| 6 | v3.2.2 Beta 3:
|
|---|
| 7 | --------------
|
|---|
| 8 |
|
|---|
| 9 | A few new features and fixes.
|
|---|
| 10 |
|
|---|
| 11 | o Fixed a bunch of debug info problems.
|
|---|
| 12 |
|
|---|
| 13 | o Added large file file support.
|
|---|
| 14 |
|
|---|
| 15 | o Enabled high memory suppor for LIBC. Two new option to GCC -Zhigh-mem
|
|---|
| 16 | and -Zhigh-low. If the program is enabled for high memory use
|
|---|
| 17 | -Zhigh-mem when linking.
|
|---|
| 18 |
|
|---|
| 19 | Note. that socket is not enabled yet.
|
|---|
| 20 |
|
|---|
| 21 | o Made LIBC preserve the FS selector.
|
|---|
| 22 |
|
|---|
| 23 | o Fixed crash with link386 and unresolved symbols.
|
|---|
| 24 |
|
|---|
| 25 | o A few other problem which is mentioned in the change log.
|
|---|
| 26 |
|
|---|
| 27 |
|
|---|
| 28 | v3.2.2 Beta 2:
|
|---|
| 29 | --------------
|
|---|
| 30 |
|
|---|
| 31 | A few bugfixes and a some new features (as usual).
|
|---|
| 32 |
|
|---|
| 33 | o Added file locking support to LIBC.
|
|---|
| 34 |
|
|---|
| 35 | o Fixed _System and _Optlink bugs and made _Optlink support floating
|
|---|
| 36 | point arguments passing in registers.
|
|---|
| 37 |
|
|---|
| 38 | o Header updates related to limits and file locking primarily.
|
|---|
| 39 |
|
|---|
| 40 | o Timezone fixes.
|
|---|
| 41 |
|
|---|
| 42 | o Fixed some CRT init trouble in regards to getenv and putenv.
|
|---|
| 43 |
|
|---|
| 44 | o And some other minor stuff..
|
|---|
| 45 |
|
|---|
| 46 |
|
|---|
| 47 | v3.2.2 Beta 1:
|
|---|
| 48 | --------------
|
|---|
| 49 |
|
|---|
| 50 | A few bugfixes and a some new features.
|
|---|
| 51 |
|
|---|
| 52 | o Locale support in libc.
|
|---|
| 53 |
|
|---|
| 54 | o Implmented a different approach to OMF and weak symbols. This new hack
|
|---|
| 55 | does a pre-linking before invoking the OMF linker generating new .def
|
|---|
| 56 | if needed and an extra object file with aliases to resolv the weak
|
|---|
| 57 | symbols correctly.
|
|---|
| 58 | The old approach used when GCC_WEAKSYMS is present in the environment.
|
|---|
| 59 |
|
|---|
| 60 | Please note that due to a bug in BFD weak symbols doesn't work 100%
|
|---|
| 61 | correctly. This will be addressed when we now move on to a later
|
|---|
| 62 | version of binutils.
|
|---|
| 63 |
|
|---|
| 64 | o A couple of new functions in libc, and a few correction of existing
|
|---|
| 65 | in respect to namespace.
|
|---|
| 66 |
|
|---|
| 67 | o Addressed issues with calling conventions. We now detect incompatible
|
|---|
| 68 | calling conventions, emitting warnings and errors where appropritate.
|
|---|
| 69 |
|
|---|
| 70 | o _Optlink is much better, but there is still some issues left. Passing
|
|---|
| 71 | prototyped floating point parameters to _Optlink doesn't work. Mixing
|
|---|
| 72 | of parameters which goes into registers (eax,edx,ecx) and parameters
|
|---|
| 73 | which doesn't - void foo(int eax, struct sss s, int edx) - don't work.
|
|---|
| 74 | All these issues are being addressed and is expected to be fixed in
|
|---|
| 75 | the next build.
|
|---|
| 76 |
|
|---|
| 77 | o Changed GCC to link with shared libc by default. This means that in
|
|---|
| 78 | order to link with static libc one have to specify -static.
|
|---|
| 79 | It also means that -Zmtd or -Zcrtdll is no longer required for linking
|
|---|
| 80 | with shared libc and can be removed from all makescripts.
