1 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
6 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
9 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
11 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
13 * device/lib/printf_large.c: removed inline assembly for portability and
14 readability. Use printf_fast if speed or size are more important.
15 * src/pic16/gen.c: removed conditions around use of DEBUGpc
16 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
18 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
20 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
21 prevent compiler warning
23 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
25 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
26 moved to level 0 and declared as static. Also they are explicit
27 placed in access bank. This was necessery because some times they
28 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
29 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
30 optimizations. Currently only compare to unsigned char is implemented,
31 * src/pic16/gen.c: added fReturnIdx array,
32 * (struct resolvedIfx) is moved to gen.h and made public,
33 * (struct _G): added sregsAlloc and sregsAllocSet fields,
34 * (aopForSym): added an optimization to directly store in stack of
35 the operand of a SEND iCode,
36 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
37 but as registers instead (AOP_REG) using the fReturnIdx array,
38 * (pic16_freeAsmop): remove the freed register from the
40 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
42 * (pic16_popGetTempRegCond): changed function prototype, now
43 function takes also a bitVector argument v which holds the current
44 set of registers that are allocated for stack access by aopForSym,
45 registers allocated in aopForSym for accessing stack symbols are not
46 any more part of the functions usedRegs field,
47 * (genCall): some times aopOp is called for a stack variable to be
48 send, aopForSym might perform the push, if this is true make sure
49 that genCall doesn't push the variable twice by testing _G.resDirect,
50 * (genFunction): changed testing for unspecified interrupt number
51 from 256 to INTNO_UNSPEC,
52 * modified selection scheme of frame pointer generation. Previously
53 if function did use local registers a frame pointer was generated,
54 now a frame pointer is generated only if function has arguments
55 (that need PLUSW2 register access), or has stack arguments, or the
56 compiler is not instructed to omit the frame pointer,
57 * (genEndFunction): before restoring local registers that were saved
58 in the function preamble, also restore the registers that *might*
59 have been allocated for stack access,
60 * (genRet): removed some old comments,
61 * (genCmp, the active (RN's) version): added a call to the
62 pic16_genCmp_special function to perform the compare with a more
63 robust and optimized way,
64 * (genInline): a feature has been added in inline code generation,
65 which allows a wildcard variable substitution when writing inline
66 assembly. Code is incomplete and experimental therefore undocumented,
67 * (genCast): changed order of aopOp for result and right to allow
68 aopForSym to directly load the result if possible,
69 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
70 perform an optimized compare on some selected special occasions,
71 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
72 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
73 generate an IVT any more,
74 * src/pic16/main.c (pic16_optionsTable): added command line option
76 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
77 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
79 * src/pic16/NOTES: Raphael Neider added in list of active developers
80 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
81 jumptable_end to prevent bug #,
82 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
83 inCond and outCond fields,
84 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
85 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
86 turn off register spilling,
87 * (packRegsForOneUse): synced with other ports' versions although it
88 is not used currently,
89 * (pic16_packRegisters): added an optimization while reading
90 structure bitfields, some registers may be saved (malloc code is
91 decreased by 80 bytes)
93 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
95 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
96 left is a bitfield, if yes, then don't optimize assignment. Perhaps
97 this can be optimized more?
99 2005-03-10 Raphael Neider <rneider AT web.de>
101 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
102 genNearPointerGet): (hopefully) fixed access to bitfields via
103 pointers (p->bitN = x; and x = p->bitN; failed)
105 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
107 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

795 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
797 * (genCast): began a fix to optimize the casting of a bit to another

3824 loaded with the linker search paths (-L arguments) and the libraries
3825 to be linked with the current source (-l arguments). Changes
3826 currently will affect only the pic16 port.
3827 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3828 include path the port specific paths and port specific libraries,
3829 * gplink command now contains the $3 argument,
3830 * src/pic16/device.h,
3831 * src/pic16/device.c,: structure PIC_device is made public and
3832 renamed to PIC16_device, the same for variable Pics which is renamed

