| [579] | 5 |
|
|---|
| 6 | v3.2.2 Beta 1:
|
|---|
| 7 | --------------
|
|---|
| [330] | 8 |
|
|---|
| [579] | 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 |
|
|---|
| [643] | 26 | o Addressed issues with calling conventions. We now detect incompatible
|
|---|
| 27 | calling conventions, emitting warnings and errors where appropritate.
|
|---|
| 28 |
|
|---|
| 29 | o _Optlink is much better, but there is still some issues left. Passing
|
|---|
| 30 | prototyped floating point parameters to _Optlink doesn't work. Mixing
|
|---|
| 31 | of parameters which goes into registers (eax,edx,ecx) and parameters
|
|---|
| 32 | which doesn't - void foo(int eax, struct sss s, int edx) - don't work.
|
|---|
| 33 | All these issues are being addressed and is expected to be fixed in
|
|---|
| 34 | the next build.
|
|---|
| 35 |
|
|---|
| [579] | 36 | o Changed GCC to link with shared libc by default. This means that in
|
|---|
| 37 | order to link with static libc one have to specify -static.
|
|---|
| 38 | It also means that -Zmtd or -Zcrtdll is no longer required for linking
|
|---|
| 39 | with shared libc and can be removed from all makescripts.
|
|---|
| 40 |
|
|---|
| 41 | o Changed EMXOMFLD defaults to ilink from Visual Age for C++ v3.6.5 or
|
|---|
| 42 | later (preferably later). The emxomfld usage output will instruct you
|
|---|
| [582] | 43 | how how to use older linkers. For VAC308 and VAC365 linkers /dbgpack
|
|---|
| 44 | is specified if debuginfo is to be generated.
|
|---|
| [579] | 45 | Emxomf checks for EMXOMFLD_TYPE=link386 when choosing debug info level.
|
|---|
| 46 |
|
|---|
| 47 | o Shipping three extra libc dlls:
|
|---|
| 48 | libc02.dbg: Unstripped version of libc02.dll. This is identical
|
|---|
| 49 | except from the presense of debug info.
|
|---|
| 50 | libc02.prf: Linked together from profiled enabled libraries
|
|---|
| 51 | using kProfiler.
|
|---|
| 52 | libc02.elh: Standard libc but linked with an external eletrical
|
|---|
| 53 | fence heap from kLibDbg.
|
|---|
| 54 | These libc02.* dlls can be used instead of libc02.dll. kLibDbg and
|
|---|
| 55 | kProfiler is available in separate zip files at same location as the
|
|---|
| 56 | rest of the Innotek GCC suite. However these external tools are
|
|---|
| [643] | 57 | provided as is. (I might actually not find time to put them out yet.)
|
|---|
| [579] | 58 |
|
|---|
| 59 | o Distribution is splitted into several zips:
|
|---|
| 60 | -core.zip: All you really need.
|
|---|
| 61 | -dbg.zip: Map files, unstripped tools and libs, and libc02.elh.
|
|---|
| 62 | -prf.zip: Profiling libraries and libc02.prf.
|
|---|
| 63 | libc.zip: The runtime libraries. (included in core.)
|
|---|
| [643] | 64 | The big zip is everything.
|
|---|
| [579] | 65 |
|
|---|
| 66 | o I'm sure I've foregotten something this time....
|
|---|
| 67 |
|
|---|
| [330] | 68 |
|
|---|
| [399] | 69 | v3.2.2 Alpha 3:
|
|---|
| 70 | ---------------
|
|---|
| 71 |
|
|---|
| [579] | 72 | Primarily bugfixes.
|
|---|
| 73 |
|
|---|
| 74 | o Changed code generator for floating point truncations (double to int
|
|---|
| 75 | casts and such) so PM can freely mess up the fpu status.
|
|---|
| 76 |
|
|---|
| 77 | o We were using the wrong float.h in two sense. We're now using the
|
|---|
| 78 | correct one which includes all the PC defines and prototypes.
|
|---|
| 79 |
|
|---|
| 80 | o Fixed a few issues with error defines and tcpip.
|
|---|
| 81 | Note that some of the error defines have changed value in the process
|
|---|
| 82 | so we could become compatible with the tcpip stack and FreeBSD.
|
|---|
| 83 |
|
|---|
| 84 | o Corrected bugs in a number of headers.
|
|---|
| 85 |
|
|---|
| 86 | o Added more OS/2 prototypes and imports. There is still work left on
|
|---|
| 87 | the header part,
|
|---|
| 88 |
|
|---|
| 89 | o Optimized emxomf debug info conversion.
|
|---|
| 90 |
|
|---|
| 91 | o Wrapped bsdselect for BSD 4.4 header mode to implement bsdselect().
|
|---|
| 92 |
|
|---|
| [399] | 93 | o .... what did we forget...
|
|---|
| [579] | 94 |
|
|---|
| [399] | 95 |
|
|---|
| [365] | 96 | v3.2.2 Alpha 2:
|
|---|
| 97 | ---------------
|
|---|
| [579] | 98 |
|
|---|
| 99 | A few bugfixes and a couple of new features.
|
|---|
| 100 |
|
|---|
| 101 | o The TCP/IP headers and libraries scheme have been changed.
