503 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
505 Enabled VPATH feature: changed nearly all Makefiles (149 files).
506 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
508 One basic decision: e.g. src/clean.mk includes further files. In order
509 to make this work there are two solutions:
510 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
511 run configure on them. This way they can use
512 'include $(srcdir)/port-clean.mk'
513 - always include clean.mk by the Makefile at the same level. To avoid
514 that `make clean` tries to include and build Makefile.dep the
515 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
516 implemented, because now even `make uninstall` doesn't create
517 Makefile.in. clean.mk could be eliminated by pasting it in
520 * debugger/mcs51/Makefile.in: build own objects from library sources
521 (SLIB, SDCC) in current directory
523 * configure, configure.in: renamed --disable-device-lib-build in
524 --disable-device-lib; added --enable-doc, the required tools are
525 searched by configure; added result message; the toolchain for the
526 belonging ports are now only built, if the port is enabled.
528 * support/regression/*: all output is written in directory gen, because
529 the fwk and ports directories don't livet in the build tree using vpath
531 * doc/sdccman.lyx: renamed --disable-device-lib-build to
532 --disable-device-lib, added --enable-doc, added section VPATH
534 * sim/ucsim/configure.in,
535 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
536 z80 are enabled by default
538 2006-04-24 Raphael Neider <rneider AT web.de>
540 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
541 to config word, "pic14_"-prefixed some extern functions
542 (pic14_emitConfigWord): emit __config directive(s) if assignment to
543 config word has been found
544 * src/pic/device.h: added prototypes

854 call to allocReg, not by manually allocating a new one,
855 (pic16_assignRegisters): now before going through the register
856 allocating functions mark all registers as free. This eliminates some
857 side effects resulting from peephole parser done earlier in the backbone

917 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
918 which dumps before the function entry point a data byte which represents
919 the number of the local variables used by the specified function, added
920 'xinst' for initial support for Extended Instruction Support,
921 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
922 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
923 port->fun_prefix anymore (may change later),
924 (genFunction, genEndFunction): do not store/restore local registers for
925 _main (this should take care the --main-return command line option in
927 (genOr): removed some legacy pic-port instructions,
928 * src/pic16/genarith.c (genAddLit): re-enabled old code because
929 performing operations with SFR's causes data to be written more than
930 once to each SFR. Perhaps SFRs should be handled in special cases...
931 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
933 * src/pic16/main.c (_process_pragma): stack bound checking did not take
934 into account for stack starting position,
935 (struct OPTIONS pic16_optionsTable): added command line argument
936 --extended or -y for Extended Instruction Support,
937 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
938 (deassignLRs): *** perhaps the most important change, old 'for' code
939 (commented out for reference), didn't account for some registers which
940 were left marked 'not free' after a pointer operation. The change
941 reduces register usage a lot in some cases

3216 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3217 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3218 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3219 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3220 always available in leading double underscore form. The C99 support is
3221 mostly missing, but it's a start.
3222 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3223 reserved identifier "__data".

