+
+ * config.gcc (sparc*-*-*): Always set need_64bit_hwint to yes.
+ (sparc*-*-linux*): Use linux.h in tm_file.
+ (sparc-*-linux*): If 'enabled_targets' is 'all', build a bi-arch
+ compiler defaulting to 32-bit.
+ (sparc*-*-*): Remove explicit target settings of need_64bit_hwint,
+ no longer needed.
+ * config/sparc/linux.h: Remove definitions now obtained
+ properly from linux.h
+ * config/sparc/linux64.h: Likewise.
+ (ASM_CPU_DEFAULT_SPEC): Change this to ASM_CPU64_DEFAULT_SPEC, we
+ don't want this setting for 32-bit builds in a biarch compiler.
+ * doc/install.texi: Add sparc-linux to list of targets
+ supporting --enable-targets=all.
+
2008-05-03 Andrew Pinski <pinskia@gmail.com>
* Makefile.in (tree-ssa-phiprop.o): Fix dependencies.