3847 Documenting changes from previous commits.
3848 * configure.in (version 1.56),
3849 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3850 when generating output files to configure the pic16 library,
3851 but now I've commented it out, since gputils aren't installed in the
3852 SF compile farm, so library won't compile
3854 * device/lib/Makefile.in (version 1.56): initially I've added in
3855 target 'all' the prerequestive 'model-pic16' so it compiled the
3856 pic16 library, but now I've commented it out for the same reasons
3858 * added targets 'model-pic16' and 'objects-pic16' to compile the
3860 * added target 'port-specific-objects-pic16' to handle the
3861 generated libraries and copy them into the build/ directory
3862 * added target 'clean-intermediate-pic16' to clean intermediate
3863 files into pic16 directory
3864 * in target 'installdirs' added line to create directory pic16 in

3886 option so that it actually works. Made it specific to the z80, since
3887 the gbz80 doesn't have these kinds of I/O ports.
3889 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3891 * device/include/z180.h,

4110 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
4111 LEFT_OP (left shift)
4113 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4115 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4116 (default behaviour).
4118 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4120 A python script to validate compiler diagnostic messages. It can be
4121 used to verify that sdcc complains about bad c source code and
4122 gives a good location of the error.
4123 * support/valdiag/Makefile,
4124 * support/valdiag/valdiag.py,
4125 * support/valdiag/tests/*

4142 Bug reported from Jesus Calvino-Fraga
4144 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4146 * sdcc.spec: updated
4147 * device/include/Makefile.in: don't install CVS directories
4148 * device/lib/Makefile.in: added removal of CVS directories after install
4149 * doc/Makefile: fixed install, added local_icons
4150 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4151 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4152 * src/ds390/gen.c (genRightShift): fixed bug #870788
4153 * src/SDCCast.c (decorateType): fixed bug #870781
4155 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4157 PIC16 port related changes:
4158 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4159 added variable stackPos,
4161 * gen.c: genCall, assignResultValue: added support for
4162 pushing/retrieving function parameters to/from stack,
4163 genFunction,genEndFunction: setup stack frame for the
4165 genAddrOf: will be changed according to bug 863624
4167 * added files genutils.c and genutils.h which contain gen*
4168 debugged and optimised functions extracted from gen.c
4170 * glue.c: added variable 'externs' which holds extern symbols,
4171 pic16emitRegularMap: is modified to properly handle relocatable
4172 symbols under the new scheme,
4173 pic16createInterruptVect: is modified
4174 pic16printPublics: is modified to emit 'global' assembler directives,
4175 added pic16_printExterns to print extern symbols,
4176 pic16glue: initializes stack/frame pointer in the beginning of
4177 the assembly output. Temporary hack, will be corrected later,
4178 because gplink yet does not support stack and SDCC does not
4179 yet support a type of crt0.o object to create the final binary.
4181 * Removed many lines that contain 8051 legacy code.
4182 * The code is finally placed under a 'code' directive.
4183 * Added port specific options.
4185 * _process_pragma: simplified since now we do not need *special*
4186 include file to define SFR registers. But a separate header
4187 will be needed. This will be developed later.
4188 * _pic16_parseOptions: added, parses port specific options:
4189 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4190 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4191 --preplace-udata-with=
4193 * _pic16_setDefaultOptions: modified to initialize section names,
4194 but hack is temporarly out of order since it needs improvement.
4195 * _pic16_genAssemblerPreamble: configuration words are emitted by
4196 their address instead of their name. This part is incomplete and
4197 supports only the 18Fxx2 devices. Other devices will emit an error
4198 during assembly since they do not contain the same set of config
4200 * _pic16_genIVT: is modified,
4202 * pcode.c: added definitions for some hardware registers that are needed
4204 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4205 All PCI entries are updated. Now LFSR is supported.
4206 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4207 * added pic16_newpCodeOpLit2 to support instructions with
4208 two literal arguments
4209 * pic16_pCode2str: corrected code that emits assembler instructions
4210 with two literal operands and those that have an access bit modifier
4211 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4212 this fixes a bug which caused some labels to be lost, when an
4213 assembler directive was added, i.e. banksel,
4214 * pic16_FixRegisterBanking: improved logic that causes the insertion
4216 * InlineFunction: functions that are called once, are not any more
4217 inlined. This can be a port option in the future,
4219 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4221 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4222 hold the corresponding uninitialized symbols,
4223 * pic16_allocProcessorRegister: registers have explicit marked the
4225 * pic16_allocInternalRegister: registers are explicit marked as
4227 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4228 processing list, so bit registers were lost,
4231 * ralloc.h: added field 'accessBank' and original symbol operand
4232 in register definition,
4233 * removed the field isMapped from register definition,
4235 ** Several functions have been removed from various sources:
4236 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4237 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4238 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4239 pic16_assignRelocatableRegisters
4241 ** others have been introduced:
4242 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4243 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4245 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4247 * support/scripts/inc2h.pl: changed definition of BIT_AT
4248 to emit 'sbit at' instead of 'bit at'. This was a request.
4250 PIC16 port related preliminary changes:
4251 * gen.c: prefixed function popRegFromString with
4252 pic16_ and all references to it corrected
4253 * pcode.c: all pic16_pc_* hardware registers prefixed
4254 with underscore (_),
4255 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4256 * ralloc.c: newReg(): when register is REG_SFR then
4257 set address to rIdx,
4258 pic16_allocProcessorRegister(): marks register wasUsed=0
4259 pic16_writeUsedRegs(): added a call to assign processor
4260 registers via pic16_assignFixedRegisters
4262 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4264 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4265 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4266 variables in unused register banks. Also the SSEG is placed
4267 wherever there is enough space for it, and IDATA can be anywhere
4268 in internal RAM. For now compile using -Wl-Y[stack_size].
4269 The mem file is different for this option as well, since it
4270 makes no sense of talking about DSEG lenght.
4272 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4274 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4275 in certain cases, e.g. when ROM assignment, patch provided
4276 from Albert den Haan.
4278 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5283 copied from genNearPointerSet()
5284 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5285 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

