2 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5 2002-09-04 Jesus Calvino-Fraga <jesusc@ece.ubc.ca>
6 Changes to aslink (All the changes are marked with 'JCF'):
8 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
11 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
12 area BSEG. Also moves, if possible, the DATA area down into the internal
13 ram so more space is available.
15 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
18 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
19 not bytes. Function summary() which creates a memory usage summary
20 file with extension .mem. Reports of overlaping stack and small stack
21 size. If the space for the stack is less than 16 bytes aslink trows a
24 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
25 the 8051. Option 'y' for memory summary output file.
27 Changes to sdcc (All the changes are marked with 'JCF'):
29 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
31 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
32 overlaying area for it (uses RegBankUsed[4]).
34 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
35 bank zero as used by default. By default aslink locates the stack
36 (equivalent to --stack-after-data). Pass option 'y' to aslink for
37 the creation of the .mem file. Delegates the allocation of data area
38 to aslink (it is not longer 0x30 by default). If --stack-loc passes
39 the begining of the stack area to aslink.
41 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
42 glue() in SDCCglue.c creates an area for it.
44 2002-09-03 Borut Razem <borut.razem@siol.net>
45 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
47 introduced atexit() handler for teporay files removal in case of
48 errors, assertions, ...
50 2002-08-29 Borut Razem <borut.razem@siol.net>
51 * sdcc/support/cpp2/auto-host_vc_in.h:
52 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
53 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
54 Maybe there is a similar problem with BORLANDC? It should be checked!
56 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
57 corrected improper use of assert: the assignment to clr variable was done inside the assert.
58 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
59 was not executed, and the compiler (cl) launched a warning:
60 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
62 2002-08-28 Bernhard Held <bernhard@bernhardheld.de>
63 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
65 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem@siol.net>
66 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
68 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
69 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
70 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
71 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
72 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
73 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
74 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
75 - added Release configuration in VS projects
76 - review of compiler an linker options
77 - VC .exe files are generated in bin_vc directory, not to interfere
78 with binaries generated from other projects (cygwin, mingw, bcc ...)
80 * sdcc/src/yacc.dsp: added
82 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
83 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
84 and insert the version number definitions from .version
86 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
88 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
89 added - genarate auto-host.h using auto-host_vc_in.h as template
92 removed from CVS, generated automatically
94 2002-08-25 Bernhard Held <bernhard@bernhardheld.de>
95 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
97 2002-08-11 Borut Razem <borut.razem@siol.net>
98 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
100 2002-08-10 Borut Razem <borut.razem@siol.net>
101 * src/SDCCmain.c (main):
102 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
103 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
104 The consequence was that some temporary files were not removed.
107 unification of code in functions tempfilename() and tempfile():
108 function tempnam() is defined in Visual Studio 6.0 and .NET
110 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
112 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
113 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:

115 - update a list of source files, included into the project
117 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
118 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
119 changed project type to Generic Project so that can be correcly converted to VS.NET project
121 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
123 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
125 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
127 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
128 added return 0 statements after assert() to make compiler happy
130 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
131 added newline in the def file to keep MSC compiler satisfied
133 * sdcc/src/z80/gen.c:
134 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
135 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
136 - solved MSC error in function aopDump()
138 * sdcc_vc.h: define PREFIX as "\\sdcc"
140 2002-07-18 Bernhard Held <bernhard@bernhardheld.de>
141 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

145 - Rewrote the register banking algorithm.
146 - Added pCode live-range analysis to registers (for now, only non-used and
147 singly-used registers optimized away)
149 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
151 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba@cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.
153 2002-05-10 Scott Dattalo <scott@dattalo.com>

189 Added -p option. Allows port dependent processor to be specified.
192 Initialized the new field char *Processor field to NULL in all ports
195 Compiler generated registers for interrupt context saving
196 were not getting allocated.
198 2002-03-16 Sandeep Dutta <sandeep@ddi.com>
201 Fixed left shift. Will promote the left side of a left shift
202 if a) left shifting more than size of operand or b) when assigned
203 to something size > size of left side
205 2002-03-14 Scott Dattalo <scott@dattalo.com>
207 tons of changes. Register allocation has been
208 rewritten. Added customization for the various PICs. Flow
209 analysis is restructured. ...
215 Added. device.c is a PIC port hack to accomodate variations

313 2002-02-21 Sandeep Dutta <sandeep@ddi.com>
315 * sdcc/src/SDCCloop.c:
316 Previous fix was not good. basic blocks that have "break" or "return" are
317 not really partof a loop , but live ranges used in these blocks should
318 be live thru the entire loop, so set partOfLoop but don't add them to
321 2002-02-21 <johan@FRIJA>
323 * src/SDCCcse.c: fixed bug #514308
325 2002-02-20 Sandeep Dutta <sandeep@ddi.com>

344 for use as a multiple module SDCDB test case.
346 * sim/ucsim/cmd.src/cmdset.cc:
347 Took out debug printfs in ucsim "next" command.
350 Karl and Johan start ucsim XA support. Most dissassembly working,
351 about 75% emulation done(plenty of work remaining).
354 Add Z80 support to ucsim, add test-ucz80 regression test,
355 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
356 Notice z80 compiler fails on examples/test3.c/crc code.
358 2002-01-30 Sandeep Dutta <sandeep@ddi.com>
