.in,
288 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
289 z80 are enabled by default
291 2006-04-24 Raphael Neider <rneider AT web.de>
293 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
294 to config word, "pic14_"-prefixed some extern functions
295 (pic14_emitConfigWord): emit __config directive(s) if assignment to
296 config word has been found
297 * src/pic/device.h: added prototypes
298 * src/pic/pcode.c: added "pic14_"-prefix where needed
299 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
301 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
303 (pic14emitRegularMap): ignore config words,
304 (pic14createInterruptVect): moved generating __config directives away

315 fixes #1469504 and #1474602,
316 (pCodeRegOptimizeRegUsage): fixed typo in comment

564 and enabled nesting of critical functions though not for gbz80
565 (genCritical, genEndCritical): added functions
566 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
567 * src/z80/mappings.i: added "ei" to all mappings

573 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
574 archive with gcc 4.1 on mips and wrote the patch"
576 2006-03-16 Raphael Neider <rneider AT web.de>
578 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
579 the left operand is shorter than the result (c* = lit-c* + int),
581 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
584 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
586 * src/.version: increased version number to 2.5.5
587 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
588 linking is done manually in pic16 port's _linkEdit,
589 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
590 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
591 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
592 allocate asmop as AOP_ACC,
593 (aopForRemat): added parameter 'bool result' in function declaration,
594 (pic16_aopGet): return AOP_ACC when accessing WREG,

606 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
607 call to allocReg, not by manually allocating a new one,
608 (pic16_assignRegisters): now before going through the register
609 allocating functions mark all registers as free. This eliminates some
610 side effects resulting from peephole parser done earlier in the backbone
612 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

670 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
671 which dumps before the function entry point a data byte which represents
672 the number of the local variables used by the specified function, added
673 'xinst' for initial support for Extended Instruction Support,
674 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
675 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
676 port->fun_prefix anymore (may change later),
677 (genFunction, genEndFunction): do not store/restore local registers for
678 _main (this should take care the --main-return command line option in
680 (genOr): removed some legacy pic-port instructions,
681 * src/pic16/genarith.c (genAddLit): re-enabled old code because
682 performing operations with SFR's causes data to be written more than
683 once to each SFR. Perhaps SFRs should be handled in special cases...
684 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
686 * src/pic16/main.c (_process_pragma): stack bound checking did not take
687 into account for stack starting position,
688 (struct OPTIONS pic16_optionsTable): added command line argument
689 --extended or -y for Extended Instruction Support,
690 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
691 (deassignLRs): *** perhaps the most important change, old 'for' code
692 (commented out for reference), didn't account for some registers which
693 were left marked 'not free' after a pointer operation. The change
694 reduces register usage a lot in some cases