5301 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5302 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5303 type for bits was changed. It resulted in bit variables becoming
5304 global, which is not permitted in PIC 14 assembly output.

5321 A few small changes that speed up the peephole optimizer.
5325 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5327 Try to make the peephole optimizer smarter by maintaining
5328 an association between the assembly source code and the
5329 iCodes that originated them. Put this information to use
5330 with a new peephole rule condition "notVolatile" so that
5331 the rules can be aggressive yet still safe.
5336 * src/mcs51/peeph.def
5338 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5342 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5343 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5344 if the left or right operand symbols have the accuse flag set.
5346 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5348 Changed the type of the result of the ! (NOT) operator to char;
5349 previously it returned the same type as the source. This allows
5350 us to eliminate all the genFloatNot functions (all of its target
5351 implementations were very buggy) since !float can use the same

5363 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5364 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5365 during interrupts. Ensure WSAVE is located at a shared bank address.
5366 2. Fixed page selection in some places
5367 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5368 the registers name strings.
5369 4. Fixed "signed / unsigned compare" compiler warnings.
5370 5. The PIC port manages its own allocation of the general purpose
5371 registers, but makes no attempt to reuse them. As a result when
5372 compiling it soon runs out of general purpose registers. Some
5373 additional code was added to the files pcode.c and device.c to walk
5374 through the function call tree and rename the registers so that they
5384 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5391 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5393 Made bitfield a distinct type from bit so that bitfields
5394 convert as per ANSI C and bits retain their traditional
5395 boolean style behaviour. Implemented bitfield support in
5403 * src/ds390/gen.c: bit v bitfield split
5404 * src/z80/gen.c: New support for bitfields
5405 * support/regression/tests/bitfields.c: reenabled z80,
5408 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5410 Rules 246.x, 247.x relate to bitfields, the others speed up
5411 access to xdata mapped I/O devices.
5413 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5415 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5417 Cleaned up genPackBits and genUnpackBits and added two helper
5418 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5419 for literal assignments in genPackBits (thanks to Frieder for
5425 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5427 Fixed bug #748310 (pointer to function type mishandled when the
5428 function name is omitted). Also fixed a SIGSEGV when a function
5429 attribute (reentrant, etc) is used on a non-function or on a
5430 function but misplaced before the parameter list.

