1 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
4 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
6 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
8 * device/lib/printf_large.c: removed inline assembly for portability and
9 readability. Use printf_fast if speed or size are more important.
10 * src/pic16/gen.c: removed conditions around use of DEBUGpc
11 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
13 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
15 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
16 prevent compiler warning
18 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
20 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
21 moved to level 0 and declared as static. Also they are explicit
22 placed in access bank. This was necessery because some times they
23 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
24 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
25 optimizations. Currently only compare to unsigned char is implemented,
26 * src/pic16/gen.c: added fReturnIdx array,
27 * (struct resolvedIfx) is moved to gen.h and made public,
28 * (struct _G): added sregsAlloc and sregsAllocSet fields,
29 * (aopForSym): added an optimization to directly store in stack of
30 the operand of a SEND iCode,
31 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
32 but as registers instead (AOP_REG) using the fReturnIdx array,
33 * (pic16_freeAsmop): remove the freed register from the
35 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
37 * (pic16_popGetTempRegCond): changed function prototype, now
38 function takes also a bitVector argument v which holds the current
39 set of registers that are allocated for stack access by aopForSym,
40 registers allocated in aopForSym for accessing stack symbols are not
41 any more part of the functions usedRegs field,
42 * (genCall): some times aopOp is called for a stack variable to be
43 send, aopForSym might perform the push, if this is true make sure
44 that genCall doesn't push the variable twice by testing _G.resDirect,
45 * (genFunction): changed testing for unspecified interrupt number
46 from 256 to INTNO_UNSPEC,
47 * modified selection scheme of frame pointer generation. Previously
48 if function did use local registers a frame pointer was generated,
49 now a frame pointer is generated only if function has arguments
50 (that need PLUSW2 register access), or has stack arguments, or the
51 compiler is not instructed to omit the frame pointer,
52 * (genEndFunction): before restoring local registers that were saved
53 in the function preamble, also restore the registers that *might*
54 have been allocated for stack access,
55 * (genRet): removed some old comments,
56 * (genCmp, the active (RN's) version): added a call to the
57 pic16_genCmp_special function to perform the compare with a more
58 robust and optimized way,
59 * (genInline): a feature has been added in inline code generation,
60 which allows a wildcard variable substitution when writing inline
61 assembly. Code is incomplete and experimental therefore undocumented,
62 * (genCast): changed order of aopOp for result and right to allow
63 aopForSym to directly load the result if possible,
64 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
65 perform an optimized compare on some selected special occasions,
66 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
67 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
68 generate an IVT any more,
69 * src/pic16/main.c (pic16_optionsTable): added command line option
71 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
72 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
74 * src/pic16/NOTES: Raphael Neider added in list of active developers
75 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
76 jumptable_end to prevent bug #,
77 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
78 inCond and outCond fields,
79 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
80 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
81 turn off register spilling,
82 * (packRegsForOneUse): synced with other ports' versions although it
83 is not used currently,
84 * (pic16_packRegisters): added an optimization while reading
85 structure bitfields, some registers may be saved (malloc code is
86 decreased by 80 bytes)
88 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
90 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
91 left is a bitfield, if yes, then don't optimize assignment. Perhaps
92 this can be optimized more?
94 2005-03-10 Raphael Neider <rneider AT web.de>
96 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
97 genNearPointerGet): (hopefully) fixed access to bitfields via
98 pointers (p->bitN = x; and x = p->bitN; failed)
100 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
102 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

732 Adding support for replacing ljmps with sjmps in jumptables
733 generated for switch statements. For now you need to set the
734 environment variable SDCC_SJMP_JUMPTABLE to enable this.
735 Now 4 algorithms for mcs51 jumptable generation are used:
736 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

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

3819 loaded with the linker search paths (-L arguments) and the libraries
3820 to be linked with the current source (-l arguments). Changes
3821 currently will affect only the pic16 port.
3822 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3823 include path the port specific paths and port specific libraries,
3824 * gplink command now contains the $3 argument,
3825 * src/pic16/device.h,
3826 * src/pic16/device.c,: structure PIC_device is made public and

