1 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3 * device/include/stdint.h: added
4 * device/lib/abs.c: added
5 * device/lib/labs.c: added
6 * device/include/stdlib.h: added abs() and labs() prototypes
7 * device/lib/libsdcc.lib: added abs and labs
8 * device/include/float.h,
10 * device/lib/printf_fast.c,
11 * device/lib/printf_tiny.c: updated comments
13 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
15 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
18 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
20 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
21 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
23 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
25 * device/lib/printf_large.c: removed inline assembly for portability and
26 readability. Use printf_fast if speed or size are more important.
27 * src/pic16/gen.c: removed conditions around use of DEBUGpc
28 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
30 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
32 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
33 prevent compiler warning
35 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
37 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
38 moved to level 0 and declared as static. Also they are explicit
39 placed in access bank. This was necessery because some times they
40 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
41 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
42 optimizations. Currently only compare to unsigned char is implemented,
43 * src/pic16/gen.c: added fReturnIdx array,
44 * (struct resolvedIfx) is moved to gen.h and made public,
45 * (struct _G): added sregsAlloc and sregsAllocSet fields,
46 * (aopForSym): added an optimization to directly store in stack of
47 the operand of a SEND iCode,
48 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
49 but as registers instead (AOP_REG) using the fReturnIdx array,
50 * (pic16_freeAsmop): remove the freed register from the
52 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
54 * (pic16_popGetTempRegCond): changed function prototype, now
55 function takes also a bitVector argument v which holds the current
56 set of registers that are allocated for stack access by aopForSym,
57 registers allocated in aopForSym for accessing stack symbols are not
58 any more part of the functions usedRegs field,
59 * (genCall): some times aopOp is called for a stack variable to be
60 send, aopForSym might perform the push, if this is true make sure
61 that genCall doesn't push the variable twice by testing _G.resDirect,
62 * (genFunction): changed testing for unspecified interrupt number
63 from 256 to INTNO_UNSPEC,
64 * modified selection scheme of frame pointer generation. Previously
65 if function did use local registers a frame pointer was generated,
66 now a frame pointer is generated only if function has arguments
67 (that need PLUSW2 register access), or has stack arguments, or the
68 compiler is not instructed to omit the frame pointer,
69 * (genEndFunction): before restoring local registers that were saved
70 in the function preamble, also restore the registers that *might*
71 have been allocated for stack access,
72 * (genRet): removed some old comments,
73 * (genCmp, the active (RN's) version): added a call to the
74 pic16_genCmp_special function to perform the compare with a more
75 robust and optimized way,
76 * (genInline): a feature has been added in inline code generation,
77 which allows a wildcard variable substitution when writing inline
78 assembly. Code is incomplete and experimental therefore undocumented,
79 * (genCast): changed order of aopOp for result and right to allow
80 aopForSym to directly load the result if possible,
81 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
82 perform an optimized compare on some selected special occasions,
83 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
84 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
85 generate an IVT any more,
86 * src/pic16/main.c (pic16_optionsTable): added command line option
88 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
89 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
91 * src/pic16/NOTES: Raphael Neider added in list of active developers
92 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
93 jumptable_end to prevent bug #,
94 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
95 inCond and outCond fields,
96 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
97 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
98 turn off register spilling,
99 * (packRegsForOneUse): synced with other ports' versions although it
100 is not used currently,
101 * (pic16_packRegisters): added an optimization while reading
102 structure bitfields, some registers may be saved (malloc code is
103 decreased by 80 bytes)
105 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
107 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
108 left is a bitfield, if yes, then don't optimize assignment. Perhaps
109 this can be optimized more?
111 2005-03-10 Raphael Neider <rneider AT web.de>
113 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
114 genNearPointerGet): (hopefully) fixed access to bitfields via
115 pointers (p->bitN = x; and x = p->bitN; failed)

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

3833 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3835 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3836 loaded with the linker search paths (-L arguments) and the libraries
3837 to be linked with the current source (-l arguments). Changes
3838 currently will affect only the pic16 port.
3839 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3840 include path the port specific paths and port specific libraries,
3841 * gplink command now contains the $3 argument,
3842 * src/pic16/device.h,
3843 * src/pic16/device.c,: structure PIC_device is made public and
3844 renamed to PIC16_device, the same for variable Pics which is renamed