3301 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3303 * device/lib/printf_large.c: removed inline assembly for portability and
3304 readability. Use printf_fast if speed or size are more important.
3305 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3306 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3308 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3310 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3311 prevent compiler warning
3313 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3315 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3316 moved to level 0 and declared as static. Also they are explicit
3317 placed in access bank. This was necessery because some times they
3318 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3319 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3320 optimizations. Currently only compare to unsigned char is implemented,
3321 * src/pic16/gen.c: added fReturnIdx array,
3322 * (struct resolvedIfx) is moved to gen.h and made public,
3323 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3324 * (aopForSym): added an optimization to directly store in stack of
3325 the operand of a SEND iCode,
3326 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3327 but as registers instead (AOP_REG) using the fReturnIdx array,
3328 * (pic16_freeAsmop): remove the freed register from the
3329 _G.sregsAlloc field,
3330 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3331 a compare of 'WREG',
3332 * (pic16_popGetTempRegCond): changed function prototype, now
3333 function takes also a bitVector argument v which holds the current
3334 set of registers that are allocated for stack access by aopForSym,
3335 registers allocated in aopForSym for accessing stack symbols are not
3336 any more part of the functions usedRegs field,
3337 * (genCall): some times aopOp is called for a stack variable to be
3338 send, aopForSym might perform the push, if this is true make sure
3339 that genCall doesn't push the variable twice by testing _G.resDirect,
3340 * (genFunction): changed testing for unspecified interrupt number
3341 from 256 to INTNO_UNSPEC,
3342 * modified selection scheme of frame pointer generation. Previously
3343 if function did use local registers a frame pointer was generated,
3344 now a frame pointer is generated only if function has arguments
3345 (that need PLUSW2 register access), or has stack arguments, or the
3346 compiler is not instructed to omit the frame pointer,
3347 * (genEndFunction): before restoring local registers that were saved
3348 in the function preamble, also restore the registers that *might*
3349 have been allocated for stack access,
3350 * (genRet): removed some old comments,
3351 * (genCmp, the active (RN's) version): added a call to the
3352 pic16_genCmp_special function to perform the compare with a more
3353 robust and optimized way,
3354 * (genInline): a feature has been added in inline code generation,
3355 which allows a wildcard variable substitution when writing inline
3356 assembly. Code is incomplete and experimental therefore undocumented,
3357 * (genCast): changed order of aopOp for result and right to allow
3358 aopForSym to directly load the result if possible,
3359 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3360 perform an optimized compare on some selected special occasions,
3361 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3362 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3363 generate an IVT any more,
3364 * src/pic16/main.c (pic16_optionsTable): added command line option
3366 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3367 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3369 * src/pic16/NOTES: Raphael Neider added in list of active developers
3370 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3371 jumptable_end to prevent bug #,
3372 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3373 inCond and outCond fields,
3374 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3375 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3376 turn off register spilling,
3377 * (packRegsForOneUse): synced with other ports' versions although it
3378 is not used currently,
3379 * (pic16_packRegisters): added an optimization while reading
3380 structure bitfields, some registers may be saved (malloc code is
3381 decreased by 80 bytes)
3383 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3385 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3386 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3387 this can be optimized more?
3389 2005-03-10 Raphael Neider <rneider AT web.de>
3391 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3392 genNearPointerGet): (hopefully) fixed access to bitfields via
3393 pointers (p->bitN = x; and x = p->bitN; failed)
3395 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3438 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
3439 to keep the correct label reference count when adding/removing references
3440 to labels. A peephole file using this is appended to patch #1144962.
3442 2005-02-14 Raphael Neider <rneider AT web.de>

4027 Adding support for replacing ljmps with sjmps in jumptables
4028 generated for switch statements. For now you need to set the
4029 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4030 Now 4 algorithms for mcs51 jumptable generation are used:
4031 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4032 addresses loaded pc-relative for up to 112 cases and stack-pushing
4033 target addresses loaded with offset from dptr for up to 256 cases.

4063 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4065 * added libc directory. The current version of LibC contains string
4066 functions, ctype functions and macros and some functions of the
4067 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4068 be extensively tested in the future. Standard disclaimer here.
4069 Library is not automatically build yet. But one can build it by
4070 invoking 'make' inside the libc directory.

4081 * (pic16_storeForReturn): optimized return of 0,
4082 * (genCmp): experimental code for new genCmp which uses PIC18's
4083 special compare&skip instructions. Initial tests fail some times
4084 with variables grater than 1 byte in size, so new code is disabled,
4085 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4087 * (genCast): began a fix to optimize the casting of a bit to another
4088 bit, now assigning a bitfield to another bitfield will fail, sorry,
4089 * src/pic16/main.c: disabled the use of lr-support feature,
4090 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4097 and 1 for banking instruction,
4098 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4099 caused stop processing pCodes after a inline assembly block,
4100 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4101 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4102 registers when it shouldn't,
4103 * src/pic16/ralloc.c (allocReg): add preliminary support for
4104 supporting a limited set of temporary registers,
4106 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4108 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4109 genDataPointerSet): ensure assignments always copy in MSB to LSB
4111 (loadRegFromAop): recognize CLRH optimization,
4112 (genFunction): optimize RECEIVE iCodes in reentrant functions
4114 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4116 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

7025 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
7027 * src/SDCCast.c: added an additional type flow in decorateType() of
7028 opposite direction, see feature request #860006; it's enabled at runtime
7029 by setting the environment variable SDCC_NEWTYPEFLOW
7030 * src/SDCCast.h: changed prototype of decorateType()
7031 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
7032 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from