5457 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5459 Made the constant following the "interrupt" keyword optional. If
5460 omitted, the function will not automatically be given an entry
5461 in the interrupt vector table (similar to #pragma NOIV, but
5462 less syntacticly kludgy). The interrupt number is also now
5463 range checked. Also fixed a bug in the high order bit example

5993 added if/endif conditional macros to remove options help
5994 messages from optionsTable when a port is not configured, added
5995 support for the PIc16 port in the ports table, when executing
5996 the compiler with no port specified on command line, a default
5997 port is selected with the new macro DEFAULT_PORT which is
5998 defined in port.h, in setDefaultOptions() linkOptions is removed
5999 from initialization assignment, since now it is a set,
6000 parseCmdLine uses setParseWithComma for linkOptions, in
6001 linkEdit() linkOptions are accessed with new function indexSet()
6002 which returns the i'th item of a set variable. See SDCCset.c, in
6003 linkEdit() when calling buildCmdLine(), added linkOptions as
6004 last argument. Now users can pass arguments to gplink via the
6005 -Wl option, main() uses pic16glue() to glue up pic16 programs

6019 gpasm complaining and test the linkage with gplink, _linkCmd and
6020 _asmCmd changed to be more gplink and gpasm friendly
6021 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6022 produced an error when parsed, peep rule 12 is added to utilize
6023 movff, but it is commented out since the pCode does not support
6024 yet a command with 2 address arguments
6026 2003-05-18 <johan AT balder>
6028 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6055 2003-05-11 Borut Razem <borut.razem AT siol.net>
6057 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

7063 * src/SDCCicode.c: fixed array add
7065 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7066 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7067 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7069 2003-01-04 <johan AT balder>
7071 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7073 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7074 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7076 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

7086 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7087 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7089 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7091 * in \sdcc\as\mcs51\ changed these files in order to create an
7092 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7093 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7094 following files to include the previous two files: aslink.dsp,
7095 Makefile.aslink, Makefile.bcc, and Makefile.in.
7097 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7098 .adb instead of .cdb
7100 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7102 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7103 value from option --iram-size.
7105 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7107 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7110 2002-09-18 <wiml AT hhhh.org>
7112 * SDCClrange.h: exposed setFromRange() and setToRange()
7113 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7114 packRegsForAccUse() (bug 542397)
7115 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7116 multiple times and emitting the fetch operations more than once
7117 added aopGetUsesAcc() function to allow binary operators to
7118 fetch their operands in the correct order; made genMinus() emit
7119 compact code for X = LITERAL - Y
7121 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7122 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7123 sprintf() in line 1267.
7125 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7126 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7129 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7130 Changes to aslink (All the changes are marked with 'JCF'):
7132 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7135 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7136 area BSEG. Also moves, if possible, the DATA area down into the internal
7137 ram so more space is available.
7139 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7142 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7143 not bytes. Function summary() which creates a memory usage summary
7144 file with extension .mem. Reports of overlaping stack and small stack
7145 size. If the space for the stack is less than 16 bytes aslink trows a
7148 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7149 the 8051. Option 'y' for memory summary output file.
7151 Changes to sdcc (All the changes are marked with 'JCF'):
7153 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7155 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7156 overlaying area for it (uses RegBankUsed[4]).
7158 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7159 bank zero as used by default. By default aslink locates the stack
7160 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7161 the creation of the .mem file. Delegates the allocation of data area
7162 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7163 the begining of the stack area to aslink.
7165 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7166 glue() in SDCCglue.c creates an area for it.
7168 2002-09-03 Borut Razem <borut.razem AT siol.net>
7169 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7170 sdcc/src/pic/glue.c:
7171 introduced atexit() handler for teporay files removal in case of
7172 errors, assertions, ...
7174 2002-08-29 Borut Razem <borut.razem AT siol.net>
7175 * sdcc/support/cpp2/auto-host_vc_in.h:
7176 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7177 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7178 Maybe there is a similar problem with BORLANDC? It should be checked!
7180 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7181 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7182 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7183 was not executed, and the compiler (cl) launched a warning:
7184 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7186 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7187 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7189 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7190 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7192 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7193 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7194 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7195 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7196 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7197 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7198 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7199 - added Release configuration in VS projects
7200 - review of compiler an linker options
7201 - VC .exe files are generated in bin_vc directory, not to interfere
7202 with binaries generated from other projects (cygwin, mingw, bcc ...)
7204 * sdcc/src/yacc.dsp: added
7206 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7207 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7208 and insert the version number definitions from .version
7210 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7212 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7213 added - genarate auto-host.h using auto-host_vc_in.h as template
7216 removed from CVS, generated automatically
7218 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7219 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7221 2002-08-11 Borut Razem <borut.razem AT siol.net>
7222 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7224 2002-08-10 Borut Razem <borut.razem AT siol.net>
7225 * src/SDCCmain.c (main):
7226 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7227 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7228 The consequence was that some temporary files were not removed.
7231 unification of code in functions tempfilename() and tempfile():
7232 function tempnam() is defined in Visual Studio 6.0 and .NET
7234 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7236 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7237 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7238 - removed compiler command line option /WX: Treats all warnings as errors
7239 - update a list of source files, included into the project
7241 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7242 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7243 changed project type to Generic Project so that can be correcly converted to VS.NET project
7245 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7247 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7249 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7251 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7252 added return 0 statements after assert() to make compiler happy
7254 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7255 added newline in the def file to keep MSC compiler satisfied
7257 * sdcc/src/z80/gen.c:
7258 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7259 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7260 - solved MSC error in function aopDump()
7262 * sdcc_vc.h: define PREFIX as "\\sdcc"
7264 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7265 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
7267 2002-06-22 Scott Dattalo <scott AT dattalo.com>
7268 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7269 - Rewrote the register banking algorithm.
7270 - Added pCode live-range analysis to registers (for now, only non-used and
7271 singly-used registers optimized away)
7273 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7275 * 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.
7277 2002-05-10 Scott Dattalo <scott AT dattalo.com>
7278 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
7280 2002-04-22 Michael Hope <michaelh AT vroom>
7282 * device/lib/z80/printf.c: Changed emitter to volatile to work around a pcall bug.
7284 * configure.in (DD_COPT): Added include support required for gbdk.