|
|---|
| 81 |
|
|---|
| 82 | o Changed EMXOMFLD defaults to ilink from Visual Age for C++ v3.6.5 or
|
|---|
| 83 | later (preferably later). The emxomfld usage output will instruct you
|
|---|
| 84 | how how to use older linkers. For VAC308 and VAC365 linkers /dbgpack
|
|---|
| 85 | is specified if debuginfo is to be generated.
|
|---|
| 86 | Emxomf checks for EMXOMFLD_TYPE=link386 when choosing debug info level.
|
|---|
| 87 |
|
|---|
| 88 | o Shipping three extra libc dlls:
|
|---|
| 89 | libc02.dbg: Unstripped version of libc02.dll. This is identical
|
|---|
| 90 | except from the presense of debug info.
|
|---|
| 91 | libc02.prf: Linked together from profiled enabled libraries
|
|---|
| 92 | using kProfiler.
|
|---|
| 93 | libc02.elh: Standard libc but linked with an external eletrical
|
|---|
| 94 | fence heap from kLibDbg.
|
|---|
| 95 | These libc02.* dlls can be used instead of libc02.dll. kLibDbg and
|
|---|
| 96 | kProfiler is available in separate zip files at same location as the
|
|---|
| 97 | rest of the Innotek GCC suite. However these external tools are
|
|---|
| 98 | provided as is. (I might actually not find time to put them out yet.)
|
|---|
| 99 |
|
|---|
| 100 | o Distribution is splitted into several zips:
|
|---|
| 101 | -core.zip: All you really need.
|
|---|
| 102 | -dbg.zip: Map files, unstripped tools and libs, and libc02.elh.
|
|---|
| 103 | -prf.zip: Profiling libraries and libc02.prf.
|
|---|
| 104 | libc.zip: The runtime libraries. (included in core.)
|
|---|
| 105 | The big zip is everything.
|
|---|
| 106 |
|
|---|
| 107 | o I'm sure I've foregotten something this time....
|
|---|
| 108 |
|
|---|
| 109 |
|
|---|
| 110 | v3.2.2 Alpha 3:
|
|---|
| 111 | ---------------
|
|---|
| 112 |
|
|---|
| 113 | Primarily bugfixes.
|
|---|
| 114 |
|
|---|
| 115 | o Changed code generator for floating point truncations (double to int
|
|---|
| 116 | casts and such) so PM can freely mess up the fpu status.
|
|---|
| 117 |
|
|---|
| 118 | o We were using the wrong float.h in two sense. We're now using the
|
|---|
| 119 | correct one which includes all the PC defines and prototypes.
|
|---|
| 120 |
|
|---|
| 121 | o Fixed a few issues with error defines and tcpip.
|
|---|
| 122 | Note that some of the error defines have changed value in the process
|
|---|
| 123 | so we could become compatible with the tcpip stack and FreeBSD.
|
|---|
| 124 |
|
|---|
| 125 | o Corrected bugs in a number of headers.
|
|---|
| 126 |
|
|---|
| 127 | o Added more OS/2 prototypes and imports. There is still work left on
|
|---|
| 128 | the header part,
|
|---|
| 129 |
|
|---|
| 130 | o Optimized emxomf debug info conversion.
|
|---|
| 131 |
|
|---|
| 132 | o Wrapped bsdselect for BSD 4.4 header mode to implement bsdselect().
|
|---|
| 133 |
|
|---|
| 134 | o .... what did we forget...
|
|---|
| 135 |
|
|---|
| 136 |
|
|---|
| 137 | v3.2.2 Alpha 2:
|
|---|
| 138 | ---------------
|
|---|
| 139 |
|
|---|
| 140 | A few bugfixes and a couple of new features.
|
|---|
| 141 |
|
|---|
| 142 | o The TCP/IP headers and libraries scheme have been changed.
|
|---|
| 143 | The default is the current OS/2 tcpip toolkit (BSD 4.4 based).
|
|---|
| 144 | To target the older OS/2 tcpip stack (BSD 4.3 based) you must
|
|---|
| 145 | define TCPV40HDRS before including any TCP/IP headers and make
|
|---|
| 146 | sure usr/lib/tcpipv4 is searched before usr/lib (this is to get
|
|---|
| 147 | the right libsocket). It is recommended to use the -D compiler
|
|---|
| 148 | option for the define and either the LIBRARY_PATH or the -L
|
|---|
| 149 | compiler/linker option for the library.
|
|---|
| 150 |
|
|---|
| 151 | o There are a couple of new and updated based on FreeBSD 5.1.
