1383 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1385 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1386 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1388 One basic decision: e.g. src/clean.mk includes further files. In order
1389 to make this work there are two solutions:
1390 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1391 run configure on them. This way they can use
1392 'include $(srcdir)/port-clean.mk'
1393 - always include clean.mk by the Makefile at the same level. To avoid
1394 that `make clean` tries to include and build Makefile.dep the
1395 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1396 implemented, because now even `make uninstall` doesn't create
1397 Makefile.in. clean.mk could be eliminated by pasting it in
1400 * debugger/mcs51/Makefile.in: build own objects from library sources
1401 (SLIB, SDCC) in current directory
1403 * configure, configure.in: renamed --disable-device-lib-build in
1404 --disable-device-lib; added --enable-doc, the required tools are
1405 searched by configure; added result message; the toolchain for the
1406 belonging ports are now only built, if the port is enabled.
1408 * support/regression/*: all output is written in directory gen, because
1409 the fwk and ports directories don't livet in the build tree using vpath
1411 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1412 --disable-device-lib, added --enable-doc, added section VPATH
1414 * sim/ucsim/configure.in,
1415 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1416 z80 are enabled by default
1418 2006-04-24 Raphael Neider <rneider AT web.de>
1420 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1421 to config word, "pic14_"-prefixed some extern functions

1733 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1734 call to allocReg, not by manually allocating a new one,
1735 (pic16_assignRegisters): now before going through the register
1736 allocating functions mark all registers as free. This eliminates some
1737 side effects resulting from peephole parser done earlier in the backbone

1785 * device/include/mcs51/c8051f410.h: new SiLabs mcu
1786 * src/ds390/peeph.def: disabled 186.d and 227.a as fix for #1434401
1787 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
1789 2006-03-06 Borut Razem <borut.razem AT siol.net>
1791 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1792 made the linker quiet
1794 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1796 * src/pic16/gen.c (genPcall): fixed bug #1443644
1797 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1798 which dumps before the function entry point a data byte which represents
1799 the number of the local variables used by the specified function, added
1800 'xinst' for initial support for Extended Instruction Support,
1801 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1802 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1803 port->fun_prefix anymore (may change later),
1804 (genFunction, genEndFunction): do not store/restore local registers for
1805 _main (this should take care the --main-return command line option in
1807 (genOr): removed some legacy pic-port instructions,
1808 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1809 performing operations with SFR's causes data to be written more than
1810 once to each SFR. Perhaps SFRs should be handled in special cases...
1811 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1813 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1814 into account for stack starting position,
1815 (struct OPTIONS pic16_optionsTable): added command line argument
1816 --extended or -y for Extended Instruction Support,
1817 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1818 (deassignLRs): *** perhaps the most important change, old 'for' code
1819 (commented out for reference), didn't account for some registers which
1820 were left marked 'not free' after a pointer operation. The change
1821 reduces register usage a lot in some cases

4096 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4097 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4098 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4099 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4100 always available in leading double underscore form. The C99 support is

