[BZ #13552]
|
||||
* configure.in: Remove --enable-omitfp support.
|
||||
* FAQ.in: Adjust.
|
||||
* config.make.in: Likewise.
|
||||
* Makeconfig: Likewise.
|
||||
* manual/install.texi: Likewise.
|
||||
|
||||
In case anyone cares, the IA-64 architecture could move to ports.
|
||||
* sysdeps/ia64/*: Removed.
|
||||
* sysdeps/unix/sysv/linux/ia64/*: Removed.

{AJ} When --enable-omitfp is set the libraries are built without frame

pointers. Some compilers produce buggy code for this model and therefore we

don't advise using it at the moment.

If you use --enable-omitfp, you're on your own. If you encounter problems
|

with a library that was build this way, we advise you to rebuild the library
|
||||
without --enable-omitfp. If the problem vanishes consider tracking the
|
||||
problem down and report it as compiler failure.
|

Since a library built with --enable-omitfp is undebuggable on most systems,
|
||||
debuggable libraries are also built - you can use them by appending "_g" to
|
||||
the library names.

The compilation of these extra libraries and the compiler optimizations slow

down the build process and need more disk space.