7066 code / RAM are in the same page / bank. This means the linker can
7067 safely allocate code/RAM of separate ASM files to different pages/banks.
7068 * doc/sdccman.lyx: added Slade's tips

7111 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7113 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7114 loaded with the linker search paths (-L arguments) and the libraries
7115 to be linked with the current source (-l arguments). Changes
7116 currently will affect only the pic16 port.
7117 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7118 include path the port specific paths and port specific libraries,
7119 * gplink command now contains the $3 argument,
7120 * src/pic16/device.h,
7121 * src/pic16/device.c,: structure PIC_device is made public and
7122 renamed to PIC16_device, the same for variable Pics which is renamed

7137 Documenting changes from previous commits.
7138 * configure.in (version 1.56),
7139 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7140 when generating output files to configure the pic16 library,
7141 but now I've commented it out, since gputils aren't installed in the
7142 SF compile farm, so library won't compile
7144 * device/lib/Makefile.in (version 1.56): initially I've added in
7145 target 'all' the prerequestive 'model-pic16' so it compiled the
7146 pic16 library, but now I've commented it out for the same reasons
7148 * added targets 'model-pic16' and 'objects-pic16' to compile the
7150 * added target 'port-specific-objects-pic16' to handle the
7151 generated libraries and copy them into the build/ directory
7152 * added target 'clean-intermediate-pic16' to clean intermediate
7153 files into pic16 directory
7154 * in target 'installdirs' added line to create directory pic16 in
7155 the installation path

7158 added lines to copy all header files to installation path,
7159 * in target 'installdirs' added line create directory for pic16
7160 headers in the installation path

7176 option so that it actually works. Made it specific to the z80, since
7177 the gbz80 doesn't have these kinds of I/O ports.
7179 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7181 * device/include/z180.h,

7205 via literal number. The symbol is placed in the corresponding
7206 position of the data ram
7207 * (pic16_dump_section): relocatable and absolute uninitialized
7208 data are now emitted in sorted order to reduce section naming,
7209 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7210 weren't marked as being in the access bank,
7212 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7214 Added portion of GNU PIC Library under the directory
7215 device/include/pic16 and device/lib/pic16. These files
7216 contain the declarations of SFRs for the PIC18Fxx2 devices.
7217 The directory is initialized via configure from toplevel.

7449 added variable stackPos,
7451 * gen.c: genCall, assignResultValue: added support for
7452 pushing/retrieving function parameters to/from stack,
7453 genFunction,genEndFunction: setup stack frame for the
7455 genAddrOf: will be changed according to bug 863624

7460 * glue.c: added variable 'externs' which holds extern symbols,
7461 pic16emitRegularMap: is modified to properly handle relocatable
7462 symbols under the new scheme,

