|
|
|
* rearrange the file structures of gcc. separate compiler from
|
|
libraries and header files. Here is the new structure:
|
|
|
|
1. static libraries are in /usr/lib.
|
|
2. jump table version of shared library stubs are in
|
|
/usr/lib/shlib/jump.
|
|
3. classic version of shared library stubs are in
|
|
/usr/lib/shlib/nojump
|
|
4. default for gcc is jump table. the other options are -nojump
|
|
and -static. -g and -pg will use the corresponding static
|
|
libraries.
|
|
|
|
* shared images are in a separate package.
|
|
|
|
* from this release on, the gcc will follow the FSF naming. the
|
|
libraries will be named after jump table version number. the
|
|
current versions are gcc 2.2.2d, the Linux C library 4.1 and
|
|
the Linux math library 4.0. the Linux math library won't change
|
|
with the minor version number. so for all the version y.xxx's,
|
|
there is only one release of math library, version `y.0'.
|
|
|
|
* file list for gcc 2.2.2d, libc 4.1 and libm 4.0:
|
|
|
|
1. 222d7.TZ
|
|
gcc 2.2.2d linked with jump table 4.1. it has gcc, cc1,
|
|
cc1plus and cpp. it also has version dependent header
|
|
files. unpack it under /.
|
|
|
|
2. lib41.tar
|
|
static libraries and shared library stubs. it has lib-4.1.TZ
|
|
and lib-4.1.sh. run lib-4.1.sh will install lib-4.1.TZ. do
|
|
|
|
lib-4.1.sh
|
|
|
|
you have to have a real sh to run it. This script is used to
|
|
install the math library, soft or hard.
|
|
|
|
3. inc-4.1.TZ
|
|
header files for lib 4.1. unpack it under /. You have to make
|
|
two symbolic links. one from include/linux of kernel source
|
|
to /usr/include/linux, another from include/asm of kernel
|
|
source to /usr/include/asm. There is a file,
|
|
/usr/include/linux/const.h. You have to move it to
|
|
include/linux of kernel source before you make symbolic link.
|
|
unpack it under /.
|
|
|
|
4. jump41.tar
|
|
shared images for jump table 4.1. it has jump-4.1.TZ and
|
|
jump-4.1.sh. do
|
|
|
|
jump-4.1.sh
|
|
|
|
to install jump-4.1.TZ. this script is used to install the
|
|
shared math image, soft or hard.
|
|
|
|
5. libdp-4.1.TZ
|
|
libc_p.a and libg.a. unpack it under /.
|
|
|
|
6. jump-src-4.1.TZ
|
|
scripts for build jump table 4.1. almost no documentations.
|
|
contributions are welcome.
|
|
|
|
7. lib-src-4.1.TZ
|
|
source code for the Linux C library 4.1.
|
|
|
|
* the install procedures are minimal. it didn't do much file
|
|
permission fixing. fix them when you find they are wrong.
|
|
|
|
* this release contains no new binaries for gcc, cc1, cc1plus or
|
|
cpp. only things changed are in libraries.
|
|