3044 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3046 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
3049 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3051 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
3052 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3054 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3056 * device/lib/printf_large.c: removed inline assembly for portability and
3057 readability. Use printf_fast if speed or size are more important.
3058 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3059 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3061 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3063 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3064 prevent compiler warning
3066 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3068 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3069 moved to level 0 and declared as static. Also they are explicit
3070 placed in access bank. This was necessery because some times they
3071 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3072 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3073 optimizations. Currently only compare to unsigned char is implemented,
3074 * src/pic16/gen.c: added fReturnIdx array,
3075 * (struct resolvedIfx) is moved to gen.h and made public,
3076 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3077 * (aopForSym): added an optimization to directly store in stack of
3078 the operand of a SEND iCode,
3079 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3080 but as registers instead (AOP_REG) using the fReturnIdx array,
3081 * (pic16_freeAsmop): remove the freed register from the
3082 _G.sregsAlloc field,
3083 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3084 a compare of 'WREG',
3085 * (pic16_popGetTempRegCond): changed function prototype, now
3086 function takes also a bitVector argument v which holds the current
3087 set of registers that are allocated for stack access by aopForSym,
3088 registers allocated in aopForSym for accessing stack symbols are not
3089 any more part of the functions usedRegs field,
3090 * (genCall): some times aopOp is called for a stack variable to be
3091 send, aopForSym might perform the push, if this is true make sure
3092 that genCall doesn't push the variable twice by testing _G.resDirect,
3093 * (genFunction): changed testing for unspecified interrupt number
3094 from 256 to INTNO_UNSPEC,
3095 * modified selection scheme of frame pointer generation. Previously
3096 if function did use local registers a frame pointer was generated,
3097 now a frame pointer is generated only if function has arguments
3098 (that need PLUSW2 register access), or has stack arguments, or the
3099 compiler is not instructed to omit the frame pointer,
3100 * (genEndFunction): before restoring local registers that were saved
3101 in the function preamble, also restore the registers that *might*
3102 have been allocated for stack access,
3103 * (genRet): removed some old comments,
3104 * (genCmp, the active (RN's) version): added a call to the
3105 pic16_genCmp_special function to perform the compare with a more
3106 robust and optimized way,
3107 * (genInline): a feature has been added in inline code generation,
3108 which allows a wildcard variable substitution when writing inline
3109 assembly. Code is incomplete and experimental therefore undocumented,
3110 * (genCast): changed order of aopOp for result and right to allow
3111 aopForSym to directly load the result if possible,
3112 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3113 perform an optimized compare on some selected special occasions,
3114 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3115 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3116 generate an IVT any more,
3117 * src/pic16/main.c (pic16_optionsTable): added command line option
3119 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3120 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3122 * src/pic16/NOTES: Raphael Neider added in list of active developers
3123 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3124 jumptable_end to prevent bug #,
3125 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3126 inCond and outCond fields,
3127 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3128 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3129 turn off register spilling,
3130 * (packRegsForOneUse): synced with other ports' versions although it
3131 is not used currently,
3132 * (pic16_packRegisters): added an optimization while reading
3133 structure bitfields, some registers may be saved (malloc code is
3134 decreased by 80 bytes)
3136 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3138 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3139 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3140 this can be optimized more?
3142 2005-03-10 Raphael Neider <rneider AT web.de>
3144 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3145 genNearPointerGet): (hopefully) fixed access to bitfields via
3146 pointers (p->bitN = x; and x = p->bitN; failed)
3148 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3471 pic16_framepnt_*, pic16_stack_*, pic1_frame_* pointer variables to
3472 access stack and frame pointers. They are initially assigned to
3473 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
3474 accessing SFRs. Updated all occurences of modification of stack or
3475 frame pointer in gen.c and pcode.c,
3476 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with

3781 generated for switch statements. For now you need to set the
3782 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3783 Now 4 algorithms for mcs51 jumptable generation are used:
3784 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

3818 * added libc directory. The current version of LibC contains string
3819 functions, ctype functions and macros and some functions of the
3820 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3821 be extensively tested in the future. Standard disclaimer here.

3835 * (genCmp): experimental code for new genCmp which uses PIC18's
3836 special compare&skip instructions. Initial tests fail some times
3837 with variables grater than 1 byte in size, so new code is disabled,
3838 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3840 * (genCast): began a fix to optimize the casting of a bit to another
3841 bit, now assigning a bitfield to another bitfield will fail, sorry,

3855 registers when it shouldn't,
3856 * src/pic16/ralloc.c (allocReg): add preliminary support for
3857 supporting a limited set of temporary registers,
3859 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6866 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6867 loaded with the linker search paths (-L arguments) and the libraries
6868 to be linked with the current source (-l arguments). Changes
6869 currently will affect only the pic16 port.
6870 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6871 include path the port specific paths and port specific libraries,
6872 * gplink command now contains the $3 argument,
6873 * src/pic16/device.h,
6874 * src/pic16/device.c,: structure PIC_device is made public and