3842 Documenting changes from previous commits.
3843 * configure.in (version 1.56),
3844 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3845 when generating output files to configure the pic16 library,
3846 but now I've commented it out, since gputils aren't installed in the
3847 SF compile farm, so library won't compile
3849 * device/lib/Makefile.in (version 1.56): initially I've added in
3850 target 'all' the prerequestive 'model-pic16' so it compiled the
3851 pic16 library, but now I've commented it out for the same reasons
3853 * added targets 'model-pic16' and 'objects-pic16' to compile the
3855 * added target 'port-specific-objects-pic16' to handle the
3856 generated libraries and copy them into the build/ directory
3857 * added target 'clean-intermediate-pic16' to clean intermediate
3858 files into pic16 directory
3859 * in target 'installdirs' added line to create directory pic16 in

4056 needLinkerScript flag
4058 * src/pic16/gen.c (genAddrOf): fixed bug #863624
4059 * src/pic/glue.c: added variable udata_section_name to
4060 override default uninitialized data segment definition for
4061 devices only with SHAREBANK memory (reported from Erik Epetrich)
4062 * (pic14emitOverlay): modified to emit a commented overlay segment
4063 directive when no overlay data exist
4064 * (picglue): modified to emit uninitialized data segment
4065 according to udata_section_name

4069 * modified _linkCmd and _asmCmd to include compiler passed
4070 arguments via -W option
4071 * src/pic16/main.c: added $l in _asmCmd, changed extension for
4072 object file from '.rel' to '.o' in port->linker structure,
4073 changed size of fptr from 2 to 3 in port structure
4075 2004-01-07 Borut Razem <borut.razem AT siol.net>
4077 * support/scripts/sdcc.nsi: update PATH
4078 * support/scripts/sdcc.ico: craeted

4094 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4096 * as/mcs51/lkmain.c: Help about -Y option
4097 * as/mcs51/lkarea.c: Fixed gcc warnings
4099 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4101 * src/SDCCval.c (valShift): changed from 16 to 32 bit shift count,
4103 * support/valdiag/tests/overflow.c: added
4104 * src/SDCCast.c (decorateType),
4105 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
4106 LEFT_OP (left shift)
4108 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4110 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4111 (default behaviour).
4113 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4115 A python script to validate compiler diagnostic messages. It can be
4116 used to verify that sdcc complains about bad c source code and
4117 gives a good location of the error.
4118 * support/valdiag/Makefile,
4119 * support/valdiag/valdiag.py,
4120 * support/valdiag/tests/*
4122 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4124 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