7468 because gplink yet does not support stack and SDCC does not
7469 yet support a type of crt0.o object to create the final binary.
7471 * Removed many lines that contain 8051 legacy code.
7472 * The code is finally placed under a 'code' directive.
7473 * Added port specific options.
7475 * _process_pragma: simplified since now we do not need *special*
7476 include file to define SFR registers. But a separate header
7477 will be needed. This will be developed later.
7478 * _pic16_parseOptions: added, parses port specific options:
7479 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7480 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7481 --preplace-udata-with=
7483 * _pic16_setDefaultOptions: modified to initialize section names,
7484 but hack is temporarly out of order since it needs improvement.
7485 * _pic16_genAssemblerPreamble: configuration words are emitted by
7486 their address instead of their name. This part is incomplete and
7487 supports only the 18Fxx2 devices. Other devices will emit an error
7488 during assembly since they do not contain the same set of config
7490 * _pic16_genIVT: is modified,
7492 * pcode.c: added definitions for some hardware registers that are needed
7494 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7495 All PCI entries are updated. Now LFSR is supported.
7496 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7497 * added pic16_newpCodeOpLit2 to support instructions with
7498 two literal arguments
7499 * pic16_pCode2str: corrected code that emits assembler instructions
7500 with two literal operands and those that have an access bit modifier
7501 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7502 this fixes a bug which caused some labels to be lost, when an
7503 assembler directive was added, i.e. banksel,
7504 * pic16_FixRegisterBanking: improved logic that causes the insertion
7506 * InlineFunction: functions that are called once, are not any more
7507 inlined. This can be a port option in the future,
7509 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7511 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7512 hold the corresponding uninitialized symbols,
7513 * pic16_allocProcessorRegister: registers have explicit marked the
7515 * pic16_allocInternalRegister: registers are explicit marked as
7517 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7518 processing list, so bit registers were lost,
7521 * ralloc.h: added field 'accessBank' and original symbol operand
7522 in register definition,
7523 * removed the field isMapped from register definition,
7525 ** Several functions have been removed from various sources:
7526 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7527 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7528 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7529 pic16_assignRelocatableRegisters
7531 ** others have been introduced:
7532 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7533 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7535 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7537 * support/scripts/inc2h.pl: changed definition of BIT_AT
7538 to emit 'sbit at' instead of 'bit at'. This was a request.
7540 PIC16 port related preliminary changes:
7541 * gen.c: prefixed function popRegFromString with
7542 pic16_ and all references to it corrected
7543 * pcode.c: all pic16_pc_* hardware registers prefixed
7544 with underscore (_),
7545 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7546 * ralloc.c: newReg(): when register is REG_SFR then
7547 set address to rIdx,
7548 pic16_allocProcessorRegister(): marks register wasUsed=0
7549 pic16_writeUsedRegs(): added a call to assign processor
7550 registers via pic16_assignFixedRegisters
7552 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7554 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7555 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7556 variables in unused register banks. Also the SSEG is placed
7557 wherever there is enough space for it, and IDATA can be anywhere
7558 in internal RAM. For now compile using -Wl-Y[stack_size].
7559 The mem file is different for this option as well, since it
7560 makes no sense of talking about DSEG lenght.
7562 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7564 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7565 in certain cases, e.g. when ROM assignment, patch provided
7566 from Albert den Haan.

7807 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7809 * src/SDCCast.c (decorateType): disabled a transformation I added in
7810 revision 1.188 (access to fields of a structure at an absolute address);
7811 it breaks with bitfields, extern declarations, and gcse analysis.
7812 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7813 could be assigned through a pointer, so don't complain.
7814 * src/SDCCast.c (astErrors),
7816 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

7918 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
7919 uninitialized variables) for the mcs51. Set environment variable
7920 SDCC_GENRAMCLEAR to test.
7921 xdata initialization slightly shorter
7923 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8571 fetching of the pointer
8572 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8573 copied from genNearPointerSet()
8574 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8575 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

8591 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8592 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8593 type for bits was changed. It resulted in bit variables becoming
8594 global, which is not permitted in PIC 14 assembly output.

8611 A few small changes that speed up the peephole optimizer.
8615 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8617 Try to make the peephole optimizer smarter by maintaining
8618 an association between the assembly source code and the
8619 iCodes that originated them. Put this information to use
8620 with a new peephole rule condition "notVolatile" so that
8621 the rules can be aggressive yet still safe.
8626 * src/mcs51/peeph.def
8628 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8632 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8633 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8634 if the left or right operand symbols have the accuse flag set.
8636 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8638 Changed the type of the result of the ! (NOT) operator to char;
8639 previously it returned the same type as the source. This allows
8640 us to eliminate all the genFloatNot functions (all of its target
8641 implementations were very buggy) since !float can use the same

8654 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8655 during interrupts. Ensure WSAVE is located at a shared bank address.
8656 2. Fixed page selection in some places
8657 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8658 the registers name strings.
8659 4. Fixed "signed / unsigned compare" compiler warnings.
8660 5. The PIC port manages its own allocation of the general purpose
8661 registers, but makes no attempt to reuse them. As a result when
8662 compiling it soon runs out of general purpose registers. Some
8663 additional code was added to the files pcode.c and device.c to walk
8664 through the function call tree and rename the registers so that they
8674 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