4181 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4183 * device/lib/printf_large.c: removed inline assembly for portability and
4184 readability. Use printf_fast if speed or size are more important.
4185 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4186 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4188 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4190 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4191 prevent compiler warning
4193 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4195 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4196 moved to level 0 and declared as static. Also they are explicit
4197 placed in access bank. This was necessery because some times they
4198 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4199 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4200 optimizations. Currently only compare to unsigned char is implemented,
4201 * src/pic16/gen.c: added fReturnIdx array,
4202 * (struct resolvedIfx) is moved to gen.h and made public,
4203 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4204 * (aopForSym): added an optimization to directly store in stack of
4205 the operand of a SEND iCode,
4206 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4207 but as registers instead (AOP_REG) using the fReturnIdx array,
4208 * (pic16_freeAsmop): remove the freed register from the
4209 _G.sregsAlloc field,
4210 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4211 a compare of 'WREG',
4212 * (pic16_popGetTempRegCond): changed function prototype, now
4213 function takes also a bitVector argument v which holds the current
4214 set of registers that are allocated for stack access by aopForSym,
4215 registers allocated in aopForSym for accessing stack symbols are not
4216 any more part of the functions usedRegs field,
4217 * (genCall): some times aopOp is called for a stack variable to be
4218 send, aopForSym might perform the push, if this is true make sure
4219 that genCall doesn't push the variable twice by testing _G.resDirect,
4220 * (genFunction): changed testing for unspecified interrupt number
4221 from 256 to INTNO_UNSPEC,
4222 * modified selection scheme of frame pointer generation. Previously
4223 if function did use local registers a frame pointer was generated,
4224 now a frame pointer is generated only if function has arguments
4225 (that need PLUSW2 register access), or has stack arguments, or the
4226 compiler is not instructed to omit the frame pointer,
4227 * (genEndFunction): before restoring local registers that were saved
4228 in the function preamble, also restore the registers that *might*
4229 have been allocated for stack access,
4230 * (genRet): removed some old comments,
4231 * (genCmp, the active (RN's) version): added a call to the
4232 pic16_genCmp_special function to perform the compare with a more
4233 robust and optimized way,
4234 * (genInline): a feature has been added in inline code generation,
4235 which allows a wildcard variable substitution when writing inline
4236 assembly. Code is incomplete and experimental therefore undocumented,
4237 * (genCast): changed order of aopOp for result and right to allow
4238 aopForSym to directly load the result if possible,
4239 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4240 perform an optimized compare on some selected special occasions,
4241 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4242 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4243 generate an IVT any more,
4244 * src/pic16/main.c (pic16_optionsTable): added command line option
4246 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4247 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4249 * src/pic16/NOTES: Raphael Neider added in list of active developers
4250 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4251 jumptable_end to prevent bug #,
4252 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4253 inCond and outCond fields,
4254 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4255 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4256 turn off register spilling,
4257 * (packRegsForOneUse): synced with other ports' versions although it
4258 is not used currently,
4259 * (pic16_packRegisters): added an optimization while reading
4260 structure bitfields, some registers may be saved (malloc code is
4261 decreased by 80 bytes)
4263 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4265 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4266 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4267 this can be optimized more?
4269 2005-03-10 Raphael Neider <rneider AT web.de>
4271 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4272 genNearPointerGet): (hopefully) fixed access to bitfields via
4273 pointers (p->bitN = x; and x = p->bitN; failed)
4275 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
4277 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

4907 Adding support for replacing ljmps with sjmps in jumptables
4908 generated for switch statements. For now you need to set the
4909 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4910 Now 4 algorithms for mcs51 jumptable generation are used:
4911 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4912 addresses loaded pc-relative for up to 112 cases and stack-pushing
4913 target addresses loaded with offset from dptr for up to 256 cases.

4940 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4941 to call when a stack overflow occurs,
4942 * (malloc.h): added CVS Id tag,
4943 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4945 * added libc directory. The current version of LibC contains string
4946 functions, ctype functions and macros and some functions of the
4947 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4948 be extensively tested in the future. Standard disclaimer here.
4949 Library is not automatically build yet. But one can build it by
4950 invoking 'make' inside the libc directory.
4951 * added ADC library under libio. Preliminary version yet.

4957 temporary registers, its a buggy feature and will be removed,
4958 * (pic16_popGet): set register instance field in AOP_CRY,
4959 * (pic16_outBitC): fixed for results in size greater than 1,
4960 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4961 * (pic16_storeForReturn): optimized return of 0,
4962 * (genCmp): experimental code for new genCmp which uses PIC18's
4963 special compare&skip instructions. Initial tests fail some times
4964 with variables grater than 1 byte in size, so new code is disabled,
4965 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4967 * (genCast): began a fix to optimize the casting of a bit to another
4968 bit, now assigning a bitfield to another bitfield will fail, sorry,
4969 * src/pic16/main.c: disabled the use of lr-support feature,
4970 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
4971 * added some function prototypes, added function _debugf prototype,

4973 bits with offset (case PO_GPR_BIT),
4974 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4976 * (isBankInstruction): modified to return 0 for no banking instruction,
4977 and 1 for banking instruction,
4978 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4979 caused stop processing pCodes after a inline assembly block,
4980 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4981 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4982 registers when it shouldn't,
4983 * src/pic16/ralloc.c (allocReg): add preliminary support for
4984 supporting a limited set of temporary registers,
4986 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4988 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4989 genDataPointerSet): ensure assignments always copy in MSB to LSB
4991 (loadRegFromAop): recognize CLRH optimization,
4992 (genFunction): optimize RECEIVE iCodes in reentrant functions
4994 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4996 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
4997 --out-fmt-s19 turning into --out-fmt-elf if s19 was already