3859 Documenting changes from previous commits.
3860 * configure.in (version 1.56),
3861 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3862 when generating output files to configure the pic16 library,
3863 but now I've commented it out, since gputils aren't installed in the
3864 SF compile farm, so library won't compile
3866 * device/lib/Makefile.in (version 1.56): initially I've added in
3867 target 'all' the prerequestive 'model-pic16' so it compiled the
3868 pic16 library, but now I've commented it out for the same reasons
3870 * added targets 'model-pic16' and 'objects-pic16' to compile the
3872 * added target 'port-specific-objects-pic16' to handle the
3873 generated libraries and copy them into the build/ directory
3874 * added target 'clean-intermediate-pic16' to clean intermediate
3875 files into pic16 directory
3876 * in target 'installdirs' added line to create directory pic16 in

3897 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3898 option so that it actually works. Made it specific to the z80, since
3899 the gbz80 doesn't have these kinds of I/O ports.
3901 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3927 via literal number. The symbol is placed in the corresponding
3928 position of the data ram
3929 * (pic16_dump_section): relocatable and absolute uninitialized
3930 data are now emitted in sorted order to reduce section naming,
3931 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3932 weren't marked as being in the access bank,

4125 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4127 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4128 (default behaviour).
4130 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4132 A python script to validate compiler diagnostic messages. It can be
4133 used to verify that sdcc complains about bad c source code and
4134 gives a good location of the error.
4135 * support/valdiag/Makefile,
4136 * support/valdiag/valdiag.py,
4137 * support/valdiag/tests/*

4154 Bug reported from Jesus Calvino-Fraga
4156 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4158 * sdcc.spec: updated
4159 * device/include/Makefile.in: don't install CVS directories
4160 * device/lib/Makefile.in: added removal of CVS directories after install
4161 * doc/Makefile: fixed install, added local_icons
4162 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4163 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4164 * src/ds390/gen.c (genRightShift): fixed bug #870788

4167 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4169 PIC16 port related changes:
4170 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4171 added variable stackPos,
4173 * gen.c: genCall, assignResultValue: added support for
4174 pushing/retrieving function parameters to/from stack,
4175 genFunction,genEndFunction: setup stack frame for the
4177 genAddrOf: will be changed according to bug 863624
4179 * added files genutils.c and genutils.h which contain gen*
4180 debugged and optimised functions extracted from gen.c
4182 * glue.c: added variable 'externs' which holds extern symbols,
4183 pic16emitRegularMap: is modified to properly handle relocatable
4184 symbols under the new scheme,
4185 pic16createInterruptVect: is modified
4186 pic16printPublics: is modified to emit 'global' assembler directives,
4187 added pic16_printExterns to print extern symbols,
4188 pic16glue: initializes stack/frame pointer in the beginning of
4189 the assembly output. Temporary hack, will be corrected later,
4190 because gplink yet does not support stack and SDCC does not
4191 yet support a type of crt0.o object to create the final binary.
4193 * Removed many lines that contain 8051 legacy code.
4194 * The code is finally placed under a 'code' directive.
4195 * Added port specific options.
4197 * _process_pragma: simplified since now we do not need *special*
4198 include file to define SFR registers. But a separate header
4199 will be needed. This will be developed later.
4200 * _pic16_parseOptions: added, parses port specific options:
4201 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4202 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4203 --preplace-udata-with=
4205 * _pic16_setDefaultOptions: modified to initialize section names,
4206 but hack is temporarly out of order since it needs improvement.
4207 * _pic16_genAssemblerPreamble: configuration words are emitted by
4208 their address instead of their name. This part is incomplete and
4209 supports only the 18Fxx2 devices. Other devices will emit an error
4210 during assembly since they do not contain the same set of config
4212 * _pic16_genIVT: is modified,
4214 * pcode.c: added definitions for some hardware registers that are needed
4216 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4217 All PCI entries are updated. Now LFSR is supported.
4218 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4219 * added pic16_newpCodeOpLit2 to support instructions with
4220 two literal arguments
4221 * pic16_pCode2str: corrected code that emits assembler instructions
4222 with two literal operands and those that have an access bit modifier
4223 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4224 this fixes a bug which caused some labels to be lost, when an
4225 assembler directive was added, i.e. banksel,
4226 * pic16_FixRegisterBanking: improved logic that causes the insertion
4228 * InlineFunction: functions that are called once, are not any more
4229 inlined. This can be a port option in the future,
4231 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4233 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4234 hold the corresponding uninitialized symbols,
4235 * pic16_allocProcessorRegister: registers have explicit marked the
4237 * pic16_allocInternalRegister: registers are explicit marked as
4239 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4240 processing list, so bit registers were lost,
4243 * ralloc.h: added field 'accessBank' and original symbol operand
4244 in register definition,
4245 * removed the field isMapped from register definition,
4247 ** Several functions have been removed from various sources:
4248 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4249 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4250 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4251 pic16_assignRelocatableRegisters
4253 ** others have been introduced:
4254 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4255 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4257 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4259 * support/scripts/inc2h.pl: changed definition of BIT_AT
4260 to emit 'sbit at' instead of 'bit at'. This was a request.
4262 PIC16 port related preliminary changes:
4263 * gen.c: prefixed function popRegFromString with
4264 pic16_ and all references to it corrected
4265 * pcode.c: all pic16_pc_* hardware registers prefixed
4266 with underscore (_),
4267 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4268 * ralloc.c: newReg(): when register is REG_SFR then
4269 set address to rIdx,
4270 pic16_allocProcessorRegister(): marks register wasUsed=0
4271 pic16_writeUsedRegs(): added a call to assign processor
4272 registers via pic16_assignFixedRegisters
4274 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4276 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4277 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4278 variables in unused register banks. Also the SSEG is placed
4279 wherever there is enough space for it, and IDATA can be anywhere
4280 in internal RAM. For now compile using -Wl-Y[stack_size].
4281 The mem file is different for this option as well, since it
4282 makes no sense of talking about DSEG lenght.
4284 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4286 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4287 in certain cases, e.g. when ROM assignment, patch provided
4288 from Albert den Haan.