|
|
* gcc-2.2.2d
|
|
You need to have the header files from virgin Linux kernel 0.97 patch 1
|
|
or above on line to use this release.
|
|
The source codes for gcc itself is unchanged from 2.2.2, but it was
|
|
recompiled for new kernel. And lots of bugs are fixed.
|
|
|
|
I am trying to make the Linux C library to be POSIX.1 compliant. I
|
|
cleared up the header files and some library functions.
|
|
1. <limits.h> and <unistd.h> are fixed. (in 2.2.2dmisc.tar.Z)
|
|
2. <time.h> is fixed, remove __tzname_max (). (in 0.97pl1inc.tar.Z)
|
|
3. posix/sysconf.c. (the shared image is compiled with old one. I
|
|
don't think it will matter too much. this will be fixed in the
|
|
next release.)
|
|
4. time/Makefile (remove tzname.o)
|
|
|
|
There are some problems with pathconf()/fpathconf(). We need a new
|
|
sys call to get info about the filesystem. Someone mentioned
|
|
vfsstat (). It may be a good idea. To be compliance with POSIX.1, we
|
|
need
|
|
1. LINK_MAX
|
|
2. MAX_CANON
|
|
3. NAME_MAX
|
|
4. PATH_MAX
|
|
5. PIPE_BUF
|
|
6. _POSIX_CHOWN_RESTRICTED
|
|
7. _POSIX_NO_TRUNC
|
|
8. _POSIX_VDISABLE
|
|
Some of them may change for different filesystems. Some don't. Some may
|
|
do in the future.
|
|
|
|
The installation procedure is changed. Please read README first.
|
|
|
|
The new correct setjmp/longjmp are not compatible with gcc 2.2.2. If
|
|
your code uses them, please recompile it with gcc 2.2.2d. And
|
|
DO NOT USE setjmp/longjmp WITH THE SHARED X386 v1.1, WAIT FOR v2.0.
|
|
|
|
The following bugs in libraries are fixed.
|
|
1. div/ldiv.
|
|
2. setjmp/longjmp.
|
|
3. crt0.o/gcrt0.o. 387 control word is changed to 0x1272. No overflow
|
|
exception.
|
|
4. floating point format errors are fixed.
|
|
5. minor bug in mntent.c.
|
|
6. popen.o is fixed in libg.a.
|
|
7. fopen ("foo", "a") will seek to the end of file.
|
|
8. printf ("%10.2f\n", 10.0);
|
|
9. libg++.a 2.2 is used.
|
|
10. libinet.a is folded into libc.a. All the data bases are in
|
|
/usr/etc/inet. But you need kernel support for that. Please
|
|
contact "bir7@leland.stanford.edu" first.
|
|
11. a typo in libc-linux/socket/bytedorer.c is fixed.
|
|
12. size of args + envs for exec () is fixed.
|
|
13. new mount for 0.97.
|
|
14. a bug in temporary filename creation is fixed. Now it checks
|
|
if a process has permission to create a file in specified directory.
|
|
15. in libhard.a, pow (0.0, 0.0) = 1.0 now.
|
|
16. cc1/cc1plus is fixed for
|
|
double foo=DBL_MAX;
|
|
|
|
The following functions are added to libraries.
|
|
1. setpiority/getpiority.
|
|
2. iopl.
|
|
3. sigsetjmp/siglongjmp.
|
|
4. cfree.
|
|
|
|
The following changes are made to the header files.
|
|
You won't notice the changes unless you are testing TCP/IP. If you
|
|
are, please first contact "bir7@leland.stanford.edu". You need more
|
|
than that.
|
|
1. <stddef.h> is fixed.
|
|
2. <stdlib.h> is fixed.
|
|
3. all the header files are now compatible with gcc -traditional.
|
|
4. strncasecmp is added to <string.h>.
|
|
5. <sys/asy.h> is added.
|
|
6. lots of bugs are fixed.
|
|
7. <sys/user.h> and <a.out.h> are changed.
|
|
8. <sys/socket.h> and <fcntl.h> are changed for TCP/IP.
|
|
9. <sys/syslog.h> and <sgtty.h> are in for TCP/IP.
|
|
10. lots of header files in kernel and /usr/include are fixed.
|
|
|
|
two dummies, <sys/reg.h> and <machine/reg.h> are added for gdb 4.6.
|
|
|
|
The following changes are made to libraries.
|
|
1. byte order functions for networking are written in C. Please read
|
|
libc-linux/socket/byteorder.c and <netinet/in.h>
|
|
|
|
David's jump table version 2 release 2.1 is in.
|
|
|
|
Jun 27 1992
|
|
* gcc-2.2.2
|
|
Please get the new binutils.tar.Z, which fixed some bugs in as
|
|
and gprof with some patches from Rick Sladkey at jrs@world.std.com
|
|
I added some jumptable stubs to gcc. But I don't have the time to
|
|
implement it. In the future, you can use jump table with -jump in
|
|
CFLAGS.
|
|
Libg++.a is 2.2 beta.
|
|
This gcc will produce binaries only run safely under 0.96a patch level
|
|
4 or above.
|
|
|
|
The following bugs in libc.a are fixed.
|
|
1. hard and soft math libs are fixed. some of functions are totally
|
|
rewritten.
|
|
2. acosh, asinh and atanh are added to libsoft.a and math.h.
|
|
3. open a file for read and write, then do fseek followed by fwrite
|
|
works now.
|
|
4. now random () and srandom () are renamed to __random () and
|
|
__srandom (), respectively.
|
|
5. the header files taken from glibc.a are fixed.
|
|
6. the sys call mount now takes 4 args.
|
|
7. getpagesize and getdtablesize work now.
|
|
8. netdb.h, resolv.h, sys/uio.h, netinet.h, arpa/inet.h and
|
|
arpa/nameser.h are changed.
|
|
9. Some function declarations are added to sys/socket.h in
|
|
0.96bp2inc.tar.Z.
|
|
|
|
The following functions are added to libc.a.
|
|
1. profil.
|
|
2. libg.a is there.
|
|
3. getdtablesize.
|
|
4. lots of stuffs added to errno.h and string/errlist.c.
|
|
5. some changes in string/siglist.c.
|
|
6. dtoa.
|
|
7. there is a new strtod, please check it out.
|
|
8. drem.
|
|
9. the inet library functions are in libinet.a. They are untested. Once
|
|
they are tested ok, they will be moved to libc.a. All the inet
|
|
library functions are there, except for res_xxxx, rcmd, rexec and
|
|
ruserpass, which require more kernel support, like F_SETOWN, FASYNC,
|
|
and a few network system calls.
|
|
|
|
There should also be a set of files in /etc for inet functions. I
|
|
hope Ross will provide them.
|
|
|
|
In this release, there is a libc_p.a compiled with "-pg" for profiling.
|
|
|
|
You should use "-g" for debugging and "-pg/-p" for profiling in CFLAGS
|
|
when you compile the source code.
|
|
|
|
|
|
Jun 16 1992
|
|
|
|
* gcc-2.2 based on FSF release gcc-2.2.1
|
|
new binutils.tar.Z, which fixed some bugs in as.
|
|
Libg++.a is 2.1
|
|
A new structure of gcc is introduced here. All the static libs are in
|
|
/usr/lib/gcc-lib/i386-linux/2.xxx and all the shared libs are in
|
|
/usr/lib/gcc-lib/i386-linux/2.xxx/shared. By default, gcc will search
|
|
/usr/lib/gcc-lib/i386-linux/2.xxx/shared first, then the static libs.
|
|
You can turn off the shared libs with "-static".
|
|
|
|
The following bugs in libc.a are fixed.
|
|
1. dirent.[ch] are fixed such that static memory no longer is used in
|
|
readdir ().
|
|

|
|
4. gets () will only give a warning during linking.
|
|
5. wait3 ().

|
|
7. <sys/user.h> is added in 0.96ap2inc.tar.Z.
|
|
8. The return value of clock ticks of the old sysconf () was wrong. It
|
|
returned 60 instead of 100.
|
|
9. The domain errors in the math libraries are improved.
|
|
10. bsearch and qsort are fixed for zero element.
|
|
|

|
|
|
|
popen now is based on iostream.
|
|
|
|
I also changed the structure of header files.

|
|
May 30 1992
|
|
* gcc-2.12c based on ss-920528 from FSF