|
|---|
| 102 | The default is the current OS/2 tcpip toolkit (BSD 4.4 based).
|
|---|
| 103 | To target the older OS/2 tcpip stack (BSD 4.3 based) you must
|
|---|
| 104 | define TCPV40HDRS before including any TCP/IP headers and make
|
|---|
| 105 | sure usr/lib/tcpipv4 is searched before usr/lib (this is to get
|
|---|
| 106 | the right libsocket). It is recommended to use the -D compiler
|
|---|
| 107 | option for the define and either the LIBRARY_PATH or the -L
|
|---|
| 108 | compiler/linker option for the library.
|
|---|
| [365] | 109 |
|
|---|
| [579] | 110 | o There are a couple of new and updated based on FreeBSD 5.1.
|
|---|
| 111 | sys\stdint.h and inttypes.h (and a few internal once) are new.
|
|---|
| 112 | sys\types.h and unistd.h are the ones most heavily updated.
|
|---|
| 113 | We're working on getting the headers and libc in a better shape
|
|---|
| 114 | standardwise to easy compatability and portability.
|
|---|
| 115 |
|
|---|
| 116 | o A infinite loop in emxomf has been fixed.
|
|---|
| 117 |
|
|---|
| 118 | o Linker error on sopen() has been corrected.
|
|---|
| 119 |
|
|---|
| [365] | 120 | o .... what did we forget...
|
|---|
| [579] | 121 |
|
|---|
| 122 |
|
|---|
| [330] | 123 | v3.2.2 Alpha 1:
|
|---|
| 124 | ---------------
|
|---|
| [579] | 125 |
|
|---|
| [330] | 126 | This is the first release from Innotek, and it contains the Innotek LIBC.
|
|---|
| [579] | 127 | In addition to the new LIBC there is a number of other major changes:
|
|---|
| [330] | 128 |
|
|---|
| 129 | o Name mangling in OMF mode have changed.
|
|---|
| 130 | Until this release emxomf used to pretty much strip one leading '_'
|
|---|
| 131 | from symbols when converting them to omf. This is now longer done
|
|---|
| 132 | chiefly in order to correctly support mangling calling conventions
|
|---|
| 133 | like __stdcall and __cdecl. This change have the following side
|
|---|
| 134 | effects:
|
|---|
| 135 | - _System and __cdecl no longer produces the same names and hence
|
|---|
| 136 | all OS/2 API which are _System must be declared as _System in
|
|---|
| 137 | order to link.
|
|---|
| 138 | - Assembly code might need an extra underscore to work, or
|
|---|
| 139 | perhaps change the prototypes to _System.
|
|---|
| 140 | - Global variables are prepended and underscore, so mixing VAC and
|
|---|
| 141 | GCC, or accessing globals from asm, take care.
|
|---|
| 142 | (MSC v6.0 does this too, so it's not any uncommon practise.)
|
|---|
| 143 |
|
|---|
| 144 | The OS/2 headers which are included are all updated to use _System.
|
|---|
| 145 |
|
|---|
| 146 | o TCPIP headers are updated a quite a bit to match the toolkit ones
|
|---|
| 147 | and to reflect the fact that the new libc does not a having common
|
|---|
| 148 | handle space for files and sockets. These changes aren't 100%
|
|---|
| 149 | completed yet, and usage probably will uncover some issues left in
|
|---|
| 150 | there. Also for the programmer there is the following changes in
|
|---|
| 151 | the apis provided:
|
|---|
| 152 | - TCPV40HDRS are supported and should work like with the toolkit
|
|---|
| 153 | headers. It will alias all functions to tcpip40_ editions
|
|---|
| 154 | (using #defines) so we get the right imports thru -llibsocket.
|
|---|
| 155 | - There is no support for sockets in select(). To do select on
|
|---|
| 156 | sockets you will have to use bsdselect() or os2_select().
|
|---|
| 157 | bsdselect() is only available for TCPV40HDRS. For
|
|---|
| 158 | !defined(TCPV40HDRS) fd_set is in the emx/bsd format and not the
|
|---|
| 159 | OS/2 tcpip v5.0 format.
|
|---|
| 160 | - Socket IOCTLs are not supported by the ioctl() libc function
|
|---|
| 161 | because of the separate handle space for sockets. For sockets
|
|---|
| 162 | so_ioctl() and os2_ioctl() are used. os2_ioctl() is not available
|
|---|
| 163 | when TCPV40HDRS is defined. According to the tcpref in v5.0
|
|---|
| 164 | so_ioctl() only supports BSD ioctls.
|
|---|
| 165 | - writev() and readv() also clashes with libc. For socket handles
|
|---|
| 166 | use so_writev() and so_readv().
|
|---|
| 167 |
|
|---|
| 168 | o The prefered OMF linker is now ilink. link386 will fail with an odd
|
|---|
| 169 | error message if you tell gcc/g++ to make debug info. Set the
|
|---|
| 170 | EMXOMFLD_LINKER environment variable to value ilink in order to use
|
|---|
| 171 | ilink as OMF linker.
|
|---|
| 172 | It likely that we will change the default OMF linker to ilink in an
|
|---|
| 173 | later version of the GCC suite.
|
|---|
| 174 |
|
|---|
| 175 | o .... what did we forget...
|
|---|