|
|---|
| 152 | sys\stdint.h and inttypes.h (and a few internal once) are new.
|
|---|
| 153 | sys\types.h and unistd.h are the ones most heavily updated.
|
|---|
| 154 | We're working on getting the headers and libc in a better shape
|
|---|
| 155 | standardwise to easy compatability and portability.
|
|---|
| 156 |
|
|---|
| 157 | o A infinite loop in emxomf has been fixed.
|
|---|
| 158 |
|
|---|
| 159 | o Linker error on sopen() has been corrected.
|
|---|
| 160 |
|
|---|
| 161 | o .... what did we forget...
|
|---|
| 162 |
|
|---|
| 163 |
|
|---|
| 164 | v3.2.2 Alpha 1:
|
|---|
| 165 | ---------------
|
|---|
| 166 |
|
|---|
| 167 | This is the first release from Innotek, and it contains the Innotek LIBC.
|
|---|
| 168 | In addition to the new LIBC there is a number of other major changes:
|
|---|
| 169 |
|
|---|
| 170 | o Name mangling in OMF mode have changed.
|
|---|
| 171 | Until this release emxomf used to pretty much strip one leading '_'
|
|---|
| 172 | from symbols when converting them to omf. This is now longer done
|
|---|
| 173 | chiefly in order to correctly support mangling calling conventions
|
|---|
| 174 | like __stdcall and __cdecl. This change have the following side
|
|---|
| 175 | effects:
|
|---|
| 176 | - _System and __cdecl no longer produces the same names and hence
|
|---|
| 177 | all OS/2 API which are _System must be declared as _System in
|
|---|
| 178 | order to link.
|
|---|
| 179 | - Assembly code might need an extra underscore to work, or
|
|---|
| 180 | perhaps change the prototypes to _System.
|
|---|
| 181 | - Global variables are prepended and underscore, so mixing VAC and
|
|---|
| 182 | GCC, or accessing globals from asm, take care.
|
|---|
| 183 | (MSC v6.0 does this too, so it's not any uncommon practise.)
|
|---|
| 184 |
|
|---|
| 185 | The OS/2 headers which are included are all updated to use _System.
|
|---|
| 186 |
|
|---|
| 187 | o TCPIP headers are updated a quite a bit to match the toolkit ones
|
|---|
| 188 | and to reflect the fact that the new libc does not a having common
|
|---|
| 189 | handle space for files and sockets. These changes aren't 100%
|
|---|
| 190 | completed yet, and usage probably will uncover some issues left in
|
|---|
| 191 | there. Also for the programmer there is the following changes in
|
|---|
| 192 | the apis provided:
|
|---|
| 193 | - TCPV40HDRS are supported and should work like with the toolkit
|
|---|
| 194 | headers. It will alias all functions to tcpip40_ editions
|
|---|
| 195 | (using #defines) so we get the right imports thru -llibsocket.
|
|---|
| 196 | - There is no support for sockets in select(). To do select on
|
|---|
| 197 | sockets you will have to use bsdselect() or os2_select().
|
|---|
| 198 | bsdselect() is only available for TCPV40HDRS. For
|
|---|
| 199 | !defined(TCPV40HDRS) fd_set is in the emx/bsd format and not the
|
|---|
| 200 | OS/2 tcpip v5.0 format.
|
|---|
| 201 | - Socket IOCTLs are not supported by the ioctl() libc function
|
|---|
| 202 | because of the separate handle space for sockets. For sockets
|
|---|
| 203 | so_ioctl() and os2_ioctl() are used. os2_ioctl() is not available
|
|---|
| 204 | when TCPV40HDRS is defined. According to the tcpref in v5.0
|
|---|
| 205 | so_ioctl() only supports BSD ioctls.
|
|---|
| 206 | - writev() and readv() also clashes with libc. For socket handles
|
|---|
| 207 | use so_writev() and so_readv().
|
|---|
| 208 |
|
|---|
| 209 | o The prefered OMF linker is now ilink. link386 will fail with an odd
|
|---|
| 210 | error message if you tell gcc/g++ to make debug info. Set the
|
|---|
| 211 | EMXOMFLD_LINKER environment variable to value ilink in order to use
|
|---|
| 212 | ilink as OMF linker.
|
|---|
| 213 | It likely that we will change the default OMF linker to ilink in an
|
|---|
| 214 | later version of the GCC suite.
|
|---|
| 215 |
|
|---|
| 216 | o .... what did we forget...
|
|---|