6890 Documenting changes from previous commits.
6891 * configure.in (version 1.56),
6892 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6893 when generating output files to configure the pic16 library,
6894 but now I've commented it out, since gputils aren't installed in the
6895 SF compile farm, so library won't compile
6897 * device/lib/Makefile.in (version 1.56): initially I've added in
6898 target 'all' the prerequestive 'model-pic16' so it compiled the
6899 pic16 library, but now I've commented it out for the same reasons
6901 * added targets 'model-pic16' and 'objects-pic16' to compile the
6903 * added target 'port-specific-objects-pic16' to handle the
6904 generated libraries and copy them into the build/ directory
6905 * added target 'clean-intermediate-pic16' to clean intermediate
6906 files into pic16 directory
6907 * in target 'installdirs' added line to create directory pic16 in
6908 the installation path

6911 added lines to copy all header files to installation path,
6912 * in target 'installdirs' added line create directory for pic16
6913 headers in the installation path

6929 option so that it actually works. Made it specific to the z80, since
6930 the gbz80 doesn't have these kinds of I/O ports.
6932 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6934 * device/include/z180.h,

7040 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
7041 UPPER for immediate operands,
7042 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7044 * src/pic16/peeph.def: all peepholes with movff are commented out,
7045 because there is a problem in the pcode peep optimizer,
7046 * src/pic16/ralloc.c: the register allocator can now reuse local
7047 function symbols for another function. This saves register usage.
7048 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7050 Added file src/pic16/NOTES with information about program writing on
7051 the current port version.

7156 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7158 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7159 (default behaviour).
7161 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7163 A python script to validate compiler diagnostic messages. It can be
7164 used to verify that sdcc complains about bad c source code and

7198 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7200 PIC16 port related changes:
7201 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7202 added variable stackPos,
7204 * gen.c: genCall, assignResultValue: added support for
7205 pushing/retrieving function parameters to/from stack,
7206 genFunction,genEndFunction: setup stack frame for the
7208 genAddrOf: will be changed according to bug 863624
7210 * added files genutils.c and genutils.h which contain gen*
7211 debugged and optimised functions extracted from gen.c
7213 * glue.c: added variable 'externs' which holds extern symbols,
7214 pic16emitRegularMap: is modified to properly handle relocatable
7215 symbols under the new scheme,
7216 pic16createInterruptVect: is modified
7217 pic16printPublics: is modified to emit 'global' assembler directives,
7218 added pic16_printExterns to print extern symbols,
7219 pic16glue: initializes stack/frame pointer in the beginning of
7220 the assembly output. Temporary hack, will be corrected later,
7221 because gplink yet does not support stack and SDCC does not
7222 yet support a type of crt0.o object to create the final binary.
7224 * Removed many lines that contain 8051 legacy code.
7225 * The code is finally placed under a 'code' directive.
7226 * Added port specific options.
7228 * _process_pragma: simplified since now we do not need *special*
7229 include file to define SFR registers. But a separate header
7230 will be needed. This will be developed later.
7231 * _pic16_parseOptions: added, parses port specific options:
7232 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7233 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7234 --preplace-udata-with=
7236 * _pic16_setDefaultOptions: modified to initialize section names,
7237 but hack is temporarly out of order since it needs improvement.
7238 * _pic16_genAssemblerPreamble: configuration words are emitted by
7239 their address instead of their name. This part is incomplete and
7240 supports only the 18Fxx2 devices. Other devices will emit an error
7241 during assembly since they do not contain the same set of config
7243 * _pic16_genIVT: is modified,
7245 * pcode.c: added definitions for some hardware registers that are needed
7247 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7248 All PCI entries are updated. Now LFSR is supported.
7249 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7250 * added pic16_newpCodeOpLit2 to support instructions with
7251 two literal arguments
7252 * pic16_pCode2str: corrected code that emits assembler instructions
7253 with two literal operands and those that have an access bit modifier
7254 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7255 this fixes a bug which caused some labels to be lost, when an
7256 assembler directive was added, i.e. banksel,
7257 * pic16_FixRegisterBanking: improved logic that causes the insertion
7259 * InlineFunction: functions that are called once, are not any more
7260 inlined. This can be a port option in the future,
7262 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7264 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7265 hold the corresponding uninitialized symbols,
7266 * pic16_allocProcessorRegister: registers have explicit marked the
7268 * pic16_allocInternalRegister: registers are explicit marked as
7270 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7271 processing list, so bit registers were lost,
7274 * ralloc.h: added field 'accessBank' and original symbol operand
7275 in register definition,
7276 * removed the field isMapped from register definition,
7278 ** Several functions have been removed from various sources:
7279 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7280 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7281 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7282 pic16_assignRelocatableRegisters
7284 ** others have been introduced:
7285 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7286 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7288 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7290 * support/scripts/inc2h.pl: changed definition of BIT_AT
7291 to emit 'sbit at' instead of 'bit at'. This was a request.
7293 PIC16 port related preliminary changes:
7294 * gen.c: prefixed function popRegFromString with
7295 pic16_ and all references to it corrected
7296 * pcode.c: all pic16_pc_* hardware registers prefixed
7297 with underscore (_),
7298 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7299 * ralloc.c: newReg(): when register is REG_SFR then
7300 set address to rIdx,
7301 pic16_allocProcessorRegister(): marks register wasUsed=0
7302 pic16_writeUsedRegs(): added a call to assign processor
7303 registers via pic16_assignFixedRegisters
7305 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7307 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7308 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7309 variables in unused register banks. Also the SSEG is placed
7310 wherever there is enough space for it, and IDATA can be anywhere
7311 in internal RAM. For now compile using -Wl-Y[stack_size].
7312 The mem file is different for this option as well, since it
7313 makes no sense of talking about DSEG lenght.
7315 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7317 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7318 in certain cases, e.g. when ROM assignment, patch provided
7319 from Albert den Haan.
7321 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8206 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
8207 support for standard C idiom of memory mapped variables; for
8208 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8209 to xdata int at 0x1234 tempvar = 1.
8210 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8211 provided by Akiya ISHIDA

