Subject: [PATCH] * config.gcc (arm*-*-symbianelf*): Add t-symbian
Makefile fragment. * config/arm/bpabi.h (RENAME_LIBRARY_SET): Fix
typo. (SUBTARGET_EXTRA_ASM_SPEC): Pass -meabi=3 to the assembler. *
config/arm/symbian.h (SUBTARGET_CPU_DEFAULT): Assume ARMV5 architecture.
(SUBTARGET_ASM_FLOAT_SPEC): Default to -mfpu=vfp for hard-float
configurations. * config/arm/t-symbian: New file.
git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@86338 138bc75d-0d04-0410-961f-82ee72b054a4