8681 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8683 Made bitfield a distinct type from bit so that bitfields
8684 convert as per ANSI C and bits retain their traditional
8685 boolean style behaviour. Implemented bitfield support in
8693 * src/ds390/gen.c: bit v bitfield split
8694 * src/z80/gen.c: New support for bitfields
8695 * support/regression/tests/bitfields.c: reenabled z80,
8698 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8700 Rules 246.x, 247.x relate to bitfields, the others speed up
8701 access to xdata mapped I/O devices.
8703 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8705 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8707 Cleaned up genPackBits and genUnpackBits and added two helper
8708 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8709 for literal assignments in genPackBits (thanks to Frieder for
8715 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8717 Fixed bug #748310 (pointer to function type mishandled when the
8718 function name is omitted). Also fixed a SIGSEGV when a function
8719 attribute (reentrant, etc) is used on a non-function or on a
8720 function but misplaced before the parameter list.
8722 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8724 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

8747 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8749 Made the constant following the "interrupt" keyword optional. If
8750 omitted, the function will not automatically be given an entry
8751 in the interrupt vector table (similar to #pragma NOIV, but
8752 less syntacticly kludgy). The interrupt number is also now
8753 range checked. Also fixed a bug in the high order bit example

8767 * src/SDCCicode.c (operandOperation): rewritten some ops
8768 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8769 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8771 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8772 be re-activated by defining REDUCE_LITERALS)
8773 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8774 unsigned, but are signed by default
8775 * src/SDCCval.c (constVal): rearranged
8776 * src/SDCCval.c (valMod): preliminary fix
8777 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9282 * src/SDCCmain.c: linkOptions is changed to set *,
9283 added if/endif conditional macros to remove options help
9284 messages from optionsTable when a port is not configured, added
9285 support for the PIc16 port in the ports table, when executing
9286 the compiler with no port specified on command line, a default
9287 port is selected with the new macro DEFAULT_PORT which is
9288 defined in port.h, in setDefaultOptions() linkOptions is removed
9289 from initialization assignment, since now it is a set,
9290 parseCmdLine uses setParseWithComma for linkOptions, in
9291 linkEdit() linkOptions are accessed with new function indexSet()
9292 which returns the i'th item of a set variable. See SDCCset.c, in
9293 linkEdit() when calling buildCmdLine(), added linkOptions as
9294 last argument. Now users can pass arguments to gplink via the
9295 -Wl option, main() uses pic16glue() to glue up pic16 programs