4135 * src/common.h: added ifndef/define/endif macros
4136 around the header file.
4137 Bug reported from Jesus Calvino-Fraga
4139 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4141 * sdcc.spec: updated
4142 * device/include/Makefile.in: don't install CVS directories
4143 * device/lib/Makefile.in: added removal of CVS directories after install
4144 * doc/Makefile: fixed install, added local_icons
4145 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4146 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4147 * src/ds390/gen.c (genRightShift): fixed bug #870788
4148 * src/SDCCast.c (decorateType): fixed bug #870781
4150 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4152 PIC16 port related changes:
4153 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4154 added variable stackPos,
4156 * gen.c: genCall, assignResultValue: added support for
4157 pushing/retrieving function parameters to/from stack,
4158 genFunction,genEndFunction: setup stack frame for the
4160 genAddrOf: will be changed according to bug 863624
4162 * added files genutils.c and genutils.h which contain gen*
4163 debugged and optimised functions extracted from gen.c
4165 * glue.c: added variable 'externs' which holds extern symbols,
4166 pic16emitRegularMap: is modified to properly handle relocatable
4167 symbols under the new scheme,
4168 pic16createInterruptVect: is modified
4169 pic16printPublics: is modified to emit 'global' assembler directives,
4170 added pic16_printExterns to print extern symbols,
4171 pic16glue: initializes stack/frame pointer in the beginning of
4172 the assembly output. Temporary hack, will be corrected later,
4173 because gplink yet does not support stack and SDCC does not
4174 yet support a type of crt0.o object to create the final binary.
4176 * Removed many lines that contain 8051 legacy code.
4177 * The code is finally placed under a 'code' directive.
4178 * Added port specific options.
4180 * _process_pragma: simplified since now we do not need *special*
4181 include file to define SFR registers. But a separate header
4182 will be needed. This will be developed later.
4183 * _pic16_parseOptions: added, parses port specific options:
4184 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4185 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4186 --preplace-udata-with=
4188 * _pic16_setDefaultOptions: modified to initialize section names,
4189 but hack is temporarly out of order since it needs improvement.
4190 * _pic16_genAssemblerPreamble: configuration words are emitted by
4191 their address instead of their name. This part is incomplete and
4192 supports only the 18Fxx2 devices. Other devices will emit an error
4193 during assembly since they do not contain the same set of config
4195 * _pic16_genIVT: is modified,
4197 * pcode.c: added definitions for some hardware registers that are needed
4199 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4200 All PCI entries are updated. Now LFSR is supported.
4201 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4202 * added pic16_newpCodeOpLit2 to support instructions with
4203 two literal arguments
4204 * pic16_pCode2str: corrected code that emits assembler instructions
4205 with two literal operands and those that have an access bit modifier
4206 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4207 this fixes a bug which caused some labels to be lost, when an
4208 assembler directive was added, i.e. banksel,
4209 * pic16_FixRegisterBanking: improved logic that causes the insertion
4211 * InlineFunction: functions that are called once, are not any more
4212 inlined. This can be a port option in the future,
4214 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4216 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4217 hold the corresponding uninitialized symbols,
4218 * pic16_allocProcessorRegister: registers have explicit marked the
4220 * pic16_allocInternalRegister: registers are explicit marked as
4222 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4223 processing list, so bit registers were lost,
4226 * ralloc.h: added field 'accessBank' and original symbol operand
4227 in register definition,
4228 * removed the field isMapped from register definition,
4230 ** Several functions have been removed from various sources:
4231 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4232 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4233 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4234 pic16_assignRelocatableRegisters
4236 ** others have been introduced:
4237 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4238 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4240 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4242 * support/scripts/inc2h.pl: changed definition of BIT_AT
4243 to emit 'sbit at' instead of 'bit at'. This was a request.
4245 PIC16 port related preliminary changes:
4246 * gen.c: prefixed function popRegFromString with
4247 pic16_ and all references to it corrected
4248 * pcode.c: all pic16_pc_* hardware registers prefixed
4249 with underscore (_),
4250 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4251 * ralloc.c: newReg(): when register is REG_SFR then
4252 set address to rIdx,
4253 pic16_allocProcessorRegister(): marks register wasUsed=0
4254 pic16_writeUsedRegs(): added a call to assign processor
4255 registers via pic16_assignFixedRegisters
4257 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4259 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4260 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4261 variables in unused register banks. Also the SSEG is placed
4262 wherever there is enough space for it, and IDATA can be anywhere
4263 in internal RAM. For now compile using -Wl-Y[stack_size].
4264 The mem file is different for this option as well, since it
4265 makes no sense of talking about DSEG lenght.
4267 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4269 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4270 in certain cases, e.g. when ROM assignment, patch provided
4271 from Albert den Haan.

4512 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4514 * src/SDCCast.c (decorateType): disabled a transformation I added in
4515 revision 1.188 (access to fields of a structure at an absolute address);
4516 it breaks with bitfields, extern declarations, and gcse analysis.
4517 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it

5275 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5276 fetching of the pointer
5277 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5278 copied from genNearPointerSet()
5279 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5280 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

5296 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5297 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5298 type for bits was changed. It resulted in bit variables becoming
5299 global, which is not permitted in PIC 14 assembly output.

5316 A few small changes that speed up the peephole optimizer.
5320 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5322 Try to make the peephole optimizer smarter by maintaining
5323 an association between the assembly source code and the
5324 iCodes that originated them. Put this information to use
5325 with a new peephole rule condition "notVolatile" so that
5326 the rules can be aggressive yet still safe.
5331 * src/mcs51/peeph.def
5333 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5337 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5338 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5339 if the left or right operand symbols have the accuse flag set.
5341 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5343 Changed the type of the result of the ! (NOT) operator to char;
5344 previously it returned the same type as the source. This allows
5345 us to eliminate all the genFloatNot functions (all of its target
5346 implementations were very buggy) since !float can use the same

