+
+       * config/arm/telf.h (ASM_OUTPUT_SECTION_NAME): Add %nobits option
+       to .section when outputting a .bss section to deal with multiple
+       .bss input sections (as happens with -fdata-sections)
+       Also output %progbits, not @progbits so the assembler doesn't treat as
+       a comment.
+       * config/arm/unknown-elf.h (ASM_OUTPUT_SECTION_NAME): Likewise
+
+       * config/arm/lib1funcs.asm (_call_via_rX): Allow compilation of
+       thumb parts even when building with non-thumb CPUs, by forcing
+       thumb mode.     
+
 Wed Oct 20 22:57:58 1999  Jeffrey A Law  (law@cygnus.com)
 
        * sparc.md (movsf_const_intreg): If splitting, length must be > 1.
