| 6 | v3.2.2 Beta 1:
|
|---|
| 7 | --------------
|
|---|
| 8 |
|
|---|
| 9 | A few bugfixes and a some new features.
|
|---|
| 10 |
|
|---|
| 11 | o Locale support in libc.
|
|---|
| 12 |
|
|---|
| 13 | o Implmented a different approach to OMF and weak symbols. This new hack
|
|---|
| 14 | does a pre-linking before invoking the OMF linker generating new .def
|
|---|
| 15 | if needed and an extra object file with aliases to resolv the weak
|
|---|
| 16 | symbols correctly.
|
|---|
| 17 | The old approach used when GCC_WEAKSYMS is present in the environment.
|
|---|
| 18 |
|
|---|
| 19 | Please note that due to a bug in BFD weak symbols doesn't work 100%
|
|---|
| 20 | correctly. This will be addressed when we now move on to a later
|
|---|
| 21 | version of binutils.
|
|---|
| 22 |
|
|---|
| 23 | o A couple of new functions in libc, and a few correction of existing
|
|---|
| 24 | in respect to namespace.
|
|---|
| 25 |
|
|---|
| 26 | o Addressed issues with _System, _Optlink and __stdcall. They should
|
|---|
| 27 | all be working now.
|
|---|
| 28 |
|
|---|
| 29 | o Changed GCC to link with shared libc by default. This means that in
|
|---|
| 30 | order to link with static libc one have to specify -static.
|
|---|
| 31 | It also means that -Zmtd or -Zcrtdll is no longer required for linking
|
|---|
| 32 | with shared libc and can be removed from all makescripts.
|
|---|
| 33 |
|
|---|
| 34 | o Changed EMXOMFLD defaults to ilink from Visual Age for C++ v3.6.5 or
|
|---|
| 35 | later (preferably later). The emxomfld usage output will instruct you
|
|---|
| 36 | how how to use older linkers.
|
|---|
| 37 | Emxomf checks for EMXOMFLD_TYPE=link386 when choosing debug info level.
|
|---|
| 38 |
|
|---|
| 39 | o Shipping three extra libc dlls:
|
|---|
| 40 | libc02.dbg: Unstripped version of libc02.dll. This is identical
|
|---|
| 41 | except from the presense of debug info.
|
|---|
| 42 | libc02.prf: Linked together from profiled enabled libraries
|
|---|
| 43 | using kProfiler.
|
|---|
| 44 | libc02.elh: Standard libc but linked with an external eletrical
|
|---|
| 45 | fence heap from kLibDbg.
|
|---|
| 46 | These libc02.* dlls can be used instead of libc02.dll. kLibDbg and
|
|---|
| 47 | kProfiler is available in separate zip files at same location as the
|
|---|
| 48 | rest of the Innotek GCC suite. However these external tools are
|
|---|
| 49 | provided as is.
|
|---|
| 50 |
|
|---|
| 51 | o Distribution is splitted into several zips:
|
|---|
| 52 | -core.zip: All you really need.
|
|---|
| 53 | -dbg.zip: Map files, unstripped tools and libs, and libc02.elh.
|
|---|
| 54 | -prf.zip: Profiling libraries and libc02.prf.
|
|---|
| 55 | libc.zip: The runtime libraries. (included in core.)
|
|---|
| 56 | The big zips is everything.
|
|---|
| 57 |
|
|---|
| 58 | o I'm sure I've foregotten something this time....

|
|---|
| 61 | v3.2.2 Alpha 3:
|
|---|
| 62 | ---------------
|
|---|
| 63 |
|
|---|
| 64 | Primarily bugfixes.
|
|---|
| 65 |
|
|---|
| 66 | o Changed code generator for floating point truncations (double to int
|
|---|
| 67 | casts and such) so PM can freely mess up the fpu status.
|
|---|
| 68 |
|
|---|
| 69 | o We were using the wrong float.h in two sense. We're now using the
|
|---|
| 70 | correct one which includes all the PC defines and prototypes.
|
|---|
| 71 |
|
|---|
| 72 | o Fixed a few issues with error defines and tcpip.
|
|---|
| 73 | Note that some of the error defines have changed value in the process
|
|---|
| 74 | so we could become compatible with the tcpip stack and FreeBSD.
|
|---|
| 75 |
|
|---|
| 76 | o Corrected bugs in a number of headers.
|
|---|
| 77 |
|
|---|
| 78 | o Added more OS/2 prototypes and imports. There is still work left on
|
|---|
| 79 | the header part,
|
|---|
| 80 |
|
|---|
| 81 | o Optimized emxomf debug info conversion.
|
|---|
| 82 |
|
|---|
| 83 | o Wrapped bsdselect for BSD 4.4 header mode to implement bsdselect().
|
|---|
| 84 |
|
|---|
| 85 | o .... what did we forget...
|
|---|
| 86 |
|
|---|
| 87 |
|
|---|
| 88 | v3.2.2 Alpha 2:
|
|---|
| 89 | ---------------
|
|---|
| 90 |
|
|---|
| 91 | A few bugfixes and a couple of new features.
|
|---|
| 92 |
|
|---|
| 93 | o The TCP/IP headers and libraries scheme have been changed.