8227 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8229 Fixed bug #621531 (const & volatile confusion in the type chain).
8230 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

8322 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8323 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8324 fetching of the pointer
8325 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8326 copied from genNearPointerSet()
8327 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8328 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8329 If they pop r0/r1 they must be called in the opposite order than aopOp().
8330 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8331 (resp. --stack-auto), prepared for --xstack

8340 these ports have their own __sdcc_external_start()
8342 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8344 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8345 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8346 type for bits was changed. It resulted in bit variables becoming
8347 global, which is not permitted in PIC 14 assembly output.
8349 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8351 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8364 A few small changes that speed up the peephole optimizer.
8368 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8370 Try to make the peephole optimizer smarter by maintaining
8371 an association between the assembly source code and the
8372 iCodes that originated them. Put this information to use
8373 with a new peephole rule condition "notVolatile" so that
8374 the rules can be aggressive yet still safe.
8379 * src/mcs51/peeph.def
8381 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8385 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8386 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8387 if the left or right operand symbols have the accuse flag set.
8389 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8391 Changed the type of the result of the ! (NOT) operator to char;
8392 previously it returned the same type as the source. This allows
8393 us to eliminate all the genFloatNot functions (all of its target
8394 implementations were very buggy) since !float can use the same
8397 * src/SDCCicode.c (ast2iCode): ! returns char

8404 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
8406 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8407 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8408 during interrupts. Ensure WSAVE is located at a shared bank address.
8409 2. Fixed page selection in some places
8410 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8411 the registers name strings.
8412 4. Fixed "signed / unsigned compare" compiler warnings.
8413 5. The PIC port manages its own allocation of the general purpose
8414 registers, but makes no attempt to reuse them. As a result when
8415 compiling it soon runs out of general purpose registers. Some
8416 additional code was added to the files pcode.c and device.c to walk
8417 through the function call tree and rename the registers so that they
8427 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8428 genPlus() & genMinus() when the result is the same as left or right