5293 fetching of the pointer
5294 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5295 copied from genNearPointerSet()
5296 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5297 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5298 If they pop r0/r1 they must be called in the opposite order than aopOp().
5299 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5300 (resp. --stack-auto), prepared for --xstack

5311 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5313 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5314 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5315 type for bits was changed. It resulted in bit variables becoming
5316 global, which is not permitted in PIC 14 assembly output.
5318 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5320 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5333 A few small changes that speed up the peephole optimizer.
5337 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5339 Try to make the peephole optimizer smarter by maintaining
5340 an association between the assembly source code and the
5341 iCodes that originated them. Put this information to use
5342 with a new peephole rule condition "notVolatile" so that
5343 the rules can be aggressive yet still safe.
5348 * src/mcs51/peeph.def
5350 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5354 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5355 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5356 if the left or right operand symbols have the accuse flag set.
5358 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5360 Changed the type of the result of the ! (NOT) operator to char;
5361 previously it returned the same type as the source. This allows
5362 us to eliminate all the genFloatNot functions (all of its target
5363 implementations were very buggy) since !float can use the same
5366 * src/SDCCicode.c (ast2iCode): ! returns char
5367 * src/mcs51/gen.c (genNot, genNotFloat),
5368 * src/ds390/gen.c (genNot, genNotFloat),
5369 * src/z80/gen.c (genNot, genNotFloat),
5370 * src/pic/gen.c (genNot, genNotFloat),

5373 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
5375 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5376 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5377 during interrupts. Ensure WSAVE is located at a shared bank address.
5378 2. Fixed page selection in some places
5379 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5380 the registers name strings.
5381 4. Fixed "signed / unsigned compare" compiler warnings.
5382 5. The PIC port manages its own allocation of the general purpose
5383 registers, but makes no attempt to reuse them. As a result when
5384 compiling it soon runs out of general purpose registers. Some
5385 additional code was added to the files pcode.c and device.c to walk
5386 through the function call tree and rename the registers so that they
5396 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5397 genPlus() & genMinus() when the result is the same as left or right