9307 * src/pic16/glue.c: commented out some error producing lines
9308 * src/pic16/main.c: __config directives are commented out to stop
9309 gpasm complaining and test the linkage with gplink, _linkCmd and
9310 _asmCmd changed to be more gplink and gpasm friendly
9311 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9312 produced an error when parsed, peep rule 12 is added to utilize
9313 movff, but it is commented out since the pCode does not support
9314 yet a command with 2 address arguments
9316 2003-05-18 <johan AT balder>
9318 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9345 2003-05-11 Borut Razem <borut.razem AT siol.net>
9347 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9348 the path of bin directory, so that PATH is the only env. variable, which has to be set
9349 in case of standard installation.
9350 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10374 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10376 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10377 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10379 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10381 * in \sdcc\as\mcs51\ changed these files in order to create an
10382 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10383 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10384 following files to include the previous two files: aslink.dsp,
10385 Makefile.aslink, Makefile.bcc, and Makefile.in.
10387 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10388 .adb instead of .cdb
10390 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10392 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10393 value from option --iram-size.
10395 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10397 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10400 2002-09-18 <wiml AT hhhh.org>
10402 * SDCClrange.h: exposed setFromRange() and setToRange()
10403 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10404 packRegsForAccUse() (bug 542397)
10405 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10406 multiple times and emitting the fetch operations more than once
10407 added aopGetUsesAcc() function to allow binary operators to
10408 fetch their operands in the correct order; made genMinus() emit
10409 compact code for X = LITERAL - Y
10411 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10412 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10413 sprintf() in line 1267.
10415 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10416 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10419 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10420 Changes to aslink (All the changes are marked with 'JCF'):
10422 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10425 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10426 area BSEG. Also moves, if possible, the DATA area down into the internal
10427 ram so more space is available.
10429 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10432 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10433 not bytes. Function summary() which creates a memory usage summary
10434 file with extension .mem. Reports of overlaping stack and small stack
10435 size. If the space for the stack is less than 16 bytes aslink trows a
10438 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10439 the 8051. Option 'y' for memory summary output file.
10441 Changes to sdcc (All the changes are marked with 'JCF'):
10443 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10445 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10446 overlaying area for it (uses RegBankUsed[4]).
10448 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10449 bank zero as used by default. By default aslink locates the stack
10450 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10451 the creation of the .mem file. Delegates the allocation of data area
10452 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10453 the begining of the stack area to aslink.
10455 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10456 glue() in SDCCglue.c creates an area for it.
10458 2002-09-03 Borut Razem <borut.razem AT siol.net>
10459 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10460 sdcc/src/pic/glue.c:
10461 introduced atexit() handler for teporay files removal in case of
10462 errors, assertions, ...
10464 2002-08-29 Borut Razem <borut.razem AT siol.net>
10465 * sdcc/support/cpp2/auto-host_vc_in.h:
10466 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10467 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10468 Maybe there is a similar problem with BORLANDC? It should be checked!
10470 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10471 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10472 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10473 was not executed, and the compiler (cl) launched a warning:
10474 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10476 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10477 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10479 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10480 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10482 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10483 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10484 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10485 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10486 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10487 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10488 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10489 - added Release configuration in VS projects
10490 - review of compiler an linker options
10491 - VC .exe files are generated in bin_vc directory, not to interfere
10492 with binaries generated from other projects (cygwin, mingw, bcc ...)
10494 * sdcc/src/yacc.dsp: added
10496 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10497 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10498 and insert the version number definitions from .version
10500 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10502 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10503 added - genarate auto-host.h using auto-host_vc_in.h as template
10506 removed from CVS, generated automatically
10508 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10509 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10511 2002-08-11 Borut Razem <borut.razem AT siol.net>
10512 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10514 2002-08-10 Borut Razem <borut.razem AT siol.net>
10515 * src/SDCCmain.c (main):
10516 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10517 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10518 The consequence was that some temporary files were not removed.
10521 unification of code in functions tempfilename() and tempfile():
10522 function tempnam() is defined in Visual Studio 6.0 and .NET
10524 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10526 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10527 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10528 - removed compiler command line option /WX: Treats all warnings as errors
10529 - update a list of source files, included into the project
10531 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10532 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10533 changed project type to Generic Project so that can be correcly converted to VS.NET project
10535 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10537 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10539 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10541 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10542 added return 0 statements after assert() to make compiler happy
10544 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10545 added newline in the def file to keep MSC compiler satisfied
10547 * sdcc/src/z80/gen.c:
10548 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10549 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10550 - solved MSC error in function aopDump()
10552 * sdcc_vc.h: define PREFIX as "\\sdcc"
10554 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10555 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
10557 2002-06-22 Scott Dattalo <scott AT dattalo.com>
10558 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10559 - Rewrote the register banking algorithm.
10560 - Added pCode live-range analysis to registers (for now, only non-used and
10561 singly-used registers optimized away)
10563 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10565 * 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.

10590 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
10592 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10594 2002-03-28 Johan Knol <johan AT balder>
10596 * src/SDCCval.c: fixed bug #532436
10598 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10600 Added "char *Processor" field to the port structure.
10603 Added -p option. Allows port dependent processor to be specified.
10606 Initialized the new field char *Processor field to NULL in all ports
10609 Compiler generated registers for interrupt context saving
10610 were not getting allocated.
10612 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10615 Fixed left shift. Will promote the left side of a left shift
10616 if a) left shifting more than size of operand or b) when assigned
10617 to something size > size of left side
10619 2002-03-14 Scott Dattalo <scott AT dattalo.com>

10623 analysis is restructured. ...
10625 * src/pic/device.h:
10628 * src/pic/device.c:
10629 Added. device.c is a PIC port hack to accomodate variations
10632 2002-03-13 Michael Hope <michaelh AT vroom>
10634 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10636 2002-03-04 johanknol <johanknol AT manik>
10638 * /src/SDCCval.c: fixed
10640 const unsigned char arr[][2] = { { 0, 1 } };

10727 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10729 * sdcc/src/SDCCloop.c:
10730 Previous fix was not good. basic blocks that have "break" or "return" are
10731 not really partof a loop , but live ranges used in these blocks should
10732 be live thru the entire loop, so set partOfLoop but don't add them to
10735 2002-02-21 <johan AT FRIJA>
10737 * src/SDCCcse.c: fixed bug #514308
10739 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
10742 Fixed BUG #519583. If a conditional block ended in a return/break