8434 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8436 Made bitfield a distinct type from bit so that bitfields
8437 convert as per ANSI C and bits retain their traditional
8438 boolean style behaviour. Implemented bitfield support in
8446 * src/ds390/gen.c: bit v bitfield split
8447 * src/z80/gen.c: New support for bitfields
8448 * support/regression/tests/bitfields.c: reenabled z80,
8451 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8453 Rules 246.x, 247.x relate to bitfields, the others speed up
8454 access to xdata mapped I/O devices.
8456 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8458 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8460 Cleaned up genPackBits and genUnpackBits and added two helper
8461 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8462 for literal assignments in genPackBits (thanks to Frieder for
8468 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8470 Fixed bug #748310 (pointer to function type mishandled when the
8471 function name is omitted). Also fixed a SIGSEGV when a function
8472 attribute (reentrant, etc) is used on a non-function or on a
8473 function but misplaced before the parameter list.
8475 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8477 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8478 * support/Util/SDCCerr.h,
8479 * support/Util/SDCCerr.c: Added func attr misuse error msg

8500 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8502 Made the constant following the "interrupt" keyword optional. If
8503 omitted, the function will not automatically be given an entry
8504 in the interrupt vector table (similar to #pragma NOIV, but
8505 less syntacticly kludgy). The interrupt number is also now
8506 range checked. Also fixed a bug in the high order bit example

8520 * src/SDCCicode.c (operandOperation): rewritten some ops
8521 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8522 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8524 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8525 be re-activated by defining REDUCE_LITERALS)
8526 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8527 unsigned, but are signed by default
8528 * src/SDCCval.c (constVal): rearranged
8529 * src/SDCCval.c (valMod): preliminary fix
8530 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9036 added if/endif conditional macros to remove options help
9037 messages from optionsTable when a port is not configured, added
9038 support for the PIc16 port in the ports table, when executing
9039 the compiler with no port specified on command line, a default
9040 port is selected with the new macro DEFAULT_PORT which is
9041 defined in port.h, in setDefaultOptions() linkOptions is removed
9042 from initialization assignment, since now it is a set,
9043 parseCmdLine uses setParseWithComma for linkOptions, in
9044 linkEdit() linkOptions are accessed with new function indexSet()
9045 which returns the i'th item of a set variable. See SDCCset.c, in
9046 linkEdit() when calling buildCmdLine(), added linkOptions as
9047 last argument. Now users can pass arguments to gplink via the
9048 -Wl option, main() uses pic16glue() to glue up pic16 programs

9061 * src/pic16/main.c: __config directives are commented out to stop
9062 gpasm complaining and test the linkage with gplink, _linkCmd and
9063 _asmCmd changed to be more gplink and gpasm friendly
9064 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9065 produced an error when parsed, peep rule 12 is added to utilize
9066 movff, but it is commented out since the pCode does not support
9067 yet a command with 2 address arguments
9069 2003-05-18 <johan AT balder>
9071 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