7991 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7993 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7994 loaded with the linker search paths (-L arguments) and the libraries
7995 to be linked with the current source (-l arguments). Changes
7996 currently will affect only the pic16 port.
7997 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7998 include path the port specific paths and port specific libraries,
7999 * gplink command now contains the $3 argument,
8000 * src/pic16/device.h,
8001 * src/pic16/device.c,: structure PIC_device is made public and

8017 Documenting changes from previous commits.
8018 * configure.in (version 1.56),
8019 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8020 when generating output files to configure the pic16 library,
8021 but now I've commented it out, since gputils aren't installed in the
8022 SF compile farm, so library won't compile
8024 * device/lib/Makefile.in (version 1.56): initially I've added in
8025 target 'all' the prerequestive 'model-pic16' so it compiled the
8026 pic16 library, but now I've commented it out for the same reasons
8028 * added targets 'model-pic16' and 'objects-pic16' to compile the
8030 * added target 'port-specific-objects-pic16' to handle the
8031 generated libraries and copy them into the build/ directory
8032 * added target 'clean-intermediate-pic16' to clean intermediate
8033 files into pic16 directory
8034 * in target 'installdirs' added line to create directory pic16 in

8038 added lines to copy all header files to installation path,
8039 * in target 'installdirs' added line create directory for pic16
8040 headers in the installation path

8333 genFunction,genEndFunction: setup stack frame for the
8335 genAddrOf: will be changed according to bug 863624
8337 * added files genutils.c and genutils.h which contain gen*
8338 debugged and optimised functions extracted from gen.c
8340 * glue.c: added variable 'externs' which holds extern symbols,
8341 pic16emitRegularMap: is modified to properly handle relocatable
8342 symbols under the new scheme,
8343 pic16createInterruptVect: is modified
8344 pic16printPublics: is modified to emit 'global' assembler directives,
8345 added pic16_printExterns to print extern symbols,
8346 pic16glue: initializes stack/frame pointer in the beginning of
8347 the assembly output. Temporary hack, will be corrected later,
8348 because gplink yet does not support stack and SDCC does not
8349 yet support a type of crt0.o object to create the final binary.
8351 * Removed many lines that contain 8051 legacy code.
8352 * The code is finally placed under a 'code' directive.
8353 * Added port specific options.
8355 * _process_pragma: simplified since now we do not need *special*
8356 include file to define SFR registers. But a separate header
8357 will be needed. This will be developed later.
8358 * _pic16_parseOptions: added, parses port specific options:
8359 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8360 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8361 --preplace-udata-with=
8363 * _pic16_setDefaultOptions: modified to initialize section names,
8364 but hack is temporarly out of order since it needs improvement.
8365 * _pic16_genAssemblerPreamble: configuration words are emitted by
8366 their address instead of their name. This part is incomplete and
8367 supports only the 18Fxx2 devices. Other devices will emit an error
8368 during assembly since they do not contain the same set of config
8370 * _pic16_genIVT: is modified,
8372 * pcode.c: added definitions for some hardware registers that are needed
8374 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8375 All PCI entries are updated. Now LFSR is supported.
8376 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8377 * added pic16_newpCodeOpLit2 to support instructions with
8378 two literal arguments
8379 * pic16_pCode2str: corrected code that emits assembler instructions
8380 with two literal operands and those that have an access bit modifier
8381 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8382 this fixes a bug which caused some labels to be lost, when an
8383 assembler directive was added, i.e. banksel,
8384 * pic16_FixRegisterBanking: improved logic that causes the insertion
8386 * InlineFunction: functions that are called once, are not any more
8387 inlined. This can be a port option in the future,
8389 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8391 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8392 hold the corresponding uninitialized symbols,
8393 * pic16_allocProcessorRegister: registers have explicit marked the
8395 * pic16_allocInternalRegister: registers are explicit marked as
8397 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8398 processing list, so bit registers were lost,
8401 * ralloc.h: added field 'accessBank' and original symbol operand
8402 in register definition,
8403 * removed the field isMapped from register definition,
8405 ** Several functions have been removed from various sources:
8406 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8407 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8408 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8409 pic16_assignRelocatableRegisters
8411 ** others have been introduced:
8412 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8413 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8415 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8417 * support/scripts/inc2h.pl: changed definition of BIT_AT
8418 to emit 'sbit at' instead of 'bit at'. This was a request.
8420 PIC16 port related preliminary changes:
8421 * gen.c: prefixed function popRegFromString with
8422 pic16_ and all references to it corrected
8423 * pcode.c: all pic16_pc_* hardware registers prefixed
8424 with underscore (_),
8425 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8426 * ralloc.c: newReg(): when register is REG_SFR then
8427 set address to rIdx,
8428 pic16_allocProcessorRegister(): marks register wasUsed=0
8429 pic16_writeUsedRegs(): added a call to assign processor
8430 registers via pic16_assignFixedRegisters
8432 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8434 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8435 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8436 variables in unused register banks. Also the SSEG is placed
8437 wherever there is enough space for it, and IDATA can be anywhere
8438 in internal RAM. For now compile using -Wl-Y[stack_size].
8439 The mem file is different for this option as well, since it
8440 makes no sense of talking about DSEG lenght.
8442 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8444 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8445 in certain cases, e.g. when ROM assignment, patch provided
8446 from Albert den Haan.