|
|---|
| 94 | The default is the current OS/2 tcpip toolkit (BSD 4.4 based).
|
|---|
| 95 | To target the older OS/2 tcpip stack (BSD 4.3 based) you must
|
|---|
| 96 | define TCPV40HDRS before including any TCP/IP headers and make
|
|---|
| 97 | sure usr/lib/tcpipv4 is searched before usr/lib (this is to get
|
|---|
| 98 | the right libsocket). It is recommended to use the -D compiler
|
|---|
| 99 | option for the define and either the LIBRARY_PATH or the -L
|
|---|
| 100 | compiler/linker option for the library.
|
|---|
| 101 |
|
|---|
| 102 | o There are a couple of new and updated based on FreeBSD 5.1.
|
|---|
| 103 | sys\stdint.h and inttypes.h (and a few internal once) are new.
|
|---|
| 104 | sys\types.h and unistd.h are the ones most heavily updated.
|
|---|
| 105 | We're working on getting the headers and libc in a better shape
|
|---|
| 106 | standardwise to easy compatability and portability.
|
|---|
| 107 |
|
|---|
| 108 | o A infinite loop in emxomf has been fixed.
|
|---|
| 109 |
|
|---|
| 110 | o Linker error on sopen() has been corrected.
|
|---|
| 111 |
|
|---|
| 112 | o .... what did we forget...
|
|---|
| 113 |
|
|---|
| 114 |
|
|---|
| 115 | v3.2.2 Alpha 1:
|
|---|
| 116 | ---------------
|
|---|
| 117 |
|
|---|
| 118 | This is the first release from Innotek, and it contains the Innotek LIBC.
|
|---|
| 119 | In addition to the new LIBC there is a number of other major changes:
|
|---|
| 120 |
|
|---|
| 121 | o Name mangling in OMF mode have changed.
|
|---|
| 122 | Until this release emxomf used to pretty much strip one leading '_'
|
|---|
| 123 | from symbols when converting them to omf. This is now longer done
|
|---|
| 124 | chiefly in order to correctly support mangling calling conventions
|
|---|
| 125 | like __stdcall and __cdecl. This change have the following side
|
|---|
| 126 | effects:
|
|---|
| 127 | - _System and __cdecl no longer produces the same names and hence
|
|---|
| 128 | all OS/2 API which are _System must be declared as _System in
|
|---|
| 129 | order to link.
|
|---|
| 130 | - Assembly code might need an extra underscore to work, or
|
|---|
| 131 | perhaps change the prototypes to _System.
|
|---|
| 132 | - Global variables are prepended and underscore, so mixing VAC and
|
|---|
| 133 | GCC, or accessing globals from asm, take care.
|
|---|
| 134 | (MSC v6.0 does this too, so it's not any uncommon practise.)
|
|---|
| 135 |
|
|---|
| 136 | The OS/2 headers which are included are all updated to use _System.
|
|---|
| 137 |
|
|---|
| 138 | o TCPIP headers are updated a quite a bit to match the toolkit ones
|
|---|
| 139 | and to reflect the fact that the new libc does not a having common
|
|---|
| 140 | handle space for files and sockets. These changes aren't 100%
|
|---|
| 141 | completed yet, and usage probably will uncover some issues left in
|
|---|
| 142 | there. Also for the programmer there is the following changes in
|
|---|
| 143 | the apis provided:
|
|---|
| 144 | - TCPV40HDRS are supported and should work like with the toolkit
|
|---|
| 145 | headers. It will alias all functions to tcpip40_ editions
|
|---|
| 146 | (using #defines) so we get the right imports thru -llibsocket.
|
|---|
| 147 | - There is no support for sockets in select(). To do select on
|
|---|
| 148 | sockets you will have to use bsdselect() or os2_select().
|
|---|
| 149 | bsdselect() is only available for TCPV40HDRS. For
|
|---|
| 150 | !defined(TCPV40HDRS) fd_set is in the emx/bsd format and not the
|
|---|
| 151 | OS/2 tcpip v5.0 format.
|
|---|
| 152 | - Socket IOCTLs are not supported by the ioctl() libc function
|
|---|
| 153 | because of the separate handle space for sockets. For sockets
|
|---|
| 154 | so_ioctl() and os2_ioctl() are used. os2_ioctl() is not available
|
|---|
| 155 | when TCPV40HDRS is defined. According to the tcpref in v5.0
|
|---|
| 156 | so_ioctl() only supports BSD ioctls.
|
|---|
| 157 | - writev() and readv() also clashes with libc. For socket handles
|
|---|
| 158 | use so_writev() and so_readv().
|
|---|
| 159 |
|
|---|
| 160 | o The prefered OMF linker is now ilink. link386 will fail with an odd
|
|---|
| 161 | error message if you tell gcc/g++ to make debug info. Set the
|
|---|
| 162 | EMXOMFLD_LINKER environment variable to value ilink in order to use
|
|---|
| 163 | ilink as OMF linker.
|
|---|
| 164 | It likely that we will change the default OMF linker to ilink in an
|
|---|
| 165 | later version of the GCC suite.
|
|---|
| 166 |
|
|---|
| 167 | o .... what did we forget...
|