5403 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5405 Made bitfield a distinct type from bit so that bitfields
5406 convert as per ANSI C and bits retain their traditional
5407 boolean style behaviour. Implemented bitfield support in
5415 * src/ds390/gen.c: bit v bitfield split
5416 * src/z80/gen.c: New support for bitfields
5417 * support/regression/tests/bitfields.c: reenabled z80,
5420 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5422 Rules 246.x, 247.x relate to bitfields, the others speed up
5423 access to xdata mapped I/O devices.
5425 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5427 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5429 Cleaned up genPackBits and genUnpackBits and added two helper
5430 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5431 for literal assignments in genPackBits (thanks to Frieder for
5437 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5439 Fixed bug #748310 (pointer to function type mishandled when the
5440 function name is omitted). Also fixed a SIGSEGV when a function
5441 attribute (reentrant, etc) is used on a non-function or on a
5442 function but misplaced before the parameter list.
5444 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5446 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5447 * support/Util/SDCCerr.h,
5448 * support/Util/SDCCerr.c: Added func attr misuse error msg
5450 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
5452 Fixed bug #787649 by anonymous
5453 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

5469 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5471 Made the constant following the "interrupt" keyword optional. If
5472 omitted, the function will not automatically be given an entry
5473 in the interrupt vector table (similar to #pragma NOIV, but
5474 less syntacticly kludgy). The interrupt number is also now
5475 range checked. Also fixed a bug in the high order bit example

5486 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
5488 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
5489 * src/SDCCicode.c (operandOperation): rewritten some ops
5490 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5491 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5493 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5494 be re-activated by defining REDUCE_LITERALS)
5495 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5496 unsigned, but are signed by default
5497 * src/SDCCval.c (constVal): rearranged
5498 * src/SDCCval.c (valMod): preliminary fix
5499 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6005 added if/endif conditional macros to remove options help
6006 messages from optionsTable when a port is not configured, added
6007 support for the PIc16 port in the ports table, when executing
6008 the compiler with no port specified on command line, a default
6009 port is selected with the new macro DEFAULT_PORT which is
6010 defined in port.h, in setDefaultOptions() linkOptions is removed
6011 from initialization assignment, since now it is a set,
6012 parseCmdLine uses setParseWithComma for linkOptions, in
6013 linkEdit() linkOptions are accessed with new function indexSet()
6014 which returns the i'th item of a set variable. See SDCCset.c, in
6015 linkEdit() when calling buildCmdLine(), added linkOptions as
6016 last argument. Now users can pass arguments to gplink via the
6017 -Wl option, main() uses pic16glue() to glue up pic16 programs

6031 gpasm complaining and test the linkage with gplink, _linkCmd and
6032 _asmCmd changed to be more gplink and gpasm friendly
6033 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6034 produced an error when parsed, peep rule 12 is added to utilize
6035 movff, but it is commented out since the pCode does not support
6036 yet a command with 2 address arguments
6038 2003-05-18 <johan AT balder>
6040 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6063 2003-05-12 Borut Razem <borut.razem AT siol.net>
6065 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
6067 2003-05-11 Borut Razem <borut.razem AT siol.net>
6069 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6070 the path of bin directory, so that PATH is the only env. variable, which has to be set

7075 * src/SDCCicode.c: fixed array add
7077 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7078 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7079 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7081 2003-01-04 <johan AT balder>
7083 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7085 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7086 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7088 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