8687 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8689 * src/SDCCast.c (decorateType): disabled a transformation I added in
8690 revision 1.188 (access to fields of a structure at an absolute address);
8691 it breaks with bitfields, extern declarations, and gcse analysis.
8692 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8693 could be assigned through a pointer, so don't complain.
8694 * src/SDCCast.c (astErrors),
8696 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

9450 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9451 fetching of the pointer
9452 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9453 copied from genNearPointerSet()
9454 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9455 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

9469 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9471 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9472 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9473 type for bits was changed. It resulted in bit variables becoming
9474 global, which is not permitted in PIC 14 assembly output.
9476 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9478 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9491 A few small changes that speed up the peephole optimizer.
9495 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9497 Try to make the peephole optimizer smarter by maintaining
9498 an association between the assembly source code and the
9499 iCodes that originated them. Put this information to use
9500 with a new peephole rule condition "notVolatile" so that
9501 the rules can be aggressive yet still safe.
9506 * src/mcs51/peeph.def
9508 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9512 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9513 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9514 if the left or right operand symbols have the accuse flag set.
9516 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9518 Changed the type of the result of the ! (NOT) operator to char;
9519 previously it returned the same type as the source. This allows
9520 us to eliminate all the genFloatNot functions (all of its target
9521 implementations were very buggy) since !float can use the same
9524 * src/SDCCicode.c (ast2iCode): ! returns char

9533 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9534 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9535 during interrupts. Ensure WSAVE is located at a shared bank address.
9536 2. Fixed page selection in some places
9537 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9538 the registers name strings.
9539 4. Fixed "signed / unsigned compare" compiler warnings.
9540 5. The PIC port manages its own allocation of the general purpose
9541 registers, but makes no attempt to reuse them. As a result when
9542 compiling it soon runs out of general purpose registers. Some
9543 additional code was added to the files pcode.c and device.c to walk
9544 through the function call tree and rename the registers so that they
9554 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9555 genPlus() & genMinus() when the result is the same as left or right

9561 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9563 Made bitfield a distinct type from bit so that bitfields
9564 convert as per ANSI C and bits retain their traditional
9565 boolean style behaviour. Implemented bitfield support in
9573 * src/ds390/gen.c: bit v bitfield split
9574 * src/z80/gen.c: New support for bitfields
9575 * support/regression/tests/bitfields.c: reenabled z80,
9578 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9580 Rules 246.x, 247.x relate to bitfields, the others speed up
9581 access to xdata mapped I/O devices.
9583 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9585 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9587 Cleaned up genPackBits and genUnpackBits and added two helper
9588 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9589 for literal assignments in genPackBits (thanks to Frieder for
9595 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9597 Fixed bug #748310 (pointer to function type mishandled when the
9598 function name is omitted). Also fixed a SIGSEGV when a function
9599 attribute (reentrant, etc) is used on a non-function or on a
9600 function but misplaced before the parameter list.
9602 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9604 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9605 * support/Util/SDCCerr.h,
9606 * support/Util/SDCCerr.c: Added func attr misuse error msg

9627 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9629 Made the constant following the "interrupt" keyword optional. If
9630 omitted, the function will not automatically be given an entry
9631 in the interrupt vector table (similar to #pragma NOIV, but
9632 less syntacticly kludgy). The interrupt number is also now
9633 range checked. Also fixed a bug in the high order bit example