10129 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10130 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10132 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10134 * in \sdcc\as\mcs51\ changed these files in order to create an
10135 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10136 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10137 following files to include the previous two files: aslink.dsp,
10138 Makefile.aslink, Makefile.bcc, and Makefile.in.
10140 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10141 .adb instead of .cdb
10143 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10145 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10146 value from option --iram-size.
10148 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10150 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10153 2002-09-18 <wiml AT hhhh.org>
10155 * SDCClrange.h: exposed setFromRange() and setToRange()
10156 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10157 packRegsForAccUse() (bug 542397)
10158 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10159 multiple times and emitting the fetch operations more than once
10160 added aopGetUsesAcc() function to allow binary operators to
10161 fetch their operands in the correct order; made genMinus() emit
10162 compact code for X = LITERAL - Y
10164 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10165 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10166 sprintf() in line 1267.
10168 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10169 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10172 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10173 Changes to aslink (All the changes are marked with 'JCF'):
10175 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10178 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10179 area BSEG. Also moves, if possible, the DATA area down into the internal
10180 ram so more space is available.
10182 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10185 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10186 not bytes. Function summary() which creates a memory usage summary
10187 file with extension .mem. Reports of overlaping stack and small stack
10188 size. If the space for the stack is less than 16 bytes aslink trows a
10191 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10192 the 8051. Option 'y' for memory summary output file.
10194 Changes to sdcc (All the changes are marked with 'JCF'):
10196 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10198 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10199 overlaying area for it (uses RegBankUsed[4]).
10201 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10202 bank zero as used by default. By default aslink locates the stack
10203 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10204 the creation of the .mem file. Delegates the allocation of data area
10205 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10206 the begining of the stack area to aslink.
10208 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10209 glue() in SDCCglue.c creates an area for it.
10211 2002-09-03 Borut Razem <borut.razem AT siol.net>
10212 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10213 sdcc/src/pic/glue.c:
10214 introduced atexit() handler for teporay files removal in case of
10215 errors, assertions, ...
10217 2002-08-29 Borut Razem <borut.razem AT siol.net>
10218 * sdcc/support/cpp2/auto-host_vc_in.h:
10219 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10220 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10221 Maybe there is a similar problem with BORLANDC? It should be checked!
10223 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10224 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10225 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10226 was not executed, and the compiler (cl) launched a warning:
10227 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10229 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10230 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10232 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10233 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10235 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10236 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10237 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10238 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10239 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10240 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10241 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10242 - added Release configuration in VS projects
10243 - review of compiler an linker options
10244 - VC .exe files are generated in bin_vc directory, not to interfere
10245 with binaries generated from other projects (cygwin, mingw, bcc ...)
10247 * sdcc/src/yacc.dsp: added
10249 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10250 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10251 and insert the version number definitions from .version
10253 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10255 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10256 added - genarate auto-host.h using auto-host_vc_in.h as template
10259 removed from CVS, generated automatically
10261 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10262 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10264 2002-08-11 Borut Razem <borut.razem AT siol.net>
10265 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10267 2002-08-10 Borut Razem <borut.razem AT siol.net>
10268 * src/SDCCmain.c (main):
10269 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10270 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10271 The consequence was that some temporary files were not removed.
10274 unification of code in functions tempfilename() and tempfile():
10275 function tempnam() is defined in Visual Studio 6.0 and .NET
10277 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10279 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10280 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10281 - removed compiler command line option /WX: Treats all warnings as errors
10282 - update a list of source files, included into the project
10284 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10285 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10286 changed project type to Generic Project so that can be correcly converted to VS.NET project
10288 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10290 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10292 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10294 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10295 added return 0 statements after assert() to make compiler happy
10297 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10298 added newline in the def file to keep MSC compiler satisfied
10300 * sdcc/src/z80/gen.c:
10301 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10302 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10303 - solved MSC error in function aopDump()
10305 * sdcc_vc.h: define PREFIX as "\\sdcc"
10307 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10308 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10311 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10312 - Rewrote the register banking algorithm.
10313 - Added pCode live-range analysis to registers (for now, only non-used and
10314 singly-used registers optimized away)
10316 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10318 * 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.

10343 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
10345 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10347 2002-03-28 Johan Knol <johan AT balder>
10349 * src/SDCCval.c: fixed bug #532436
10351 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10353 Added "char *Processor" field to the port structure.
10356 Added -p option. Allows port dependent processor to be specified.
10359 Initialized the new field char *Processor field to NULL in all ports
10362 Compiler generated registers for interrupt context saving
10363 were not getting allocated.
10365 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10368 Fixed left shift. Will promote the left side of a left shift
10369 if a) left shifting more than size of operand or b) when assigned
10370 to something size > size of left side
10372 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10374 tons of changes. Register allocation has been
10375 rewritten. Added customization for the various PICs. Flow
10376 analysis is restructured. ...
10378 * src/pic/device.h:
10381 * src/pic/device.c:
10382 Added. device.c is a PIC port hack to accomodate variations
10385 2002-03-13 Michael Hope <michaelh AT vroom>
10387 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10389 2002-03-04 johanknol <johanknol AT manik>
10391 * /src/SDCCval.c: fixed
10393 const unsigned char arr[][2] = { { 0, 1 } };
10394 t18.c:1: error: Initializer element is not constant
10396 2002-03-04 bela <bela AT manik>