7300 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
7302 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
7304 2002-03-28 Johan Knol <johan AT balder>
7306 * src/SDCCval.c: fixed bug #532436
7308 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7310 Added "char *Processor" field to the port structure.
7313 Added -p option. Allows port dependent processor to be specified.
7316 Initialized the new field char *Processor field to NULL in all ports
7319 Compiler generated registers for interrupt context saving
7320 were not getting allocated.
7322 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7325 Fixed left shift. Will promote the left side of a left shift
7326 if a) left shifting more than size of operand or b) when assigned
7327 to something size > size of left side
7329 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7331 tons of changes. Register allocation has been
7332 rewritten. Added customization for the various PICs. Flow
7333 analysis is restructured. ...
7339 Added. device.c is a PIC port hack to accomodate variations
7342 2002-03-13 Michael Hope <michaelh AT vroom>
7344 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
7346 2002-03-04 johanknol <johanknol AT manik>
7348 * /src/SDCCval.c: fixed
7350 const unsigned char arr[][2] = { { 0, 1 } };
7351 t18.c:1: error: Initializer element is not constant
7353 2002-03-04 bela <bela AT manik>
7355 * /device/include/mcs51reg.h:
7356 ds89c420 register definition update
7358 2002-03-03 <johan AT FRIJA>

7437 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7439 * sdcc/src/SDCCloop.c:
7440 Previous fix was not good. basic blocks that have "break" or "return" are
7441 not really partof a loop , but live ranges used in these blocks should
7442 be live thru the entire loop, so set partOfLoop but don't add them to
7445 2002-02-21 <johan AT FRIJA>
7447 * src/SDCCcse.c: fixed bug #514308
7449 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
7452 Fixed BUG #519583. If a conditional block ended in a return/break
7453 statement inside a loop, it was not being considered part of the loop.
7455 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7457 2002-02-10 Karl Bongers <karl AT turbobit.com>
7460 Fixed up SDCDB debugger somewhat. Updated debugger/README