9647 * src/SDCCicode.c (operandOperation): rewritten some ops
9648 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9649 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9651 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9652 be re-activated by defining REDUCE_LITERALS)
9653 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9654 unsigned, but are signed by default
9655 * src/SDCCval.c (constVal): rearranged
9656 * src/SDCCval.c (valMod): preliminary fix
9657 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9699 constants are unsigned; added recognition of "u" flag for unsigned
9700 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9701 * src/SDCCval.c (valDiv, valMod): fixed signdness
9702 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9703 signedness of modulo, left and right shift

10164 messages from optionsTable when a port is not configured, added
10165 support for the PIc16 port in the ports table, when executing
10166 the compiler with no port specified on command line, a default
10167 port is selected with the new macro DEFAULT_PORT which is
10168 defined in port.h, in setDefaultOptions() linkOptions is removed
10169 from initialization assignment, since now it is a set,
10170 parseCmdLine uses setParseWithComma for linkOptions, in
10171 linkEdit() linkOptions are accessed with new function indexSet()
10172 which returns the i'th item of a set variable. See SDCCset.c, in
10173 linkEdit() when calling buildCmdLine(), added linkOptions as
10174 last argument. Now users can pass arguments to gplink via the
10175 -Wl option, main() uses pic16glue() to glue up pic16 programs

10189 gpasm complaining and test the linkage with gplink, _linkCmd and
10190 _asmCmd changed to be more gplink and gpasm friendly
10191 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10192 produced an error when parsed, peep rule 12 is added to utilize
10193 movff, but it is commented out since the pCode does not support
10194 yet a command with 2 address arguments
10196 2003-05-18 <johan AT balder>
10198 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11222 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
11223 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings
11224 * src/pic/pcode.c: outcommented unused variable to remove warnings

11231 2003-01-06 <johan AT balder>
11233 * src/SDCCicode.c: fixed array add
11235 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
11236 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
11237 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
11239 2003-01-04 <johan AT balder>
11241 * src/SDCCval.c (getNelements): fixed the initialized array of structures
11243 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11244 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
11246 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11247 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
11248 * support/regression/tests/bug-524697.c: fit mem usage into 8032
11250 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11251 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
11253 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11254 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11256 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11257 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11259 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11261 * in /sdcc/as/mcs51/ changed these files in order to create an
11262 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11263 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11264 following files to include the previous two files: aslink.dsp,
11265 Makefile.aslink, Makefile.bcc, and Makefile.in.
11267 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11268 .adb instead of .cdb
11270 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11272 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11273 value from option --iram-size.
11275 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11277 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11280 2002-09-18 <wiml AT hhhh.org>
11282 * SDCClrange.h: exposed setFromRange() and setToRange()
11283 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11284 packRegsForAccUse() (bug 542397)
11285 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11286 multiple times and emitting the fetch operations more than once
11287 added aopGetUsesAcc() function to allow binary operators to
11288 fetch their operands in the correct order; made genMinus() emit
11289 compact code for X = LITERAL - Y
11291 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11292 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11293 sprintf() in line 1267.
11295 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11296 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11299 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11300 Changes to aslink (All the changes are marked with 'JCF'):
11302 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11305 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11306 area BSEG. Also moves, if possible, the DATA area down into the internal
11307 ram so more space is available.
11309 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11312 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11313 not bytes. Function summary() which creates a memory usage summary
11314 file with extension .mem. Reports of overlaping stack and small stack
11315 size. If the space for the stack is less than 16 bytes aslink trows a
11318 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11319 the 8051. Option 'y' for memory summary output file.
11321 Changes to sdcc (All the changes are marked with 'JCF'):
11323 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11325 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11326 overlaying area for it (uses RegBankUsed[4]).
11328 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11329 bank zero as used by default. By default aslink locates the stack
11330 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11331 the creation of the .mem file. Delegates the allocation of data area
11332 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11333 the begining of the stack area to aslink.
11335 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11336 glue() in SDCCglue.c creates an area for it.
11338 2002-09-03 Borut Razem <borut.razem AT siol.net>
11339 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11340 sdcc/src/pic/glue.c:
11341 introduced atexit() handler for teporay files removal in case of
11342 errors, assertions, ...
11344 2002-08-29 Borut Razem <borut.razem AT siol.net>
11345 * sdcc/support/cpp2/auto-host_vc_in.h:
11346 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11347 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11348 Maybe there is a similar problem with BORLANDC? It should be checked!
11350 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11351 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11352 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11353 was not executed, and the compiler (cl) launched a warning:
11354 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11356 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11357 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11359 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11360 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11362 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11363 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11364 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11365 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11366 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11367 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11368 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11369 - added Release configuration in VS projects
11370 - review of compiler an linker options
11371 - VC .exe files are generated in bin_vc directory, not to interfere
11372 with binaries generated from other projects (cygwin, mingw, bcc ...)
11374 * sdcc/src/yacc.dsp: added
11376 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11377 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11378 and insert the version number definitions from .version
11380 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11382 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11383 added - genarate auto-host.h using auto-host_vc_in.h as template
11386 removed from CVS, generated automatically
11388 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11389 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11391 2002-08-11 Borut Razem <borut.razem AT siol.net>
11392 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11394 2002-08-10 Borut Razem <borut.razem AT siol.net>
11395 * src/SDCCmain.c (main):
11396 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11397 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11398 The consequence was that some temporary files were not removed.
11401 unification of code in functions tempfilename() and tempfile():
11402 function tempnam() is defined in Visual Studio 6.0 and .NET
11404 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11406 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11407 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11408 - removed compiler command line option /WX: Treats all warnings as errors
11409 - update a list of source files, included into the project
11411 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11412 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11413 changed project type to Generic Project so that can be correcly converted to VS.NET project
11415 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11417 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11419 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11421 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11422 added return 0 statements after assert() to make compiler happy
11424 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11425 added newline in the def file to keep MSC compiler satisfied
11427 * sdcc/src/z80/gen.c:
11428 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11429 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11430 - solved MSC error in function aopDump()
11432 * sdcc_vc.h: define PREFIX as "\\sdcc"
11434 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11435 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11438 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11439 - Rewrote the register banking algorithm.
11440 - Added pCode live-range analysis to registers (for now, only non-used and
11441 singly-used registers optimized away)
11443 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11445 * 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.

