+ [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.
1.15. What's the problem with configure --enable-omitfp?
-{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.
+{} Removed. Does not apply anymore.
1.16. I get failures during `make check'. What should I do?

Don't build libraries with profiling information. You may want to
use this option if you don't plan to do profiling.
-`--enable-omitfp'
- Use maximum optimization for the normal (static and shared)
- libraries, and compile separate static libraries with debugging
- information and no optimization. We recommend not doing this.
- The extra optimization doesn't gain you much, it may provoke
- compiler bugs, and you won't be able to trace bugs through the C
- library.

`--disable-versioning'
Don't compile the shared libraries with symbol version information.
Doing this will make the resulting library incompatible with old

this: `CC=TARGET-gcc configure TARGET'. Set `BUILD_CC' to the compiler

Installing the C Library
========================
Check the FAQ for any special compiler issues on particular
platforms.
- * GNU `binutils'
+ * GNU `binutils' 2.15 or later
You must use GNU `binutils' (as and ld) to build the GNU C library.
No other assembler or linker has the necessary functionality at the
- moment. The configure scripts checks for the appropriate version
- for the platform. Too-old versions will prevent building glibc.