5358 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5359 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5360 during interrupts. Ensure WSAVE is located at a shared bank address.
5361 2. Fixed page selection in some places
5362 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5363 the registers name strings.
5364 4. Fixed "signed / unsigned compare" compiler warnings.
5365 5. The PIC port manages its own allocation of the general purpose
5366 registers, but makes no attempt to reuse them. As a result when
5367 compiling it soon runs out of general purpose registers. Some
5368 additional code was added to the files pcode.c and device.c to walk
5369 through the function call tree and rename the registers so that they
5379 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5386 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5388 Made bitfield a distinct type from bit so that bitfields
5389 convert as per ANSI C and bits retain their traditional
5390 boolean style behaviour. Implemented bitfield support in
5398 * src/ds390/gen.c: bit v bitfield split
5399 * src/z80/gen.c: New support for bitfields
5400 * support/regression/tests/bitfields.c: reenabled z80,
5403 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5405 Rules 246.x, 247.x relate to bitfields, the others speed up
5406 access to xdata mapped I/O devices.
5408 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5410 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5412 Cleaned up genPackBits and genUnpackBits and added two helper
5413 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5414 for literal assignments in genPackBits (thanks to Frieder for
5420 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5422 Fixed bug #748310 (pointer to function type mishandled when the
5423 function name is omitted). Also fixed a SIGSEGV when a function
5424 attribute (reentrant, etc) is used on a non-function or on a
5425 function but misplaced before the parameter list.

5452 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5454 Made the constant following the "interrupt" keyword optional. If
5455 omitted, the function will not automatically be given an entry
5456 in the interrupt vector table (similar to #pragma NOIV, but
5457 less syntacticly kludgy). The interrupt number is also now
5458 range checked. Also fixed a bug in the high order bit example

5988 added if/endif conditional macros to remove options help
5989 messages from optionsTable when a port is not configured, added
5990 support for the PIc16 port in the ports table, when executing
5991 the compiler with no port specified on command line, a default
5992 port is selected with the new macro DEFAULT_PORT which is
5993 defined in port.h, in setDefaultOptions() linkOptions is removed
5994 from initialization assignment, since now it is a set,
5995 parseCmdLine uses setParseWithComma for linkOptions, in
5996 linkEdit() linkOptions are accessed with new function indexSet()
5997 which returns the i'th item of a set variable. See SDCCset.c, in
5998 linkEdit() when calling buildCmdLine(), added linkOptions as
5999 last argument. Now users can pass arguments to gplink via the
6000 -Wl option, main() uses pic16glue() to glue up pic16 programs

6014 gpasm complaining and test the linkage with gplink, _linkCmd and
6015 _asmCmd changed to be more gplink and gpasm friendly
6016 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6017 produced an error when parsed, peep rule 12 is added to utilize
6018 movff, but it is commented out since the pCode does not support
6019 yet a command with 2 address arguments
6021 2003-05-18 <johan AT balder>
6023 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7058 * src/SDCCicode.c: fixed array add
7060 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7061 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7062 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7064 2003-01-04 <johan AT balder>
7066 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7068 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7069 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7071 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