7098 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7099 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7101 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7103 * in \sdcc\as\mcs51\ changed these files in order to create an
7104 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7105 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7106 following files to include the previous two files: aslink.dsp,
7107 Makefile.aslink, Makefile.bcc, and Makefile.in.
7109 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7110 .adb instead of .cdb
7112 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7114 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7115 value from option --iram-size.
7117 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7119 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7122 2002-09-18 <wiml AT hhhh.org>
7124 * SDCClrange.h: exposed setFromRange() and setToRange()
7125 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7126 packRegsForAccUse() (bug 542397)
7127 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7128 multiple times and emitting the fetch operations more than once
7129 added aopGetUsesAcc() function to allow binary operators to
7130 fetch their operands in the correct order; made genMinus() emit
7131 compact code for X = LITERAL - Y
7133 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7134 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7135 sprintf() in line 1267.
7137 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7138 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7141 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7142 Changes to aslink (All the changes are marked with 'JCF'):
7144 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7147 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7148 area BSEG. Also moves, if possible, the DATA area down into the internal
7149 ram so more space is available.
7151 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7154 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7155 not bytes. Function summary() which creates a memory usage summary
7156 file with extension .mem. Reports of overlaping stack and small stack
7157 size. If the space for the stack is less than 16 bytes aslink trows a
7160 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7161 the 8051. Option 'y' for memory summary output file.
7163 Changes to sdcc (All the changes are marked with 'JCF'):
7165 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7167 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7168 overlaying area for it (uses RegBankUsed[4]).
7170 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7171 bank zero as used by default. By default aslink locates the stack
7172 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7173 the creation of the .mem file. Delegates the allocation of data area
7174 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7175 the begining of the stack area to aslink.
7177 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7178 glue() in SDCCglue.c creates an area for it.
7180 2002-09-03 Borut Razem <borut.razem AT siol.net>
7181 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7182 sdcc/src/pic/glue.c:
7183 introduced atexit() handler for teporay files removal in case of
7184 errors, assertions, ...
7186 2002-08-29 Borut Razem <borut.razem AT siol.net>
7187 * sdcc/support/cpp2/auto-host_vc_in.h:
7188 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7189 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7190 Maybe there is a similar problem with BORLANDC? It should be checked!
7192 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7193 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7194 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7195 was not executed, and the compiler (cl) launched a warning:
7196 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7198 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7199 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7201 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7202 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7204 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7205 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7206 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7207 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7208 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7209 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7210 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7211 - added Release configuration in VS projects
7212 - review of compiler an linker options
7213 - VC .exe files are generated in bin_vc directory, not to interfere
7214 with binaries generated from other projects (cygwin, mingw, bcc ...)
7216 * sdcc/src/yacc.dsp: added
7218 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7219 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7220 and insert the version number definitions from .version
7222 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7224 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7225 added - genarate auto-host.h using auto-host_vc_in.h as template
7228 removed from CVS, generated automatically
7230 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7231 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7233 2002-08-11 Borut Razem <borut.razem AT siol.net>
7234 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7236 2002-08-10 Borut Razem <borut.razem AT siol.net>
7237 * src/SDCCmain.c (main):
7238 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7239 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7240 The consequence was that some temporary files were not removed.
7243 unification of code in functions tempfilename() and tempfile():
7244 function tempnam() is defined in Visual Studio 6.0 and .NET
7246 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7248 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7249 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7250 - removed compiler command line option /WX: Treats all warnings as errors
7251 - update a list of source files, included into the project
7253 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7254 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7255 changed project type to Generic Project so that can be correcly converted to VS.NET project
7257 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7259 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7261 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7263 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7264 added return 0 statements after assert() to make compiler happy
7266 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7267 added newline in the def file to keep MSC compiler satisfied
7269 * sdcc/src/z80/gen.c:
7270 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7271 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7272 - solved MSC error in function aopDump()
7274 * sdcc_vc.h: define PREFIX as "\\sdcc"
7276 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7277 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7280 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7281 - Rewrote the register banking algorithm.
7282 - Added pCode live-range analysis to registers (for now, only non-used and
7283 singly-used registers optimized away)
7285 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7287 * 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.

7316 2002-03-28 Johan Knol <johan AT balder>
7318 * src/SDCCval.c: fixed bug #532436
7320 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7322 Added "char *Processor" field to the port structure.
7325 Added -p option. Allows port dependent processor to be specified.
7328 Initialized the new field char *Processor field to NULL in all ports
7331 Compiler generated registers for interrupt context saving
7332 were not getting allocated.
7334 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7337 Fixed left shift. Will promote the left side of a left shift
7338 if a) left shifting more than size of operand or b) when assigned
7339 to something size > size of left side
7341 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7343 tons of changes. Register allocation has been
7344 rewritten. Added customization for the various PICs. Flow
7345 analysis is restructured. ...
7351 Added. device.c is a PIC port hack to accomodate variations
7354 2002-03-13 Michael Hope <michaelh AT vroom>
7356 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

7451 * sdcc/src/SDCCloop.c:
7452 Previous fix was not good. basic blocks that have "break" or "return" are
7453 not really partof a loop , but live ranges used in these blocks should
7454 be live thru the entire loop, so set partOfLoop but don't add them to