11468 * src/z80/main.c: Added force callee saves for jaune.
11470 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11472 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11474 2002-03-28 Johan Knol <johan AT balder>
11476 * src/SDCCval.c: fixed bug #532436
11478 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11480 Added "char *Processor" field to the port structure.
11483 Added -p option. Allows port dependent processor to be specified.
11486 Initialized the new field char *Processor field to NULL in all ports
11489 Compiler generated registers for interrupt context saving
11490 were not getting allocated.
11492 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11495 Fixed left shift. Will promote the left side of a left shift
11496 if a) left shifting more than size of operand or b) when assigned
11497 to something size > size of left side
11499 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11501 tons of changes. Register allocation has been

11503 analysis is restructured. ...
11505 * src/pic/device.h:
11508 * src/pic/device.c:
11509 Added. device.c is a PIC port hack to accomodate variations
11512 2002-03-13 Michael Hope <michaelh AT vroom>
11514 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11516 2002-03-04 johanknol <johanknol AT manik>
11518 * /src/SDCCval.c: fixed
11520 const unsigned char arr[][2] = { { 0, 1 } };

11607 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11609 * sdcc/src/SDCCloop.c:
11610 Previous fix was not good. basic blocks that have "break" or "return" are
11611 not really partof a loop , but live ranges used in these blocks should
11612 be live thru the entire loop, so set partOfLoop but don't add them to
11615 2002-02-21 <johan AT FRIJA>
11617 * src/SDCCcse.c: fixed bug #514308
11619 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
11622 Fixed BUG #519583. If a conditional block ended in a return/break
11623 statement inside a loop, it was not being considered part of the loop.
11625 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
11627 2002-02-10 Karl Bongers <karl AT turbobit.com>

11641 Took out debug printfs in ucsim "next" command.
11643 * sim/ucsim/xa.src:
11644 Karl and Johan start ucsim XA support. Most dissassembly working,
11645 about 75% emulation done(plenty of work remaining).
11647 * sim/ucsim/z80.src:
11648 Add Z80 support to ucsim, add test-ucz80 regression test,
11649 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
11650 Notice z80 compiler fails on examples/test3.c/crc code.
11652 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
11654 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:

11664 3) added __builtin_swapw swap bytes of a short
11666 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
11667 1) handle multiple send & receives from register bank1
11668 2) ralloc can now allocate DPTR1 to some liveRanges
11670 * src/SDCCsymt.c, src/SDCCsymt.h:
11671 changes to handle multiple sends & receives