7081 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7082 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7084 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7086 * in \sdcc\as\mcs51\ changed these files in order to create an
7087 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7088 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7089 following files to include the previous two files: aslink.dsp,
7090 Makefile.aslink, Makefile.bcc, and Makefile.in.
7092 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7093 .adb instead of .cdb
7095 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7097 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7098 value from option --iram-size.
7100 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7102 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7105 2002-09-18 <wiml AT hhhh.org>
7107 * SDCClrange.h: exposed setFromRange() and setToRange()
7108 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7109 packRegsForAccUse() (bug 542397)
7110 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7111 multiple times and emitting the fetch operations more than once
7112 added aopGetUsesAcc() function to allow binary operators to
7113 fetch their operands in the correct order; made genMinus() emit
7114 compact code for X = LITERAL - Y
7116 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7117 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7118 sprintf() in line 1267.
7120 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7121 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7124 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7125 Changes to aslink (All the changes are marked with 'JCF'):
7127 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7130 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7131 area BSEG. Also moves, if possible, the DATA area down into the internal
7132 ram so more space is available.
7134 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7137 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7138 not bytes. Function summary() which creates a memory usage summary
7139 file with extension .mem. Reports of overlaping stack and small stack
7140 size. If the space for the stack is less than 16 bytes aslink trows a
7143 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7144 the 8051. Option 'y' for memory summary output file.
7146 Changes to sdcc (All the changes are marked with 'JCF'):
7148 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7150 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7151 overlaying area for it (uses RegBankUsed[4]).
7153 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7154 bank zero as used by default. By default aslink locates the stack
7155 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7156 the creation of the .mem file. Delegates the allocation of data area
7157 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7158 the begining of the stack area to aslink.
7160 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7161 glue() in SDCCglue.c creates an area for it.
7163 2002-09-03 Borut Razem <borut.razem AT siol.net>
7164 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7165 sdcc/src/pic/glue.c:
7166 introduced atexit() handler for teporay files removal in case of
7167 errors, assertions, ...
7169 2002-08-29 Borut Razem <borut.razem AT siol.net>
7170 * sdcc/support/cpp2/auto-host_vc_in.h:
7171 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7172 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7173 Maybe there is a similar problem with BORLANDC? It should be checked!
7175 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7176 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7177 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7178 was not executed, and the compiler (cl) launched a warning:
7179 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7181 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7182 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7184 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7185 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7187 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7188 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7189 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7190 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7191 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7192 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7193 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7194 - added Release configuration in VS projects
7195 - review of compiler an linker options
7196 - VC .exe files are generated in bin_vc directory, not to interfere
7197 with binaries generated from other projects (cygwin, mingw, bcc ...)
7199 * sdcc/src/yacc.dsp: added
7201 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7202 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7203 and insert the version number definitions from .version
7205 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7207 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7208 added - genarate auto-host.h using auto-host_vc_in.h as template
7211 removed from CVS, generated automatically
7213 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7214 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7216 2002-08-11 Borut Razem <borut.razem AT siol.net>
7217 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7219 2002-08-10 Borut Razem <borut.razem AT siol.net>
7220 * src/SDCCmain.c (main):
7221 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7222 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7223 The consequence was that some temporary files were not removed.
7226 unification of code in functions tempfilename() and tempfile():
7227 function tempnam() is defined in Visual Studio 6.0 and .NET
7229 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7231 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7232 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7233 - removed compiler command line option /WX: Treats all warnings as errors
7234 - update a list of source files, included into the project
7236 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7237 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7238 changed project type to Generic Project so that can be correcly converted to VS.NET project
7240 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7242 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7244 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7246 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7247 added return 0 statements after assert() to make compiler happy
7249 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7250 added newline in the def file to keep MSC compiler satisfied
7252 * sdcc/src/z80/gen.c:
7253 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7254 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7255 - solved MSC error in function aopDump()
7257 * sdcc_vc.h: define PREFIX as "\\sdcc"
7259 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7260 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
7262 2002-06-22 Scott Dattalo <scott AT dattalo.com>
7263 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7264 - Rewrote the register banking algorithm.
7265 - Added pCode live-range analysis to registers (for now, only non-used and
7266 singly-used registers optimized away)
7268 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7270 * 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.
7272 2002-05-10 Scott Dattalo <scott AT dattalo.com>
7273 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
7275 2002-04-22 Michael Hope <michaelh AT vroom>

7295 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
7297 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
7299 2002-03-28 Johan Knol <johan AT balder>
7301 * src/SDCCval.c: fixed bug #532436
7303 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7305 Added "char *Processor" field to the port structure.
7308 Added -p option. Allows port dependent processor to be specified.
7311 Initialized the new field char *Processor field to NULL in all ports
7314 Compiler generated registers for interrupt context saving
7315 were not getting allocated.
7317 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7320 Fixed left shift. Will promote the left side of a left shift
7321 if a) left shifting more than size of operand or b) when assigned
7322 to something size > size of left side
7324 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7326 tons of changes. Register allocation has been
7327 rewritten. Added customization for the various PICs. Flow
7328 analysis is restructured. ...
7334 Added. device.c is a PIC port hack to accomodate variations
7337 2002-03-13 Michael Hope <michaelh AT vroom>
7339 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
7341 2002-03-04 johanknol <johanknol AT manik>
7343 * /src/SDCCval.c: fixed
7345 const unsigned char arr[][2] = { { 0, 1 } };
7346 t18.c:1: error: Initializer element is not constant
7348 2002-03-04 bela <bela AT manik>
7350 * /device/include/mcs51reg.h:
7351 ds89c420 register definition update
7353 2002-03-03 <johan AT FRIJA>

7432 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7434 * sdcc/src/SDCCloop.c:
7435 Previous fix was not good. basic blocks that have "break" or "return" are
7436 not really partof a loop , but live ranges used in these blocks should
7437 be live thru the entire loop, so set partOfLoop but don't add them to
7440 2002-02-21 <johan AT FRIJA>
7442 * src/SDCCcse.c: fixed bug #514308
7444 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
7447 Fixed BUG #519583. If a conditional block ended in a return/break
7448 statement inside a loop, it was not being considered part of the loop.
7450 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7452 2002-02-10 Karl Bongers <karl AT turbobit.com>
7455 Fixed up SDCDB debugger somewhat. Updated debugger/README
7456 with lots of comments and notes.
7458 * device/examples/test2.c:
